The chains are connected to wheels on a shaft that is oscillated back and forth, causing the rods and heads to move up and down in a tramping motion to pack the sliver. This mechanism eliminates extending levers and allows for close spacing of the cans. Diagrams show two embodiments using springs or weights to assist the up and down motion of the rods and heads.
This document describes improvements to ion traps in cathode-ray tubes. Specifically, it describes a cathode-ray tube design where the axis of the tubular anode adjacent to the cathode is not coaxial with but intersects the common axis of preceding electrodes. This allows the ion trap to operate satisfactorily while avoiding disadvantages of prior designs that required the anode to have a coaxial part. The new design allows for a shorter overall electrode system length compared to prior bent anode designs.
This document describes a patent for improvements in the production of molds and cores. Specifically, it involves a process where a mixture of sand and gas-hardenable binder is blown into a mold or core box. A gaseous hardening agent is then applied to the mixture as it enters the mold box. This allows the molds and cores to be formed and hardened rapidly. The document provides detailed descriptions of the process and apparatus used, including the use of a venturi tube-shaped orifice in the blowing plate to control where the hardening agent is introduced.
This document describes a preparation and process for permanently changing the shape of hair, such as imparting a permanent wave, using a reducing solution containing a mercaptan (such as thioglycollic acid), a sulphite, and formamide or a substituted formamide (such as urea). Applying the solution to hair wrapped in curlers and heating it to 40-60°C (tepid waving) allows the concentration of mercaptan to be substantially reduced compared to conventional preparations while still effectively changing the hair shape. The preparation pH is preferably 9-10 and concentrations of ingredients like mercaptan, sulphite and formamide or substitute are provided.
This document describes an apparatus for measuring high rotational speeds ranging from 2500 to 30000 RPM. The apparatus uses a cathode ray oscilloscope connected to an electromagnetic impulse generator attached to the rotating member. This causes the spot on the oscilloscope to move in a circular pattern proportional to the rotational speed. Timing circuits switch the spot on to create a short spiral trace indicating the broad speed range, then off. After a delay, the spot is switched on briefly to create a dot, indicating the precise speed within the range.
This document describes a lubricant composition for aviation gas turbine engines. The composition includes a blend of dinonyl sebacate and di-2-ethyl hexyl sebacate as the major components. It also includes a complex ester in the amount of 10-30% by volume to increase viscosity and improve high temperature performance. Additionally, it contains an oxygen-containing polymer such as polyacrylate in the amount of 20% by weight to further improve properties.
This document describes improvements to teaching apparatus for elementary arithmetic instruction. The apparatus uses a rigid board with numerical scales and movable counters to teach counting and basic arithmetic operations. Key improvements include omitting or outlining numerical symbols on the scales so students fill them in as they move counters. Counters are also marked with arrows or other symbols to associate direction of movement with addition and subtraction. Having irregular edges on the board conveys the infinite nature of numbers to students.
This document summarizes a patent for an apparatus that stores digital data on a moving magnetic medium. It allows for simultaneously reading stored data from a cell on the magnetic medium and overriding it by writing new data to that same cell. This is accomplished by using timing impulses to select cells for reading and writing, with the reading gate impulse occurring just before the writing gate impulse. This provides time to determine what new data should be written based on the read data and other inputs. The document describes the technical details and diagrams of how this works.
This document provides a summary of GB780031 (A), which describes a process for manufacturing acid amide derivatives of azo-compounds. Specifically, it involves condensing an amine containing at least two reactive amino groups with a carboxylic acid halide from an azo compound, where the azo compound contains a carboxylic acid ester group next to the azo linkage. The starting materials used do not contain groups that impart water solubility. A variety of diamine and azo compounds are described that can be used in this process.
This document describes improvements to methods and apparatuses for filling large collapsible shipping containers. Specifically, it describes pressurizing the container before filling to expand it fully, then filling it while maintaining pressure. This ensures utilization of the container's full capacity. The document provides detailed descriptions and drawings of various apparatuses that can pressurize and fill the container through separate or same openings, including features like telescoping filling tubes and screw conveyors to direct filling material.
This document describes patent GB780026 (A) filed in 1957 regarding improvements to rotary pumps, compressors, and engines. It includes a rotor with blades that form conveyor chambers and an abutment slide that separates the suction and pressure sides. The blades curve forward in the direction of rotation to fully fill the chambers and prevent ejection of the medium. The abutment slide has a cylindrical packing part that follows the sharp blade tips for improved efficiency. The abutment slide is controlled via a crank to match the rotor profile for various applications including high speed operation.
This document describes GB780027 (A), which relates to a new group of compounds called 3-piperidyl ethers and thioethers. These compounds have desirable therapeutic properties, particularly oxytocic activity and selectivity of action upon the in situ uterus without undesirable side effects. The document provides the general chemical formula for these compounds and examples of their synthesis, including by reacting piperidinols with aralkyl halides. Therapeutic uses including preventing or treating postpartum hemorrhage are also described.
This document describes a 1957 British patent for an anti-skid control device for fluid pressure brakes used in aircraft. The device uses a rotary inertia element and valve system to sense wheel skidding and automatically reduce brake fluid pressure to prevent skidding, while maintaining braking force. It aims to maximize braking torque without skidding by varying the time to sense skid recovery based on wheel acceleration rates and controlling brake pressure buildup during recovery. The device was an improvement over prior anti-skid systems which would fully release the brakes until the wheel resumed non-slip speed, resulting in greater stopping distances.

Description of GB780017 (A)
COMPLETE SPECIFICATION
Improvements in or relating to methods of Providing Shoes with
Moulded Shoe Bottom Members
We, THE BRITISH UNITED SHOE MACHINERY
COMPANY LIMITED, of Union Works, Belgrave
Road, in the City of Leicester, a British Com- pany registered under
the Companies Acts 1862-1898, do hereby declare the invention (a
communication from United Shoe Machinery Corporation, of Flemington,
in the State of New Jersey, United States of America, a corporation
duly organised under the laws of the said State of New Jersey, and
having a place of business at 140, Federal Street,
Boston, Commonwealth of Massachusetts,
United States of America), for which we pray
that a patent may be granted to us, and the method by which it is to
be performed, to be particularly described in and by the following
statement:
This invention is concerned with improvements in or relating to
methods of providing shoes with moulded shoe bottom members, the term
" shoe " being used herein generically as including outer footwear
generally and also the article in the course of manufacture.
There will be hereinafter described one convenient method provided by
the invention and illustrative thereof, the illustrative method being
a method of moulding a shoe bottom member of plastic material on to
the bottom of a shoe presented bottom downwards.
Various methods of moulding rubber or like soles on to shoe bottoms
are well known and have been practised for a considerable time, but
these generally involve considerable expenditure in moulds as
individual moulds are required for right and left shoes and for
different sizes and shapes of sole. Moreover the application of
2. considerable pressure is 'generally required to cause the material to
fill the mould and enter into bonding engagement with the shoe bottom
and this necessitates the use of pressure applying apparatus which
again involves considerable expense.
It is one of the various objects of the invention to provide an
improved method of moulding shoe bottom members on to shoe bottoms
wherein the need for the use of a large number of expensive moulds is
obviated or at least largely reduced, and wherein the need for the
application of substantial pressure is eliminated or at least
substantially so.
With the above object particularly in mind the illustrative method,
hereinafter described, comprises taking a shoe which presents a wall
member projecting downward below the bottom of the shoe around the
margin thereof, holding the lower edge of the wall member in
substantially fluid-tight engagement with a surface of a moulding
member which closes the cavity peripherally defined by the wall member
and bounded on the side opposite to the moulding member by the shoe
bottom, filling said cavity with dispersion of resin partides heating
said dispersion to solidify it and to bond the solidified dispersion
to the s,hoe bottom and to the wall member to form with said wall
member a moulded shoe bottom member firmly adherent to the shoe, and
finally removing said shoe and adherent shoe bottom member from
engagement with the said surface.
The said dispersion is, preferably a fluid mixture of a consistency
suitable for extrusion of resin particles in a liquid plastidser
having no substantial solvent action on the resin when cool but
capable of combining with the resin when heated to form a solidified
mass. When solidified the dispersion forms a plastic shoe bottom
member adhering firmly to the shoe bottom and, depending on the nature
of the wall member, adhering firmly to, or being integrated with the
wall member. The wall member serves the dual purpose of providing an
accurately placed retaining wall and of spacing the closing surface of
the moulding member from the bottorrrof the shoe to provide the cavity
for the moulding of the resin depression on the shoe bottom. It is
therefore unnecessary to provide for each of the various shoe sizes it
is desired to make side mould members arranged to close together to
grip the shoe between them. Moreover the wall member improves the
union between the sole and the shoe bot tom at the edge portions,
since the wall member may be secured to the shoe by stitching,
cementing, or otherwise to provide an extremely strong union.
In order that the above and others of the various objects of the
invention may become more clear, there will now be given, with
reference to the drawings which accompanied the provisional
specification, a detailed description of the illustrative method above
3. referred to. It is to be clearly understood however that the
illustrative method is selected for description merely by way of
exemplification of the invention and not by way of limitation thereof.
In the drawings:

Figure 9 is a fragmentary view in section of a shoe with tread surface
moulded thereon using a fourth wall member shape; and
Figure 10 is a fragmentary view in section of a shoe with tread
surface moulded thereon using a fifth wall member shape.
In practising the illustrative method a shoe 10 is mounted on a
suitable form such as a last 12 which will retain it in shape for-the
moulding of a shoe bottom member, hereinafter referred to as a sole,
thereon, For convenience in explanation, the process will be described
first in relation to the formation of a sole on a conventional flat
lasted shoe upper in which the urper has been shaped and
secured to an insole or sock lining 14. A wall
member 16 is permanently secured to the shoe
around the margin of the shoe bottom so as to
project downwardly below the shoe bottom
thus forming a cavity on the bottom of the
shoe. In the shoe shown in Figures 1, 2 and 3,
the wall member 16 is secured to the shoe upper around the margin of
the shoe bottom
4. by a cement bond 18, but stitching or other
known modes of fastening the wall member
may be used. Ordinarily, the wall member 16
will be at the periphery of the shoe bottom and
will define a full sole as shown in Figure 1
or, alternately, a forward portion of the sole
extending toeward from about the breast -line as shown in Figure 4.
This wall member
16 is preferably so constructed and formed as
to simulate a sole edge and may have an
exposed upper surface 20 which may be shaped to simulate stitched
grooved, or otherwise shaped conventional welting. For convenience in
making the necessary bend at the more
sharply curved portions of the shoe such as
at the toe and heel, notches-22 may be pr vided on the inner portions
of the wall mem
ber 16 at such portions. The ends 24 of the wall member 16 are brought
together in fluid
tight engagement just forward of the heel portion of the shoe cn the
inner edge. A fluid-tight joint is conveniently formed by arranging
that the ends of the wall member
form complementary angles, for example a V
shaped notch and a V-shaped projection which
are fitted together as shown in Figure 1.
The wall member may be formed of any strong, tough material such as
those normally used for welting which are capable, or may be treated
to be capable, of bonding strongly to Dlasticised resin. For example,
leather or vinyl welting material may be used. It is how- ever,
preferred to use a strip of plasticised resin similar to the
plasticised resin which is usted when solidified to form the shoe
bottom
member since in this combination the wall member and shoe bottom
member become an integral body and the greatest possible strength
is obtained.
The bottom of the shoe, in this case the
bottom of the insole or sock lining 14, may be coated or lightly
impregnated with a thin fluid, resinous material suitably an aqueous
dispersion of resin particles such as a resin latex. A suitable resin
latex is a 54.6 !. so!ids
polyvinyl chloride latex. Other aqueous dis
persions or latices of resins compatible with
the resin to be moulded on the shoe may be used. When the bottom
surface of the shoe
has been treated with the resinous material, it is dried if necessary
5. and is then ready for the moulding operation. This coating or irr.prw-
nating treatment is likely to give a very strong
bond between the shoe and a sole moulded thereon. It is to be
understood, however, that the treatment may under some conditions at
least be omitted.
A moulding member, shown as a moulding plate 26, (Figure 1) adapted
for cooperating with a shoe bottom 14 and with a wall member 16 for
forming a sole comprises a relatively thick body portion 28 having on
its upper side a moulding surface 30 whose contour is complementary to
the desired contour of the tread surface of the shoe. Since the
outline of the sole member is defined by the wall member 16 attached
to the shoe 10, the contoured plate is usable for moulding a range of
sizes of shoe soles. The sole moulding plate 26 may be of metal or
suitable material capable of being formed to the desired shape and of
withstanding heat and transmitting heat to fluid material in contact
therewith.
The shoe 10 is disposed on the moulding plate 26 with the wall member
16 on the bottom of the shoe 10 held forXexamPle by suitable pad
members 32 (see Figures 2 and 3) in substantially fluid-tight
engagement with the contoured surface 30 of the moulding plate 26.
Peripherally defined by the wall member 16 and bounded on the side
opposite the moulding member 30 by the bottom face of the insole or
sock lining 14 a cavity 34 is provided for the formation of a shoe
bottom member of suitable thickness. Preferably, the distance between
the bottom face of the insole or sock lining 14 and the upper surface
30 of the moulding plate 26 should not be less than '/,, of an inch. A
fluid dispersion of resin particles in a liquid plasticiser is
injected into the cavity either through a temporary opening in the
wall member 16. through a suitable inlet opening 36 in the moulding
plate 26, or through a temporary opening in the insole or sock lining
14. A sufficient quantity of the resin dispersion is introduced to
fill the cavity defined by the bottom of the insole or sock lining 14,
the wall member 16 and the surface 30 of the moulding plate 26 when
the shoe is positioned thereon as shown in Figure 2.
Resin dispersions employed in practising the illustrative method are
fluid to nasty mixtures of from 30% to 70% of thermoplastic resin
particles in from 70ova to 30 /O of a liquid plasticiser having no
substantial solvent action on the resin when cool, but capable of
combining with the resin particles when the dispersion is heated to
form a uniferm solidified mass of plasticised resin. The relative
propertions of resin and plasticiser selected will depend on the
physical troDerties desired in the final tread surface. For example,
high relative proportions of plasticiser will give a softer more
rubbery sole than lower relative proportions within the range.
6. The particle size of the dispersed resin may vary within relatively
wide limits. However, particles of from 275 to 325 microns may be
found satisfactory.
Resin dispersions, fluid or pasty at room temperature, which may be
particularly satisfactory include: a dispersion of particles of a
copolymer of vinyl chloride and vinyl acetate containing from 85 (;;
to 88 '0 of vinyl chloride in a substantially equal quantity by weight
of dioctyl-phthalate; a dispersion of 50 parts of particles of a vinyl
chloride, vinyl acetate copolymer containing 85% to 88'to of vinyl
chloride in 45 parts of dioctyl-phthalate; and a dispersion of 50
parts of vinyl chloride, vinyl acetate copolymer, and 49 parts of an
ester type plasticiser which may be tricresyl phosphate, dibutyl
phthalate or dioctyl phthalate. Dispersions of other resins, including
polymethyl methacrylate and vinyl chloride-vinylidene chloride
copolymers in plasticisers in which they are dissolved or gelled when
heated, may be employed, provided the solidified resin body obtained
on heating the resin dispersion possesses the toughness, hardness and
resilience to render it suitable for use as a shoe sole.
It may be found desirable in certain dispersions at least to use a
stabiliser such as strontium naphthenate.
Limited amounts of fillers may be incorporated in the dispersion prior
to moulding.
Fillers which may be employed include fibres of copolymerised vinyl
chloride and vinyl acetate, sisal fibre, diatomaceous earth and clay.
Other fillers may be used. The percentage of fillers will depend on
the stiffness, strength, or other property desired. The dispersion may
also include any compatible dye or pigment or combination of these.
Where pigment is used it may first be ground into the plasticiser.
In practising Ithe illustrative method the shoe is, as aforesaid, held
with the wall memb-r 16 in substantially fluid-tight engagement with
the moulding plate 26 by any suitable pressure device such as the pad
32; and the assembly of shoe and moulding plate with resin dispersion
in the cavity between them is subject to heating to convert the resin
dispersion to solid condition. The heating may be effected in various
ways such as placing the assembly on a hot plate and maintaining it
there for a period of from 5 to 20 minutes after the resin dispersion
has reached a sufficigently thigh temperature to cause it to solidify,
e.g., a temperature of from 270 to 325 with the vinyl chloride-vinyl
acetate copolymer dispersions referred' to above. Other heating means
may be employed including heating cartridges provided in the moulding
plate such as those shown at 35 (Figure 4), placing the entire
assembly in a heating chamber, or the application of a high frequency
electric field.
After the heat treatment the pad member 32 is disengaged from the shoe
7. and the shoe and adherent sole are removed from the moulding plate.
The edges of the shoe sole 38 thus formed present the appearance of a
shoe having a conventional sole and moreover the shoe is expected to
offer cxceptional resistance to separation of the shoe sole 38 from
the upper by reason of the firm union between the wall member 16 and
thy upper 10 and the strong bond between, or integration of, the wall
member 16 and the sole 38.
In operating on shoes of the flat lasted type, the wall member 16 is
secured to the periphery of the bottom portion of the shoe 10,
preferably by cementing using conventional sole attaching cements.
If it is desired to attach a heel by conventional methods of heel
attaching, a wall member 16I having an exposed upper surface 202 may
extend only part way around the periphery of the bottom portion of a
shoe 101 (see
Figures 4, 5 and 6) for example from approximately the heel breast
line on one side to the heel breast line on the other. With this
arrangement a modified moulding plate 26I is used which is provided
with a step 42 against which the ends 44 of a wall member 16I are
abutted to enclose a cavity between the step 42, the contoured surface
30I of the moulding plate 26t, the wall member 16t and the bottom 141
of the shoe 10I. Resin paste dispersion is introduced into this
enclosed space 34' and solidified by the same procedure as referred to
above in connection with the formation of a sole member over the
entire surface of the shoe bottom. As shown in Figure 6 a special heel
46 is attached to a-shoe 10' having a partial moulded sole 38', a
portion 48 of the heel extending as far as desired over the rearward
end 40 of the sole 38I.
If desired fibrous material inserts may be secured to the bottom of
the insole or sock lining in such a manner that they will be enclosed
within the body of resin moulded on to the bottom of the shoe in
spaced relation to the tread surface. These inserts may be
incorporated by attaching them by any convenient means such as tacks,
nails or adhesive to the bottom surface of the insole of a welt type
shoe or the sock lining of a slip lasted shoe and carrying out
moulding operations as described above.
A variety of different wall members and methods of attaching them to
the shoe may be employed.
Figure 7 shows a wall member 16II having a cross-section particularly
suited for use with pre-welted shoes 1OTI as illustrated, but also
useful with normal welt type shoes. As shown, the wall member 16"
includes an outer portion 50 which provides the sole edge in the fini
shed shoe, a bottom portion which will be flush with the bottom
surface 52 of the sole member 38" to be formed, an inner edge portion
54 which joins with or bonds to the sole member 38Il and a top surface
8. 20" which may simulate
the upper surface of welting. A flexible lip
member 56 extends inwardly at the upper por
tion of the wall member 161t and has a channel
formed therein to receive stitches 58 to hold
the wall member 16tut to the shoe upper 10'I.
This type of wall member 16II is stitched to
the edge of the upper in a prewelt shoe or may be stitched to the rib
of a Goodyear type shoe (not shown). The shoe upper 10Il on a last
121I and with the wall member- 16" secured thereto is placed on a
contoured moulding plate 26 with the wall member 16" pressed in
sealing engagement with the surface 30 of the contoured plate 26. With
this construction and particularly with pre-welt shoes it is
preferable to employ a holddown for the wall member 1BI to insure that
the wall member is held flat against the contoured plate.
The moulding operation is then proceeded with as hereinbefore
described to provide a structure such as shown in Figure 7.
Figure 8 illustrates a wall member 16irk having a cross section
particularly adapted for use with slip lasted shoes. The wall member
16m comprises a body portion having a bottom surface 60 which will be
flush with the bottom surface of the finished sole 38it, an inner edge
portion 64 for union with the main body of the shoe sole 38III and an
edge portion 62 to provide an edge surface for the shoe sole. The
upper portion of the wall member provides a shoulder 66 on which rests
a lip 68 of the upper lOIII which is sewn to a sock lining 14III . The
wall member has an upwardly projecting flange 70 at its outer edge
which serves as an attaching portion through which stitches 72 are
inserted to bind the wall member 16irk to the shoe upper 1OTII and
sock lilt- ing. The moulding of a shoe sole on a shoe of this -
construction follows a procedure similar to that hereinbefore
described and illustrated in Figures 1, 2 and 3.
Figure 9 illustrates an alternative wall member 16IV which differs
from the wall member 16'it of Figure 8 in that the body portion of the
wall member extends outwardly beyond
the upwardly projecting flange 74 to provide an upper face 20ivy to
simulate a welt.
Figure 10 shows a wall member 16V comprising a body portion of which
one face 76 is intended to lie flush with the bottom surface of a shoe
sole 38v to be formed and another surface 78 is exposed at the outer
edge of the shoe sole 38V. This wall member 16V is provided with a
flexible side flange 80 having its exposed surface forming a
continuation of its edge portion 78. In this construction the flange
8C is secured by stitching 82 to the shoe upper 10V with the body
portion of the wall member 16V in inverted position; that is with the
9. flange 80 downward and the face of the wall member 16V which will form
the edge of the shoe sole positioned against the surface of the shoe
upper. Thereafter the flange 80 is bent to bring the wall member
16V to its final position with the flange 80
bent upon itself to give an appearance of a
platform cover at the edge of the shoe sole.
When the wall member 16V has been brought
to this relation, the formation of a shoe sole is carried out as in
the first described method.
What we claim is : -
