The document discusses problems with conventional sheetrock installation methods using nails and screws, which can fracture the gypsum or tear the face paper. It introduces the Pre-Set device, which limits the depth of nails and screws to maintain the three-point bond between the sheetrock's face paper, gypsum, and back paper. The Pre-Set provides benefits like minimizing gypsum fracture and face paper damage. It also allows for faster installation using nail guns and pneumatic tools modified to work with the Pre-Set. The Pre-Set provides a more uniform installation with advantages over conventional fasteners.
Galvanizing: The ultimate in fence protectionSophieBoothroyd
With over 160 years in galvanizing, Corbetts has the experience and expertise in supplying the fencing sector. Corbetts are perfectly set-up to galvanize your steel fence fabrication with specific capabilities, a 48-hour turnaround and a national collection and delivery service.
Temporary chain link fence is made up of chain link mesh panels weaved by hot dip galvanized steel wire, tubular welded frame, clamps and stable fencing block. All panels are hand made by traditional craft from beginning to end. Technical workers use tension bars and tension bands to wrap the tie wire tightly around the tubular frame. And then a self-supporting and modular temporary fencing system is formed.

Brass conduits protect wires and keep your home safePallega
You must install brass conduit fittings right to provide protection to home wires. Conduit works as a shield for wires. Even if local codes allow armored cable installation in a garage, basement, crawlspace, or attic, deploying conduit to protect wiring is recommended.

INTRODUCTION- Removable partial denture: the replacement of missing teeth and supporting tissues with a prosthesis designed to be removed by the wearer-GPT.
Cast partial denture is a type of partial denture comprising a cast metal framework with acrylic resin prosthetic teeth.
Traditional acrylic partial dentures are less durable, retentive, and stronger than cast partial dentures.

UV Channel Drilling in LDPE using an Excimer Laser and its Available WavelengthsDana Lee Church
This project paper shows the level of investigation used to discover the UV Excimer laser material interaction for channel drilling in varying thicknesses of LDPE using the TeoSys patented OEM Excimer laser.Although we are able to get +/- 200 microns depth of focus, this material posed other significant challenges as the LDPE exhibited anisotropic properties. The amount of anisotrophy is are related to the stress applied and the relaxations in the flow-induced crystallization process, which determine the amount of fibrillar nuclei available at the time of crystallization. Therefor, determining a viable recipe was, well, fun....!

How Glass Reinforcements Choice Can Effect Bow In Pultruded Parts. OC_Composites
Presentation by Kevin Spoo, Owens Corning Senior Research Associate, at CAMX 2015. This research highlights bow in pultruded parts, which is different from the dimensional changes caused by resin. The choice of glass fiber reinforcement can cause a stress differential, which can cause issues of bow through the cross-section of a pultruded part. In the experiment that was discussed, two types of glass reinforcements were fed into a pultrusion die with all other parameters of the system being equal.
2. The strength of sheetrock
relies on maintaining the
Three-Point Bond
of the components shown:
Sheetrock Structure
A - Face paper
B - Gypsum
C - Back Paper
Conventional Installation methods can’t accomplish this.
A. Face Paper
B. Gypsum
C. Back Paper
4. Typical Installation Problems (Cont’d)
Screws:
the face paper is cut
due to driving the screw
too deeply or is torn
from friction between
the paper and the
rotating screw head.
5. Typical Installation Problems (Cont’d)
Sharp edges on
rotating screws can
result in lacerated
fingers, resulting in
lost time.
6. Solution To Installation Problems
The shoulder on the Pre-Set limits nails & screws to a
constant depth, thereby limiting fracture of gypsum and
avoiding cut face paper.
A Small Innovation With Huge Implications
7. The Pre-Set Device
• Material:
Polycarbonate
• Properties:
• High impact strength
• Temperature range –
40F to 212F
• Good dielectric
strength
• Inexpensive
9. Pre-Set Nails
• Friction between the Pre-Set and the face paper draws
the paper down in a smooth arc, maintaining the
paper’s structural integrity.
• Pre-Set minimizes fracture of gypsum.
10. Pre-Set Screws
• Face paper is not damaged by overdriving because of
positive stop provided by Pre-Set.
• No cut fingers because Pre-Set is stationary while
screw is rotating.
11. Finishing
Pre-Sets provide a
1/16” recess of the
screw or nail head
below the surface of
the sheetrock to
ensure an adequate
depression to receive
joint compound.
1/16”
12. Temporary Positioning of Sheetrock
• Sheetrock may be
positioned using the
Pre-Set but not driving it
home.
• As such, it allows the
choice of relocating the
piece or driving the
screw to depth.
13. Changing the Industry Standard
• Hand installation of nails and screws is time-
consuming, therefore expensive.
• Pre-Sets provide a bridge to the future of sheetrock
installation by enabling the use of pneumatic nailers.
18. Time Considerations
• If a plain screw misses
the stud, the screw will
still advance through
the sheetrock.
• A Pre-Set screw will
stop advancing when
the shoulder contacts
the sheetrock.
• Driving a nail (3 strokes)
• Driving a screw
• Nail gun
4 Seconds
4 Seconds
1 Second
(Nail & screw times include
accessing them from a pouch
or apron.)
21. Summary
• A Perfect Fit For Screw-Nail Fasteners
• Maintain 3-point bond of sheetrock
• Screw & nail heads all recessed 1/16”
• Provide most uniform contact with studs
• Greater load bearing capacity
• Fastest installation
• Lowest labor cost
Advantage of Pre-Sets over conventional nails & screws:
