Advances in Phased Array Weld Inspection Scan Plan DesignsOlympus IMS
The compound S-scan improves on traditional phased array weld inspection scan plan strategies by combining the S-scan and E-scan inspections as defined in ASME V, Article I into a single acquisition group providing more inspection coverage of the weld volume and heat affected zone. The compound S-scan improves the range and performance of existing phased array 1D pulse-echo probes, wedges, and instrumentation via new functionality in focal law calculators that are commercially available today from Olympus and other manufacturers.
Additional benefits of the compound S-scan inspection include ability to use pre-defined configurations over a larger range of weld bevels and thicknesses, enforcement of fewer essential variables in the inspection work procedure, and a more efficient work flow for phased array inspection setup, calibration, acquisition, and data analysis IAW ASME V, Article 4, Phased Array Mandatory Appendixes IV and V.

This document provides an overview of non-destructive testing (NDT) methods. It describes six common NDT methods - visual inspection, liquid penetrant inspection, magnetic particle inspection, radiography, eddy current testing, and ultrasonic inspection. For each method it explains the basic principles, advantages, limitations and applications for inspecting materials and detecting flaws without causing damage. NDT methods are used at various stages of production and service to evaluate integrity and detect issues in a wide range of industries.
1. Firearms analysis examines guns, bullets, and cartridge casings to determine if a specific gun was used in a crime. Microscopic marks left on bullets and casings when fired provide unique "fingerprints" that can identify the weapon used.
2. Gun barrels leave distinct striation marks on bullets that pass through them. Comparing test-fired bullets to evidence bullets under a microscope can match bullets to the firearm from which they were fired.
3. Other toolmarks left on cartridge casings, such as firing pin impressions and ejector marks, also provide identifying patterns that link spent casings to a particular firearm. The combination of these factors allows forensic experts to determine if a gun was used in
Non-destructive testing (NDT) refers to a group of analysis techniques used to evaluate materials, components, or systems without causing damage. Common NDT methods include liquid penetrant testing, magnetic particle testing, and ultrasonic testing. Liquid penetrant testing uses a dye that is drawn into surface-breaking flaws by capillary action and visualized. Magnetic particle testing magnetizes a part and uses iron particles to indicate areas of magnetic flux leakage from subsurface flaws. Ultrasonic testing uses high frequency sound waves that reflect off internal flaws and interfaces, with the reflections analyzed to detect and characterize imperfections.
The document discusses two non-destructive testing methods: liquid penetrant testing and magnetic particle testing. Liquid penetrant testing uses liquid that is drawn into surface cracks by capillarity, then a developer reveals the flaws. The process involves surface cleaning, penetrant application, dwell time, developer application and inspection. Magnetic particle testing uses magnetism to detect subsurface flaws in ferromagnetic materials. Iron particles are attracted to cracks when the part is magnetized. The process involves demagnetization, magnetization, particle application and inspection under lighting. Both are widely used to inspect parts for cracks and defects.
Needle-free injection systems use jet pressure to inject medications into patients without a conventional needle. The drug is forced through a specially designed nozzle at high speed, penetrating the skin within 300 milliseconds. This allows for faster dispersion of the drug into the epidermis compared to standard injections. Needle-free injections provide benefits like painless administration, reduced medical waste, and protection of healthcare workers from needlestick injuries. However, they may damage some fragile drug molecules on repeated use. Major brands offering needle-free injection technology include Injex, Pharmajet, and Antares Pharma.

The document discusses two methods for developing latent fingerprints through alternative light sources:
1) Post-treatment of developed fingerprints with luminescent powders or dyes that fluoresce under laser light, intensifying the ridge detail. Commonly used materials include acridine orange, rhodamine B, and lanthanide complexes.
2) Developing fingerprints chemically by applying reagents that react with amino acids in sweat to form fluorescent compounds, such as ninhydrin forming Ruhemann's Purple or fluorescein forming luminescent derivatives. Zinc chloride treatment improves ninhydrin results and some lanthanide complexes provide longer fluorescence.
Hairs and fibers are important forms of trace evidence that can provide clues in forensic investigations. Hair has a cuticle, cortex, and sometimes a medulla, and characteristics like these can be used to identify a sample's origin. Fiber analysis examines properties such as the fiber's structure, color, and chemical composition to determine its type (natural or synthetic) and match it to a potential source. Due to their tendency to shed easily, fibers are commonly found as trace evidence and can link a suspect to a crime scene or victim.

Devastating grain dust explosions have been recorded for decades as the risk of flour dust ignition is so high. Without adequate controls and safety measures, grain flour explosions have been known to level entire milling facilities and take lives. While mill owners are making the effort to comply with DSEAR and ATEX regulations to ensure their staffs’ safety, the execution of preventive measures has not always been correct. Many milling facilities share common problems when it comes to the installation of protective equipment. In some cases, they inadvertently exclude “fail-safes” where necessary.
This document discusses grain dust explosions, their causes, and how to prevent them. Grain dust explosions can occur when there is a dust cloud at a particular concentration, a minor spark, and a source of oxygen. Sparks can originate from metal-to-metal contact, direct flames, batteries, grain spoilage inside silos, maintenance work, lighting, and electric panels. Regular safety checks of equipment like elevators, conveyors, tunnels, and dust filters can find and address potential spark sources to avoid explosions. Education about dust explosion risks and precautions is important for plant staff.
Development of a Procedure for Making Inspection Plans for Corroding Oil and ...Christine Berner

Another engineering area highly dependent upon a well-defined Technical Data Package (TDP) is the creation of in-process inspection plans and manufacturing process plans.
DISCUS Desktop enables you to take a TDP and quickly create a consolidated master list of requirements (i.e., the Bill of Characteristics) for the finished part. The DISCUS Planner add-on module adds rich functionality to enable you to assign characteristics to operations, create in-process characteristics for operations, and develop operation-specific process illustrations. DISCUS Planner operates as follows:
You start using DISCUS in the same fashion as used for ballooning of the final part drawing – that is, opening the drawing, dropping balloons, snapping rectangles, etc.
DISCUS Planner adds user interface elements to manage characteristics for each operation in the routing. For example, DISCUS Planner adds a panel for the part routing, operation details, work instructions, etc.
You then assign characteristics to specific operations, even changing the characteristic requirements at a specific operation. As needed, you may create in-process characteristics for an operation that don’t appear on the final drawing. You can create operation-specific illustrations of the ballooned part.
When you're done ballooning, you can export ballooned drawings and inspection characteristics specific to each operation. In addition, if you’re using DISCUS Planner for process planning, you can export the entire package – work instructions, process illustrations, and inspection characteristics – to a richly formatted process plan.
The primary output from DISCUS Planner is a structured and fully completed set of manufacturing planning documentation. This includes a summary routing – and for each operation – the work instructions, inspection sheets, and process illustrations. In addition to these primary features, DISCUS Planner automatically generates an operations analysis for the user to indicate characteristics where-used and “delta” values by operation.

Bearing Temperature Sensors
The WDB, MDB & ADB Series bearing temperature sensors are designed to
screw directly into an existing grease zerk fitting on a bearing housing. Each
sensor is fitted with a grease nipple to allow lubrication of the bearing without
the need for removal of the sensor. Most series are available with either a PTC
thermistor with various factory set trip points, or a NTC thermistor with a user
adjustable trip point, or as a Pt100 RTD version.
Speed Switches
Monitors rotating machinery for dangerous underspeed conditions. An inductive
sensing device located in the nose of the enclosure will detect a metal target. Set
to the normal machine RPM, 4B Speedswitches provide alarm and shutdown
signals underspeed and stopped motion.

more reliable monitoring.
Inductive Sensors
4B inductive proximity sensors are designed to detect shaft speed, shaft position,
gate position, or object presence. No contact is made between the sensor and
the target being monitored. Sensors will detect a
ferrous object at 12mm and a non-ferrous metal
object at a distance of 8mm.
*Can be used with the
Whirligig universal shaft
sensor mount.

DUST EXPLOSION
PREVENTION
It is well known that transporting certain dry dusty materials, such as grain, can
create explosive atmospheres.
Five conditions, known as the “Dust Explosion Pentagon”, have to exist in order
for the explosive state to occur. First, there needs to be a high concentration of
dust (fuel), followed by an ignition source (heat) and oxygen (oxidizer). If all of these
appear in a confined space with dispersion, an explosion can occur.
The most common ignition sources on bucket elevators and conveyors have long
been identified as over-heated bearings, misaligned belts and belts that are slipping.

MISALIGNMENT
SENSORS
CBS2
Bulldog
The CBS2 is an electro-mechanical system to detect
the misalignment of a belt conveyor. Two outputs
are given at 15 and 30 degrees which can be used
as alarm and stop signals respectively. Works in
conjunction with a CBS2 Elite control unit. The
sensors are normally installed in pairs, one on either
side of the belt, and up to 4 sensors per CBS2 Elite
control unit.
The Pullswitch is a failsafe taut wire emergency
pull cord stop switch for open conveyors.
PVC coated steel pull wires and pigtails connect
between the switches to provide easy installation
and continuous emergency stop access along the
length of the entire conveyor. Pullswitches can be
installed at 50m intervals, reducing overall system
cost. Quick location of a tripped switch is provided
by a standard reflector or optional flag marker, and
the tripped signal can be wired back to an indicator
panel, 4B controller or PTC.
The Bulldog alignment and rip detection switch is
an electro-mechanical system designed to detect
dangerous belt misalignment and belt tear damage
on open belt conveyors. The switch will detect
horizontal misalignment of belts when contact is made
with the roller; the roller arm will be forced to pivot
by the belt activating a switch at 15º to trigger an
alarm, and 30º to trigger a shut down. The sensors
are usually installed in pairs on opposite sides of the
belt. A flexible wire is set below the running conveyor
belt attached by a rare earth magnet at each end. If
the belt is ripped or damaged the wire is pulled away
releasing the magnet connection which in turn will
activate a switch to trigger an alarm or shut down.

BEARING TEMPERATURE SENSORS
WDB8 MDB WDB7 LUG STYLE
The WDB7 series is a lug style NTC, PTC,
Pt100 thermistor model for continuous
surface temperature monitoring and has
been designed to bolt directly onto a
bearing housing, motor, gearbox, or machine
casing. The mounting hole is 8mm from
the factory, but can be drilled up to 13mm
if needed. The sensor can be connected to
a PLC or to a hazard monitoring system,
such as 4B’s T500 Hotbus Elite, Watchdog
Elite, or T400 Elite. The connections are
not polarity sensitive therefore special
connections requirements are eliminated.
The WDB8 series is a range of bearing
temperature sensors designed to screw
directly into an existing 1/4" BSP grease
zerk fitting on a bearing housing. Each
sensor is fitted with a grease nipple to
allow lubrication of the bearing without the
need for removal of the sensor. The WDB
Series is available with either a PTC
thermistor with various factory set trip
points or an NTC thermistor with a user
adjustable trip point.
ADB
The ADB series have been designed to
allow the depth of the sensor to be
adjustable depending on your application.
Three standard versions are available with
probe lengths of 50, 100 and 200mm (other
lengths available for special order). The
sensors screw directly into a bearing
housing through the existing grease zerk
thread. Each sensor is fitted with a grease
zerk to allow lubrication of the bearing
without the need for removal of the sensor.
The ADB style sensors are available with a
standard NTC thermistor for 4B’s Hotbus
and Watchdog systems, or a 4-wire Pt100 -
RTD type for PLC and DCS systems.
ADB8 WDB8 MDB8 WDB7 LUG STYLE
The MDB series is a range of bearing
sensors manufactured to screw directly
into a bearing housing through the existing
1/4" BSP threaded grease zerk (can be
installed in 1/8" NPT grease zerk fitting
with an adapter). Each sensor is fitted with
a grease zerk to allow lubrication of the
bearing without the need for removal of
the sensor. The sensor is fitted with a M12
connector for use with a separately supplied
cable and socket assembly which can be
connected directly to a PLC or to a hazard
monitoring system, such as 4B’s T500
Hotbus Elite, Watchdog Elite, or T400 Elite.
The connections are not polarity sensitive
therefore special connection requirements
are eliminated.

ADB Bearing
Sensor Tester
The ADB Sensor Tester has
been designed to test 4B adjustable depth
bearing (ADB) temperature sensors in the field.
This hand held test unit features an integrated heating block
specifically designed to have a 4B ADB sensor directly
inserted. With integral controls and temperature display, the
unit heats the sensor to the desired trip point, and allows quick
and easy real life testing of the sensor and temperature
monitoring system.
During planned maintenance or periodic testing, the ADB
Sensor Tester can be used as a diagnostic tool to verify the
alarm and shutdown sequences of the control unit are
functioning as expected. To test, the heater block should be
set above the control units alarm operating temperature.
Remove the ADB bearing sensor probe from the housing and
insert it into the heater block. As the heater block reaches the
alarm temperature, the ADB sensor will relay this data to the
control unit, allowing you to verify that the alarm and shutdown
sequences run as expected.

switch is used to detect high / low
levels of bulk granular solids in
bins, tanks and silos. It can also
be used to detect plug conditions
in spouts, where long life and
failsafe detection is required.
Utilizing a unique stepper motor
drive, the RLI “Shaker” rotates
clockwise, then counter-clockwise
and then shakes to shed any
excess material build-up. If the
paddle rotation is impeded at any
time by the bulk material then the
electronic circuit provides a signal
for level indication or control.

4B offers an array of tools and services to support you and your
products. The 4B Tech Team can answer your installation and operating
questions, and provide on-site inspection, testing or commissioning
services for our products. 4B has developed testing tools to easily check
our sensors in the field during routine maintenance. We also have a
selection of tools available to help with the installation of our products.
The 4B high power WDA reluctance sensor will
detect a moving ferrous object up to 4" away. It is
not affected by dust or material build up. It can
be used as a slack/broken chain detector when
installed as shown below. The sensor has an
adjustable sensing range (1" – 4") and an LED
helps with field adjustment.
Using the mounting block supplied, cut a 4” diameter
hole in the sheet metal and position the mounting block so that the sensor
is centered on this hole. Alternatively, the sensor and mount can be
installed on a stainless steel plate without drilling a hole for the sensor. In
this case, the sensor will not be affected because the sensing field can
pass through the stainless steel plate.
WARNING - Make sure that there is no ferrous steel
(such as the machineʼs frame) within the sensing field.

Option 1
Sensor Detecting Bolt Installed on the Paddle
Under normal running conditions, the target bolt passes through the sensor’s field
and a pulse is sent to the speed relay. If the chain becomes slack, the target bolt
will drop below the field and the pulses will stop, causing the relay contact to
change state.
Option 2
Sensor Detecting Steel Flight
Under normal running conditions, the steel flight passes through the sensor’s field
and a pulse is sent to the speed relay. If the chain becomes slack, the steel flight

Option 3
Sensor Waiting to Detect Steel Flight
Under normal running conditions, the steel flight is out of the sensor’s field, so no
pulses are sent to the speed relay. If the chain becomes slack, the steel flight
comes into the sensor’s field and a pulse is sent to the speed relay, causing it to
change state.
