Play it safe
It's no secret that welding can be dangerous work if proper safety
procedures aren't followed. In the worst cases, safety lapses can lead
to disasters like the June 2006 explosion at a Mississippi oil refinery,
sparked by welding in the presence of flammable gasses. The U.S.
Chemical Safety and Hazard Investigation Board (CSB) just released a new
safety video explaining the accident that killed three and injured a
fourth. The free 9-min video, titled "Death
in the Oilfield,” includes 3D computer animation of the events
leading up to the explosion.
Although not all welding takes place in such potentially hazardous
environments, the video is a good reminder to double-check your safety
practices. Be safe out there!

HVAC Fasteners Get the Green Light
J.T. Products’ Zip-Ez fasteners for H.V.A.C. insulation have made
the GreenSpec Directory. The Directory lists only the top five to ten
percent of environmentally preferable products. The fasteners are said
to save energy while attaching insulation to ducts, and may offer
additional LEED points toward a building’s “green” certification.

Fast Setting Epoxy Adhesive Has One to
One Mix Ratio
 Master Bond
EP24 is a new high performance two-component epoxy adhesive that sets in
10-15 minutes at room temperatures. Durable, tough EP24 has a convenient
one to one mix ratio weight or volume. Adhesion to similar and
dissimilar substrates is excellent. EP24 is resistant to many chemicals
and is a superior electrical insulator.

High-Tech Jobs Slowing but Still
Growing
For the fourth year in a row, the software, engineering, and tech
service industries have increased the number of available jobs. However,
high-tech manufacturing lost jobs in seven of its sectors – which
means only two sectors showed gains. But with an overall gain of 91,400
jobs last year, it’s hard to say for sure if the industry is bound to
suffer a setback anytime soon.

Adhesive-Delivery System
The ADS1 DynaFill adhesive delivery system eliminates the need to
manually fill adhesive tank hoppers and minimizes adhesive contamination
by reducing adhesive exposure to the environment. Gradually adding
adhesive to the tank hopper also stabilizes the heat in the system for
cleaner operation. The system integrates into, and is compatible with,
most adhesive-application equipment. The inlet cover fits directly on
the hotmelt unit’s adhesive tank hopper.
The self-contained system operates on 20 cfm at 50 psi and automatically
draws and transfers adhesive to the tank hopper when the level falls to
a preset minimum. Adhesive is drawn through a suction wand immersed in
the adhesive bin and delivered under positive pressure to the tank
hopper. A vibrator on the wand keeps the adhesive flowing freely. A
capacitive sensor immersed in the tank hopper senses when the adhesive
level is low and responds by transmitting a signal to draw adhesive
through the wand and transfer it to the hopper. The sensor shuts off the
flow when the tank hopper is full. The system feeds a hot-melt unit up
to 22 ft vertically and 100 ft horizontally.

Fast-Cure Adhesive Okay for Disposable Medical
Devices
Loctite 3974, a light-cure adhesive, bonds materials that expand at
different rates when heated. The single component acrylic cures quickly
to a 70 Shore A hardness under UV or visible light. Its 100% elongation
makes it a candidate for flexible components. It bonds glass,
thermoplastics, and metal assemblies that see extreme thermal cycling
and harsh environments and is ISO-10993 biologically tested for use in
disposable medical devices. The adhesive fluoresces under black light
for easy quality-control inspection and is available in a variety of
package sizes to accommodate manual to fully automated dispensing.

Threaded Inserts
SI threaded inserts let users install metal threads in plastics for
removal and re-attachment of access panels. The inserts can be installed
by ultrasonic heat staking or with a thermal press. They can also be
molded in during fabrication or pressed into molded or machined
holes.
The inserts come in brass, stainless steel, or aluminum in a range of
diameters and thread types. CAD models are available on the company's
website.

Four Methods of Flush Riveting
Talk about a blast from the past. This animated instructional video
was released in 1942 for the Lockheed Aircraft Corporation, produced by
none other than the Disney Studios. Take a peek at the four methods of
flush riveting (specifically designed to reduce drag on aircraft) and
consider this: this short film was the Disney Corporation’s first
attempt to show the effectiveness of animation in training videos.

Rev up your interdisciplinary design skills
What happens when a microcontroller turns on a power FET, sending a
current pulse to a motor coil that develops a magnetic field which turns
the rotor shaft, advancing a timing belt that drives a pair of nip rolls
suspended on bearings in a web-processing operation on a form, fill, and
seal machine installed on a potato chip line at a Frito Lay plant in
central California? And how can you be sure that the encoders, prox
sensors, and other feedback devices you plan to use will accurately see
and report every relevant motion, machine state, and process condition?
And will the signals get through the networks fast enough, without being
corrupted, giving the controllers time to execute their algorithms as
intended? It's a lot to think about, and it only scratches the surface
of what many engineers grapple with today. If you happen to be one of
them, then the place for you — where you can find answers and meet
others with similar concerns — is www.Mechatronic-Design.com.
