Unit Conversion Tool
Convert popular spring units such as force, or retaining ring thrust
capacities, into metric units with Smalley's new engineering tool. A
simple conversion tool allows for units to be converted such as mass and
weight, angular measurements, velocities, temperatures, pressures and
densities and more. Additional engineering tools allow engineers to
design custom wave springs and Spirolox® retaining rings. Custom
designs can be manufactured from .200" to 90". Smalley Steel Ring

Epoxy Adhesives Hold Their
Own
Advances in adhesive bonding have made it competitive with
high-performance traditional fasteners, such as the rows of rivets on
airplanes, as well as other kinds of bonding such as brazing and
welding. The use of adhesives could allow for lighter structures and
longer service lives in aerospace, marine, electronic, and automotive
uses, and can also improve the aesthetics of a product. In addition,
adhesive joints can avoid the effects of heat and stress that welding or
drilling holes can cause, which means designers may be able to cut back
on attachment strength requirements. On the factory floor, adhesive
bonding can also cut down on assembly costs, eliminate some steps from
the manufacturing process, and reduce the amount of training and skill
needed by workers. Using adhesives does, however, demand proper
knowledge of how best to store, dispense, apply, and cure the adhesives
and prepare the substrates.

Fastener Woes to Delay Flight of First
Boeing 787 Jets
Delivery of Boeing's much-anticipated 787 Dreamliner will be pushed
back once again due to problems with fasteners. Problems discovered
during a routine quality-control inspection will force the company to
replace thousands of fasteners that were improperly installed. This is
the second time Boeing has run into problems with fasteners. Since the
Dreamliner is made largely from carbon-fiber composites and machined
titanium castings, instead of conventional steel and aluminum, Boeing
had to come up with new types of fasteners to keep the plane together.
Problems first erupted two years ago when suppliers had trouble getting
enough of the specialized fasteners to assemble the first planes. The
first Dreamliner delivered to Boeing was thus held together by thousands
of temporary fasteners.

Gecko-like Glue Is Said to Be
Stickiest Yet
U.S. researchers have developed a dry glue designed to mimic the
adhesion of gecko feet that is three times as sticky as other
gecko-inspired adhesive products. A 1-inch square of the adhesive can
reportedly support the weight of a 220-pound man climbing up a vertical
surface. "It's the stickiest dry glue yet," says Liming Dai of the
University of Dayton, who authored an article on the glue in the journal
Science. The glue can easily be lifted and reapplied thanks to curly
strands of carbon that when lifted at an angle break the bond. One of
the glue's potential uses is to remove the need for soldering electrical
components, and since the glue is dry, it could be used at very low
temperatures, such as in space, where conventional glues lose
adhesion.

Latch Integrates Electronic Access
CONCORDVILLE, PA: The new Southco® R4-EM electronic rotary latch
combines robust rotary latch security and electronic access convenience
in a single integrated solution. Unlike a standard mechanical latch
linked with a separate solenoid actuator, the gear-motor drive in the
R4-EM delivers a better feel to latch actuation and is more efficient in
terms of lower power requirements and higher load capability. The
compact integrated latch design also makes the R4-EM easy to install,
operate, and maintain. The 2.56" x 2.72" x 0.75" (65 x 69 x 19mm)
housing requires minimal space and minimal protrusion inside the
compartment, and installs simply with just two bolts to keep
installation costs low. Its proven mechanical design and all-metal
construction provide excellent vandal resistance with long-term
durability and reliability. --- Southco

Quick Clamping Shaft Collars
MARLBOROUGH, MA: Ruland Manufacturing Company has introduced new
quick clamping shaft collars. The new collars do not mar the shaft, do
not require tools and are designed for quick adjustments. They are ideal
for light duty applications with frequent setup changes or adjustments
or where the need for tools is not practical. The quick clamping
collars are designed with a low profile clamping lever which makes them
suitable for rotating and stationary applications. Industries such as
printing and packaging, as well as others, can benefit from the use of
quick clamping collars to retain frequently changed items, such as rolls
of media, or for rapid and precise adjustments of guide rails or other
setup fixturing. The quick clamping collars are made from high quality
aluminum with an anodized finish which has the advantage of being
light-weight and having low inertia. The quick clamping shaft collars
are available with bore sizes from 5/16" to 1 1/2" in the inch series
and 8mm to 35mm in the metric series. --- Ruland Mfg. Co.
