50 Years Ago: Charlie Brown and Snoopy in Lunar Orbit (Apollo 10 -- Part 2)
The Apollo 10 mission was a dress rehearsal for the Moon landing. Once in lunar orbit, the Lunar Module "Snoopy" would descend to about 50,000 ft above the Moon's surface and then travel hundreds of miles from the Command and Service Module "Charlie Brown," simulating a liftoff from the Moon. Then it would attempt a rendezvous and docking with the Command and Service Module. [Countdown Series: 50th anniversary of Apollo 11]

Solving keyhole formation may be key to better metal 3D printing
Additive manufacturing's promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, particularly in metal 3D printing, which can lead to cracks and other failures. These pockets, which can form potentially damaging "keyholes," can undermine consistency in manufacturing and create a hidden danger built into finished products.

Top Product: Alternative to traditional drive systems
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99 percent efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen's RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.

Top Tech Tip: Choosing between brush and brushless DC motors -- What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

Small internal mix spray nozzles coat, cool, treat, paint
EXAIR's new 1/8 NPT small internal mix spray nozzles atomize fluids up to 28 gal/hr. Internal mix atomizing nozzles mix the liquid and air inside the cap and produce the finest atomization. They can be used on liquids with a viscosity up to 300 centipoise. Small internal mix nozzles are available in narrow angle round pattern, wide angle round pattern, and flat fan pattern and are used to coat parts in containers, cool laminates, or apply paint and lubricant. They combine liquid and compressed air to create a coating of liquid that can be easily adjusted to meet the needs of your application.

Image - High-deflection thermal gap filler
High-deflection thermal gap filler
Laird Performance Materials has developed Tflex HD80000, a high-deflection thermal gap filler combining 6 W/mK thermal conductivity with superior pressure versus deflection characteristics. The combination allows minimal stress on sensitive components while also yielding low thermal resistance. As a result, less mechanical and thermal stresses are experienced in devices designed for telecom, information technology, consumer, industrial, aerospace, and military markets. Gap fillers bridge the interface between hot components and a chassis or heat sink assembly to increase the overall heat transfer from the system.

Compressed air leak detection you can see!
Fluke Sonic Industrial Imager

According to the Compressed Air and Gas Institute, the average compressed air system loses 30 percent of its air through leaks, but locating those leaks has been a time-consuming and tedious process. The new Fluke ii900 Sonic Industrial Imager enables maintenance teams to quickly -- and visually -- pinpoint the location of compressed air, gas, and vacuum system leaks even during peak production periods. Leaks can be detected in a matter of minutes. With minimal training, technicians can identify compressed air leaks considerably faster than using traditional diagnostic methods. Now checking for air leaks can be performed during a typical maintenance routine.
