Actuator selection: External motor or internal servo motor?
There are key differences between traditional (external motor) and integrated (internal servo motor) actuators. Each technology offers performance advantages depending on the application type and requirements. Knowing how to compare the two will help engineers design machines that meet their requirements.

Silicon Carbide Machining from Insaco
"Silicon Carbide, excellent for high-temperature applications."
Silicon Carbide is industrially produced by sintering, reaction bonding, crystal growth, and chemical vapor deposition (CVD). It is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Different grades/forms of silicon carbide offer high thermal and some electrical conductivity well beyond other ceramic materials. Call Scott Mittl, Sales Engineer at Insaco, if you have specific questions (215) 536-3500.

U.S. scientists make matter and antimatter from light
Scientists studying particle collisions at the Relativistic Heavy Ion Collider, a U.S. Department of Energy facility for nuclear physics research, have produced definitive evidence that pairs of electrons and positrons -- particles of matter and antimatter -- can be created directly by colliding very energetic photons, which are quantum "packets" of light. Einstein would be proud.

Morphing Audi Skysphere concept: Variable wheelbase for cruising or sporty drive
Easily one of the coolest concept cars this year, the all-electric two-door Audi Skysphere has a lot of tricks up its sleeve. It's a low prowling sportscar in Sports mode and raises up and lengthens by almost 10 in. when autonomous Grand Touring is selected -- and the steering wheel and pedals disappear too. If this is the future, it's full of surprising design tech.

Expanded enclosure A/C inventory
Seifert Systems has completed their warehouse expansion, significantly increasing the types and quantity of enclosure air conditioners available. Air conditioners with popular cooling capacities within 1,000 to 21,000 BTU/hr are in stock and ready to ship. Among these are the Progressive, filterless SlimLine, and Compact Series of enclosure air conditioners as well as thermoelectric coolers. Seifert enclosure air conditioners come with a two-year warranty. SlimLine units are only 4.5 in. deep, and many Progressive units share the same size footprint for easier planning when needed for more than one application.

SPIROL introduces Press-N-Lok Pin for plastic housings
The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs as compared to screws and adhesives -- just Press-N-Lok™!

50 years ago: Apollo 15 first lunar rover drive and the Genesis Rock
The fourth Moon landing mission began on July 26, 1971, with the launch of Apollo 15. Astronauts David R. Scott and James B. Irwin went to the surface, while Alfred M. Worden remained in orbit aboard the Command Module Endeavour. Scott and Irwin conducted four spacewalks, including three excursions using the Lunar Roving Vehicle for the first time, deployed experiments, and collected 170 lb of rock and soil samples to return to scientists on Earth.

New revolutionary Revolox™ self-locking ring for high RPM
The revolutionary Revolox Self-Locking Retaining Ring from Smalley. Secure and easy locking for your high-speed rotational needs. The "dimple and slot" design prevents ring expansion, safely securing your application at high RPM. This makes it possible to operate at higher speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading. The Revolox self-locking ring enables engineers to cost-effectively design for high RPM requirements and with ease of assembly for high-volume applications.
