| Protecting Fluid Circuits with Edge Welded Bellows Use edge welded metal bellows to compensate for expanding fluids and to prevent leaks that could damage equipment in many fluid-power and fluid-handling applications. BellowsTech edge welded bellows are superior to alternative methods because they are able to maintain proper flow during normal operation and expand and contract to compensate for volumetric changes of the liquid or gas that could otherwise result in blown seals, leaks, broken sensors and premature wear and tear.

| New Standards for Precision in Micro Motion MICROMO announces the new high precision IER3 optical encoders from FAULHABER. The new encoders deliver 2 channel quadrature signals plus an additional index signal, and can be combined with CXR and CR small DC motors, and BX4 and BP4 brushless DC servo motors from FAULHABER. The optical measuring principle gives the IER3 a strong edge in terms of accuracy and signal quality -- compared to encoders with other measuring principles.

| Titanium-gold alloy 4x harder than most steels Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant, and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.

| Wings: Next-gen Cessna turboprop features jet-engine tech and 3D-printed engine parts Textron Aviation just unveiled a new business aircraft powered by a propeller engine that features many of the comforts of a private jet, but at an entry-level price. The plane, called the Cessna Denali, will have the largest cabin in its class -- seating up to eight people -- and an engine powerful and efficient enough to reach Chicago from Los Angeles or Miami from New York. GE Reports takes a look at the plane's jet-engine technology and 3D-printed engine parts.

| Engineer's Toolbox: NASA completes first round of composite shell buckling tests with a bang How do you learn how to build stronger, lighter rockets and spacecraft structures? You come up with a totally new design, use an innovative material, build the rocket part, and then break it. NASA successfully completed the first series of high-tech composite tests in late spring as a large cylindrical barrel was tested to failure under extreme compressive loads of almost 900,000 lb, all in the name of building lighter, stronger primary structures for future launch vehicles.

| Why plastic bearings outperform metal Plastic bearings cost and weigh less than their metal counterparts. And they often run longer in harsh environments and under adverse conditions. Plain bearings molded of plastic are often an economical replacement for needle, ball, and plain metal bearings. To a certain extent, though, plastic bearings face an uphill battle for respect among the engineering community.

| Thermal Solutions: Lightweight zipper-fin heat sinks New zipper-fin heat sinks from Advanced Thermal Solutions (ATS) are protecting thousands of components from the dangers of excess heat at a lower cost than other high-fin-density heat-sink types. Zipper fins are machined from thin sheet metal, typically aluminum or copper, and are formed into custom shapes. Zipper-fin sinks can be designed with integral ducts to contain and optimize cooling airflow for LEDs as well as hot components in the telecom, datacom, military, and embedded electronics industries.

| Motion: Compact linear positioning stage driven by ultrasonic piezo linear motor Ultrasonic piezomotors from Physik Instrumente are small and provide motion with high resolution, as well as an extremely wide dynamic range from microns/second to hundreds of millimeters/second. A significant advantage over magnetic drive technologies (such as voice coils, brushless, and 3-phase motors) is the self-locking principle: Once the motor reaches a target position, it acts like a ceramic brake and locks the platform into place, providing extreme long-term stability at zero driving current and heat generation.

| Countering the reappearance of old-school views on product design In the early 1980s, a product design methodology called Design for Assembly (DFA) began to gain popularity. In the past 10 years, there has been a significant resurgence in a different design philosophy -- a very old and outdated one -- that is skewing the productivity gains companies achieved through DFA. Using real-world examples, Boothroyd Dewhurst's Brian Rapoza describes how to -- and how not to -- cut costs during part redesigns.

| Is your company in a bad mood? 11 signs and what to do about it The signs aren't always overt. People aren't biting each other's heads off or glaring sullenly across the conference table. Instead, it feels like everyone is just ... coasting. They're not cage-rattlers and idea-sharers; they're "yes men" and passive compliers. That's "bad mood" in workplace parlance. And Michael Houlihan says that apathetic clock-punchers are the creations of a culture that's set up to squelch their inner entrepreneur.

Guy turns floppy drives, scanners, etc. into orchestra Polish university student Pawel Zadrozniak, who admits he has extra time on his hands, makes impressive music from the mundane sounds of things like stepper motors running magnetic heads on floppy drives or flatbed scanners moving back and forth. Learn about his unique approach to creating his own full-blown orchestra (called the "Floppotron"), and enjoy music from "Star Wars," "Hawaii Five-O," Nirvana, and "Game of Thrones" along the way.
