Wavo: The New Spring in Town
Wavo are produced from round-section wire to provide higher loads while maintaining the accurate loading found in wave springs. As an alternative to Belleville Springs, the Wavo Wave Springs provide similar loads but with an accurate, predictable spring rate. Available from stock in 1/2" to 6” diameters. Free samples available. Customs can be manufactured from .165" to 120".

Unique phononic filter could revolutionize signal processing systems
A unique filtering technology that combines light and sound waves on a single chip is expected to better detect radar and communications frequencies. The radio frequency (RF) filters, which promise both high bandwidth and wide functional flexibility, would form the basis for spectrometers that would let users "see" energies placed in various frequency bands across a wide spectral range.

Ultra-low friction without oil additives
Researchers at Georgia Institute of Technology have developed a new process for treating metal surfaces that has the potential to improve efficiency in piston engines and a range of other equipment. The method improves the ability of metal surfaces to bond with oil, significantly reducing friction without special oil additives.

Wings:
NASA to test in-flight folding Spanwise Adaptive Wing concept

NASA is developing and validating a system that will allow part of an aircraft's wing to fold in flight. The aim is to test the feasibility of increasing efficiency through wing adaptation. The concept would permit the outboard portions of the wings to move to the optimal position during operation, which could potentially result in an increase in efficiency by reducing drag and increasing lift and performance.

Mike Likes: ABCs of gears and more
KHK USA takes you on a journey through the history and applications of gears in two information-packed free volumes called "The ABCs of Gears." Part A is aimed at beginners, while part B moves on to intermediate fare, such as types of gears and tooth forms, heat treatment, surface treatment, production methods, etc. Another mid-level text called "Introduction to Gears" and an in-depth "Gear Technical Reference" are also available, chock full of materials information and calculation examples and tables. Best of all, there is no registration for any of these valuable no-cost PDF resources.

Engineer's Toolbox:
Microstepping -- myths and realities

The lure of microstepping a two-phase stepper motor is compelling. Visions of microstepping a 1.8-degree hybrid stepper motor with 256 microsteps per full step flash in your mind. The resolution of 51,200 microsteps per revolution entices you. You're glad you don't own stock in high-resolution encoder companies. Where's the catch? The real compromise is that as you increase the number of microsteps per full step, the INCREMENTAL torque per microstep drops off drastically.

Fiber composite parts as strong as metal
The Mark X by Markforged is the industry’s most powerful fiber composite 3D printer. Markforged printers have two print heads. Combining carbon-reinforced nylon on one with revolutionary continuous fiber on the other results in parts that are amazingly strong -- as strong as aluminum. Breakthrough print capabilities for this machine include in-process laser inspection as well as a fine (50-micron) surface finish and a large build volume (13.0 in. x 9.8 in. x 7.9 in.).

Image - Coupling features WingLock technology
Coupling features WingLock technology
The Baldor-Dodge Raptor coupling features an optimized winged elastomeric element design to provide longer driven-equipment life and improved reliability. Raptor’s patented WingLock technology increases surface area at the most critical regions of the element, resulting in higher bond strength, improved fatigue resistance, and longer life than competitive urethane designs. A non-lubricated natural rubber element results in lower stiffness, improved vibration damping, and industry-leading misalignment capabilities. Designed for drop-in interchangeability, Raptor couplings work in existing applications without any modifications.

U.S. Navy commissions electric-propulsion stealth destroyer
The U.S. Navy has commissioned for service the USS Zumwalt, its largest and most advanced stealth destroyer. The 610-ft-long electric “multi-mission” ship can hit a target at a range of more than 60 miles, has a wave-piercing tumblehome design, and features a unique superstructure that makes it less visible to enemy radar.

New welding process joins dissimilar sheets better
Scientists at the University of Stuttgart in Germany have developed two new process variants that aim to expand the areas of application for friction stir welding considerably. Thanks to these procedural variants, it is possible, for the first time, to use friction stir welding to join steel and aluminum sheets of different thicknesses economically while ensuring high-strength joints.

Georgia Tech study finds 'lurking malice' in cloud hosting services
A study of 20 major cloud hosting services has found that as many as 10 percent of the repositories hosted by them had been compromised -- with several hundred of the "buckets" actively providing malware. Such bad content could be challenging to find, however, because it can be rapidly assembled from stored components that individually may not appear to be malicious.
