Innovative Way to Take Up Tolerances!
Smalley Linear Springs are a continuous wave formed (marcelled) wire length produced from spring tempered materials. They act as a load bearing device having approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

Sharpie marker trick helps multi-scale fluid dynamics experiment succeed
University of Chicago physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, achieved the first measurements of an elusive but fundamental property of fluid flow. "It's the wackier stuff that works" sometimes, said researcher Martin Scheeler.

Continental introduces new wheel and braking concept for electric vehicles

Continental has developed the “New Wheel Concept” to meet the specific requirements of electric vehicles (EVs). In contrast to conventional wheel brakes, the New Wheel Concept brake engages an aluminum disk from the inside. The particularly large diameter benefits braking performance. Another advantage of the concept is that it provides much easier wheel and brake pad changes.

Engineer’s Toolbox:
The emerging role of fractional calculus in military engineering and beyond

Although its development started in 1695, only in recent decades has fractional calculus been regarded as a tool with real-world applications rather than a concept that is purely in the mathematical realm. Dr. Bruce J. West, senior scientist of mathematics and information science, U.S. Army Research Office, gives his take on this increasingly important branch of mathematical analysis and its growing importance in real-world applications.

Image - Zinc foam with cost-saving feature
Zinc foam with cost-saving feature
Goodfellow has announced the availability of two variants of zinc foam: 99.99% zinc deposited on a polyurethane foam and ZAMAK 410 Zn /Al4/Cu1/Mg0.04 zinc alloy foam with solid ligaments. Both combine the versatile properties of zinc or its alloy with the functional benefits of a foam. This combination should be of particular interest to design engineers working in the fields of heat exchangers, catalyst substrates, energy absorbers, filters, and mixers. Cost-saving feature: For the variant deposited on a polyurethane structure, it is possible to design the finished component in the base foam before metalizing, avoiding post-machining and thereby reducing costs. Editor's note: Goodfellow copper foam has been a favorite of Designfax readers for years, so check that out too.

Self-clinching flush-head studs for thin metal sheets
PEM FHL and FHLS self-clinching flush-head studs from PennEngineering feature a unique low-displacement head design enabling close-to-edge installation of the fasteners in thin metal sheets. The studs provide ideal attachment solutions compared with weld studs and other conventional hardware by promoting easier and cleaner installation with fewer production steps and more reliable performance in service. Since the studs install permanently, they will never loosen or fall out over time.

Mini high-torque brush DC motor
Portescap introduces the new 16DCT motor to its high-torque DCT range of Athlonix motors. The 16DCT motor can deliver continuous torque up to 5.24 mNm at a length of only 26 mm. This motor uses powerful Neodymium magnets and Portescap's proven energy-efficient coreless design. The optimized self-supporting coil ensures that high performance is delivered in a compact package, reducing the overall cost of ownership. Compared to similar motors in the market, the 16DCT has the lowest motor regulation (R/K2), which means it has a lower drop in speed at increasing load. This provides the most powerful motor available for various challenging application needs, including battery-operated tools, security systems, humanoid robots, rotary tattoo machines, and more.

Why air bearings over mechanical bearings?
  1. Air bearings are frictionless and will almost always outperform a mechanical bearing at scanning, assuming similar controls.
  2. Air bearings never wear out.
  3. A cushion of pressurized air results in surface averaging effects, meaning extremely smooth, flat, straight motion.
  4. Scanning performance of air bearings is not affected by speed -- very slow or very fast.
  5. Air bearings provide wobble-free rotary motion.
