 | Top Army priorities: Long-range precision fires, hypersonics
The Army's No. 1 modernization priority -- long-range precision fires -- is a collaborative science and technology effort between the Army and the other services, said Dr. Thomas Russell, deputy assistant secretary of the Army for research and technology, at a National Defense Industrial Association-sponsored forum recently. One area of intense focus is hypersonics.

 | Top Tech Tip: Nested Wave Springs from Smalley
Nested Wave Springs are pre-stacked in parallel from one continuous filament of flat wire. The need to stack individual springs for higher loads is no longer necessary. Nested springs result in a spring rate that increases proportionately to the number of turns. They can exert tremendous forces, yet maintain the precision of a circular-grain wave spring. In many applications, Nested Wave Springs replace Belleville Springs, particularly in cases where a high but accurate force is needed.

 | Precision motion for X-ray optics
Despite their potential danger, X-rays are one of the most powerful instruments and resources utilized in medical diagnostics to help medical professionals restore health by identifying the correct prognosis. When it comes to achieving the best imaging with the lowest X-ray exposure, lenses made by Optec are almost inevitably involved. Their aperture, focus, filters, and zoom are precisely moved by FAULHABER DC motors.

 | 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.

 | New bearings for high-speed applications
A clear trend in compressor and pump applications is to raise the power density by increasing the rotational speed. To fulfill this requirement, SKF has developed a new range of single-row angular contact ball bearings. The goals have been threefold: to increase the limiting speed by 40 percent, to reduce the noise levels, and to increase the robustness of the bearing in unfavorable operating conditions (shock loads, shaft misalignment, etc.). Apart from these, SKF is helping manufacturers to meet customer demands for even higher levels of energy efficiency and reliability.

 | What are the strongest adhesives for bonding titanium?
Master Bond's labs recently tested the tensile lap shear strength of a variety of adhesives when bonding titanium to titanium. The surfaces were properly roughened and cleaned with acetone in preparation for the tests. Each of the 11 one- and two-part epoxies tested features different thermal, electrical, and chemical resistance properties that can make them more appealing for specific applications. Therefore, it's important to consider the operational conditions before deciding that the system with the highest strength value is the best for the titanium bonding job.

 | 100 years ago: Final Allied offensive of WWI decided fate of Europe
By mid-September 1918, the French and U.S. armies under the command of Gen. John J. Pershing had achieved victory in a critical campaign, driving back the Germans from the Saint-Mihiel salient. With that area secured, about 600,000 Americans, along with some 220,000 French and Italian troops, moved 40 miles to the northwest along the bank of the Meuse River in the Meuse-Argonne region of France.

 | New Chevy Silverado with advanced 2.7L Turbo rivals some V6 models
More torque, higher horsepower, and better city mpg. What truck owner wouldn't want that? The all-new 2019 Chevrolet Silverado 1500 with 2.7L Turbo offers full-size truck customers 14 percent more torque and 13 percent better city fuel economy than the 4.3L V6 it replaces (plus it's more than a full second quicker from 0 to 60 mph). This four-cylinder turbo is a first for Chevy -- and for any full-size pickup.

How 3D printing is transforming foundries
3D Systems recently announced the availability of its new 3D-printing solution for investment casting professionals. The ProJet MJP 2500 IC produces RealWax patterns in a fraction of the time and cost compared to traditional pattern production. This digital foundry solution is designed to transform a centuries-old manufacturing process. "The wax patterns produced on the ProJet MJP 2500 IC are incredible," says Al Hinchey, 3D print manager, Invest Cast. "The complexity of parts that we can now produce has enabled new functionality that we can offer our customers."
