Wraparound conveyor runs for 5 miles
For those readers who like big-equipment applications, here's a neat one. A closed-trough conveyor belt system from Continental helps transport pit coal in China's northern Shanxi province. The incredible setup, where the conveyor actually folds over to make its own tube and enclose the material, covers a distance of 5 miles -- replacing trucking the coal and all the time, fuel, and emissions that goes with it.

New device generates light from the cold night sky
A new, inexpensive thermoelectric device created by researchers at UCLA can harness the cold of space without active heat input, generating electricity that powers an LED at night. A huge benefit is that devices like this one are able to generate electricity in the dark -- when solar cells don't work.

Compression Springs for Demanding Applications
Compression springs are the most common spring configuration that product manufacturers turn to when enhanced product functionality is desired. Used in automotive, aerospace, general industrial, medical and technology products, this spring type is used to resist applied compression forces or to store energy in the push mode.

How to choose the best online CNC machine shop
Sourcing professionals, engineers, and designers alike need to have parts produced through technologies like CNC machining, turning, and milling. In development, the requirements may be loose to get a product validated. And in production, the expectation is that parts are made consistently, on time, and to specifications. But it is sometimes difficult to navigate through all the Internet searches and buzzwords to determine the best fit for your needs. Greg Paulsen from Xometry provides a useful guide on what to look for when selecting a machine shop.

Engineer's Toolbox: How to maximize retention of spring pins
Spring pins are used in many different assemblies for a variety of reasons: to serve as hinge pins and axles, to align components, or simply to fasten multiple components together. When properly implemented, they provide reliable, robust joints with excellent retention. SPIROL Application Engineer Evan Dowell runs through the dos and don'ts of using spring pins.

Hinge Selection Guide online app
The super-helpful Hinge Selection Guide online app from Reell Precision Manufacturing introduces a user-friendly resource to pinpoint ideal hinge and torque insert product solutions matching application requirements. This easily accessible tool opens an interactive window to designate an application's parameters, calculate the torque and rotational angle required for the hinge or torque insert, and ultimately identify the Reell products best suited for the job. The tool also enables users to access Reell's standard catalog products.

How to choose an anti-backlash lead screw nut
Lead screws are the norm for today's linear motion applications, but despite their advantages over competing technologies (i.e., affordability, precision, the ability to design with freedom, reduced maintenance, etc.), lead screw systems do have a certain amount of "play." An important design consideration for utilizing a lead screw is the amount of backlash your system can tolerate and still achieve its goal. The big question is: Which lead screw nut will help you in the battle against backlash? By Christopher Nook, Helix Linear Technologies

Marathon stainless steel and jet pump motors from AutomationDirect
New Marathon Powerwash SXT washdown duty motors are designed for use in food and beverage processing and other washdown environments. The all stainless steel, totally enclosed motors are available in single and three-phase. C-face with rigid base (footed) and C-face footless mounting options are available. Jet pump motors are commonly used in commercial and industrial water treatment and processing applications to power centrifugal and hydraulic pumps. Marathon jet pump motors are available in single and three-phase, and in TEFC and Open Drip Proof (ODP) designs. The ODP design allows air to circulate through the motor windings for cooling, but prevents drops of liquid from falling into the motor. The increased air flow means lower operating temperatures and increased efficiency when compared to TEFC or TENV motors.

Image - Emergency braking in power outages, long holding power
Emergency braking in power outages, long holding power
Miki Pulley's BXW Spring Actuated Electromagnetic Brakes utilize internal compression springs to provide power-off, fail-safe braking. The primary moving part in this robust but simple brake design is the armature plate. When actuated, the brake compression springs push the armature plate into the friction disc when power is disengaged. This feature provides fail-safe braking and allows the brake to maintain position over long periods of time, thus preventing machinery from "coasting" when powered off. Brakes are ideal for small and large applications, including use with servo motors. Additional features: quiet operation, high holding torque, space savings, long service life, stable and reliable braking power, and manual release mechanisms.

Image - Neat! Rexroth linear motion tech helps mini model aircraft take off and land at world's largest tiny airport
Neat! Rexroth linear motion tech helps mini model aircraft take off and land at world's largest tiny airport
Since it opened in 2011, Knuffingen Airport at Miniatur Wunderland in Hamburg, Germany, has handled around a million flights. The 1:87-scale model aircraft in the sprawling 125-m2 indoor airport are accurate down to the tiniest detail and look almost real when taking off and landing. Bosch Rexroth's highly reliable linear motion and assembly tech plays a key role in ensuring this fascinating project operates smoothly. The airport serves 40 airlines and handles 360 flights a day. It includes 50,000 figures, 75 buildings, and 90 support vehicles -- all made by hand. Night falls every 15 minutes and lasts 3 minutes. The Miniatur Wunderland also sports the world's longest train installation -- which, of course, is tied into the airport setup.

How Stratasys 3D printing powers innovation at Polaris
See how Polaris, maker of high-quality snowmobiles, Indian motorcycles, and some pretty extreme on- and off-road vehicles, is using Stratasys 3D printing to create innovative, efficient, and money-saving production solutions. The ability to create new tooling designs quickly is one main benefit of using additive manufacturing. This video is filled with many production-floor examples, so it is worth watching.

1962 VW Bus gets retrofit using generative design
To celebrate the 20th anniversary of the Volkswagen Innovation and Engineering Center in California, the company's team of designers, engineers, and scientists wanted to "do something memorable to represent Volkswagen's DNA while pushing the future of car design forward." So the team took a classic 1962 VW Bus and retrofit it with the latest technology, including generatively designed elements such as funky wheel rims and wing-mirror arms. In generative design, a computer program solves for design elements using set parameters -- like highest strength using the least material -- and then presents its solutions, which can often look bio-inspired. Watch the process of bringing a retro icon into the digital age using generative-design tech from Autodesk.
