ID/OD Retaining Ring Lock Spirolox Retaining Rings can operate in an internal and external groove at the same time. Install the ring in one groove and then compress the ring with the mating component into the second groove. When the grooves meet, the ring snaps into place creating a low-cost, hidden, high-strength, tamper-proof rotating joint. Over 6,000 rings are stocked from 1/4" to 16" diameters in carbon and stainless steel; customs up to 120".

Wheels: Volvo unveils triple-boosted 450-hp 4-cylinder engine |
|
 They are keeping a lot the details still under wraps, but Volvo unveiled a triple-boost 2-liter 4-cylinder gasoline engine with no less than 450 hp on October 9.
The new engine is the next-gen version of Volvo's 320-hp Drive-E Powertrain range that debuted in 2013 -- an engine that solidified the carmaker's commitment to developing powerful and fuel-efficient 4-cylinders for its passenger-car and SUV lines.

Adaptive zoom riflescope prototype features push-button magnification Sandia National Laboratories optical engineer Brett Bagwell (an Army Special Forces officer-turned-engineer) led the development of the Rapid Adaptive Zoom for Assault Rifles (RAZAR) prototype. At the push of a button, RAZAR can toggle between high and low magnifications, enabling Soldiers to zoom in without having to remove their eyes from their targets or their hands from their rifles. The flexible, polymer-based optics are based on the human eye.

New developments boost LED brightness and efficiency big time For all of their trumpeted efficiency, did you know that only 2 to 4 percent of the light generated by a standard LED escapes from inside the device? Wow, either did we! With all that trapped light energy, no wonder they get hot. But Princeton University researchers are onto something big to change this, including a 57 percent improvement in brightness and efficiency.

Engineer's Toolbox: World's smallest production V8 optimized with precision honing Gary Conley's 30-year quest to manufacture a true production V8 engine in quarter-scale almost went up in smoke twice: once in 2001 when a foundry fire claimed all his critical molds, and later when oil smoke proved a stubborn problem during run-offs of the engine. Conley overcame the first setback with years of sheer determination. The second issue required a Sunnen MB 1660 honing machine, abrasives, and some Sunnen know-how.

Wings: LabVIEW and NI CompactDAQ get the Skylon space plane project off the ground Current space propulsion systems based on rocket technology alone place limits on the performance of launch vehicles, which leads to multistage vehicle configurations that are either expendable or only partly reusable. This results in complex launch systems that are both high maintenance and expensive to operate. REL's Skylon space plane, a fully reusable single-stage launch vehicle, addresses these drawbacks and could revolutionize future access to space by providing more efficient and reliable launch operations. Michael Hood of Reaction Engines Ltd. talks about developing and testing the Skylon Mach 25 engines.

Wheels: Mercedes ditches aluminum pistons in favor of high-strength steel Think aluminum is the key to lightweighting automobiles and creating efficiencies in the future? Mercedes-Benz doesn't -- at least not for pistons. The company is switching to a high-strength steel piston design for a future line of its diesel passenger-car engines.

Great references: Basics of Hydraulic/Pneumatic Cylinders design guide After a reader asked us about some hydraulic cylinder basics, we were reminded of an excellent resource from Milwaukee Cylinder that interested engineers should download for themselves. Milwaukee Cylinder's Design Engineer's Guide does a fantastic job of covering basic cylinder operating principles, standard NFPA mountings, cylinder sizing, air and hydraulic cylinder force and speed, and much, much more. This is a no-cost, no-sign-up invaluable reference. Design Engineer's Guide is the 11th item on the page. Other good materials available. Click here to go to the Guide page.

A little fun and inspiration: Paper airplane machine gun |
|
| A Designfax reader tipped us off to a YouTube user called Papierfliegerei, who says that he has created a paper airplane folding machine that shoots out the little flyers machine-gun style. He says he had most of the parts 3D printed and uses a cordless screwdriver as the main motor component. Pretty inventive if you've got the time and motivation.
