Seal It, Protect It!
A Smalley Laminar Seal Retaining Ring is a metallic labyrinth seal consisting of multiple rings in a groove. To seal an assembly from contamination while withstanding high temperatures and corrosive environments, Laminar rings are produced from metal, not rubber, neoprene, or other non-metallic materials. The arrangement of the rings and the specific orientation of the rings are dictated by the application and the severity of the environment. Numerous configurations are available; standard sizes from 5/8” to 50”.

High-strength steel:
There's nothing like a good crisis -- how the spark of urgency benefits innovation

History demonstrates time and again that humans often do their most innovative work when they are under the greatest pressure. In the automotive industry, it was the 2012 announcement of much stricter fuel economy standards for 2025 that shook up the OEMs. Craig Parsons, President of Automotive, NanoSteel, talks about the coming generation of advanced high-strength steels (AHSS).

Keepin' it really real: Stratasys redefines state-of-the-art 3D printing
Stratasys unleashed its top-of-the-line J750 multi-color, multi-material 3D printer on the world yesterday, a machine so advanced that it sets a new benchmark for the industry as a whole. Users can choose from more than 360,000 different color shades plus multiple material properties -- ranging from rigid to flexible, and opaque to transparent -- all in the same part. Just look at this sports-shoe prototype, which was produced with full-color, smooth surfaces and a rubber-like sole in a single print operation.

Plastic 10x tougher than ABS -- and recyclable to boot
Researchers at the Department of Energy’s Oak Ridge National Lab have made an impressive thermoplastic by replacing styrene with lignin, a brittle, rigid polymer that, with cellulose, forms the woody cell walls of plants. They have invented a solvent-free production process that produces a meltable, moldable, ductile material that’s recyclable and at least 10 times tougher than ABS.

Cool Tools: Self-powered IoT starter kits feature EnOcean and IBM technologies
Global electronics distributor element14 has launched two cutting-edge Internet of Things (IoT) starter kits that tap into technologies from EnOcean and IBM. Both the Entrepreneur and Enterprise kits feature micro-computer boards from element14 and energy-harvesting wireless sensors from EnOcean, and provide seamless integration to IBM’s Watson IoT Platform. Using the popular Raspberry Pi single-board computer, these out-of-the-box, IoT-ready starter kits are flexible and cost-effective gateways to developing intelligent building products for hospitals, homes, airports, and other venues on the way to a seamlessly connected IoT. The Entrepreneur kit is more technical in nature (for engineers, makers, and startups), while the Enterprise model caters to facilities managers, property owners, and property management companies.

Engineer's Toolbox:
The advantages of using edge-bonded shims

Precision shims are thin pieces of material often used as compensators to fill in small gaps between objects aligning parts, reducing wear, and absorbing tolerances between mating components. Shims can also significantly reduce manufacturing time and costs. Christie Jones of SPIROL Corp. runs through shim types (laminated, surface bonded, and edge bonded) and offers their advantages and disadvantages.

Motion: Neat! Plug-and-play motion system in a box
Rollon Corp. has launched Motion Box, a new pre-engineered Cartesian robot system designed to deliver users six different motion profiles that can be set up and running in a couple of hours. Motion Box covers everything from the human-machine interface (HMI) on one side to the output of reliable motion on the other end. Even the cable management is included. The initial system setup is already complete, so end users can get parts moving in a reliable and repeatable manner. Motion Box incorporates the Q-Motion Controller from Mitsubishi Electric, which features four-axis motion control, energy-efficient drivers, integrated I/O and network access, and a clean, efficient HMI setup.

Fans: Industry's first airflow monitoring kit
Orion Fans has developed a complete, cost-effective airflow monitoring system that is easy to implement and use. The field-retrofittable AFM Kit includes an AFM-01NC airflow module, mounting clip, three plastic guards (80 mm, 92 mm, and 120 mm), buzzer, LED and holder, switch, and wall-mounted power supply. The kit comes completely assembled in a 10-ft wire assembly, making installation easy. Placed on the output or input side of an AC or DC fan or blower, it operates an optical LED and/or audible alarm when airflow falls below 8.2 ft/sec due to fan filter clogs, foreign objects come in contact with the fan blade, or there is a fan failure.

Honing gives drag racers winning finish

Winning finish has a double meaning for Elite Performance, where the honing expertise of co-owner Nick Ferri has put the “winning finish” into engines behind 57 national NHRA Pro Stock wins and five championships, including back-to-back titles for 2015 Pro Stock Champion Erica Enders-Stevens. Ferri says honing finish rates a "10" in importance for engine seal-up, which translates into higher vacuum, greater fuel pull, and ultimate track performance.
