FLUID POWER: The TridakModel 785 poppet valve can be used in numerous applications to dispense low-to-medium viscosity materials such as adhesives, silicones, greases, and other filled materials. This economical valve improves fluid dispensing accuracy and consistency.
The Model 785’s design minimizes friction between the actuating components of the valve and the material being dispensed. Minimizing this friction substantially decreases valve maintenance and down-time. The valve’s stroke adjustment and control feature offers precise adjustment of fluid deposit volume and flow. Material is shut-off cleanly at the end of each cycle, which is particularly significant for tacky or stringy materials. Peak performance is obtained when actuated with the Tridak Model 345 valve controller.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
