FLUID POWER: Iwaki America Inc.’s HRP compact dc driven metering pump is designed for OEM fluid injection applications. Digitally controlled, high-resolution injection capability operating from 0-720 SPM with 0.055 cc/stroke offers consistent low volume injection capability. Its maintenance-free design with four external control options and availability in 12 or 24V dc configurations makes this an ideal OEM solution for dosing applications. The HRP Series offers four control options including pulsed input, 4-20 mA speed control, 1-5V dc speed control and stop/start for maximum integration flexibility into OEM systems. HRP pumps are available with 12 or 24V dc drives with flows ranging from 0 ml/min to 38 ml/m and pressures to 0.2 Mpa. The HRP design features pump end construction materials of PVDF with FKM gaskets, alumina ceramic valves and PTFE diaphragm for excellent chemical resistance and cost-effective handling of most fluids. The IP65 construction makes it dust and waterproof. Applications for the HRP include disinfectant injection for food and beverage industries, detergent injection for cleaning systems and in any OEM system where chemical injection is required.
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.
