Instead of taking weeks or months to get some idea of corrosion rates, it is now possible to measure corrosion in hours or days with the use of this newly developed instrument. The Corrosometer measures electrically the progress of corrosion in any cor rosive system. It is used with special probes containing metal specimens which are subject to corrosion. Probes of more than 30 metals and and alloys are available. Dept. IEC, Crest Instrument Co., 11808 S. Bloomfield Ave., Santa Fe Springs, Calif.
Fluid Teflon Seal for Rotary Pump Here is a new idea in gaskets. The seal is arranged as an annular chamber around the pump shaft, in which two Teflon seal-ring retainers hold a fluid mass of Teflon. A screw in piston provides positive pres sure on the fluid Teflon, making a practical no-clearance fit which ef fectively eliminates the passage of gases or fluids into or out of the pump. Dept. IEC, Eco Engineering Co., 12 New York Ave., Newark 1, N. J.
