Abstract: Method and apparatus are disclosed for producing pin operators for pressure switches in which the pin operator is adjusted in length while in a pressure environment with an associated diaphragm when subjected to proof pressure for the finished switch assembly. The pressure housing is preferably the actual switch housing. A die with a recess is aligned with the diaphragm and pin. The pin blank has an opening and tapered wall thickness. When proof pressure is applied to the opposite face of the diaphragm, the diaphragm forces the pin into the die recess to form the end of the pin and shorten its length. Thereafter the pin and diaphragm combination in the pressure housing will provide a prescribed travel when the diaphragm is subjected to proof pressure. An alternative device is disclosed for forming the ends of pins where proof pressure for the particular device is less than the required forming pressure for the pin. Semi-cylindrical, truncated conical and outwardly flared pin forms are disclosed.

Abstract: A Hall-effect device and a magnet are mounted on respective resonant bridge supports in magnetic field relationship whereby movement of either the magnet or the Hall-effect device produces a change in the field strength at the Hall-effect device. The two support structures with their mounted components exhibit different natural resonant frequencies whereby stimuli in either of two different ranges causes one or both of the magnet or Hall-effect device to move at their resonant frequency producing a signal. Signal processing circuitry disregards D.C. signals from the Hall-effect device and responds only to A.C. signals, indicative of shocks in the 1000 to 2000 Hertz range or movement of the detector with components in less than the 150 Hertz range. Three different bridge structures are disclosed, one with separate bridges, one employing common support columns and one which is integrally molded.

The cover includes a control line port through which control pressure is applied to the valve. Service brake delivery pressure for the brake system is available at the supply port of the relay valve and sealed from the two or more delivery ports by a pair of O rings sealing the spool to shuttle in the body.

Abstract: An automatic monitor for potable water quality which monitors total dissolved solids (TDS) in drinking water. Built into a faucet base are a pair of indicators in the form of one green and one red LED. A sensor in the form of a pair of spaced electrodes extends into the supply conduit for the faucet and measures the electrical resistances of the water in the conduit. A pulse power source powered by a battery supplies power to automatically periodically power the sensor and illuminate the green LED as long as the TDS level is below a preselected value. If the level exceeds the preselected value, the red LED is periodically illuminated. The duty cycle for operation and illuminating the LEDs is approximately 0.5% whereby battery drain is sufficiently low that months of continuous monitoring is possible using 4 AA batteries. No ON-OFF switch is needed. If neither LED illuminates once every two minutes, the batteries need replacement.
