Latest Patents

One of his latest patents is the "Tachometer kit with alternator pick up." This vehicle tachometer kit includes a pick-up coil that can be mounted on the outside of a vehicle's alternator. It senses the rotating field without requiring disassembly. The induced signal in the coil from alternator field leakage provides the normal input to a user-calibrated r.p.m. display driving circuit. This circuit can be calibrated for different alternators and drive pulley ratios without needing another tachometer. By selectively applying a simulated input reference signal to the display driving circuit, users can adjust the r.p.m. display until a scheduled ratio is achieved between the displayed r.p.m. and the reference signal.

Another significant patent is the "Pressure sensor and regulator for airless material coating system." This airless paint or material spray system features a pressure sensor and regulator that controls the pressure of paint flowing from a paint pump to an airless spray gun. The system includes three contiguous flexing diaphragms in a material chamber in the outlet flow line of the pump. The outermost diaphragm is in direct contact with the material and is constructed of a thin plastic impervious to common painting or coating materials. The two other diaphragms are rubber-coated fabric diaphragms that position a precision steel rod movably mounted in a low clearance bore in a regulator housing. The axial movement of the precision rod is converted to rotational movement by an adjustably spring-biased, pivotally mounted member in the housing. This member has a universal connection with the precision rod. A normally closed snap action switch in the housing is actuated after a predetermined axial travel of the precision rod, which energizes a dumping valve in the outlet of the pump to maintain a desired pump outlet pressure.
