Patent number: 4406999Abstract: A sensor which conveys a displacement of an object into a change of inductance with which associated circuitry can be used for monitoring the displacement of the object. The sensor includes a coil maintained about a housing in which is disposed a ferromagnetic core about which is disposed a sleeve made of a conductive material and movable between the core and the coil with the induction of the coil variable in accordance with a predetermined relationship to the displacement of the sleeve with respect to the core with the monitoring of the change in induction indicative of displacement of the object. The sensor can be designed for determining both axial or rotational displacements of an object.Type: GrantFiled: July 2, 1981Date of Patent: September 27, 1983Assignee: Clarostat Mfg. Co., Inc.Inventor: Frank L. Ward

Patent number: 4284969Abstract: A potentiometer having in combination a non-electrical conducting substrate, a thin layer of resistance and collecting material on the substrate, a wiper movable thereon, providing communication between the resistance material and collecting material; the wiper and substrate contained in a durable housing with the wiper located on a carrier located above the substrate, supported by a shaft and rotationally fixed by a guide rail whereby axial force on the shaft casues a change in position of the wiper resulting in a change of resistance and voltage output which may be monitored.Type: GrantFiled: November 9, 1979Date of Patent: August 18, 1981Assignee: Clarostat Mfg. Co., Inc.Inventor: Victor Carbonneau

Patent number: 3934216Abstract: A multi-position detent device in which a plurality of detent positions are available with each position determined by discrete magnetic fields established between stator and rotor pole pieces and in which both stator and rotor have a magnet sandwiched between pole members in which the pole pieces radially project with respect to the stator and rotor pole pieces of opposite polarity projecting toward each other.Type: GrantFiled: December 11, 1974Date of Patent: January 20, 1976Assignee: Clarostat Mfg. Co., Inc.Inventor: Frank L. Ward
