    Abstract: A piezoelectric crystal comprising an elongated bar-shaped crystal having a pair of parallel spaced lead wires depending orthogonally from nodal points on one surface of the crystal and an elongated bar-shaped base in spaced relationship to the crystal and supporting the lead wires. The base is provided with conical shape holes with the larger diameter ends thereof proximal to the crystal, and sealing and securing means locate the hermetical seal between the lead wires and the base distal from the crystal enabling the lead wires to vibrate freely within the conical holes of the base. The length of the lead wires between the crystal and the point of attachment to the base is one-quarter wave length to return to the crystal a maximum percentage of the vibrational energy transmitted into the lead wires from the crystal thereby minimizing energy dissipation of the crystal while maintaining both a minimum distance between the crystal and the base and providing a minimum package size for the crystal. A cover cooperates with portions of the base to enclose the crystal.

    Abstract: A variable resistance slide control employs a housing having a front wall and a side wall integral therewith. A dielectric base having a resistance element and a collector element mounted thereon is secured to the housing in spaced parallel relationship to the side wall. A contactor engaging the resistance and collector element is constrained to move with a slider projecting outwardly of the housing through an elongated slot defined by the front wall and the base. The slider comprises a U-shaped section bearing against and interfitting with the front wall, a contactor frame provided with a pair of runners engaging the side wall, and a tolerance compensator limiting lateral movement of the slider. A pair of terminals secure the resistance element to the base and a bowed portion integral with each of the terminals electrically engages the resistance element at the innermost portion of the terminals.

    Abstract: A tandem electrical control comprises a plurality of variable resistance sections. Each resistance section comprises a resistance element and a collector member that are carried by a base, and a contactor member that is carried by a driver, the contactor member is rotatably supported within the respective housing and wipingly engages the respective resistance element and collector member. A tubular shaft controls the forward resistance section and is rotatably supported within a bore of a mounting bushing. An inner shaft controls the rearward variable resistance section and a switch and is rotatably supported within the tubular shaft. The bore of the mounting bushing, the outside diameter of the tubular shaft, the bore of the tubular shaft, and the inner shaft are each provided with a narrowing diameter shoulder in abutting engagement with the proximate one of the shoulders for preventing impact damage to the resistance assemblies from external forces axially applied to the shafts. One of the collector members is provided with at least one radially elongated depression and a contacting protrusion is disposed on the corresponding contactor member so that when the contactor protrusion engages the collector depression a tactile sensation is transmitted to the corresponding shaft.
