Abstract: A polycrystalline varistor of the bulk effect zinc oxide base type adapted for use in voltage surge suppression on VHF signal lines is disclosed. The device comprises a unitary body including a spiral inductor electrically in series with the varistor element to prevent capacitive loading of the protected signal line.

Abstract: A body of sintered metal oxide material having first and second opposed surfaces and a third surface disposed therebetween has first and second electrodes in contact with the first two opposed surfaces for establishing a main conductive path through the device and a third electrode in contact with one of the two opposed surfaces and spaced very close to the corresponding electrode for establishing a monitoring conductive path for sensing the operating temperature of the body as a function of the resistance thereof. The monitoring path may also be established by a pair of third electrodes positioned on opposite sides of the surface interconnecting the first two surfaces whereby the monitoring path intersects the main conductive path. The sintered metal oxide material has varistor characteristics.

Abstract: A signal is derived corresponding to variations in the unidirectional current flowing in the external power lines to a direct current rotating machine. A second signal is derived from the first signal having a period equal to the period of revolution of a commutator divided by the number of commutator segments. The appearance in the second signal of peaks short in duration in relation to said period indicates a defect in commutation of current in the armature winding of the direct current machine.

Abstract: In a coaxial connector a generally toroidal shaped member of metal oxide varistor material is connected between the inner and outer conductors of the connector. The metal oxide varistor material has an alpha in excess of 10 in the current density range of from 10 3 to 102 amperes per square centimeter. The spacing of the peripheral portions of the member is set so that a high impedance is presented to normal applied voltage between the peripheral portions. For voltages applied between the peripheral portions progressively in excess of the normal voltage rapidly decreasing impedance is presented by the toroidal member in accordance with the alpha of the material thereby limiting the variation in voltage between the peripheral portions of the toroidal shaped member.
