Abstract: Wound, solid state inductors are provided by winding flexible plastic tape having electrically insulative and magnetic permeability properties. Such tape is sometimes referred to as magnetic tape. An electrically conductive layer is placed on at least one surface of the magnetic tape, or both, and electrical connections are provided to the ends of the electrically conductive layer or layers. When the magnetic tape is wound into a coil, spirally or helically, and an alternating current is applied to the electrical connection, an inductive reactance will be noted. If there are two electrically conductive layers, and a voltage is applied between them, a capacitive reactance will be noted. In that case, a complex capacitive inductor element or inductive capacitor element has been configured. The wound inductors are small, light weight, inexpensive, and relatively shock proof, when compared with prior wound inductors having separate magnetic cones and wire windings placed over them.

Abstract: An adjustable clamping device for receiving and selectively frictionally engaging an internally disposed inserted member, such as a rope or rod, is disclosed. The clamping device comprises a flexible and readily deformable gripping member of a hollow cylindrical shape, disposed about a generally centrally located first longitudinal axis. The gripping member may comprise a substantially solid sheet of flexible material, or may comprise a mesh material, or may comprise a plurality of flexible strand members. The material for the gripping member may be leather, rubber, synthetic rubber, neoprene, cloth, nylon, rayon, kevlar, or metal, as appropriate. The gripping member is twistably deformable between a straight neutral configuration and a plurality of helically twisted configurations whereat the gripping member reduces in diameter and encloses down onto the inserted member.

Abstract: The present invention provides a system and a method for controlling electrical devices connected to an AC power line by means of control signals transmitted over the AC power line. The control system consists of a transmitter apparatus and a receiver apparatus. The transmitter apparatus generates, and transmits via an AC power line, multiple voltage pulses during any one-half cycle of the AC power line voltage. The multiple voltage pulses act as control signals for any electrical device that is sought to be controlled, or a "slave" device. The receiver apparatus is simultaneously coupled to the slave device and the AC power line for receiving and, if necessary, decoding the voltage pulses sent by the transmitter apparatus. The receiver apparatus in turn generates a command signal that controls the slave device's operation.
