Abstract: A control system, as for controlling automotive body functions, is powered by a limited capacity electrical power source and is structured and controlled in a manner to minimize consumption of electrical power. The control system conducts data transactions between a central control station and one or more remote controllers connected therewith, and the central control station includes a provision for electronic signal processing for controlling the data transactions with the remote controllers. A power FET is operatively connected to the power source and to a portion of the control system for selectively connecting or disconnecting power to that control system portion. The system employs a NMOS microprocessor. The portion of the control system from which power may be disconnected will typically include the processor. The level of system activity is monitored and a power-down, or "sleep" control signal is automatically provided if a predetermined condition of inactivity occurs.

It is also substantially all polyfunctional organosiloxane reacted, i.e. substantially no polyfunctional organosiloxane is capable of being extracted from the cured coating with organic solvents.

Abstract: Automotive ignition wire with a high temperature rating, excellent electrical insulating properties, heat resistance, oil resistance and abrasion resistance is described. The wire utilizes a conductor made up of either a helically wound metal conductor on a radio frequency insulating polymer overcoated on a polymer adhesive layer on a glass fiber bundle; or a glass fiber-cotton fiber braid on a graphite impregnated glass layer. Overcoating either one of the conductors is a semiconducting polymer layer, and a polymer jacket material. The polymer jacket material comprises a polymeric mixture of ethylene vinyl acetate and ethylene-propylene-diene monomer stabilized with a mixture of a phenolic antioxidant and a metal salt antioxidant.

Such mica products have excellent flexibility, structural integrity and improved moisture resistance.

Abstract: A continuous, high speed process for cutting a length of wire into wire segments and for forming these segments into coils includes the steps of continuously pushing the wire through a cutter at a constant speed, cutting the wire into a succession of wire segments, and directing the segments, in sequence and at the constant speed, to coilers, where they are coiled "on the fly". When a wire segment is completely wound, it is automatically removed from the coiler, whereby the coiler is empty and ready to receive another segment. While one coiler is coiling one of the wire segments, the next segment is directed to a different coiler which is empty. This allows continuous high speed movement of segments through the cutting and coiling process, with no space between the tail end of one segment and lead end of the next segment. Process efficiencies are substantial, and reduce the cost of the coiled wire products.

Abstract: A magnet wire enamel having improved runnability and insulating properties is described comprising nylon containing 0.25% to 20% by weight titanium chelate. The nylon can be a sole coat, outermost coating, or bond coat.

Abstract: A process for winding a wire segment to form a wire coil includes the steps of rotating a mandrel by contacting the mandrel outer surface with a moving belt, and directing the wire onto the rotating mandrel between the belt and the mandrel outer surface. The belt holds the wire against the mandrel, and as the mandrel rotates, the wire is wound into a coil on the mandrel outer surface. The belt continues to contact the coil outer surface and to rotate the mandrel until the entire length of the wire segment is wound. As the thickness of the coil increases, the belt partially unwraps from the coil outer surface to adjust belt tension. In one embodiment of the present invention, the belt passes around a pulley attached to a rotatable ring which moves the pulley in a circular path about the axis of the mandrel to cause the belt to unwrap from the coil as the wire builds up on the mandrel.

Abstract: A heat shrinkable tubing is described which has a texturized surface. Upon applying the heat shrinkable tubing to a complex shaped object and applying heat the tubing shrinks radially and linearly, uniformly so as to preserve the texturized friction surface, shrinking over depressions and expansions of the complex surface without wrinkling.

Abstract: A conduit for carrying a wire being pushed in a downstream direction comprises a duct having an internal flat bottom surface, and fingers spaced along the length of the duct and disposed above the bottom surface, each finger extending downstream and substantially across the width of the duct. The fingers are resiliently movable in a direction which is substantially perpendicular to the bottom surface of the duct when they are struck by the wire, and maintain the wire close to the bottom surface as the wire moves through the duct. The fingers allow the wire to be pushed at a high speed over long distances, and without the wire being twisted, jammed or damaged in the duct.

Abstract: An apparatus for cutting a length of wire into wire segments includes a pair of adjacent knife carriers, each disposed for rotation about parallel eccentric shafts. The knife carriers each hold a knife blade having a cutting edge. The cutter is constructed and arranged such that the carriers can selectively rotate about either the axis of rotation of the eccentric, wherein the cutting edges do not cut the wire passing between the cutter, or they can rotate about the center of the eccentric, wherein the edges will cut the wire. When the cutting edges cut the wire, their tangential speed is the same as the wire speed.
