Abstract: A protective cover for cable connectors and methods of fabricated the protective cover. The protective cover comprises a tube open at one end and substantially closed at the opposed end by an end cap. The end cap bears at least one opening formed therein. The protective cover has a foil outer layer, a soft felt inner layer, and an insulating fiberglass core between the outer and inner layers. The tube is made by overlappingly rolling and bonding a section of foil-backed fiberglass. The end cap may be separately made, made as part of the pattern for the tube, or may be formed by cutting pointed teeth into one end of the tube pattern and bonding them generally perpendicularly to the length of the tube.

Abstract: Provided is a plaque and its method of manufacture, the plaque including a binding material and a reinforcing material that is molded into a controlled thickness. Also provided is a solder pallet utilizing the plaque in its manufacture. The plaque can be manufactured by forming a preform of the raw materials, optionally preheating the preform, molding the preform into a plaque of the desired thickness, and then cooling the plaque at an elevated temperature to maintain the flatness of the plaque without the need for sanding or otherwise machining the plaque to the desired size. The plaque can then be formed into the desired solder pallet by cutting the plaque to appropriate dimensions, if necessary, and adding holes and/or clips for use in a soldering process for soldering circuit boards, for example.

Abstract: The present invention includes a method of lining a core slot that includes the steps of unwinding a tube, separating a portion of the tube, inserting the tube into a core slot, and expanding the tube to line the core slot. The present invention also includes a continuous piece of helically-wound tubing that is wound on a spool along with an apparatus and method used for creating the spool of tubing. The method includes the steps of helically wrapping a web of material in an overlapping relationship to form a helically-wound tube, advancing the tube in a longitudinal direction of the tube and winding the tube onto a spool while at least a portion of the tube is being formed by the step of helically-wrapping. Method variations in which one or more of the aforementioned steps may be eliminated as appropriate, can be used for many other uses.

Abstract: A multiple spiral tube assembly having a plurality of nested tubes, each of a different size and made of an insulating material. One tube is inserted within another tube to form a flexible, multiple-layer tube assembly. The tubular assembly is slipped over an electrical conductor to form a flexible, multi-layer, thick wall construction for coil lead insulation.

Abstract: The present invention relates to a glass flake material having high thermal conductivity. The glass flake material can be used in the manufacture of insulating materials for electrical insulation applications, and, more specifically, relates to a sheet material having high thermal conductivity. The use of the glass flake in the sheet material can be used to enhance the thermal conductivity of high voltage ground walls in large motor coils and generator coils for example.

Abstract: A method for producing an electrically conductive filler by placing a web of core material onto an interior surface of a web of conductive layer material. The webs of core material and conductive layer material are directed through a forming station for folding the conductive layer around the core. The filler having a substantially non-conductive core and a conductive layer. The conductive layer is wrapped around the core to form a closed loop thereby establishing conductivity from a bottom of the filler to a top of the filler by paths on each of two sides of the filler.

Abstract: A method of forming a flexible spiral-wound tube includes the steps of spiral wrapping at least two webs of material in an overlapping relationship about a mandrel to form a multi-ply tube and advancing the tube along the mandrel and off a reduced diameter portion of the mandrel at a forward end of the mandrel. Advancement of the tube along the mandrel includes rotating the tube as the tube longitudinally moves such that the tube advances in a spiral manner. The method further includes the step of retarding movement of the tube along the reduced diameter portion of the mandrel by providing frictional resistance between the tube and the mandrel to form folds or pleats in the tube so that the tube becomes extremely flexible. The flexible spiral-wound tube has a uniform pattern of generally diamond-shaped folds therein.

Abstract: A device for adjusting the tension on a web slitter-rewinder drive belt assembly.

Abstract: A locking apparatus for an electrically actuated garage door opener assembly is disclosed for preventing the unauthorized entry into a home or building. The locking apparatus comprises an electric solenoid and associated plunger and is electrically connected to the electrically actuated garage door opener in order to selective lock and unlock the garage door. In the deactivated condition of the opener, the plunger provides a locking mechanism. When the opener is activated, the solenoid is energized and the plunger is withdrawn from its locking position, thus permitting the door to open. An important feature of the present invention is a sensing mechanism which senses the locked and unlocked position of the solenoid plunger. If the plunger is in the locked position, the sensor will prevent actuation of the opener, thereby avoiding damage to the door or opener.
