Abstract: An intermediate precoat layer is provided for encapsulated electrical devices such as solid electrolyte tantalum capacitors. The intermediate precoat layer contains a resin material selected from the group of acrylic, styrene, cellulose acetate, polyvinyl chloride and certain epoxy type materials. The intermediate precoat layer of the present invention helps to stabilize electrical characteristics in the electrical devices such as reducing the DC leakage current in solid electrolyte tantalum capacitors after encapsulation by a protective layer.

Abstract: A pair of cooperating bevel gears cooperate to provide a coupling means between a constant speed drive means and a cam means.A motor is carried by a U-shaped frame which can be inserted into a timer housing, the U-shaped frame having means to align coupling means to provide a second motor drive for the timer.
Abstract: A thrust bushing is trapped between a rotor and a bushing in which a shaft carrying the rotor is rotated to provide better torque control as the shaft is rotated.
Abstract: A first rotor is fixedly carried by a shaft and a second rotor is loosely carried by the shaft. A coupling means couples the second rotor to the shaft through an interference fit with the second rotor. The two rotors are then adjusted with respect to one another by rotating the shaft while holding the second rotor in place.
Abstract: An electrolyte adapted for use in aluminum electrolytic AC motor start type capacitors comprising an acid selected from the group consisting of benzoic acid and toluic acid and mixtures thereof, at least one organic base which at least partially neutralizes the acid, and a solvent of ethylene glycol.
Abstract: An interval timer providing a relatively large number of settings between two extreme time intervals wherein two cooperating snail gears drive a drum and a cam, and wherein a partial gear disengages a motor drive means from one of the snail gears to intermittently stop the snail gears' rotation.

Abstract: A first rotating display means having indicia on its outer periphery, rotates within and in synchronization with a second rotating display means having indicia and a window on its outer periphery, the indicia for the first display means being visible through the window at selected times.
Abstract: An organic thermoplastic resin having dielectric properties is bonded to a substrate material by heating the plastic, bringing it into contact with the substrate, and applying an electric potential therethrough so as to join the plastic and the substrate together. The substrate material may be an electrical conductor such as a metal sheet or foil, or it may be a plastic of similar or dissimilar chemical composition or a glass or other dielectric.
Abstract: A porous dielectric oxide film-forming metal anode capacitor is provided with an anode riser means that is able to absorb energy by deforming or flexing when subjected to compressive forces such as the forces resulting from a crimping operation in the construction of the capacitor. The anode riser means comprises one or more continuous lengths of metal with at least a portion of one of the lengths in the shape of a bight.
Abstract: A cathode electrode of copper-based material adapted for use in an electrical device is provided with a layer composed of at least one compound from the group of copper selenide, copper telluride and copper sulfide by the reaction between the copper-based cathode electrode and an appropriate reactive compound of selenium, tellurium or sulfur. When utilized in an electrolytic capacitor, the layer on the cathode electrode helps to depolarize the capacitor and helps to increase the capacitance of the cathode electrode.
Abstract: A first shaft of two concentric rotatable shafts is axially displaceable with respect to the other. Switch opening and closing means is responsive to the axial displacement of the first shaft, the axial displacement being responsive to the rotational output of the second shaft. A cam means is carried by the second shaft.

Abstract: A method is provided for electroplating a solid electrolyte film-forming metal capacitor. The method includes placing an electroprocessed capacitor in an electroplating vessel which contains a plating source and electroplating solution, providing a voltage source and connecting the positive terminal of the voltage source to the anode side of the capacitor and to the plating source and the negative terminal of the voltage source to a conducting layer on the anode body, and then electroplating a layer containing metal over the capacitor. Any metal which can be plated may be used, such metals include electrically conductive metals such as silver, gold, copper, nickel, and mixtures thereof. The electroplated layer over the capacitor provides greater resistance to mechanical shock and allows the welding of a cathode termination means to the electroplated layer of the capacitor.
