Abstract: A capacitor assembly having a spiral-wound, layered capacitor secured against movement in a cylindrical container. The capacitor is secured in the container between a closed end of the container and a lid closing an open end of the container, each having distributed projections which press into a respective end of the capacitor. The projections in the lid extend radially from the center of the lid and have a principal effect of minimizing rotational movement of the capacitor. The projections in the container bottom are in the form of raised solid bumps arranged in a circular pattern and have a principal effect of minimizing lateral movement of the capacitor.

Abstract: A pressure sensitive fault interrupter for a dry metalized AC motor run capacitor having a dome-shaped diaphragm secured to one electrode at the base of a capacitor roll such that a rise in pressure within said roll will cause the dome of the diaphragm to be depressed, thereby breaking the electrical contact of one electrode, thus isolating the capacitor from its power supply.

Abstract: A multisection AC capacitor having a pressure sensitive fault interrupter, said capacitor being a dry metallized AC motor start and motor run capacitor, said fault interrupter having a dome shaped diaphragm secured to one electrode at the base of one capacitor section within said unit and one or more core connectors spatially separating and securing said capacitor sections within a sleeve such that the multisection stacked capacitor may be potted within a case and gases resulting from a build up of pressure within said capacitor will be directed to its core and downward therefrom to exert pressure, causing the dome of the diaphragm to be depressed, thereby breaking the electrical contact of one electrode, thus isolating the capacitor from its power supply.

Abstract: A multisection AC capacitor wherein each capacitor section has a pressure sensitive fault interrupter having a dome-shaped diaphragm mechanically and electrically secured to a contact bridge at the base of the capacitor roll, all capacitor sections within said case being electrically connected in parallel, such that a rising pressure within one section will cause the dome of the diaphragm of the faulty capacitor to be depressed, thereby breaking the electrical contact of one electrode, thus isolating the faulty capacitor from the power supply, while permitting the remaining capacitors in the multisection unit to function normally.

Abstract: A pressure sensitive fault interrupter for an oil impregnated metallized AC motor start and motor run capacitor having a dome-shaped diaphragm secured to one contact electrode bridge at the base of the capacitor roll such that a rise in pressure within said roll will cause the dome of said diaphragm to be depressed, thereby breaking electrical contact of one electrode, thus isolating the capacitor from its power supply.

Abstract: An electrical dry metallized film capacitor includes a capacitor roll section, formed from a metallized film having connecting leads attached to the top and bottom thereof. The capacitor roll section is then coated with a non-stick coating and then inserted into a closed-end container, the connecting lead attached to the bottom of the capacitor roll section being dressed along the side thereof to the open end of the container. Potting compound is then inserted into the container up to the top of the capacitor roll section. Upon electrical failure of the capacitor, the non-stick coating allows gases, formed in the capacitor roll section, to axially shift the capacitor roll section thereby breaking the connection to the bottom connecting lead which is securely held by the potting compound.

Abstract: Disclosed is an insulative header assembly with electrical feed through terminals therein. The header includes at least one tapered opening therethrough. A depression or counterbore at the narrow end of the tapered opening forms a shoulder therewith. A metallic one-piece feedthrough terminal with a tapered portion is forced into the tapered opening tightly enough to form a seal therewith. Part of the tapered portion extends into the recess or depression. The metal in the depression is flared to overlap the shoulder and thus securely fix the terminal in place. There are splines in the depression, and the metal that is forced into the depression conforms to the shape of the splines and thus rotatably restrains the terminal in the header.
