Patent number: 6556425Abstract: A simpler, lower-cost way of installing polymer capacitor canisters on motors and other equipment. A bracket and/or fastener is attached to the canister (e.g., by ultrasonic welding a polymer fastener or bracket directly to the polymer canister), and the fastener and/or bracket are used to make the connection between the canister and the equipment. E.g., fasteners may be chosen so that they mate with holes or matching fasteners on the equipment to which the capacitor is being attached. Depending on choice of fastener, installation of the capacitor becomes a simple snap-in action. The capacitor manufacturer can now easily manufacture capacitors with a wide range of built-in fastener arrangements, relieving the equipment manufacturer of most of the work formerly associated with installing a capacitor on equipment.Type: GrantFiled: May 1, 2000Date of Patent: April 29, 2003Assignee: Parallax Power ComponentsInventors: Martin Hudis, Glenn Grenier, David Jenkins

Patent number: 5615078Abstract: A film capacitor in which the unmetallized margin is provided with a semiconductive layer. The layer provides a parallel resistive path within the capacitor, itself, obviating the need for an external resistor. It also grades the electric field across the margin, i.e., makes the field more uniform, thus allowing the margin to be made narrower without electrical breakdown, permitting a reduction in the physical size of the capacitor. A refractory, semiconductive layer is provided between the metal layer and the dielectric film. The refractory layer accelerates the self-clearing process, by insulating the underlying dielectric film from the heat generated by the vaporizing metal, thus hastening vaporization and reducing the tendency of the dielectric film to carbonize. As a result, faults are cleared with substantially less energy consumption. Preferably, the refractory layer is also semiconductive, to reduce field emission effects, and thereby decrease the frequency of faults in the dielectric film.Type: GrantFiled: December 16, 1994Date of Patent: March 25, 1997Assignees: Aerovox Incorporated, Toray Industries, Inc, Toray Plastics America, Inc.Inventors: Martin Hudis, Mamoru Koebisu, Kenji Hatada

Patent number: 5381301Abstract: A polymer-encased capacitor with a pressure sensitive interruption (PSI) system includes a polymer cover attached to a polymer case, the polymer cover having a skirt-less outer portion ultrasonically sealed to an open end portion of the polymer case. The polymer cover does not include flanged or lipped members extending from the outer edge of the cover (i e., "skirt-less") so that application of ultrasonic energy to the cover does not excite modes of vibration in which vibration nodes occur at intervals around the periphery of the cover, thereby providing a more leak-tight and rupture-proof bond between the capacitor case and cover.Type: GrantFiled: May 11, 1993Date of Patent: January 10, 1995Assignee: Aerovox IncorporatedInventor: Martin Hudis

Patent number: 4132829Abstract: A plasma polymerization process for the deposition of a dielectric polymer coating on a substrate comprising disposing the substrate in a closed reactor between two temperature-controlled electrodes connected to a power supply, maintaining a vacuum within the closed reactor, causing a monomer gas or a gas mixture of a monomer and diluent to flow into the reactor, generating a plasma between the electrodes, and varying and controlling the dielectric constant of the polymer coating being deposited by regulating the gas total and partial pressures, the electric field strength and frequency, and the current density. A monomer, such as a polar saturated or unsaturated nitrogen-containing compound, or a monomer and diluent, such as a saturated or unsaturated aliphatic hydrocarbon and nitrogen, can be polymerized to form a dielectric coating having a varying dielectric constant in accordance with this plasma polymerization process.Type: GrantFiled: February 11, 1977Date of Patent: January 2, 1979Inventors: James C. Administrator of the National Aeronautics and Space Administration, with respect to an invention of Fletcher, Martin Hudis, Theodore Wydeven

Patent number: 4109228Abstract: A current limiting fuse construction including a fuse element extending between electroconductive terminals carries a body of arc-quenching filler material within a hollow casing of electric insulating material. The filler material includes loose granular insulating material, such as sand, and larger particles of material uniformly distributed throughout the sand as a resin vaporizable in response to the heat of an arc current. According to a second embodiment a stratified filler comprises uniformly spaced layers alternately occurring between sand and a sand/resin mixture to increase arc voltage.Type: GrantFiled: April 18, 1977Date of Patent: August 22, 1978Assignee: Electric Power Research Institute, Inc.Inventors: Daniel A. Wycklendt, Martin Hudis
