Abstract:
An emission control device (10) and method are provided for treating exhaust to reduce pollutants contained therein. The device (10) includes a first chamber (16) through which the exhaust passes. First and second grids (26 & 30 respectively) are disposed within the first chamber (16) at a predetermined distance from each other. Voltage is supplied to the insulated first grid by an electrical induction coil (14) at a predetermined frequency depending upon the application. The induction coil includes an insulated center wire (34), a plurality of bare wires (36) juxtaposed in a curvilinear row and coiled about the center wire(34), and a plurality of insulated wires (38) juxtaposed in a second row and coiled around the bare wires (36) to provide a highly efficient conductor which also dampens any magnetic field created by the conductor (10) and thereby abates creation of random cycling frequencies in adjacent wiring.
Abstract:
The invention relates to an overload protection unit, especially for the starter of an internal combustion engine, which comprises a first contact (1) that is electrically connected to a second contact (2) in the inactive state of the overload protection unit by the effect of a material (3). When the temperature of the material (3) exceeds a predetermined value, said temperature deforms and/or modifies the material (3), thereby interrupting the electrical connection between the first contact (1) and the second contact (2). According to the invention, the material is solder (3). The invention further relates to an electrical machine that comprises the overload protection unit according to the invention, and to the use of a soldering joint as an overload protection unit.
Abstract:
An assembly includes an electrically conductive mounting bracket, a current limiting device electrically connected to the mounting bracket, and a fuse assembly that includes a body and a fuse. The electrically conductive mounting bracket is configured to mount about the body of the fuse assembly, and, when the electrically conductive mounting bracket is mounted about the body of the fuse assembly, the mounting bracket forms a path for electrical current between the current limiting device and the fuse.

Les trois seuils de déconnexion étant inférieurs au seuil énergétique de fonctionnement.
Abstract:
A fuse for a high voltage/high current application, such as a hydro-electric vehicle ("HEV") application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.
Abstract:
The thin film, electrical device is a subminiature overvoltage circuit protection device in a surface mountable configuration for use in printed circuit board or thick film hybrid circuit technology. The surface mountable device (SMD) is designed to protect against electrostatic discharge (ESD) damage to electronic components. The circuit protection device comprises three material subassemblies. The first subassembly generally includes a substrate carrier, electrodes, and terminal pads for connecting the protection device 60 to a PC board. The second subassembly includes a voltage variable polymer material with non-linear resistance characteristics and the third subassembly includes a cover coat for protecting other elements of the circuit protection device. The devices of the present invention employ various electrode configurations and profiles to control the electrical field created between the electrodes and increase the active area of the electrodes in contact with the voltage variable material to enhance the electrical characteristics of the device.
