Abstract: A removable and collapsible barricade post assembly for the restriction of vehicular traffic. The barricade post assembly has a novel base assembly that allow the post assembly to be removed from its mounting bracket which is normally permanently affixed to the ground. Alternatively, the post assembly can remain attached to its mounting bracket while being lowered to allow the passage of vehicular traffic. The barricade post assembly has a number of security features to restrict the unauthorized removal or collapsing of the barricade post. A cover assembly to enhance security and to provide weather protection for the barricade post assembly is also described.

Abstract: The present invention is an improved filter assembly for providing at least common-mode filtering.

First and second coupling devices are coupled electrically to respective first and second electrodes of each multiple layer capacitor of the plurality of multiple layer capacitors. A clamping devices clamps the first and second coupling devices, the plurality of multiple layer capacitors, and an electrically insulating layer to a mounting surface so that the electrically insulating layer is between the first coupling devices and the mounting surface and so that the plurality of multiple layer capacitors are electrically connected in parallel between the first and second coupling devices.

Abstract: A power semiconductor assembly, particularly a semiconductor switch assembly which has a number of discrete emitter connection pads, comprised of a metal matrix composite housing and a copper or aluminum post with a cross-sectional area sufficiently large to carry the rated current providing a single-point, external connection to all emitter pads. The post passes through and is supported by an insulating ceramic insert such as aluminum oxide in the wall of the metal matrix composite housing. The post is hollowed out in the region where it passes through the ceramic insert in order to reduce the mechanical stress between the post and the insulating insert as a result of the mismatch in their thermal expansion coefficients. Buses on either side of the semiconductor die provide surfaces for connection from the post to the discrete emitter connection pads on the die.

Abstract: A package for a high power electrical component includes a base and a plate disposed on a support surface of the base and having an electrically insulative layer and an outer layer having a conductive portion thereon. An electrically conductive pad is disposed on the electrically conductive portion of the plate and the electrical component is disposed on the pad. A cover is disposed atop the base and encloses the plate, the pad and the electrical component. First and second electrically conductive terminals extend through apertures in the cover and are electrically coupled to the electrodes of the electrical component. The cover is hermetically sealed to the base and to the first and second terminals. The coefficient of thermal expansion of the base and cover are substantially equal to minimize stresses developed therein.

Abstract: The problem of preloading a rotor assembly (14) in a dynamoelectric machine (10) of the permanent magnet type is solved by providing a hub (20) having a plurality of outwardly opening, annularly spaced slots (22, 24). The slots are outwardly converging and separated by outwardly diverging partition portions (26) of the hub. A plurality of outwardly converging permanent magnets (30) respectively are disposed in the slots. A containment shell (32) surrounds the hub. Wedges (36) are inserted between the base of each permanent magnet and the bottom (24) of its respective slot for loading the permanent magnets radially outwardly toward the containment shell and against the sides of the slots, thereby to place the partition portions of the hub under tension in a static condition of the rotor assembly.
