  • Patent number: 7002789
    Abstract: A capacitor assembly is formed from one or more capacitive elements placed between a pair of opposing brackets. Each bracket has at least one L-shaped section and an arcuate section. Each L-shaped section has a capacitor seating surface and an assembly connecting surface that is substantially perpendicular to the capacitor seating surface. The arcuate section is adjacent to the capacitor seating surface. The opposing ends of each capacitive element is in electrically contact with the capacitor seating surfaces on the opposing brackets. When secured to a bus bar by fasteners located in the regions formed by the arcuate sections of the opposing brackets the assembly connection surfaces serve as electrical and thermal conducting regions between the capacitor assembly and the bus bars. Alternatively a capacitor assembly may be secured to bus bars by fastening to the capacitor seating surfaces.

  • Patent number: 5306054
    Abstract: A brittle thermoplastic molded cylindrical hollow hole seal has a top wall and a depending side wall. An annular external rib snap fits to an annular groove in a hole side wall to secure the seal in place. Axially extending angularly shaped in cross section grooves are on the side wall interior and spaced axially extending slots pass through the side wall. The top wall internally has an eight point star shaped set of ridges and troughs whose points terminate at the side wall forming the interior grooves. Reflective aluminum flakes are in the material to provide a spotty finish. The slots, grooves, ridges and troughs form weakening regions causing the seal to shatter in response to an applied local pressure, for example, exerted by a screw driver for use with a screw plugged by the seal. The spotty appearance is difficult to hide when the seal is broken.
