  • Patent number: 5386185
    Abstract: An apparatus comprising, in combination, an AC motor, a solid state switch controlling the AC motor, the solid state switch switchable between an on state in which an electric current flows through the solid state switch and an off state in which electric current does not flow through the solid state switch, the solid state switch characterized by a turn off time such that, when the solid state switch is switched between the on state and the off state, at least a portion of the electric current flows through the solid state switch during the turn off time, a first switch circuit for switching off the solid state switch to prevent the electric current from flowing to the AC motor, a diode bridge coupled across the AC motor, a second switch circuit for controllably switching the diode bridge between an active state in which electric current may flow through the diode bridge and an inactive state in which electric current may not flow through the diode bridge, a control circuit for controlling the second switch

  • Patent number: 4684765
    Abstract: An electrical connector assembly includes a bus assembly which comprises a bus insulation plate having a base which includes a plurality of terminal stations and a plurality of guide stations. The terminal stations and guide stations are separated from each other so as to provide a network of wire channels which communicate with wire passages which extend through the terminal and guide stations. The terminal stations also have terminal cavities which extends through the base to intersect the wire passages. The bus assembly further includes electrical busses comprising lengths of electrically conductive wire which pass through various terminal and guide stations via the network of wire channels.
