  • Patent number: 7806736
    Abstract: A terminal of a wiring device includes a conductive plate, an arm, and a wire guide. The conductive plate has an opening formed therethrough. The conductive plate receives a fastener for securing a substantially straight wire to the conductive plate. The arm extends from the conductive plate and defines a mating element on the wiring device. The arm is an anchor of said conductive plate. The mating element of the arm is adapted to cooperate with a complementary mating element. The wire guide is in spaced relation to the fastener to position the substantially straight wire adjacent to the fastener.

  • Patent number: 7175485
    Abstract: An improved clamp that can be inserted into a wiring device independent of a wiring termination assembly thereby reducing the complexity and cost of the manufacture of the wiring device. The clamp has a pair of legs spaced apart forming an opening to allow the wiring termination assembly to be inserted therebetween. The wiring device includes support members to support the clamp legs so to permit the clamp to pivot about the support member independently of the wiring termination assembly.

  • Patent number: 4304745
    Abstract: Multi-colored detergent bars can be manufactured by extruding detergent material through a multi-apertured plate in a detergent plodder and injecting a visually distinctive liquid at the plate. The liquid is distributed throughout the detergent material in the form of striations as the material is compressed in the extrusion cone.A specific form of external striping and the use of increased amounts of injected liquid can be achieved by having some of the apertures positioned peripherally on the plate. These apertures form `walls` of extruded material which constrain the liquid into stripes.The manufactured bar has a distinctive appearance because the external striations are wider than the internal striations.
