  • Patent number: 5892662
    Abstract: A card rack is provided for removably housing two types of circuit packs in respective first and second portions, e.g., upper and lower portions of the card rack. The card rack includes connectors for interconnecting components on the circuit packs with one another and to input and output cables. The input cables are connected only to circuit packs of one type which are disposed only in one, e.g., the lower, portion of the card rack. The upper card rack portion overhangs the lower card rack portion for, in combination with sides of the card rack, forming a recessed space through which the input cables are routed to the lower portion circuit packs. The passage of the cables through the recessed space isolates the cables from becoming entangled with traffic passing in front of the card rack and thereby avoids the need for a separate door enclosing the front portion of the card rack.

  • Patent number: 5847636
    Abstract: A user adjustable switching controller for duty cycle regulating flow of current to an electrical load such as a resistance heater, particularly for cooking appliances. A load current switch, when closed by a user operated cam also energizes a heat motor which includes a resistive strip attached to one active leg of a U-shaped bi-metal member. The load current switch snap spring is attached to the heated leg of the bi-metal. The other leg of the U-shaped bi-metal is anchored to one of the load connecting stationary terminals and serves to provide ambient temperature compensation. User rotation of the cam deflects a bias spring which acts on the portion of the bi-metal attached to the load switch snap spring to effect closing of the load current switch and energization of the heat motor. Heating of the bi-metal causes warpage which overcomes the bias spring to open the load switch and shut off the heat motor. Cooling of the bi-metal allows the load current switch to re-close repeating the cycle.
