  • Patent number: 5819837
    Abstract: Metal is melted in an induction-heated crucible (13) on which a mold (10) with a downward-facing filling opening (26) is located in the melting position. After melting the metal, the crucible (13) and the mold (10) are jointly rotated about a horizontal axis (A--A) into a tilting position in which the molten material flows from the crucible (13) into the mold (10). In order to melt reactive metals, melting is done in a crucible (13) that is surrounded by a vacuum, this crucible being surrounded by an induction coil (15) outside of the vacuum. The mold (10) is located in a vacuum-sealed casting chamber (6) which is evacuated together with the crucible (13) prior to melting and casting is carried out by a joint tilting of the crucible (13), casting chamber (6) and mold (10) by at least 180 degrees while the vacuum is maintained.

  • Patent number: 5746626
    Abstract: An electrical connector assembly facilitates the establishment of an electrical connection with a terminal on an electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a first orientation relative to the component, and for inhibiting the establishment of an electrical connection with the terminal on the electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a second orientation relative to the component, opposite the first direction.

  • Patent number: 5685035
    Abstract: An adjustable bed includes a mattress frame having pivotally interconnected sections, a main or base frame supporting the matress frame and telescoping leg assemblies. A first motor drive actuator is supported on the main frame. The first actuator engages a crank arm or lever fixed to a head section of the mattress frame. A second actuator is mounted on the base frame. A second actuator engages a crank arm attached to a knee section of the mattress frame when the actuator is moving to a fully retracted position. A cable carrier is engaged by the second actuator as it moves to a fully extended position. A cable assembly interconnects the cable carrier with the telescoping leg assemblies. The second and moves the mattress frame between low and high positions.
