  • Patent number: 6248663
    Abstract: An electrical data distribution system includes a housing with two end surfaces and at least six low profile side surfaces. The two end surfaces have an absence of connector cut-outs, and each of the side surfaces has at least one connector cut-out. At least one multi-pin electrical feed connector is disposed within a corresponding one of the cut-outs in a corresponding one of the side surfaces. Each feed connector is configured for connection with a multi-conductor data feed cable. A plurality of multi-pin electrical break-out connectors are associated with a plurality of the side surfaces. Each pin in each break-out connector is electrically connected with one of the pins in a corresponding feed connector. Each break-out connector is disposed within a corresponding one of the cut-outs. The break-out connectors are disposed on different side surfaces than each feed connector. Each break-out connectors is configured for connection with a workstation.

  • Patent number: 6223550
    Abstract: An ice maker includes a mold and an auger. The mold has at least one cavity with a bottom surface, and is configured for containing water therein for freezing into ice. The auger has a shaft with at least one flight attached thereto, the shaft including a top end and a base end with the base end being rotatably mounted in the bottom surface of the at least one mold cavity. The shaft extends substantially vertically through the mold cavity and is configured to rotate and thereby push the ice out of the mold cavity. The shaft and/or at least one flight has an inward taper in a direction heading from the base end to the top end of the shaft.

  • Patent number: 6104866
    Abstract: An electrically heated chemical delivery system which is connectable with an electrical receptacle includes a housing with at least one opening therein. A heat actuated chemical pouch is disposed within the housing adjacent to at least one of the openings. A printed circuit board is disposed within and carried by the housing. The board carries a plurality of electrical components thereon, including at least one heater and a light. The board has at least two electrical contacts connected with the electrical components and positioned on an edge thereof. A base is attached with the housing. At least two electrical conductors are carried by the base. Each electrical conductor includes a first terminal end extending from an exterior of the base and a second terminal end engaged with a respective one of the electrical contacts. The first terminal ends are connectable with the electrical receptacle.
