  • Patent number: 4946599
    Abstract: Apparatus and methods for converting a bottled water dispenser for use with a continuous source of water are disclosed. In a preferred embodiment, means for reducing the pressure and filtering the continuous source of water are provided. In a most preferred embodiment, the apparatus is configured to substantially reside within the existing dispenser apparatus, thus eliminating the need for bottled water. A housing is provided which contains a filter in an upper portion thereof, the lower portion shaped to conform to an existing tank within the bottled water dispenser in order to provide good thermal communication between the apparatus of the present invention and the existing refrigeration means. Chilled water is retained in the lower portion of the housing and is filtered upon demand, thus providing freshly filtered water to the user at a pressure and velocity substantially the same as that produced using a bottled source, without the contaminants expense and inconvenience associated with bottled water.

  • Patent number: 4095591
    Abstract: An extension is provided for being nonrotatably fixed to a lag screw that is to be anchored to the head of a femur or other bone in a manner so as to allow compression to be applied to a fracture. The extension extends outward of the bone when attached to the lag screw and when the lag screw is anchored to the bone to allow a compression plate to be easily positioned thereon. The cross-section of the extension is substantially the same as the cross-section of the lag screw to allow the compression plate to be easily and quickly passed onto the lag screw from the extension once the compression plate has been positioned on the extension.
