  • Publication number: 20020167164
    Abstract: A quick-disconnect sill cock flange for allowing the ease of installation and removal of a sill cock (3), having a nipple cartridge body (4) communicating with said sill cock (3) by means of ½″ male iron pipe threads (5), the said nipple cartridge body (4) is hollow and cast with a hex channel (20) the entire length and is fashioned with two o-ring grooves (6), which retain o-rings (8) in a confined address in relation to the interior of a termination flange (9), providing a water tight seal. A termination flange (9) is soldered onto copper tubing (13), to be flush with exterior of building wall. The said copper tubing (13), as well as the said termination flange (9), are secured permanently to the building water system and become absolutely stationary. The said sill cock (3), being attached to the said nipple cartridge body (4), communicates with said termination flange (9), allowing the said sill cock (3), to be drawn up tight by use of a pair of retaining bolts (12) and flat washers (11).

  • Patent number: 6137084
    Abstract: A heated windshield wiper unit having an improved electrical heating element. The wiper may be constructed as a wiper blade constructed of silicon material for attachment to existing wiper blade frame supports that are already standard for automobiles and other vehicles. Inside a hollow core of the wiper there is a nickel-chromium alloy resistive wire with a polyimide insulative sheath for generating heat to melt the ice and snow. Copper leads are connected to the resistive wire by means of silicon sheath. The leads from the wiper blade are connected to the electrical system of the vehicle for after market use.
