Abstract: A new and useful improvement in sterile thermometer sheaths. The improved sheath may be constructed by providing a weakened area in the laminated cover of the sheath immediately adjacent the closed end of the sheath. In use the cover is slid backwards in an accordian-like fashion along the length of said sheath thereby exposing said sheath through the weakened cover area for use in taking a patient's temperature and the contaminated sheath may be recovered before disposal.

Abstract: An energy saving device that utilizes the rejected heat from an air conditioning unit for heating water or other suitable liquid in a conventional liquid heating storage tank. The primary heater control in the storage tank is turned off whenever the air conditioning compressor is operating by a pressure sensing switch in the compressor line that is wired in series with the tank heater control circuit. A water circulating pump is used to pass relatively cold tank water through a heat exchanger which is connected to the compressor outlet conduit of the air conditioner. The pump is controlled by a thermostatic switch which measures heat exchanger outlet water temperature. The device not only utilizes otherwise rejected heat energy from an air conditioning unit for heating water in a conventional hot water tank but also increases the efficiency and endurance of the air conditioning system by removing super heat from the compressor gases.

Abstract: An article which may be placed at a point between the water pipe inflow line and a shower head to reduce the inflow of water to the shower head. More particularily a disc shaped article having a hole in its center and being concaved inward from its outer circumference to the center hole. The size and shape of said article being such that it is adaptable to a multiplicity of different size and shape shower heads.
