  • Patent number: 5544371
    Abstract: A support frame is positioned over a hospital bed to assist in lifting and turning a patient on a sheet. The patient can also be lifted from the bed, the frame narrowed, and the patient transported to other locations in the hospital and then back to the bed without any severe physical handling.

  • Patent number: 5179998
    Abstract: A heat recovery ventilating dehumidifier provides fresh, cool, low relative humidity air to a building or room during warm weather, and warm fresh air during cold weather. Fresh air is drawn into the heat recovery ventilating dehumidifier, cooled and dehumidified by heat exchange by exhausting stale air in a first heat exchanger, then further cooled and dehumidified by passage through a refrigerant coil. After passage through the refrigerant coil the fresh cool air passes through a second heat exchanger, cooling exhausting stale air and in exchange becoming less cool to reduce the relative humidity. The cool, fresh air having a lowered relative humidity is then used to ventilate a building or room. The cooled exhausting stale air then passes through the first heat exchanger cooling the fresh warm incoming air. In the winter time the refrigerant coil is replaced by a heater and heat is recovered from the exhausting stale air and transferred to the incoming fresh air.

  • Patent number: 4435313
    Abstract: An electrode with an outer coating for effecting an electrolytic process is provided with a protective intermediate coating consisting of a conducting insoluble polymer network formed in situ on a titanium base and containing a small amount of finely dispersed platinum group metal catalyst.A method of manufacturing the electrode comprises applying to the titanium base several layers of a solution containing a polymer precursor and a platinum metal compound which are thermally converted to the protective polymer coating, on which the outer coating is formed, more particularly by electrodepositing manganese dioxide or lead dioxide.The polymeric intermediate coating serves to protect the titanium base from oxidation, and to more particularly provide stable electrode performance with economical use of precious metal.
