  • Patent number: 4859249
    Abstract: Cleaning process for removing material coated on the inner surface of an enclosed vessel. e.g., photographic emulsion, photopolymer, subbing layer, chemicals, etc., comprisingA. forming a substantially continuous high pressure stream of cleaning liquid, e.g., water, solvent,B. supplying the stream of liquid at a pressure, 4000 to 8000 psi to at least one fixed point in the vessel,C. dividing the stream into at least two opposed paths, andD. directing the liquid onto said surfaces in a 360.degree. solid angle using the fixed point as the angle vertex.The process is particularly useful in cleaning photographic emulsions but is also useful in removing other chemical materials and chemicals from an enclosed vessel.

  • Patent number: 4856984
    Abstract: Automatic reset for an unattended gas furnace has an induced draft blower motor energized by an electrical power source and with a first, normally "open", relay switch in circuit to control the operation of the blower motor. A burner control circuit, energized by a transformer coupled portion of the power source, has a room thermostatic switch, a second, normally "open", relay switch in series with the thermostatic switch and an air-flow switch operated by airflow in the furnace to connect the control circuit to the second power source when the blower is "on" and the thermostat is "closed", calling for heat. The second switch is connected to the control electrode of an electronic switching element to energize selectively a relay controller which, when energized, closes both the first and second relay switches to energize the blower motor and burner control circuit.

  • Patent number: 4856392
    Abstract: The invention involves moving a strip of electroluminescent material past a shear in successive increments each equal to the length of a lamp outline to be cut from the strip. The shear is actuated after each incremental advance to cut a blank having a first dimension equal to the desired length of the lamp outline and a second dimension equal to the strip width, which is a multiple of the desired width of the lamp outline. The blank is then advanced past a punch and die in successive increments equal to the width of the lamp outline to be cut. The punch is actuated after each incremental advance to cut across or transverse to the second dimension to form lamp outlines having the desired length and width. The punch and die are configured to simultaneously cut a straight side of a lamp outline advanced past the punch and a straight side having a projecting electrical tab of an adjacent lamp outline behind the punch.
