  • Patent number: 4920950
    Abstract: A collapsible camp stove having a frame supporting a grate therein for cooking meat or other food. A pair of end plates attached to the frame by hinges which allow pivotal movement of the end plates between a collapsed and erected position. A latching means locks the end plates in the collapsed or erected positions. The grate is of expanded metal to provide better gripping of the food items. The frame has a handle for convenient carrying of the camp stove when collapsed. The handle may be recessed flush with the frame when not in use. A removable cooking plate is provided which contains one or more apertures for exposing less than all of a pot or pan seated over the aperture or apertures to direct heat of the camp fire while reducing exposure of the cook or sides of the pots or pans from direct exposure to the camp fire. The bottom edges of the end plates opposite the hinges have crescent cutouts to provide four point footing for the camp stove.

  • Patent number: 4899728
    Abstract: Ventilation air for a building is preheated by providing on a south-facing wall a solar-energy absorbent collector panel with a plurality of air-inlet openings which communicate with air collection channels behind the panel. Outside air passing upwardly along the panel is heated by the heat of the panel which itself is heated by a combination of solar radiation and heat being lost from the interior of the building. The outside air, passing upwardly a short distance along the panel to the closest air inlet opening, is withdrawn therethrough into the air collection channel and expelled into the interior of the building.

  • Patent number: 4869662
    Abstract: A flame extinguishing device for use with an ornamental lamp having a base, a chimney, and a wick which provides a lamp flame, includes a plate coupled inside of the chimney below the flame. The plate has a hole in the center thereof surrounding the flame but below the flame. As the plate is lifted above the flame, a low pressure area is formed below the plate. The pressure differential between the bottom of the plate and the top of the plate causes combustion by-products above the flame to flow downward through the hole. As the combustion by-products flow past the flame, oxygen is temporarily prevented from reaching the flame, thus extinguishing it. Therefore, extinguishing the flame is a simple matter of lifting the chimney an inch or so. The plate may include side holes which prevent the flame from being extinguished when the chimney and plate are placed on the lamp when the flame is burning.

  • Patent number: 4869723
    Abstract: A condom is provided for enhancing feeling and stimulation on the part of the male by allowing the condom to move, e.g., by a sliding action on the surface of the penis during intercourse. Typically the distal end of the condom is frictionally related to the vagina by weakly bonding the condom to the vagina as by means of a gum-like adhesive agent or by means of a multiplicity of minute fibers bonded on the outside surface of the condom or both. The condom near its open end is held tightly against the base of the penis and, if desired weakly bonded thereto by means of a removable adhesive to form a tight seal.

  • Patent number: 4865010
    Abstract: An exhaust duct cooling system is provided for a built-in gas oven wherein cool air is drawn into the oven enclosure and through an oven controls area to cool that area, and then the cool air is directed into a cool air duct which is positioned between the oven cooking cavity and an oven exhaust duct to thermally isolate the controls area while cooling the oven exhaust. The cool air duct has a first, lower outlet below the oven controls, and a second, upper outlet adjacent to an outlet of the oven exhaust duct where cool air and oven exhaust are mixed in a chamber prior to exiting the oven cabinet. Thus, the oven exhaust is tempered prior to being exhausted from the front of the oven.

  • Patent number: 4862870
    Abstract: A self-cleaning over door latching mechanism is provided with a locking arrangement responsive to the oven cavity temperature, which includes a locking pin moved by a snap action bimetal member mounted in thermal communication with an oven cavity wall. The bimetal member moves the locking pin to a locking position when the temperature sensed by the bimetal rises above the locking temperature. In its locked position the locking pin prevents the opening of the latch until the temperature in the oven cavity falls below the locking temperature. In its locked position the locking pin also actuates a lock switch electrically connected in parallel with a thermal limit switch. The thermal limit switch provides over temperature protection for the cavity when operating in the normal cooking modes. When actuated, the lock switch shunts the limit switch thereby enabling the temperature in the cavity to rise to the self-clean range.

  • Patent number: 4861261
    Abstract: In order to adapt a gas-infrared radiator (a radiant burner) to operating conditions in a particularly efficient manner, the energy delivered is reduced by intermittently reducing a controlled supply of gas so that the energy delivery is below about 40% or even less of the maximum energy delivery of the infrared radiator, and a flame supplied separately from the controlled gas supply is maintained in the combustion chamber of the gas-infrared radiator, at least when operating in the aforementioned range. This is achieved more particularly by providing at least one nozzle (22) for a pilot light, directed towards the combustion chamber (4).
