Abstract: An appliance for burning a combustible gas, for example a liquefied petroleum gas. The appliance includes a relatively massive metal body forming a heat sink, in which there is formed a passage for flow of the combustible gas from a feed inlet to a discharge outlet. A control member controls the flow rate of the combustible gas.

A burner burns the mixture to be burned, and is in thermal connection with the metal body. The control member includes a pressure reducer, at least partially incorporated into the metal body. The pressure reducer includes a chamber into which the combustible gas is admitted in a liquid phase at high pressure, and a chamber from which the gas is discharged at low pressure, at least partially in the gaseous phase. The chambers are formed in the metal body.

Abstract: A collapsible fuel-burning stove includes a burner assembly and a collapsible frame for supporting the burner assembly, the frame including a plurality of support members, the support members being pivotal relative to one another about a common axis on which the burner assembly is supported.

Abstract: A connector is provided for securing a conduit to a fluid source, which source includes a noncircular cylindrical pedestal having a fluid source outlet extending therethrough and an annular groove surrounding the pedestal. The connector includes an inlet port engageable with the fluid source outlet and an outlet port in fluid communication with the inlet port and engageable with the conduit. A collet includes a base, and a plurality of fingers extending from the base substantially parallel to an axis of the inlet port, each finger being disposed a common radial distance from the axis of the inlet port and including a radially extending pawl spaced from the base. An annular cam has a noncircular cylindrical receptacle correspondingly engageable with the noncircular cylindrical pedestal of the fluid source and having an axis coincident with the axis of the inlet port.

Abstract: An LPG canister connector for a combustion appliance having a flow path from a canister containing liquid fuel and having a cap with outlet means at the upstream end of the flow path, a valve assembly adapted to be connected to the cap and equipped with a conduit adapted to be connected to a combustion appliance at the downstream end of the flow path, and promoters for vaporization of said fuel being located intermediate the ends of the flow path.

Abstract: A lantern includes an elongated tubular mantle which is attached to a burner assembly by a spring clip and an electronic ignitor for igniting fuel which flows into the mantle. The mantle is surrounded by a globe, and a wire guard surrounds the globe. A ventilator cap is removably attached to the burner assembly and to the wire guard so that the cap, wire guard, and globe can be removed as a unit from the burner assembly. A nut is rotatably captured on the ventilator cap for attaching the ventilator cap to the burner assembly. The fuel tank includes a wide, molded base which provides stable support. An air pump for the fuel tank includes a check valve which automatically opens and closes as air is pumped and a pressure indicator to indicate when the fuel tank reaches operating pressure. The pump is automatically lubricated on each stroke.

Abstract: Apparatus and methods for fluxing with water-soluble flux. A circuit card assembly has its solderable surface exposed for fluxing. A spray nozzle atomizes the flux to provide a mist that wets the surface without creating flux droplets. A pump is coupled between the spray nozzle and a container which stores the flux for pumping flux and atomizing the flux to create the flux spray. The apparatus may be used as a stand alone fluxing station for use with a liquid wave solder or vapor solder system. Alternatively, the apparatus may be used as an integral part of a wave soldering system that replaces the conventional fluxing station. In this embodiment, the apparatus is located beneath the conveyor and a sensor is used to actuate the flux spray. A plurality of nozzles or pluralities of sets of nozzles may be employed to achieve proper wetting of the assembly.
