Abstract: The present invention relates to a portable heat transfer apparatus designed to supply heat to an external heat load, such as a space-heating unit or a heating garment, in a manner to be usable in outdoor and other environments where it is difficult to receive a supply of electricity or fuel gas, and allows a ratio of LPG and air to be controlled so as to perform combustion in desirable conditions.

Abstract: A heating cooker including a cooker body having a cooking chamber and a convection heating unit. The convection heating unit includes a convection heater to generate heat, a convection fan to forcibly move the heat generated from the convection heater into the cooking chamber, a convection motor to drive the convection fan, and a convection housing to receive the convection heater and the convection fan. The convection heater and the convection fan are linearly arranged within the convection housing, to allow air introduced into the convection housing to move from the convection fan to the convection heater. This configuration is effective to restrict the transfer of heat from the convection heater to the convection motor.

Abstract: The present invention generally provides a system for warming an outdoor surface. The system includes a heat exchange unit to provide heated air for use across the surface to melt snow or ice or to warm, evaporate or distribute water. The heat exchange unit is used to recapture the heated air. The present invention also generally provides a method of warming an outdoor surface. The method comprises the steps of providing heated air across the surface to melt snow or ice or to warm, evaporate or distribute water, recapturing the heated air, and redistributing the heated air across the surface.

Abstract: Vacuum processing equipment capable of preventing particles from sticking to objects to be processed in vacuum vessels. The vacuum equipment comprises a series of vacuum vessels separated by doors, and the pressure in the vessels are reducible respectively. The vessels are so configured that objects to be processed are movable among them, and there is provided light projection means for projecting ultra rays on gases introduced to at least of the vessels.

Abstract: A tool for soldering pin-in-hole electronic circuit components includes a tool plate with a set of via holes corresponding to the holes of a circuit board on which a circuit component is soldered. The board is aligned with the tool plate and hot gas is supplied through the set of plate vias to reflow solder in the board holes. The tool is particularly suitable for use in removing and replacing pinned circuit components. Use of particular gases (e.g., nitrogen) allows soldering to be carried out without the use of flux. Advantages of the tool are that it prevents burning the circuit board and/or unintentionally reflowing other circuit components mounted on the board (by directing hot gas only substantially onto the circuit board's solder-containing holes).

Abstract: A mobile fossil fuel heating device allows almost any indoor or outdoor area to be heated with radiant heat. A radiant tube gas burning heater is mounted on a wheeled carriage for rotation about a horizontal axis so that the radiating face of the heater may be positioned in a desired orientation. Once positioned, the heater is held in that position by a clamp arrangement. The fossil fuel for powering the heater may comprise a number of propane tanks mounted on the carriage, and shielded from the heater by infrared shields. Hollow shafts mount the heater for rotation, and a fuel conduit, and an electrical wire, pass through one of the shafts to supply fuel and power to the heater while not interfering with the rotation of the heater.

Abstract: An engine heater for airplanes or automobiles burning propane gas to heat the engine. The heater employs electrical power to control the combustion of the propane gas and to propel the heated combustion products toward the engine. The unit may utilize a building's usual line current of 115 volts a.c.; it may also rectify this a.c. voltage to provide d.c. power capable of charging the battery on the vehicle. In the absence of the 115 V. a.c., the heater may simply connect to its own battery or the battery of the airplane or the automobile in order to warm the vehicle's engine and battery to facilitate the commencement of the vehicle's operation. The heater unit includes connections to the appropriate source of power for the heater's operation. When connecting the 115 volts a.c. source, it transforms the voltage to the appropriate magnitude to operate the heater. The unit may also include a gas pilot light, an ignition coil for the pilot light, and two electrically controlled valves.
