Abstract: A torch suitable for use in recreational applications, such as with patios or decks, includes a gas cylinder, a holder for the cylinder, a pole to support the holder and a burner for producing a stable, visible flame. The burner includes one or more holes for injecting primary air near a flow-controlled gas orifice and a burn tip spaced from the orifice. A bowl is mounted about the burn tip and is preferably shaped for providing wind resistance and admitting secondary air at its exit to produce a stable, visible flame. In the preferred embodiment, the enclosure is made from plastic, and has a socket for receiving the pole. An oil, such as citronella oil, may be mixed with the propane or other gas in the cylinder to scent the area in which the torch is used.

Abstract: A automatic ignition gas lantern includes baffle positioned near the outside of a mantle, so that gas flowing out of the mantle will be disturbed by the baffle. This sets up a region with a fuel/air mixture that can be easily and reliably ignited. A spark is then generated in this region, which ignites the gas and causes the mantle to glow brightly.

Abstract: A remote lighted wick extinguisher that uses a movement of air to extinguish the flame of a lighted wick. Energy is sent from a transmitter to a remote receiver. The receiver actuates a circuit, such as a mono-stable multivibrator or one shot producing a pulse. The pulse, having sufficient amplitude and duration, actuates a transducer, similar to a speaker. The pulse causes a diaphragm of the transducer to displace, thus displacing a volume of air. When the transducer is disposed in close proximity as the lighted wick, the displaced air is able to extinguish the flame of the lighted wick. Thus, a user is able to extinguish the flame of a lighted wick lamp remotely from a distance.

Abstract: A safety device in a lighting rod comprises a locking member having an engagement section, which interferes with a portion of an operation member and thereby locks the lighting operation of the operation member. The locking member can move in a direction, that intersects with the direction along which the operation member moves. An urging member urges the locking member to a locking direction. The locking member is provided with a lock releasing section, which can be operated in order to move the locking member in a direction, that acts against the urging force of the urging member. The lock releasing section is projected to a position, which stands facing the operating section of the operation member. The lock of the lighting operation is released by operating the lock releasing section of the locking member, and the lighting operation is carried out in this state by operating the operating section of the operation member.

Abstract: A compound solar water heating and dehumidifying device including an adsorption bed disposed at a lower rim of a plate type heat collector of a solar water heating element for causing a heat collector element to absorb heat in the day-time and the adsorption bed to regenerate and accumulate heat. At night, the heat of adsorption and heat of condensation are released to the heat collector element to retard the drop of temperature of water in water channels that are in contact with the heat collector element. Therefore, dissipation of heat from the hot water in a water tank may be retarded and water moisture may be removed.

Abstract: A solar collector consists of extruded hollow metal sections in two layers joined together by parallel longitudinal webs, in which the open ends of the hollow sections are connected together in such a way that the heat carrier flows sinuously through said sections.

Abstract: A gaseous fuel (B) is fed to a a premixing burner which has a main line (10) for the feed of oxygenous gas (G) into at least one mixing zone and/or a combustion zone (VMZ, EMZ, VZ). In the process, at least a first portion of the fuel is fed to the main line (10), in which it is mixed with oxygenous primary gas (PG) inside at least one premixing zone (VMZ) and forms a premixture. The concentration of the fuel in the premixture (VM), under the respective operating conditions of the burner, is selected in such a way that the premixture lies outside the ignition limit. The premixture (VM) is fed to a final mixing zone (EMZ) and is mixed therein with the residual fuel (RB) likewise supplied and/or with oxygenous secondary gas (SG). The resulting final mixture (EM) is fed to a following combustion zone (VZ).
