Abstract: A hot air generator comprising a handle (12), an elongated nozzle (14), flame generating means (6), a venturi (4), a gas conduit (162) intended to bring a combustible gas into the elongated nozzle (14) and at the flame generating means (6), an air conduit (164) intended for bringing compressed air into the elongated nozzle (14) and downstream from the venturi; characterized in that the generator further comprises a servocontrolled pressure regulator (2) controlling a gas pressure (Pd.g) in the gas conduit (162) depending on an air pressure (Pd.a) in the air conduit (164).

Abstract: A variable wood burning tool for burning woods at varying temperatures and providing alternate uses essentially comprised of a container and a lid hingedly secured thereto. An interior surface of the lid has a heat resistant tray disposed therein. A heating element is disposed within the container. A burning wand is operatively coupled with the heating element. A plurality of tips are provided that are each adapted for removably coupling with the burning wand.

Abstract: A gas lighter includes a handgrip holding a fuel tank and an electric arc generator, an actuating device pivoted to the inside of the handgrip, an ignition button mounted in an opening on the handgrip and adapted to trigger the electric arc generator in producing an electric arc for burning fuel gas discharged out of a gas nozzle in a cylindrical metal casing at one end of the handgrip and simultaneously to drive the actuating device in opening the fuel tank for enabling fuel gas to flow out of the fuel tank to the gas nozzle for burning, and a spring-supported locking lever assembly mounted in a sector slot on the handgrip and adapted to move the actuating device between the operative position and the non-operative position.

Abstract: A gas lighter comprises a housing for receiving a fuel reservoir and a pivot plate, a spring-biased ignition button partially raised above the housing with bottom in contact with the pivot plate having a conductive contact, a spring-biased safety button partially raised below the housing, a high-voltage circuit device including a first contact coupled to ignition tube, a second contact coupled to a source, and a conductive pad coupled between the second contact and the stud. In use, depress the ignition button and the first safety button to form an electrical path from the source to the ignition tube for generating an arc, and the pivot plate is pivoted by the ignition button to open a gas outlet to introduce gas to the ignition tube for igniting the gas lighter.

Abstract: A jet pump for a heat gun includes an elongate hollow pump body lying along a longitudinal axis. The pump body has an inlet, a mixing section and an outlet. A nozzle unit is axially aligned with the inlet for directing pressurized fuel into the inlet of the pump body. Movement of the pressurized fuel into the inlet causes air to be drawn into the inlet to mix with the fuel within the pump body. A disk shaped air diverter is axially spaced away from the inlet of the pump body. The diverter has a length and a diameter. The diameter of the diverter is greater than the length of the diverter and larger than the inlet of the pump body. A housing is radially spaced from and surrounds the diverter forming a first annular gap therearound for air outside the housing to pass therethrough. The air moves around the diverter then changes direction between the diverter and the inlet of the pump body before entering the inlet.

Abstract: An electronic ignition gun includes a casing holding a fuel gas container, a battery and a high voltage circuit on the inside, the fuel gas container having a gas outlet valve and a pull tab coupled to the gas outlet valve, a push-button switch mounted in a hole on the casing and depressed to drive the pull tab in opening the gas outlet valve for letting fuel gas be discharged out of the fuel gas container through a gas nozzle via a gas tube and to simultaneously close the circuit between the high voltage circuit and the battery, causing the high voltage circuit to discharge a high voltage in producing sparks for igniting discharged fuel gas, and safety lock means, which stops the push-button switch from operation.

Abstract: A handheld soldering tool has a fuel reservoir or tank (10), a tip (1) heated in use by a catalyst assembly (2), a valve assembly (9) for controlling flow of gaseous fuel from the reservoir (10) to the catalyst assembly (2), and a piezo-electric ignition device (7) for igniting gas released from tank (10) for combustion during an initial warm-up period to bring the catalyst to its operating temperature. A spring member (19) mounted on a rocker member (17) serving to transmit an actuating force from a switch member (18) to the piezo device (7) is arranged to momentarily interrupt the flow of gas from valve assembly (9) through Venturi (16) to combustion region (15), to terminate the initial combustion period, during reverse movement of the rocker member (17) from an ignition disposition to a non-active or gas-flow disposition.

Abstract: An electronic ignition gun including a housing holding a gas lighter and a high voltage inductor, a press control switch pivoted to the housing and partially projecting out of an opening in the housing for operation with a hand to release the gas valve of the gas lighter and to trigger the high voltage inductor, the press control switch having a front projection adapted for triggering the high voltage inductor in inducing a high voltage for producing sparks for burning fuel gas, an arched rear side wall, and a bottom opening extended to a part of the arched rear side wall, and a gas lever balanced on a part of the gas lighter and having a notched coupling portion at one end coupled to the gas valve, an arched actuating face at an opposite end disposed in contact with the arched rear side wall of the press control switch, and a projecting block raised from one end of the arched actuating face and inserted into the bottom opening of the press control switch to guide the movement of the gas lever relative to the
