Abstract: A cordless tool which includes a glue gun function and may include other functions includes a sleeve for receiving a stick of hot melt glue for sliding through the sleeve and a tip at the forward end of the sleeve for discharging the glue when melted. A butane heated gas burner heats the sleeve using gas permeable catalytic heater which surrounds or lies in intimate contact with the sleeve to communicate heat to the sleeve. The arrangement can be modified by closing off the catalytic heater for use to provide multi function.

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: A hand gas torch which includes a fuel gas tank having a gas outlet, gas flow rate control valve assembly mounted in the gas outlet of the fuel gas tank and controlled by a gas lever to open a fuel gas passage, a casing fastened to the fuel gas tank around the gas outlet, a flame nozzle assembly fastened to the casing at which fuel gas and air mixture is burned, a fuel gas nozzle assembly connected between the flame nozzle assembly and the gas flow rate control valve assembly, a piezoelectric device mounted in the casing and controlled to produce sparks at the flame nozzle assembly for burning fuel gas and air mixture, a press button depressed to trigger the piezoelectric device and to drive the gas lever in opening the gas flow rate control valve assembly, a rotary cap controlled to lock/unlock the press button, and a switch controlled to hold the gas flow rate control valve assembly in an open status.

Abstract: A gas torch having a body provided with a connected socket to install a gas-can thereof. A control device is connected to top of the body to control the supply and shutoff of the gas flow. The body is connected with a regulating device to ensure a complete vaporization of liquefied gas and keep the gas pressure constantly. The gas is directed to an injected orifice via a preset route within the body. The injected gas is well mixed within a burning nozzle and ignited by piezo electricity device. Those described components are enclosed by a housing. A branching rod and a baking tube such that the gas torch can be served as a baking device. The burning nozzle can be readily replaced with another type and different flame patterns can be attained.

Abstract: A fuel gas press control device of a gas torch, including a switch mounted on the shell of the gas torch and moved between a circular hole and a sliding slot, a retaining knob mounted in a hole in the switch, a pressure rod fastened to the switch and forced by it to press on the gas lever of a butane well, and a spring mounted around the retaining knob and stopped between a collar of the retaining knob and a horizontal projecting plate of the switch, the spring forcing the collar of the retaining knob into the circular hole of the shell to lock the switch is the operative position when the switch is moved to the circular hole of the shell to force the pressure rod into engagement with the gas lever of the butane well.

Abstract: A burner including a storage tank, a gas outflow means, a pressure regulating means, a control means, a hood, a selectively replaceable gas ejecting base, a gas diffusion burner head and/or a firing means. When in use, a control knob is firstly turned so that fuel gas flows along a gas path to escape from the gas diffusion burner head and/or the firing means. Then a push-button is pressed so that a piezo-electric device generates electrostatic sparks to ignite fuel gas escaped from the gas diffusion burner head and/or the firing means. The intensity of the fire may be adjusted by means of the control means. A handle is also provided to facilitate carrying.

Abstract: An improved heating torch including a barrel, a top mounting, a gas release device, a flame device and a casing unit. After assembly, by turning a switch button, the flow of fuel gas and initiation of a piezoelectric device to start ignition may be controlled. Two copper sheets which retain a regulating sponge therebetween regulate the pressure of fuel gas for maintaining a stable pressure. The reciprocating movement of a control core conceals or opens a connecting hole for regulating gas flow. A ring notch and a corresponding air vent controls the mixture of air and fuel gas. A front end of the heating torch may further be provided with a soldering-iron, and a base plate is provided on the bottom of the barrel for keeping the torch in a stable position.

Abstract: A gas combustion method and apparatus for performing such comprises supplying a fuel gas, generating a gas mixture composed of the fuel gas and external air, diffusing the gas mixture through a diffusion member to lower a flow velocity of thereof, putting the gas mixture to flaming combustion in a cylindrical combustion chamber thereby elevating the temperature of a combustion catalyst disposed to the downstream end of the combustion chamber by the heat of the flaming combustion, then ceasing the diffusion of the gas mixture to increase the flow velocity thereof in the combustion chamber, thereby extinguishing the combustion flame and directly supplying the gas mixture to the combustion catalyst. The gas mixture is put into and out of diffusion by an actuating mechanism that brings a diffusion member into and away from the entrance of the combustion chamber.

Abstract: A fuel combustion apparatus having means for eliminating liquid fuel emissions at the combustion zone. The apparatus can be used as a open-flame torch, or alternatively it can be used as a soldering tool. The nozzle for an open-flame application, and the soldering tip assembly are readily interchangeable. The device is lightweight, portable, and refillable. Dual, finned radiators and an insulator prevent heat from being transferred from the combustion zone to the body of the fuel combustion apparatus.

Abstract: A heat processing device using a liquefied gas comprises a nozzle for jetting a liquefied gas, a gas mixture generating member disposed at the exit of the nozzle for sucking external air through an external air intake port under the ejector effect of the gas jetted out from the nozzle to form a gas mixture, a fire nozzle member for jetting out the thus formed gas mixture to take place flaming combustion, and an air flow control member for controlling the flow rate of air flowing through the air intake port into the gas mixture generating member. The heat processing device further comprises an iron tip member having a combustion catalyst detachably disposed near the top end of the fire nozzle, in which the air intake port in the fully opened state is once closed fully and then fully opened again by the operation of the air flow rate control member interlocking with the operation of the shutter member for closing/opening the space between the fire nozzle and the combustion catalyst.
