Abstract: A gas burner includes a laminate catalytic device mounted thereon. The gas burner includes a nozzle and an igniter installed in the nozzle. The laminate catalytic device is mounted on the nozzle. The laminate catalytic device includes three separated catalytic nets. The gas burner includes two separators for separating the catalytic nets from one another. The separators are in the form of a ring. Each of the catalytic nets helps burn 80% of gas flowing through it. The gas burner includes a shell for retaining the laminate catalytic device on the nozzle. The shell is in the form of a tube in order to receive the laminate catalytic device and the nozzle. The gas burner includes a bolt inserted in an aperture defined in the shell and an aperture defined in the nozzle, thus securing the shell to the nozzle and retaining the laminate catalytic device in position.

Abstract: A cigarette lighter includes a shell, a nozzle, an ignition device, a button, a cap and a linkage. The shell includes a reservoir for fuel. The nozzle is in communication with the reservoir through a pipe. The ignition device includes a wire extending to the vicinity of the nozzle. The button is connected with the ignition device. The button is movable between a locking position, a first operative position and a second operative position. The cap is mounted on the shell for covering the nozzle. The linkage is connected between the button and the cap. The linkage locks the cap in the locking position. The linkage releases the cap in the first operative position. The ignition device creates electric arcs between a free end of the wire and the nozzle in the second operative position.

Abstract: A nail-driving tool includes a cylinder defining a chamber for reciprocatingly receiving a piston. A bumper is received in the chamber and includes a first bumper section and a second bumper section made of a material having a rigidity different from that of the first bumper section. When in a driving stroke of the piston toward the bumper, air in the chamber exits the cylinder via ports of the cylinder.

Abstract: A nail-driving tool includes a body and an illumination device detachably mounted to the body. The body includes a plurality of engaging members formed thereon, and the illumination device includes a casing having an engaging groove for releasably engaging with one of the engaging members of the body.

Abstract: An igniter includes a shell, a generator, a button and a security device. The generator includes a cylinder received in the shell and a plunger extending from the cylinder and being movable toward the cylinder in order to generate a voltage. The button is attached to the plunger. The security device includes a lever. The lever is pivotally received in the shell and formed with a hook for hooking the button. The security device and the button are located that a user contacts the security device before the button during an operation of ignition. A gas torch includes a shell, a tank, a valve, a generator, a button and a security device. The tank is received in the shell for containing fuel. The valve is mounted on the tank and movable between a closing position for keeping the fuel in the tank and an opening position for allowing the fuel to vent from the tank.

Abstract: A hair-curling appliance has a first end and a second end that is rotatably connected to the first end. When the operator moves the hair-curling appliance downward, the first end of the appliance held by an end of an operator is turned to curl the hair of another person, and the second end of the appliance held by the other hand of the operator is not turned during the downward travel of the appliance, thereby keeping a longitudinal axis of the appliance parallel to a horizontal axis and thus preventing deviation of the appliance. A satisfactory hair-curling result is thus obtained.

Abstract: A gas-heatable appliance for personal use receives an inflammable gas reservoir and comprises a combustion chamber and a valve assembly mounted between the inflammable gas reservoir and the combustion chamber. The valve assembly comprises a valve housing defining a gas passageway, a sealing member mounted in the gas passageway and movable between a first position allowing flow of the inflammable gas and a second position blocking the gas passageway, a movable member mounted in the gas passageway in a position other than the sealing member, and a temperature-responsive member disposed in the valve housing. The movable member is movable by the temperature-responsive member in response to a temperature of the combustion chamber to thereby vary an area of cross section permitting gas flow.

Abstract: A self-adjusting gas valve comprises a valve seat including an outlet passage. An adjusting rod comprises an end received in the valve seat such that the adjusting rod moves along a longitudinal axis thereof when it is turned. A control member comprises a first end engaged with the second end of the adjusting rod and a second end received in an inlet end of the outlet passage. The second end of the control member is moved along a longitudinal axis of the outlet passage to thereby control opening and closing of the inlet end of the outlet passage when the adjusting rod is turned. The first end of the control member is pivotable relative to the second end of the adjusting rod to completely block the inlet end of the outlet passage when the control member is moved to a closed position.

Abstract: A gas container comprises a container including a main chamber for containing flammable gas. The container comprises a valve seat in an end thereof, the valve seat defining a chamber communicated with the main chamber. A cover is mounted to close the end of the container. The cover includes an outlet communicated with the chamber of the valve seat. A valve stem is mounted in the valve seat and slidable between a closed position not allowing the flammable gas to exit the outlet through the chamber and an open position allowing the flammable gas to exit the outlet through the chamber. The valve stem is actuatable by an object extending into the valve seat via the outlet of the cover so as to be moved from the closed position to the open position.

Abstract: A hot melt glue gun including a housing, a heating chamber defined in the housing for heating a solid glue stick to its melting point, a sleeve for holding a portion of the solid glue stick outside the heating chamber, and an insulating member for prohibiting heat transfer from the heating chamber to the sleeve. The insulating member keeps the sleeve at a temperature below the melting point of the solid glue stick, thereby preventing melting of the portion of the solid glue stick outside the heating chamber.
