Abstract: A storage electric sealer comprises a casing, a sealing module, a spring switch, a support cover, a press bar, and a sliding plate. The casing and the sealing module are arranged on the casing. The support cover includes at least two containing grooves. The press bar provided with a sliding chute is pivotally connected with the pivoting holder of the casing. The sliding plate is provided with a heat insulation block and at least a stopper, both lateral side of the sliding plate being connected with the sliding chute of the press bar in a sliding manner. Wherein, the sliding plate is located at a closed position in storage state, so that the stopper is accommodated in the containing groove of the support cover. As such, the storage electric sealer can be transformed into a storage state by a modified sliding mechanism to reduce the volume and damage rate effectively.

Abstract: A gas bolt heater for loosening large bolts and studs has a hollow cylindrical housing defining a cylindrical chamber within the housing. A heating tube projecting from one end of the housing has a longitudinal bore. A first cylindrical insert closing the lower end of the chamber has a through opening communicating with the bore of the heating tube, and a second cylindrical insert located within an opposite end of the cylindrical housing has an elongate passage extending axially of the cylindrical housing. Downwardly convergent air passages in the second cylindrical insert have mouths distributed around the elongate passage, at a lower end of the passage, and an air supply duct communicates through the cylindrical housing with the air outlet passages.

Abstract: A heating apparatus using liquefied gas comprises a control valve which controls the gas flow rate by the rotating operation of a flow rate control member and which is rendered open to discharge a gas under flow rate control from the top end of a cylindrical valve body when the body is caused to slide, and a control valve operating mechanism mounted to the control valve which causes the valve body to slide when the mechanism is displaced toward axially, as well as causes the flow rate control member to rotate when the mechanism is rotated circumferentially.

Abstract: A portable, flame powered sealer including a sleeve-like body portion receptive to a standard, throw-away type cigarette lighter, a pair of upwardly extending brackets, a heating element held over the flame of the lighter by the brackets, and a compression member pivotally attached to one of the brackets for pressing a portion of the bag proximate its mouth against the heating element.

Abstract: An applicator for hot melt adhesives. The applicator comprises a heat exchange barrel having a nozzle at one end and an opening at the other end for receiving a stick of hot melt adhesive, the barrel being attached to a cigarette lighter in heat transfer relation with its flame, so that when the adhesive stick is forced through the barrel in the presence of the flame, molten adhesive flows from the nozzle.
