Abstract: A portable curling iron having a barrel to be heated, includes first and second burners which heat the barrel; a fuel supply cartridge which supplies fuel to the first and second burners, the cartridge including a fuel delivery valve which controls the flow of fuel from the cartridge; a plunger which applies a force to the valve in response to user actuation, to start the flow of fuel from the cartridge; a regulator assembly including a diaphragm which applies a reverse force to the plunger when the gas pressure exceeds a predetermined pressure, to maintain a substantially constant flow rate of fuel to the first and second burners; a valve stem through which the fuel travels from the cartridge to the second burner; a bimetallic element for applying a force to the valve stem to permit the fuel to pass to the second burner when the temperature is less than a predetermined start-up temperature and for removing such force when the predetermined start-up temperature is attained; and a spring which applies a revers

Abstract: A portable solder iron includes a hollow barrel having a free tapered end; first and second burners positioned in a free tapered end; a burner having separate, independently controlled gas supply paths positioned in the barrel, the supply paths including first and second tubes, each tube having a free end; a single junction tube joining together the free ends of the first and second tubes, the junction tube having a free end adajcent the tapered free end of the barrel for heating the same; a fuel supply cartridge which supplies fuel to the first and second tubes and which controls the flow of fuel from the cartridge; an ignitor assembly for igniting the fuel escaping from the free end of said junction tube; a plunger which applies a force to the valve in response to user actuation, to start fuel flow; a regulator including a diaphragm which maintains a substantially constant flow rate of fuel to the first and second tubes; a valve stem through which the fuel travels from the cartridge to the second tubes; a b

Abstract: A portable heating appliance having a member to be heated, includes burner tubes for heating the member; a fuel supply cartridge for supplying fuel to the burner tubes, the cartridge including a stationary fuel delivery valve for controlling the flow of fuel from the cartridge; and an actuator assembly for actuating the fuel delivery valve in response to user actuation to start the flow of fuel from the cartridge, the actuator assembly including a plunger, a mechanism for moving the plunger to a first position into operative engagement with the fuel delivery valve for opening the fuel delivery valve and a mechanism for moving the plunger to a second position out of operative engagement with the fuel delivery valve so that the latter terminates the flow of fuel to the burner tubes.
