    摘要： A MANDREL HAVING EXTERNAL THREADS AND AN INNER END PORTION WITH AN OPENING EXTENDING THERETHROUGH AND CONFORMING TO THE CONFIGURATION OF A VALVE SEAT IS POSITIONED IN A MOLD CAVITY. A SMALL TUBE IS POSITIONED IN SPACE RELAT2ON TO THE MANDREL IN ALIGNMENT WITH THE OPENING IN THE MANDREL AND A WIRE IS EXTENDED THROUGH THE CAVITY, TUBE, AND OPENING IN THE MANDRE. THE MOLD CAVITY IS FILLED WITH

    PLASTIC MANDREL TO FORM A VALVE BODY ABOUT THE MANDREL, TUBE, AND WIRE. AFTER THE PLASTIC MATERIAL HAS CURED, THE WIRE AND MANDREL ARE REMOVED AND AN ADJUSTABLE VALVE MEMBER IS INSERTED INTO THE CHAMBER FORMED BY THE MANDREL. A PLURALITY OF SUCH CHAMBERS MAY BE FORMED IN THE VALVE BODY.

    摘要： A heater includes a housing enclosing a heat exchanger, an aerosol can adapter for attaching the heater to an aerosol shaving cream can, a stem for actuating the aerosol can valve, and resilient foam insulation between the can and the heat exchanger. The heat exchanger has a cavity in one side receiving an electric heating element and a spiral heating passage in the other side to provide long residence times for heating fluids forced through the passage. A thermo-setting epoxy material provides electrical and heat insulation for the heater. Additional foam may be used for filling an electrical connection cavity above the heat exchanger, or the heat exchanger electrical connections may be encapsulated along with the heat exchanger by injection molding.
