Patent number: 5919387Abstract: A method for bonding or joining plastic or metallic pipe using induced energy is provided. A susceptor is placed between the two pipes to be joined and a magnetic flux is induced onto the susceptor. The second pipe may be a coupling device. The magnetic flux may be induced by a tank circuit or an induction heating gun. The induction heating gun may be formed with a hinged heating head. The susceptor may be a perforated metal ring or a wire coil. The susceptor is coated with a material compatible with the pipes, for example, a plastic adhesive material, magnetic flux is an induction heating gun having a hinged heating head.Type: GrantFiled: April 3, 1997Date of Patent: July 6, 1999Assignee: The United States of America as represented by the United States National Aeronautics and Space AdministrationInventors: John D. Buckley, Robert L. Fox, Samuel D. Johnson, Carl E. Copeland, Robert H. Coultrip

Patent number: 5350902Abstract: An induction heating device includes a handle having a hollow interior and two opposite ends, a wrist connected to one end of the handle, a U-shaped pole piece having two spaced apart ends, a tank circuit including an induction coil wrapped around the pole piece and a capacitor connected to the induction coil, a head connected to the wrist and including a housing for receiving the U-shaped pole piece, the two spaced apart ends of the pole piece extending outwardly beyond the housing, and a power source connected to the tank circuit. When the tank circuit is energized and a susceptor is placed in juxtaposition to the ends of the U-shaped pole piece, the susceptor is heated by induction heating due to a magnetic flux passing between the two ends of the pole piece.Type: GrantFiled: May 12, 1993Date of Patent: September 27, 1994Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert L. Fox, Copeland, Carl E., Robert J. Swaim, Robert H. Coultrip, David F. Johnston, W. Morris Phillips, Samuel D. Johnson, James R. Dinkins, John D. Buckley

Patent number: 4767484Abstract: A method is provided to bond strain gauges 6 to various materials. First, a tape 9 with an adhesive backing 10 is placed across the inside of fixture frame 8. Strain gauge 6 is flatly placed against adhesive backing 10 and coated with a thin, uniform layer of adhesive 5. Tape 9 is then removed from fixture frame 8 and placed, strain gauge side down, on the material to be tested. If the material is a high reluctance material 12, induction heating source 20 is placed upon tape 9. If the material is a low reluctance material 13, a plate 23 with a ferric side 21 and a rubber side 22 is placed, ferric side down, onto tape 9. Induction heating source 20 is then placed upon rubber side 22. If the material is an insulator material 14, a ferric plate 7 is placed on tape 9. Induction heating source 20 is then placed on ferric plate 7.Type: GrantFiled: July 17, 1987Date of Patent: August 30, 1988Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdminstrationInventors: Timothy D. Schott, Robert L. Fox, John D. Buckley

Patent number: 4521659Abstract: This device for inductively heating and fusing thermoplastics includes an alternating current passing through a tank circuit, the inductor member of the tank circuit being wrapped around a curved pole piece of a ferromagnetic material. The magnetic flux arising within the inductor coil member flows to the ends of the pole piece and into a screen placed between the materials to be joined. The flux induces a current in the screen, and heat is generated to melt the thermoplastics together. Because only 30-150 watts of power are passed through the tank circuit, a wire which will remain cool under operational wattage may be selected, making air or fluid cooling unnecessary.Type: GrantFiled: June 24, 1983Date of Patent: June 4, 1985Assignee: The United States of America as represented by the Administrator of the National Aeronautics & Space AdministrationInventors: John D. Buckley, Robert J. Swaim, Robert L. Fox, David F. Johnston

Patent number: 4488335Abstract: The invention relates to a hot melt adhesive attachment pad for releasably securing distinct elements together and particularly useful in the construction industry or a spatial vacuum environment. The attachment pad consists primarily of a cloth 11 selectively impregnated with a charge of hot melt adhesive 12, a thermo-foil heater 13 and a thermo-cooler 14. These components are securely mounting in a mounting assembly 17 and 18. In operation, the operator activates the heating cycle transforming the hot melt adhesive to a substantially liquid state, positions the pad against the attachment surface, and activates the cooling cycle solidifying the adhesive and forming a strong, releasable bond.Type: GrantFiled: July 22, 1983Date of Patent: December 18, 1984Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert L. Fox, Alan W. Frizzill, Bruce D. Little, Donald J. Progar, Robert H. Coultrip, Richard H. Couch, John R. Gleason, Bland A. Stein, John D. Buckley, Terry L. St. Clair

Patent number: 4313777Abstract: This fastener used in induction heating is a wire screen basically of an eddy-current carrying material such as carbon steel. Selected wires in the screen are copper, sheathed in an insulating material. The screen is placed between two sheets of thermoplastics. When inductively heated, the composite softens and flows around the apertures of the screen. After this heating and joining, the copper wires may be used to conduct electricity.Type: GrantFiled: August 30, 1979Date of Patent: February 2, 1982Assignee: The United States of America as Represented by the United States National Aeronautics and Space AdministrationInventors: John D. Buckley, Robert J. Swaim, Robert L. Fox
