Abstract: A hockey stick blade application/removal tool for applying a replacement blade to or removing a replacement blade from the blade receiving end of a hockey stick handle. The tool includes a wrap-around heat panel, an insulative layer surrounding the heat panel and a connection member for connecting the heat panel in such wrap around configuration.

Abstract: A control circuit is disclosed which uses AC power input and provides DC power output which is not limited by DC semiconductor switch power dissipation capabilities. Switching is performed on the AC signal to provide time proportional AC power which is then transformed and rectified to provide relatively high proportional or adjustable power to a DC load without electrical noise. The DC load is monitored for a controlled characteristic, such as temperature, and a monitor signal is provided to a control for controlling the time proportional AC power output, in accordance with the DC load demand. A dimensionally stable temperature controlled semiconductor test chuck is described presenting a DC heater load for the control circuit.

Abstract: A method and apparatus for electron or laser beam welding of semiconductor subassemblies to larger terminal members, without exposing semiconductor chips in such subassemblies to detrimental welding "flash".

Abstract: A vacuum furnace has a heating chamber heated by metal strip electric heater elements. The elements have insulated mechanical support between their ends to hold them in position in the furnace. Support is provided by a ceramic post having an internal thread in an outer end threaded onto a rod secured to a portion of the furnace. A transverse member at an inner end of the post includes a straight surface normal to the length of the post for engaging the heater element. The heater element is compliantly connected to the straight surface. One embodiment of heater element support is in the form of a T-shaped ceramic post having an internal thread in the leg of the T and a ceramic crossbar having a straight surface normal to the length of the post for receiving the heater element. Another embodiment has a ceramic post having an internal thread in the outer end of the post and a metallic crossbar having a straight surface normal to the length of the post for receiving a heater element.

Abstract: A combination evaporator and radiant heater defrost means including a heater housing which prevents defrost water from impinging directly on the heater while enhancing defrosting of the evaporator.

Abstract: An electric resistance element (1) in a device for deicing a wing structure such as the wing of an aircraft or the blades of a helicopter, which includes conducting fibers embedded in a composite fiber structure and power supply wires connected electrically to said conducting fibers. In this element, the conducting fibers are carbon fibers in the form of at least one ribbon (2) in which the fibers are oriented longitudinally, preimpregnated with resin and at least one end of which is fixed in a deformable tubular metal mesh element (3) providing the electric connection by contact with the ribbon and which in turn is soldered to the corresponding power supply wire (4).

Abstract: For use in placing a semiconductor substrate in molecular beam epitaxy apparatus, a holder comprises a heat conductor member opposite to a substrate. The substrate is received in a space formed in a supporting member and is in engagement with a flange portion radially inwardly projected from a peripheral surface of the space. The heat conductor member is heated by a heater in the molecular beam epitaxy apparatus. This results in effective conduction of heat to the substrate. The substrate is easily put in the beam epitaxy apparatus and removed therefrom. The heat conductor member may be of pyrolytic graphite or sintered graphite.

Abstract: An electrically heated handle, particularly for fishing rods, has an elongated thermally conductive shell enclosing an interior chamber in which is located a solid body of a material having high electrical resistance, such as Steatite, defining a heater core having its entire outer surface in heat transfer engagement with the shell. An elongated electric heating coil, e.g., of Nichrome, extends longitudinally through the interior of the heater core and is connected to an external power source through a switch and power supply conductors extending through the rear end portion of the handle. The front end portion of the handle is formed with an elongated socket chamber thermally insulated from the interior chamber and adapted to receive and fit over the butt end of a fishing rod. Once the heater core of the handle is initially heated, the heat is stored for slow dissipation to the handle and hand of the holder, requiring infrequent replenishing of electric current to the electric heating coil.

Abstract: A portable heater for radiantly heating the underbody, particularly the engine oil pan or crankcase, of a motor vehicle to facilitate starting in cold weather includes an elongate wheeled support member horizontally positionable adjacent and under the vehicle by a handle on one end of the support member. A radiant energy generator, such as a conventional infrared lamp or an electric resistance element, is mounted on the support member and oriented to project a beam of radiant energy substantially parallel to and along the longitudinal axis of the support member to a planar reflector on the support member downstream of the generator and disposed at an angle to reflect the beam of radiant energy upwardly to portion of the vehicle underbody desired to be heated.

Abstract: A heating plate, especially for presses utilized to bond two belt ends together, e.g. in the formation of an endless conveyor belt or in the repair of a conveyor belt. According to the invention, the heating effect over the plate which is rectangular or of rhombic configuration, is held uniform by distinguishing between longitudinal edge zones, transverse edge zones, central zones and corner zones, all of which have essentially the same specific volume of material, i.e. the same volume of material with a unit area of the heating surface. A frame work of longitudinal and transverse edge members of the same cross section and intermediate members parallel to the longitudinal edge member and equidistant from one another is sandwiched between a heating plate and a cover plate and the heating elements lie adjacent the heating plate in the spaces between the longitudinal and intermediate members.

Abstract: An electric space heater having a pair of feet which are initially detached from the heater body to permit shipping in a small carton. The heater body has downwardly projecting fingers which are resilient in order to snap into receptacles of the feet when the feet are applied to the heater body for permanent attachment thereto. Curved ribs project downwardly between the opposing sets of fingers and act to upset the heater if an attempt is made to operate it without the feet attached. A tilt switch deactivates the heater when it is upset. When the feet are attached to the heater body, the ribs fit in sockets of the feet to permit normal heater operation.

Abstract: An electric hot plate has a molybdenum disilicide resistance wire heating element spaced above a fibrous refractory pad by wire supports and spaced below a transparent glass plate forming a cooking surface. The pad has a smooth top surface, the wire is looped back and forth sinuously or possibly spirally coiled to form a layer which is parallel with the pad surface and the glass plate, and the wire is designed to operate at temperatures preferably of from about 2300.degree. to 2500.degree. F. or higher, at which temperatures the pad surface has been found to be effective for diffusely reflecting upwardly the wire heat radiation.
