Abstract: An inline splicing system for brittle conductors which is comprised of a superconductor core, a superconductor coil having a length of conductor wound upon it with a terminal end, a supply spool of compatible conductor having a terminal end, both conductors being in an abutting relationship for a prescribed length, a spacer located between a portion of the abutting length and the core, and a soldering means which creates a solder along the abutting length that conforms to the circular surface of the core.

Abstract: A superconductive switch for a superconductive magnet is bifilarly wound on a bobbin with niobium-tin tape and laminated with stainless steel foil for structural rigidity is provided. The switch is vacuum pressure epoxy impregnated and cooled by copper bus bars which are heat stationed to a cryocooler which is also used to conduction cool the superconductive magnet. The bus bars are also used to introduce a voltage across the switch and the magnet windings which are connected in series with one another to ramp up the current.

Abstract: Four magnet cartridge axial supports are provided to prevent axial motion between the magnet cartridge and the surrounding vacuum vessel. Each axial support includes two high strength steel rods in parallel. The rods are brazed to a bar on one end which mounts to the magnet cartridge. The other end of the rods is brazed to a threaded stud which is secured by a bolt to a bracket secured to the vacuum vessel.

Abstract: The present invention is an apparatus for performing a joining operation to couple a first component to a second component. One embodiment of the present apparatus includes means for aligning the first component and the second component so that a first portion of the first component is aligned with a first portion of the second component, means for heating the first component so that a melt is formed at the first portion of the first component, and means for forcing the first portion of the second component into the melt so that when the melt solidifies, the first component and the second component are bonded. In the exemplification embodiment, the heating means is an Nd:YAG laser source which emits at least a first laser beam which impinges upon one of the components.

Abstract: This invention discloses an optical fiber connect/disconnect for power lasers. The connect/disconnect should allow a laser/fiber user to quickly interface fiber injection input and fiber output couples while providing electrical feedback and optical alignment. The connect/disconnect also offers an electrical feedback which should provide the user with operating parameters of the input and output couplers and/or the connect/disconnect assembly.

Abstract: A method for controlling process conditions in a continuous skull nozzle process is provided wherein one or more process parameters are controlled to maintain the operation of the process within a process window derived using integral solutions and expressed in terms of dimensionless parameters. The process window defines a range of values for the controllable process parameters within which a steady state solidified skull will be maintained and outside of which a steady state solidified skull will not be maintained. A pressure differential between the inside of a crucible holding the melt and outside of the crucible is one process parameter which is controlled to adjust the melt discharge flow rate to maintain operation within the process window.

Abstract: A method for soldering a lead to a pad having a solder plate formed thereon is described. In one embodiment of the method, a tape is disposed between the lead and a laser source, and the method includes the steps of aligning the lead with the solder plated pad, transmitting a beam from the laser source through the tape and to a location where a solder joint is to be formed, and the beam heating the solder plate thereby causing reflow of the solder plate to form a solder joint.

Abstract: A nozzle holder and sensor for a pressure pot peening system is disclosed. The holder includes a 90.degree. bend which is provided so that substantially the entire momentum of the mass of shot and air ejected from the nozzle can be sensed by the sensor and mass of shot and air ejected is not adversely affected if the hose from the shot peening system is moved. Also the holder can be oriented into a variety of positions and locations.

Abstract: A superconductive foil and a first and second foil of current conducting material. The first and second foil are soldered symmetrically about said superconductive foil forming a superconductive tape. The tape is wound in helical layers forming a coil. Adjacent turns of the tape are electrically insulated from one another. A strip of electrically conductive foil is situated between layers of tape and electrically isolated therefrom. The strip of electrically conductive foil encloses the inner layers of the tape, with the ends of the strip joined together to form an electrically conductive loop. The coil is epoxy resin impregnated.

Abstract: An apparatus and method for controlling the powder deposition and deposit pattern in a plasma spray process are provided in which an infrared imaging detector and associated processors are employed to provide an image of the temperature distribution of the deposit and to provide an identification of the impact point of the most recent powder deposit, and in which a cyclone separator or other device is used to modulate the flow rate of the carrier gas in which the powder is entrained at the point where the powder and gas are injected into a plasma plume, in order to move the impact point of the powder from the sensed location to a desired location. An injector tube is provided in a cross-flow injection system which may be sized to compensate for variations in the desired injection velocities of particles of different sizes, and the variations in the rate at which such particles are accelerated in the injection tube.

Abstract: A refrigerated superconductive magnet is provided with six magnet cartridge radial struts supporting the magnet cartridge in the vertical and lateral directions. The struts are positioned such that two lateral struts on each end of the magnet cartridge react against the contact force of the cryocooler cold head and support half of the vertical (gravitational) load of the magnet cartridge. Two vertical struts support the other half of the vertical load. The vertical struts pivot to allow the cartridge axial centerline to shrink towards the cryocooler interface during cool down. The strut attachment points have been located near the horizontal midplane in order to minimize the sag of the magnet cartridge due to its own weight.

Abstract: Two pair of thermal shield axial supports are provided. Each support includes a strand of wire brazed on either end into threaded studs. One stud is threaded into a topped hole in the end of the magnet cartridge. The stud on the other end extends through a clearance hole on the end flange of the thermal shield. Belleville spring washers are compressed against the shield by a nut. Prior to cool down, the Belleville washers are compressed. As the shield and magnet cool down, the shield contracts axially with respect to the magnet cartridge, thus relaxing the washer stack compression. The wire tension relaxes from the maximum pretension to a nominal tension at operating temperature.

Abstract: A cylindrical sleeve of thermally conductive material is provided together with two epoxy impregnated superconductive coils. The cylindrical sleeve defines a circumferentially extending rabbet on either end of the sleeve on the inner diameter. The edge of the outer diameter of each coil is secured in one of the rabbets in the sleeve.
