    摘要: A compact heater is designed for the deposition of thin films at high temperatures in an oxidizing atmosphere or in vacuum. The heater is designed to accommodate a small-diameter load-lock system in an ultra-high-vacuum deposition chamber, and can operate in 0 to 1 atmosphere of oxygen up to at least 800.degree. C. The compact design allows the heater, including a substantially isothermal substrate holder having the substrate affixed thereto, included temperature sensor and attached main body portion, to be loaded through a load-lock port with about a 2.5 inch inside diameter. Heat is generated resistively, and the substrates are heated directly by thermal conduction. The heater was designed specifically to heat substrates to precisely monitored temperatures during the growth of high-temperature superconducting thin films.

    摘要: A superconducting magnet module comprises an alternate series of abutting and coaxially aligned first and second superconductive magnet modules. The first magnet module includes a first substrate having opposed first and second faces and a bore filled with a superconductive material extending between the first and second faces. The first face is formed of an electrically conductive material and the second face is formed of an electrically insulating material. A first spiral track of the superconductive material is formed on the first face in electrical and thermal contact with the electrically conductive material. The first spiral track is melt fused to the superconductive material in the bore. The second magnet module includes a second substrate having opposed third and fourth faces. The third face is formed of an electrically conductive material and the fourth face is formed of the electrically insulating material. A second spiral track of the superconductive material is formed on the third face in electrical and thermal contact with the electrically conductive material. The modules are positioned so that the second track abuts the second face and is melt fused to the superconductor in the bore to provide the superconducting magnet with a solenoidal and monolithic superconductive current path.The melt-fused spiral tracks provide the superconducting magnet with a quasi-helical and monolithic superconductive current path which may be tailored to have a uniform critical current capacity.

    摘要: The present invention provides a method for determining the granular nature of superconductive materials and devices which includes the steps of: conducting a substantially rectangular current pulse through the superconductive material, maintaining the temperature of the superconductive material at a substantially constant temperature which does not exceed the critical temperature of the superconductive material; determining the amplitude of the current pulse; determining the electrical resistance, R, of the superconductive material resulting from conducting current pulse through the superconductive material; increasing the current until the electrical resistance of the superconductive material becomes saturated; determining the electrical resistance difference, .delta., between the electrical resistance, R, of the saturated superconductive material and a total normal state electrical resistance of the superconductive material; generating a first output signal if .vertline..delta..vertline..ltoreq..epsilon., where .epsilon. represents a predetermined limit, where the first output signal corresponds to the superconductive material having a homogenous microscopic morphology; and generating a second output signal if .vertline..delta..vertline.>.epsilon., where the second output signal corresponds to the superconductive material having a granular morphology.

    摘要: The present invention provides a method for measuring the intragranular andntergranular critical current of a granular superconductive material, comprising the steps of: 1) conducting a substantially rectangular electronic pulse through the material so as to conduct a current through the material such that when the intergranular critical current of the material is exceeded, any grains present in the material remain in a superconducting state when the current level is below the intragranular critical current; 2) measuring the current through the material while conducting the pulse; 3) measuring a voltage difference across the material while conducting the pulse; 4) determining the intergranular critical current through the material by discerning a non-zero voltage difference across the material and contemporaneously measuring the current; and 5) determining the intragranular critical current through the material by varying the current to discern a current level at which the electrical resistance of the material increases to that of the non-superconducting state as the grains of the material transition from the superconducting to a non-superconducting state. This method may also be used to determine the critical current of a homogeneous superconductive material.

    摘要: The disclosure concerns a vehicle which is both lifted and propelled by air flow. The vehicle comprises an upper deck, a depending peripheral side wall and a flexible, perforated sheet secured beneath the bottom of the side wall, thereby defining an open plenum. A propeller in an air flow directing cowl seats atop the deck and part of the air flow is directed into the plenum and the remainder of the air flow is directed to move the vehicle. The underside of the upper deck disperses air in the plenum. Alternatively, the propeller is part of a duct which directs air into and disperses it around the plenum. The cowl includes an air dam for trapping reverse flowing air. A rudder directs the motion of the vehicle. The plenum narrows in width toward the front and diminishes in height away from the plenum inlet through the upper deck. In an alternate embodiment, the cowl has louvered exits along both lateral sides, and selective opening and closing of these louvered exits turns the vehicle, brakes it or even causes it to move in reverse. The main exit from the cowl is then provided with a shutter which is movable to control the speed of the vehicle and which when closed cooperates with the louvers for moving the vehicle rearwardly. In another alternate embodiment, the vehicle has a plurality of separate ones of the plenums beneath its deck. Finally, a train of the vehicles may be made, with a single airflow supplying air to all the plenums.

    摘要: A plug for a sewer pipe has an inner sleeve with threaded opposite ends. A pair of longitudinally aligned outer sleeves having cylindrical outer surfaces and opposite end edges are slidably mounted on the inner sleeve. An inflatable tube is carried by the outer sleeves, the tube having inner and outer walls as well as end folds. Air valves are fitted to the end folds to admit pressurized air into an air chamber provided within the tube. The threaded opposite ends of the inner sleeve are each fitted with a collar which is engaged by an end closure provided with an inlet port and an outlet port. Removable stoppers normally close each inlet and outlet port. The plug can be inflated within an end of a sewer line to provide a positive leakproof seal against a head of water. Also two of the plugs can be connected together in an assembly which allows a sewer line to be pressure tested.
