AbstractAbstract
[en] The initial stage of the quench process of a fully stabilized coil is modeled and analyzed. The model of exposed conductor is illustrated. Discussion of computed results includes graphs of the relevant data. The results have shown that the conductor temperatures and turn voltages remain relatively low while the conductor is in a quasi-steady state condition where it conducts heat to a slowly dropping liquid helium level. Once the limits of this quasi-steady condition are exceeded the conductor temperature and voltage have a rapid rate of rise with time

AbstractAbstract
[en] One half of the receiver coil turns are wound onto the sample holder such that the turns are spaced to the wire width and the remaining turns are wound in the gaps of the already wound half of the receiver coil. The direction of winding is from the rear to the front face of the receiver coil and the wire ends are twisted. In a magnetic resonance spectrometer with a detection signal coil system the scattering signal transmitted from the transmitter coil immediately to the receiver coil is significantly lower. (J.P.)

AbstractAbstract
[en] A single-zero divertor is described. It contains a conductor, placed in a tokamak discharge chamber, and receprtor plates. The conductor is made in the form of a single-coil spiral in order to decrease the power consuption, to simplify the design and to improve the plasma filament stability. So, the conductor makes one revolution over the small pass-around of the torus per one revolution over the large pass-around of the torus. The receptor plates are located in the regions where the spiral conductor intersects the external and internal generatrices of the torus. The conductor is connected to the power sources so that current in the conducter runs in the direction opposite to current in a plasma

AbstractAbstract
[en] A small RF probe for the inspection of, for example, the uterine cervix by magnetic resonance imaging is described. It comprises a cylindrical coil and two saddle coils conforming to the shape of this coil on a former. The saddle coils are sensitive to volumes above and below the cylindrical coil to which this coil is not sensitive given a main magnetic field in a direction perpendicular to its axis. (author)

AbstractAbstract
[en] Recent advances in direct lightning strike testing have been in lightning attachment test techniques and generator development using a very large Tesla Coil (51 feet wide). Breakthroughs in simulated lightning attachment to small scale replica aircraft models which can be adapted to full size operational aircraft have been made in the past year. New high voltage long arc generator developments have succeeded in producing voltages in excess of 15 million volts and arc lengths in excess of 40 feet. The shortest path from the discharge arc electrode to the model extremity using the long arc does not govern the attachment points to the test specimen as it does when a short arc is used to conduct simulated lightning testing. The system just described may also have application as an ultra-high mega-volt source for particle beam weaponry

AbstractAbstract
[en] A superconducting magnetic sensor having a sensing coil is provided with one or more superconducting discs for adjusting the effective area of the coil. The effective area of the coil is adjusted by varying the position of the superconducting disc relative to the associated coil. In a superconducting gradiometer having a pair of sensing coils coupled in series opposition, three superconducting discs are arranged to provide effective area adjustment along three mutually orthogonal axes. Coarse and fine adjustment are optionally provided by employing two sets of superconducting discs, one set fixed, the other adjustable

AbstractAbstract
[en] A proton-synchrotron comprises 270 electro-magnets disposed on a circle 400 meters in diameter. It is required to finely position (0.05mm) each of these electro-magnets weighing about 20 tons both horizontally and vertically. Moreover, each of the electric magnets must be capable of easy replacement. Conventional systems are uneconomical since vertical positioning is made by a screw jack, and horizontal positioning by two-stage rails. The present invention employs three screws and slide guides for horizontal positioning. Each of the positioning apparatuses consists of a guide, a ball slide, a cylinder, a sliding screw and a handle. Manipulation of the handle rotates the screw and moves the cylinder and the ball slide slowly in the horizontal plane and carries the electric magnet supported on a ball slide by the guide in the horizontal direction. Vertical adjustment is made by a screw jack. (R. Masui)
