    摘要: A cooling apparatus for a low temperature magnet system includes a superconducting magnet coil (32) which encircles a test space (36). The magnet coil (32) is surrounded by at least one intermediate shield (26, 29) and is contained in an evacuated outer shell (22). On the outer shell (22) is a motor driven refrigerator (11) which actively cools the at least one intermediate shield (26, 29) by means of a cooling arm (18) extending through the outer shell (22). For compensating the disturbing fields emitted by the motorized drive of the refrigerator (11) a sensing device is provided for picking up these magnetic and/or mechanical disturbing signals. The sensor signal controls at least one coil (62) for compensating the disturbing field effective in the test space (36).

    摘要: A method for producing tungsten compounds low in phophorus. Calcium tungstate is precipitated from a tungstate solution possibly containing phosphate with a calcium compound. The resulting precipitate is reacted with an alkali carbonate solution under pressure of preferably 15 to 25 bar and the solution resulting is separated from the residue containing substantially all of the phosphate. The resulting solution is collected and is suitable for production of tungsten compositions low in phosphorus.

    摘要: An operator safety device includes a plurality of covers for covering parts of a machine to protect an operator against contact with these parts when the machine is in operation. At least some of the covers are movable between a closed position where the covers do not cover these parts and the latter are readily accessible and constitute a danger of accidents. A switch is operable for shutting down the machine when at least one of the covers moves from the closed into the open position. A linkage connects the covers with the switch for actuating the latter whenever at least one of the covers moves from the closed into the open position.

    摘要: A gradient system for a nuclear spin resonance (NMR) tomograph with a main magnet system producing a homogeneous magnetic field directed along a z-axis inside a measuring volume, wherein the main magnet system provides access to the measuring volume along the z-axis and transversely to the z-axis, and wherein the gradient system comprises two first partial gradient systems which are located at opposite sides of a central plane perpendicular to the z-axis, across the measuring volume. At least one of the two partial gradient systems is movable between at least two positions along the z-axis. In this way, with a small constructional size and with a simple manufacturing procedure, a gradient system is obtained with high performance capability with respect to generated gradient strength for given ampere turns, high linearity of the generated gradient fields, minimum inductance and minimum electrical resistance of the conductor segments.
