This produces good noise damping in an inward direction.

Abstract: The windings of an NMR magnet coil are formed of at least two adjacent non-crossing conductor paths which are electrically insulated from one another. Each conductor path of a partial coil can be transformed geometrically into one respective conductor path in each partial coil through the symmetrical operations. The various conductor paths in each partial coil are coded in such a manner that the conductor paths adjacent to one another in a winding and attributed with identical successive cardinal numbers as code numbers in their geometric order. The conductor paths in the various partial coils which can be transformed into one another through symmetrical operations have the same code numbers. Each conductor path in a partial coil is electrically connected in series with one conductor path each in at least one other partial coil. These series connections of conductor paths are electrically connected to one another in parallel.

Abstract: Magnetic shielding for a superconducting magnet coil, arranged in the inside of a cryostat and having a vertical z-axis for generating a static magnetic field of a homogeneity of <10−7 in the measuring volume of an NMR spectrometer, wherein the shielding comprises spatial shielding at a distance from the cryostat in the form of a ferromagnetic shielding plate arranged above the cryostat, is characterized in that the shielding plate comprises either areas outside of the z-axis having a final curvature in the downward direction or plane surfaces which are inclined with respect to the horizontal line at an angle 10°<theta<60°, truncated conical or truncated pyramid shaped surfaces. In this manner, the magnetic flux in a room located above the spectrometer is minimized and the expenditure for material and assembly for the shielding elements is considerably reduced.

Abstract: The circuit arrangement for generating two signals staggered in time from a clock signal and for measuring their time stagger receives at its input a clock signal, from which it generates an undelayed signal and a signal delayed relative to the undelayed signal. The generated signals appear at a first and second output of the circuit arrangement, respectively. A delay time measuring arrangement comprises a reversible inverter connected between the input of the circuit arrangement and the first output of the circuit arrangement and a NAND gate. The NAND gate receives at one input the delayed signal and at the other input the output signal of the inverter and furnishes an output signal from which the time stagger existing between the undelayed signal and the delayed signal can be precisely determined. The reversible inverter is switchable by a switching signal between a non-inverting condition in a working phase and an inverting condition in a measuring phase.

Abstract: Measuring the level of a material in a container using a sensor fitted above the highest level occurring and measuring the distance to the surface of the material in the container. An evaluation circuit computes the level from the distance measured by the sensor and the empty distance. The material volume is determined from the relationship between level and material volume memorized in the evaluation circuit. For calibrating a sensor in the case of an unknown empty distance, without having to completely empty the container, the on-going filling or emptying of the container is interrupted and the actual material volume is recorded. Using the sensor to be calibrated a distance measurement is implemented and the actual material volume is entered in the evaluation circuit.

Abstract: In an NMR apparatus with a system of gradient coils for the production of a magnetic field gradient within a measurement volume (1) within a field coil, the transverse gradient coils are constructed unsymmetrically with respect to the z=0 plane dividing the measurement volume (1), however largely mirror symmetric to a x=0 or y=0 plane containing the z axis, and possess only two partial coils (20', 20''; 40', 40'') whose windings each exhibit the same winding direction. The axial gradient coils are cylindrically symmetric with respect to the z axis and totally unsymmetric with respect to the z=0 plane, and consist of at least two partial coils which are arranged on differing sides of z=0 plane, whereby the partial coils on one side largely exhibit the opposite winding direction than the coils on the other side, and whereby the number of coils with a particular winding direction is not equal to the number of coils with the opposite winding direction.

Abstract: In a method for the production of a magnet coil arrangement which can create a predetermined magnet field B and has a minimal inductance L. The magnetic field B to be generated is expanded in spherical harmonics with coefficients C.sub.n,m and a field error .DELTA. B=f.sub.1 (C.sub.n,m) is defined fixing the deviation of the magnet field profile of the coil arrangement to be calculated from the given magnet field B within a volume and, if necessary, further parameters P=f.sub.2 (C.sub.n,m) are predefined, whereby the value of P which is calculated with a particular set of coefficients C.sub.n,m is within predetermined limits. By defining limits for technically relevant parameters and their variation as well as by giving the desired minimum inductance, the procedure achieves a high flexibility in conjunction with independent optimization of the parameters, in particular field errors, minimum inductance and current density oscillations.
