摘要： A weighing system of the electromagnetic load compensation type is disclosed including a counter for counting the weight-responsive pulses which are produced during the periods that the compensating current is supplied to the movable coil to return the movable scale member toward its initial no-load position, characterized by the provision of a temperature-responsive device for supplying to the counter a train of temperature-correction pulses that are used to modify the count of the weight-responsive pulses, whereby a more accurate indication of the applied load is obtained. Thus, an analog signal from the temperature sensor is compared with a sawtooth signal to produce a digitalized temperature-responsive signal which modifies the digital weight signal supplied to the microprocessor circuit.

摘要： An NMR (nuclear magnetic resonance) apparatus has a magnet system disposed in a cryostat (1), the cryostat having at least one nitrogen tank (3b) for receiving liquid nitrogen (5b) and a room temperature bore (7) for receiving an NMR probehead (8), wherein part(s) of the probehead or the overall probehead can be cooled to cryogenic temperatures by supplying liquid nitrogen (5b) via a supply line (14). The nitrogen tank (3b) of the cryostat (1) is connected to the NMR probehead (8) by means of a supply line (14) in such a fashion that liquid nitrogen (5b) is removed from the nitrogen tank (3b) and guided to the NMR probehead (8). The overall apparatus is therefore more compact, the operating comfort of the apparatus is increased, and the costs for acquisition, operation and maintenance are considerably reduced compared to previous comparable devices.

摘要： An RF receiver coil configuration for NMR spectrometers has at least two largely mutually orthogonal RF receiver coil systems of which at least one is made from superconducting material and is at least partially cooled to a cryogenic temperature lying far below room temperature, with each RF receiver coil system comprising at least one single coil arranged symmetrically about a sample the RF receiver coil systems having differing radial separations from the sample. The inner RF receiver coil system is made from a material having differing physical characteristics in dependence on the actual operating temperature than the material of the outer RF receiver coil system, with the materials and the geometries of the RF receiver coil systems being chosen to minimize the influence of the susceptibility of the RF receiver coil system on the homogeneity of the magnetic field in the vicinity of the sample. In this fashion, the high Q values of the resonator configuration achieved by the use of superconducting material with high electrical RF conductivity can be taken advantage of while, at the same time, avoiding the substantial interfering influences of the high susceptibility of the superconducting material.

摘要： In a method for compensation of time variant field disturbances in magnetic fields of electromagnets with high field-homogeneity, in particular in sample volumes of superconducting electromagnets for measurements of magnetic resonance, the dispersion signal u.sub.x of the nuclear signal of a reference substance is acquired and taken into consideration for compensation by generation of a current dependent on the dispersion signal in a field correction coil of the electromagnet. The method is characterized in that the absorption signal u.sub.y of the reference substance is additionally acquired and that the compensation is carried out in dependence on the quantity u.sub.x /u.sub.y and/or (1/u.sub.y)(du.sub.x /dt). These are substantially independent of many influencing quantities.
