    摘要： A sensor arrangement for detecting a variable that is to be measured, has at least two substantially similar sensor elements. These sensor elements each produce an output signal in response to the variable to be measured, the output signals having a Hall voltage disturbance component. The two sensor elements are orientated in relation to each other in such a way that a sensor signal can be produced by a combination of their output signals, the Hall voltage disturbance components being compensated in the sensor signal.

    摘要： A force/torque sensor has a semiconductor region which is adapted to be subjected to a force or torque. Two control electrodes are provided on a first and a second side of the semiconductor region, the sides being arranged in spaced, opposed relationship with one another, and a current through the semiconductor region being producible between the control electrodes. Two sensor electrodes are provided on a third and a fourth side of the semiconductor region, the sides being also arranged in spaced, opposed relationship with one another and extending essentially at right angles to said first and second sides. A force or torque applied to the semiconductor region is determinable by detecting a voltage present between the sensor electrodes when a current flows between the control electrodes. The semiconductor region is formed by the channel of a field effect transistor, the drain an source electrodes of said field effect transistor defining the control electrodes.

    摘要： A hydrogenation catalyst comprising 25 to 50% by weight of nickel (metallic) 10 to 35% by weight of nickel oxide 4 to 12% by weight of magnesium oxide 1 to 5% by weight of sodium oxide the remainder being a water-insoluble support material,wherein the total of nickel and nickel oxide is 40% to 70% by weight, and the catalyst has a surface area, determined by BET, of 80 to 200 m.sup.2 /g and a total pore volume of 0.35 to 0.6 ml/g. The total pore volume is made up of 30% to 60% by volume from pores having pore radii of .ltoreq.40 .ANG., 4% to 10% by volume from pores having pore radii of >40 to 300 .ANG., and 30% to 60% by volume from pores having pore radii of >300 to 5000 .ANG..A process for preparing the hydrogenation catalyst which comprises preparing, in a precipitation step, a green catalyst from a nickel salt, a magnesium salt, sodium carbonate, and the support material, separating off the mother liquor and partially washing the precipitate, slurrying the green catalyst in alkali solution, separating it from the liquid phase, drying it, and contacting the dried green catalyst with hydrogen until 48% to 86% by weight of the total nickel content is present in metallic form.The hydrogenation catalyst of the invention is particularly suitable for the hydrogenation of propanal, n-butanal, and i-butanal, especially at temperatures between 100.degree. and 160.degree. C.
