    摘要: A method for analyzing water or other liquid, in particular rain water, comprises the steps of providing a collector comprising at least first and second volumetric cells and a mechanism for causing water to flow selectively into the cells and for causing water to flow selectively from the cells. Water is caused to flow into a first one of the cells while it is prevented from flowing into the other one of the cells. The water collected in the first cell is caused to flow to a property determining cell when the first cell has been filled to a predetermined volume, and simultaneously water is prevented from flowing into the first cell while it is now permitted to flow into the second volumetric cell. The water collected in the second cell is then permitted to flow to a property determining cell when the second cell has been filled to a predetermined volume, and simultaneously the water is prevented from flowing to the second cell while it is now permitted to flow to the first cell.

    摘要: A layer of titanium carbosilicide Ti.sub.3 SiC.sub.2 on a silicon carbide surface polished for making a joint makes it possible to join silicon carbide bodies together in a hot pressing procedure and obtaining a joint strength comparable to the strength of the silicon carbide material. Such a layer on silicon carbide also makes possible brazed juoints with steel alloy or nickel based alloy parts. The layer may be applied directly by a powder dispersion in a volatile but viscous glycol or by sputtering or else the layer can be made in place from a powder mixture of components, especially TiC.sub.0,8 and Tisi.sub.2 (5:1) or a titanium layer of a thickness in the range of 1 to 3 .mu.m that reacts with the silicon carbide surface. When silicon carbide parts are joined together, the heating up to make the joint also serves to convert a titanium layer into titanium carbosilicide. When silicon carbide is to be joined with metal, a preliminary heating step is necessary to at first convert a powder mixture or a titanium layer on the silicon carbide surface to Ti.sub.3 SiC.sub.2. Alternatively a Ti.sub.3 SiC.sub. 2 surface layer can be formed by a sputtering process. The Ti.sub.3 SiC.sub.2 layer favors brazing of the metal part to the silicon carbide surface as treated. The heating requires reaching a temperature in the region from 1200.degree. to 1600.degree. C. for periods between a half hour to about three hours in the presence of a reducing protective gas.

    摘要: A magnetic field sensor comprises a stack of ferromagnetic layers advantageously separated by an intermediate layer of proper material and so arranged that the ferromagnetic layers are with one component in an antiparallel magnetization direction. The sensor is provided with terminals for passing an electric current through the stack and for detecting a voltage drop across the stack. The magnetic resistance change with such a stack is substantially greater than in systems which do not provide an antiparallel magnetization or do not have the intermediate layer.

    摘要: A method of and an apparatus for generating a control frequency in which two submultiples of a frequency standard are obtained which differ by unity in the respective frequency division and are mixed so that the contribution of a prior control frequency is reduced form period group to period group while the contribution of the new control frequency is increased from period group to period group. The system provides fine control of frequencies for, for example, driving synchronous motors without requiring excessively high frequency standard oscillators.

    摘要: A treating process for the separation of coated nuclear fuel particles from a graphitic matrix in which the nuclear fuel particles are embedded, which is employed in an installation for the conditioning of graphitic fuel elements of high-temperature nuclear reactors. The graphite which encompasses the nuclear fuel particles is conducted away through the action of a brush which isolates the nuclear fuel particles together with their coatings or the nuclear particles themselves, and wherein the nuclear fuel particles which are contained in the brushed product are then separated from the comminuted graphite. The nuclear fuel particles are worked out of the graphitic matrix through the action of the bristles of the brush which conduct the graphite away, but in which the coated nuclear fuel particles when they are contained within hard coatings or the nuclear fuel particles themselves, remain preserved. The worked out nuclear fuel particles are separated from the comminuted graphite fraction through the delivery of the brushed product into a sifter which is passed through by a separating gas, and in which the fine-grained fraction is conveyed away together with the gas stream.

    摘要: An ionization chamber of reduced size, with an end window of a diameter preferably smaller than 3 cm is mounted on the end of a hand probe containing an amplifier, the output of which goes through a cable to an indicating device. One of a set of aperture diaphragms may be slipped over the end window to reduce the area of the window transparent to beta rays. In addition to the end window, slots in the cylindrical wall of the chamber increase the solid angle through which radiation may enter the chamber. The end window and the slotted walls of the chamber are covered with tissue-equivalent material for measurement of radiation exposure dose by the electrodes of the chamber and their associated amplifier and indicator. An alternative design with a conical chamber and conical inner electrode and a smaller window provides reliable measurement, even in inhomogeneous radiation fields without the necessity of using diaphragms.

    摘要: The invention is concerned with an electrochemical gas analyzer for determining the sulphur dioxide content of certain gases in particular, flue gases. The device comprises a measuring cell containing a measuring electrode for the determination of the depolarization current and further comprising an unpolarizable electrode in the same electrolyte. The gas input flow is utilized to cause a circulation of electrolyte containing the dissolved gas which moves in the space between the measuring and counter-electrode. The electrolyte is continuously renewed and the electrolyte leaving the cell is regeneratd and recycled. The sulphur dioxide dissolved in the electrolyte is removed outside the cell by treatment with air in the presence of activated charcoal.
