Abstract: A pressure electrolyzer having an electrolytic cell block that contains a number of electrolytic cells combined to form a stack, each electrolytic cell having an anode and a cathode. The electrolytic cell block has a sealed housing formed by a number of stacked cell frames of the electrolytic cells, the cell frames being composed at least partially of a material that is elastic at least in a longitudinal direction of the electrolytic cell block and seals adjacent cell frames from each other. End plates are provided so as to hold the electrolytic cell block in place between the end plates under compression of the elastic material. Each of the cell frames has a rigid element that runs in a circumferential direction of the frame so as to mechanically stabilize the cell frame. The rigid element being connected with the elastic material and forming a shell-like frame structure, which partially encloses the elastic material so that the elastic material partially protrudes from the rigid element to form a compressible region in the longitudinal direction of the electrolytic cell block. Adjacent cell frames each have projecting parts and recesses that fit into each other for locking the adjacent cell frames in place and/or for sealing the adjacent cell frames.

Abstract: When using phase control of semiconductor valves (4) for controlling AC voltage converters, in order to regulate the power factor it is necessary to determine the phase angle between the current I and the voltage U by measuring the time difference between the points at which the current and voltage pass through zero. However, disturbances superimposed on the mains voltage cause considerable random fluctuations, particularly in the measurement of the times of the voltage zero-passages, which are transferred to the phase angle and can result in an unstable regulation characteristic. It is therefore proposed according to the invention to make use of a reference time for the voltage zero-passage when determining the time difference, which reference time is derived from the measured values for the true times of the preceding voltage zero-passages.

Abstract: For rapid soldering operations at small soldering points, it is necessary to use a fast, contact-free temperature measurement method. In principle, an infrared radiation pyrometer is suitable for this purpose. A disturbing effect in this temperature measurement method is the variation in the emission coefficients from one soldering point to another. According to the invention, this disadvantage is eliminated by calibrating the infrared radiation pyrometer in the course of each soldering operation on reaching a fixed temperature point detected by suitable measurement methods and situated within the temperature range of the method individually for the respective soldering point using previously determined calibration curves. To control the soldering point temperature in accordance with a specified temperature/time cycle, the control circuit is constructed from the infrared radiation pyrometer and the laser, whose power can be controlled. This temperature control method is insensitive to the variations in the volume of solder and the emission factor of the soldering points.

Abstract: To obtain an improved PAL-compatible television system with reduced crosstalk between luminance and chrominance spectra, which can be adapted to existing terrestrial channels, the luminance signal spectrum is split on the emission side into a low-frequency part Y1 and a high-frequency part Y2 which is modulated onto a carrier. This modulation is effected in such a way that the spectrum of the resultant modulation signal Y*2 lies in a region of the three-dimensional PAL spectrum which is virtually free of useful signal spectra within the given channel width. The modulation signal Y*2 is transmitted with the low-frequency par Y1 of the luminance signal spectrum in the form of data concerning the luminance Y in the PAL-C signal. On the reception side, an improved television receiver filters out the modulation signal Y*2 from the received PAL-C signal and demodulates it. The signal so obtained, which corresponds to the high frequency part Y2 of the luminance signal spectrum, is added to the low-frequency part Y1 of the luminance signal spectrum separated from the received PAL-C signal. A conventional PAL receiver processes only the low-frequency part Y1 of the luminance signal and is not subject to interference by the modulation signal Y*2 transmitted with the latter.

Abstract: The invention relates to a process and apparatus for preparation of treatment gas used in heat treatments, whereby the treatment gas is produced in a furnace disposed catalyst retort at a temperature of that of the furnace in which the retort is positioned. With such processes, when using lower furnace temperature ranges, problems occur with respect to the reaction of the feed gas in the catalyst retort. To provide an improvement, the catalyst retort in the furnace is surrounded by a shield, and the treatment gas generated in and leaving the catalyst retort is first fed into a space defined by this shield and thereafter released into furnace space. By this, an isolation of the catalyst retort from the interior of the furnace is provided, and relatively higher retort temperatures are available.

The other functional substituent is an isocyanate group which reacts off, e.g. under the effect of moisture. These different reaction mechanisms enable the reactive contact adhesive to be cured in stages, e.g. by forming contact-sensitive adhesive layers on hard surfaces in a first stage, subsequently fitting the correspondingly coated surfaces together and firmly bonding them together in a final stage, e.g. under the effect of atmospheric moisture. Also provided is a process for the production of the new reactive contact adhesives.
