Abstract: The invention concerns the method and arrangements for registering and playback of video information in the form of a frequency-modulated signal on an information storage element. By using the registering method and an apparatus for implementing it, video information in the form of a frequency-modulated signal 92 is stored on the information storage element 10, having its information content in the form of a carrier signal with frequency changes over time, which vary from a centre frequency. The frequency-modulated signal 92 occurs as a linear sequence of first and second markings 38 situated in track-like manner on the storage element's surface 24. In a preferred embodiment of the invention, the linear sequence of first and second markings 37, 38 is in alternating relationship. The first type of markings reflect light in non-specular manner. The second type of markings reflect light in specular manner. The length of the specular light-reflecting regions and the non- specular light-reflecting regions represents consecutive half-periods for each whole period of a frequency- modulated signal. The length of these regions varies in inverse proportion to the momentary frequency of the frequency-modulated signal. In this way, the length of the specular light-reflecting and the non-specular light- reflecting regions is a representation in space of the frequency-modulated signal. <IMAGE>

Abstract: In an indirectly heated, gas-fired furnace (10) for the heat treatment of metal material in an atmosphere of processing gas consisting predominantly of nitrogen, the processing gas is produced using the heating exhaust gases as the principal raw material. The exhaust gases are cooled, filtered and freed of carbon monoxide and water vapour, whereupon a small amount of air is added to impart a predetermined value to the oxygen content and a controlled amount of liquefied petroleum gas or other hydrocarbon gas is added. A processing gas consisting predominantly of nitrogen, hydrogen and carbon monoxide is produced by thermal cracking of the liquefied petroleum gas in a catalytic reactor (25) and fed to the furnace (10). If a processing gas free of carbon and consisting predominantly of nitrogen and hydrogen is required, the reactor (25) may be replaced by a deoxo reactor into which the exhaust gases, after their oxygen content has been adjusted, are fed together with a controlled amount of hydrogen gas.

Abstract: A method for controlling a converter in an HVDC power transmission system and a converter with appropriate control means for carrying out said method. The current regulator influences the control angle of the converter in dependence on the difference (I0-Id- DELTA I) between, on the one hand, the measured current (Id) and, on the other hand, the current order signal (I0) decreased by a current margin value ( DELTA I), controlling the converter with a control angle which is dependent on the one hand, on a proportional component being linear proportional to said difference and, on the other hand, on an integral component corresponding to the time integral of said difference. The current regulator has a proportional regulator part (PR) and an integrating regulator part (INT1). The output signal of the integrating regulator part is limited in the upward direction to a value corresponding to a maximum value of the control angle of the converter. The output signals from the integrating and the proportional regulator part are added to form the output signal of the current regulator. The limiting value of the integrating regulator part is calculated by a calculating circuit as a function of the current order and the ideal direct voltage of the converter. The calculation is made by determining the control angle at which, at a load current equal to the current order, the extinction angle becomes equal to the smallest permissible turnoff angle. From this angle there is then subtracted the output of the proportional unit at a current equal to the current order, and the result constitutes the limiting value for the integrating regulator part.

Abstract: A hydraulic cylinder (1) with a piston (5) made completely or partially of electrically conductive material comprises at least one opening (19, 20) for the mounting of an electric position indicator (21, 22). The openings (19, 20) are closed in a liquid and pressure-proof manner towards the interior of the cylinder (1) by means of circular plate-shaped bodies (17, 18) glued to the inner surface of the cylinder (1). As the plate-shaped bodies (17, 18) are made of a ceramic material, preferably steatite, they may allow passage of the magnetic field transmitted from the electric position indicators (21, 22). The openings (19, 20) are adapted in the end covers (2, 3) of the cylinder (1) for the determination of the end positions of the piston (5). Furthermore the cylinder may be provided with piston-braking means in the form of seal rings (12, 13). As the piston (5) penetrates the magnetic field, an altered signal indicating the position of the piston (5) will be transmitted from the electric position indicator, which is preferably an inductive sensor. Very narrow inductive sensors being used it is now possible to built these into even very small hydraulic cylinders, so that these inductive sensors can be built into hydraulic cylinders of all sizes without being influenced by the high pressure of the cylinders. The hydraulic cylinder (1) according to the invention may even be manufactured in a very inexpensive and simple manner, and by building in the inductive sensors a previously unknown exact and reliable determination of the positions of the piston may furthermore be obtained.
