Abstract: Contaminants of oil fillings of technological units using oil as a cooling, lubricating, insulating, or power medium, are removed by periodically applying a separating working cycle and a pressure working cycle in a vessel connected with the oil system of the technological unit, and returning the cleaned oil to the oil system of the unit. In the course of the separating working cycle, gaseous and liquid contaminants in the vessel are brought to boiling by under-pressure generated by a reversible pump; a gas-liquid cushion created thereby above the oil surface in the vessel is displaced from the vessel in the course of the following pressure working cycle, which is caused by the reverse action of the pump, while the cleaned oil is returned to the oil system of the technological unit. Both cycles are repeated as often as required to clean the oil to the desired degree.

Abstract: The vane arms are slats (C) set either vertically or horizontally (D). Outside the vertical shaft (A) is positioned the shaft for the rotor which is hollow. Between the two shafts is placed grease, and on the vertical shaft (A) is a bowl-shaped surface in which a steel ball is held in reserve (Y). This serves to form an air bearing providing the least possible resistance to rotation. To prevent the grease from sinking away, the tube interior is tapped with a scoop effect toward the bottom (M), and this causes the grease to move upwards during rotation. - Where the slats ar slightly bowl-shaped, they are adjusted tightly when the wind comes in contact with them, and rotates between two points (X to B). They then open as the vane arms turn outwards in a half-closed bowl-form casing which at the front has an inclined wind captation unit. At the air outlet is a control rudder.

Abstract: The stencil (3) is pressed against the printing table (2a), with pressure being thus applied to a material (6a') located between them. The frame (4) works in conjunction with a gripper (9) which secures the material front end part, and during the printing sequence raises the frame front end to permit an adequate release angle to be formed between the stencil and the material. With pressure applied to a soft, pliant material (6'), the gripper releases at the commencement of the printing sequence without working in conjunction with the material front end part. A vacuum is applied to the printing table which fixes the material against it. The material moves with the printing table away from the stencil, obtaining an adequate release angle, so that its front end part is transferred to a transport belt (15).

Abstract: A method for reducing the influence of distortion products that are formed in conjunction with the analogue-digital-conversion (14,15) of samples of an electric signal (IF), from which signal two quadrature signals (I,Q) are formed prior to the conversion process. The quadrature signals are phase modulated (16-20) prior to the conversion process and are phase demodulated (20-22) subsequent to this conversion process, by phase-shifting the signals by a value ( phi n, - phi n) which is changed randomly for each new sample. The energy content of individual distortion products is distributed over a broadband in this way. This is due to correct demodulation of the useful signal, i.e. the fundamental tone, whereas harmonics and intermodulation products will have a residual phase modulation subsequent to the phase demodulating process. <IMAGE>
