Abstract: Method and device for interference cancellation. A radio access unit comprises a plurality of directionally separated antenna elements (41k, k=1, 2, . . . , L) for receiving signals transmitted by a plurality of remote units. From signals received by each of the antenna elements (41k) first weighing factors (g(1)k) are determined (49), for optimally selecting signal of a first remote unit (521). A first radio signal (s1) of the first communication unit (521) is provided by weighing (44) the received signals using the first weighing factors (g(1)k). For a further radio communication unit (52i) further weighing factors (g(i)k) are determined. A corrected further radio signal (s'i) is provided each time by subtracting (46) from the further radio signal (si), previously obtained corrected radio signal (S'i-1, S'i-1, . . . ) weighed by the further weighing factors (g(i)k), till a stop criterium has been satisfied.

Abstract: A pressure gas generating system including the compressor which is switched to a no-load condition when a predetermined pressure level is reached. The system employs either a regulator or a governor to allow the free exchange of gas between the suction chamber and the compression chamber to prevent the development of high temperatures. In the pressure regulator control system, the opening of the discharge valve is enlarged and is vented into the atmosphere by the pressure regulator so that the compressor continues to operate with reduced drive power and generates less heat during the no-load condition. In the pressure control system, the pressure discharge valve as well as the suction valve are opened during the no-load condition.

Abstract: A bellows-like hollow member formed of gathered tubular sheathing material, for processing, especially as a peel-skin for the production of small sausages, produced as follows: polypropylene with copolymers is extruded in a smooth foil of three inseparable layers, of which the middle layer is stronger and the two outside layers have a lower melting point. The foil is then stretched to increase its strength, and is formed into a tube with a lengthwise seam along its entire length, formed by overlapping and consolidation of its lengthwise edges. Finally, the tube is gathered bellows-like forming a plurality of folds and forming hollow member, and is simultaneously rotated around its axis so that the lengthwise seam produces a helical path. The tubular sheathing which is obtained by this gathering is of inexpensive material, can be easily peeled from the boiled meat emulsion, can be used without difficulty in sausage machines, and is not sensitive during storage to moisture and high temperatures.

Abstract: An airless paint sprayer includes an outlet check valve assembly having a dual spring configuration which allows for increased fluid flow through the valve without diminishing response time of the valve or the priming operations of the system. One of the springs is not engaged when the valve is closed and the other spring has a much lower spring rate and biases the valve toward a closed configuration when the valve is open, closed, and all positions therebetween. The dual spring configuration accommodates highly viscous fluids or paints with maximum fluid flow and no detrimental impact on the priming operations of the sprayer.
