Patent DE-3146346-A1 (DE)
Title: Method of regulating the fermentation temperature and fermentation-temperature regulator for implementing the method
Inventor: HAIGES HELMUT
IPC: C12G1/028
Filed: 1981-11-23
Abstract: For regulating the fermentation temperature of a must situated in a container with a cooling-water sprinkling arrangement, the actual value of the fermentation temperature is compared at predetermined time intervals with an adjustable desired value and in the event of a deviation of the actual value from the desired value upwards a valve controlling the cooling-water outlet from the cooling-water sprinkling arrangement is opened automatically for a period of time which in its length depends upon the deviation of the actual value from the desired value. The regulator for implementing the method has an actual-value transmitter (7) for the temperature of the must in the form of a completely encapsulated temperature-dependent resistor, a manually adjustable desired-value transmitter for the desired value of the must temperature, an actual-value/desired-value comparator, a clock unit which, in the cycle predetermined by it, triggers an inquiry of the actual-value/desired-value comparator, and an output stage which, depending upon the size of the deviation of the actual value from the desired value, generates an output signal for driving a solenoid valve (5). <IMAGE>
Patent DE-3151043-A1 (DE)
Title: Method and arrangement for reducing at the transmitting end the twelve-fold uncertainty of the carrier phase of a 16-QAM signal occurring at the receiving end
Inventor: BESSAI HORST DIPL-ING
IPC: H04L27/34
Filed: 1981-12-23
Abstract: The invention achieves a reduction at the transmitting end of the twelve-fold uncertainty of the carrier phase of a 16-QAM signal, composed of a normal and quadrature signal, occurring at the receiving end. For this purpose, when the highest amplitude step (4) occurs simultaneously in the four-step normal and quadrature signal, both signals are amplified to a further fifth amplitude step (5) which marks the nominal value of the carrier phase with the amount DELTA  u  2ROOT 2 as fourth amplitude step of the otherwise three-step 16-QAM signal after the quadrature modulation. In principle, each of the four corner points in the signal state diagram can mark the nominal value of the carrier phase as fourth amplitude step of the 16-QAM signal sent out. The corner point with the Gray-coded 4-bit word 1010 located in the first quadrant of the signal state diagram is preferably used. To carry out the method, the logic of the binary/quaternary converters for the normal and quadrature signal at the transmitting end, which are necessary in any case, is supplemented by an AND gate and two subsequent resistors (R1). <IMAGE>

IPC: A61M5/165
Filed: 1982-02-13
Abstract: A plastic filter designed as a disposable unit, in particular for infusion and transfusion solutions, has an essentially rectangular plan shape. The membrane elements (15) enclosed therein have a harp-like support frame (6) in the interior, adapted to the essentially rectangular outline of the housing (1.2), which support frame on each of its flat sides is connected to a hydrophilic membrane section (5, 5'). The longitudinal ribs (8) of the support frame (6) point in the direction of the housing outlet (4), each free space (7) between two longitudinal ribs (8) joining an outlet channel (11) in the outlet chamber (17) and both membrane elements separating the inlet chamber (16) from the outlet chamber (17) in a fluid-tight manner. The support frame (6) has, perpendicular to the longitudinal axes of the ribs, a biconvex cross-sectional shape, or the edge regions have wedge-shaped bevels. Two hydrophobic venting membranes (13) are arranged in the upper part (1) of the housing and are upstream at the outer end of the inlet chamber (16). The venting (12, 13) of the inlet chamber (16) can also be carried out by a hydrophobic, porous (sintered) region of the housing itself. With two membrane elements (15) having four membrane sections (5, 5') a very large filter surface area and high filtration efficiency are achieved despite small housing dimensions. <IMAGE>

Patent DE-3316193-A1 (DE)
Title: Removal of a first metal sheet secured to a second metal sheet by spot welding
Inventor: HABERER HORST
IPC: B23B51/02
Filed: 1983-05-04
Abstract: A first metal sheet secured to a second metal sheet by spot welding, for example in motor vehicle bodies, can be removed by drilling through the first sheet in the region of the welded spot around the latter until the second sheet is reached. First of all the middle of the welded spot can be drilled with a corresponding tip (2) of a drill (1) and during further drilling the external region of the area of sheet to be removed can be cut. When the outer cutting region meets the second sheet, the drill tip can already have penetrated the latter so that the drill is centred and guided also in this phase. When the first sheet has been cut through with the outer cutting region, the remainder of the sheet can be removed. In this case it is sufficient for the drill tip (2) to project beyond the lateral cutting edges (4) of the drill (1) by roughly the thickness of the sheet to be removed. <IMAGE>
