Patent DE-3242713-A1 (DE)
Title: Inlet housing for a steam turbine
Inventor: PUZYREWSKI ROMUALD PROF DR
IPC: F01D9/04
Filed: 1982-11-19
Abstract: In a single-inlet high-pressure steam turbine, the inlet housing is designed from two spiral housings (1, 2) which loop into one another. These spirals have annular openings (1', 2') which point towards the blade inlet, are arranged concentrically and extend over 360 DEG  of the circumference. Reduction pieces (6, 7) in which the steam flow is accelerated are provided on the spiral inlets (1'', 2''). The spirals can be shut off and/or throttled so that the reaction blades (13, 14, 15) can be subjected to a continuously variable partial flow. <IMAGE>
Patent DE-3244784-A1 (DE)
Title: Toe iron of a ski binding
Inventor: UNGER PAUL
IPC: A63C9/00
Filed: 1982-12-03
Abstract: The invention relates to the toe iron of a ski binding, which allows lateral release by swivelling the sole-holder part in the horizontal plane. Furthermore, the sole-holder part can be moved upwards. A spring arrangement acting on the sole-holder part is preferably provided. When the ski boot is tilted laterally, in order to prevent jamming and thus increased friction resistance between its sole edge and the top of the ski and the sole-holder part, the sole-holder part (13) is displaceable by a limited stroke path (h) in a direction approximately perpendicular to a housing part of the toe iron (8). Furthermore, an arrangement is provided between the sole-holder part and a component fixed to the ski. In the case of a particular, laterally pressing force component of the boot and, furthermore, an upwardly pressing force component of the boot, said arrangement converts the latter force component into a torque acting additionally laterally on the toe iron. The arrangement simultaneously releases the upward vertical movement (h) of the sole-holder part. <IMAGE>

Title: Compensation joint, in particular for steering spindles in motor vehicles
Inventor: METTLER KARL
IPC: B62D1/16
Filed: 1982-12-28
Abstract: Steering spindles for motor vehicles require at least one compensating joint. In small cars, the mounting parts are in this case to be as small and as inexpensive as possible without, however, any negative influence on their safety and reliability as a result. The compensating joint provided for this has, in the manner of a cardan joint, cross joint or ball joint, two forks (1, 2) and a joint intermediate part (5). In this case, four joint pins (7-10), which are offset in a plane by 90 DEG  in each case in relation to one another and are received by bearing bores (6) of the joint parts, are present. The diameter (D) of the bearing bores (6) is in this case considerably greater than the diameter (d) of the joint pins (7-10). The hollow cylindrical interspace thus recessed is filled with an elastomeric material (11). Furthermore, the joint pins (7-10) are designed as a one-piece part made by extrusion. This part is used in its shape which is obtained exclusively by extrusion without any further shaping working. The forks (1, 2) of the joint also are expediently formed by extrusion. The angular divergence which can be taken up by this joint is approximately 10 DEG  and is completely adequate for this purpose. <IMAGE>

Patent DE-3310074-A1 (DE)
Title: Hollow block
Inventor: WOCHNER KURT
IPC: E04B2/42
Filed: 1983-03-21
Abstract: A hollow block, designed symmetrically in relation to a central plane, with chambers which pass through it in the height direction, is designed in such a manner that, on its end sides, chambers, which are half as wide as those inside the block, end in an open manner. If, in the assembly of a wall or of a wall element, such blocks are according to position offset by half a width, consequently chambers, which are formed by the open half chambers at the abutting end sides of the blocks, lie in a fitting manner over chambers present inside the blocks, so that cavities are created which pass vertically through the walls or wall elements, which cavities can be foamed continuously but can also be used for passing through reinforcement irons which are possibly to be cemented or foamed in or for accommodating lines of all types. Cold bridges formed by mortar layers can thus be avoided so that especially good insulation values can be achieved. Expediently, the blocks contain along each of their side surfaces one chamber series and, in between, a third central chamber series, the chambers of the central series being half as wide as those of the outer series. Blocks of half depth can advantageously be used as ceiling limitation and in the sealing of ceilings as form replacement; the external layer of the wall is thus obtained in the same material. <IMAGE>

Title: Drive for reciprocating and rotary motion
Inventor: DAUME ACHIM DIPL ING
IPC: F01C9/00
Filed: 1983-03-25
Abstract: The invention relates to a drive which can be driven pneumatically or hydraulically The piston itself moves in an annular channel and drives a handwheel directly. The drive shaft is situated in the centre of the handwheel and is connected to the handwheel via spokes. Depending on the pressurisation, the handwheel can perform a partial rotation in the anticlockwise or clockwise direction and the shaft is rotated in a corresponding manner. If reciprocating movements are to be produced, a sliding block is mounted on one spoke and the reciprocating motion is taken off via a joint. The reciprocation travel can be increased or reduced by displacing the sliding block.

Title: Starting time limitation for internal combustion engines with fuel injection
Inventor: GAESSLER HERMANN
IPC: F02D41/06
Filed: 1983-06-21
Abstract: Circuits are described for starting time limitation for internal combustion engines with fuel injection. During the starting process the mixture is enriched as usual, but once the freely selectable starting time limit has expired the enrichment is prematurely switched off. Unavoidable interference pulses and the voltage ramp on completion of the starting process, characteristic of certain types of starter, can no longer lead to a further mixture enrichment and hence to overrich running of the internal combustion engine. This is made possible by an additional monostable circuit, which is set on starting and is automatically reset on completion of the starting time limit duration. The starting time limiting circuit is especially suitable for motor vehicles with an injection engine. <IMAGE>

Title: Process and apparatus for the continuous anaerobic degradation of organic compounds
Inventor: AIVASIDIS ALEXANDER DIPL CHEM
IPC: C02F3/10
Filed: 1983-12-17
Abstract: The continuous anaerobic degradation of lower carboxylic acids and/or furfural and/or methanol in aqueous liquid, in particular of acetic acid, is carried out according to the invention in a column reactor having a fixed bed composed of a support, in particular anthracite, colonising microorganisms with admixture of recycled reactor effluent in an amount such that virtually uniform conditions are present in the reactor and the pH measured at the top and bottom of the reactor does not differ by more than 0.3 pH units. The space-time yield in this case can, surprisingly, be considerably increased if, after culture of sufficiently adhering microorganisms at a residence time >/= 50% of the generation time, an iterative shortening of the residence time (preferably by about 30% of the preceding value) is carried out with establishment of equilibrium in each case, until the space-time yield can no longer be increased.
Patent DE-3347114-A1 (DE)
Title: Method and device for recognising and, if necessary, replacing an m-bit synchronisation word preceding a digitised image content of n  APPROX  10<6> bits
Inventor: LOHMANN KLAUS DIPL ING
IPC: H04N5/04
Filed: 1983-12-27
Abstract: During the transmission of digitised image signals in data packets of n  APPROX  10<6> bits and only one m-bit synchronisation word per frame, the risk of synchronisation to pseudosynchronisation words accidentally produced by the image content arises, in addition to the risk of transmission errors in the synchronisation word itself. To avoid both risks, a vertical identification signal VK1 is extracted from the m-bit synchronisation word with m > 10 transmitted in the vertical blanking interval of k  APPROX  10<3> bits. This identification signal starts an n-bit counter 7 and disables a gate circuit 5, 6, previously opened for the period of o-bits (m < o < k) of the assumed occurrence of the vertical identification signal VK1 by the preceding frame end pulse of this counter, with respect to pseudo-identification signals which can be accidentally extracted from the image content. An o-bit counter 10 started by the frame end pulse replaces with its output pulse VK2 a failed vertical identification signal VK1. After the vertical identification signal has been lacking several times, a p-bit counter 11, operated by the frame end pulse and in each case reset by the vertical identification signal VK1, inhibits its replacement by the output pulse of the o-bit counter.
Patent DE-3401381-A1 (DE)
Title: Hydraulic control device
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/662
Filed: 1984-01-17
Abstract: A hydraulic control device for controlling the adjustment of the two pairs of cone pulleys of a continuously variable cone pulley transmission connected to the output side of a drive engine for a vehicle, especially a passenger motor vehicle, has a control valve which has a control piston alternately admitting pressure medium to the actuating cylinders of the two pairs of cone pulleys. In order to achieve a favourable adjustment characteristic of the cone pulley transmission in such a way that high rates of adjustment are initially achieved in response to the vehicle driver's desire for greater load variation and low rates of adjustment are achieved in proximity to the design control speed of the engine, it is proposed that a shut-off valve (6), controllable as a function of the position of the control valve (4), be connected into the respective pressure admission lines (11, 12) leading to the actuating cylinders (1, 2) of the pairs of cone pulleys. In addition a bypass line (11b, 12b) bypassing the respective shut-off valve (6) and with a fixed restrictor (13) arranged in it for the delayed supply of pressure medium to the actuating cylinders (1, 2) is provided, which bypass lines become operative if the pressure admission lines (11a, 12a) leading directly to the actuating cylinders (1, 2) are shut off. <IMAGE>

Title: Position data input device which can be moved freehandedly for electronic data processing systems (technical term: computer mouse) with mechanical/optical or mechanical/magnetic detection of the motion vector
Inventor: JAEKEL-FESSENMAIER CHRISTIAN D
IPC: G06F3/0354
Filed: 1984-02-28
Abstract: A computer mouse is used for transmitting commands to a computer. For this purpose, the computer mouse is moved freehandedly on a level base, the motion vector is transmitted to the computer and acknowledged by corresponding movement of a screen cursor. To keep down the number of moving mechanical paths, which are susceptible to wear and interference, on the one hand, but also not to be dependent on a specially prepared (patterned) base, a tracker ball is used which rolls on the base and thus reflects the motion process when the computer mouse is moved. This tracker ball is provided with an optically or magnetically (inductively) readable pattern so that its movement can be scanned contactlessly by appropriate sensors. The only moving mechanical part is thus the tracker ball itself.
