Patent DE-3306601-A1 (DE)
Title: Process for the improvement of the efficiency of gas turbine heat and power plants
Inventor: SCHUBERT JOHANNES PROF DR ING
IPC: F02C3/34
Filed: 1983-02-25
Abstract: The low efficiency of a simple gas turbine heat and power plant is to be attributed to high exhaust gas losses. The exhaust gas losses are drastically reduced when the excess air in the combustion chamber is predominantly replaced by flue gases from the waste heat boiler and only that amount of fresh air is introduced into the combustion chamber which is required for the combustion for increasing the temperature and for ensuring ignition and combustion. The current characteristic can fall slightly as a result of this.

A square deflection part and a square connection part are arranged so as to run in parallel and in a straight line, while the deflection part exhibits elevations which have the same diameter and are in the shape of a full semi-circle or quarter-circle. At the points of the smallest mutual spacing, said elevations in each case approximate a distance which corresponds to the width of the grooves.
Patent DE-3403807-A1 (DE)
Title: Shuttle
Inventor: PRINCIPE VICTOR
IPC: D05C11/18
Filed: 1984-02-03
Abstract: The tension of the shuttle yarn of a shuttle for shuttle embroidering and quilting machines is regulated by a spring plate (3) on the cover (2). The exact yarn tension depends essentially on the position of the spring plate (3). A boss (8) arranged on the cover (2) engages through a long hole (7) in the spring plate (2) when the latter is in the correct operating position. This solution on the one hand allows a simple cleaning of the spring plate without deformation and on the other hand guarantees exact positioning, even under the influence of vibrations of the spring plate (3) which are caused by the movements of the shuttle (1) and by the yarn-thickness differences in the shuttle yarn. <IMAGE>

Title: Can lid transporting apparatus
Inventor: LAUCKNER GERHARD
IPC: B65G47/68
Filed: 1984-04-13
Abstract: In a can lid transporting apparatus for transporting can lids (5) from a drying oven via two conveying tracks (1, 2), in the course of which an uprighting device (4) stands the can lids (5), which are transported from the stove horizontally, upright and packs them against one another standing upright on their edges, to a lid batch gripping device (11) which takes hold of the batches of lids, situated on the two conveying tracks (1, 2), once they have been divided as appropriate under the control of limit switches (10), and loads them into a transporting container, asymmetries in the number of can lids (5) on the two conveying tracks (1, 2) due to malfunctions can be equalised by means of two transfer devices (12) which each point from one conveying track (1, 2) to the other and which transfer can lids (5) controlled by the limit switches (10) from one conveying track (1, 2) to the other upstream of the uprighting device (4). <IMAGE>
Patent DE-3415046-A1 (DE)
Title: Coupling device
Inventor: HENGSTLER ROLF
IPC: F16D43/26
Filed: 1984-04-21
Abstract: The invention relates to a coupling device for connecting a gear mechanism switchable by electric motor into two directions of rotation to a shaft which can be switched alternately into two defined angular positions. Arranged between a gear mechanism output and an actuating shaft (18) is a driver (21) comprising two sprung pawls (19, 20). By virtue of the action of a spring (27), the pawls (19, 20) assume a splayed, fork-like position relative to one another and are connected to the actuating shaft (18) via a common driver pin (29). An axially projecting pin (22) on the gear wheel (16) on the output side of the gear mechanism (1) in each case engages the leading pawl (19 or 20) in the driving direction and sets the actuating shaft to the right-hand or left-hand position. The solution ensures that a defined angular rotation can be assumed at the gear mechanism output even though no precisely defined angular travels are available at the gear mechanism input. The invention can be used, for example, for the alternate switching of a rotary switch into the on and off positions by electric motor. <IMAGE>

Title: Method for determining the wall thickness of a workpiece and/or the sound velocity in a workpiece, and device for carrying out the method
Inventor: GEBHARDT WOLFGANG DIPL PHYS DR
IPC: G01B17/02
Filed: 1984-07-13
Abstract: A method for independently determining both the sound velocities of ultrasonic waves and the wall thickness of plane-parallel or parallel- curved components by means of V transmission makes use of directional variation of the acoustic axes in the case of antenna arrays by varying the signal frequency or by varying the phase difference between adjacent individual antennas. The measurement arrangement consists of an array of transmitting and an array of receiving antennas (3, 4) which are subdivided for their part into two transmitting antenna arrays (5, 6) and two receiving antenna arrays (7, 8). Synchronous pivoting of the acoustic axes of the antenna arrays (5, 7) is used to search for the maximum received signal. In a second step, use is made of synchronous pivoting of the acoustic axes of the antenna arrays (6, 8) likewise to search for the maximum received signal. The sound velocities and the wall thicknesses of the workpiece (1) under test are determined by a computer from the two signal frequencies or phase differences corresponding to the maximum received signals. <IMAGE>

Title: Automatic gambling machine with a symbol gambling device and a winnings display ladder
Inventor: GAUSELMANN PAUL
IPC: G07F17/32
Filed: 1984-07-18
Abstract: For an automatic gambling machine comprising a symbol gambling device (1) controlled by a random-number generator (4) and a control device (3), which displays a symbol combination deciding on winning or non-winning before the end of the game, with a processor (5) which determines a winnings signal representing the magnitude of the win from the random number, by means of which the control device (3) activates one of a number of winnings-individual display elements (8), the latter being combined in strictly monotonic sequence of winnings to form a winnings display ladder (10), it is proposed that the processor (5> - transforms equally distributed random numbers into random numbers of predetermined distribution, - selects, in accordance with the predetermined distribution, a winnings signal from a set of winnings signals which comprises the winnings signal determined and a group of higher-valued winnings signals and that the control device (3) has activated, at the end of the game, the display element (8) to which the magnitude of the win of the selected winnings signal is allocated. The automatic gambling machine according to the invention can increase the winnings achieved without the gambler suffering losses. The associated increase in payout remains within a calculable and economically supportable frame, the calculability of the increase in payout being based on the predetermined distribution in the transformation of the initially equally-distributed random number. <IMAGE>
Patent DE-3427552-A1 (DE)
Title: Method for cross-correlation-free bit error rate measurement in quadrature-modulation systems by means of a pseudo-random binary signal string
Inventor: BESSAI HORST DIPL ING
IPC: H04L1/24
Filed: 1984-07-26
Abstract: In pseudo-random binary signal strings (PRBS) which are split in quadrature amplitude modulation (QAM) into two binary sub-streams, the cross-correlation components unexpectedly occurring there which render correct bit error rate measurement impossible are already eliminated at the output of the pseudo-random binary signal generator. For this purpose, the PRBS to be fed to the QAM system is first split into two binary sub-strings with double the pulse period 2 T, the sub-strings are scrambled differently from one another and then re-combined to form a new PRBS before being split once more in the known quadrature amplitude modulation. A PRBS pre-processed to this extent has the statistical independence required for bit error rate measurement. The scrambling at the transmitting end is reversed once more at the receiving end by two corresponding descramblers. For correct synchronisation of the descramblers, the descramblers are switched via a changeover switch to the respective other output of a series-to-parallel converter connected upstream in the bit error rate measuring device at the receiving end if a bit error rate is indicated at the receiving end which is clearly too high (Fig. 3). <IMAGE>
