Title: Radiation protection wedge
Inventor: KULLMANN WILTON
IPC: A61N1/16
Filed: 1988-04-12
Abstract: In all the cases in which the harmful earth radiation cannot be avoided by moving to another place, changing the function of the room or repositioning the furniture, it is possible to install one or more radiation protection wedges in order to make the entire house area free of radiation. The earth radiation is reflected downwards at a shallow angle of 20 degrees and only rises upwards again at a specific distance on four strips (radiation beams) in the direction of the stars.

Title: Roulette-like display device for a gambling machine
Inventor: THOMAS DIETMAR DIPL ING
IPC: G07F17/34
Filed: 1988-04-19
Abstract: The roulette-like display device for a gambling machine is composed of a roulette disc 3, on the edge 5 of which there are mounted in a conventional fashion winning spaces 6, to which there are assigned in a concentric sequence locking positions for a display means, and of a rotating display means. In order to be able to simulate the sequences of movement of a traditional roulette wheel as closely as possible using the display device, the turntable 3 is designed to be rotatable about its axis 4 and has its own drive taking the form of a stepping motor 9; a rotary body 13 is provided to enable the display means to rotate, is arranged behind the roulette disc 3 in the line of sight and coaxially with the latter and also has a stepping motor 14; and the two stepping motors 9, 14 run in opposite directions. In a further development, stepping motors 9, 14 with different numbers of steps are provided, especially motors with relatively large "lowest common multiples", preferably >/= 600. The rotary body 13 can, in particular, overlap the edge 5 of the roulette disc 3 and have a driver 23 which is directed towards the centre of the latter and supports a ball 22 at its end. <IMAGE>

Title: Motor vehicle seat with seat element and folding-over backrest element
Inventor: KLEEFELDT FRANK
IPC: B60N2/34
Filed: 1988-04-22
Abstract: Motor vehicle seat with seat element, back rest element which can fold over with respect to the seat element, bolt joint between seat element and back rest element and at least one back rest lock. The back rest lock has a rotating catch, an associated, fixed actuation bolt for the rotating catch and a swivelable ratchet. The ratchet rests in the upright desired position of the back rest with an engagement face on a counterengagement face of the rotating latch. In this way, the back rest is blocked against folding over. The ratchet can be disengaged in order to fold over the back rest. The ratchet has an auxiliary engagement face whose auxiliary engagement effect is opposed to the engagement effect of the first engagement face. The rotating latch has an auxiliary counter engagement face which blocks further movement of the back rest element when it passes beyond the desired direction. <IMAGE>

Patent DE-3817864-A1 (DE)
Title: Method for the transmission of an audio signal
Inventor: DICKOPP GERHARD PROF DR
IPC: H04B1/66
Filed: 1988-05-26
Abstract: For the transmission of an audio signal, the latter is divided up by means of a time window into temporally successive blocks, the signal components contained in the blocks are converted by means of transformation into a short-term spectrum, the short-term spectra are subsequently coded on the basis of psycho-acoustic legitimacy and transmitted, decoded after the transmission, the short-term spectra transferred back into the time domain by means of reverse transformation and finally joined to the blocks existing in the time domain. In this case, the blocks are divided into subsidiary blocks and, by means of changes in the level from one block to another, which overshoot a predetermined value, the signals in the subsidiary blocks are subjected before the transformation to a compression and after the reverse transformation to an expansion. To improve the noise separation, the signal in the subsidiary blocks is amplified and or attenuated during compression in the latter as a function of the average signal power in the subsidiary blocks and, during expansion, handled in a complementary fashion. In spite of a reduced data rate, the method enables a high-quality transmission of audio signals.

Title: Circuit arrangement for supplying a reluctance motor
Inventor: BROECK HEINZ VAN DER DR
IPC: H02P25/092
Filed: 1988-06-04
Abstract: A circuit arrangement for supplying a reluctance motor is described, comprising a D.C. voltage source having an asymmetric H-circuit for each winding (12, 13, 14) of the motor. In it, a first series arm (1, 5) is common to all the H-circuits and, in addition, each H-circuit has a second series arm (2, 6 or 3, 7 or 4, 8 respectively). Both series arms are arranged between terminals (9, 10) of the D.C. voltage source and each contain a switching element (1 or 2 or 3 or 4, respectively) and, arranged in series therewith, polarised in the reverse direction with respect to the D.C. voltage source, a rectifier element (5 or 6 or 7 or 8, respectively). The switching element (1 or 2 or 3 or 4, respectively) of the one series arm and the rectifier element (5 or 6 or 7 or 8, respectively) of the other series arm are, in this case, connected on one side with one and the same terminal (9 or 10, respectively) of the D.C. voltage source and the corresponding winding (12 or 13 or 14, respectively) is arranged in the cross-branch of the H-circuit, between the connections of the switching element (1 or 2, 3, 4, respectively) and of the rectifier element (5 or 6, 7, 8, respectively) of each series arm. This arrangement is constructed very simply and economically and allows optimal regulation of the reluctance motor. <IMAGE>

Patent DE-3909948-A1 (DE)
Inventor: BEGUN RALPH MURRAY
IPC: G06F9/44
Filed: 1989-03-25
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.

Inventor: NAKAMURA TAKESHI
IPC: B06B3/00
Filed: 1989-08-10
Abstract: The vibrator includes, for example, a triangular prism shaped vibrating body 14. On each of three side faces of the vibrating body, piezoelectric elements 16a1, 16a2 are formed respectively. The vibrating body makes bending vibration by giving a driving signal to one or two of the piezoelectric elements. The vibrator is used in a vibratory gyroscope. In this case, for example, only one piezoelectric element is used for vibrating the vibrator. When a rotating force is applied to the vibratory gyroscope, a Coriolis force is exerted to produce output voltages on the remaining two piezoelectric elements corresponding to the rotational angular velocity. The body 14 may be of Ni, Fe, Cr or Ti and electrodes of the elements 16a1, 16a3 can be of Au, Ag, Al, Ni or Cu/Ni alloy, deposited by sputtering or evaporation. Driving and receiving circuits are also disclosed. <IMAGE>
