Title: Gas-blast circuit breaker
Inventor: DOESSEGGER HUGO
IPC: H01H33/915
Filed: 1985-10-02
Abstract: A stationary arc contact element (12) has allocated to it an axial moving arc contact element (16) which is surrounded by a blow-out nozzle (24) which moves with it. On the inlet side, the blow-out nozzle (24) is connected to a gas space (21) which can be subjected to pressure during a switching-off stroke. Seen in the flow direction, the blow-out nozzle (24) has a narrowest point (27) which is arranged downstream of the free end (29) of the moving contact element (16) and is located upstream of an inwardly open annular groove (26). In order to offer an improved expansion capability for the switching gases which occur during a switching-off stroke and are severely heated by the switching arc, and, in addition, to enable the switching gases to mix more quickly with fresh gas, the annular groove (26) is arranged between the free end (29) of the moving contact element (16) and the narrowest point (27) of the blow-out nozzle. The profile of the base (30) of the annular groove (24) is rounded. The moving contact element (16) is tubular and, adjacent to its free end (29), has a diameter which expands like a diffuser. <IMAGE>

Title: Method and device for drying contaminated fluids and solutions
Inventor: BEST ALFRED DIPL ING
IPC: F26B3/347
Filed: 1985-12-14
Abstract: A method for drying contaminated fluids or solutions, to be precise especially weakly radioactive fluid compounds, using microwaves inside a closed vessel is specified, the walls of which vessel reflect the microwaves, and the resulting vapours being continuously drawn off. The method is carried out in the container which is intended for final storage, the microwave energy being supplied during the drying process with the microwaves being phase-shifted to match the respective filling level within the interior of the container and the changing absorption capability of the contents. The reflected power of the microwave energy is measured via a detector which is allocated to the microwave generator (magnetron), and a matching-transformation element inside the waveguide is regulated as a function of the measured magnitude in such a manner that the reflected power is controlled towards a minimum.

Title: Method for the analog or digital coding of information for use in angle- and pulse-modulation methods
Inventor: DIRR JOSEF DIPL ING
IPC: H04B3/38
Filed: 1986-03-29
Abstract: The important factor in the coding and transmission of analog or digital information is to transmit this information reliably and economically, that is to say with a narrow bandwidth. To improve the utilisation of the transmission paths, multi-valued coding and/or pulse-modulation methods have therefore been developed. The multi-valued coding methods could only be used reliably and with justifiable expenditure up to 16 QAM quadrature amplitude modulation or respectively up to 16 PSK phase modulation. In the invention, the reliability of transmission is increased and the expenditure reduced by changing the phase in the alternating coding current in such a manner that an uninterrupted sequence of positive and negative halfwaves is produced and/or the transmission is effected on the basis of angle or pulse modulation in a narrow band or only with an alternating code current of one frequency, the characteristic states being defined by the amplitude and/or phase steps.

The self-centring of the guide bushes (16) ensures that one roller (10') of the belt-grinding device is, in every position, tangential to the cylinder surface, so that a smooth surface without furrows can be ground. <IMAGE>
Patent DE-3641590-A1 (DE)
Title: Phase shift detector
Inventor: KUHN FRANK DIPL ING
IPC: H04B3/23
Filed: 1986-12-05
Abstract: In a phase shift detector previously proposed for detecting phase shifts in a sinusoidal tone, the latter, after coarse preselection in a first bandpass filter (2a) and conversion to a fixed frequency, is supplied to a highly selective second bandpass filter which shows a characteristic polarity reversal behaviour with incoming phase shifts in that the envelope of the output signal approaches the value zero. This arrangement must be simplified. A bandpass filter (7a) which can be tuned in the centre frequency of the pass band is introduced as second bandpass filter. For tuning, the first bandpass filter (2a) is followed by a frequency counter (4), the output signal of which is recoded to a tuning signal in a read-only memory (5). Use in a tone disabler in an echo canceller for detecting phase shifts in a sinusoidal tone of 2100 +/- 21 Hz. <IMAGE>

Title: Hydraulic brake system for a motor cycle
Inventor: GUTZEIT REINHARD DIPL ING
IPC: B60T8/34
Filed: 1987-04-09
Abstract: The proposed brake system is intended for a motor cycle and has a brake master cylinder (7) actuatable by pedal (6), a brake master cylinder (9) actuatable by hand lever (8) and an antilock device (10) and a rear wheel brake (3), a first front wheel brake (4) and a second front wheel brake (5). Through the antilock device (10), the brake master cylinder (7) actuatable by pedal (6) acts both on the rear wheel brake (3) and on the first front wheel brake (4). The antilock device (10) is at the same time designed so that risks of locking caused by the rear wheel brake (3) and the first front wheel brake (4) can be prevented independently of one another. The antilock device (10) is furthermore arranged so that brake pressures applied to the second rear wheel brake (5) by means of the hand lever (8) by way of the brake master cylinder (9) can be reduced in order to overcome the risk of locking. As a result, a motor cycle equipped with this brake system (2) can be safely controlled, irrespective of whether, for example, the pedal (6) and the hand lever (8) are simultaneously operated with too much force. <IMAGE>

Patent DE-3717809-A1 (DE)
Title: Simple pressure relief valve for flotation bags
Inventor: HILL STEFAN
IPC: B66F3/35
Filed: 1987-05-26
Abstract: Flotation bags, which, as is well known, are made of thin and flexible material, can only withstand a slight excess pressure. Therefore, the pressure regulating valve would have to be employed anew for every metre of depth in underwater operations. But if during manufacture, while welding together, a small piece of the weld seam is left open and covered on all sides with a larger piece of material (cloth), the external medium (water) will press on this cloth, thus closing the hole regardless of the depth under water (external pressure) at which this is done. At the slightest excess over the specified gauge pressure, the valve will open. After pressure equalisation, the piece of cloth will be pressed against the flotation bag again, thus sealing the hole again.   When ascending to higher layers of water, with a rapid fall in external pressure, the same thing will happen.
