Patent DE-3639643-A1 (DE)
Title: Interferometer direction-finding arrangement
Inventor: SCHOEFFEL PETER DIPL ING
IPC: G01S3/46
Filed: 1986-11-20
Abstract: An interferometer direction-finding arrangement is described having two physically separate antennas which are connected periodically and alternately to a common reception channel. The oscillation of a heterodyne oscillator is fed via a controllable phase modulator to a frequency converter in order to convert the received signal to an intermediate frequency. The phase modulator is switched between two phases in synchronism with the antenna switching, the phase shift between which phases can be adjusted by means of a control voltage. Phase demodulation determines the phase modulation of the intermediate-frequency received signal and a regulator uses the output signal of the phase demodulator to derive a regulation voltage for adjusting the phase shift of the phase modulator, in such a manner that the phase modulation of the intermediate-frequency received signal disappears. The phase shift setting of the phase modulator (and the associated regulating voltage) is then a measure of the incidence direction of the received wave.

Title: Circuit arrangement and method for a gate-turn-off power semiconductor
Inventor: AMELUNXEN BERND DIPL ING
IPC: H02M7/515
Filed: 1987-11-07
Abstract: Gate turn-off power semiconductors (3, 4) such as GTO thyristors, are frequently connected in parallel with the series circuit of a diode (8, 9) and of a first capacitor (7, 10) as turn-off limiting network, the diode (8, 9) being connected in parallel with a discharge resistor (11, 12). To use the energy released during the discharging of the first capacitor (7, 10) at least partially usefully for the inverter operation, it is proposed to arrange in parallel with the first capacitor (7, 10) a series circuit of a controllable valve (14, 17), an inductance (15, 18, 25) and a second capacitor (16, 19), the second capacitor (16, 19) exhibiting much greater capacitance than the first capacitor (7, 10). When the first capacitor (7, 10) is charged, a discharge current (I17) from the first capacitor (7, 10) via the controllable valve (14, 17) to the second capacitor (16, 19) is turned on, the controllable valve (14, 17) being turned on at the same time as the power semiconductor (3, 4). <IMAGE>
Patent DE-3739579-A1 (DE)
Inventor: VANEK ZBYNEK
IPC: B31B50/62
Filed: 1987-11-23
Abstract: The arrangement comprises a rotatable drum (1, Fig 1) with sleeves (3) comprising rocking walls (15, Fig 2), each of which sleeve is adapted to receive up to three boxes. The sleeves are heated either each individually or by a common heating body. All three boxes are ejected simultaneously by an ejector (9, Fig 2) which in case of a contact with the boxes always starts from a zero speed. To achieve this, the ejector (9) comprises a bushing (8), a shank (7), a compression spring (10) and a clamp (11) connected with a spring loaded pin (12) engaging into grooves of a grooved disc (13 & Fig 3), the depth of the grooves corresponding to the number inserted into the sleeve. The figure shows a third box being loaded against the ejector with a further representation on the right of the grooved disc. <IMAGE>
Patent DE-3740748-A1 (DE)
Title: Time control and time-control device for laundry driers
Inventor: OTT GUENTER ING GRAD
IPC: D06F34/06
Filed: 1987-12-02
Abstract: A known drying-process time control counts the cooling times or heating cut-out times by means of an electrical clock. In this case, however, factors leading to different drying results are not taken into account. The new time control is driven solely by the heating cut-in times and provides reproducible drying results. After the drying time has been set, a bipolar cut-in switch (1) of an electromechanical time switch driven by a synchronous motor (2) is closed, and voltages applied to the heating (4) as well as to the synchronous motor (2) connected in parallel thereto. The contact (3') of the thermostat (3) is in series with the parallel connection (4), (2) and, after its switch point has been reached, cuts out the heating (4) together with the synchronous motor (2), so that the set drying time cannot run any further. The drying time continues to run only after the heating (4) has been cut in again by the contact (3').   The new time control and time-control device are suitable for laundry driers, combination washer driers and drying appliances of a general kind. <IMAGE>

Title: Wheel, with pneumatic tyre, with width adjustment
Inventor: HOMEYER ULRICH VON DIPL ING
IPC: B60B21/02
Filed: 1988-01-14
Abstract: In order to avoid, and to improve, the compromises relating to the tyre contact face and profiles which are usually inadequate in practice, the wheel or rim is to be adjustable in width (base width) in order to ensure that, on the one hand on a hard firm underlying surface (e.g. road) with a narrow setting of the base width, consequently high internal pressure of the tyre and small contact face, mainly the central part of the tyre or profile performs the load-bearing function, on the other hand when travelling off the road (e.g. field) with a large setting of the base width, consequently low internal pressure of the tyre and large contact face, mainly the outer parts of the tyre or profile perform the load-bearing function and provide grip.

Title: Paper transporting roller and its use in a printing device
Inventor: ARMBRUSTER FRANK
IPC: B65H27/00
Filed: 1988-01-28
Abstract: Known paper transporting rollers have a plastic body with a cylindrical roller surface. To avoid slip between the paper transporting roller (1) and paper (12) to be transported by it, the paper transporting roller (1) bears a hard graining (6, 8) on its roller surface (5). Inside a thermal printing device, the paper transporting roller (1), when running directly against the heating elements (10) of a thermal print head (9), removes any foreign bodies, such as burnt-on ink, which may have accumulated there. <IMAGE>

Abstract: The container has an integral removal element (10) which has a bung (12), a liquid guiding body (14) and a film hinge (16) connecting these parts. The guiding body (14) can be pivoted from a position (14') parallel to the bung axis which it adopts when the removal element (10) is fixedly welded to a first web of film by advancing a second web of film into a position perpendicular to the bung axis.

Title: Method and device for programming receivers for picture and sound broadcast transmissions

Abstract: To program receivers for picture and sound broadcast transmissions, in which the operating functions set such as, for example, channel numbers, tuning parameters, picture and sound adjustment values, transmitter abbreviations and teletext page numbers can be stored as digital data in an internal memory, all operating functions for a desired receiving region are manually set at a first receiver (1) and loaded as digital data in the internal memory (2), the data stored for these settings are read out of the internal memory (2) again via connections brought to the outside and loaded into an external non-volatile memory (6, 7, 8), after which the data stored in the external memory (6, 7, 8) are loaded via connections brought to the outside into the internal memory (2a, 2b, 2c, ...) of each further receiver (1a, 1b, 1c ...) to be programed within the same receiving region. <IMAGE>

Title: Frequency-selective optical data recording and data reproduction apparatus
Inventor: NAKAJIMA HAJIME
IPC: G11B7/24
Filed: 1988-08-16
Abstract: The frequency-selective optical data recording and data reproduction apparatus emits a light beam which is directed at a recording medium and the wavelength of which sequentially assumes one of a plurality of possible values, and with variation of the wavelength writes or reads each information (data) bit multiply. Predetermined data are recorded in advance at a reference wavelength for writing and reading. The recorded data are read at the reference wavelength and these read data are stored in a memory. These data are compared with those data which are obtained by reading the recorded predetermined data at the wavelength at that instant of the light beam. On the basis of this comparison, the wavelength at that instant is set to the value of the reference wavelength and stabilised there. The apparatus performs the recording and reproducing operation by means of a semiconductor laser, which is operated in a longitudinal cavity mode caused by a change in the injection current, as a result of which the oscillation wavelength control, i.e. the controlling of the wavelength of the laser light, is simplified. The wavelength variation over time induced by the change in injection current is synchronised with the timed activation of the laser for generating a light beam. <IMAGE>
