Title: Three=phase static inverter with symmetric output voltages - uses oscillator to produce three reference vectors for three single-phase inverters
Inventor: FORSTBAUER WILHELM DR
IPC: H02M1/084
Filed: 1980-08-01
Abstract: The 3-phase inverter contains three single-phase static inverters connected in parallel at their inputs to the dc source. The output of each inverter is connected via a low pass filter to a transformer. The output windings of the three transformers are connected in star configuration to give the 3-phase output. Each inverter is controlled by a controller comprising a vector-orientated control circuit and a control unit. A vector oscillator forms a 3-phase, balanced system of reference vectors for the vector-orientated control circuits. The 3-phase output remains balanced under all load conditions. Each control circuit shifts the independent pulse raster of its associated inverter until its output voltage vector has the same phase as the reference vector produced by the vector oscillator. The 3-phase output voltages are symmetric in angle since the oscillator produces symmetric reference vectors.

Patent DE-3110142-A1 (DE)
Title: Video recorder with improved audio signal recording
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: H04N9/835
Filed: 1981-03-16
Abstract: In a video recorder with helical track recording, the audio signal (AF) is also recorded in the helical tracks by modulating a subcarrier (1, 2) within the frequency spectrum of the modulated video carrier. In addition, an unmodulated subcarrier (3) is recorded. During the replay, this latter carrier supplies an interference signal (Us) due to the head switching. This interference signal is subtracted from the audio signal in subtracting stages (27, 28). This eliminates the interference signal in the audio which normally occurs due to the head switching. <IMAGE>

Patent DE-3128114-A1 (DE)
IPC: B67B3/24
Filed: 1981-07-16
Abstract: Mit meiner Erfindung will ich verhindern, daß gesetzte Infusions- und Injektionsstopfen wieder ausgestoßen werden und damit den Produktionsablauf erheblich stören können. Beim Stopfensetzen wird die über der Lösung im Flaschenhals befindliche Luft komprimiert. Hat der Stopfen nicht die genügende Haftung, wird dieser wieder ausgestoßen. Um das Komprimieren der Luft im Flaschenhals zu vermeiden, lasse ich eine geringe Menge Dampf (aus destilliertem Wasser) in den Flaschenhals einströmen. Der Stopfen wird gesetzt, der Dampf kondensiert und ergibt somit einen geringen Unterdruck, der den Stopfen nicht mehr freigibt. Auf diese Weise können auch Flaschen mit höheren Toleranzen im Durchmesser der Flaschenöffnung, Stopfen mit Abweichungen in der Härte und Silikonisierung oder auch schlüpfrige Lösungen ohne Schwierigkeiten produziert werden.

Patent DE-3132378-A1 (DE)
Inventor: GOECKLER HEINZ DIPL ING
IPC: H04J4/00
Filed: 1981-08-17
Abstract: A system for the digital conversion of a time division multiplex signal into a frequency division multiplex signal wherein the signals of the individual time multiplex channels are filtered by means of bandpass filters, their sampling rates are increased by the factor N to fA and the output signals of these bandpass filters are combined, by means of a summing member, into the frequency multiplex signal, and/or a system for the digital conversion of a frequency multiplex signal into a time division multiplex signal, wherein the digitalized frequency multiplex signal is divided by means of respective bandpass filters into the signals of the individual frequency multiplex channels and their sampling rate fA is reduced by the factor N. The individual bandpass filters (BP) are designed as recursive filters having the transfer function H(z)=U2(z)/U1(z)=P(z)/Q(zN) where U1(z) and U2(z) represent the filter input and filter output spectra respectively, z=ej2 pi f/fA, and f is the signal frequency.

Title: Steering-stabilisation means on pedal cycles
Inventor: GAHN KARL DIPL ING
IPC: B62K21/10
Filed: 1981-08-21
Abstract: The stabilisation of the straight-line self-steering capability of the pedal cycle is achieved by the particular position of the handlebar stem relative to the front wheel - known as positive castor or negative castor. Where the stabilisation effect is absent or deficient (for example because flexible material or creative considerations inter alia preclude a more pronounced fork slope), the rider is made to feel insecure and at risk. In order without making far-reaching changes to conventional designs to obtain in another manner aligning torques proportional to deflections, according to the invention there is arranged, between the rotatable handlebar stem and the fixed frame part (at least) one sprung rotary lever, one end of which is fixedly connected to the handlebar stem and the other end of which is supported against the rigid frame in such a manner that the necessary deflection movements are perfectly possible but torques occur which act from both directions to guide the steering back to the constraint-free central position. See sketch. By virtue of suitable selection of the spring properties of the spring body (rotary lever), the true positive/negative castor torques are simulated. The application brings advantages preferably in the construction of light-weight pedal-cycles where both security against the steering parts breaking and also satisfactory riding stability are sought. Retrofitting is also simple. <IMAGE>

Title: High-voltage power circuit breaker
Inventor: BARTH NOT-DURI DIPL ING
IPC: H01H33/915
Filed: 1981-10-12
Abstract: A high-voltage power circuit breaker has a moving (3) and a stationary (5) eroding contact. The moving eroding contact (3) is constructed as a nozzle having a nozzle constriction (7) and is rigidly connected to an insulating material nozzle (9) and to the compression piston (11) of a device for producing a compressed extinguishing gas. In the switched-on position, the stationary eroding contact (5) passes through the insulating material nozzle (9) in its constriction (10) and engages into the interior of the first eroding contact (3). The compression space of the compression device is connected to a volume (13) which, during switching off, contains compressed extinguishing gas before the separation of the two eroding contacts (3, 5). In such a circuit breaker, it is now intended to increase the switching off performance, using simple means, by means of intensive blowing and improved gas interchange between the switching-off arc and the surrounding extinguishing gas. This is achieved in that the diameter of the second eroding contact (5) and the diameter of the nozzle constriction (10) of the insulating material nozzle (9) are dimensioned in such a manner that an annular surface (F2), which is bounded during switching off after separation of the contacts by the nozzle constriction (10) of the insulating material nozzle (9) and the second eroding contact (5), is at least 30% of the size of the passage area (F1) of the nozzle constriction (7) of the first eroding contact (3). As a result of these measures, the switching-off arc (14) is blown twice as much at the start of contact separation, and the switching-off performance is hence increased. <IMAGE>
