Patent DE-3112048-A1 (DE)
Title: Method for controlling and regulating a synchronous machine which is supplied from a converter
Inventor: BECK HANS-PETER DIPL-ING
IPC: H02P25/034
Filed: 1981-03-24
Abstract: The control and regulation of a synchronous machine by means of thyristor invertors, the rotor rotation angle being measured, and a required rotation speed being compared with the actual rotation speed, is intended to be effected such that the tendency of the state variables to oscillate is overcome while the torque emitted by the machine corresponds with the required value. This is achieved in that the rotor angular displacement is effected as a function of the real current and reactive current, in that these values are additionally supplied to the drive unit (triggering equipment) for the thyristors, a power source supplying the invertor, with a capacitor connected in parallel with it whose nominal voltage value is adjusted over a characteristic as a function of the required rotation speed. <IMAGE>

Patent DE-3121034-A1 (DE)
Inventor: EILERS NORBERT
IPC: H04H20/00
Filed: 1981-05-27
Abstract: To improve reliability of recognition of an announcement recognition (AR) signal radiated by a transmitter upon broadcasting an announcement (e.g. traffic information, news, etc.) in the form of AM modulation of a 57 kHz auxiliary subcarrier, in which the subcarrier is essentially continuously modulated by region or radio-station recognition signals, the level of which changes when the announcement recognition signal is radiated, the subcarrier is filtered in the receiver, demodulated, and the degree of modulation by the frequency characteristics of the region or radio-station recognition frequency (RR) is sensed. If the modulation of the subcarrier at this frequency or frequency band (RR) drops from, for example, 60% modulation to 30% modulation, or less-a 50% level change-a switch (4) is activated which inhibits transmission of audio programs from an external source, such as a tape recorder (5), a tuner tuned to another station, or the like, and reproduces the program or announcement being broadcast by the station to which a region or radio-station recognition frequency is assigned. Termination of the AR signal (FIG. 3: t2), forming the AR modulation on the 57 kHz subcarrier, causes the switch (4) to revert for reproduction of previously controlled audio information upon increase in the level of the RR modulation on the subcarrier, which is sensed in a modulation sensing circuit or network (FIG. 2: 34-37).

Title: Walking harness for dogs
Inventor: SNIPPE WALTER
IPC: A01K23/00
Filed: 1981-07-01
Abstract: For years we have had in our cities the problem of the fouling of footways by dog excrement. A webbing harness, which is adjustable by means of buckles and primarily consists of two leg loops, is fitted to the rear part of the dog in accordance with its size. The loops are connected to each other on the animal's back, so that the support frame is tightly secured in contact with the dog's body. A closure ring is fixed on this support frame. The ring is so attached that its outer, upper middle is positioned directly below the root of the tail. Before going walkies, the open side of the waste bag is pulled through an insert ring, the open end is turned over the ring, and the bag with the insert ring is inserted into the closure ring by a short rotation. After the procedure, the insert ring and the bag are unscrewed. The bag is pulled off from the insert ring and thrown into the waste bin. The insert ring is placed in the pocket or screwed back into the closure ring. <IMAGE>

Title: Method for operating a PCM system and for operating a memory storing PCM signals
Inventor: BURGHARDT HARTMUT DR ING
IPC: H04M1/65
Filed: 1981-08-31
Abstract: In this method, the PCM signals correspond to a sequence of analog signals, a small proportion (S), for example 1% or 15%, of the PCM signal digits representing changed, that is to say impressed special digits (S) which in each case exhibit regular time intervals (ts) filled with a multiplicity of unchanged PCM signal digits, and form an impressed noise or an impressed interference with respect to the unchanged PCM signals. The special digits (S) represent additional stored digital information and are treated like digits of the PCM signals during transmission between connections or on retrieval of the PCM signals, that is to say they are not suppressed but also supplied to one or more connections or loads, for example a loudspeaker or a screen, as superimposed noise or as superimposed interference. The special digits (S) represent arbitrary information, which can be input by a user of the connection, that is to say not only markings which, when needed, are separately fed to a load by filtering out the unchanged PCM signal digits, independently of whether the PCM signals are also simultaneously fed to one of the connections or loads. The PCM signals can be words (bytes) consisting of bits which correspond to the difference of the respective analog signal from a reference value which is constant in time, the special digits (S) being impressed at least-significant positions (N) within the words (bytes). The PCM signals can also represent, for example, delta-modulated analog signals. <IMAGE>

Patent DE-3215247-A1 (DE)
Title: Pump for chemical (electroless) copper and nickel baths
IPC: F04D7/06
Filed: 1982-04-23
Abstract: The present pump is applied in electroplating principally for evacuating vessels which contain copper and nickel baths, irrespective of their dimensions. Because of undesired metal deposits from the liquid, the shaft driven by the motor is introduced into the pump housing with the interposition of an isolating gap which must, however, continually be filled with liquid in order to rule out access of air to the interior of the pump housing. The isolating gap is extended so far with respect to the vessel to be evacuated that its overflow is situated above the highest possible liquid level in the vessel. In the case of spacious vessels, it still operates perfectly as a submersible pump even if the liquid level drops away over the pump housing to the bottom. In the case of vessel dimensions that are too small, it is connected outside at the bottom drain of the vessel, and after being appropriately mounted it evacuates the vessel almost completely during the start-up.
