Title: Sealing system for a leakproof stern-tube seal
Inventor: PIETSCH GUENTER
IPC: B63H23/32
Filed: 1982-04-10
Abstract: A stern tube (13) for ships has a rear seal (1) and a front seal (2). The leakproof, environmentally beneficial rear seal (1) contains at least one annular chamber (4) in which a medium for lubricating the sealing elements is located. To increase the service life of the sealing elements and the leakproofness of the seal, the medium is pumped in a closed circulation system from a tank (3) through the annular chamber (4) and back to a separator (60) of the tank (3). The pressure PK in this circulation system is lower than the pressure PL in the stern tube and likewise lower than the minimum external water pressure PA min. Both sea water, penetrating from outside for instance, as well as lubricant penetrating from the stern tube (13) penetrating into an annular chamber (4) are carried away with the medium in the circulation system and are separated from the medium in the separator (60). An annular chamber (54) of the front seal (2) can be included in the circulation system. The seals and the lubricating medium can be monitored by means of the circulation system by means of monitoring devices at the tank. In the event of a fault in the circulation system, it is ensured that sufficient medium remains in the annular chambers (4, 54) in order to maintain lubrication of the sealing elements. <IMAGE>

Title: Transfer arrangement for transferring calls from a two-wire line to a two-way radiocommunication unit
Inventor: HOFBAUER JOSEF ING GRAD
IPC: H04B1/46
Filed: 1982-05-27
Abstract: Transfer arrangement for transferring calls from a two-wire line to a two-way radiocommunication unit and vice versa, where the two-way radiocommunication unit in its off position is switched to reception and the transmitter is keyed in speech-controlled fashion. In the transmission direction, the signals are fed from the two-wire line to a controllable amplifier (VRs) which is set in its off position to maximum amplification and which resets its amplification with a very short time delay tan1 from the maximum amplification to the respective peak speech level arriving from the two-wire line. The controllable amplifier (VRs) has a very long maximum amplification reset time tab1 which is in the order of magnitude of the mean speaking time of a radio subscriber. The controllable amplifier (VRs) emits a maximum output voltage (Umax) at the peak speech level to which it is currently set. The output signal of the controllable amplifier (VRs) is fed on the one hand via a first switch (S1) as AF modulation to the transmitter of the two-way radiocommunication unit (S/E), and on the other hand to a control device (Sprachstg.) which rises with a very short rise time tan2 from the voltage Umax minus a predefinable value and falls again with a fall time tab2 which corresponds to the mean length of speech pauses. The output signal of the control device (Sprachstg.) keys the transmitter (S) of the two-way radiocommunication unit (S/E) via a control logic (Logik) and closes the first switch (S1). <IMAGE>

Title: Protection device for asynchronous motors
Inventor: KOLMEDER WALTER DIPL ING
IPC: H02H7/08
Filed: 1982-08-03
Abstract: The invention relates to an electrical protection device for monitoring especially converter-supplied asynchronous motors. It is intended to create a protection device which reliably detects all the disturbance cases throughout the speed range which are required to disconnect the motor, irrespective of whether it is used with mains-supplied or converter-supplied machines, and, if such disturbances occur, causes the disconnection of the motor. This is achieved by means of a circuit which generates an electrical actual signal corresponding to the root-mean-square value of the respective phase current for each phase of the asynchronous motor, a first comparator circuit, in which the electrical actual signals are compared with a limiting value which can be preset, and a first disconnection signal is generated when at least one actual signal exceeds the limiting value, a second comparator circuit which compares the actual signals with one another and generates a second disconnection signal when the actual signals deviate from one another by more than a difference which can be preset, by means of a third comparator circuit which, in the frequency band of the phase current below a frequency limit which can be preset tests the actual voltage applied in each case to the motor for correspondence to the nominal voltage of the converter associated with the instantaneous frequency and generates a third disconnection signal if the actual voltage is less than the nominal voltage by a magnitude difference which can be preset, and by a device for disconnecting the motor when a disconnection signal occurs.

Title: High-voltage switching chamber
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/70
Filed: 1983-04-06
Abstract: For reliable interruption especially of very large short-circuit currents in the vicinity of a generator, and for a high dielectric strength of the interruption space in the switched-off condition, two axially opposite nozzle bodies (3, 4) consisting of electrically conductive material are arranged as follows: the one nozzle body (3) is electrically conductively connected to a tubular current track (5). An insulating sleeve (30) is located between the other nozzle body (4), which is integrated into a piston body (10), and the tubular body (11) supporting it. Thus no current flows through this nozzle-piston body. The switching-off arc is initiated on the inner wall of the nozzle body (3) by an arc switching piece (17) and is then dragged in. During its further existence in the nozzle space, the arc is surrounded by the erosion-resistant inner walls of the nozzle bodies (3, 4). In the switched-off state, the dielectric strength of the free gas path between the nozzle bodies (3, 4) is increased by the dielectric strength of the insulation between the nozzle-piston body (4, 10) and its supporting body (11). <IMAGE>

In order to avoid this drawback, the acid flowing out of the bottles 1 flows into the acid collection region 2 of a collection trough 3 and from there back into the acid reservoir 4, and rinsing commences when the particular bottle 1 has been displaced by continuous rotation of the rinsing table 5 to such an extent that the water outflow line 6 is located above the water collection region 7. <IMAGE>
Patent DE-3318788-A1 (DE)
Title: Record player
Inventor: SEEGER ERHARD
IPC: G11B33/08
Filed: 1983-05-24
Abstract: The record player (10) has in one basic version a two-part housing (14) which entirely accommodates the turntable (12) with its drive (13) and the pick-up arm (19). Each time the record player is put into operation to play a record, the housing is at least partially evacuated. Due to the reduced air density within the housing (14), the pick-up arm (19) is to a great extent shielded from the accoustic oscillations occurring from outside on the housing, emanating either from the loudspeakers, which are controlled by the record player itself, or possibly originating from another sound source. As a result, the pick-up arm (19) is protected against superposed oscillations, in particular sympathetic oscillations, which otherwise can cause at least distortions of the sound reproduction, if not even damage to the pick-up system and the record. In the case of the second basic version, there is a housing with a baseplate (45) and a two-part cover shroud (46; 47), which entirely accommodate the turntable (42) and the pick-up arm (43). The intermediate space (51; 61) of the two-part cover shroud (46; 47) is at least partially evacuated, so that, by virtue of the reduced air density within the cover shroud, the accoustic oscillations occurring on it from outside can reach the inner space only with a much attenuated effect. As a result, here too the pick-up arm (43) ... Original abstract incomplete. <IMAGE>
