Patent DE-3414814-A1 (DE)
Title: Gas turbine
Inventor: WEBER FRANZ-JOSEF
IPC: F02C7/12
Filed: 1984-04-19
Abstract: In order to prevent deviant flows of the working media caused by pressure differentials between the fuel gas and the fresh air in a gas turbine with housing divided into ducts for fuel gas and fresh air and alternating admission of the fuel gas and the fresh air to the turbine blades, which also act as heat exchangers, the gas turbine is designed in such a way that in each turbine stage an equal pressure obtains in both media ducts, which is achieved both by the distribution of the compressed fresh air coming from a double-flow radial compressor between the combustion chamber and the inlet of the fresh air duct, and also by the nozzle-shaped design of the guide vane ducts in the air duct, so that the turbine wheels additionally have rotation imparted to them also in the air duct by the compressed air. This low-pressure, small gas turbine with axial blading is intended for use as an engine for current generators, hot water washing appliances for vehicles, ships and light aircraft, where, with its blade-heat exchange, it results in cheaper production and fuel savings previously unattained.

Title: Arrangement for transmitting a pulse train for firing a thyristor
Inventor: GOLLER ALOIS DIPL ING
IPC: H03K17/00
Filed: 1984-06-22
Abstract: The pulse train is transmitted by means of a pulse transformer (1), the primary winding (1a) of which is connected via a periodically actuatable switch (4) to a power supply and the secondary winding (1b) of which is connected via a blocking diode (7) to the triggering electrode of the thyristor (8). In addition, a steep pulse, which is generated with the discharge of a capacitor (14) via the primary winding (1a), can be added on at the beginning of each pulse. To reduce the power loss, a current stabilising circuit (2), which is used for keeping the firing current constant, is provided in the primary circuit. This also allows the transformation ratio of the pulse transformer (1) to be increased. <IMAGE>

Title: Interference-suppressed arrangement comprising a converter circuit and a machine
Inventor: KOELLENSPERGER DIETER DIPL ING
IPC: H02K11/02
Filed: 1984-10-31
Abstract: When switches, in particular transistors and de-activation thyristors, are actuated in rectifier devices, jumps in potential occur on the feeder lines (RST) of a connected machine which may stimulate noise currents via parasitic capacitors (CM, CM') and noise-sensitive system components (control electronics, mains system N). These noise currents are fed via a connection (coupling capacitors CK, CK1, CK2), which is high-impedance for low-frequency processes and low-impedance for high-frequency processes only, past the noise-sensitive system components and are discharged into the intermediate circuit capacitor (ZK1, ZK2) of the converter circuit. Radio interference suppression of the mains system as well as interference suppression of the control electronics of a regulator or pulse converter can thereby be achieved. <IMAGE>

Patent DE-3445561-A1 (DE)
Title: Shaft sealing ring
Inventor: KERN HERMANN
IPC: F16J15/3256
Filed: 1984-12-14
Abstract: A shaft sealing ring has a first sealing part with an annular wearing body which is provided at least partially with a casing. It has at least one sealing lip, which rests in a sealing manner against a rotor ring of a second sealing part. In the out-of-operation position, the sealing parts are supported axially against one another with the interposition of at least one coupling part and, during operation, rotate relative to one another. In the operating position, one coupling part is connected rotationally to at least one of the two sealing parts. The coupling part which lies between the two sealing parts prevents contact between the two sealing parts during operation. It rotates with one of the two sealing parts and can exhibit a clearance with respect to the other sealing part. Friction between the sealing parts is thereby avoided and hence these do not wear, nor can they be damaged or, what is more, destroyed by excessive heating.

Title: Installation for machining rolling-contact bearing balls
Inventor: CERMAK VLADIMIR DIPL ING
IPC: B24B11/06
Filed: 1985-01-15
Abstract: The stripper strip according to the invention is intended to push machined balls continuously out of the grooves (3) between the end faces of machining wheels (1, 2) in a vertical machining installation. The strip is fitted in the outlet area of the upper wheel (1) and is configured in the form of a partial cylindrical or spherical casing, beneath the end of which a discharge strip (12) is fitted which leads down to the magazine (7) which is arranged about the two machining wheels (1, 2). Guiding grooves which are advantageously in the shape of a helix and run from the edge of the strip to the magazine (7) are made on the inner casing surface (13). The design of the stripper strip prevents undesirable damaging of the surface, in particular of high-precision balls. <IMAGE>

Title: Electrical multiple plug socket
IPC: H01R25/00
Filed: 1985-04-11
Abstract: The invention relates to an electrical multiple plug socket for optional insertion of an earth-contact plug or two Europa flat plugs into a common insertion recess. The unobstructed width of the insertion recess in this case corresponds to the circumferential diameters of the earth-contact plug and to the depth and width dimensions of the Europa flat plugs. The multiple plug socket according to the invention is characterised in that a retaining element, which can be displaced axially in the insertion direction, is inserted into the insertion recess. This retaining element consists of a base plate and of walls which are integrally connected thereto and project on one side against the insertion direction. The base plate and the walls form two retaining spaces corresponding to the external contours of the Europa flat plugs. These retaining spaces are separated from one another by a common centre wall. The regions of the base plate associated with the two retaining spaces in each case have the two plug openings for the contact pins of a Europa flat plug and, arranged centrally between them, in each case one plug opening for a contact pin of an earth contact plug.
Patent DE-3517498-A1 (DE)
Title: Centrifugal pump in a sheet-metal construction
Inventor: APFELBACHER ROLAND
IPC: F04D29/42
Filed: 1985-05-15
Abstract: The invention relates to a centrifugal pump in sheet-metal construction, which is provided with a pressure joint having a central outlet and a tangentially arranged inlet. Owing to the inlet and outlet cross-sections arranged at different planes there results an arc-shaped profile of the pressure joint. So as to be able to acccommodate the potential large pipeline forces, the outlet port and the connection flange joined thereto are connected to the pump casing by means of a supporting member or by struts. Thus a flexurally very rigid casing is produced which is able to accommodate the large pipeline forces acting on centrifugal pumps without any difficulty.

Title: Device for metering ink on printing machines
Inventor: JENTZSCH ARNDT DIPL ING
IPC: B41F31/00
Filed: 1985-08-10
Abstract: The invention relates to a device for metering ink on printing machines. The aim of the invention is to rule out uncontrollable falsifications of the setting of the ink knife. The object is achieved by removing the harmful effects of the ductor deflection as a result of the forces acting when the ink passes through the gap between the ink knife and the ductor. According to the invention, this is achieved in that a cutting roller is arranged closely adjacent to the leading edge of the ink knife, which cutting roller can be engaged with the ductor, receives the ink film from the ductor and transfers it to the vibrator. The cutting roller is driven in the same direction of rotation as the ductor. The drive of the cutting roller is derived from the inking unit via an intermediate gear. <IMAGE>

Patent DE-3539914-A1 (DE)
Title: Air-conditioning control installation for animal and plant containers
Inventor: FORSTER PETER
IPC: A01G9/24
Filed: 1985-11-11
Abstract: In a case in which plants and animals are kept in containers, climatic conditions which are as natural as possible must be provided. The control technology used to this end is restricted to installations which calculate only one or a few temporally staggered desired values. For this reason, the natural daytime and annual fluctuations cannot be simulated. The invention solves this problem by measuring the fluctuations in the external climate and, after electronic modulation to the respective desired climate type, calculating them as the desired value for the climate in the container.
