Title: Device for intrinsically safe DC supply
Inventor: TRETOW JOCHEN ING GRAD
IPC: H04M19/00
Filed: 1981-04-15
Abstract: For a device for intrinsically safe DC supply of a data or telephony transmission system operating with RF carriers, the object is to indicate a data transmission system operating with RF carriers in which the blocking attenuation is increased for the useful frequencies between the DC supply unit and the transmission unit and vice versa. This is achieved by inserting Wagner half-elements (4, 5) as blocking circuits for specific frequency ranges in series into the lines (2, 3) feeding the output of a DC supply unit (1), each inductor (L1, L2, L3, L4) of the longitudinal arm being bridged by diodes (V1, V7 etc.) connected back-to-back and a transient absorbing diode (V9 or V10 respectively) being inserted in each half-element in the shunt arm. A special application involves transmission systems in mining and other areas where there is a risk of explosion. <IMAGE>

Title: Holder (mount) for a plane mirror
Inventor: HANKE PETER ING GRAD
IPC: G02B7/182
Filed: 1981-05-14
Abstract: A description is given of a holder for a plane mirror, in which a support plate consisting of a metallic material is joined to the mirror at gluing points. The permanently elastic gluing points absorb the differences in expansion between the mirror and support plate over the entire operating temperature range, so that the mirror is not deformed by the thermal differences in expansion. In order to achieve a position of the mirror which is stable and largely insensitive to external influences, additional provision is made of self-closed elements which prevent a translatory movement or rotation of the mirror.

Title: Process and apparatus for consolidating the edge of sheet-like structures
Inventor: POLLACK DIETER DR ING
IPC: B29C65/16
Filed: 1981-08-17
Abstract: The invention relates to the needling-free edge consolidation and the simultaneous joining and/or separating of sheet-like textile structures. The aim is to achieve the rapid and continuous consolidation of the edge of all types of fabric and fibres at a high consolidating and separating speed. The object is, irrespective of the type of fibre and the thickness of the sheet-like structure, to produce a homogeneous highly consolidated edge and at the same time to join it or separate it. The essence of the invention is the combination of edge compaction and a complete impregnation and wetting of the fibres or threads at the edge or at the seam and/or separating point by means of mechanical vibrations, especially in the ultrasonic range, a subsequent or superposed consolidation of a liquid polymerisable wetting material by means of electromagnetic waves and a subsequent or simultaneous consolidation and separation by laser at the edge or seam point. The sector of use embraces articles with a consolidated edge or seam of any shape and dimension, for example carpets, articles of clothing, towels, babies' napkins or the like. <IMAGE>

Inventor: BROEKSMID ERICH
IPC: H02K15/04
Filed: 1981-11-14
Abstract: During the bending of flat copper conductors (11) for rotor windings of generators, the inner strands are compressed, with the result that material is forced out at the side.

Title: Ball joint connecting platform to sea-bed anchor
Filed: 1981-04-27
Abstract: A ball joint is for connecting a platform to a foundation anchored on the sea-bed. It has an upper, outer and lower, carrier port-spherical shells and has downwardly open air or gas-filled bell that encompasses the lower shell, and with an annular seal bearing against the lower shell.  Arranged in the lower shell are sliding shoes which have curved carrier plates having trapezuim-shaped peripheries, and side layers fixed to the carrier plates and sliding on the inner surface of the surrounding upper shell, the side layers being encompassed on all sides by edge stri portions of the carrier plates. The carrier plates are provided along all sides with edge seals mounted in ede recesses. These seals bear against the inner surface of the upper shell. The functioning of the ball joint over a long period, e.g. 30 years, is achieved by providing the shells with improved protection of the sliding surfaces, by achieving and maintaining floating frictions and bv forming the sliding shoes to facilitate replacement.

Title: Process for the production of ammonia synthesis gas
Inventor: MECKEL JOACHIM F
IPC: C01B3/02
Filed: 1982-02-24
Abstract: A process is described for the production of ammonia synthesis gas from a starting gas acting as a hydrogen carrier, which starting gas is reformed with steam to give a cracked gas containing carbon monoxide and hydrogen and is then converted to give a gas containing carbon dioxide and hydrogen, in which process the required hydrogen/nitrogen ratio is established by direct addition of a nitrogen carrier gas into the main gas stream, the cracked gas being subjected, after conversion, to purification from carbon dioxide and carbon monoxide, for example by carbon dioxide scrubbing and methanation. To simplify such a process, the invention proposes that the nitrogen carrier used is a lean gas.

Inlet orifices (5) and (6) for each plastic component enter the mixing chamber. As it flows, the mixture of plastic components is divided, by the cascade-like structure, into a plurality of part-streams and thereby subjected to additional mixing, and passes, with sufficiently laminar flow, into a mold.
Patent DE-3216833-A1 (DE)
Inventor: BRAJDER ANTONIO
IPC: H03K17/0812
Filed: 1982-05-05
Abstract: A protective circuit for a switching transistor is disclosed in which the base-emitter voltage of the switching transistor is compared in a comparator with a reference voltage. If the collector current of the switching transistor increases, the base-emitter voltage also increases, with the base current remaining constant. As soon as the base-emitter voltage exceeds the reference voltage, a signal is delivered at the output of the comparator. A switching-off device for switching off the driving pulses of the switching transistor responds to this signal so that a switching-on pulse present at the base of the switching transistor is switched off. The reference voltage is fixed so that the switching transistor is protected against overload by excessively large collector currents.

Title: Process for the high-level storage and removal of palletised goods in high-density stores
IPC: B65G1/04
Filed: 1982-06-04
Abstract: According to the process, three storage levels of the high-density store are connected together in each case in a vertical direction by an intermittently operating conveyor means or frame. The conveyor frame consists of two load reception planes arranged one above the other at the spacing of the storage levels and is intermittently moved alternately upwards and downwards. For storage, the palletised storage goods are conveyed from the central storage level alternately into the upper and lower level, the storage goods in the central storage level being simultaneously pushed onto the conveyor frame and in the upper or lower storage level pushed off. The distribution of the storage goods in the individual storage channels of a storage level is carried out via one storage section respectively.

Title: Method and device for stacking metal ingots etc., especially copper ingots
Inventor: SIMON ERFRIED
IPC: B65G57/081
Filed: 1982-11-27
Abstract: According to the invention, the actual rotational position of each ingot is detected on a conveyor line and, if this deviates from the rotational position required for stacking, the ingot is turned by a manipulator until it reaches the required position. Downstream of the manipulator, the ingots are suitably fed to a collector, which groups the ingots into individual stack layers which are then stacked vertically by means of a stacking device, to produce the finished stack. A rotary tube which can be rotated about its axis and has a simple cylinder drive is preferably used as a manipulator.
