Patent DE-3322593-A1 (DE)
Title: Semiconductor arrangement and method of producing it
Inventor: BRUENIG PETER DIPL ING
IPC: H01L25/07
Filed: 1983-06-23
Abstract: The semiconductor arrangement comprises two disc thyristors Th1 and Th2 which are mounted in a gastight housing assembled in sandwich fashion and are connected in antiparallel. The housing is formed by two current rails 1 and 2 which form the outer boundaries and by a block situated between the latter and preferably made of three insulating plates 11, 12, 13. The thyristor discs 3, 4 are arranged in the recesses 23, 24 of the insulating plates 11, 12, 13 so that the anode side 15 of one thyristor disc 3 rests against the current rail 1, while the anode side 16 of the second thyristor disc 4 rests against the opposite current rail 2. The cathode sides 17, 18 are each then connected to the other current rail 2, 1 with the insertion of ductile copper discs 9, 10. Contact is made to each gate by means of contact points 5, 6 from which the gate connections 21, 22 are brought out through bores 19, 20 in the current rails 2, 1. The entire arrangement is sealed in a gastight manner by encapsulation in an elastic polymer (Fig. 2). <IMAGE>
Patent DE-3331901-A1 (DE)
Title: Reinforcing insert for flexible trimming or sealing strips
Inventor: FISCHER ROLF
IPC: B60J10/33
Filed: 1983-09-03
Abstract: Clamp-on profiles for motor-vehicle windows and similar applications contain a sheet-metal insert strip bent in the form of a U which is embedded in an elastomeric sheath and, to increase its flexibility and facilitate the installation of the profiles, is provided over its entire length with transverse slots in various patterns of arrangement. According to the invention, the sensitivity to tension of the insert strips due to this is counteracted by weaving or sewing in continuous textile filaments extending in the longitudinal direction. This makes it possible to use the extrusion process - which is economical - for encasing the sheet-metal strips.

Title: Novel headbox in papermachines
Inventor: BORN HORST ING GRAD
IPC: D21F1/02
Filed: 1983-09-08
Abstract: The novel headbox, invented by me, in papermachines is characterised in particular in that the pulp passes uniformly and without bubbles onto the wire. It has no exit lips and does not operate under pressure. The pulp passes through an orifice at the bottom of the headbox, over a bench with a rounding at its end and onto the wire. The thickness of the paper is regulated and controlled by vacuum. The higher the vacuum, the less pulp runs out and the thinner will the paper be. On the attached sectional drawing, the terms such as orifice, bench and rounding are indicated by reference lines.

Patent DE-3336721-A1 (DE)
Title: Photoelectronic sensing device
Inventor: BRUNNER GERHARD DIPL ING
IPC: B65H23/032
Filed: 1983-10-08
Abstract: In a photoelectronic sensing device for the peripheral region of a moving web, in particular for a web guidance device, having first and second housings, either a light source section and receiver section are situated in the first housing behind a window and a reflection surface or absorption surface is situated in the second housing or a broad-band light source section is situated in the first housing and a broad-band receiver section in the second housing. In known sensing devices, the housings are of expensive design. Parts of the light source section and receiver section, or of the light source section alone, which have to be maintained and replaced relatively frequently, are accessible only after an expensive dismantling of the housing or removal of the sensing device. According to the invention this is avoided by attaching the two housings so as to overhang a carrier plate at the free end of open tube profiles and by providing a detachable radial clamping element at least in the interior of the first housing for the purpose of axially securing in position and sealing. The detachable radial clamping element can be used to secure either a part of the first housing on the light source section and receiver section or the broad-band light source section in the first housing axially in position.

Patent DE-3346939-A1 (DE)
Title: Apparatus for spacing and sorting rolled bars
Inventor: HNIZDO HANS
IPC: B21D43/00
Filed: 1983-12-24
Abstract: The object is to provide a device of this kind which spaces and/or sorts the rolled bars comprising steel bars and sectional steel, which are to be fed in layers on transfer tracks to different machines or apparatuses present in finishing bays, in such a way that each rolled bar can be deposited with high accuracy and free from imposed bending stresses in one of the track lines which are distributed over the width of the transfer track and lead to the inlets of the following machines or apparatuses, it being possible to match the number and sequence of depositions on the track lines of a transfer track to requirements. This is achieved by arranging a spacing comb, the length of which corresponds to the width of the transfer track and which is mounted on a lifting frame of a carriage displaceable underneath the transfer track, in a manner which allows it to be displaced transversely, when the lifting frame is in a working position, out of an end position in the transfer track into an end position next to the transfer track (Fig. 1). <IMAGE>
Patent DE-3347460-A1 (DE)
Title: Process for the preparation of N-substituted carbamates
Inventor: BESENYEI GABOR
IPC: C07C271/06
Filed: 1983-12-29
Abstract: The invention relates to a process for the preparation of N-substituted carbamates from nitro compounds and hydroxy compounds as well as carbon oxide in the presence of water, bases as well as inorganic and/or organic selenium compounds with catalytically active selenium, in which process the catalytically active form of the selenium is prepared from selenium-containing compounds before or during the carbonylation reaction. The selenium compounds used as catalysts in this process are stable under normal conditions and can be converted into the catalytically active form by suitable activation. The use of the selenium compounds which have previously been employed as catalysts for the carbonylation reaction and which cause problems during handling can therefore be avoided according to the invention. It is not necessary for the reaction mixture to be completely free from water.

Title: Installation for heating the nozzle and the nozzle extension of a machine for casting metals
Inventor: MICENKO STEFAN DIPL ING
IPC: B22D17/20
Filed: 1984-12-06
Abstract: The invention relates to an installation for heating the nozzle and the nozzle extension of a machine for casting metals under pressure with a hot pressure chamber, in which a considerable part of the pressure chamber and of the riser are immersed in the melt in the crucible of the furnace, in which the riser is formed in the body of the hot pressure chamber, in which the pressure duct in the nozzle extension and the nozzle adjoin the riser, and in which the nozzle, the extension of the nozzle and the upper part of the riser are situated above the level of the melt in the crucible of the furnace. It is the object of the invention to provide a maintenance- and controller-free installation of simple construction for heating the nozzle and the nozzle extension, by means of which outstandingly good temperature equalisation is achieved without additional heat sources, without a controller and without operator intervention. The invention consists in the fact that a cavity surrounded by an outer surface is arranged around the nozzle extension to a point just ahead of the nozzle. The cavity, which is bounded by the outer surface, is connected to a system of ducts. The cavity and the ducts are filled with a heat transfer medium. It is advantageous to provide the outer surface with thermal insulation around it and to connect the cavity to atmosphere via the expansion vessel.
Patent DE-3445260-A1 (DE)
Title: Main cylinder
Inventor: VOLZ PETER
IPC: B60T11/236
Filed: 1984-12-12
Abstract: The main cylinder (1) is used in particular for hydraulic actuating devices in motor vehicles. It has a piston (4) formed in a cylinder housing (2) in a cylinder bore (3). The piston (4) is provided with an annular groove (5) in which a cross-sectionally U-shaped primary sealing-ring sleeve (6) is guided. The primary sealing-ring sleeve (6) has a radially inner sealing lip (17) bearing against the annular groove (5) and a radially outer sealing lip (18) sliding in the cylinder bore (3). The main cylinder (1) has a follow-up connection (16, 12, 10 and 23) which, during a pressure gradient from the follow-up chamber (12) to the pressure chamber (29), permits an afterflow of pressure fluid past the radially outer sealing lip (18) into the pressure space (29), in the course of which the outer sealing lip (18) is moved radially inwards by the pressure fluid. The side face (8) of the annular groove (5) on the pressure-space side is formed by a spring plate (31) which is supported against the piston (4) and whose surface section opposite the outer sealing lip (18) is part of a generated surface (34) of a cone which tapers in the direction of the pressure space (29). Wedging or adhering of the outer sealing lip (18) to the generated surface (34) is thereby prevented during the aftersuction action so that leakages cannot occur at the main cylinder (1), in particular during increased temperatures. <IMAGE>
