Patent DE-3812164-A1 (DE)
Title: Satellite antenna support
Inventor: MARGREITER HANS
IPC: H01Q1/12
Filed: 1988-04-12
Abstract: Satellite antenna supports require one or more rotation shafts for alignment with a geostationary satellite. Since the alignment must be carried out with very high accuracy, the rotation shafts must be constructed as precision parts which are intended to have little play, to be maintenance-free and to be resistant to corrosion. The actuating elements for pivoting the satellite antenna are also suspended in an articulated manner. In order to create considerable simplification from the design point of view, which simplification also feeds down in terms of costs, it is provided that at least one pivoting shaft (15, 33, 51) and/or the actuating shaft (16) is constructed as a bending or torsion element (21), which is free of rotation shafts, in order to support an actuating element. The satellite antenna support is used for satellite antennas. <IMAGE>

Patent DE-3815122-A1 (DE)
Title: Internal combustion engine
Inventor: CEBULJ KARL
IPC: F01C1/46
Filed: 1988-05-04
Abstract: In order to improve the torque and efficiency of an internal combustion engine with pistons rotating in an annular chamber and fixed on a central disc, it is proposed that the pistons be designed exclusively as working and exhaust pistons and that the annular chamber have fresh gas ports, which are connected to separate compressors. This design with preferably a few working pistons results in a high torque and a low engine speed level. Advantageous valve and shut-off valve actuations are also proposed.
Patent DE-3816136-A1 (DE)
Title: Power unit for reciprocating piston machines or engines
Inventor: GERNANDT HELMUT
IPC: F01B3/00
Filed: 1988-05-11
Abstract: A power unit for a cylinder-piston arrangement or two cylinder-piston arrangements 11, 12 horizontally opposed to one another, contains a flywheel 21 attached to the drive shaft 22, which flywheel on each of its two front faces has an eccentric ring groove 28, in which drive bushings engage for drive rods 36 running to cross head guides 52. Despite their eccentric arrangement the ring grooves 28 and the drive bushings surround the drive shaft 22, so that crank arrangements can be avoided and the bearings for the drive bushings 35 can be permanently grease-lubricated in the ring grooves 28. All other moving connections, too, especially the connections of the drive rods 36 with the cross head guides 52 and the slideways of the cross head guides 52 can be permanently grease-lubricated. In addition, devices for air cooling inside the power unit housing 16 can be provided on the flywheel 21 and devices for liquid cooling on the guide rods 54 of the cross head guides 52. Where only one cylinder-piston arrangement 11 or 12 is driven, two cross head guides 52 are nevertheless provided with drive by way of drive rods 36 from both faces of the flywheel 21, that cross head guide not used for driving a cylinder-piston arrangement receiving a counterweight. <IMAGE>

Title: Shutter-retaining means
Inventor: GAUGG JOHANN
IPC: E05C17/50
Filed: 1988-06-08
Abstract: The shutter-retaining means has two two-armed levers; an arresting means (5) is fitted on one lever (4) and the other lever (8) has a grip surface (9). The two levers (4, 8) are mounted such that they can rotate about in each case one pin (2 and 3, respectively) in a basic body, and they are connected in an articulated manner to one another by a bolt (7) and a slot (6). By pressing down the grip surface (9), the arresting means (5) can thus be withdrawn counter to spring prestressing. The arm (4) which bears the arresting means (5) has a bend, with the result that there may be provided, on the basic body (1), a bevelled portion (15) which acts as a run-on surface for a shutter. <IMAGE>

Title: Redundancy arrangement for information transfer in a hierarchically organised bus network
Inventor: ROHBECK VOLKER DIPL ING
IPC: G06F11/00
Filed: 1988-09-01
Abstract: The object is to create a redundancy arrangement for information transfer in a hierarchically organised bus network, in which the hierarchical levels are connected to each other by linking stations, when the information connection between a higher-level and a lower-level bus has been broken following a fault. According to the invention, either the lower-level buss with fault clearing capability are additionally connected to each other via switches controlled by control computers, or further transmitting and receiving devices, which are connected to each other via linking memories controlled by control computers, are connected to each lower-level bus with fault clearing capability. When the information connection between a higher-level and a lower-level bus has been broken following a fault, information is transferred as a backup via another, intact lower-level bus. The redundancy arrangements according to the invention are particularly useful in automated systems with a large number of decentralised intelligent functional units, which are connected to each other via a hierarchically organised bus network.

In this case, one of the bearing parts consists of an elastomer material and the other bearing part of a solid, preferably metallic material. Assembly is carried out simply by plugging them together until, in the contact position, the respective projections and grooves engage in one another.

Title: Process for mutually joining lattice threads
Inventor: KIRZINGER HORST
IPC: D04H3/14
Filed: 1988-10-21
Abstract: The invention concerns a process for mutually joining lattice threads for reinforcing webs, nonwovens or the like. Such a process is to be further developed to the effect that fabrication times, material and energy are saved and the environment is preserved. This is done by applying only to the warp threads and/or very thin threads additional to the warp threads an adhesive, for example a hot melt adhesive or the like, before the lattice is formed and, after formation of the laid, woven or knitted fabric, passing the particular type of lattice through a heating zone in which the hot melt adhesive or the like is thermally activated and the laid, woven or knitted lattice is directly fed to a supply reel. <IMAGE>

Inventor: SCHMEGNER KARL-ERNST DR ING
IPC: H01P1/26
Filed: 1989-03-15
Abstract: The invention relates to a waveguide termination which is partially filled with absorber material. In this case, that surface of the absorber material which touches the inner wall of the waveguide only at its edge and is exposed first is bounded in the waveguide by three contour lines whose outline is such that the first contour line at the free waveguide end connects two mutually opposite points located on the inner wall of the waveguide to one another transversely through the interior of the waveguide, and in such a manner that the two other contour lines each connect one of these two points to a common third point, which is likewise located on the inner wall of the waveguide, at the opposite end of the waveguide and at the same time each run on the inner wall of the waveguide. The position of the points is selected such that that part of the waveguide interior which is entirely or partially filled with absorber material tapers continuously from the free waveguide end in the direction of the opposite end of the waveguide.

Title: Rotor for open=end spinning - has weft formation groove reduced for fine counts
Inventor: STAHLECKER FRITZ
IPC: D01H4/10
Filed: 1989-09-08
Abstract: Open-end spinning rotor, turned on a lathe, has the groove radius reduced by a cold forging process. The process is also claimed. Pref. the interior of the rotor (1) is conical, and at the bottom of the wall (2) is cut a circular groove (4) which accepts the fibres to be spun into a yarn. The groove has a radius (R) which requires to be only 0.1 mm. Initially the rotor is turned in the usual manner, and then an exterior radius (14) is created, so that the wall (15) is reduced in thickness. The radius is equivalent to the interior radius (4). Flat surfaces (8,9') are also created, and this rim is then tooled (10',11) up, above and below, with the bottom tool (10') at a slight angle, with compression applied to reduce the height (H) to a predetermined tolerance. In this manner the surfaces (8,9') extend outwards, and the wall (15) compacts, reducing the radius of the groove (4). ADVANTAGE - The smaller groove is suitable for yarn of finer counts. Turning tools are not accurate and fine enough to produce the groove required.
