Patent DE-3335172-A1 (DE)
Title: Circuit arrangement for initiating a switching or indicating process
Inventor: SCHUMM ERWIN
IPC: H02H3/30
Filed: 1983-09-28
Abstract: In a circuit arrangement for initiating a switching or indicating process, which consists of two physically separate points, preferably circuit parts which are allocated to the section ends of a high-voltage line, square-wave pulses which have a fixed phase relationship to the line current of the first point and needle-shaped sampling pulses, which have a fixed phase relationship to the line current of the second point, are formed and compared with one another. The adjustable edge separation of the individual square-wave pulse from the central position of the associated sampling pulse is used as a measure for the reliably judged maximum deviation. The deviation of the pulse coincidence of the square-wave and sampling pulses is used as the criterion for initiating switching or indicating. Critical phase differences which characterise fault cases can be detected at the latest after half a line current cycle by forming more than one square-wave pulse and more than one sampling pulse per cycle of the line current.

Title: Ball bearing mounted lightweight linear slide
Inventor: TERAMACHI HIROSHI
IPC: F16C29/06
Filed: 1983-10-25
Abstract: The fast acting reciprocating slide suitable for carrying a measuring instrument has a plastics or aluminium rectangular block forming a cage for two sets of recirculating balls.  The two sets travel along the sloping surfaces of a rail forming a track projecting upwards from e.g. a machine bed.  The balls circulate around two tracks, each in a plane at an angle to the horizontal to match the slope of the surfaces of the rail. The upper block has a central space underneath, into which the top of the rail projects and projecting end side of the space is an extension also sloping to match the slope of the rail surfaces, and holding a tapered block with grooves along two opposite surfaces, forming the track for the circulating balls. The corresponding sloping surfaces of the rail and spaces inside the block also incorporate grooves to complete the tracks.  End plates are attached to the block.

Title: Device for stabilising an external load
Inventor: REGNAT KARL
IPC: B64D1/04
Filed: 1983-10-26
Abstract: In the case of a device for stabilising an external load, which is suspended from an aircraft, with the aid of pivoting arms, on which spring-loaded pressure wedges act, in order to cause a large-area direct pressure wedge contact on the one hand on the pivoting arm and on the other hand on a supporting surface fixed to the housing, in every feed position of the pressure wedges, each pressure wedge is oriented with respect to the pivoting axis of the associated pivoting arm in such a manner that its one pressure wedge surface and the corresponding mating surface run inclined obliquely with respect to the pivoting axis at the wedge angle of the pressure wedge, while, in the region of its other wedge edge, it is guided in a longitudinally moving manner on a displacement axis parallel to the pivoting axis, and is supported such that it can rotate about said displacement axis. During external-load stabilisation, the pressure wedges and the pivoting arms operate independently of one another, but a switching mechanism which is of simple construction and is easy to operate allows the pressure wedges to be reset jointly against the spring force and hence allows the pivoting arms to pivot upwards so that they do not hinder the attachment of the external load. <IMAGE>

Title: Double-shell wall
Inventor: FERNAU ULRICH DIPL ING
IPC: G01N3/12
Filed: 1983-11-23
Abstract: The invention relates to a double-shell wall, preferably for vessels subjected to temperature and pressure loading, such as oil and gas tanks, as well as containments for nuclear power installations. The aim of the invention is to design the wall of a double-shell vessel wall in such a way that a concentration of bending, normal and constraining stresses in certain regions is excluded. According to the invention, this is achieved by the double-shell wall, formed by shells frictionally connected to each other, having in the central region of the temperature-loaded inner shell horizontal expansion compensators, running annularly around the shell, and vertical expansion compensators being arranged at the transition of the cylindrical wall to the base plate or to the vessel roof. The horizontal expansion compensators are preferably arranged in the joining region of the vessels made from annular segments. The length of the vertical expansion compensators corresponds at most to the distance between neighbouring horizontal expansion compensators. The expansion compensators are arranged in a chamber-forming manner, gas-tightly enclosing the seam of the inner shell.

Patent DE-3411697-A1 (DE)
Inventor: AHNE HELLMUT DIPL CHEM DR
IPC: G03F7/26
Filed: 1984-03-29
Abstract: Highly heat resistant polyimide and polyisoindoloquinazoline dione relief structures can be produced by applying radiation-sensitive soluble polymer precursors in the form of a film or foil on a substrate, irradiating the film or foil through negative patterns with actinic light or electrons or a light, electron, ion or laser beam, removing the unirradiated film or foil portions and optionally by subsequent annealing. The relief structures are produced in an inexpensive manner with high purity and in a chloride-free form as well as having economically acceptable exposure times as a result of using as polymer precursors poly-condensation products which are prepared in the presence of carbodiimides. The polycondensation products are prepared from diamino compounds or diamino compounds having at least one orthopositioned amido group and olefinically unsaturated tetracarboxylic acid diesters of aromatic and/or heterocyclic tetracarboxylic acid dianhydrides and olefinically unsaturated alcohols. The relief structures produced by the method according to the invention are suitable in particular for use as resist, surface protection, and because of the high purity as durable protective and insulating material in the semiconductor field.

Patent DE-3419031-A1 (DE)
Title: Automatic coupling for model railway vehicles
IPC: A63H19/18
Filed: 1984-05-22
Abstract: The invention relates to an automatic coupling for model railway vehicles. In model vehicles of relatively large track gauges, virtually all structural details of the full-scale originals are visible, including the coupling. The couplings hitherto used in such model railways are designed, in appearance and function, in accordance with the full-scale originals. Since such couplings can only be released manually, and this furthermore requires considerable dexterity, such couplings are unsuitable for a realistically proceeding operation of the model railway. To solve this problem, an automatic coupling is proposed which consists of a hook and coupling shackle and in which a hanging part (13) is arranged fixedly on the hook (14) and protrudes vertically from the coupling (11), and which furthermore has at its free end (15) a shackle part (17) which can be pivoted in the hook direction (16) and has a lever attachment (18), at the free end (19) of which is rotatably arranged a lifting rod (20) for the pivoting actuation of the coupling shackle (12), in order to release a coupling connection. An automatic coupling designed in this manner is released when it is moved via an uncoupling piece formed in the track body. The hanging part (13) is realistically incorporated into the coupling (11). <IMAGE>

Title: Process for producing an orientation layer for a liquid-crystal display
Inventor: SCHEFFER TERRY DR
IPC: G02F1/1337
Filed: 1984-08-24
Abstract: In the production of orientation layers for the liquid-crystal molecules of a liquid-crystal display, a covering layer (2) is bombarded obliquely by a jet of particles which contains macroscopic particles (5), in particular glass beads of a diameter less than 100 mu m. The striking particles (5) have the effect of producing on the surface of the covering layer (2) bead-like deformations, which cause a tilting forward of adjacent liquid-crystal molecules at a comparatively high angle. The process allows the use of organic polymer covering layers with good insulating properties and permits the simple texturing of large areas. <IMAGE>
