Title: Supporting structure for non-loadbearing building parts, for example walls or piers and a reinforced-concrete structure, for example a building ceiling
Inventor: MASTIAUX WILHELM
IPC: E04B1/36
Filed: 1983-11-29
Abstract: In the case of a supporting structure for non-loadbearing building parts, for example walls or piers, and a reinforced-concrete structure, for example a building ceiling, with the aim of simplifying the installation of anchoring elements of a supporting structure assumed to be known and reducing the extent of skilled craftsmanship to be required for its erection and the necessary supervision as well as also of avoiding the previously existing possibilities of faults occurring in the anchoring elements, the invention provides a formwork element which is permanently in the reinforced-concrete structure and keeps open in the said structure a clearance which is adapted to the pin in length and outline and has a foot which has a level base for the formwork and clearances for the positive connection to the formwork, which closes the form space of the reinforced-concrete structure on the face facing towards the building part concerned, as well as that the anchoring element is introduced with its hole element, finished in a way known per se, or pin fitted into the inserts thereof, until the upper edge of the hole element makes contact with the foot sunk in the formwork structure, the flexible intermediate layer covering the foot.
Patent DE-3344533-A1 (DE)
Title: Tolerance-ring connection
Inventor: HANAGARTH WOLFGANG
IPC: F16D1/08
Filed: 1983-12-09
Abstract: The invention, which relates to a tolerance-ring connection between two parts, of which at least one is composed of a low-strength material, renders superfluous the metal sleeve hitherto necessary for such a part by the fact that the tolerance ring has larger surfaces of contact with the low-strength part than with the high-strength part, the total size of these contact surfaces being determined by the reciprocal quotients of the strength and elasticity characteristics of the materials concerned. This results in an enlargement of the surface of contact of the tolerance ring with the low-strength part and hence a reduction in the unit pressure. The tolerance ring with its large load-bearing surface takes over the function of the metal sleeve hitherto used (Fig. 4). <IMAGE>
Patent DE-3347170-A1 (DE)
Title: Terminated paper-insulated medium-voltage cable
Inventor: BIERMANN ERNST-ARTHUR DIPL ING
IPC: H01R13/53
Filed: 1983-12-27
Abstract: Paper-insulated medium-voltage cables are at the moment connected to one another or terminated using a special technique which is costly in terms of assembly. In the case of plastic-insulated cables, it is already normal to use fittings based on push-on technology. The object therefore exists of making this push-on technology useable for the termination of paper-insulated medium-voltage cables, as well. In this case, the aim is to terminate the insulating-oil filling of the paper-insulated cable at the connecting zone and to create a sealing zone which prevents the insulating oil emerging. This object is achieved by means of a hose (4), which consists of oil-resistant elastomer and is pushed on over the paper-insulated core (13) of the cable end, the one end (42) of the hose being seated on the metallic outer sheath (11) and in this case ensuring the necessary sealing function. The other end (41) of the hose is seated on a sealing zone (21) of a connecting sleeve (2), which sealing zone (21) is equipped with an annular groove region. The electrical coupling of the field-control deflector (61) to the metallic outer sheath (11) takes place via an electrically conductive element (5). <IMAGE>

Patent DE-3404127-A1 (DE)
Inventor: RICHTER LUDWIG
IPC: H02P8/00
Filed: 1984-02-07
Abstract: Control circuitry for a self-synchronously driven step motor under closed loop control includes, for determining the rotor position, a technologically simplified back EMF waveform detector circuit which includes fewer than five operational amplifiers, and preferably only one operational amplifier, and which delivers, for each motor phase, a back EMF signal and the negative thereof. Use can be made of these signals individually or in various combinations, with the aid of a back EMF selector arrangement and an adder connected thereto, for controlling the stator field. By sum and difference formation of back EMF signals by the adder and by assigning such signals each to a respective energization state of the motor phases, the rotor can be moved by half-steps as well as full-steps, to provide a finer degree of control. Additionally it is possible with such circuitry to detect the end position of the rotor and its maximum degree of overrunning, which yield values that can be used for achieving desired damping of the rotor.

Title: Optical fibre with an optical coupling system
Inventor: BLUDAU WOLFGANG DR RER NAT
IPC: G02B6/42
Filed: 1984-02-29
Abstract: The optical fibre has at its end a fused optical system consisting of a cylindrical rod (3) made from optical material at the free end of which a lens (4) is formed by fusing. The cylindrical rod (3) has a larger diameter than the optical fibre (1), and the lens (4) has a larger diameter than the rod (3). The lens (4) is, furthermore, aspherically constructed, i.e. the radius of curvature is smaller at its free end than that of the remainder of the lens. Production is performed in such a way that after fusing a ball to the rod (3) a further small drop of material is fused onto the ball at the front. The optical system obtained provides optimum coupling in and out of the optical power and has a very slight reaction on the radiation source. <IMAGE>

Title: Test head holder for a self-propelled internal pipe manipulator
Inventor: ROEHRICH HEINZ DIPL ING
IPC: G01N29/265
Filed: 1984-04-04
Abstract: The invention relates to a test head holder (2,21,25,27,28) for a self-propelled internal pipe manipulator having a support member for test devices. The arrangement of ultrasonic test heads and their displacement along pipe walls together with the holder and adjusting devices have thus far been too bulky to be used in the interior of pipes. For this purpose, the invention provides that a holder (21) is mounted on the support member so that it can be rotated by motor about an axis (24) of symmetry in line with the axis of the inside diameter of the pipe, and that a support comb having at least one ultrasonic test head is mounted on the holder so that it can be displaced at right angles to the axis of symmetry. In addition, a level-measuring device (68), which is provided with a mechanical/electrical transducer and serves to reproduce the test position, can be mounted on the holder. A test head holder according to the invention is suitable, in particular, for use in ultrasonic testing by means of internal pipe manipulators. <IMAGE>

Patent DE-3433058-A1 (DE)
Inventor: KNOBLAUCH KARL DR ING
IPC: B01D53/04
Filed: 1984-09-08
Abstract: A process for adsorptive separation of gas mixtures which in addition to nitrogen contain at least oxygen, by the cyclic charging and discharging of carbon-containing molecular sifted coke, in which the pressurized gas mixture is fed to an adsorber and in which the procedure is as follows: a) production of a pressure balance between the previously-decompressed adsorber and another pressure vessel; b) constant build-up of pressure in the adsorber to a final pressure by passing the pre-compressed gas mixture through it (production stage) and c) desorption of the adsorbed gas components by decompressing the adsorber. The product gas production takes place in only one adsorber. The product gas is then fed to a product gas store. The pressure balancing in the adsorber is effected with product gas from the product gas storage. The subsequent pressure build-up in the adsorber takes place in two stages, namely a first relatively rapid pressure-build-up stage to an intermediate pressure and a second relatively slow stage in which the pressure builds up to its final value.

Patent DE-3442664-A1 (DE)
Title: Hydraulic control arrangement
Inventor: SANDAU HARTMUT DIPL ING
IPC: B60T13/16
Filed: 1984-11-23
Abstract: The hydraulic control arrangement has a flow-control valve (16) and a brake device (51, 52, 71, 89). During a braking operation, the pressure medium delivered by the pump is controlled via the flow-control valve and a non-return valve (38) to the brake cylinder (89). In the process, pressure is exerted on the piston (52) together with slide (51), as a result of which the piston (52) is set in such a way that a control-oil flow from the pump to the tank is interrupted and the pressure medium can flow to the brake device. In order to obtain rapid and smooth charging of the brake cylinder (89), a disc (86) is firmly arranged on the free end of the piston (52). The disc (86) produces a restricting passage (87) between the non-return valve (38) and the brake cylinder (89). The additional (fluid) force exerted here on the piston (52) due to the pressure difference at the restrictor (87) produces a certain increase in the brake pressure. A rapid and steady pressure build-up in the brake cylinder is thus obtained.
