Title: Lifting tackle for molten charges in steelworks - has two cables interconnecting ends of lifting bar not permitting tilting if broken
Inventor: KAMPA WILLI
IPC: B66D3/04
Filed: 1976-03-18
Abstract: The lifting tackle is used for carrying charges of molten metal in steelworks and has four multiple pulley blocks, two each end of the lifting bar (35). This bar has lifting hooks (36,37) and swings on an arm (38,39) each end. Two lifting drums (5,6) are provided each separately driven and carrying the multiple cables (1,2,3,4) used to operate the tackle. The cables are fixed (31-34) to different sides of the pulley blocks and pass over both blocks in turn, being interwoven between them. If a cable breaks, or one of the drive units breaks down, the lifting bar is not permitted to tilt or drop.

Title: Selector switch for (dish)washing machine - with conical switch knob with plug holes for engagement by spanner
Inventor: MEISSNER GERHARD ING GRAD
IPC: G05G1/10
Filed: 1976-04-09
Abstract: Selector switch for (dish)washing machine comprises a conical switch knob which has a socket device, e.g., 2 plug holes, for engagement by a spanner for actuating the switch knob. The peripheral surface of the switch knob is pref. concave. Only the operative in possession of the appropriate spanner can thus adjust the appropriate programme, and actuation by unauthorised persons is prevented. The appearance of a high-quality machine is maintained, and only the switch knob of the selector switch needs to be changed in order to use the machine for the above purpose.

Title: Safety shutoff valve - has thermally insulated body with two seats watchreceive valve heads mounted on central guides attached to pistons
IPC: F16K1/12
Filed: 1976-05-12
Abstract: The safety shut-off valve is intended for use with high temperature fluids or gases which may be injurious to health. The valve body is provided with internal thermal insulation and two valve seats. The valve heads are mounted on central guides attached to pistons. The pistons slide in cylinders attached to a central plate. The pressure of the actuating medium, which is higher than the valve upstream pressure, is admitted to the cylinders and pushes the heads onto the seats. The high pressure medium then fills the space between the valve heads increasing the pressure on the seats and preventing any leakage from the upstream fluid.
Patent DE-2622465-A1 (DE)
IPC: C04B28/02
Filed: 1976-05-20
Abstract: Hydraulically setting masses reinforced with artificial mineral fibres such as, for example, glass fibres can be converted into composite fibre materials having a low tendency to shrinkage and cracking, high abrasion resistance, high impact strength, tensile strength and flexural tensile strength coupled with advantageous long-term properties; in addition to binder, additives and water, the matrix of the masses contains aggregates having a grain diameter of up to 4 mm; the aggregates are present in a quantity of more than 20% by volume, relative to the volume of the finally placed mass; the water requirement of the matrix, increased by the aggregate, is compensated by a content of plasticisers and/or flow agents, and the adhesion, achieved by the aggregates and locally suppressed, between fibres and matrix is assisted by bundling of the fibres.

Title: Communication cable coupling inlet seal - has disc with concentric rings linked by radial arms to outer ring to allow adjustment for different cable sizes
Inventor: RADELOW WOLFGANG
IPC: H02G3/22
Filed: 1976-06-25
Abstract: The sealing disc for communicating cable coupling inlet ensures aligning of the cable which is then protected with a plastic compound. The provision of concentric rings (4) linked by radial arms (5) to the outer ring (2) allows adjustment for different sizes of cable to be centred in the bolted-upt cable joint. This is simply done by cutting out the unwanted rings to match the cable size. The disc is made of a flexible materials, such a polyolefin, and various types of moulds can be produced. As a result, the fitting is simplified and at the same time, retaining all rings ensures that the disc can be used as an end stop for the compound.

Title: Winch drive mechanism - has catch on first rotary component engaged with second coaxial one by friction control
Inventor: THERKELSEN HANS RICHARD
IPC: B66D1/22
Filed: 1976-09-28
Abstract: The winch drive mechanism incorporate a stationary housing and two components rotating on a common axis. The first component (33) is coupled to the second (41) by a locking catch (45) so that they turn together. The catch pivots on the first component so as to engage with the second. There is a friction-type control mechanism (47, 49, 50) acting between the catch and the stationary housing (27), so as to bring the catch into engagement with the second component. Typically this mechanism can have a spring ring (50) in frictional contact with the housing and turnable in relation to it, also a restrictor (47) between ring and catch. When the ring and the first component turn in relation to each other, this engages the catch.

Title: Duct mounted non-return flap used in waterworks - has additional frame part extending laterally to flow beyond sealing surfaces to act as damper on closing
Inventor: ELNRIEDER G
IPC: F16K15/03
Filed: 1976-10-23
Abstract: The non-return flap according to the design is used in ducts carrying considerable flow quantities of fluid, such as in waterwork pumping stations. The purpose of the design is to fit the flap assembly with a simple damping device. The flap (7) is fitted entirely or over part of its circumference with an angle iron (13) in such a manner that one leg of the angle is bolted to the edge of the flap, the other leg comes to rest against a step (8) when the flap is in closed position with gap (14) to spare. The actual sealing between flap and duct is provided by a strip (10). The angle iron acts as damping element becoming progressively effective as the flap approaches the step surface (8).

Title: Noise deadening prefabricated floating floor - has layers in load bearing support stratum separated to prevent noise propagation
Inventor: SIMON WALTER ING GRAD
IPC: E04F15/18
Filed: 1976-10-27
Abstract: The floating floor has a layered superstructure, in which the structural element in the load-distributing support layer is made up from two, or more layers, with a rebate accurately dimensioned so that when they are assembled grinding contact takes place only in the top layer. The other layers remain separated, to prevent occurrence of noises through open joint gaps. The layers are cemented together in such a way that they exert a noise energy absorbing effect through an elastoplastic connection. Squeaking, jarring and rumbling noises are subdued.

Title: Polymeric foil extrusion - applying additional stretching between intermediate and final cooling roll to an electrostatically charged foil
Inventor: BATYREV RUSLAN IVANOVITSCH
IPC: B29C48/07
Filed: 1976-12-23
Abstract: Flat foils and sheets are made from polymeric materials by extrusion from a slotted nozzle, electrostatic charging of the foil, stretching between nozzle and an intermediate roll and final cooling on a cooling roll. In the space between the intermediate roll and the cooling surface of the final roll, the polymeric web is subject to an additional longitudinal stretch. Method results in a substantial improvement of the quality of the flat foil produced. The device is simple in design. The manufacturing costs have been reduced by changes in the stretch deformation and the cooling of the polymer foil.

Title: Lightweight prefabricated building module - with embedded open web bar girders which protrude trhrough surface
Inventor: RAY ORLANDO F
IPC: E04B1/348
Filed: 1977-05-06
Abstract: The walls, ceiling and floor each include a thin, continuous layer of a concrete-like material having spaced open web bar girders embedded in one surface. The side-walls, the ceiling and the floor are assembled together with the bar girders extending outwards and are rigidly attached to one another for example by welding the ends of the bar girders to one another, thus forming a rigid, box-like building module. The building modules can be formed into a building by placing one layer of building modules with one sidewall of each module adjacent to but spaced from one side-wall of a different module. Concrete is poured into the space between the side-walls of adjacent building modules for forming a supporting column between the adjacent side-walls which is reinforced by the bar girders.
