Title: Coating calendered plastics web - with e.g. fleece layer, using roller application techniques
Inventor: DENGL HANS
IPC: B32B5/24
Filed: 1973-01-20
Abstract: A calendered plastics web is coated with another layer or fleece by passing the calendered foil as a coating cylinder where a coating paste contg. an activating substance is applied, then the covering layer is added.

Title: Process and plant for pressing multi-layered asbestos-cement sheets - sinusoidal pressure cycle ejects water and interlocks fibres
IPC: B28B1/52
Filed: 1973-09-22
Abstract: Process and plant for pressing multilayered asbestos cement sheets utilises sinusoidal water expulsive pressure cycles to interlock fibres effecting better integration of constituent layers. The plant consists of a press with vertically opposed horizontal platforms, the lower perforated through to water extraction conduits and the upper raised, lowered and thrust by hydraulic jacks and via accumulator permitted free fall. The pressure cycle is initiated by free fall of the upper plate followed by gradual application of pressure until the magnitude is repeated when the load is removed. This process has a drawn down effect on the fibres 25 local to drain outlets re-aligning fibres sinusoidally longitudinally and interlocking the layers.

Title: Rigid rear axle for car - with trailing arm linked by cross bar in asymmetric bearings
Inventor: SCHNEEWEISS MANFRED
IPC: B60G21/05
Filed: 1973-12-07

Title: Large open plastics vessel pressed from blank - obtained by closing one end of extruded tubular moulding
Inventor: SCHUETZ UDO
IPC: B29C57/10
Filed: 1974-04-18
Abstract: Method of making hollow thermoplastics mouldings which are closed at one end is as follows: first, a tube is extruded to approx. the shape required, then this is pinched in at one end while still plastic and weldable and thus closed; the resultant shell-like structure, while still warm and plastic, is then placed in a mould and pressed to give it its final shape. Pref., thickened portions are produced in the initial tubular blank by varying the extrusion procedure, to give a reserve in the subsequent shaping; finally, excess matl. may be cut away. After final moulding, one part of the mould may be removed and the resultant moulding directly sprayed with water to cool it. The advantages of uniformity of thickness obtainable by injection moulding are obtd. in a moulding of a size which could not be injected easily.

Title: Parallel axis rotary piston engine - has air blown static oil gasket fed by compressed air from engine chambers
Inventor: KEYLWERT JOHANN
IPC: F01C19/12
Filed: 1974-05-13
Abstract: An interior and parallel axis rotating piston combustion engine is constructed such that between the exhaust outlet channel (16) and oil circulation galleries of the combustion engine, a static oil gasket (26) with a sealing region (20) has sealing air supplied to it, of which a part is directed into the exhaust gas stream as secondary air. The air supply to the sealing region (20) of the gasket (26) is taken from one of the working chambers of the engine during the compression sequence and is transferred to the gasket (26, 20) through automatically controlled channels. This produces a labyrinth type seal and also a buffer zone of reverse flow.

Patent DE-2436447-A1 (DE)
Title: Backflushing rapid filter for water prepn. - having separate slotted distributors for backflushing air and water
Inventor: WIEDERHOLD WILHELM DR
IPC: B01D35/24
Filed: 1974-07-29
Abstract: Backflushing filter, esp. open or closed rapid filter for water prepn., uses combined water and air sparing to backflush and having base supporting layer under the filter sand layer. On the base of the filter vessel air and water distribution pipes are located having slits which are smaller than the particle size of the filter bed. Their flow resistance is so arranged so as to give a closely knit and uniform distribution of the backflushing medium without the supporting layer or filter bed and ingress of sand into the tubes is prevented without further aid. Inside and along the length of the air distribution pipe is a second pipe having calibrated openings for the air. The pipe can be divided internally into separate chambers. The filter is of esp. use for preparing drinking and general purpose water. Such filters where backflushing is used, require special methods to ensure adequate distribution of the air and water, which can include a special intermediate floor to the bed called a jet tray. The system gives a very much simpler construction.

Title: Composite sheets with foam polyurethane core between covers - and fabricated into contoured upholstery by direct cover to cover welded seams
Inventor: SHORT RONALD
IPC: B32B27/00
Filed: 1974-10-25
Abstract: Composite sheets incorporate a layer of polyurethane foam enclosed between a layer of fabric and a polyurethane film. Seams are made by local heating to disperse the foam and weld the film directly to the fabric cover on the other face of the foam. Used for mfr. of upholstery coverings, esp. for covering vehicle seats or for lining vehicle interiors e.g. covering wheel arches, lining doors, cab roofs, etc. Welded seams can be generated more rapidly than stitched seams.

Title: Layered insulating panels for indoor swimming pool buildings etc. - incorporates hard foamed plastic layer coated with aluminium foil
Inventor: BENDER ROLAND
IPC: E04B1/62
Filed: 1974-10-28
Abstract: The cladding for the purpose of effecting both heat insulation and moisture screening on the inside, is provided in the form of large-surface multi-layered assembly elements in panel form. The panels are made by applying a coating of water vapour impermeable material, in the form of an aluminium foil sheet (3), by means of an adhesive (2), on the insulating layer which consists of hard-foam plastic (1).

Title: Reducing scatter influence in X-ray detection - by measuring difference between readings with and without grating
Inventor: KOWALSKI GUENTER DR ING
IPC: A61B6/06
Filed: 1974-11-02
Abstract: Appts. for reducing the influence of scattering in an X-ray emitter and a set of detectors comprises a grating between the emitter and detectors, pref. between the emitter and the object inspected; this grating is moved sideways (in its own plane) and the difference in the maximum and minimum readings during movement, or between the readings with and without the grating in the path of the beam, is measured. Pref. a chessboard grating is used, in which the grating constant corresponds to the distance between adjacent detectors. The influence of scattered radiation is considerably reduced, using relatively simple equipment.

Title: Cellular building panels continuously produced from several layers - pressed together and rolled to cellular structure then faced
Inventor: WEISS HERBERT
IPC: B27N5/00
Filed: 1974-11-07
Abstract: A method of making building panels, plates, mats etc. from granular fibrous, bituminous and/or powdered raw materials bonded together with a binding agent to give a pasty starting material is as follows: the pasty material is first continuously rolled into a wide, thin band, then this band is compacted as it moves forward and then one or both faces are embossed to give a cellular or similar structure, and then the sheet is cut into lengths. Preferably, the raw materials and binding agent are measured in batches, then mixed, then stored and then rolled. A number of separate wide, flat strips may first be rolled and then brought together, esp. with a continuous sheet of reinforcing material or fabric introduced between them. The resultant, combined, reinforced sheet may then be compressed, rolled to give it its surface cellular structure or similar hollow structure, and, after it is cut to length, may be faced with facing material and/or plastics sheeting. The method is relatively simple and economic. The resultant panels possess high stiffness and strength, good thermal and acoustic insulating properties and permit air circulation inside them.
