Patent DE-3900742-A1 (DE)
Title: Brake pad, particularly for spot-type disc brakes
Inventor: THIEL RUDOLF
IPC: F16D65/092
Filed: 1989-01-12
Abstract: Brake pad, particularly for spot-type disc brakes, with an insulating layer (1) arranged between a piston (3) and a lining carrier plate (2), the insulating layer (1) having a thermal and acoustic insulating effect on the lining-carrier plate (2) and being secured against displacement and twisting. To achieve the thermal and acoustic insulation of the insulating layer (1) on the lining-carrier plate (2), the invention envisages that the insulating layer (1) on the lining-carrier plate (2) should be formed by a sheet incorporating non-metallic organic materials and/or composite materials. Conventionally used interlayers have the disadvantage that, despite appropriate choice of materials and fastening to the lining-carrier plate, inadequate acoustic and thermal insulation and inadequate strength of the bond limits their performance. <IMAGE>

Title: Rodless multi-hole drilling and cutting unit
Inventor: TUTTASS EDMOND ING GRAD
IPC: E21B43/30
Filed: 1989-01-24
Abstract: A hydraulically operated drilling unit at the hole bottom which simultaneously drills at least two boreholes without rod or hose connection to the hydraulic pump and grouts the borehole connecting kerf in a pressure-tight manner. It receives pressure fluid through one of the self-produced boreholes for driving the hydraulic motor and for the feed. The fluid is used for the subsequent flushing and flows with the drillings through the other borehole back to the surface. The drilling unit consists of a hydraulic motor with gearing, the pivotable drilling and cutting devices, the grouting devices for sealing off the boreholes from one another, and the control devices. The drilling unit serves to produce bores, preferably in the earth's crust for extracting natural gas, crude oil and terrestrial heat, for underground coal gasification, and the like. It permits any borehole direction and varying borehole directions and reduces the amount of investment and time needed for bores.

Title: Vaginal protection
Inventor: KOCH GERHARD
IPC: A61F6/06
Filed: 1989-02-08
Abstract: The vaginal protection is intended as protection against diseases in men and women during sexual intercourse and against unwanted pregnancy. The vaginal protection is made of a soft, and yet rather dimensionally stable, impermeable material having an approximately sac-like design. Length and width of the vaginal protection are dimensioned such that an erected male penis can move therein, possibly with the aid of commercially available lubricants. The vaginal protection is inserted into the female vagina before sexual intercourse. A wide rim at the opening of the vaginal protection, a suitable shape and, where necessary, bands fastened on the wide rim for tying around the body of the woman ensure a firm seat of the vaginal protection in the vagina. The male penis is then inserted in the vaginal protection. After thorough cleaning the vaginal protection can be used several times. <IMAGE>

Title: Adjustment of motor vehicle  seat - is performed using lever designed to be self-locking to prevent overloading
Inventor: PREUSSNER MATHIAS
IPC: B60N2/235
Filed: 1989-12-08
Abstract: The seat of a motor vehicle or the seat backrest, is adjusted by a mechanism actuated by a lever (1). This lever is mounted on a shaft which passes through the hole (2). The lever has two arms (11,12) which extend in opposite directions from the hole (2). The shorter arm (11) is formed as a toothed quadrant (3) whilst the longer arm (12) forms a handle. A curved slot (5) is formed in the shorter arm (11) and receives a bolt (6). The position and dimensions of this slot are so designed that if an excessive load is applied to the lever the material adjoining the slot is distorted and clamps the bolt (6). Further movement of the lever is thus prevented and overloading of the teeth (3) is avoided. USE - Adjustment device for motor vehicle seats.
Patent DE-3941269-A1 (DE)
Inventor: DEHLING HELMUT DIPL ING
IPC: H02G15/113
Filed: 1989-12-14
Abstract: The invention relates to a cable sleeve for connecting and tapping cables, having a sleeve tube and sealing bodies which are inserted at the ends into the sleeve tube. In the cable longitudinal direction, the laterally divided sealing bodies each have two cable duct recesses which are spaced apart from one another at a predetermined distance.

Inventor: KOSLOWSKI THOMAS DR
IPC: C04B28/14
Filed: 1990-03-14
Abstract: In the process, a finely divided gypsum binder and fibres are mixed and the dry mixture is made up with mixing water. The made-up mixture is moulded to give a preliminary product. The preliminary product is pressed in a press to give the gypsum fibre board, which is hardened at the same time and thereafter, dried and optionally reworked. It is worked with a gypsum binder which consists of at least 60 % by weight of calcium sulphate alpha-hemihydrate and additionally up to 35 % by weight of calcium sulphate beta-hemihydrate and, optionally in the remainder, of inert constituents. 100 parts by weight of this binder mixture are mixed with at most 20 parts by weight of fibres. This mixture is made up with the mixing water until free from press water. The made-up mixture is introduced into a circumferentially closed mould and moulded in this to give the preliminary product. In the circumferentially closed mould, the preliminary product is pressed true to form so that the finished gypsum fibre board has a raw density of at least 1.5 g/cm<3>.

Title: Prodn. of active coke from untreated coal - by low temp. carbonisation on contact with heated solid heat carrier in rotary drum
Inventor: ECHTERHOFF JUERGEN DR
IPC: C01B32/336
Filed: 1990-06-08
Abstract: In prodn. of active coke from coal, broken dried coal is carbonised at low temp., without pre-treatment, in a rotary drum, in direct contact with heated, solid heat carriers, and after sepn. of the heat carriers from the low temp. carbonised coke, a fraction of defined grain size is sepd. by breaking up and sieving.

The heat content of the waste gases from the heater for the heat carrier is used to dry the coal. The active inner surface of the active coke is raised in known way with steam at 850-900 deg.C. USE/ADVANTAGE - The coke is used for the precision purification of coking plant gas prerefined in a gas washer, or as feed in a coking process (claimed). Active coke is also used in the final treatment of water, e.g. sepn. of phenols, and is applied also in e.g. sepn. of gases, e.g. SO2. The process is simple and cheap, and avoids fine grinding, premoxidn. and compacting of the coal.
