Title: Composite structural element and process and apparatus for the production thereof
Inventor: LOESCH MANFRED DIPL ING
IPC: E01C5/22
Filed: 1987-04-01
Abstract: The intention is to provide an efficiently and cost-effectively producible composite structural element, the surface of which can be diversely configured, in particular in a manner similar to natural stone. The invention proposes a composite structural element, composed of a core part (2) consisting of a plastically deformed, hardened material, of a surface layer (3) comprising a multiplicity of small stones (4), and of an adhesive composition (5) which connects the individual small stones (4) of the surface layer (3) to one another and to the core part (2). The core part (2) can be prefabricated, for example, from concrete. By using the standard core part (2), the surface can be adapted to individual requirements, regarding texture and colour, by attaching various types of surface layers. The surface layer (3) preferably consists of natural-stone granules. In addition, stone dust (7) of the same type of stone, which completely covers the adhesive composition (5), can be scattered onto the surface layer (3). The composite structural element is particularly suitable for forming paths, squares and building facades. <IMAGE>

Title: Measuring device in motor vehicles
Inventor: NAGY IMRE
IPC: G01B7/31
Filed: 1987-05-18
Abstract: In a measuring device according to the preamble of Patent Claim 1, the body is permanently joined to the superstructure of the motor vehicle and the reference probe (feeler) is held in a carrier such that its position can be varied relative to the body, and the sensor is constructed in such a way that it determines the test distance between the carrier and the disc. The masses thereby moved are slight. The measuring device is therefore particularly suitable for use in driving operation for the purpose of dynamic measurement of a characteristic angle of a vehicle wheel.

Patent DE-3723700-A1 (DE)
Title: Device for regulating the closing sequence of two-wing doors
Inventor: SCHMIDT MANFRED
IPC: E05F5/12
Filed: 1987-07-17
Abstract: The invention relates to a device for regulating the closing sequence of two-wing doors, especially fire doors 1, with a standing wing 2 and with an overlapping passage wing 3 which are provided with door closers 12, 13. The passage-wing door closer 13 has a stop device. This is controlled by a control device having an actuating member 25, 26 cooperating with the standing wing 2 and having a transmission device 45 with a Bowden pull 46. In known devices of this type, the actuating member and the stop device are directly coupled to one another via the core of the Bowden pull, this resulting in assembly disadvantages on account of the necessary adaptation of the Bowden pull to the dimensions of the door. The invention eliminates these disadvantages by providing for the actuating member 25 to be arranged movably relative to the Bowden-pull core 47 and connected fixedly to the Bowden-pull sheath 48 surrounding the core 47, so that the sheath 48 acts as a control sleeve actuating the core 47. <IMAGE>

Patent DE-3731102-A1 (DE)
Title: Device for adjusting the backlash between gears of the change-gear train on the dividing attachment of a notching press
Inventor: KURZ OTTO DIPL ING
IPC: B21D28/22
Filed: 1987-09-16
Abstract: In a notching press, the size of the angle of rotation of each rotary step of the clamping plate can be adjusted by means of a change-gear train (17). In order, when changing the gears, to enable the adjustment of the backlash between the gearwheels (18, 19, 22, 23) to be carried out irrespective of the skill of the fitter, the step-by-step mechanism (13) can be displaced in the direction of the straight lines (21) connecting the centres of the gears (18, 19 and 22, 23 respectively) and fixed by clamping means (27). A pressure cylinder (33) for raising the step-by-step mechanism (13) on one side and a rack and pinion arrangement (39, 40) for displacing the step-by-step mechanism (13) are inserted between the dividing attachment (12) and the step-by-step mechanism (13). The pinion (40) can be rotated by actuating means (41). Since the step-by-step mechanism (13) has been raised on one side, the change gearwheel (18) and the mating gearwheel (19) touch when moved together at a point between the tooth head and tooth root. When the raising of the step-by-step mechanism (13) on one side is cancelled, the required backlash is thus obtained, with a simultaneous tightening movement of the clamping means (27). <IMAGE>
Patent DE-3731620-A1 (DE)
Title: Fastening of the air-filter holder of a ventilation system in a vehicle
Inventor: BUCHBAUER KARL-HEINZ
IPC: B01D46/42
Filed: 1987-09-19
Abstract: The air-filter holder and the cover have hitherto been fastened with common quick-action closures. Said quick-action closures are not always capable of bridging the large plays resulting from the permitted production tolerances, so that the exchange of the air filter in such cases involves great physical force by the fitter, which makes exchanging the air filter very much more difficult, in particular when there is inadequate access to the ventilation system.   To allow the air-filter holder to be released or fastened more easily, the air-filter holder (8) and the cover (6) have separate, play-bridging fastening means, the fastening means of the air-filter holder (8) having a much more marked play-bridging capability than the fastening means of the cover (6) and being designed as handles. The described fastening is suitable for ventilation systems in motor vehicles. <IMAGE>

Title: Method and device for the piecing of a spinning apparatus working with a pneumatic twisting member
Inventor: ARTZT PETER DR ING
IPC: D01H4/48
Filed: 1987-03-02
Abstract: For the piecing of a spinning apparatus working with a pneumatic twisting member (3), a thread end is conveyed back from the exit side through the twisting member (3) to a drawframe (2) and is then inserted laterally into the pair of exit rollers (23, 230) of the drawframe (2). From here, with a roving (1) being tied, the thread end is drawn off as a continuous thread through the twisting member (3). After the resumption of the thread draw-off, both the thread end and the roving (1) are exposed, between the pair of exit rollers (23, 230) of the drawframe (2) and the twisting member (3), to a compressed-air stream oriented essentially parallel to the nip of the pair of exit rollers (23, 230). For this purpose, a compressed-air nozzle (60) is arranged tangentially to the thread end (12) extending from the drawframe (2) to the twisting member (3) and is directed counter to the direction of flow of the compressed-air stream which causes the core twist of the thread end (12) and which is generated by the compressed-air bores in the twisting member (3). <IMAGE>
