Patent DE-3247618-A1 (DE)
Title: Method for tightening screw (bolted) connections
Inventor: POLZER BERNHARD
IPC: B25B23/14
Filed: 1982-12-23
Abstract: The method can be used to tighten screw connections via the rotation angle and the torque or via the tensile yield strength. In the case when tightening is controlled by torque and rotation angle, as well as in the case when it is controlled by tensile yield strength, the gradient of the torque/rotation angle curve is determined during screwing. The screwing operation is interrupted if the instantaneously determined value of the gradient before a prescribed rotation angle/torque region is reached is equal to an upper or lower prescribed gradient value. The two prescribed upper and lower gradient values are used to provide a reliable safety stop by means of which improper tightening of the screws is immediately detected and indicated by generating the signal.
Patent DE-3248247-A1 (DE)
Inventor: BRONSTERT BERND DR
IPC: G03F7/105
Filed: 1982-12-28
Abstract: Layers of a photopolymerisable composition for producing relief and printing forms contain (a) at least one photopolymerisable, olefinically unsaturated compound, (b) at least one photoinitiator which initiates a rapid photopolymerisation in the layer on exposure, and (c) a combination, which does not initiate any appreciable photopolymerisation in the layer on exposure, of (c1) a soluble acridinium, phenothiazinium, phenoxazinium or phenazinium dye and (c2) a mild reducing agent for the dye (c1). The layers give improved relief structures (better intermediate depths) in manufacturing relief forms and are also advantageous in manufacturing relief gravure printing forms. On exposure they give tint changes which facilitate the assessment of the exposed layers before development.

Title: Film welding unit for domestic film bags
Inventor: OHLSEN HEINZ-JUERGEN
IPC: B29C65/74
Filed: 1983-04-09
Abstract: An electrical heating device is disposed in the unit housing of a film welding unit, which heating device has a support strip onto which the pressure strip of a pivot bracket mounted on the unit housing can be pressed. A two-layer film web can be welded between the support strip and the pressure strip to form a closed bag, a suction fan for sucking the air from the film bag before the welding thereof being disposed in the unit housing and the suction fan being connected to a suction nozzle projecting from the housing. In order to be able to suck the air reliably from the filling zone of the bag even with incompletely filled film bags, the suction nozzle has an unsupported nozzle shaft permitting turning up of the film bag approximately as far as its bag base.

Title: Steel pipe section for a pile to be driven
Inventor: VERSCH JOSEF DIPL ING
IPC: E02D5/52
Filed: 1983-05-27
Abstract: The invention relates to a steel pipe section which with several identical pipes produces a pile to be driven. One end of the pipe section is reduced in wall thickness from the outside and the other end of the pipe section is reduced in wall thickness from the inside. There is a shoulder surface in the pipe section at least at one end at the distance of the wall-thickness reduction from the end face of the section and in addition there are inner and outer stepped surfaces. In order to provide a connection for pipe sections which on the one hand is easy to drive and on the other hand can also be withdrawn again, the intention being for the pipe sections to be reusable and to be simple to produce, it is proposed that the stepped surfaces (4, 5) have encircling annular profiles in such a way that the profile (9) of the outer stepped surface of one pipe section (1) engages in the profile of the inner stepped surface (14) of another pipe section (13) upon assembly, and the pipe section has several longitudinal slots (11) on the end (3) with the outer stepped surface and is likewise provided with several tapped radial holes on the end (12) with the inner stepped surface. <IMAGE>

Patent DE-3336491-A1 (DE)
Title: Optical coupling device
Inventor: GLANIA GUENTER DIPL ING
IPC: G02B6/28
Filed: 1983-10-07
Abstract: The invention relates to an optical coupling device having a substrate constructed in a rotationally symmetrical fashion, e.g. a cylindrical substrate, on which a waveguide fibre is wound like a coil. The substrate is surrounded by an optical device which embraces the waveguide fibre, which is wound like a coil, over a large range of solid angle. This coupling device permits a relatively high coupling out of the radiation guided in the waveguide fibre as a consequence of the fibre curvature, without the latter having, however, to assume values which reduce the service life of the fibre.   <IMAGE>

Title: Vacuum operated brake booster
Inventor: FELLINGER ROLF DIPL ING
IPC: B60T13/57
Filed: 1983-12-10
Abstract: In the case of a vacuum operated brake booster, a transverse element (41) is provided which limits the axial mobility of the valve piston (4), interacting with a disc valve, in relation to the timing case (2) and which furthermore ensures that, in the release position, the timing case (2) always adopts a certain position in relation to the booster housing. In order to allow the transverse element (41) to bear on the fixed stop with as little jarring as possible, it strikes on a cheek of rubber elastic material, which is part of the slideway ring which seals off the booster housing from the timing case (2). The transverse element (41) itself is formed from a sheet metal blank of essentially U-shaped design, the two parallel legs (36, 38) and/or the parallel fork arms (26, 27) being provided with notches (17, 18) which, for the purpose of holding the transverse element (41) in its shaft in the timing case (2), interact with corresponding lugs (44, 45) which are provided on an adjoining part, for example the timing case (2). <IMAGE>

Filed: 1984-01-16
Abstract: The invention relates to a firearm (shooting weapon) in the case of which, in order to prevent relative displacements, the cheekpiece is provided with a rough surface in the main region in which it makes contact with the head of the person shooting. The rough surface is intended to be constructed as a perforated grid.

IPC: C06B21/00
Filed: 1984-04-03
Abstract: A method for manufacturing plastically bonded propulsive powders and explosives by means of an extruder which comprises a housing with at least one entry opening, under certain conditions a solvent supplementing opening, two co- or counterrotating screw shafts and a forming head. The method makes possible continuous production with minimal binder components of 4-6 percent. Firstly, the plastic binder in a fixed, soluble or suspended form is added by means of an entry opening for a period of time until the screws float in the plastic binder without opposing friction and without friction with the walls. The components of the propulsive powder, or correspondingly the explosive material in crystalline form, are added in steadily increasing proportions with a simultaneous reduction of the portion of the plastic binder and finally, the mixture ratio is held constant.

Title: Apparatus for driving bodies in liquids or for moving liquids
IPC: B63H11/02
Filed: 1984-06-06
Abstract: In technology the problem arises in the moving of bodies in liquids or even in the moving of liquids that only a low efficiency can be achieved during the force transmission, since a large portion of the expended energy is lost in overcoming frictional resistance.
