Patent DE-3230134-A1 (DE)
Title: Swivel chuck for lathes
Inventor: HUEBL GERHARD
IPC: B23B31/16
Filed: 1982-08-13
Abstract: In a swivel chuck for lathes, it is intended to be possible for the workpiece to be indexed into a new machining position in as short an indexing time as possible in a simpler construction of the swivel device. To this end, one chuck jaw is connected to a swivel pin (8) of square cross-section, on which contact surfaces (20, 29) of swivel members (13, 24) mounted in parallel on both sides of the swivel pin (8) act. Thus the swivel pin (8) is actuated during the forward and return stroke of the swivel members (13, 24). Therefore only two strokes are necessary; this means short indexing times and thus an acceleration in the production sequence. <IMAGE>

Title: Bowden-pull window lifter for vehicles with a pane arrangement on one side
Inventor: KUESTER KLAUS
IPC: E05F11/48
Filed: 1982-11-13
Abstract: In Bowden-pull window lifters for vehicles, in the doors of which the window pane is not arranged centrally, but offset on one side towards the vehicle interior, there is a problem of making it possible to mount the upper end of the guide rail in the door in a simple way. The invention solves the problem in that the guide rail is equipped at its end which is upper in the position of use with a stop, pin or the like which engages positively into a corresponding holder of the door outer panel and which forms together with this holder a stationary connection. The guide rail therefore no longer has to be screwed firmly at its upper end, but can simply be inserted.

Title: Push gear for the switch blades of a toy railway
Inventor: HERZER KUNO
IPC: A63H19/32
Filed: 1983-03-21
Abstract: The push gear for the switch blades of a toy railway is mounted below the table top supporting the railway, such that a pin connects the armature, which can be pushed back and forth by remote control or manually, to the switch blade slide. The subject matter of the invention is mainly characterised in that a lever, hinged to the armature, is coupled by means of a coupling member, e.g. a rotatable vertical shaft, to the switch blade slide (e.g. a connecting rod), and in that the coupling member is indirectly mounted in bushes (e.g. in an inserter) centrally in a bore hole of the table top. One of the advantages of this design for model-makers consists in the fact that simple round bore holes in the model plate are sufficient for assembly. <IMAGE>

Patent DE-3326006-A1 (DE)
Inventor: IGNATIUS GEORG
IPC: G10D3/02
Filed: 1983-07-19
Abstract: In such bodies, in particular resonance bodies for musical instruments and the like, there is the problem of being able to adjust the spectrum of natural frequencies in the sense of an accentuation or attenuation or of a balanced variation in certain specifiable frequency ranges. In this connection, the vibration behaviour of the solid body is governed by the spatial, i.e. one- to three-dimensional distribution of the vibration parameters, especially the elastic deformation rigidity and the density or mass per unit area, based on, for example, the surface of the vibrating body. To solve the problem, it is proposed to arrange the spacial distribution of the vibration parameters in accordance with a subdivision (G, G1) having a plurality of superimposed series (R, R1, R2 ...) of regions of increased or reduced deformation rigidity, vibrating mass, vibration damping, surface curvature or bulging, or the like. At the same time, these regions are arranged essentially in an equidistant manner within a series. As an alternative to this or in conjunction with it, a subdivision with regions of the above type is suitable, the distances of the regions from one another being in the ratio of the members of a harmonic series. <IMAGE>

Title: Two-pole earth-contact plug socket for the floating closing and opening of the plug connection
Inventor: BRACHT WERNER
IPC: H01R24/76
Filed: 1984-04-03
Abstract: In the case of the two-pole earth-contact plug socket, an operating element which is arranged in the centre of the plug socket and acts on a switch ensures that the plug socket is floating when the plug is withdrawn. The connection of a commercially available plug socket base (4) and of a commercially available fast-switching snap-action switch (1) to a common assembly enables a particularly simple construction of a waterproof plug socket. A plunger (2) which is inserted in the plug-in receptacle (3) is effectively connected to the end (9) of a plug (6) so that the switch (1) switches during insertion and withdrawal of the plug as long as the plug pins (7) are still located in a deep position in the plug sockets (19). In consequence, the plug socket is also suitable for a region where there is an explosion hazard. <IMAGE>

Patent DE-3420395-A1 (DE)
Title: Composite profile, e.g. for windows or facades
IPC: E06B3/263
Filed: 1984-06-01
Abstract: A composite profile, e.g. for windows or facades, has two light-metal profile rods which are interconnected via individual connecting elements, forming an intermediate heat-insulating insulation space, and which are provided with mutually opposite longitudinally running profile slots, into which the connecting elements in the form of small blocks or bolts are inserted in a clamping fit. In order, with simple construction of the composite profile, both to achieve an equalisation of the thermal stresses arising from unequal heating of the interconnected profile rods, and to guarantee that, when great loads occur, a slip-free shear-resistant connection of the two profile rods is present, the arrangement is made in such a manner that the two head parts of each connecting element in each case have a metal tip which is coaxial with the axis of rotation and which, when the connecting element is turned in the profile slot, can be pressed into the respectively opposite profile web and that the connecting elements can be clamped together with the flanges, which delimit the respective profile slot, laterally tiltably by a small amount.
Patent DE-3422810-A1 (DE)
Title: Forging press
Inventor: MOSSEK JOHANN ING
IPC: B21J13/10
Filed: 1984-06-20
Abstract: The invention relates to a method for the operation of a forging press with two manipulators which serve to guide an elongate forging, are arranged on opposite sides of the forging tools and each have a manipulator carriage, which is moved in the feed direction of the forging, and a pair of gripping tongs which is displaceable in a hydraulically damped fashion relative to the respective manipulator carriage in the feed direction of the forging. In order to achieve constant step lengths and a better forging result, a predetermined feed movement matched to the precalculated lengthening of the workpiece is imparted to the pulling manipulator carriage and, after each forging stroke, the pair of gripping tongs of the pulling manipulator carriage is automatically reset to its zero position. The deflection of the pulling pair of gripping tongs relative to its manipulator carriage caused by the lengthening of the workpiece is simultaneously taken up by the pair of gripping tongs of the pulled manipulator. In the pulled manipulator, the respective total tong deflection is measured and converted into a correction of the feed movement of this manipulator until the zero position of the pair of gripping tongs is correct again.
