Title: Process for manufacturing toroidal magnetic strip-wound cores for residual-current-operated circuit-breakers, and use of said cores
Inventor: PFEIFER FRIEDRICH DIPL PHYS
IPC: H01F3/04
Filed: 1981-02-28
Abstract: A process for manufacturing toroidal magnetic strip-wound cores for residual-current-operated circuit-breakers (earth-leakage circuit-breakers) is described, which involves subjecting a toroidal magnetic strip-wound core, wound from a strip which has a thickness of from 0.05 to 0.3 mm and consists of a nickel-molybdenum-copper-iron alloy, to various heat treatments under a non-oxidising atmosphere. In order to improve the independence of temperature of the inductance shift in the normal operating temperature range of residual-current-operated circuit-breakers, according to the invention the use of an alloy is provided whose nickel and copper content in the binary system nickel-copper lies within the area delimited by the quadrangle A (76% by weight of nickel, 0% by weight of copper), B (78.5% by weight of nickel, 0% by weight of copper), C (70% by weight of nickel, 12% by weight of copper), D (70% by weight of nickel, 8.3% by weight of copper), whose molybdenum content z, in % by weight, for a given nickel content x in % by weight satisfies the condition 11 DIVIDED 30 (x-68) </= z </= 11 DIVIDED 30 (x-65.5> and which essentially contains iron as the remainder. A toroidal magnetic strip-wound core made of this alloy is first annealed for at least 30 min at from 900 to 1200 DEG C and is then, in accordance with the molybdenum content, tempered in such a way from 480 to 550 DEG C, that the magnetic anisotropy K1 at a temperature between -5 and +30 DEG C becomes equal to zero. Such toroidal magnetic strip-wound cores are particularly suitable as core-balance transformer cores for pulsed-current-sensitive residual-current-operated circuit-breakers with a tripping current of 30 mA. <IMAGE>
Patent DE-3107938-A1 (DE)
Inventor: DREISEITL WALTER DIPL ING
IPC: G01P3/489
Filed: 1981-03-02
Abstract: A method and apparatus are disclosed for providing improved rotational speed determination for a rotating shaft. Two probes positioned adjacent a circular disk which rotates with the shaft scan markings on the disk and generate four out-of-phase signals in response to rotation of the shaft. A switch, controlled by logic circuitry which detects intersections of the signals, develops a composite saw-tooth-shaped signal from the four signals. A counter counts the number of crossings of the composite signal with a reference "zero" value to develop a determination of the number of discrete angular positions traversed by the shaft during a specified time interval. A memory stores the value of the composite signal at the start of the time interval. Computation circuitry develops a rotational speed based on the counted number of positions, corrected by a factor derived from the difference between the stored value and the value of the composite signal at the end of the interval. Time control circuitry prevents the start or end of the time interval during switching and prevents switching during the start or end of the time interval.

Title: Device for the pneumatic threading of a thread into a two-for-one twisting spindle
Inventor: MIDDELMANN HEINZ
IPC: D01H13/10
Filed: 1981-03-11
Abstract: The pneumatic threading device for a two-for-one twisting spindle is accommodated in a thread-braking insert which is inserted into the two-for-one twisting spindle concentrically to the spindle core. The thread-braking insert has a compressed-air connection and air-supply channels which lead on the one hand to a threading injector arranged concentrically to the thread-guide channel and on the other hand to a device for putting the thread brake out of operation. A follow-up control installed in the thread-braking insert influences the supply of compressed air, in such a way that first the device for putting the thread brake out of operation and thereafter the threading injector is supplied with compressed air. The device for putting the thread brake out of operation is a spring-loaded cylinder/piston unit which can be loaded with compressed air. In an exemplary embodiment, the threading injector can be made in two parts, in such a way that one part, designed as an opening piston and loaded by a closing spring, closes the injector mouth. Compressed air acting on the opening piston opens the injector mouth after the thread brake has been put out of operation. In a further exemplary embodiment, the compressed air for the threading injector is conveyed via the device for putting the thread brake out of operation, the said device being designed at the same time as a control valve. The control valve is opened only when the thread brake is put out of operation.

IPC: E04F13/08
Filed: 1981-05-02
Abstract: The invention relates to a device for fastening a facade panel in front of the exterior wall (1) of the structure. The device can be introduced, by means of a fitting piece (2), into an adapted bore (3) of the exterior wall (1) of the structure and has a steel connection element (4) which is intended for connection of the facade panel and juts out in the mounted state of the device. In general, the facade panels are suspended on the mounted connection element (4). In order also to be able to use such a device in locations where the exterior wall (1) of the structure is configured as a masonry-structure wall or, for other reasons, cannot withstand high surface pressures, the fitting piece is designed as a concrete fitting piece (2) which consists of a concrete of high compressive strength and into which there is embedded a fastening element (6) which passes into the connection element (4). The concrete fitting piece (2) has a diameter (D) which is larger than the diameter (d) of the fastening element (6) by approximately a factor of from 2 to 10, preferably approximately 5. The surface pressures which the exterior wall (1) of the structure has to withstand when a facade panel is connected to the connection element (4) are consequently reduced in accordance with the exterior dimensions of the concrete fitting piece (2). The latter is, in general, provided with a reinforcement (8 and/or 9). <IMAGE>

Title: Image and method of producing it
Inventor: SCHMIDT-LANGHOFF HAJO
IPC: G03F5/00
Filed: 1981-05-15
Abstract: In an image having an image area which is countersunk in a plate surface and is of three-dimensional construction and in which lines of different depth and width for reproducing a picture enclose image-area components of different size between them, the lines are distributed in the form of a raster over the image area. In the vicinity of brighter contours of the picture, the raster has a lower density of image-area components than in the vicinity of dark contours. The raster is coloured as a function of the density of the image-area components. In a method for producing such an image, a raster of lines of different depth and width is countersunk in the image area. In the vicinity of brighter contours of the picture, the lines are so distributed that the image-area components lying between the lines form a relatively small component of the image area. In the vicinity of dark contours, the lines are so distributed that the image-area components lying between the lines form a relatively large component of the image area. The image-area components lying between the lines are coloured.

Title: Bougies for vaginal treatment
Inventor: PAULMANN RICARDA
IPC: A61M31/00
Filed: 1981-07-01
Abstract: A bougie for vaginal treatment is proposed, which differs in an advantageous manner from the known bougies in that, while in place, no dry surfaces can develop in the vagina. This is achieved by means of a stepped construction of the bougie (1) whose head (2) preferably consists of elastic material when it is positioned in a vagina of normal depth, and has an elastic foot limiting the depth of insertion. The bougie is used in the case of vaginites, for treatment following operations and vaginoplasty and the like. By means of movements produced by the body itself, the steps of the bougie cause a discharging of the wound exudation and vaginal secretions, the latter contributing to lubrication. The bougie is able to keep postoperative scars soft and to exert a massage effect on the vaginal wall.

Patent DE-3201366-A1 (DE)
Title: Heat treatment oven
Inventor: WITKOWSKI PETER
IPC: C21D1/767
Filed: 1982-01-19
Abstract: A heat treatment oven with an oven chamber and at least one burner is proposed, the oven chamber having, at a distance from the burner, a flue gas discharge duct which, either directly or via a heat exchanger and then with preheating of fresh air fed to the burner, returns flue gas diverted from the oven interior to an outer burner branch which surrounds the outside of the burner. The diverted flue gas is, utilising the burner as an injector, re-introduced into the oven chamber in the burner region. This results in a flue gas circulation which effects turbulence in the oven chamber. In addition, the energy content of the flue gas is utilised for preheating the air. Additionally or alternatively, the burner is connected to an exhaust gas duct of the same oven or of another oven, which carries hot exhaust gases otherwise uselessly discharged to the atmosphere, and these are recycled to the oven via the burner.

Title: Intermittent-motion control mechanism
Inventor: MUELLER LUIS
IPC: F16H29/02
Filed: 1982-02-06
Abstract: The invention relates to an infinitely variable intermittent-motion control mechanism in which an input rotary motion is converted into variable oscillations by mechanical means and the latter converted into an output rotary motion by means of one-way clutches. Whereas, in the case of known control mechanisms of this kind, each of the phase-offset converters produces a uniform output rotary motion for only about a third of an input rotary motion, the uniformity of the output rotary motion for the load travel in this control mechanism can extend to about five sixths of an input rotary motion, as a result of which more power can be transmitted. According to drawing 1 - Figure 1 - the disc (2) has, for this purpose, a groove (3) by which a uniform angular velocity of the swivelling movement of the levers (9 and 10) occurring during the load travel is produced with five sixths of its circumference and by means of the remaining sixth of the circumference of which the said levers are, for the idle travel, swivelled back into the starting position. <IMAGE>
