Patent DE-3118421-A1 (DE)
Title: Device for securing and controlling rail vehicles
Inventor: JAKOB WOLFGANG DR ING
IPC: B61L3/12
Filed: 1981-05-09
Abstract: The subject of the application is a device for securing and controlling rail vehicles in which all the information necessary for travelling safely is transmitted to the vehicles via railway line-side transmission devices (PD1,...PD9) acting in a dot-shaped manner. The transmission takes place in the form of data telegrams from the railway line to the vehicles in one direction only. In order to detect failures of individual transmission devices, the data telegrams from the line-side transmission devices are provided with codes which form a continuous sequence and each of which is stored on the vehicle up to the respective next transmission device. In each case two transmission devices with codes which match one another in pairs can also be arranged near to one another. In order to increase the availability of the device, control information for a railway line section is issued which extends in each case at least up to the next but one transmission device.

Title: Device for switching on a cutting roller
Inventor: ROLLER MANFRED DIPL ING
IPC: B26D5/02
Filed: 1981-10-19
Abstract: The invention relates to a device for switching on and switching off a roller cutter which is seated on a movable carriage and is brought into and out of engagement with a cutting ruler for the purpose of cutting paper. The object of the invention consists in bringing the roller cutter into and out of the cutting position using the energy of the carriage without electromechanical auxiliary means. According to the invention, the object is achieved in that the carriage is moved into a position which lies outside the travelling region during the printing and at the same time brings the roller cutter (2) by means of a slide (1) from the stable rest position to the likewise stable cutting position, and vice versa. The advantage of the invention lies in a design of the cutting device which is simple and hence not susceptible to trouble. <IMAGE>
Patent DE-3142025-A1 (DE)
Inventor: MICHEL DIETER ING GRAD
IPC: G03F1/88
Filed: 1981-10-23
Abstract: A method and apparatus for generating exposure masks is disclosed which markedly reduces the number of required process steps. A plurality of recording originals are successively reproduced in reduced form on a photosensitive recording substrate. These reduced size images are adjusted and placed in registry with respect to one another by means of a computer. In order to achieve this desired result, the computer calculates from the prescribed desired coordinate values and the measured actual coordinate values of index marks included on the recording original, an angle  DELTA  phi through which the recording original must be rotated to achieve the desired orientation. The computer then acts to determine the corrected actual coordinate values of the diagonal intersection point and from these the coordinate values at which the recording substrate is to be positioned to achieve the desired in registry reproduction of the reduced size image of the recording original. This process is repeated for a number of recording originals, reduced size images of which are successively reproduced on the recording substrate, which is in each case appropriately positioned by means of the computer. The recording substrate is then developed, and the desired exposure mask is produced by photolithographic techniques.

Title: Solenoid valve
Inventor: STEGMAIER ALWIN
IPC: F16J15/3252
Filed: 1982-04-07
Abstract: A seal for a switching plunger bushing through a separating wall between an electromagnet (1) and a valve (9) is proposed. The seal is formed by a lip sleeve (15) which is inserted into a corresponding recess (14) in a supporting plate (8), with radial pretensioning. In consequence, an installation unit (8/15) is created. Axial bracing is achieved by means of an oversize of the sleeve body (18) with respect to the supporting plate recess (14) and by means of a correspondingly narrow axial gap on an installation point of the installation unit (8/15). The installation unit (8/15) ensures simple handling of the seal and the lip shape of the sleeve (15) ensures a pressure-dependent pressure of the seal against the switching plunger. The seal can preferably be used in solenoid valves for anti-lock braking systems in motor vehicles. <IMAGE>

Title: Support for an exhaust turbocharger
Inventor: PETROVSKY JAN DIPL ING
IPC: F02C7/20
Filed: 1982-07-16
Abstract: A support arranged on the housing of a reciprocating internal combustion engine is used to attach an exhaust turbo-charger. The support comprises a supporting arm and a tubular piece integrally connected to the latter, to which the outlet connection arranged on the turbine casing of the exhaust turbocharger is flanged. Such a support allows the fixing of exhaust turbochargers which do not have a casing specially matched to a support. The shut-off member of an engine brake can be mounted in the tubular piece. The rigid fixing of the tubular piece on the casing results in a precise interaction between the shut-off member and its actuating cylinder, which is likewise arranged on the housing of the internal combustion engine.

Filed: 1982-09-07
Abstract: In the process, thin layers of a metal, preferably gold or silver, are vaporised onto a substrate at a substrate temperature below 30 DEG C at a rate of 1 to 1.5 nm/sec. The layers, with their layer thickness of 20 nm, have an optical transparency in the order of magnitude of > 10 %, a layer resistance of < [lacuna]  OMEGA /unit area and their properties are not impaired even by heat treatment at temperatures </= 425 DEG C.

Filed: 1982-09-10
Abstract: 1 Gegenstand der Erfindung bildet ein Verfahren und eine Vorrichtung zum Schärfen und Reinigen von insbesondere profilierten Schleifscheiben mit Diamant- oder Schleifkörnern aus kubisch-kristallinem Bornitrid als Schleifmittel unter Anwendung eines Schärfblockes. Um bei möglichst geringem Aufwand an Schärfblockmaterial und an Zeitaufwand einen vorgegebenen Spannraum zwischen den Schleifkörnern reproduzierbar zu erzeugen, ohne Kräfte zwischen Schärfblock und Schleifscheibe hervorzurufen, die zu einer Beschädigung führen könnten, ist vorgesehen, die Vorschubgeschwindigkeit des Schärfblockes voreinzustellen und bei Erreichen einer eingestellten maximalen Vorschubkraft so weit zu reduzieren, daß die eingestellte Maximalkraft nicht überschritten wird. Die Vorschubgeschwindigkeit (v) wird dafür vorzugsweise nach Unterschreiten der einstellbaren maximalen Vorschubkraft auf einen voreingestellten Sollwert gebracht und unabhängig von der Vorschubkraft konstant gehalten, wenn die Vorschubkraft unterhalb des voreingestellten Wertes liegt. Die Vorrichtung für die Durchführung dieses Verfahrens weist dafür zwei miteinander gekoppelte Antriebe für den Schärfstein (2) auf, von denen mit dem einen Antrieb (4) die Vorschubgeschwindigkeit und mit dem anderen Antrieb die Vorschubkraft zu steuern ist. Dabei kann ein Antrieb einen Hydraulikzylinder (6) mit einem Hydraulikkolben (4) aufweisen, und es ist weiterhin vorgesehen, daß bei Anwendung mindestens eines Arbeitskolbens (3, 4) für beide Antriebe deren Kolbenstangen miteinander gekoppelt sind.

Title: Method of grinding a screw tap and grinding wheel for carrying out the method
Inventor: VOGELSANGER EMIL
IPC: B24B3/18
Filed: 1982-10-01
Abstract: In the grinding of a screw tap, the grinding of the thread and the chamfer is performed in two machining operations. The machining is effected with a grinding wheel in the same set-up of the screw tap on one and the same grinding machine. The grinding wheel is accordingly designed with at least one thread-grinding section and one chamfer-grinding section. Since the screw tap can be finish-machined on a single machine, non-productive time and the production costs are reduced.
