Title: Method for backing up data in the event of a power failure in mains-powered telephone terminals, in particular telephone stations with answering machines
Inventor: LEISTNER RUDOLF
IPC: H04M1/64
Filed: 1982-01-15
Abstract: The invention relates to a method for backing up data in digital telephone stations with answering machines when a sudden mains power failure occurs. This entails in particular the retrieval of information, following a mains power failure, at a defined storage point which guarantees the output of complete information. The storage point is to be activated when a mains power failure signal is present. The mains power failure signal is obtained by extracting a DC voltage from the existing mains voltage half-waves via an RC component, which DC voltage becomes lower in the absence of a half-wave and thereby controls an electronic switch in such a way that the above-mentioned storage point is activated during information retrieval following a mains power failure. This invention can essentially be used in mains-powered terminals which contain information which can be retrieved from data stores.

Title: Process for producing coded coins
Inventor: RUDOLPH GUENTHER DIPL PHYS DR
IPC: A44C21/00
Filed: 1982-02-09
Abstract: Due to the increasing significance of automatic dispensers for goods and services, it has been endeavoured for some time to design coins and tokens in such a way that unauthorised imitation is ruled out, or at least made so difficult that the production of forgeries is no longer worthwhile. In this context, it has become known to provide coins of non-magnetic base material with ferromagnetic material particles, without having specified for this a production process which can be realised technically and commercially. According to the invention, a process for producing coded coins and tokens is proposed which is characterised in that one or more particles of a ferromagnetic material in platelet or strip form is welded onto the cylindrical surface of a punched-out coin blank by means of a laser beam and impressed into the base material by upsetting. In this way, coins and tokens can be provided with one or more exactly arranged coding points, which can be used in correspondingly designed coin testers in addition to the usual test criteria for distinguishing from inferior foreign coins or forgeries. The imitation of such coding would be possible only with considerable effort which does not bear any relation to the value of the coin, so that there is no longer any incentive for fraudulent use of automatic dispensers.

Title: Dental X-ray device
Inventor: IMAZATO MINORU
IPC: B21D22/20
Filed: 1982-02-19
Abstract: Dental X-ray device with a panorama X-ray tube having a mouthpiece intended for insertion in the oral cavity for exposing an object to X-rays. The mouthpiece houses a target. A window-like opening restricts the X-rays emitted around the mouthpiece axis to an X-ray irradiation field adapted to the object to be recorded. For simple adjustment of this irradiation field, the mouthpiece is provided with a beam positioning which directs a beam of visible light onto the object. <IMAGE>

Title: Control arm arrangement for individual wheel suspension of unsteered axles, preferably for vehicle trailers
Inventor: SCHULZE JUERGEN DIPL ING
IPC: B60G21/05
Filed: 1982-04-16
Abstract: The invention relates to a control arm arrangement for individual wheel suspension of unsteered axles, preferably for vehicle trailers with a pivotable transverse control arm provided with a wheel carrier and capable of swivelling via the flexible control arm bearings about an essentially horizontal axis. The aim is to produce a simple design solution, which when cornering deflects the control arms in the direction of the curve with the same steering angle ( beta ). This meets the object of increasing the travelling stability and preventing the risk of swerving. The object is achieved according to the invention in that the rear control arm bearings lying opposite one another on an axle are firmly connected to the vehicle frame, the bearing bushes permitting axle tilting, whilst the front control arm bearings are rigidly connected to one another by way of tension/compression elements but elastically supported in relation to the frame, the elastic profiles being designed to be soft in an axial direction and hard in a radial direction. <IMAGE>

Patent DE-3235888-A1 (DE)
Title: Combustion engine
Inventor: BISCHOFF HANS
IPC: F02B53/00
Filed: 1982-08-13
Abstract: The combustion engine corresponds approximately in its mode of operation to a four-stroke four-cylinder Otto engine. This means that there are four power strokes for every two revolutions of the crankshaft. In the version shown here, all four possible power strokes coincide after each half revolution and can therefore be regarded as one power stroke, it thereby being possible to make corresponding reductions in the dimensions of the working chambers (displacements) for the same power. In the case of this engine, there are therefore, to be precise, 16 power strokes for every two revolutions of the crankshaft. This engine can be used in all known possible applications, whether stationary or non-stationary, in which combustion engines are employed. Fuel consumption is lower than in all known combustion engines. In addition, this engine does not make any demands on the knock resistance (octane rating) of the fuel.

Title: Process for dewatering a peat bath suspension

IPC: B01D36/02
Filed: 1983-03-31
Abstract: For the economical and environmentally-friendly recovery and transport of the solid matter of a peat bath suspension or of a similar aqueous homogeneous suspension having a low solids fraction of 2 to 5%, principally of organic fibres, by dewatering, it is proposed to pass the suspension (1) to be dewatered continuously through the following process stages:   a) a static filtration stage having arched or inclined screens (4), where the suspension is essentially separated from the fraction of free water to give a water content of 90 to 94%, b) through a first mechanical double screen press stage (1<1>), where the suspension, only under the pressure of the tension of the screen belts (9 and 10) is separated off from the rest of the free water and a part of the water freely bound in the fibres to give a water content of less than 90%, and c) through a second double screen press stage, where the screen belts (9 and 10) are passed between press rolls (12, 13 and 14) and where the suspension is separated off from a further part of the water freely bound in the fibres to give a water content of 80%, and the filtrate produced in the process stages being initially clarified (22) and only being fed to a waste water system (31) at a content of at most 1 g of solids in 1 l of water. The fraction separated off in the clarification, still containing fine particles, is returned to the process for dewatering. <IMAGE>

Abstract: Bei den heute beim NTSC- und PAL-System vorgesehenen Methoden zur Übertragung der Chrominanzsignale kommen häufig Phasenfehler vor, die zu einer Farbtonverfälschung führen. Für deren Beseitigung wird bei PAL ein doch sehr erheblicher Aufwand erforderlich. Beim NTSC-System wird der Phasenfehler durch einen Tastendruck korrigiert. Bei der vorliegenden Erfindung wird die Phase als Codiermittel nicht verwendet, sondern es werden die Werte für den Farbton und für die Farbsättigung seriell mit einem Wechselstrom gleicher Frequenz übertragen.
