Title: Process for manufacturing bellows for slideways
Inventor: ABKER EBERHARD
IPC: B29C65/02
Filed: 1982-07-07
Abstract: In a process for manufacturing bellows which are intended for covering slideways and guideways, all the stiffening strips to be processed are first laid in the associated outer folds. Subsequently the stiffening strips that are to be inserted are pushed together and in the pushed-together position heating of the stiffening strips takes place from outside. After the contact areas have reached their softening temperature, the stiffening strips are pressed together before cooling from inside into the tips of the folds against an external abutment. Cooling then takes place. After cooling a permanent welded connection has formed in the region of the outer folds between the stiffening strips and the material of the bellows body. With this process as many stiffening strips as required are simultaneously welded to the bellows body.

Title: Circuit arrangement for generating axle counter pulses for axle counter systems
Inventor: SCHMIDT HARALD DIPL ING
IPC: B61L1/16
Filed: 1982-09-27
Abstract: In order to generate axle counter pulses for axle counter systems in railway safety technology, a track device is used with AC-fed transmitting circuits and receiving circuits associated therewith. The useful reception voltage present in each receiving circuit and any steep-edged interference signals present are fed to a converter circuit in order to detect the positive summation envelope curve of the useful reception voltage and of all the steep-edged interference signals. The converter circuit consists of a half-wave rectifier circuit with a first diode (D1) and a capacitor (C1) as charging circuit. Connected in parallel with the capacitor (C1) is a discharge circuit which is briefly switched on at regular intervals as a function of the phase position of the useful reception voltage. A further circuit which permits an electrical simulation of the interference signals on the basis of the evaluation of the steep front edges of the interference signals is connected to this converter circuit. The interference signals which can be represented in this way are fed to a differential amplifier (V2) together with the signals of the summation envelope curve. Said amplifier transmits exclusively interference-free useful signals to an evaluation device (AG) for further processing. <IMAGE>

Patent DE-3241856-A1 (DE)
Title: Method of identification by the reading of an identity card
Inventor: PUETTER PAUL STEFAN DIPL PHYS
IPC: G07C9/00
Filed: 1982-11-12
Abstract: There are at the present time countless instances, in which access or entry is made dependent on whether the authorising identification code is read off from an identity card in an identity-card reader. These include, for example, automatic cash dispensers, access control systems or data terminals safeguarded by identity-card readers. In principle, the possibility of a falsification of the identity cards used cannot be excluded. The object of the invention is substantially to restrict the possibility of use of a falsified identity card. This object is to be achieved in that, during the reading of the identity card, an automatic change of the identification code takes place. The change of the identification code is transferred to the identity card. If, after a falsification, the original is used before the falsification, the falsification is worthless, since the identification code has changed. If the falsification is used before the original, the authorisation of the original is cancelled in view of the changed identification code. It can then be seen from this that a misuse has taken place in the meantime.

Title: Method and apparatus for determining the moisture content and temperature of mineral and/or organic mixtures
Inventor: FLUEGEL WOLFGANG-ALBERT DR
IPC: G01N27/22
Filed: 1984-04-03
Abstract: The invention relates to a method and an apparatus for the combined determination of soil moisture content and temperature using a specially developed measuring cell which comprises a sensor and which determines the moisture content of the substrate by measuring the moisture-dependent variations in the capacitances of a sensor capacitor and measures the temperature using a temperature-dependent semiconductor current source. An electronic circuit compensates for parasitic capacitances and the effect of the temperature of the measuring medium, while the sensor design, in conjunction with selected materials, eliminates any electrolytic effect due to the salt content of the water in the soil. The virtually simultaneous determination of the temperature also makes it possible to allow for the effect of the temperature-dependent viscosity of the moisture to be measured.
