Abstract: Es ist bekannt, bei elektromagnetischen Relais die Kraft-Weg-Charakteristik dadurch zu messen, daß mit einem spitzen Meßtaster gegen den Anker gedrückt wird. Dabei beeinträchtigen Positionsfehler der Spitze des Meßtasters die Meßgenauigkeit. Um eine genaue Messung der Kraft-Weg-Charakteristik ohne großen Positionierungsaufwand vornehmen zu können, wird am Anker (4) ein erhabener Meßpunkt (11) vorgesehen, der an dem Niet (12) zur Befestigung der Kontaktfeder (6) angeformt sein kann. An diesem erhabenen Meßpunkt (11) kann mit einem Flachtaster (10) gemessen werden, ohne daß dieser mit seiner Achse genau positioniert werden muß. Derartige Relais erlauben insbesondere in der Großserienfertigung eine einfache Kontrolle der Kennwerte.

Abstract: In known beam generators, the service life of directly heated boride cathodes is limited by their thermally disadvantageous retention. It is therefore proposed that the cathode be clamped directly underneath the cathode tip, rather than at the lower end of the crystal shaft, as has been normal until now. The retention, according to the invention, of the boride cathode ensures that the crystal is only insignificantly hotter in the region of the clamping plane than at the electron-emitting tip. …<IMAGE>…

Abstract: Hitherto, grinding of a plastic or metal surface always had to be carried out using an abrasive and a polishing material. The novel process produces a boehmite of such a grain size and structure and having low copper contents which are suitable for use in soft polishes in which both abrasive and polishing effects are desired in a single formulation. A process of this type comprises the following steps: provision of a caustic aluminate lye having an Na2Ofree:Al2O3 molar ratio K of less than or equal to 1, this lye containing copper ions in an amount not more than 50 mg/l; heating of this lye to an elevated temperature of at least about 150 DEG C; cooling of the lye under essentially static conditions, whereby the aggregates of alpha-aluminium monohydroxide are deposited, and isolation of these alpha-aluminium monohydroxide aggregates. Use in soft polishes.

Abstract: The high voltage generating apparatus includes a flyback transformer (2) to be employed in television equipment and has a circuit for stabilizing a high voltage output. This circuit comprises an additive voltage generating coil (21), a reference voltage generating circuit (3), a voltage detector (9), a comparison amplifier (22), a switching circuit (23) and a voltage multiplying rectifier circuit (42). The reference voltage generat­ing circuit (3) generates an inclined voltage in the flyback time of the horizontal deflection cycle and the voltage detector (9) detects a mode of the high voltage output. The comparison amplifier (22) compares an inclined voltage and a detection voltage and generates a control signal. The switching circuit (23) operates with the control signal. With this operation, an additive voltage generated by the additive voltage generating coil (21) is supplied to the high voltage coil (12) of the flyback transformer (2) through the voltage multiplying rectifier circuit (42). The voltage to be supplied compensates the voltage fall if the high voltage output and accordingly the high voltage output is stabilized.

Abstract: A known traction slip control and vehicle speed limiting device, referred to below as ASR/GB device, operates with a valve arrangement which comprises a combination of directional control valves. In order nevertheless to guarantee comfortable traction slip control, the known ASR/GB device has a system comprising orifices and additional volumes. Since this system has to be specifically adapted for different types of vehicle, adaptation of the known device can be complicated and expensive. 
<??>In order to make the known ASR/GB device adaptable to different types of vehicle by simple means, the invention proposes to employ a valve arrangement (17) with pressure modulation dependent on the level of the control signal supplied and to design the electronics (3) of the ASR/GB device in such a way that it outputs to the valve device a control signal which is just sufficient to eliminate spinning or the exceeding of the maximum permissible vehicle speed.

Abstract: A shelving unit is concerned which has a support frame, which can be moved in front of the shelves, for a raisable and lowerable charging and withdrawal device. The support frame (3) is designed as a frame which is open at the bottom and has vertical guide profiles (4) for a lifting frame (9) which is guided in a raisable and lowerable manner in the support frame (3), which lifting frame is extendable telescopically at the bottom from the support frame (3). This lifting frame (9) in turn has travel rails (10) for a charging and withdrawal table (5) which can be moved at height in the lifting frame (9). There is thus the possibility of using a support frame (3) having ground clearance so that the region below the support frame (3) for the material flow remains free. However, a satisfactory charging and emptying also of the lower shelf compartments (3) below the support frame (3) is achieved by the telescoping lifting frame (9) and the charging and withdrawal table (5) moveable therein. <IMAGE>
