Title: Flywheel energy store
Inventor: SCHELLER WILHELM G
IPC: F16F15/315
Filed: 1982-08-03
Abstract: There is a flywheel energy store in which a flywheel (6, 8) which can rotate is seated on a vertical shaft (9), and a bearing of the flywheel is provided. In this case, it is desirable for the level of utilisation of the stored movement energy to be improved in that the bearing of the flywheel is improved, using simple means, by reducing the friction losses. This is achieved in that the flywheel is constructed as a magnetic ring structure (6) and a spacer (8) located between said structure and the shaft (1), and a magnetic bearing of the magnetic ring structure (6), which can rotate, is provided on a further, horizontal magnetic ring structure (2) which is arranged concentrically thereto. As a result of the use of the magnetic bearing, when the flywheel is set in rotation with a specific supplied energy, it can rotate for very much longer than when it is only on mechanical bearings. <IMAGE>

Title: Compressed-air system with a compressor which can be switched off automatically
Inventor: KALTENTHALER WOLFGANG ING GRAD
IPC: F04B49/02
Filed: 1982-11-10
Abstract: When a certain pressure level in the consuming unit is reached, the compressed air delivery from a compressor is switched off by interrupting the compressor drive. Interruption is effected by disengaging a mechanical clutch inserted in the drive of the compressor, by controlling a switching piston by means of the pressurised oil of the pressurised circular lubrication of the compressor. The switching piston acted upon by the oil pressure of the circular lubrication establishes a connection of the drive and the compressor thus delivers compressed air in this phase. When a certain compressed-air level is reached in the consuming unit, this pressure switches over a directional control valve, such that the supply of pressurised oil to the switching piston of the clutch is interrupted and the switching piston, relieved of pressure, switches over due to the force of a spring and the compressor comes to a standstill due to disengagement of the clutch. Compared to other switching devices, the device described as the advantage that not only does the compressor come to a standstill but that the pressurised circular lubrication is interrupted.

Patent DE-3304637-A1 (DE)
Inventor: SCHREINER HORST PROF DR
IPC: H01H1/02
Filed: 1983-02-10
Abstract: Electrical contact materials based on AgCdO with CdO as the main active component have proven to be particularly advantageous for low voltage switchgear in the power industry. However, when switching AgCdO contact materials, CdO, which is classified as toxic, can escape into the environment through burn-off. It is important, therefore, to keep the CdO content as low as possible in the contact material, or to exclude it completely. The contact material according to the invention is a sintered contact material consisting of AgSnO2 with at least two other metal oxide additives; namely, Bi2O3, CuO and optionally CdO. Relative to SnO2, these additives Bi2O3, CuO optionally CdO, amount quantitatively to a total maximum of 25 percent by volume of the total amount of oxide.

Title: Device for the wet copying of films
Inventor: SCHMITZER ANDREAS
IPC: G03B27/475
Filed: 1983-02-21
Abstract: The device for wet copying has, after the copying bath as viewed in the running direction of the film, a vacuum chamber (12, 13) in which at least one scraper (17, 18) acting on both sides of the film is provided. The connection line (14) to the vacuum source is arranged after the scraper, as viewed in the running direction of the film. Due to the liquid being scraped off the film and the lowering of pressure in the vacuum chamber, the film is largely freed of liquid, so that the subsequent drying zone, still necessary, can be very short in its longitudinal extent. <IMAGE>
Patent DE-3306821-A1 (DE)
Title: Controlling the tape tension in magnetic tape drives by processor-aided evaluation of the winding torques
Inventor: STADLMANN WILFRIED DR ING
IPC: G11B15/54
Filed: 1983-02-26
Abstract: In measuring technology, magnetic tape drives are used for data recording and storage, for example in the multi-track technique. For such measuring data recordings, a high tape running precision and high synchronising accuracy are required to ensure the time reference. The prior art takes the form of a mechanical or motor-electric type of drive of the rolls with an approximately constant torque. This results in a tape tension which is dependent on the diameter of the rolls. This has disadvantageous effects on synchronous running and tape-to-head contact. A high recording quality cannot be achieved, particularly in the first and last quarters of the supply of tape. Drives having tape-tension control by means of feeling levers or tape weighers with corresponding measured-value pick-ups are very complex or not feasible, for example in the case of cassettes. According to the invention, controlling the tape tension is achieved by sensing the instantaneous speed of both hubs. These measured values are evaluated in a processor and compared with a tape-specifically stored table. A correcting variable is calculated and suitably fed to the winding drive mechanism of the tape drive in such a way that an essentially constant tape tension over the entire length of the supply of tape is achieved. A tape location determination is possible independently of the tape speed.

Title: Method of storing the call data generated during call charge registration in telephone systems, in particular telephone private branch exchanges
Inventor: GOEHTZ MICHAEL DIPL ING
IPC: H04M15/34
Filed: 1983-08-23
Abstract: For storing the necessary call data during automatic call charge registration, the storage volume of the respective memory arrangement (SP) is divided up in a way corresponding to the possible end digits of a subscriber call number into 10 equal sections (0-9). The sections are in each case permanently assigned to a different end digit. In the individual, independently addressable subareas (B1/1; B2/1; B3/1;...) of each section, in each case only the call data for the calls made by a particular subscriber are stored. If one subarea (B1/1) is completely full, what is respectively the next free subarea (B3/1) is used for recording the further data generated for this subscriber (A). At the same time, the selection address (B3/1) of the subarea (B3/1) newly used for this subscriber is written in the memory area (B1/1) previously used for this subscriber (A). Access to the first subarea for a subscriber can be performed relatively quickly. Further accesses for the other subareas are made possible by means of the interlinking addresses. At the same time, good utilisation of the memory arrangement is achieved irrespective of the number of calls for a subscriber. <IMAGE>

Title: Circuit arrangement for a clocked voltage comparator
Inventor: FIEDLER HORST-L DR
IPC: H03M1/00
Filed: 1983-10-12
Abstract: The invention contains a circuit arrangement which carries out voltage comparisons with high accuracy and at high speed. For this purpose, a circuit arrangement consisting of a differential amplifier and two flip-flop circuits is used. It is particularly the special design of the first clocked, and thus novel, flip-flop stage in interaction with the circuit sections of differential amplifier and RS flip-flop, known per se, which, together with the integration of the voltage comparator in complementary MOS technology, provides for considerable improvement with respect to accuracy and speed compared with the prior art. It has been found that this integrated voltage comparator is suitable for detecting differential voltages of less than 0.2 mV within less than 20 ns at clock rates of up to 15 MHz. Such a circuit is therefore suitable, for example, for use in high-resolution analog/digital converters which are needed in communication engineering and in signal processing.

Title: Device for determining the distance from a metallic search object and device for carrying out this method
Inventor: EBINGER KLAUS
IPC: G01B7/02
Filed: 1983-12-01
Abstract: It is frequently necessary to determine the distance between a reference point and an object whose position displays, for example, the filling of a container. In accordance with the invention, use is made for this purpose of a search device in the form of a metal detector. In order for this search device to respond exactly to the object, the more so if metallic parts are situated in its environment, the object is provided with a tuned LC circuit. This LC circuit damps the electromagnetic oscillations emitted by the search device so strongly and with such a steep rising edge that the distance between it and the reference point can be precisely determined. As a result, it is possible to reach a conclusion on the filling of the container or another variable to be determined.
