Patent DE-4318367-A1 (DE)
Title: Metal-encapsulated high-voltage switching installation
Inventor: KOCH HERMANN DR
IPC: H02B13/035
Filed: 1993-05-28
Abstract: A current transformer (3) having a secondary winding (4) which coaxially surrounds a high-voltage conductor (2) is provided inside a metal-encapsulated high-voltage switching installation. In order to keep the electromagnetic noise pulses which occur inside the metal encapsulation (2) away from the secondary winding (4) of the current transformer (3), said current transformer (3) has a first screening body (6) which is conductively connected at its first end (5) to the encapsulating housing (1) and is arranged between the secondary winding (4) and the high-voltage conductor (2). At its second end (7), the screening body (6) is connected to part of the encapsulating housing (1), with the interposition of an insulating layer (8). The first screening body (6) can be radially constricted or expanded by means of an adjusting device (11, 12, 13, 14, 19) in the form of a collar (9) which can be constricted, as a result of which the insulating layer (8) can be compressed or expanded. The electrical capacitance which is formed between the first screening body (6) and the encapsulating housing (1) can thus be varied by varying the thickness of the insulating layer (8). This makes it possible to vary the frequency response of the capacitor (which is formed in the region of the insulating layer (8) and acts as a filter for the electromagnetic noise pulses) such that as few noise pulses as possible reach the secondary winding (4) of the current transformer (3). <IMAGE>

Title: Process and apparatus for the desorption of a moisture-adsorbing material
Inventor: KHELIFA NOUREDDINE
IPC: F24F3/14
Filed: 1993-07-01
Abstract: The invention relates to a process for the desorption of a sorbent by an air stream transported by a fan, which air stream is heated before entry into the sorbent. In order to decrease the desorption time it is provided to set the mass of the air stream in dependence on the exit temperature of the air stream exiting from the sorbent in such a way that when a preset temperature limit value is attained, the mass of the air stream is reduced and the desorption is continued with an air stream heated to a higher temperature. The process is suitable in particular for the desorption of sorption reactors in coolant-free air conditioning units.
Patent DE-4323482-A1 (DE)
Inventor: GEHRING MANFRED DR
IPC: E04F13/06
Filed: 1993-07-14
Abstract: The invention relates to an edge protecting border (11) as corner reinforcement for the filler coat which is applied onto the heat-insulating layer, serves as a carrier for the exposed plaster layer and is reinforced with plastic-reinforced glass-fibre mats (GFK). In order to provide an edge protecting border (11) with increased stability, in particular dimensional stability, along with simple production, it is provided that the angled border profile (17) comprises a laid glass-fibre or natural-fibre strip (1, 12, 5) as laid reinforcing strip, the laid reinforcing strip (1, 12, 5) being formed by at least two intersecting layers which are laid one above the other and comprise fibre bundles (2, 3, 6, 7, 8, 9), and the intersecting fibre bundle (2, 3, 6, 7, 8, 9) being linked to one another at their points of intersection by at least one further, separate thread (4, 10). <IMAGE>
Patent DE-4324478-A1 (DE)
Title: Rotational laser with improved visibility
Inventor: HINKEL RALF DR
IPC: G01C15/00
Filed: 1993-07-21
Abstract: The invention is based on the object of improving the visibility of rotating lasers, as are used in constructional levelling devices, in such a way that the line marked by means of them can also be applied without receivers. This object is achieved in that the laser beam does not rotate uniformly at constant speed but is moved in a jerky fashion. As a result, some regions appear brighter than others. This effect is reinforced if the movement changes take place at the same location during each revolution. On correct selection of the individual movement speeds and their synchronisation with the rotational angle, individual points can be detected by an observer instead of a continuous line. Nevertheless, the laser can be detected at any location using an electronic receiver, since the laser beam itself is naturally moving along a line. However, there is the difference that some regions are swept over more slowly than others and thus appear brighter as a result of the integration effect of the eye. <IMAGE>

Title: Method and device for monitoring vehicle tyres
Inventor: LUDEWIG MANFRED
IPC: G01S13/88
Filed: 1993-08-11
Abstract: The present invention provides a monitoring device for vehicle tyres (2) which contains a distance measuring device (3) for measuring the distance between a measuring surface (4) on the internal wall of the vehicle tyre (2) and a reference surface (5) which is fixed in relation to the rim (1) and for transmitting a corresponding output signal. Preferably, the distance measurement takes place in a contactless fashion with a wave transmitter and a wave receiver by determining the distance from a propagation time of a wave signal between wave transmitter, measurement surface (4) and wave receiver. It is particularly advantageous if the distance measuring device (3) comprises a transmission device for wireless transmission of the output signal to a receiving device which is arranged spatially separated from the respective vehicle wheel in the body of the vehicle or on the chassis of the associated vehicle. The monitoring method according to the invention provides for the detection of distances and the transmission of the detected distance values at different times in order to minimise interference influences on other electronic devices. <IMAGE>

Title: Information reproduction appts., esp. for audio data - picks up data stored on e.g. magneto-optical disc and stores data in ROM
Inventor: HAIKAWA YUKIHIKO
IPC: G11B27/00
Filed: 1993-10-12
Abstract: The reproduction appts. has a playback device (3-5) to playback information recorded on an optical or magneto-optical disc (1). A buffer memory (6) stores the played back information, and a readout circuit (7,8) reads the information stored in the memory at a transmission speed below the playback speed. A playback and memory control unit (10,11) operates such that when the amt. of information stored in the memory exceeds a set level, the storage of information from the playback device is stopped. The pick-up device is then moved back by a number of tracks representing a certain amt. of information. The new track position can then be read. When the playback device picks up information which follows the last information stored in the memory, the storage of information is resumed. ADVANTAGE - Lower power consumption. Less load from control circuitry. Longer operation in battery mode.

Title: Telescopic column
Inventor: OBERLEITNER HELMUT DIPL ING
IPC: B66C23/70
Filed: 1993-11-01
Abstract: The invention relates to a telescopic column which, in a fixed position or movable hanging on a crane, is formed from several tubular sections projecting into one another and guided on one another by means of guide rollers distributed over the periphery in radial planes. A working platform is fastened to its lowermost tubular section. In order to obtain considerable column rigidity even without a polygonal shape of the individual sections and produce the entire telescopic column more economically, it is proposed according to the invention that the tubular sections (3a to 3f) provided with a circular cross-section (12) each have an annular flange (14) at the ends (13a, 13b), and that several roller blocks (15), allocated to the annular flange (14), be provided in each case at least at one end (13a; 13b) of the respective tubular section (3a to 3f). The roller blocks (15) each have a rotatably mounted supporting roller (4) directed radially straight against the wall of the radially adjacent tubular section (3a to 3f). <IMAGE>
Patent DE-4339543-A1 (DE)
Title: Coin testing method
Inventor: BRELJE HEINZ VON DER ING
IPC: G07D5/08
Filed: 1993-11-19
Abstract: The method involves using a measuring probe, preferably inductive, which produces an analogue signal as a coin goes past it. The signal is digitised and compared with reference values to generate a `valid' or `counterfeit' signal. An `on' and an `off' signal are generated at times te and ta, near the beginning and end of the coin's travel, when the probe's signal rises above and falls near to the null level. The time separation of these signals is measured and compared with a reference value. Two measuring points (1,11) are chosen between the `on' and `off' signals. A time integral, calculated by sampling values between these points, is compared with a reference value. Also, the signal's gradient can be measured and compared with a reference value.
