Patent DE-4222502-A1 (DE)
Inventor: SCHOEN OTMAR DIPL ING
IPC: F15B1/14
Filed: 1992-07-09
Abstract: The invention relates to a hydro-store with a storage casing (10) in which two partial chambers for media to be separated from each other are formed by a separating diaphragm. Because there is at least one other separating diaphragm (22, 24) in the storage casing (10) arranged in such a way that the number of partial chambers (30, 32, 34) formed is at least one greater than that of the separating diaphragms (22, 24) and/or these partial chambers (30, 32, 34) are formed by at least one storage bubble which is sealed to the storage casing (10) along its outer periphery, the hydro-store has a wider field of application than prior-art types. It is in particular possible with the multi-chamber hydro-store of the invention to store energy more favourably for the same size than in a conventional store with only one separating diaphragm.

Title: Short-range radio device for detection of stolen vehicle - broadcasts modulated signal indicating unauthorised driving, for reception and demodulation by receiver operated by law enforcement agency
Inventor: DANZER LUDWIG DIPL ING
IPC: H04B1/04
Filed: 1992-11-06
Abstract: An antenna (22) on the vehicle radiates a high-frequency signal (30) from a transmitter (12) incorporating a carrier-frequency oscillator (16) and frequency modulator (18), triggered by an activator (24) connected to the ignition switch (26) and/or a manual tuner (28). If the vehicle is broken into and driven away, a receiver (14) installed in, e.g. a police car or frontier post, can detect the radiated signal at a range of the order of 100 to 200 m, and generate a visual and/or audible warning (40) in time for the stolen vehicle to be intercepted. USE/ADVANTAGE - Esp. in motor vehicle, radiated alarm signal is not liable to be disregarded (like an oversensitive acoustic alarm) but is reliably effective in event of theft.

Patent DE-4303559-A1 (DE)
Inventor: BAERENWALDT UWE DIPL ING
IPC: F21V31/00
Filed: 1993-02-08
Abstract: A rotating beacon with a base (10) which has an inner annular wall (13) and an outer annular wall (14) is proposed, onto which base (10) a translucent light cover (11) which covers a motor-driven, rotating reflector can be fitted. The inner annular wall (13) is connected to the outer annular wall (14) via ribs (15). Furthermore, the inner annular wall (13) rests with its lower end region in a circumferential fashion on an annular sealing arrangement (21) which seals off the interior of the rotating beacon from the outside, at least one first air vent (22) to the intermediate space (16) between the annular walls (13, 14) being formed at the lower end region of the outer annular wall (14). The intermediate space (16) has in the upper region at least one second air vent (18) to the interior. By means of this arrangement, water is on the one hand prevented from getting into the interior of the rotating beacon and on the other hand a vented interior is realized by means of which it is ensured that, for example, water which has entered can escape again quickly without the light cover having to be opened. <IMAGE>

Title: Control and monitoring device in rail vehicles, in particular in passenger coaches, which are combined to form a train
Inventor: POLLEE WINFRIED DR
IPC: B61L15/00
Filed: 1993-03-12
Abstract: The detection and control of operating states in rail vehicles, such as the diagnosis of axle bearings or fire detection and the heating and lighting control currently takes place either centrally in the train driver's cab or else autonomously in each vehicle individually. On the one hand this has the disadvantage that the necessary fixed addressing of all the monitoring and actuation points necessitates a fixed coach sequence and on the other hand there is no total overview of the operating states in the train. With the control and monitoring device according to the invention it is intended to permit control and monitoring of operating states, independently of the coach sequence, both in each rail vehicle independently and centrally in the entire train and also fault reports are to be received from the neighbouring coach or from any other coach. According to the invention, each control and diagnostic device 4 to 12 and 13 to 21 of each vehicle is to be connected to a control unit 1; 2; 3 for each vehicle, with which control units 1; 2; 3 each control device 13 to 21 can be actuated and which receives an output fault/alarm pulse of each diagnostic device 4 to 12, the control units 1; 2; 3 of all the vehicles being connected to one another via a communication line 22 and each control unit being designed so as to be capable of being freely addressed and optionally switched as a command control device. <IMAGE>

Patent DE-4321390-A1 (DE)
Title: Electrical component
Inventor: GOSEBERG WALTER DIPL ING
IPC: H05K7/12
Filed: 1993-06-26
Abstract: An electrical component having a housing made of plastic, for example the high-voltage transformer (high-tension transformer) for a television receiver, is frequently provided with sprung fingers having barbs by means of which the component can be inserted in a latching and positively locking manner into a printed circuit board or a chassis panel. It has been found that, during installation, particularly in the case of new types of materials for the plastic body having great hardness, such as glass-fibre reinforced plastic for example, the sprung fingers break off. In consequence, the entire component is no longer usable. This is particularly disadvantageous in the case of the relatively expensive high-voltage transformer for a television receiver. The object is to use simple means to ensure that the sprung fingers do not break off while the component is being handled. Essentially rigid projections, which form a stop are provided on each of the two sides of the housing in the direction in which a fingers is deflected. These projections limit the maximum possible deflection of the fingers to a non-critical level. For use in particular for the high-voltage transformer in a television receiver. <IMAGE>
Patent DE-4322253-A1 (DE)
IPC: E04G9/02
Filed: 1993-07-05
Abstract: A shuttering with shuttering boards (1) and connecting means for the same, namely connecting clamps (7) and connecting bolts (11) exhibits shuttering boards (1) with border profiles (2) which have a closed hollow cross-section and each has a stop (5), running on the outermost border of the shuttering board (1), projecting at right angles to the shuttering skin (4) and intended for sealed abutment against a corresponding stop (5) of a neighbouring shuttering board, as well as, on a retaining web (6) which is approximately parallel to said stop (5), engagements locations in the form of shaped recesses (8) for connecting clamps (7) which engage around the border profiles (2) of neighbouring shuttering boards (1). Furthermore, holes (10) for the introduction of connecting bolts (11) are provided at mutual spacings in the stop webs (5) of the hollow border profile (2), in the direction of the longitudinal extent thereof, which connection bolts have, in an end region, protrusions (12) which project radially with respect to the cross-section of the bolts and which engage behind the borders of the holes in the anchoring or locking position, while, in a position rotated with respect to this, it is possible to introduce and draw out the bolt (11) with its protrusions (12) since the holes (10) are slots or keyhole-like holes. The spacing and the size of the holes (10) corresponds to the analogous dimensions of such holes (10) on border webs (13), formed from flat material, of further shuttering boards (1), and the clear spacing between the protrusions (12) and a counter-stop (14), which is spaced apart axially therefrom and belongs to the connecting bolt (11), is approximately equal to the overall thickness of the flat border webs (13) or of one flat border web (13) and a stop web (5) of the border profile (2), with the result that shuttering boards with flat border webs (13) can be connected to shuttering boards with hollow border profiles (2) with the aid of such connecting bolts (11). Furthermore, shuttering boards with flat border webs (13) can be connected to one another with the aid of the connecting bolts (11) and, likewise, shuttering boards with hollow border profiles (2) can be connected to one another by means of connecting clamps (7). <IMAGE>
