Title: Microelectronic screen map
Inventor: BRANDT UWE CHRISTIAN
IPC: G09B29/10
Filed: 1984-02-14
Abstract: To overcome the disadvantages of conventional map systems and for the simplified, reliable, selective and time-shortened handling of voluminous information, orientation, search and determination services, particularly in the cartographic fields, the microelectronic screen map is constructed as a microcomputer in hand-held card format with a screen, the area of which predominates, and a supplementary verbal indication, is closed off by means of an operating tablet for alphanumeric and functional input and is used for visualising dimension-differentiated verbal information and colour graphics in which the selected start-destination connections are system-imminently automatically determined and optically identified as direction (guiding) paths. For use with a wider range of information, read-only memory capsules can be exchanged by the user with a simple operation and accurate fit in a fitting contact cut-out. For use with a wider range of applications, the functional units and blocks are tuned and aligned for the respective task and task-specific information and orientation requirement.
Patent DE-3408074-A1 (DE)
Title: Electromechanical pulse counter
Inventor: MITSCHIK HERBERT DIPL ING
IPC: G06M1/04
Filed: 1984-03-05
Abstract: The numerical drums (5) of the counter are rotated by means of a toothed wheel (6) and a driving pawl (4) which can be reciprocally moved tangentially to this wheel. When it is moved forward, the point (10) of the driving pawl (4) engages the toothing of the toothed wheel (6) and rotates it to the next nominal angle position. The driving pawl (4) is moved forward by means of a tension spring (9). It is pulled back by a magnetic coil (2). The forward movement of the driving pawl (4) is limited by a fixed stop (8) which impinges on a counterstop area (11) on the driving pawl. According to the invention, the stop area (11) extends obliquely to the direction of forward movement, as a result of which the point (10) of the driving pawl (4) resiliently engages in the tooth base between two teeth of the toothed wheel (6), without clearance, under the action of the tension spring (9). This achieves an accurate position of the numbers with little constructional complexity. <IMAGE>

Title: Electric heating device for the boiler of an absorber cooling system or of a heat pump
Inventor: HILLINGER ERICH
IPC: F25B33/00
Filed: 1984-08-24
Abstract: In absorption cooling systems, heat pumps or the like, it is usual to heat the so-called boiler of the system by means of an electric heating cartridge. This heating cartridge is mounted in a special metal sleeve or a cast part which is rigidly connected to the outer casing of the boiler. This arrangement is rather expensive and not infrequently leads to relatively high operating temperatures with correspondingly large thermal surface loads on the cartridge which shorten the life of the same. The aim was therefore to keep these high operating temperatures lower at the same time as simplifying the structure of the heating device. This aim is achieved in the heating device according to the invention in that the heating cartridge bears directly against the outer casing of the boiler and is covered by means of a hood-shaped reflection sheet which extends along the cartridge, is arranged at a given distance therefrom and is fastened together with the heating cartridge to the outer casing of the boiler. <IMAGE>

Abstract: The invention relates to a power supply device having an AC-voltage-supplied controllable converter (1) whose DC voltage output (6) is connected via a smoothing inductor (7) (which is arranged in a longitudinal branch) to the output (6a) of the power supply device, to which a load (8) is connected, and having a control device (4) which is allocated to the converter (1) and has a control input (5) for setting the operating mode of the converter (1). In order to achieve good smoothing of the voltage on the load (8) and to ensure that the load current (i2) falls quickly in the event of a short-circuit, a smoothing capacitor (11) is connected to the output (6a) of the power supply device and, in a parallel branch thereto, an inductor (12) is connected in series with a controllable switching element (13); a current detecting device (14) is connected with a current-sensitive input (15) in series with the load (8) and (via an output (20)) controls the switching element (13) into a conductive state as soon as the load current (i2) exceeds a predetermined current limiting value (I2G). At the same time, via its further output (21), the current detecting device (14) switches the converter (1) into the invertor mode. As soon as the load current (i2) reverses its flow direction, the current detecting device (14) switches the converter (1) into a zero-voltage mode. <IMAGE>

Title: Headrest for motor-vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1984-10-16
Abstract: A headrest for a motor-vehicle seat has an upholstery carrier which is surrounded by an upholstery element and is held relatively displaceably on at least one carrying rod. The lower plug-in region of the carrier rod, which is located in a seat rest, is received in a locking sleeve made of plastic. The locking sleeve receives in its sleeve head facing the upholstery carrier, in a drawer-like guide, a locking slide which can be pushed in towards the carrier rod counter to the restoring force of at least one spring and has a slider key made of plastic. The slider key holds the two attachment legs of a U-shaped metal frame penetrated by the carrier rod. The free attachment- leg ends of the metal frame are connected to one another via a locking web which engages with its inside in the carrier-rod locking notch facing away from the slider key. Each spring is supported both on the sleeve-head side and on the locking-slide side.   The entire locking slide arrangement is made simpler in design both in terms of construction and at the same time in terms of handling technology in that each spring forms a leaf spring tongue whose one support end is injection moulded, connected by means of the material integrally either with the sleeve head or with the slider key, and whose free end either forms a restorable stop with the locking slide or with the sleeve head.
