Title: Electronic typewriter with a connection for a screen memory unit
Inventor: SCHWEER LUDGER
IPC: G06F1/16
Filed: 1988-07-01
Abstract: For electronic typewriters with a connected screen memory unit, to avoid light reflections on the screen surface and to produce equally good legibility of the displayed data, it is necessary that the screen or screen surface should be adjustable relative to the eyes of the operator. For this purpose, holding devices are already known, but because of their high cost of production and required maintenance, they are unsuitable for cheap mass production. The object of the invention is to produce an electronic typewriter with a screen memory unit, so that an ergonomically optimal adjustment of the screen is possible by simple means. For this purpose, the screen (7) is arranged on a swivel arm (14) so that it can be rotated and tilted, and the swivel arm (14) is carried in a bracing arm (15) of a holding device (16) with a standing surface (17), so that it can be rotated. The standing surface (17) can optionally be rigidly connected to the left or right side of the base plate (18) of the typewriter. The screen (7) can be conveniently swivelled by the operator into a first final position over the typewriter (1) and a second final position next to the housing (20) of the typewriter (1). By simple handling, the screen (7) can be adjusted ergonomically optimally. In an advantageous version, the memory unit (8) in the bracing arm is ... Original abstract incomplete. <IMAGE>

Patent DE-3827365-A1 (DE)
Inventor: SCHULZE ECKEHART
IPC: F03C1/06
Filed: 1988-08-12
Abstract: The rotor (18) of an axial piston engine (10) is connected to the engine shaft (16) so as to remain fixed during rotation and during sliding and is supported on the engine housing (91) without play in the axial direction. The cross-sections of control passages (96) alternatively overlap with the control chambers (99) of the engine housing (91), which are put under pressure or relieved of pressure, thus causing the driving pressure chambers (37) of the rotor (18) to be alternately pressurized and depressurized. Said control channels (96) are arranged on a control disk (88), which is linked in a rotationally fixed manner with the driving part (19) of the rotor (18) that delimits the driving pressure chambers (37) but can for compensation sway or be axially shifted relative to said part. Said control disk (88) has a metallic sealing surface (118), inside which the outlet openings (98) of its control channels (96) are situated, and with which it slidingly and sealingly rests against a sealing surface situated on the housing side, inside which the outlet openings (98) of the control chambers (99) are situated. Said control disk is forced to rest against the sealing surface (114), situated on the housing side, by elastic sealing elements (34), which ensure the sealing contact of the driving pressure chambers (37) with the housing chamber containing the rotor (18), whereby said sealing elements (34) are thus strongly pre-loaded in the axial direction.

Patent DE-3837437-A1 (DE)
Inventor: BUSCHMEIER KONRAD
IPC: B60Q1/30
Filed: 1988-11-04
Abstract: The invention relates to a device for receiving the rear lights of a vehicle, said device consisting of a centre part receiving the number plate and the number plate lights and of two outer parts receiving the rear signalling lights, it being possible to insert the outer parts and the centre part into one another. Devices of this kind have been manufactured until now from plastic using the injection moulding method or deep-drawing method and require a great deal of working expenditure due to their double wiring or open walls. A further disadvantage consists in the fact that a multiplicity of individual parts makes a complete assembly by a person not skilled in the art impossible and its impact-absorbing property was not provided in the previous types. In order to avoid these disadvantages, the central part which receives the number plate and the number plate lights and the outer parts which receive the two rear signalling lights are constructed as blowing moulded bodies. This device is predominately used in the construction of motor vehicles or trailer vehicles. <IMAGE>

Patent DE-3842694-A1 (DE)
Inventor: HEISS RAINER DR
IPC: H04J3/06
Filed: 1988-12-19
Abstract: There are time-division multiplex communication systems in which digital signals which are asynchronous with the pulse frame and consist of successive blocks whose beginnings are marked with sync words are inserted into the pulse frame. The resulting jitter of the sync words ("waiting-time jitter") is reduced by a circuit which derives from the clock of the received sync words a sync signal (SY) that exhibits less jitter than the clock of the received sync words. According to the invention, the circuit contains a measuring device which measures the time intervals (N) between the sync words, a filter (F) which takes the average (N') of the time intervals (N), and a signal generator (S) which forms the sync signal (SY) from said average (N') in such a manner that the pulse period of the sync signal (SY) is equal to said average (N').

Patent DE-3941329-A1 (DE)
Inventor: FRICKE HELLMUTH
IPC: B61L7/10
Filed: 1989-12-14
Abstract: At least one detector (M1, M2) is allocated in the setting mechanism to each go-signal light (F1, F2) of a light signal, which detector assumes a first switching state (-) when the signal light is illuminated and a second, active switching state (+) when the signal light is not illuminated; the second, active switching state of all detectors characterises the illumination of the stop-signal light (H). The illumination of a signal light (e.g. F1) is detected on the light signal via a light-current-controlled monitoring device (IG1) and transmitted with a pre-defined polarity to the setting mechanism via the feeding lines (LF1) of this signal light and the feeding lines (LH) of at least one de-activated signal light (H). When the stop-signal light (H) is activated, the monitoring voltage derived from the associated monitoring device (IG0) is applied to all detectors (M1, M2) via its own feeding lines and the feeding lines of all go-signal lights, out of phase with the DC voltages which can be injected via the monitoring devices (IG1, IG2) of the go-signal lights (F1, F2). When a go-signal light (e.g. F1) is activated, a voltage-controlled monitoring device (UG1) assigned to this signal light applies a monitoring voltage in phase with the DC voltage of the current-controlled monitoring device (IG0) of the stop-signal light via the feeding lines (LH, F2) to all detectors (M2) with the exception of its own detector (M1); an out-of-phase monitoring voltage derived from the light current is applied to this detector via changeover switches (K1.1, K1.2). A logical evaluation device evaluates the switching states of the detectors. The advantage of the circuit is that uniform switching modules (Mo1, Mo2) are used on the light signal for all go-signal lights without any individual connection with switching means of other signal lights. The circuit is intended for monitoring light signals in the railway network. <IMAGE>
