Patent DE-3907648-A1 (DE)
Title: Electronic travel time control device for motor vehicles
Inventor: SCHMIDT ANGELA
IPC: G07C5/04
Filed: 1989-03-09
Abstract: The electronic travel time control device according to the invention is intended for use for motor vehicles, in particular long-distance lorry traffic for monitoring whether the permitted travel times for the drivers during each 24 hour stretch are observed and whether the required rest periods are observed. It has previously been disadvantageous that the traffic police have not had sufficient means of monitoring the large number of long distance lorries travelling on motorways to ensure that the permitted travel times for drivers during a 24 hour stretch are being observed.   The invention is based on the object of providing an electronic travel time control device for motor vehicles which provides a round the clock display which can be clearly seen by anyone and indicates that the permitted travel time or rest time for drivers is being observed. The object is achieved in that signalling devices which can be controlled by an electronic circuit of the device and have the form of traffic lights are arranged at a point on the vehicle which can be clearly seen from outside the vehicle by anyone.
Patent DE-3910078-A1 (DE)
Title: Fluorescent tube, in particular for digit display
Inventor: MUELLER ROLAND
IPC: G09F9/313
Filed: 1989-03-28
Abstract: A high-voltage fluorescent tube (1) for digit display is subdivided by electrodes (2) into sections (a-f) which luminesce as required. It is known to bridge sections (a-f), which are not to luminesce, by means of a conductive connection of the two electrodes which in each case limit the section. It is proposed to activate instead those sections individually, which are to luminesce, in each case by means of the two electrodes which delimit the sections. Compared to the known solution, this has the advantage that no high voltage has to be switched mechanically. For the transformers (11-17) assigned to the individual sections (a-f) it is proposed to construct their primary sides in each case as blocking oscillator (21). Because of its high frequency, the transformers (21) can be constructed to be very small. The entire control (22-28) of the fluorescent tube (1) can then be combined with this fluorescent tube in a constructional unit, to which only a feed line (28) and a control line (46) for the control have to be installed. <IMAGE>

Patent DE-3914983-A1 (DE)
Inventor: SCHNEIDER BERNHARD DIPL ING
IPC: B30B9/12
Filed: 1989-05-06
Abstract: Wear of the strainer bars and/or screw segments in a screw press is monitored by measuring the current taken by the screw drive motor 9 and measuring the pressures in at least three areas 1, 2, 3 in respective thirds of the length of the strainer cage. The measured values are displayed (6, 8) and fed into computer 7 which compares them with starting or reference values. The wear results in a shift along the cage of the point where pressure is highest and a fall in the maximum pressure relative to motor current. The computer indicates this condition, and the strainer bars and/or screw segments are then replaced. <IMAGE>

Inventor: CLAES LUTZ PROF DR
IPC: A61L31/14
Filed: 1989-08-08
Abstract: A fastening means made of bioresorbable material, in particular a bone nail (1), a bone screw or a bone plate for fixation of bone fragments, has at least one closed receiving area (12), which is filled with an X-ray contrast medium (13). The receiving area (12) is a cylindrical bore which is provided in the bone of the bone nail (1) and which is closed with a plug (15) welded to the head (9).

Title: Testing distance sensor accurately for rapid changes - rotating transmitted beam w.r.t. curved object surface
Inventor: HASSE WERNER
IPC: G01S7/497
Filed: 1989-12-23
Abstract: A method of testing a distance sensor (1) involves producing a relative motion of the distance sensor w.r.t. a test object (3) by rotating at least part of a transmitted beam about an axis relative to a surface of the object. For different angular positions during the rotation the surface has a different distance from the rotation axis. A drive arrangement (8) is used to generate the rotation and the surface (4) is curved to produce the distance variations. USE - Accurate testing of distance sensors used with rapid distance changes and very short distances.

Patent DE-4002616-A1 (DE)
Title: Scanning channels for programming memory in VCR or TV - memorising channel frequency when synchronising circuit is detected, and de-tunes circuit if not
Inventor: CHOI SUNG GYU
IPC: H03J7/18
Filed: 1990-01-30
Abstract: The method of automatically scanning channels in the automatic programming of channel memory of a TV, VCR or the like, involves applying a tuning signal having a frequency associated with a specific channel to a tuner. The IF signal from the tuner is applied to a demodulation circuit (3) and its video signal is applied to a homodyne detection circuit. If the detection circuit detects a synchronising signal within 300 ms, the channel frequency is memorised by a processor.$ If no synchronising signal is detected, the signal is deturned in two steps of 0.25 MHz, and each deturned signal is detected for 30 ms. If no synchronising signal is then detected it is determined there is no broadcast channel corresponding to the frequency. The total time in which the determination is made is 360 ms.$ ADVANTAGE - Reduces scanning time. (16pp Dwg.No.1/6)

Title: Speed adjusting mechanism for portable drill - has switch lever movement constrained by spring clip exerting force
Inventor: NEUMAIER ANTON
IPC: B23B45/02
Filed: 1990-03-29
Abstract: The speed adjusting mechanism moves the plunger (13) of a motor speed control device backwards and forwards to produce a desired spindle speed. The switch lever (8) passes through a slot in the machine housing and pivots about a fixed pin (1a). Pushed onto the lever and moving with it is a spring clip (14) whose arms are forced apart so that a uniform pressure is exerted on the pin (10). Protuberances (14a,14b) on the clip can drop into notches (1d,1e) to create detents for the lever (8) at its two end positions. Pivoting of the switch lever is translated into linear movement by engagement of pin (9) on the lever with the elongated hole (11b) in the plunger actuating plate (11).
