Patent DE-3407180-A1 (DE)
Title: Screw coupling
IPC: B25B23/00
Filed: 1984-02-28
Abstract: The screw coupling serves as an attachment coupling for portable electric drills for driving screws into place. When an adjustable screwdriving depth is reached, the coupling disengages and prevents damage to the screw head and the screwdriving insert. The coupling uses balls as coupling members, the positive locking of which is neutralized by axial displacement of a transmission sleeve. During the axial movement, the balls guided in the transmission sleeve can roll relative to a profiled spindle and an abutment sleeve. The rolling is more advantageous with regard to wear and release force, since high normal forces occur in the known screw couplings with balls.

Title: Device and method for establishing a trip route for finding a trip destination
Inventor: KITTNER HANS-WERNER DIPL ING
IPC: G01C21/34
Filed: 1984-04-10
Abstract: The individual device, consisting of a computer housing, the freely programmable computer section, a keyboard for inputting data, a display for checking these data, a printer and a screen, is equipped with trip route data of individual towns within the direct coverage range of the device or all national destinations (towns) to be acquired. By inputting specific data of the trip destination (town, street name, house number) from a particular location (claims 1-3) into the computer of the device, the device provides a description of the optimum trip route to the destination. The user receives a printout so that unnecessary search and thus the hitherto usual costs are avoided. At the same time, a reduction in frequency of accidents can be expected due to better concentration of the vehicle driver. Corrections can be made for very busy roads by means of a corresponding trip route description and the traffic can be better distributed in others. Detours, building sites, blocked roads and so forth can be taken into consideration very rapidly by inputting new data into the corresponding regional or central devices, thus avoiding traffic jams, lost time and so forth.

Title: Circuit arrangement for the automatic demagnetisation of the tube in a colour-television receiver
Inventor: KRAUS HEINZ DIPL ING
IPC: H04N9/29
Filed: 1984-05-16
Abstract: In the case of a circuit arrangement for the automatic demagnetisation of the tube in a remotely controllable colour-television receiver, in the case of which the operating voltages for the standby mode circuits are picked off from a power supply and those for the television reception mode circuits are picked off from a line transformer of a horizontal deflection circuit which is driven at the line frequency, the power supply network is switched on via a single on/off switch via which at the same time the current for the demagnetisation coil flows, with a PTC thermistor connected upstream. In order to protect the demagnetisation current flow even during the switching on of the standby mode without operating the switch, a bipolar electronic switch is provided in the power supply line of the demagnetisation circuit arrangement, which switch is switched on by line-frequency current pulses.

Title: Method and device for target search and target tracking by means of a beam which can be focussed
Inventor: KRIZ HELMUT DR
IPC: G02B26/08
Filed: 1984-06-15
Abstract: A method and a device for target search and target tracking by means of a beam (1) which can be focussed are intended to permit energy concentration in a small focus spot on the target (2) at a comparatively small cost in terms of equipment and circuitry, which focus spot can be moved in a relatively large spatial region. For this purpose, that deformation of an MDA compensation mirror (9), which is used to compensate for atmospheric propagation disturbances and is based on the alignment of the beam (1) to the target (2) and the matching of the focus spot to the target distance, is undertaken by a platform (4) for beam pivoting and by telescope optics (10) for setting the focal length, so that the deformation dynamics of the mirror surface (8) are available for atmospheric compensation, and possibly for fine direction finding, with respect to focal length and beam direction. The drive for the platform (4) and the telescope optics (10) is derived from the instantaneous mean curvature and curvature direction of the deformable mirror surface (8), which, for their part, can be determined via the control variables (Ui) of piezo-actuating elements (18i).

Title: Paper with a screen print
Inventor: CARLSEN GUNNAR
IPC: G07D7/00
Filed: 1984-06-30
Abstract: In photocopies of confidential computer lists, it is to be recognisable that they have been copied from an original which was not allowed to be copied. For this purpose, there is provided on the original a screen print which consists of two screen patterns of the same scope of tone value which cannot be distinguished from one another by the human eye. One of these screen patterns forms a basic pattern while a coarser screen pattern forms a warning text inserted in the basic pattern, e.g. PIRATE COPY. During photocopying, the screen dots of the basic screen are not recorded so that this basic pattern is copied so as to correspond to a uniformly inked surface. In contrast, the screen dots of the coarser screen pattern are copied, thus resulting in the warning text becoming visible on the copy.

Title: Regenerative brake for a DC traction motor
Inventor: BERTLING TONI DIPL PHYS DR
IPC: B60L7/12
Filed: 1984-07-30
Abstract: In a regenerative brake for a DC traction motor (1, 2), the armature (1), a reactor (3), a network thyristor controller (4) and a parallel circuit consisting of a capacitor (5) and a deactivable thryistor controller (6) can be connected in series to the network (N). The series circuit formed from armature (1) and reactor (3) can be by-passed by means of an armature thyristor controller (7) in such a way that when the armature thyristor controller is conductive the armature circuit is short-circuited and the reactor (3) is magnetically charged and, when the armature thyristor controller is disabled, is connected via the network thyristor controller (4) and the capacitor (5) and the energy stored in the reactor (3) is transmitted to the network (N). A control device for the motor voltage is provided by changing the exciter current, which device is fed a signal which is proportional to the armature current (Ja), a signal which is proportional to the speed (n) of the traction motor, a signal which is proportional to the voltage (U1) upstream of the capacitor (5), a signal which is proportional to the voltage (Un) downstream of the capacitor (5) and a signal which is proportional to the speed (n) of the traction motor. In the upper motor speed range in which the motor voltage produced is greater than or the same as the network voltage, the armature current thyristor controller (7) and the network thyristor controller (4) are alternately opened and closed in opposite directions. In this process, the entire kinetic energy of the vehicle can be fed back into the network largely without loss. <IMAGE>

Title: Electromagnetic instrument for determining the flow speed of electrically conductive substances, using a semiconductor preamplifier with an upstream-connected input transformer
Inventor: SCHMIDT HARTMUT DIPL PHYS
IPC: G01P5/08
Filed: 1984-08-25
Abstract: A flow meter using the electromagnetic method, in which the effective input noise impedance of the measurement amplifier is reduced by means of a transformer. In the case of electrically highly conductive fluids, this results in a considerable improvement in the product from the required magnetic field strength (and hence the required auxiliary energy), time resolution and the lower measurement limit which can be reached. In order to keep interference in the transformers low, they can be constructed as annular-core transformers and can be accommodated in a screened housing. In order to simplify the handling of the transformers, the magnetic alternating field can be given a sinusoidal response with time in order to produce the measurement voltage, and the measurement amplifier can be provided with band limiting (for example a harmonic filter). Further optimisation of the totality of the above-mentioned properties can be achieved by adding a low-pass filter having a flow-speed-dependent limiting frequency to the sensor output (increasing the limiting frequency with increase in flow speed).

Title: Temperature sensor system for domestic refrigerators
Inventor: SPORBERT THOMAS
IPC: G05D23/27
Filed: 1985-03-15
Abstract: The invention relates to a temperature sensor system for domestic refrigerators for detecting, monitoring and recording the temperatures of stored goods and the interior. The aim of the invention consists in producing a novel sensor system which meets the requirements of an accurate, reliable and economic regulation. In particular freezing and storing frozen is to be simplified and made problem-free for the operator. Moreover, advantageous applications also arise in the higher temperature range.   The features of the invention consist in that only one temperature sensor system is arranged as a combination in freezing compartments or refrigerating spaces. This combination can be arranged independently of constructional and technological conditions in such a manner that the parameters in terms of regulation can be satisfied.   The use of infra-red radiation for obtaining a temperature signal is essential.
Patent DE-3513079-A1 (DE)
Title: Method and device for battery heating
Inventor: JOSEFOWITZ WILLI DIPL ING
IPC: H01M10/50
Filed: 1985-04-12
Abstract: A method is described for maintaining a temperature (which ensures a minimum capacity) of the electrolyte of a battery, especially for vehicle drives, which is connected to an electrical network during phases where it is not in use, via a charger, for charging and recharging. In order to reduce the construction and apparatus cost for battery heating, the charger is intended to be used for heating in that, if the temperature of the electrolyte falls below a first predetermined value, the charger is connected in order to initiate a renewed recharging process, which causes the temperature of the electrolyte to increase until a second, higher temperature is reached. A device for carrying out this method envisages a temperature sensor which detects the temperature in the electrolyte of the battery, the charger being connected for renewed recharging as a function of the measurements of said temperature sensor.
