Title: Electronically controlled pivoting device for cameras
Inventor: GAENG LUTZ-ACHIM DIPL-ING
IPC: G03B17/56
Filed: 1981-12-08
Abstract: A pivoting device is described for video cameras, film cameras and still cameras, which allows exposures to be made without any blurring due to movement. This is achieved principally in such a way that the camera is pivoted stepwise, that is in such a manner that the rotary movements always occur when the shutter has been closed, whereas the exposures are only carried out when the camera is momentarily stationary. The principle described can be expediently realised by three methods:   a) A pulse, synchronised with the image, from the camera is used to control the stepper motor-operated pivoting device. This design allows pivoted exposures to be made in real time. b) A sensor on the camera or on the pivoting device determines when the camera is stationary and triggers a single frame and then the next angle step. This design is mechanically simpler to construct. c) The control triggers an angle step and, after a certain time delay for mechanical settling of the system, a single frame of the camera. This highly simple design is only suitable for time-lapse exposures.

Patent DE-3208449-A1 (DE)
Title: Driver circuit for a transistor
Inventor: KUROKI KAZUO
IPC: H02M7/48
Filed: 1982-03-09
Abstract: In the driver circuit according to the invention, a pulse sequence (A2) for switching on a transistor (TR2) is transmitted potential-isolated via a switching-on pulse transformer (T1). One terminal of a secondary winding of the switching-on pulse transformer (T1) is connected directly to the emitter of the transistor (TR2) and the second terminal of the secondary winding is connected via two separate current paths (D3; R1, C, D2) to the base of the transistor (TR2). As long as a ''1'' signal is present on the secondary winding of the switching-on pulse transformer (T1), this signal directly generates a base current for the transistor (TR2) via the first circuit branch with the diode (D3). At the same time, a capacitor (C) in the second circuit branch is charged up. This capacitor takes over the base current for driving the transistor (TR2) during the pulse intervals of the switching-on pulse sequence (A2). This results in a static drive of the transistor (TR2), using only one switching-on pulse transformer (T1). <IMAGE>

Patent DE-3214095-A1 (DE)
Title: Hazard warning system with travel direction change indicator
Inventor: CEVELA VACLAV DIPL ING
IPC: B60Q1/50
Filed: 1982-04-16
Abstract: If a defective car has to drive at a reduced speed or a car is being towed by another car, the hazard warning system must be switched on on all the vehicles since this is an obstacle for other car drivers. Then, if these vehicles have to turn off to the right or left it is necessary for safety reasons to display the travel direction change indicator. This is only possible if the hazard warning system is previously switched off and, because the vehicle is being towed, switched on again after the turn. All this is an additional strain for the drivers. The object of the invention is to substantially increase the safety of the driving during the turning process whilst avoiding the previously described disadvantages by means of the possibility of directly switching over from the hazard warning system to the travel direction change indicator and vice versa without having to switch off the hazard warning system. The change-over of the voltage from the hazard warning signal generator to the flasher or pulse generator and vice versa takes place by means of a relay or an electronic component, such as, for example, transistor switching stages, ICS, thyristors and the like, which function in a comparatively similar manner. <IMAGE>

Patent DE-3230561-A1 (DE)
Title: Circuit for controlling electrical drives whose rotation direction can be reversed
Inventor: DIETRICH BERNHARD ING GRAD
IPC: H02P1/40
Filed: 1982-08-17
Abstract: A circuit for controlling electrical DC or AC drives whose rotation direction can be reversed consists of an electromagnetic switching apparatus for operating contacts which are located in the main circuit, of which two contact pairs are connected as a changeover switch for polarity reversal, and of two coils which are located in a control circuit and whose energising is switched via control contacts which determine the rotation direction of the drive. While, in the past, such a switching apparatus has comprised two so-called reversing contactors, which had to be mutually interlocked, one contactor can be saved if a common contact actuator is provided for the moving contacts of at least the two contact pairs required for reversing the rotation direction, which contact actuator is connected to an armature which is located in the magnetic circuit of both coils, has a central quiescent position and can be moved by the one coil into the one limit position and by the other coil into the other limit position. A further possibility is once again to provide a common contact actuator for the moving contacts, which is connected to an armature which is located in a magnetic circuit which is common to both coils and is premagnetised by means of a permanent magnet. In this case, magnetomotive forces are produced in the same sense in the one direction in order to reach the one limit position of the armature, magnetomotive forces are produced in the same sense in the opposite direction in order to reach the other limit position, and magnetomotive forces which are in each case of equal magnitude but are in opposite directions are produced in order to reach the central position.

Patent DE-3308055-A1 (DE)
Title: Code lock for safes or the like
IPC: E05B37/16
Filed: 1983-03-08
Abstract: The code lock has a locking mechanism with the following essential parts: a drive plate (23), a rocker (24), a blocking tab (27) and a serrated plate (18). During the rotation of a bolt knob (21), the drive plate (23) is both moved in the longitudinal direction of the push bolt (19) and pivoted relative to the rocker (24). This is brought about by an axle and driving pin (25) which connects the drive plate (23), rocker (24), and push bolt (19). The pivoting movement takes place counter to the effect of a leg spring (29), and the rocker (24) bears against the blocking tab (27) which is pivotable in the serrated plate (18). When all the blocking strips are located between the legs of the serrated plate, the latter can be lifted, and the rocker (24) and push bolt (19) can pass. After the rocker (19) has passed, the serrated plate (18) returns to its initial position. This occurs when the code lock is half-opened. When the code lock is between half-opened and completely open, the push bolt (19) can be moved without any adjustment of the coding. <IMAGE>
