Title: Tape speed regulator for video recorder playback - has selection unit to allow changeover to non-standard speed set by potentiometer
Inventor: LAURENTIUS WERNER DIPL ING
IPC: G11B15/467
Filed: 1993-03-18
Abstract: A magnetic video tape (1) recording is played back using a helical scan unit (30), the tape being driven by a roller (2) coupled to a motor (3) and with a contact roller (4). A control head (9) generates pulses from control tracks on the tape and these are phase compared (12) with reference signals (13). The comparator provides a regulating input via a selector switch (14) to close the loop and maintain the standard speed. If a special playback condition is required, the tape speed can be set by a potentiometer (32) and can be gated (21) through the selector (14) to the motor. A coupling element (15) allows the speed to be related proportionally to the standard speed. USE - Provides variable speed playback.

Title: Method and means for testing recording carriers
Inventor: BRAUCH ULRICH DIPL ING
IPC: G11B27/36
Filed: 1993-04-10
Abstract: In a method for testing recording carriers on which there are recorded signals which contain not only useful information but also variables which are independent of the useful information but are required for recording and reproduction, variables independent of the useful information are measured and compared with limit values when reproducing the recorded signals. Error messages are issued if fixed deviations occur. In the case of a means for carrying out the method, a plurality of reproducing devices are each connected via an interface to a bus system, to which an evaluating circuit and a computer are also connected. The interfaces and the bus system are designed for the selective transfer of reproduced signals from the reproduction devices to the evaluating circuit and for the transfer of data between the computer and the reproducing devices. The evaluating circuit receives the reproduced signals of in each case one reproducing device and evaluates the variables which are independent of the useful information.

Patent DE-4320625-A1 (DE)
Title: Swing rotor
Inventor: BACH EBERHARD
IPC: B64C39/04
Filed: 1993-06-22
Abstract: The invention relates to a drive for "airborne vehicles which move in a floating manner on an air cushion on the ground or fly in the air like an aircraft" (German Patent Office Application dated 26 May 1992, File Reference: P 4217374.4), also called "Aerodynamic multipurpose apparatuses" (AMA). The drive is largely matched to the aerodynamic features of the AMA. The invention can be used as a drive in airborne vehicles which fly slowly. The swing rotor operates on the principle of an impeller, whereby according to the invention the rotor blades (swinging surfaces) are not rigidly attached but are mounted on the periphery of two wheels (which rotate in a parallel manner about an axis) such they can pivot about their transverse axes. During the rotational movement of the swing rotor in the airflow of the wind of motion, the incident angle of the swinging elements is intended to be controlled as a function of the rotation angle, the air speed and the thrust vector control such that an impulse is produced in the direction of the required thrust vector, as far as possible at every rotation angle. This ensures the aerodynamic effectiveness of the drive and makes it possible to control the direction of the thrust vector within the limits required for AMA. <IMAGE>

Title: Method and device for transmitting information from space
Inventor: IGLSEDER HEINRICH DR ING
IPC: B64G1/66
Filed: 1993-07-29
Abstract: It has not hitherto been possible in practice to transmit information from space, since a device (28) has to be transported in each case into space for the information concerned. In the device (28) according to the invention, it is provided for a plurality of reflectors (10) to be arranged in distributed fashion in the form of a grid on a supporting framework (11). Reflectors (10) selected therefrom according to the information to be transmitted are moved into a position in which they reflect light beams emitted by the sun to the earth (26). The respective information is made visible to the observer on the earth (26) in that the selected reflectors (10) produce an array of points of light corresponding to the information to be transmitted. Conversely, the reflectors (10) which are not required to represent the respective information are positioned in relation to the sun in such a way that these reflectors (10) are not visible to the observer on the earth (26) as points of light. In this way, the invention enables all kinds of different information to be transmitted to any information areas (29) on the earth using one and the same device (28). The invention is particularly suitable for transmitting advertising from space to the earth (26). <IMAGE>

Title: Electrical power controller
Inventor: BUCHWEITZ KNUT DIPL ING DR
IPC: G05D23/20
Filed: 1993-10-29
Abstract: A circuit arrangement for specifying a power occurring at non-reactive resistors (25, 29, 33, 36, 39) and methods for operating the circuit arrangement are proposed. The circuit arrangement according to the invention is preferably used in electrical heating devices, in particular in flow-type heaters (through-flow heaters, continuous-flow heaters). The circuit arrangement contains at least two resistors (25, 29, 33) which can be connected in series. The connections (27, 30) of one resistor (29) can be switched via switching elements (TR2, TR3) to the same power supply line (L2). The bridging of the resistor (29) permits the use of mechanically stable resistors (25, 29, 33) without having to consider their heating power (heat output), which may be higher than a predetermined maximum switching capacity applied to the power supply network (L1, L2, L3). The methods according to the invention for operating the circuit arrangement permit the continuous provision of power by means of specific selection of series circuits of the resistors (25, 29, 33) and selection of individual resistors (25, 33), if appropriate in the context of clocked operation, using control signals (18-23) which are particularly simple to generate. <IMAGE>
