Patent DE-3020080-A1 (DE)
Title: Thermoelectric printing device esp. typewriter - has laser light source projecting onto charged ribbon which is electrostatically pulled towards paper
Inventor: SCHMITT JUERGEN DIPL PHYS
IPC: B41J2/465
Filed: 1980-05-27
Abstract: A thermoelectric printing device for producing symbols on a recording sheet, typically ordinary typing paper, uses a colour carrying strip (typewriter ribbon) composed of a coloured layer and support strip, this ribbon contains a dielectric which can be permanently polarised by a charging device; the light source used for projecting a beam through a template onto this ribbon is a laser diode. The source softens the coloured layer (ink) on the ribbon, while simultaneously or just afterwards a temporarily energised electrode pulls the ribbon, due to its charge, onto the paper. This arrangement operates noiselessly and, due to the use of a laser as light source, does not require any shielding from ordinary light. The dielectric may comprise either a thermoplastic, dielectric, permanently polarisable material such as carnauba wax in the ink layer, or polyethylene terephthalate in the support ribbon.

Title: Rotating shutter in TV camera - has driving motor synchronised by frame and line pulses achieving sharp, slow motion replay
Inventor: FRITZSCHE WILFRIED PROF DR ING
IPC: H04N5/235
Filed: 1980-06-18
Abstract: TV slow motion action replays are blurred because the camera exposure time of 20ms is too long for fast moving objects. An exposure of a few ms. is achieved by placing a shutter (2), rotating at 50 rps, in the optical path. An aperture (7) gives the required exposure at the start of each half frame. The driving motor (12) is synchronised by comparing (6) frame (Vsoll) and line (Hsoll) synch pulses with pulses (Vist, Hist) derived respectively (14,15) from a single hole in the shutter and 125 slits round its circumference. Variable exposure from 10 to less than 1ms is achieved by using two driving motors and two shutters, each with 180 degree apertures, and controlling their relative phase.

Title: Forming tool connecting contact lugs to flexible cable - is shaped to ensure smooth roll-in of contact tongues without overlap
Inventor: KORTH JUERGEN PETER
IPC: H01R43/058
Filed: 1980-08-01
Abstract: The upper forming tools, situated behind one another during operation, have arched recesses running in so-called guide surfaces formed to ensure a clean roll-in of the contact tongues when fixing the cable end to the terminal lug. The guide surfaces are so contoured at the centre axes of the tools that neither overlap of the contact tongues in the insulated region nor overlap of the tongues in the non-insulated region of the cable can occur. Due to the finished shape of both arched recesses in the tools, both sets of contact tongues on the ready-to-crimp terminal element, roll-in simulaneously, and are formed symmetrically over the cable insulation and conductor respectively. This gives a clean, neat and reliable electrical connection between contact terminal and conductor without the need for soldering.

Title: A=D measured value conversion with limit value comparison - using control logic, whose supplied or generated clock pulse feeds last digital measured value into memory
Inventor: HEINRICH WINFRIED DIPL ING
IPC: H03M1/60
Filed: 1980-09-05
Abstract: The measured value is represented by an analog voltage and is converted into a proportional frequency by a voltage-frequency converter, the frequency pulse being controlled by a logic. They are processed in a two-way counter, transfered to a memory and digitally displayed. The control logic receiver, or generator, a clock pulse for transmission of the last digital measured value to the memory. It also sets the counter and a sign generating flip-flop to a starting value, and controls the voltage-frequency converter operation. A zero test circuit transmits a pulse, when a zero counter state appears at negative starting value, for the counter switching. The measured value conversion is terminated by the control logic after a preset time interval. The digital measured value, accepted by the memory after conversion, is supplied to the digital display via a seven-segment decoder. The stored, digital measured value is compared by two identical comparators with two digital limit values.

Title: Toy flying object (kite)
Inventor: GROENING RUEDIGER DR
IPC: A63H27/08
Filed: 1981-10-09
Abstract: The invention with the designation "toy flying object (kite)" relates to a novel design principle for kites. Previously described kites often have stabilisation problems in respect of their smooth flight depending on slight differences in their wing symmetry and depending on the wind force. This disadvantage is removed by the present invention in that the wing of the kite consists of an axially rotating wind wheel which is rotated by the wind during the flight. An example of the flying object according to the invention is indicated in the drawing (wing (1), axis of rotation (2), wooden bar (3), pull cord (4), stabilising wind wheel (5)). Due to the rotary movement of the wing, a high stabilisation effect is caused, such as is also produced in spinning tops. A main possibility of use of the invention will probably be as a toy. <IMAGE>

Title: Device for measuring sequences of movement of reflecting measurement points
Inventor: THEYSOHN HELMUTH DR MED
IPC: G01S7/487
Filed: 1981-10-24
Abstract: On a device for measuring sequences of movement of reflecting measurement points, which are attached, in particular, to a person or an animal, having one or more (at least two for three-dimensional measurements) moving signal transmitters, several reflecting measurement points, per signal transmitter one device each for capturing the reflected signals, the object is to be achieved to obtain a high accuracy of measurement at a high measuring frequency, and to create the possibility of on-line transfer of the measurement values to an EDP system. This object is achieved by the fact that the signal transmitter sends out radiation of a particular geometric figure which is of such a nature that a sequence of more than two radiation pulses falls onto each reflector, that a device is used as pick up of reflected signals which does not pick up the geometric position but only the start of radiation pulses in time and converts them into one electrical pulse each and that a device is provided which determines the time between the arrival of the first radiation pulse at a reference point and the first electrical pulse of each pulse sequence and the time intervals between the electrical pulses of a pulse sequence with respect to one another.
