Title: Video signal recording and playback process - automatically playing-back initial section of tape to enter recorded data into memory for display followed by rewinding to start
Inventor: SCHULZ AXEL DIPL ING
IPC: G11B27/34
Filed: 1991-12-17
Abstract: The method involves a magnetic tape video recorder loading a cassette (3) the recorder and drawing the tape out by guide rollers (13,14) across a rotary drum (7) carrying recording/playback heads (13,14). Video output to a screen for display can either be directly during the recording operation or from the playback heads via a detector stage (20) and frame memory (22). Switches (23,25) control the changeover. When the cassette is loaded, the playback mode is automatically engaged for a short period and this allows video information indicating recorded contents to be read and entered into memory for screen display. This is followed by an automatic rewinding to the start position. USE/ADVANTAGE - Displays if tape contains recording prior to operation, preventing possibility of destroying existing recording.
Patent DE-4200784-A1 (DE)
Title: Power-recovery system from air currents - uses horizontal components tangential to inner circle as guides and to generate eddies
Inventor: SCHATZ JUERGEN
IPC: F03D3/00
Filed: 1992-01-11
Abstract: The system recovers power from horizontal and/or vertical air currents, which can flow in alternate directions. Air is stored under wind load in reaction cylinders and transferred to rotary currents. The inflow takes place over similar horizontal components which are mounted tangentially to an inner circle, and which set as guides and generate eddies. The current is guided against the inside wall of the spiral inlet (15) to a current shield (14). The eddies generated are superimposed on the current and receive a rotary impulse. They are wound inside the shield into a potential eddy, and are discharged to atmosphere, inducing flow in the process. USE/ADVANTAGE - Concentrates and converts wind power.

Title: Noise reduction method for video signals - using movement compensation of stored image signals before combining with actual image signal to obtain difference signals
Inventor: DREXLER MICHAEL DIPL ING
IPC: H04N19/80
Filed: 1992-06-27
Abstract: The noise reduction method involves using difference signals (S) obtained from an actual image and a preceding image held in a memory (FSTO), which are fed through a motion-adaptive (MDET) temporal filter (M). The filtered difference signals are combined with the stored image signals to obtain a noise-reduced output signal (O). The stored image signals are subjected to movement compensation (MCO) using the actual image signals before providing the difference signals and combining with the filtered difference signals. The movement compensation can be effected in image signal blocks. ADVANTAGE - Reduced noise reduction only in moving parts of image. Less complicated image detector required.

Title: Apparatus for roller feed tables on sheet-processing machines, such as folding machines, for segregating broadsheets
Inventor: THIEME GUENTHER
IPC: B65H29/62
Filed: 1993-07-31
Abstract: It is characteristic of known apparatuses for segregating broadsheets on sheet-processing machines that the principle of separation and segregation of double sheets is based on suction air, which is susceptible to disturbances in terms of continuous sheet running. Owing to the combination of the pivotable and displaceable mounting of a sheet diverter below the plane of the running sheets, according to the invention, it is possible for said sheet diverter to be pivoted into the plane of the running sheets irrespective of the conveying width set by means of the alignment straight edge, thus allowing complete segregation of blind and double sheets. The causes of the occurrence, in particular, of double sheets as a factor disturbing continuous sheet running are thus ineffective. The apparatus for segregating broadsheets for roller feed tables is preferably used on sheet-processing machines, such as on folding machines. <IMAGE>
