Title: Mains transformer system for CRT appts. - has auxiliary winding designed to eliminate stray magnetic field generated by main windings
Inventor: SCHUBERT RUDOLF DIPL ING
IPC: H04N5/21
Filed: 1977-02-10
Abstract: A picture reproducing appts. includes a picture tube and a mains transformer (2) which generates a stray magnetic field which interferes with the magnetic scanning of the picture tube. To reduce this unwanted effect, the normal winding (4) and core (5) are surrounded by an auxiliary winding (10) which is fed with a compensating current from the mains. The magnitude, phase and waveform of the current (ik) are chosen so that the stray magnetic field from the transformer is substantially eliminated. It is possible to feed this compensating current to the secondary winding of the transformer. Alternatively a special auxiliary winding may be employed. The auxiliary winding may be movable in relation to the core and main windings. The transformer windings may have of the order of 600 turns.

Title: Tufted carpeting space dyeing - has roller with sprung blades to flick dye as droplets against the material
Inventor: SCHOMAKERS HANS
IPC: D06B11/00
Filed: 1977-02-21
Abstract: In applying irregular and mixed colouration to a fabric, esp. floor coverings, the dye is applied in droplet form to a raw white or pre-dyed ground to be fixed by steaming, giving a space dyed effect. The dyestuff is applied by sprung blades which flick the fluid in a spray by holding each blade rigidly at one end while the other free end can be retained against its direction of movement, which places it under tension, to be released and reassert itself. The process ensures that the dyestuff is distributed over the surface, particularly tufted carpetings, without flecking or striping.

Title: Target point recognition in aerial lobe - uses correlator for processed monopulse values, consisting of digital transit time chain with comparators and integrators
Inventor: WEIDLER GERHARD DIPL ING
IPC: G01S13/44
Filed: 1979-01-25
Abstract: The monopulse processor is intended for application in target point recognition which evaluates a signal concerning the target point in the aerial lobe, in addition to the time coded SSR-input signals. The recognition takes place even in garbling situations. The process is carried out in the following steps: the processed monopulse values are fed into a correlator, consisting of a digital transit time chain with comparators and integrators. A reference is formed from two scanning values obtained from a certain given target distance. The reference pulses are compared with information pulses and a tolerance value, and are used for integration of the monopulse values. The correlated values are stored in a memory at the beginning of a frame. The monopulse processing contains derivation of monopulse signals in high and intermediate frequency range, as well as signal processing in the video range.
