Title: Timing error correction in replay of video tape signals - employs start-stop oscillator switched by colour synchronising signal
Inventor: BLEES GERHARD
IPC: H04N9/87
Filed: 1980-04-03
Abstract: The video tape replay unit is used to improve the compensation of rapidly varying timing errors. These can occur in tape recordings and cannot be satisfactorily eliminated by the existing voltage controlled oscillator compensation system. From the multitrack tape the signals are separated into light intensity and colour type channels. The demodulation of the latter signal employs a colour carrier which is reset, every line, to the phase position of the colour synchronising signal as retrieved by the tape reading head. The reset signal is in effect carried by the start-stop oscillator signal which is switched on by the colour synchronising signal and turns off at the end of each line. It can thus closely follow any time variation in synchronising signal.

Patent DE-3100233-A1 (DE)
Title: Antigravity gyroscope
Inventor: BERNECKER STEFAN
IPC: F03G3/08
Filed: 1981-01-07
Abstract: The aim of the invention is the direct conversion of flow into lift in an entirely closed system. The main possible applications are in aviation and space flight. This problem is solved by discovery of the physical fact that for each elementary part of a body possessing volume the gravitation acts on this elementary part absolutely perpendicular to the centre of the earth, but that as a result the gravitational forces acting on the totality of parts of a body do not run parallel, since they intersect at one and the same point M and thereby stand at a certain (effective) angle @ to one another (@ drawing). An extremely rapidly rotating ring or disc would attain weightlessness from a circumferential speed of 12.4 km/sec (considering the peripherally rotating effective mass). With further acceleration in excess of 12.4 km/sec calculable lift is possible solely due to rotating masses. <IMAGE>
