Title: Universal video data playback background of the invention
Inventor: PULLEN ALAN J
IPC: G11B3/00
Filed: 1983-02-21
Granted: 1989-03-07
Abstract: This method allows optical disc to be played on either NTSC or PAL system.  The recording method involves providing encoded digital data as video level signals and also providing a series of pulses at the horizontal line repetition rate of a first video format.  The pulses and digital signals are combined to form a composite signal such that the segments alternate with the pulses in time.  The recovering method comprises playing the disc on a predetermined format video disc player to recover the recorded signals.  The separated pulse signals are synthesised to obtain vertical pulse signals having a repetition rate equal to that of vertical syncronous pulses relative to horizontal pulses in the predetermined format.  The vertical sync. signals are fed to the player circuitry.

Hydrogenating acetylene compound to  cis-  olefin in high selectivity is provessed without  separation  of  produced catalyst under hydrogen 1 atm at 25 deg.C.
