IPC: C08F10/00
Filed: 1981-08-06
Abstract: Process for preparing and treating a chromium-containing catalyst so that when the catalyst is activated the risk of explosion is substantially reduced. The catalyst comprises a complex of chromium and optionally other transition metal complexes reacted with one or more organometallic compounds of a metal of group II or III of the periodic table, which metal contains hydrocarbyl groups of 1-20 carbon atoms.

Patent NL-8220328-A (NL)
IPC: H04N5/44
Filed: 1982-08-31
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
