Patent FR-2176701-A1 (FR)
Title: Zone smelting control system - for rod material refining, esp of semiconductors
IPC: G05D27/02
Filed: 1973-02-27
Abstract: The induction coil forming the molten zone in the vertically mounted bar is fed by a rigid water cooled coaxial line from a main tank circuit fed in turn by a flexible coaxial cable from the RF generator. A pick off on the rigid line feeds a digital frequency meter whose output is fed to a comparator with second input in the form of the optimum digital frequency. The error signal controls a servo motor which advances or withdraws the clamp at one end of the bar to vary the cross sectional area of the molten zone, the effective damping on the tuned tank circuit and hence the working frequency. The system is null-seeking.

Title: Video amplifier for colour TV receiver - has dummy G-Y source making three channels identical to increase black level stability
IPC: H04N9/72
Filed: 1976-06-25
Abstract: The video amplifier, for colour TV receiver, has a dummy colour-difference signal source connected to the input side of the third colour channel and behaving in an analogous manner to the R-Y and B-Y sources, connected to the input side of the other two channels. This dummy source ensures that all channels are roughly identical and thereby improves picture quality by making the black level more stable.
