Title: Television signal processing circuit
Inventor: ACHIHA MASAHIKO
IPC: H04N7/01
Filed: 1986-08-29
Granted: 1990-01-09
Abstract: Abstract A television signal processing circuit separates a television signal into a luminance signal and a chrominance signal, or interpolates the scanning lines of the television signal by using a video memory, such as a frame memory or a field memory. The circuit determines whether the television signal to be treated is standard or non-standard. Depending upon this determination, the circuit changes its operational mode so that it operates properly even when the television signal is different from a standard television signal and contains jitter in the time axis, as does a signal from a VTR. When the television signal is thus non-standard, the processing circuit operates without the video memory.

Abstract: ABSTRACT OF THE DISCLOSURE         Hitherto processes proposed in recent years for preparing esters of phenol sulphonate salts by reaction between a carboxylic acid chloride and a phenol sulphonate salt place considerable emphasis upon dehydrating the reactants before they are brought into contact in an organic solvent reaction medium.  The present invention avoids the problems of employing non-aqueous solvents by carrying out the reaction under aqueous conditions but with controlled alkalinity and water content, especially at a base to phenol sulphonate mole ratio of from 1.3:1 to 1.6:1 and a total water to phenol sulphonate (as the anhydrous material) of not more than 4.5:1.  The reaction advantageously employs in preference only a small molar excess of carboxylic acid chloride over the phenol sulphonate and preferably has a reaction temperature controlled to below 30°C, especially 5 to 20°C.  In a further improvement to the process, the difficulty of enhanced contamination with benzoic acid in the products can be ameliorated by employing a small but effective amount of a surfactant, especially an alcohol ethoxylate, in the reaction mixture.  The process is especially well suited to making sodium benzoyl oxybenzene sulphonate from sodium phenol sulphonate dihydrate and benzoyl chloride.
