Title: Method for continuous injection of antifoaming agent
Inventor: TANAKA YOSHITSURU
IPC: B01D19/04
Filed: 1983-12-13
Abstract: PURPOSE:To make it possible to inject an antifoaming agent continuously into the respective circulating solutions of an ethylene oxide and gaseous carbon dioxide scrubbers in a production process of the ethylene oxide, by using a diluted solution of the antifoaming agent diluted with an aqueous solution of ethylene glycol adjusted to almost the same specific gravity as that of the antifoaming agent. CONSTITUTION:An aqueous solution of ethylene glycol is prepared by adjusting the specific gravity to almost the same as that of an antifoaming agent to be used, and the antifoaming agent is diluted with the resultant aqueous solution at such a dilution ratio (e.g. about 1,000 times if the amount to be injected is 500ml/day), to give an amount of a liquid for use of a general-purpose small- sized constant rate pump. The resultant diluted solution of the antifoaming agent is then continuously injected into the respective circulating solutions of an ethylene oxide scrubber and a gaseous carbon dioxide scrubber. The above-mentioned diluted solution is capable of keeping the uniform dispersion for a long term and being injected stably thereinto without fluctuating the system of the circulating solutions. Thus, the process is stabilized, and the operation control is facilitated.

Abstract: PURPOSE:To reduce the number of regenerative signals by outputting chroma system signals not simultaneously but serially, independently outputting luminance system signals, and using only two types of video signal lines. CONSTITUTION:The signal line connected to the recording system of a camera 1 has a luminance system input signal line terminal and a chroma system input signal line terminal, luminance system signals (Y+S) are outputted from the image pickup part of the camera 1 to the former terminal, and the signals, which is obtained by time-sequentially arranging chroma system signals (R-Y, B-Y) into a straight line and added with levels so as to discriminate a signal R-Y from a signal B-Y, and so as to obtain the different levels for the both signals, are supplied to the latter terminal. There, since the luminance system signals are discriminated from the chroma system signals in a time-sequentially divided mode out of the regenerative signals, and the chroma system input signals are outputted to the chroma system signal line without being made simultaneous, only the two types of the video signal lines for the chroma system signal and the luminance system signal are sufficient.
