Title: Flow amount meter
Inventor: SAKIYAMA HIROTO
IPC: G01F23/66
Filed: 1988-04-04
Abstract: PURPOSE:To allows a flow amount meter to move up and down following an increase or decrease in the amount of liquid without any lever type float by forming an indication rod to be dipped in the liquid by using a material which is close in specific gravity to the liquid. CONSTITUTION:When the liquid 1 in a tank 7 increases or decreases in amount, buoyancy operating on the indication rod 2 varies and the weight of the indication rod 2 also varies, so the indication rod 2 is pressed up by a spring 3 or moves down by its own weight. The up-down movement of the indication rod 2 causes a liquid amount indication body 4 fitted to the upper end of the indication rod 2 to move up and down, thereby indicating the amount of the liquid according to which position on a liquid amount scale 9 displayed on a transparent cover 8 the top surface 4a of the liquid amount indication body 4 indicates. Said indication rod 2 itself is formed of the material whose specific gravity is close to that of the liquid 1, so the indication body follows up the increase and decrease in the amount of the liquid 1 without nay lever type float and the structure is simplified.

Title: Method for racemizing optically active serine
Inventor: KITAGAWA SADAO
IPC: C07C227/18
Filed: 1984-04-26
Abstract: PURPOSE:To suppress the decomposition of optically active serine and obtain a racemic modification in high racemization ratio and yield, by heating an aqueous solution of the optically active serine at a specific temperature within a specific range under a higher pressure than the vapor pressure of the above-mentioned aqueous solution. CONSTITUTION:An aqueous solution of optically active serine is pressurized under a higher pressure than the vapor pressure of the above-mentioned aqueous solution, preferably >=1kg/cm<2> higher than the above-mentioned vapor pressure and heated at 150-350 deg.C to racemize the optically active serine. In case the serine is synthesized by a chemical synthetic method, the DL isomer is usually obtained and optically resolved to give the desired obtical isomer, but unnecessary anitpodes are racemized and further optically resolved for use. The racemization by heating is economical, but there is a problem in stability of the optical isomers. The pressurizing and heating of the optical isomers in the state of the aqueous solution permit the high racemization ratio, and the decomposition of the optical isomers is remarkably reduced.
