Title: Process for separating organic acid out of liquid containing organic acid
Inventor: MAEDA TOSHIHIRO
IPC: B01D15/00
Filed: 1990-11-02
Abstract: PURPOSE:To separate organic acid efficiently by bringing organic acid-containing liquid into contact with cation exchange resin in the state of retaining pH of organic acid-containing liquid lower than pKa when the ionization constant of organic acid is set at Ka. CONSTITUTION:Organic acid such as liquid prepared by the fermentation process is brought into contact with cation exchange resin, and the organic acid is adsorbed into the cation exchange resin, then said cation exchange resin is brought into contact with elute (example: dilute sulfuric acid) to desorb the organic acid and the liquid containing the organic acid is separated out of the elute. At this time, the organic acid-containing liquid is brought into contact with cation exchange resin in the state of retaining pH of the organic acid liquid lower than pKa when the ionization constant (in the case of polybasic acid, the first ionization constant) of the organic acid is set at Ka. As a result, the organic acid can be separated efficiently out of a water solution containing the organic acid-containing liquid, for example, the organic acid prepared by the fermentation process and also containing sugar, inorganic salt, coloring component and the like.

Title: Heater
Inventor: GATES WILLIAM GEORGE
IPC: H05B3/36
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a heater for heating a sealed vessel, mounted on the outside by clamping a metal foil heating element buried in a dielectric sheet to a surface to be heated by a leaf spring which is curved when released. SOLUTION: A leaf spring 20 has a stepped part on the end part far from the notch, whereby a shoulder part 32 and a projection part 34 protruded therefrom are formed. The stepped part has substantially the same dimension as the total thickness of a heating element 4 and an aluminum sheet. When the projection part 34 is fastened to a sealed vessel 2 by a screw 36, the leaf spring 20 clamps the heating element 4 to the inner surface 18 of the sealed vessel 2 with an uniform load. Thus, by forming shoulder parts 16, 32, the excessive fastening of the leaf spring 20 in relation to the end part of the heating element 4 can be surely prevented. Further, a recessed projection part 38 functioning as a cable clamp is formed on the leaf spring 20. Accordingly, a heater can be miniaturized, and the sealed vessel can be thus kept in a small size.
