Title: Novel purification of caustic soda
Inventor: FUKUMA YASUNOSHIN
IPC: C01D1/04
Filed: 1985-10-23
Abstract: PURPOSE:To readily high-purity NaOH, by bringing tert-butanol into contact with an aqueous solution of NaOH in a high concentration and heat-treating the resultant clathrate compound under reduced pressure. CONSTITUTION:tert-Butanol is brought into contact with an aqueous solution of NaOH in about 40-60wt% concentration to produce a clathrate compound consisting of the tert-butanol, NaOH and water. The weight ratio of the tert- butanol to the NaOH is about 0.05-0.5. The resultant clathrate compound is then separated from the mother liquor by centrifugal separation, etc. The separated clathrate compound is heated to the melting point of the crystals thereof and heated in a state of solution under reduced pressure to exclude and recover the tert-butanol from the clathrate compound and the aimed concentrated and purified aqueous solution of NaOH is obtained at the same time. The heat energy required for purification can be reduced by this method.

Abstract: PURPOSE:To improve the efficiency of gasification and the efficiency of condensation by a method wherein an inner surface of a metallic pipe is provided with some projections, fins and sub-grooves, the opening width of a main groove between each of the projections is narrowed and formed as a tube part. CONSTITUTION:After on an inner surface of metallic pipe 1 some parallel projections 2 and fins 3 are helically formed at a specified angle in respect to its axial direction, some parallel sub-grooves 5 forming a specified angle are formed on them. Each of the projections 2 is deformed from the center line of the sub-groove 5 toward both sides at a part where each of the projections 2 is crossed with the sub-groove 5. With such an arrangement, the opening width of a main groove 4 between each of the projections 2 is narrowed at a part between each of the sub-grooves 5 so as to form a tubular part 6 having a fine opening. As a result, of the heat transferring tube is used at an evaporating part of a heat exchanger, some air bubbles may easily be formed at an inside part, an evaporation of the thermal medium is promoted and the efficiency of gasification is improved. When the tube is used as a condensing tube, even if the surface of the each of the projections is covered by a thin layer of condensed liquid by a surface tension, each of the fin extremity ends is kept at its exposed state and a heat exchanging efficiency with a thermal medium vapor is kept high, resulting in that a condensing efficiency can also be improved.

Abstract: PURPOSE:To improve a quenching ratio greatly by combining a triangular and a parallelogram prisms, forming a polarization splitting surface of a dielectric multilayered film on the cemented surface of the both, and setting the angle of incidence of incident light on the polarization splitting surface so that the quenching ratio of reflected light is maximum. CONSTITUTION:The prism 10 constituted by cementing the triangular prism 12 which has the dielectric multilayered film on its slanting surface to the parallelogram prism is arranged slanting by an angle beta to an optical axis. The incident light L1 parallel to the optical axis is not perpendicular to an incidence surface 20, but refracted at some angle and incident on the polariza tion splitting surface 16 at an angle alpha. Consequently, a P wave component is transmitted as it is, but an S wave component is reflected as shown by L2, which is reflected by a total reflecting surface 18 facing the polarization splitting surface 16 and projected from a projection surface 22 as projection light L3 in the same direction with the incident light. The angle alpha is adjusted so that the quenching ratio of the reflected light L2 is maximum, and then the P wave component in the projection light L3 is a little, thereby realizing the superior quenching ratio.
