Title: Recovery of pyrimidine
Inventor: KAWAI HARUYUKI
IPC: C02F1/04
Filed: 1978-04-26
Abstract: PURPOSE: To recover pyrimidine useful as an intermediate for the synthesis of drugs as an azeotripic mixture with water in a high concentration, by distilling an aqueous effluent containing a small amount of pyrimidine discharged from a process of preparing acrylonitrile from propylene.  
     CONSTITUTION: An aqueous solution containing 5000 ppm or less of pyrimidine is distilled to recover a cut boiling at 98W99°C under normal pressure as an azeotropic mixture with water, thus giving pyrimidine in a high concentration. An aqueous effluent from gas phase catalytic oxidation of propylene with ammonia may be cited as the aqueous solution. To prevent the pyrimidine loss, the cut boiling at 90W 99.8°C is collected, and, if necessary, distilled. Pyrimidine is obtained with a high concentration by separating an aqueous solution containing 1.5% or more of pyrimidine with a solid alkali metal hydroxide to separate into two layers, from which the upper layer is separated.

Title: Gas-blast circuit breaker
Inventor: HASHIMOTO TAKESHI
IPC: H01H33/70
Filed: 1990-03-02
Abstract: PURPOSE:To improve dielectric strength of a gas-blast circuit breaker by forming specified gas flow passages other than a throat of a nozzle in the outside-diameter portion of the throat of the nozzle that blows arc-extinguishing gas upon an arc generated between a stationary arc contact and a movable arc contact. CONSTITUTION:Insulating gas compressed by a cylinder 4 and a piston 5 is led to a nozzle 1 made of an insulator, and then blown upon an arc generated between a movable contact 6 and a stationary arc contact 2. The nozzle 1 has holes 9 which communicates the downstream side 8 of the nozzle with the upstream side 11 thereof formed in the peripheral portion of a nozzle throat 10. Each of the holes 9 is formed such that a difference between a cross-sectional area (s) made by the flow of gas through the hole 9 in the process of breaking a circuit and the cross-sectional area (S) of the stationary arc contact is not less than the cross-sectional area of the nozzle throat 10 and not more than twice thereof. This constitution can prevent the phenomenon of transiently lowering the pressure of gas at the head of the stationary arc contact, which is presented immediately after the head of the stationary arc contact goes out of the nozzle throat 10, and also can heighten the pressure of gas at the head of the stationary arc contact in a wide range of the circuit-breaking process.

Abstract: PURPOSE:To obtain reinforcing parts of a type having resistance to its elastic deformation by a method wherein the types on one or more specific sections of a plurality of type sections are made up of a plurality of type side walls of different inclination angles. CONSTITUTION:A type wheel consists of rectangular type sections at 14 places arranged in a circular form and is made of an elastic material, each type section is provided on its inner surface with a hammer impact part subjected to hammer striking and a constricted part is formed on the inside of a connection between each adjacent type section. With respect to the type part 51a of 7, for example, the upper area 51s has a large unit contact area and the lower area 51, has a small unit contact area. With respect to a type section 51, therefore, the type side walls SW1 and SW2 of the upper and lower areas 51S and 51T are given different inclination angles alpha and beta, respectively, although they are formed on the same type. Since the lower area 51T of the type is spread toward its base, even if the contact density of printing area is low, the side wall SW2 having a large inclination angle brings about an increased reinforcing effect.
