Title: Production of radiation-resistant polymer composition
Inventor: FUJIMURA SHUNICHI
IPC: C08F291/00
Filed: 1986-02-10
Abstract: PURPOSE:To obtain a polymer composition having excellent radiation resistance and freed of blooming of additives, by adding a coumarone/indene oligomer to a polymeric material and subjecting the mixture to treatment for generating free radicals. CONSTITUTION:A coumarone/indene oligomer obtained by copolymerizing a coumarone with an indene is added to a polymeric material. This mixture is subjected to treatment for generating free radicals to polymerize the coumarone-indene oligomer in the polymeric material. The amount of the coumarone/indene oligomer added to the polymeric material is preferably at least 5pts. per 100pts.wt. polymeric material in order to impart higher radiation resistance to the produced composition. Examples of means for subjecting the mixture to treatment for generating free radicals after said materials are kneaded include heating of the mixture after adding an organic peroxide thereto and irradiation of the mixture with an ionizing radiation such as beta-rays, gamma-rays or electron beams.

Title: Pressure equalizing and exhausting method for blast furnace
Inventor: KOBUKA SADAO
IPC: C21B7/18
Filed: 1979-03-06
Abstract: PURPOSE: To reduce the quantity of gas for secondary pressure equalizing used, and to improve the efficiency of the recovery of furnace gas, by a method wherein at least one among septum valves for controlling top pressure is provided with functions as a septum valve for primary pressure equalizing and exhausting in an upper pressure equalizing chamber.  
     CONSTITUTION: When primarily equalizing the pressure of an upper pressure equalizing chamber 3, a primary pressure equalizing valve 13 is first opened, and half clarified gas from a Venturi scrubber 9 is let pass through a gas passage 10 4  for primary pressure equalizing of a valve body 10, let flow through a primary pressure equalizing pipe 12 and introduced to the chamber 3 through the valve 13 and a cyclone 14. Since both the static pressure and dynamic pressure of the half clarified gas work against an intake port 10 6  at that time, the half clarified gas corresponding to full partial pressure equalizes the pressure of the chamber 3. Thus, pressure in the chamber 3 becomes higher as compared to the conventional methods, and the quantity of clarified gas required for secondary pressure equalizing can be reduced. When exhausting pressure, meanwhile, the gas in the chamber 3 can be recovered in a short time by low pressure generated at the downstream side of the septum valve 10 by opening a pressure exhausting valve 16 mounted to a pressure exhausting pipe 15.
