摘要： PURPOSE:To prevent the generation of electrolyte mists in the stage of decontaminating the metallic parts contaminated with radioactive materials by electrolytic polishing by providing an air permeable defoaming layer consisting of a specific material on the surface of the electrolyte in an electrolytic cell. CONSTITUTION:Metallic parts 3 contaminated with radioactive materials are immersed in the electrolyte 2 in an electrolytic cell 1, and voltage is impressed between said parts and an electrode 5 to remove the contaminating materials on the surfaces of the parts 3 by electrolytic polishing. Electrolyte mists are generated by the gases consisting essentially of oxygen and hydrogen generated from both electrodes 3, 5 in this stage, and scatter from the surface of the electrolyte to pollute the working environment and to corrode the device. In order to prevent the generation of such mists, an air permeable defoaming layer 7 constituted of wire-net-like or floatable granular materials made of a material having high corrosion resistance such as ''Teflon '', PVC, PE or the like is placed on the surface of the electrolyte 2. The generation of the electrolyte mists is suppressed by the layer 7.

摘要： PURPOSE:To maintain the components of separated gases by packing adhesives in both end parts of a defective separating membrane tube, and allowing the adhesives to set thereby closing the tube if there is said defective tube in a holllow membrane separating module. CONSTITUTION:If there is a clogged part 9 in one of separating membrane tubes 2, a terminal member 5 in one end part of a body 1 is first removed, and an uncured adhesive 10 is coated on the end face of a terminal sealing part 3 and is packed down to the prescribed depth of the tubes 2. Next, a gas of prescribed pressure is supplied into the tubes 2 through the nozzle 6 of the member 5 to extrude and remove the uncured adhesive 10 from the inside of the tubes 2, but in the tube 2 having the part 9, the adhesive is left as it is and the adhesive 10 left therein is allowed to set. In the other end of the body 1 as well, the similar treatment is carried out to close both end parts of the tube 2 having the part 9 by the cured adhesives 10. Thereby, the inflow of a gaseous mixture to be supplied into the tube 2 having the part 9 is obviated.

摘要： PURPOSE:To manufacture a hollow membrane separation module of high reliability efficiently, by inserting the bundle of the hollow membraes into the end of a main body and inserting a closing object to close clearance between the main body and the bundle of the hollow membranes, then feeding the unhardened adhesive. CONSTITUTION:After a bundle of hollow membranes 104 is inserted in a main body 101 and a closing object 114 is inserted to the end 102 of the main body 101 and the clearance between the main body 101 and the bundle of the hollow membrane 104 is closed. Then, the main body 101 is held vertically, and the unhardened adhesive 106 is fed, stayed, filled and penetrated into the interstic between hollow membranes. Thus, because the adhesive is penetrated in the bundle of the hollow membranes by capillary action, also adding gravitation, the hollow membrane separation module of high reliability can be manufactured efficiently.

摘要： PURPOSE:To attain the separation of gases with a predetermined separation performance and a large separation coefficient by incorporating a mixed gases separator using a membrane in a constant-temperature tank controllable to any temperature. CONSTITUTION:Gases to be separated, supplied from the mixed gases source 1, are raised its pressure to a given pressure by the compressor 3, passed through the heat exchange tube 4 to control its temperature to a given temperature by means of the constant-temperature tank 5, and then put into the high-pressure chamber 8 of the gas separation cell 6 being controlled to a given temperature by the constant- temperature tank 7, where part of gas permeats the membrane 9, enters the low- pressure chamber 10, and then reaches the separated gas trap 12 through the conduit 11. Gas which failed to permeat the membrane passes through the flow regulating valve 14 from the discharge pipe 13 and then reaches the separated gas trap 15.
