Patent JP-H10132194-A (JP)
Title: Float trap device of hydrogen cooled generator
Inventor: SHIDA KIYOSHI
IPC: F16T1/20
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent the scuffing phenomenon of a float valve and mixing of foreign matter by forming a partition plate between the lower end of the opening end of a drain oil pipe which leads a turbine shaft discharged from a bearing part to a float trap and the float valve in the float trap to which hydrogen gas pressure is being applied. SOLUTION: When turbine oil flows into a float trap 4 through a drain oil pipe 3 and an oil level 11 rises, a float 5 rises and a float valve 6 opens, so that the turbine oil flows out to the drain oil pipe 7. When the turbine oil is delivered smoothly and the oil level 11 lowers, the float valve 6 closes, so that hydrogen is prevented from leaking. At this time, the oil level fluctuates vertically when the turbine oil flows into the trap 4 from the opening end of the drain oil pipe 3, however, the fluctuation of the oil level is not transmitted to the float 5, thus it is possible to prevent malfunction due to scuffing of the float valve 6, because the oil level below the opening end of the drain oil pipe 3 and the oil level 11 on which the float 5 floats are partitioned from each other by a partition plate 12.

Filed: 1986-12-03
Abstract: PURPOSE:To obtain a thermosetting resin composition excellent in heat resistance and curability and suitable for solventless varnishes, laminating materials and molding materials, by using an N-substituted unsaturated imide compound and a pyridazine (derivative) as essential components. CONSTITUTION:A thermosetting resin composition prepared by using pyridazine or its derivative and an N-substituted unsaturated imide compound of the formula (wherein Y is H or CH3 and Z is an m-valent organic group), e.g., N- phenylmaleimide or N,N'-ethylenedimaleimide, as essential components. Although a resin system based on an N-substituted maleimide compound which is an addition type and produces no volatile by-product when cured (molded) has heretofore been used in order to impart heat resistance to class C solventless varnishes, laminating materials or the like, there is a difficult in simultaneously realizing rapid curability and heat resistance. The thermosetting resin composition of this invention excels in both of heat resistance and curability and is suited for, especially, solventless varnishes, laminating materials and molding materials.
