Inventor: DEREKU KURAAKU
IPC: C25C1/16
Filed: 1991-11-18
Abstract: PURPOSE: To perform electrolytic recovery of a metal while controlling the generation of acid misting by incorporating,in an acidic solution of the metal, an anionic or cationic polyelectrolyte which is ionized under the electrolytic conditions and has a hydrophobic moiety in the molecule, and electrolyzing the resulting solution.  
     CONSTITUTION: This method for recovering a metal (such as zinc or cadmium) comprises: incorporating an anionic or cationic polyelectrolyte which is ionized under the electrolytic conditions and has a hydrophobic moiety (such as styrene or alkylstyrene moiety) in the molecule such that the surface tension of the surface of the bath is reduced sufficiently to produce foams, in an acidic solution of the metal; and then, electrolyzing the resulting solution, wherein the polyelectrolyte is derived from styrenesulfonic acid, vinylsulfonic acid, or the like and has a molecular weight of 10 4  to 10 7  and is incorporated in the acidic solution in a 0.25 to 5 ppm concn. Thus, the acid misting generated during electrolytic recovery of the metal can be controlled.

IPC: F16F9/34
Filed: 1989-12-19
Abstract: PURPOSE:To prevent the occurrence of pattering by providing a disc pressed to a main relief valve, which has a larger mass than the main relief valve and has a through hole, and disposing a subrelief valve on the outlet end of a sub port of a partition member. CONSTITUTION:A disc 35 capable of freely moving up and down is pressed to the upper surface of a check valve 12 which is a main leaf valve and a through hole 36 is formed in the disc 35. The disc 35 has a larger mass than the check valve 12, and the disc 35 is pushed downward by a spring 37. A valve element 27' which is thin and easily bent is provided on a sub leaf valve 27. In this arrangement, in a low speed range during elongation operation, oil in an oil chamber 24 is forced to flow out from an elongation port 16 through a time orifice into a lower oil chamber 5. When the speed is increased, oil from a sub port 28 pushes open the valve element 27' of the sub leaf valve 27 to flow out into the lower oil chamber 5. The sub port 28 is, however, such a small hole that the passage is not expanded suddenly. Accordingly, the vibration of a piston rod is restrained so as to prevent the occurrence of pattering of a car body.
