It is suggested to make the spindle washer without opening, hide all piston openings with a special metal partition, make two extended grooves (2, 3) in the inner working cylinder's wall, which would be separated from each other by the partition and to two hole openings (1).The suggested shock absorber construction is secure, has a longer service life and low prime cost.<IMAGE>
Patent LV-12003-B (LV)
Inventor: JANIS LICIS
IPC: C25C1/10
Filed: 1997-10-13
Abstract: This invention pertains to the extraction of chrome from used solutions, namely galvanic production wastewater cleaning of chrome.It is achieved by means of an electro-dialysis process to extract chrome (+6) with the hard ion exchange membranes, by placing anionite, e.g. AB-17, into the chrome extraction chamber. The process is carried out in the four-chamber dialyzer, in which the canal-type chrome extraction chamber is separated with a cation exchange membrane from the cathode side and with an anion exchange membrane from the anode side. The chrome concentration chamber behind the chrome extraction chamber is separated from the anode with the cation exchange membrane, which restricts migration of the chrome (+6) anions to the anode.On the separating surfaces (the cation exchange membrane from the cathode side and anionite) the dissociation of water molecules takes place and the appearing OH<-> ions migrate to the anionite layer and replace the chrome anions, which in turn migrate to the chrome concentration chamber.Thus, the whole process takes place in one stage, additional chemicals are not used, there is no waste and it is possible to arrange a closed water-supply technological cycle by cleaning wastewaters containing chrome.

Abstract: A process and apparatus for melting contaminated metalliferous scrap material are disclosed. The process comprises introducing the contaminated material (11, 72) into a melting furnace (12, 70), heating the material by means of a plasma (13, 71) at a temperature below the melting point of the metal at which the non-metallic contaminants are volatilized in an atmosphere which is preferably inert or has low reactivity with the metal under the process conditions while displacing at least some of the material (11, 72) within the furnace interior, withdrawing volatile contaminants from the furnace (12, 70), increasing the temperature in the furnace preferably while maintaining an atmosphere of low reactivity in the furnace in order to melt the metal while preferably displacing at least some of the material in the furnace interior, and removing molten metal (77) from the furnace. The process allows scrap material to be melted with good metal recovery without the need for separate decontaminating apparatus. The process can also avoid the need to shred the scrap and to add large amounts of fluxing salts to separate the molten metal from remaining dross. A rotary furnace (12, 70) heated by means of a contained arc plasma torch (13, 71) is preferably employed in the apparatus which also preferably comprises an incinerator (21, 79) for oxidizing the volatile contaminants withdrawn from the furnace.
