Title: Refining method for copper
Inventor: SAITO HIDEOMI
IPC: C22B15/14
Filed: 1986-01-27
Abstract: PURPOSE:To improve the production efficiency of blister copper and to obtain the copper having a high grade by charging the copper sulfide recovered from the slag generated in a converter into a refining furnace before charging of the blister copper thereby melting and removing the magnetite deposited in the refining furnace. CONSTITUTION:A silicic acid is added to the melt of the copper metal from which impurities are removed to some extent in the previous stage. Gas such as air or air enriched with O2 is blown thereto. The iron in the melt is thereby oxidized by which the iron oxide thereof and the silicic acid are bound and are removed as the slag. Said slag is then cooled with air and is processed in a flotation stage by which only the lumped copper sulfide is recovered. The copper sulfide is charged into the refining furnace before charging of the blister copper and is brought into contact with the magnetite (Fe3O4) deposited on the bottom of the furnace to decompose Fe3O4 to removable FeO as expressed by the formula. On the other hand, the copper sulfide is decomposed to gaseous SO2 and the free copper to improve the grade. The molten blister copper produced in the converter is charged into the refining furnace after the removal of the Fe3O4 and is subjected to stages for oxidation and reduction, by which impurities are removed. The copper is then cast to form an anode for electrolytic refining having >=99.2 copper grade.

Title: Multiple-type carbureter
Inventor: NIIMURA YUKIE
IPC: F02D9/02
Filed: 1981-02-06
Abstract: PURPOSE:To enable to avoid generating vibrations or the like due to combustion characteristic differences between cylinders by a method wherein throttle valves are provided respectively with passages of different sizes, in a multiple-type carbureter in which throttle valves for each carbureter are interlocked with each other. CONSTITUTION:In operation, air is sucked in through air intake passages 2a, 2b and is mixed with fuel which is supplied through main ports 6a, 6b. The resultant fuel-air mixture is introduced into scavenging chambers 4a, 4b through reed valves 3a, 3b, and the engine revolution speed is controlled by the throttle valves 10a, 10b. The valves 10a, 10b are rotated by a single shaft 11, so that the degrees of opening of the valves are equal. But at the time of idling, the amounts of air sucked in through the valves 10a, 10b are different from each  other due to the opening-area difference between the through-holes 12a and 12b  which are respectively provided in the valves 10a and 10b. Accordingly, in the  case of an engine having differences in the length of suction or exhaust passages, the problem can be overcome, for example, by connecting the suction passage 2a having the larger through-hole opening area to a cylinder for which the  passage is longer.
