Title: Electrolysis of alkali metal chloride aqueous solution
Inventor: KAWASAKI KEIJI
IPC: C25B1/46
Filed: 1981-11-05
Abstract: PURPOSE:To availably utilize inexpensive electric power, by varying the supply amount of brine and the liquid level position of a cathode liquid corresponding to the variation of current load. CONSTITUTION:When current load is reduced, the supply smount of brine to an anode chamber is reduced to a predetermined amount and the overflow liquid level of a cathode liquid is raised to a predetermined position. Because a time is required until a liquid is accumulated in the cathode chamber and the liquid level position of an anode side is also gradually lowered, the permeation amount of a diaphragm is slowly changed. Corresponding to this permeation amount, current load is reduced. On the other hand, when current load is raised, the overflow liquid level of the cathode chamber is lowered and the supply amount of brine to the anode chamber is increased. In this case, because the liquid levels of the cathode and the anode chambers are rapidly stabilized, a speed for raising current load may be accelerated. By this method, inexpensive electric power during night or at an off-peak time can be used effectively.

Filed: 1981-11-04
Abstract: PURPOSE:To provide possibility of pushing out a grinding wheel in the fixed and radial directions even during revolutions, in a grinding wheel projection adjusting device for a honing machine under operation, by furnishing a differential gearing mechanism between the rotational driving shaft and grinding wheel. CONSTITUTION:When the projection of a grinding wheel 56 in the radial direction shall be adjusted, a fastening internal gear 32 is rotated in a case 4 by operating a handle. This rotation will cause a relative rotation of a gear for elevation and sinking 31 with respect to a shank 24 through a third planet gear 10 to shift compulsorily the fitting position of a boss 34 in a spiral groove 33 provided in the elevation/sinking mechanism 80, and thus the shank 24 moves in the axial direction to raise a projection adjusting member 41 with respect to the grinding wheel 56. Thus the grinding head 5 is released from its fast position. With this condition held, a worm gear 14 of a grinding wheel feed mechanism 70 is put in rotation to rotate the differential internal gear 12, and then the projection adjusting member 41 will make relative rotation to the grinding wheel holder 51 for adjustment of the projection of grinding wheel 56.

Title: Method for removing sludge in electroplating cell
Inventor: TOKUICHI KIYOBUMI
IPC: C25D21/18
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To intensify the stirring of liquid and to rapidly dissolve and remove sludge by blowing gas of a high pressure to the hydrochloric acid liquid in a plating cell. SOLUTION: The sludge 11 accumulating at the bottom of the plating cell 12 for applying electroplating on a steel strip 1 is removed by temporarily dissolving the sludge in the aq. hydrochloric acid soln. 8 at the time of washing the cell 12. At this time, a method for bubbling the liquid by sending air through an introducing pipe 4 is adopted for the stirring of the aq. hydrochloric acid soln. 8. The pressure of the air is set at +2 to 5 atm with respect to the water pressure around the gas blowing-off section. As a result, the powerful stirring not heretofore possible with a plating liquid circulating pump 10 is made possible and the rapid dissolution and removal of the sludge 11 are attained.  Since the free setting of the gas blow-off position by variously changing the arrangement of an air piping 7 and its holes is possible, even the sludge existing at the corners of the cell 12 not accessible with the circulation by the pump 10 is removable and, therefore, this method is effective for the electroplating cell having particularly intricate shapes.
