摘要:
There is provided a method for subjecting garment accessories to a surface electrolytic treatment, which can advantageously provide various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory while at the same time providing a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory. The method may further comprise the step of controlling the posture of the garment accessory such that the one side of the outer surface of the garment accessory faces the anode and the other side faces the cathode during passing electric current through the electrolytic solution. The method may further comprise the step of polishing at least a part of the outer surface of the garment accessory during passing electric current through the electrolytic solution.
摘要:
A magnetorheological fluid delivery system includes a mixing and tempering vesse, (52). Fluid, 11, is amitted to the vessel via a plurality of tangential ports, (55), created a mixing of the fluid in the vessel and promoting homogeneity. Fluid may be reconstituted in the vessel by metered addition of carrier fluid. A fixed-speed centrigugal pump, (66), disposed in the vessel pressurizes the system. Fluid is pumped through a magnetic-induciton flowmeter, (24), and a magnetic flow control valve, (86), having solenoid windings whereby MR fluid is magnectically stiffened to restrict flow.

An improved system for increasing the effectiveness of magnetorheological finishing of a substrate. An inline flowmeter is close-loop linked to the rotational speed of a pressurizing pump to assure that the flow of magnetorheological fluid (MRF) to the work zone is constant. A simplified capillary viscometer is disposed in the fluid delivery system at the exit thereof onto the wheel surface. Output signals from the flowmeter and the viscometer pressure sensor are sent to a computer which calculates the viscosity of MRF being delivered to the work zone and causes replenishment of carrier fluid to the work-concentrated MRF to return the viscosity to aim to assure that a constant concentration of magnetic solids is being provided to the work zone. Asymmetric pole pieces for the field magnet at the work zone extend the magnetic field along the wheel surface upstream of the work zone to permit full magnetic stiffening of the MRF before it engages the work piece, while minimizing fringing field in the vicinity of the viscometer, and to shorten the magnetic field along the wheel surface downstream of the work zone.
