Abstract: ABSTRACT OF THE DISCLOSURE     The useful life and stability of fixer used in the pro-cessing of film through developer, fixer and wash stages is significantly improved by withdrawing used fixer, electrolytically removing silver therefrom, after stabilizing the withdrawn fixer by adjusting its pH to a substantially constant value and re-circulating thus-treated used fixer for further film processing.     Thus the present specification discloses a method for electro-plating a negatively-charged surface by removing metal ions from a thiosulfate-containing medium in contact with the negatively-charged surface and wherein the negatively-charged surface is not completely surrounded by a fluid barrier during electroplating.     The specification discloses an improvement which comprises (a) maintaining a voltage of from 0.1 to 2 volts across the medium, (b) maintaining through the medium a current in amperes which is at least equal to, but not more than about twice, the corresponding voltage in volts, (c) maintaining the pH of the medium at a pH of from about 4 to about 5, and (d) agitating the medium without aerating it.

Abstract: FLOW CONTROL VALVE ASSEMBLY WITH INTEGRATED TORQUE AND FLOW DIVIDER CONTROL                Abstract of the Invention A flow control valve assembly for controlling first and second reversible fluid motors for series or parallel operation has a direction control section and a torque control section provided in a single valve body.  The valve body has first, second, and third supply ports selectively pressurizeable by the direction control section and connected to a torque control bore in the torque control section.  First and third function passages extend from the torque control bore and are connectible to the first fluid motor, and second and fourth function passages extend therefrom and are connectible to the second fluid motor.  A grooved, torque control spool is disposed in the torque control bore for sliding from a series operating position wherein the grooves connect the first port to the first function passage, the second function passage to the third function passage, and the fourth function passage to the second and third ports.  The torque control spool is biased towards a parallel operating position wherein the grooves connect the first port and the first and second function passages in parallel and connect the second and third ports respectively to the third and fourth function passages for metered flow therebetween.  First and second sensing passages are fluidly connected to the second and third ports and are selectively interconnectible via a direction sensing valve in the valve body with first and second pilot passages which are respectively connected to first and second ends of the torque control bore.  The direction sensing valve operates to respec-tively connect the first and second sensing passages to the first and second pilot passages for the first direction of operation and interchanges the connection for the second direction of operation so as to move the torque control spool to maintain equal flow of fluid to the first and second fluid motors in either direction of operation.
