Abstract: The invention provides a method and apparatus for rinsing an object which has been removed from a chromium plating bath, and which has a source of chromium-containing anions thereon, while preventing the delivery of these anions to the environment. In carrying out the invention, chromium-containing anions are removed from the rinse water by an anion-exchange resin. The resin is periodically regenerated by backwashing it, delivering a dilute alkali metal hydroxide solution to the resin, delivering a more concentrated solution of alkali metal hydroxide to the resin, and by rinsing the resin. Effluent from the backwashing and the initial portion of the regeneration procedure is retained and later delivered to the resin. Effluent which contains a higher concentration of chromate ions, displaced from the resin, is delivered to a concentrated chromate solution storage tank.

Abstract: A refrigeration system incorporating a compressor sub-system which provides a source of higher pressure gaseous refrigerant to force liquid refrigerant into the receiver when condensor pressure is reduced sufficiently below normal to prevent it accomplishing the same purpose. When condensor pressure is insufficient to force liquid refrigerant from a pilot receiver tank to the receiver tank liquid accumulates in the pilot receiver tank to a level where it actuates a control valve, introducing said higher pressure gaseous refrigerant to said pilot tank and forcing liquid out. While condensor pressure is sufficient to the task, as is normally the case, the higher pressure gaseous refrigerant is received directly by the condensor.
