Abstract: Heavy metal ions are recovered from a dilute aqueous solution by flowing the solution through either a single bed of ion-absorbing material in successive forward and reverse directions, or through a first bed of ion-absorbing material and thereafter through a second bed of ion-absorbing material in the reverse directon of flow. The reversal of flow is to periodically mechanically agitate a bed of ion-absorbing material to dislodge contaminants, such as gelatin.The method is accomplished by using one enclosed vessel, or a pair of enclosed vessels, that have valves to control the direction of flow. A timing device preferably automatically reverses the direction of flow about each hour.After a relatively large number of reversals of flow the heavy metal ions are recovered from the ion-absorbing material and the same is regenerated in the process to again absorb ions from the dilute aqueous solution.

Abstract: The disclosure relates to an improved electrostatic paint spray system adapted for the application of conductive materials while at the same time providing for isolation of the electrically charged spray heads from the source of coating material. Heretofore, electrostatic paint spray procedures have been limited to a large extent to the use of non-conductive coating materials. Where it is appropriate or desirable to utilize conductive coating materials, it has been necessary to provide for the electrical isolation of the entire paint supply system, a circumstance which imposes severe practical limitations. The present invention enables an isolating stage to be provided within the coating material supply system, near the area of discharge, so that the "upstream" portions of the supply system are free of the high voltage electrical charge impressed at the spray guns, notwithstanding the use of electrically conductive coating materials.
