Witte Title:  RECOVERY OF CYANIDE FROM WASTE         WATERS BY AN ION EXCHANGE PROCESS                  ABSTRACT OF THE DISCLOSURE        A process is described for the substantially complete recovery of cyanide reagent and metal forming water soluble metal-cyanide complexes contained in mill effluents and waste waters.  The process is comprised of a loading cycle wherein the metal-cyanide complexes are adsorbed onto a basic ion exchange resin and the free cyanide containing column effluent is returned to the mill.  The metal ions, which are usually mostly copper, nickel and zinc, and the complexing cyanide are eluted in the subsequent regenerant cycle by an acid solution having controlled pH and controlled redox potential, the latter being measured against the saturated calomel electrode.  The preferred oxidant to control the redox potential of the regenerant solution is hydrogen peroxide.  The generated hydrogen cyanide is sparged with air, or removed by subatmospheric pressure from the regenerant solution, and dissolved in an alkaline scrubber solution for reuse.  The metal ions are recovered from a bleed solution.

Abstract: Abstract of the Disclosure A  system  for  transferring  workpieces  generally vertically from a station at one height in a workpiece support or transfer device to a station at another height in another transfer device or support.  The workpiece is moved vertically by an elevator which travels along a path through the stations from a point below the lower station to a point above the upper station. To smoothly and rapidly move the workpiece the elevator is accelerated and decelerated and dwells at least when picking up and depositing a workpiece. To avoid collisions, interference and the necessity of precisely synchronizing movement of the transfer and elevator, when in its fully raised and lowered positions, the elevator is clear of and does not interfere with the transfer and supports and any workpieces in the stations.

Abstract: Abstract An apparatus for performing two successive work operations on a workpiece in an equalized force mode.  The apparatus includes a base; a yoke mounted for bi-directional movement on the base and carrying a two-sided punch on its upper face; a ram member mounted within the yoke and including two bores opening in opposite faces of the ram member and slidably receiving two pistons secured to the opposite end walls of the yoke; and means for delivering pressurized fluid through the pistons to sealed pressure chambers defined at the inner ends of the pistons between the piston inner ends and the respective confronting faces of the ram to selectively move a pair of die members carried on the upper face of the ram into and out of punching coacting with the double punch carried on the yoke.  A force balance system acts to initially move the ram on the yoke in response to the introduction of pressurized fluid to either sealed chamber whereafter, upon engagement of suitable stop means, the pressure fluid acts to move the yoke on the base in a complimentary direction to bring one of the punches into coaction with one of the die members whereafter the pressure fluid is routed to the other sealed chamber and a similar sequence follows to achieve the second punching operation involving the double punch and the other die member.

The first selector converts N insertion codes such as a frame synchronization code and a service code into one code signal train on the basis of the second signals.  The second selector receives a digital data signal train having an alternate repetition of a digital data signal using (M -1) continuous time slots and a gap of one time slot and inserts the insertion codes of the code signal train on the basis of the first signal.
