Abstract: Apparatus for transferring settled or suspended solids from an open vessel into a closed vessel, the apparatus comprising a suction line which extends from the closed vessel to the open vessel via drive means, such as a pump or compressor, and a solids feed line which extends from a solids outlet in the open vessel to a solids inlet in the closed vessel, a fluidising apparatus being provided to fluidise the solids in the open vessel.

Abstract: Apparatus for inhibiting fines carryover in the form of a settlement tank comprising: a filter which divides the tank into upper and lower portions; a fluid inlet in the lower portion for admitting into the tank a fluid with entrained solids; and a fluid outlet in the upper portion through which filtered fluid can leave the tank. The filter comprises filter media supported on a permeable wall, the wall including a filter media outlet which is normally closed, and opening means for opening the filter media outlet to allow the filter media to discharge into the lower portion of the tank.

Abstract: Apparatus for degreasing and electroplating wire with a high current density electrolyte at high speeds includes a supply reel, guide pulleys, driving drums, degreasing and washing tanks, plating tanks and a take-up reel. The speeds of the driving drums for plating and degreasing are related and controlled in accordance with wire tension by means of a pulley, spring-based pivotable dancer arm, and a variable resistor. Fluid drag by wires running in one direction is eliminated by placement of a plurality of closely spaced anodes across the top of the plating bath and a flow stabilizer plate over the degreasing tank. A control circuit provides a desired constant ratio between drive speed and plating current.
