Filed: 1993-10-06
Granted: 1994-10-01
Abstract: The invention relates to a process for improving the degree of purity and especially the quality of colour and odour in valuable materials and mixtures in the field of wetting, washing and/or cleaning agents. In the process, a substance containing impurities and especially water-vapour volatile impurities is treated in finely divided form with superheated steam in the region of normal pressure in which bleaching agents may be used together with the substance for colour enhancement. In a special embodiment, the invention relates to the use of the process for drying aqueous preparations of valuable materials and/or their mixtures in the field of wetting, washing and/or cleaning agents in the spray region and/or eddy layer with the addition of superheated steam as the drying gas for the simultaneous cleaning of a substance contaminated especially with water-vapour-volatile impurities. This cleaning can be combined with an oxidising or reducing bleach dissolved at the same time in the substance to obtain brightly coloured valuable materials or their mixtures. If desired, traces of ozone may be added to the superheated steam.

Title: Plating cell with fluid powered wiper
Inventor: REYNOLDS H VINCENT
IPC: C25D17/00
Filed: 1997-12-02
Granted: 2001-01-11
Abstract: A plating cell for plating a flat substrate, for example, a stamper for a high-density compact disk recording, employs a sparger (36) to introduce a flow of electrolyte across the surface of the substrate (34) to be plated. A fluid-powerded rotary blade or wiper (72) within the cathode chamber (26) has a rotary blade (72) with an edge (73) spaced a small distance, preferably about a centimeter, from the substrate, and an annular turbine (80) which rotates under a flow of the electrolytic fluid that is also being fed to the sparger. The rotary wiper is run at a speed between 35 and 80 rpm and draws the electrolyte away from the substrate (34). This helps remove hydrogen bubbles that from during electroplating. A semipermeable weir (41) separates the cathode chamber (26) from an anode chamber (50) that contains an anode basket (52) filled with plating material. The plating cell is provided with a backwash flow regime so that impuritities and inclusions from the anode chamber are kept out of the plating bath.
