This invention relates to a process and apparatus for electroplating that has an electrolyte continually circulating through a rotating plating barrel along with its parts to be plated by having an elongated perforated tube that is positioned above the center of a barrel, whereby the barrel is provided with recirculated electrolyte by means of a pump recirculating electrolyte from a plating tank to the elongated perforated tube which in turn sprays the electrolyte on the parts from above the axis of rotation of the barrel through the perforations while the barrel is rotating, so that the parts are agitated and greater speed and efficiency of the plating process can be achieved.

Why it's free to use
- Filed August 8, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 8, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 8, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
