Open the CIPO recordAbstract From the Canadian patent
A system is provided for regenerating reducing agents used in ancillary chemical or electrochemical processes such as restoring solderability of electronic components to be soldered in a fluxless soldering process. The system includes a cathode an anode, and an, electrolyte system that is separated by a semipermeable ionic barrier into a catholyte and an anolyte. The catholyte includes the reduced member of a redox couple which can be, regenerated electrochemically. The redox couple of the electrolyte system is charged like a battery and discharged during the ancillary process. Regeneration of the reduced member of the redox couple is accomplished at the cathode which may evolve hydrogen …

Why it's free to use
- Filed December 10, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 10, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 10, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
