Open the CIPO recordAbstract From the Canadian patent
The invention relates to tongs for dressing conductor ends, having a pair of handles which can move relative to one another, at least two dressing stations and a drive device, via which the dressing stations can be driven during operation of the handles. At least one of the dressing stations can be coupled to the drive device with the aid of a conductor end which is to be dressed. The dressing station which can be coupled to the drive device is thus driven only when this is also required.

Why it's free to use
- Filed November 3, 1992 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 3, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 3, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
