Abstract From the Canadian patent

An improved fusing machine is provided that allows commutators to be balanced during the fusing process. Commutator tangs are compressed onto coil leads to form lead connections. The fusing machine compresses the tangs to varying degrees relative to the shaft. The commutator can be balanced during fusing by compressing tangs to a common radial position or by compressing diametrically opposed tangs to the same extent.

Why it's free to use

  • Filed November 15, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 15, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 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.
