Abstract From the Canadian patent

A hydraulic braking system for a pair of bobbin mounting cones. The system comprises pumps connected via sheets to each of the bobbin mounting cones, and are equipped with reduction units. The reduction units are connected to a source of hydraulic fluid by way of a reducer and value unit. The two pumps are hydraulically connected. As the speed of the mounting cones tend to increase the quantity of fluid flowing through the pumps is controlled by the reducer units which thus tends to brake the mounting cones.

Why it's free to use

  • Filed July 7, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 7, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 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.
