Abstract From the Canadian patent

A flexible endless belt mountable on rotating elements has an outer and inner surface between first and second lateral edges and a plurality of longitudinally spaced-apart laterally oriented upraised flights on the outer surface. Each flight has a single medial portion offset in a rearward longitudinal direction from portions of the flight immediately lateral to the medial portion. Protrusions on the inner surface engage the rotating elements for endlessly rotating the endless belt in a forward longitudinal direction. Such an endless belt is particularly useful on a control apparatus for a stone slinger.

Why it's free to use

  • Filed July 14, 2005 and granted July 2, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 14, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
