Abstract From the Canadian patent

A method and apparatus for impingement of fluid onto a moving surface. The apparatus (40) includes an asymmetric slot nozzle (50) having an opening (56) formed between an upstream wall (58) and a downstream wall (59). The nozzle (50) is disposed generally adjacent the surface (26) onto which the fluid is to be impinged forming an impingement distance between each of the walls of the nozzle and the surface. The impingement distance (60) of the upstream wall (58) is greater than the impingement distance (62) of the downstream wall (59) such that at least a portion of the fluid is delivered through the nozzle (50) in a direction that is counter to the machine direction (MB).

Why it's free to use

  • Filed October 22, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 22, 2022.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 22, 2024.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
