Gobs of molten glass fall in succession into a scoop (8) which can be swivelled about a vertical axis and which supplies gobs to subsequent multiple delivery systems (3), for example of an I.S. glassware forming machine.

Why it's free to use

  • Filed February 28, 1992 and granted May 23, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 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.
