Open the CIPO recordAbstract From the Canadian patent
A cutting nozzle for a postmixed oxy-fuel gas torch is described. The cutting nozzle is an integral body having a cylindrical shroud which surrounds and extends away from gas discharge orifices in a gas discharge end of the nozzle. The cutting nozzle has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of preheat oxygen and fuel gas. The advantages include reduced machining time and material waste. The coupling of the nozzle to the torch is also facilitated and high quality performance of the cutting nozzle is promoted because alignment of the cutting nozzle in the torch head is ensured.

Why it's free to use
- Filed July 2, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 2, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 2, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
