A new method of using a veneer lathe to directly make fuel pellets from a log without intermediate milling. The new method defines a first dimension of the fuel pellet by cutting a veneer from the log of a thickness equal to the first dimension, and defines the dimensions of the cross section of the fuel pellet by cutting the cross section dimension to a depth at least equal to or greater than the first dimension. The cross section is perpendicular to the thickness dimension of the pellet.

Why it's free to use
- Filed June 3, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 3, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 3, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
