An apparatus (10) for liquifying tires is shown in a first form including a plurality of tire modules (12) holding tires which are immersed in and preheated by a slurry located in a tank (22).

Why it's free to use
- Filed August 16, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 16, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 16, 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.
