System for generating heat by converting electric energy into thermal energy by passing electric current through conducting bodies (12 16-18) of high conductivity, their thickness being measurable in microns and with a large ratio between width of the section and said thickness, said bodies being laid flat on their supports (11, 15) to create heat-emitting surfaces which not only heat but which diffuse as well.

Why it's free to use
- Filed March 30, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 30, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 30, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
