Open the CIPO recordAbstract From the Canadian patent
Briefly, high output "popular" small frame alternators have a high rate of failure due to higher heat, temperatures typically caused by; 1) continuous higher rate charging 2) lack , of heat dissipation through, rectifier heat sinks & diodes 3) insufficient cooling (air exchange/air flow) through alternator and, components, 4) the "plugging up" of alternator by foreign matter such as chaff, dust etc...as is common, in agricultural mining and industrial applications and therefore limiting cooling causing "burn out". The invention consists of an improved alternator CE housing to allow for a larger rectifier with larger, heat sinks (and thus its exposed surface area) and 9 50amp diodes vs. …

Why it's free to use
- Filed July 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
