Open the CIPO recordAbstract From the Canadian patent
A vertical axis washer is provided with a rotatable wash basket that has one or more inwardly directed baffles but no, central agitator structure. Surfaces are provided in association with the baffles, which may be in the form of ramps on the bottom wall of the basket, to cause the fabric load within the washer to move up the side of the basket wall and to slide along the baffles in a swirling motion as the basket is accelerated and decelerated during the washing cycle, which causes the fabric to be flexed and rearranged in the basket. This washer construction is particularly suited to be used in conjunction with a concentrated detergent solution wash cycle. 31

Why it's free to use
- Filed December 22, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 22, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 22, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
