A device for cyclically rearranging a stack of rectangular sheets may fail due to uncontrolled displacement of an individual sheet to be exchanged. To avoid such malfunction the device includes , springs (200a, 200b) which maintain alignment of that individual sheet with thrust-supporting stops (66). The stops may be designed to sense the thrust to which the individual sheet is subjected so as to permit or to prohibit exchange.

Why it's free to use
- Filed January 15, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 15, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 15, 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.
