Abstract From the Canadian patent
Guided missiles (10) which trail control umbilicals such as optical fibers (20) are launched from an array (16) of launch tubes (14) that point in the same direction. A swing arm (40) extends over the face of the array (16) to capture and move the umbilicals (20) of previously launched missiles (10) away from the portion of the array (16) from which the next missile (10) will be launched to, avoid interference between the launched missile (10) and the existing umbilicals (20). As each missile (10) is launched, the swing arm (40) recycles to capture the umbilical (20) of the newly launched missile (10).

Why it's free to use
- Filed October 4, 1990 and granted October 5, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
