Note: It is a very bad idea for any engineer to look at patent filings. If you are involved in a patent dispute and the other party can show that you have a history of looking at patents, it can make matters much worse for you.

The patent was filed in 1963 and granted in 1965. I don't think there's much concern over it being still in force.
And yes, the patent is for spinning a pregnant woman around rather quickly, with her head on the axis, causing the baby to pop out due to extra force. It's crazy. Although I'd contend, more valid than many software or business process patents granted in the last few years...
