Comic actor Danny Kaye received patent D166,807 for the co-design of "Blowout Toy or the Like". It's similar to one of those toys that unravels when you blow into at a birthday party except Kaye's has three blowouts going in different directions, not just one.

5472908Method for manufacturing a power semiconductor component for high speed current switching
The destruction-free rapid dismantling of current of power semiconductor components can be substantially enhanced when the inhibiting pn-junction is produced with a polished surface of the semiconductor body. The pn-junction thus becomes so uniform that l...
