They Invented What? (No. 145)

Posted in They Invented What? by Jake Ward on July 30, 2009

U.S. Patent No. 3,307,285:  Pneumatic method for catching or scaring fish.

 looknoexplosives

What is claimed is:

1.  A method of preventing movement of aquatic organisms in a body of water toward a prohibited region thereof comprising:  placing at least one pneumatic shock wave generating device in said body of water between said prohibited region and said aquatic organisms; and actuating said device to explosively release high pressure gas, thereby producing a shock wave in said body of water rising to an initial pressure peak within 25 five milliseconds and propagating at high velocity.

JW Note:  Will be out over the next week for my annual fishing trip – so today’s TIW? theme seemed appropriate.  Will be thinking about patents only occasionally next week, for example, during those times when the walleye are not jumping into my boat!
