John Bell Blish John Blish - American inventor.

John Blish was the US Naval Commissar. He received a patent in 1915 for the invention of a semi-free weapon. In this castle, the self-propelled delay (due to reduction of friction coefficient between the bolt and the chassis) occurs after the pressure of the dust gases (Blish effect) decreases. He has worked with John T. Thompson and his team since 1916 on the construction of an automatic weapon in which a lock was used to self-ignite his idea. Thanks to the cooperation, several models of automatic weapons have been developed, giving the Thompson family of machine guns a start. Bibliography

The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler.
