Gas cannons

Gas Cannon Device, patented by Peake in 1934(Ref), was claimed to be an improvement for previously proposed "gas cannons . The object of this device was to provide a gas generating propellant in measured form. 

Gas Cannons. The first cannons were small, crudely made cast metal pots shaped like a vase which fired iron darts. The invention of gun powder about the middle of the 13th century made possible the use of cannon to throw projectiles by use of expanding gas.

Climax A process for making sodium sulfate from sulfuric acid and sodium chloride. Sulfuric acid is sprayed onto a hot fluidized bed of sodium chloride. The products are granular sodium sulfate and hydrogen chloride gas. Invented in 1967 by C. K. Curtis later developed and commercialized by C. W. Cannon at the Climax Chemical Company at Midland, NM, in the 1970s. Midland was a favorable location because of the proximity of mineral salt and sulfur from petroleum and the availability of cheap transport of the product from the site. French Patent 1,549,938. 

DR. RODERICK CANNON (University of East Anglia) I d like to hazard a guess that much of the progress in understanding electron transfer reactions will come in the future from studies on the solid state, on the one hand, and from gas phase studies on the other. And I have felt, having reviewed the literature fairly recently, that both of those areas have been most neglected.

The production of hot gas to lift and move objects, using a pyrotechnic system, began with the development of black powder. Rockets were in use in Italy in the 14th century [51, and cannons were developed at about the same time. The development of aerial fireworks was a logical extension of cannon technology.

The early attempts to devise a bronze breech -loading cannon were unsuccessful because the backward pressure of the gas ultimately blew out the breech-block or else the gas created sufficient pressure against the walls of the barrel to burst it. As forged-alloy steels were perfected, breech-loading became a more practical possibility at the same time steel hoops or outer tubes were shrunk onto the barrel to strengthen it, or, at a later date, wire was wound around the barrel at high tension(Ref 2,p 83)... 

The purpose of a cartridge case(especially when used in recoil-type cannons) is not only to serve as a container for proplnt, primer and projectile, but also to prevent the escape of gas from die rear of weapon on firing the proplnt. 

An opening in the closed end (base) is provided for insertion of the muzzle of a special cannon (mortar). The first few meters of the closed end are separated from the open end by means of a paper partition, and this section is called "explosion chamber or gas chamber"...
