Dissolved Acetylene for Motor Vehicle Lighting.
Dissolved Acetylene is clean, dry, pure Acetylene stored in light steel cylinders under a moderate pressure. Before being charged with Acetylene, the cylinders are filled with a porous material in the form of cement, which is then hardened by baking into a brick from the pores of which all air is exhausted and replaced by a known quantity of Acetone. Acetone is a liquid hydrocarbon which has the property of absorbing or dissolving many times its own volume of Acetylene, with the result that at a nominal pressure of 150 lbs. to the square inch it is possible to store a hundred times the cylinder’s own volume of available Acetylene. In use, immediately the cylinder valve is opened, the Acetone commences to give off dry, pure, clean and cool Acetylene and will continue doing so until the contents of the cylinder are exhausted.
