ACETYLENE RENDERED HARMLESS.

ACETYLENE RENDERED HARMLESS.

According to former John S. Seymour, United States commissioner of patents, by the use of a recent invention acetylene can be used for public and private illumination, without any danger of explosion. even if the gas is subjected to the test of an electric spark. To obtain this result the storage cylinder is packed with asbestos or brick disks —the latter of eighty per cent, porosity and filled with acetone. The acetylene is then pumped into the cylinder or tank under a pressure of ten atmospheres. Tt is found that the acetone dissolves, or absorbs the acetylene to the extent of one hundredfold the mathematical capacity of the cylinder. The gas is now being used on several railroads in this manner for illuminating purposes. William McDevitt, of Philadelphia, inspector for the fire underwriters, said that the invention constituted the greatest improvement in the safe use of acetylene vet extant. With the gas stored in this manner, he believed that the element of danger of explosion was almost eliminated.
