Hydrogenating Oils, Fats, and Fatty Acids, Etc. J. N. Humphreys, June 23, 1914. U. S. Pat. 1,100,735. The oil to be hydrogenated is mixed with a finely divided catalytic agent and caused to move in a film relatively slowly and quietly over a circuitous path in an atmosphere containing hydrogen. Treatment of Petroleum Hydrocarbons. Bacon and Clark, June 23, 1914. U. S. Pat. 1,101,482. This process is designed for converting into gasoline petroleum hydrocarbons from which the usual gasoline content has already been removed by fractional distillation or hydrocarbons normally free from gasoline. The process consists in producing saturated gasoline hydrocarbons ( i .e . , hydrocarbons having boiling points ranging from about 30' C. to 150' C., a t atmospheric pressure), by simultaneously decomposing and distilling under a pressure of from IOO t o
"A." They are then mixed with hydrocarbon gases and the mixture heated to a high temperature in the gas converting chamber " B," thereby rearranging them in their combinations.

Combustible gases in the remaining mixture are recovered by cooling, whereby part of the impurities and the moisture are eliminated. Process of Making Bisulfite of Soda. H. Howard, July 28, 1914. U. S. Pat. 1,104,897. Lime-mud is reacted upon with sodium bisulfite, thereby forming calcium sulfite and sodium
ing point of about 250' C. and upward, the operation being continued a t a rate to give a yield of saturated gasoline hydrocarbons of a minimum volume of 18 per cent of the distilling charge, and subsequently treating the distillate thus obtained f q the separation of the saturated gasoline hydrocarbons. Carbon-Remover. C. B. Longenecker, June 30, 1914. U. S. Pat. 1,101,646. This is a compound for treating cylinders of internal combustion engines consisting of sodium chlorid and sulfur. Sulfur and Sulfates from Sulfites. C. Hansen, June 30, 1914. U. S. Pat. 1,101,740. Sulfur and sulfates are produced by heating solutions of a mixture of two molecules of a bisulfite with one molecule of a sulfite under pressure and with continuous stirring. Method and Means for Fixing Nitrogen. W. S. Landis, July 14, 1914. U. S. Pats. 1,103,060 and 1,103,062. Calcium carbid contained within a bag of loosely woven fabric is placed within porous vessel 3 in the chamber I and electrically heated, nitrogen being admitted through pipe 1 1 during the heating operation.
sulfite. Sodium sulfate is added and the resulting mixture is reacted upon with sulfur dioxid a t a temperature between 45' C. and 65' C., thereby forming calcium sulfate and sodium bisulfite. Calcium Acid Phosphate.
E. W. Reed, July 28, 1914. U.
S. Pat. 1,105,304. A moving body of air laden with the finely
Fertilizer. F. S. Washburn, July 14, 1914. U. S. Pat. I , I O J , I I ~ The . phosphoric acid contained in phosphate rock is rendered available as a plant food by treating the rock with sulfuric acid to obtain a crude solution of phosphoric acid and then feeding the crude solution so obtained to a solution containing di-ammonium phosphate. Rendering Smelter Fumes Useful and Recovery of Their Values. C. S. Vadner, July 14, 1914. U. S. Pat. 1,103,165. The smelter fumes are purified of their mechanical impurities by passing them through the mechanical filter in the chamber
divided phosphate material to be transformed into calcium acid phosphate is sprayed with sulfuric acid, the process being preferably carried out in the apparatus illustrated.
