Government scientist cools water to -6ʺ without freezing it. Washington, D.C., Aug. 9. The belief that water freezes at 32 degrees fahrenheit has been blasted by Dr. N. Ernest Dorsey, scientist of the National Bureau of Standards. Neither does all water freeze at the same temperature. These discoveries have been made by Dr. Dorsey after experimenting with 37 specimens of water taken from lakes, canals, and other sources. He has cooled water until it was minus 6 degrees fahrenheit that is, 38 degrees colder that the so called freezing point of 32 degrees. Yet it remained liquid, 8/9/38

Scotch machine, Washington, D.C., September 8. This machine, exhibited at the World Power Conference which is being held here, is devised so as to use every inch of matter contained in coal. The coal is put in the retort and heated to a temperature of 1832 degrees. From the smoke and gas, Tar, Ammonium Sulphite, sulphur, light oils and gas are derived and from the tar, medicines, aromatic oils, perfumes, dyes, and acids are derived. From the light oils, motor fuel is obtained. In short: this machine wastes nothing at all

Bantam, Connecticut. Defense homes. The heating unit is in the kitchen of Fred Heath's four-room apartment in the new federally-financed homes for eighty families just a few minutes from the Warren McArthur factory in Bantam. The well-insulated coal fire puts steam in the radiators and provides the heat for cooking. The tenants are well-pleased although on several nights when the temperature dropped to ten degrees below zero they were forced to replenish the fuel every two or three hours. That cigarette Fred Heath holds is not tailor-made, by the way--he likes to roll his own

Hanna furnaces of the Great Lakes Steel Corporation. Detroit, Michigan. Coke oven pusher. A long square pusher is inserted through the entire section of the coke oven, thus pushing the coke out to the other side into the freight car. This coke oven is a modern by-product oven. All the gases and vapors liberated from the coal in the cooking processes are recovered. The coal is heated from fifteen to twenty hours in a temperature of about 1700 degrees F. The gases and vapors released by the coal are condensed for the recovery of such by-products as tar, benzol, and gas. At the end of the coking period, the incandescent coke mass is pushed into the quenching car

Science and research. Studies of non-coking coals. V.F. Parry, supervising engineer of the Golden, Colorado field station of the U.S. Bureau of Mines is "sighting a coke bubble." This procedure is used to determine if a given coke has changed its properties or it is similar to another coke. One gram of powdered coal is heated at 820 degrees centigrade for two and a half minutes. The resulting "bubble" is then compared with a standard chart to determine its characteristics, as revealed by the shape it has assumed. This research is part of a project to find ways of improving the quality of coke from western coal
