Nature's Miracles, Volume 1 Familiar Talks on Science—World-Building and Life. Earth, Air and Water. Thus, liquid oxygen and liquid air have been shown by Sir James Dewar to be almost perfect non-conductors of electricity. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" Not electron relays, nor plastic, nor liquid oxygen. Bear Trap Among these, as Professor Dewar discovered, is liquid oxygen itself. A History of Science, Volume 5(of 5) Aspects Of Recent Science It was stated in the literature sent all over the country by this company that their remedy was really liquid oxygen. The Eugenic Marriage, Vol. 3 A Personal Guide to the New Science of Better Living and Better Babies The driving power was derived from a combination of petrol and pulverised smokeless coal, treated with liquid oxygen, which made combustion practically perfect. The World Peril of 1910 The tube, a, fitted into an opening in the center of the lid; the tube, t, connected with an apparatus delivering liquid oxygen, passed through a hole on the right. Scientific American Supplement, No. 1082, September 26, 1896 Six more exhibited a temperature of near minus 320° F. These probably came from the liquid oxygen tanks. Pushbutton War There was powdered magnesium in contact with it and liquid oxygen all about. Scrimshaw We may safely feel certain that the nostrum was not liquid oxygen. The Eugenic Marriage, Vol. 3 A Personal Guide to the New Science of Better Living and Better Babies When the pressure is removed the liquid oxygen passes again into the gaseous state, since its boiling point under ordinary atmospheric pressure is -182.5°. An Elementary Study of Chemistry I, therefore, concluded that liquid air was a much more efficient cooling agent than liquid oxygen, and that it would be quite unnecessary to make further experiments on the liquefaction of helium. Scientific American Supplement, No. 1082, September 26, 1896 Chemical affinity is almost put an end to; phosphorus and potassium remain inert in liquid oxygen. The New Physics and Its Evolution Of course cotton sheeting in liquid oxygen is not quite as good an explosive as carbon-black, which they used down in the mine. Scrimshaw The bullet—a small, thin metal shell, filled with a secret chemical and liquid oxygen—went wild. The Air Trust Some experiments recently made by M. Olszewsky appear to show that liquid oxygen is one of the best of refrigerants. Scientific American Supplement, No. 497, July 11, 1885 When, as in some of my experiments, liquid oxygen was used in the inner vessel, this part of the apparatus was dispensed with. Scientific American Supplement, No. 1082, September 26, 1896 This liquid oxygen is then allowed to return to a gas and is stored in large gasometers or tanks. Oxy-Acetylene Welding and Cutting Electric, Forge and Thermit Welding together with related methods and materials used in metal working and the oxygen process for removal of carbon Less often he took out the CO2 snow, and measured it, and dumped an equivalent quantity of pale-blue liquid oxygen into the liquid air that had been purified by cold. Scrimshaw The huge floor, 150 feet in diameter, sloped gently downward toward the center; and here yawned another pipe, covered by a grating—the pipe to drain the liquid oxygen out to the pumping station. The Air Trust The temperature fell still further when the pressure on the liquid oxygen was reduced to nine millimeters of mercury. Scientific American Supplement, No. 497, July 11, 1885 The vessel, e, was partially filled with liquid oxygen, and, by means of a small siphon, a small quantity of the liquid was allowed to flow into the tube, a. Scientific American Supplement, No. 1082, September 26, 1896 The Professor tells me that liquid oxygen is obtainable only under great pressure, and at a colossal cost. Without Prejudice Down in the mine, blasting was done by soaking carbon black—from CO2—in liquid oxygen, and then firing it with a spark. Scrimshaw You and your President, too, aren't worth the liquid oxygen to blow you to Hades! The Air Trust Between it and the inner lining was a layer of cells, into which the men now pumped several pints of liquid oxygen. The Lord of Death and the Queen of Life In a second experiment the temperature of the liquid oxygen, boiling under 2 mm. of mercury pressure, was measured by means of a thermometer. Scientific American Supplement, No. 1082, September 26, 1896 Wherefore I doubt not there would be a public to adventure on liquid oxygen, though it were congealed in the attempt. Without Prejudice Then he went to the air-apparatus and took out a flask of the liquid oxygen used to keep his breathing-air in balance. Scrimshaw Just let's see some of the product—some liquid oxygen, that's all. The Air Trust Using the apparatus I have just described, I carried out two series of experiments, in which liquid air and liquid oxygen were employed as cooling agents. Scientific American Supplement, No. 1082, September 26, 1896 To determine whether the hydrogen thermometer is of any value at temperatures below -198� C. I carried out a series of experiments, in which I measured the temperature of liquid oxygen boiling under reduced pressure. Scientific American Supplement, No. 1082, September 26, 1896 My experiments have proved this statement to be incorrect; liquid oxygen does not solidify even when boiling under a pressure of 2 mm. of mercury. Scientific American Supplement, No. 1082, September 26, 1896 There, sir," he remarked, "is a half-pint of pure liquid oxygen, drawn from the air in less than eight minutes, at a cost of perhaps two-tenths of a cent.
