Side 103 - Years 1913 and 1914, compiled by AH Fay. 1915. 16 pp. Technical Paper 119. The Limits of Inflammability of Mixtures of Methane and Air, by GA Burrell and GG Oberfell. 1915. 30 pp., 4 flgs.
Side 10 - Parts per million (ppm) by volume is the ratio of the partial pressure of the water vapor to the partial pressure of the dry carrier gas.
Side 83 - The reaction is marked even when traces of these constituents are present in a gas mixture. Palladium separates out as a black cast or as particles suspended throughout the liquid. The authors found that 0.1 per cent of ethylene in a mixture of ethylene and air could be detected by the appearance of precipitated palladium when 200 cc of the mixture was passed through a 0.5 per cent solution of palladium chloride at the rate of 10 cc per minute. The reaction becomes more marked when the gas is shaken...
Side 64 - The method59'60 is based on the fact that a light brownish-gray suspension is formed in a few minutes when normal blood diluted with water, is treated with a solution of pyrogallic and tannic acids, whereas light carmine suspensions are formed with blood having carbon monoxide in combination with hemoglobin.
Side 83 - The reaction of palladium chloride on ethylene does not produce carbon dioxide. CALCULATIONS FROM COMBUSTION DATA. If the contraction and the volume of carbon dioxide from the combustion of the gas indicate methane only this constituent is reported. But if the data indicate higher members of the paraffin series a calculation is made that gives the two predominating constituents. The gaseous hydrocarbons react with oxygen as follows : CH4+2O2=COj+2H2O C2H8+3.5O2=2CO2+3H20 0,H8+502=3C02+4H20 C4H10+6.5O,=4C02+5H20...
Side 66 - If the blood does not flow freely, the finger is wrapped with the rubber hose, beginning at the base and progressing toward the tip; massaging the finger also aids the flow. (If death has intervened, it may be difficult to obtain liquid blood, but this usually can be done during embalming.) 2.
Side 98 - The globe used is a spherical glass bulb, sealed to a capillary glass stopcock that has been very carefully worked. In order to eliminate errors due to changes in the atmospheric temperature and pressure, and consequently to change in the buoyancy of the globe, a closed bulb having the same external volume as the density globe is used as a counterpoise during the weighing. The capacity of the globe is determined at about 1 6° C.
Side 64 - СО-hemoglobin (O, 10, 20, 30 per cent, etc.), arranged in a rack with spaces between for interposing tubes of similar size containing specimens of blood for analysis. 2. Small test tubes (of the same size and glass as those used for standards) for preparing specimens of blood. 3. A dilution pipette for measuring blood. The long capillary stem is calibrated to...
Side 71 - Dissolve 25 grams of pure white phenol in 150 cc of concentrated sulphuric acid, add 75 cc of fuming sulphuric acid (13 per cent SO'), stir well, and heat for two hours at about 100° C.
Side 50 - ... initial volume. The difference or contraction is the amount of carbon dioxide. The operator has no assurance that all of the carbon dioxide was absorbed unless he is familiar with the technique and the type of gas. Inexperienced analysts should pass the gas into the caustic pipette once more and note if the volume remains constant. Any further contractions must be added to the first. If more than five passes are required to effect complete absorption of the carbon dioxide in the ordinary fuel-gas...
