Correlation of cylinder-head temperatures and coolant heat rejections of a multicylinder, liquid-cooled engine of 1710-cubic-inch displacement (open access)

Correlation of cylinder-head temperatures and coolant heat rejections of a multicylinder, liquid-cooled engine of 1710-cubic-inch displacement

"Data obtained from an extensive investigation of the cooling characteristics of four multicylinder, liquid-cooled engines have been analyzed and a correlation of both the cylinder-head temperatures and the coolant heat rejections with the primary engine and coolant variables was obtained. The method of correlation was previously developed by the NACA from an analysis of the cooling processes involved in a liquid-cooled-engine cylinder and is based on the theory of nonboiling, forced-convection heat transfer. The data correlated included engine power outputs from 275 to 1860 brake horsepower; coolant flows from 50 to 320 gallons per minute; coolants varying in composition from 100 percent water to 97 percent ethylene glycol and 3 percent water; and ranges of engine speed, manifold pressure, carburetor-air temperature, fuel-air ratio, exhaust-gas pressure, ignition timing, and coolant temperature" (p. 207).

Electrodeposition progress report, September 1--30, 1948 (open access)

Electrodeposition progress report, September 1--30, 1948

Two difficulties which have been encountered in the attempts to prepare hydrofluoric acid solutions by precipitation and resolution are (1) dissolution of postum out of the solid precipitate leaving behind a solid bismuth compound and (2) the plastics used for a reaction vessel. Plastics tried have not held up under the combined effects of hydrofluoric acid, moderate heat, and alpha bombardment and the overall yield of the method is rather low. The plastics problem may be solved by the use of ``Fluorothene`` which is on order from the Atomic Energy Commission and should arrive soon. The problem of leaching the postum from the precipitate may be solved by careful control of pH during precipitation procedure to avoid the precipitation of as much bismuth as possible.

Process research progress report, April 1--30, 1948

Word was received that the Eimco filter has been shipped from the Salt Lake City plant. It is expected within two weeks or about May 10, 1948. In place of a float gauge referred to in the Process Research Progress Report, March 1--31, 1984, a Uehling Tank-O-Meter will be used on the chemical solution tanks for the W. D. Building. Word was also received that the steam ejector has been shipped. It can be expected within the next few days. This item will complete the equipment to be used for the removal of activity from the flue gases produced in the incinerator. Laboratory experiments using synthetic bismuth chloride solutions are considered as completed for the time being. The experiments have shown that good yields, and adherent deposits can be obtained from solutions containing 0.18 g. bismuth/ml. with a 7 N hydrochloric acid concentration, providing a diaphragm is inserted between the anode and cathode. Neither calcium chloride nor pyrogallol are necessary under the conditions mentioned above. Bismuth was plated from a production solution in Run EP-1 in which the activity has been reduced from 4.2 {times} 10{sup 7} c./min./ml. to 4. 2 {times} 10{sup 4} c./min./ml. A yield of 2.48 g./amp.-hr. …

The changes in the blood of humans chronically exposed to low level gamma radiation (open access)

The changes in the blood of humans chronically exposed to low level gamma radiation

Ten individuals received an average of 0.211 roentgens of gamma radiation per week for a 77 period week (December 1946-June 1948) for a total average dose of 16.21 roentgens. During this period these 10 men carried out an experiment involving materials which emit gamma radiation and were monitored by daily film badges. The radiation delivered during a week was received in a five day work week and usually they received approximately one-half of their weekly dosage during one of the five days. A significant fall in total white blood count and absolute neutrophil and lymphocytes count was observed during the 77 week period. The degree of fall in counts would not have been predicted from experimental irradiation in animals and so other unknown factors may have been causal agents. It is suggested that hematological and exposure data from other laboratories be analyzed statistically to confirm or disprove the effect of such low- dosages of ionizing radiation on humans.
