IN the course of experiments on coal-mine ventilation factors which the Bureau of Mines has been conducting for the past two years at its experimental mine near Bruceton, Pa., tests were made in order to determine the leakage of two air-locks which had been placed in the mine. Each air-lock consist

THE U. S. BUREAU OF MINES, in cooperation with the State of Colorado, is conducting investigations at the University of Colorado to obtain fundamental data on the retorting of oil shale, particularly as regards, the effects of certain variable factors in retorting on the quantity and quality of the
A new concept in which oil shale is rapidly heated and retorted in the absence of shale ash is proposed. The shale heater is a bank of horizontal tubes, where shale particles are conveyed in dilute phase, immersed in a fluidized bed of combusting spent shale. The process is illustrated by computer s
