A computer program has been set up in Fortran language to calculate pore size distribution using the Cranston-Inkley method of calculation. Nitrogen adsorption isotherms were determined on amosite and chrysotile asbestos at - 195 degrees C. Size redu

In previous work the authors showed that chrysotile is more porous than amosite and consequently has a higher surface area. In the present work, water with a low molecular cross-section and benzene with a high molecular cross-section are used as adso

An automated gravimetric measuring system has been developed to study adsorption and desorption of gases on fine powders. With interchangeable Dewar and furnace systems, the temperature range of weight change measurements is −196° to 500°C. The h

A method for preparing titanium tetrachloride is described which consists of reducing rutile with coke and chlorinating the reduced product at 200° to 500°C. The crude distillate is purified by treatment with copper powder and distillation. Recover

Lung samples from 30 bituminous coal miners have been analyzed for coal and noncoal dust. The latter has also been analyzed for quartz, other crystalline substances, and metallic constituents. Initially, the sample is freeze-dried, and ground in a mu

The spray application of a polyurethane foam was monitored in an underground mine to determine the air concentrations of diisocyanate and the resultant human response. Results snowed that the majority of unreacted p,p-diphenylmethane diisocyanate (MD
