Abstract: An air purification system accepts foul air from a source of high pressure and treats the air so as to deliver an acceptable breathable air usable in any life support package. The components of the system are mounted on a portable cart. The foul air passes through a plurality of stages in going from the foul to the usable condition. The air is monitored at the various positions along the system to insure that the system is operational.
Abstract: A process for pelletizing sorptive mineral "fines" which includes adding sufficient moisture to the particles of sorptive material to occupy the pore space therein, compactly forming the moistened mineral in a pelletizing machine, then removing the pore moisture in a suitable dryer or kiln so that final pellets retain relatively the same absorbent capacity and bulk density as the original material.
Abstract: This invention relates to a roller for moving water on and simultaneously drying very large, flat hard surfaces such as tennis courts. The roller has an outer sleeve which is made from a foam whose compression load density and porosity values fall within critical ranges. The roller moves the water in the rolling direction as it simultaneously establishes a moving seal with the portion of the hard surface over which the roller rides.
