    Abstract: The hollow particles described in Specification 743,866 may be applied (with or without a sealing liquid) as a floating layer on volatile products to inhibit the evaporation thereof. Thus the evaporation of gasoline may be inhibited by applying hollow particles of ureaformaldehyde resin mixed with polyvinyl methyl ether. Specification 744,070 also is referred to.ALSO:The evaporation of volatile products is inhibited by covering the surface of the product with a floating layer of individual small, hollow, gas-filled, hole-free particles of a material inert to said volatile product (e.g. synthetic resin, sodium aluminate or silicate, cellulose derivatives, proteins and alginate particles) the particles having an average diameter of less than 500 microns and a liquid displacement of from 0.05 to 0.6. The particles, which may be prepared as described in Specification 743,866, may be applied as a floating layer of a foam containing also a non-volatile sealing liquid which sealing liquid may also be naturally present in the volatile product or not. The volatile product may be a volatile hydrocarbon, e.g. gasoline, naphthas and liquid butane, alcohols such as methyl, ethyl and isopropyl alcohols, trichloroethylene, liquid chlorine, oxygen or nitrogen, acetone, ethers, sugar solutions and electroplating solutions. The sealing liquid may be a non-volatile oil such as white oil. Specification 744,070 also is referred to.

    Abstract: RECOVERY OF BITUMEN FROM TAR SANDS Bitumen is separated from tar sands by contacting the tar sands with a small amount of liquid, heating the liquid treated tar sands to expand the liquid as a vapor thereby reducing the density of the bitumen and separating the bitumen from the remainder of the tar sands on the basis of density.

    Abstract: ROTARY ENGINE The present invention is a new rotary engine consisting of a stator with a cylindrical cavity, a hollow cylindrical rotor located within the cylindrical cavity of the stator, a power shaft along the axis of the stator and an eccentric mounted on the power shaft. A plurality of spaced vanes are mounted in the stator for reciprocal movement with respect to the stator to provide working chambers between adjacent vanes, the stator, and the rotor so that rolling movement of the rotor around the interior of the stator in response to combustion of explosive charges in the chambers causes the eccentric to roll around the inner surface of the rotor and thereby rotate the power shaft.
