Abstract: A dual rotatable book holder designed to hold two books for quick and easy reference. Two plates form a two face book platform with lips extending outwardly hold two books back-to-back. The two face book platform is removably engaged with a rotatable base allowing the user to quickly and efficiently rotate the two face book platform. The rotatable base comprises an upper section and a lower section which snap-fit together. The fitted upper section and lower section form a circular enclosure which encases one or more sets of ball bearings allowing the upper section to rotate freely upon the stationary lower section. The ball bearings are held in place by slots incorporated within a channel of the upper section and a groove in the lower section. A pin and tubular section arrangement connect the two plates and hinges connect the lips to the two plates allowing the two surface book platform to be folded into a flat piece when removed from the base for easy storage along with the flat base.

Abstract: A polyester resin composition having improved neutron shielding properties can be made by mixing a condensation product of maleic anhydride, phthalic anhydride and polyethylene glycol dissolved in styrene, with at least a sufficient amount of pelleted polyethylene to substantially increase the neutron shielding properties of said condensation product, and a sufficient amount of curing agent such as benzoyl peroxide and N,N-dimethylaniline to promote the curing of the mixture to a solid product. The polyethylene having a relatively high hydrogen content reduces the energy of the neutrons. A powdered boron compound such as boric acid and/or a lithium compound can be incorporated in the composition in amounts at least sufficient to effect substantial thermal neutron capture. Cadmium can be incorporated into the composition being much more efficient at neutron capture than boron or lithium, but then provision must be made for stopping the capture gamma rays generated.

Abstract: An adjustable easel of generally triangular configuration mounted on a rotatable support disc or the like. The angle of inclination and/or the height of the front support for an oil painting or the like may be adjusted by either changing the length of the rear support, which pivots about its base, and/or by changing the distance between the respective base pivots of the front and rear supports. In addition, since the easel is mounted on a rotatable support, the entire easel may be turned in or to any position for best viewing and light, without motion of the painter or loss of concentration on the subject being painted. This feature in addition to the movable vertical adjustment allows the easel to be disposed at many angles or orientations as desired for best positioning relative to the object being painted and the light source.
