Abstract: An improved health food composition comprises; B complex vitamins; a prostaglandin E-1 precursor; a primary emulsifying agent; a flavoring agent; and a preservative. The B complex vitamins include: vitamin B1 (thiamine hydrochloride); vitamin B2 (riboflavin); pantothenic acid; vitamin B6 (pyridoxine hydrochloride); and vitamin B12 (cyanocobalamin). The prostaglandin E-1 precursor may be safflower oil. The primary emulsifying agent is selected from the group consisting of: Poly Sorbate-80; acacia; sodium alginate; carbomer (carboxypolymethylene); carboxymethylcellulose; and others. The flavoring agent is selected from the group consisting of: orange; lemon; and peppermint. The preservative is selected from the group consisting of: sodium benzoate; alcohol; ethyl paraben; ethyl vanillin; glycerin; and others. The improved health fod composition may further comprise a secondary emulsifying agent being selected from the group consisting of: hydroxyethyl cellulose; hydroxypropyl cellulose; and tragacanth.

Abstract: A hub assembly for roller skates having a flanged hub with a cylindrical body portion, a flat ring, and a hub plug. The body portion of the hub has a concentric molded opening therein with the ring end thereof adapted to be forced onto the axle nut of a roller skate wheel. The flat ring is disposed over the hub body against the inner surface of the flange so as to permit a plurality of projections on the inside face of the ring to form a frictional connection to the side wall of the wheel, such that rotation of the wheel causes the ring to rotate with the hub acting as a bearing. The hub plug is inserted in the outer end of the hub opening thereby giving a finished appearance. The assembly is preferably of a nylon plastic impregnated with phosphorescent or fluorescent dyes such that the assembly will glow in bright colors under ultraviolet light.
