Abstract: A foam mattress made up of a number of segments each of which includes a sheet-like base member and a plurality of discrete spaced apart foam elements extending from a face of the base member wherein the elements have been integrally formed in a single molding operation along the base member. The segments are joined to one another at their respective bases to form a core from which the elements extend from opposite sides.

Abstract: This invention relates to a novel method and a novel generator, or source, for providing gaseous negative ions of selected metal hexafluorides. The method is summarized as follows: in an evacuated zone, reacting gaseous fluorine with an actinide-metal body selected from the group consisting of uranium, plutonium, neptunium, and americium to convert at least part of the metal to the hexafluoride state, thus producing gaseous negatively charged metal-hexafluoride ions in the evacuated zone, and applying an electric field to the zone to remove the ions therefrom. The ion source comprises a chamber defining a reaction zone; means for evacuating the zone; an actinide-metal body in the zone, the metal being uranium, plutonium, neptunium, or americium; means for contacting the body with gaseous fluorine to convert at least a part thereof to the hexafluoride state; and means for applying an electric field to the evacuated zone to extract gaseous, negatively charged metal-hexafluoride ions therefrom.

Abstract: A thin substantially flat elongated metal spoon has an attached stabilizing buoyant body member covering a major portion of one surface of the spoon leaving an exposed bill of the spoon for deformation to modify, if desired, the characteristic movements of the lure during movement through the water. The exposed second surface of the spoon is highly reflective and is provided with hook-attaching means. The bill portion is provided with means for attaching the lure to a fishing line. The resultant lure is characterized by being laterally self-stabilized but unstable in a vertical and horizontal direction so as to provide for darting and dipping actions.
