    Abstract: The invention relates to bichromophoric benzotriazole-benzoxazole compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the bichromophoric composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may also be incorporated into the organic compositions in the polymer melt or dissolved in the polymer dope, coated on the exterior of the molded article, film or extruded fiber.

    Abstract: Benzoxazole or oxadiazole type compounds chemically combined with certain hydroxyaryl type compounds give greatly and unexpectedly improved ultraviolet stabilization to polymeric materials at concentrations ranging from about 0.05 to about 5.0 percent by weight, preferably from about 0.1 to about 2.0 percent by weight of the polymer being stabilized. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including pigments, colorants, fillers, reinforcing agents and the like. These stabilizers may be incorporated into the polymer melt, dissolved in the polymer dope, or coated on the exterior of the molded article, film or extruded fiber.

    Abstract: A splint product is used for forming a hard structure about a body portion. The product includes a substrate impregnated with a resin that hardens when exposed to water. A protective water-impervious envelope surrounds the substrate and shields the substrate from exposure to moisture in the atmosphere. An outer cushioning wrap surrounds the protective envelope and is for engaging the body portion. Prior to wetting of the splint product, the protective envelope is removed from its shielding position about the substrate so that the substrate remains inside the outer wrap. The outer wrap with the substrate therein is exposed to water and applied to an appropriate body portion about which it hardens.

    Abstract: A reed valve assembly includes a two ported base member adapted for placement within a fuel/air supply of an engine. The base has a reed cage with first and second reed cage faces defined on the downstream face such that the faces of the reed cage define an upright V opening downstream relative to the base. Reed petals cover openings in the reed cage faces and prevent back flow from the downstream side to the upstream side of the valve assembly. Flow from the upstream side to the downstream side is accomplished by the reed petals flexing towards one another. The reed petals are held in place by a clamping bar, which allows adjustment of the flexing tension for fine tuning of valve operation.

    Abstract: An air seed meter which dispenses individual seeds supplied by a seed hopper into a furrow at a controlled rate as the meter and others like it are advanced over the ground has a generally cylindrical housing containing a rotatable seed disk. As the seed disk is rotated past a mass of seeds on one side thereof, a plurality of seed cells formed by recesses in the surface of the seed disk at one or more circumferential rows of holes adjacent the outer periphery of the seed disk mechanically accelerate and eventually capture therein individual seeds from the seed mass. The individual seeds are held within the cells by a pressure differential created by a vacuum source coupled to the inside of the housing on the opposite side of the seed disk until the cells reach a discharge area. At the discharge area, the effects of the vacuum are cut off so as to release the individual seeds from the cells for discharge through a chute at the bottom of the housing to a seed furrow below. Agitation of seeds within the seed mass with the accompanying mechanical acceleration and capture of individual seeds within the cells may be enhanced by providing fins on the surface of the seed disk and is facilitated by a cell configuration which has a rear wall of greater slope than the front wall of the cell. Doubling of seeds within the individual cells is minimized by limiting the size and depth of the cells relative to the seed and also by use of a relatively low pressure differential which is made possible by the manner in which the cells agitate, mechanically accelerate and then capture the seeds. As a result there is no need for cumbersome and elaborate multiple seed eliminating arrangements.
