Abstract: ABSTRACT.      The two stages gravity method of concentration of fine dry materials makes use of the differences in the specific gravity of the materials by using principles fairly similar to those used in wet shaking table.The dry materials are load-ed in a continuous series of troughs as they pass successively underneath a loading means as they travel conveyor belt like in a close circuit and,as they travel they are firstly submitted to a series of cyclic directed shaking motions transversal to the troughs and secondly,to a series of similar cyclic shaking motions parallel to the long axis of the troughs,the whole resulting in the production of a concentrate,and of middlings and waste which are unloaded in suitable receivers as the troughs turn downward in their conveyor belt like circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a process for preparing a polymer composition containing a physiologically active substance.          The process is characterized by contacting one or more polymer-izable monomers and the physiologically active substance, forming them into a specific shape and irradiating the shape with light or an ionizing radiation at a low temperature below room temperature to polymerize the polymerizable monomers.  The polymer is a highly desirable material for use as a supporting carrier and allows for the release of the active substance in a controlled manner.  The process of this invention allows the active substance to be carried in the carrier in a uniform amount and to be released therefrom  at an appropriate rate.  The structure of the polymer is such to allow for this release and the active substance may be carried by the polymer at a low temperature to prevent un-desirable side-effects.

At least one core leg having a preferably circular cross-section and composed of laminated magnetic material is arranged in the frame between the two yokes.  Between the ends of the core leg and the yokes are arranged cross-flux plates of laminated magnetic material in order to distribute the flux between the legs and yokes. The laminations in the cross-flux plates are oriented to be perpendicular to the laminations in the yokes.          Each cross-flux plate covers at least the full width of the yoke and at least the complete width of the core leg.  The width of each plate is suitably as great as the diameter of the winding which is arranged around the core leg.  Each plate will thus act as a mechanical support for the ends of the winding.  It is suitable to arrange spacers of non-magnetic material between the end of the core leg and each plate and between each plate and the adjacent yoke.

Abstract: BUTTERFLY VALVE HAVING CARTRIDGE            CONSTRUCTION WITH IMPROVED BEARINGS          Abstract of the Disclosure A butterfly valve is provided having a disc adapted to be rotated between an open and a closed position.          A valve seat made of resilient material is adapted to engage the disc in the closed position.  The valve seat has an outer wall surrounding the disc and has an aperture therein.  A shaft has one end affixed to the disc and extends outwardly through the aperture.  A ring surrounds the valve seat and is permanently affixed thereto for preventing deformation of the outer wall of the valve seat.  The ring is made of a material that is much stronger and more rigid than the valve seat and includes a cylindrical lip defining an aperture in the ring.  This aperture is in line with the aperture in the valve seat wall with the lip projecting into the aperture in the valve seat wall.  A cylindrical collar surrounds the shaft and is positioned within the cylindrical lip and supported thereby.  The collar provides a bearing surface for the shaft.          The valve seat further includes a pair of flanges on the axial ends thereof projecting outward from the outer wall.  The ring is positioned between the flanges and spaced therefrom creating a pair of grooves, one groove being on each side of the ring.          The disc, the valve seat, the shaft, and the ring form a unitary valve assembly.  A housing is provided including two sections, each section including a pair of projections on the inner sur-face thereof for mating with the pair of grooves.  The sections are joined and cooperate with the ring and the outer wall of the valve seat to hold the unitary valve assembly within the housing.

Abstract: ABSTRACT          Liquid fan spray system for cyclically deflecting a liquid jet between extreme positions defined by a pair of end walls is assured of cold weather operation by expanding the liquid power jet.  In the preferred embodiment, one boundary wall of the oscillator is tapered about 5° from the power nozzle to the outlet throat, and the outlet or throat has the substantially same cross-sectional area maintained for a given. oscillatory angle by closing down the lateral extremities of the outlet throat.  This assures cold weather starting when the liquid has increased surface tension and viscosity while at the same time maintaining essentially the same fan angle of the cyclically deflected power jet.  The invention is particularly useful in providing all weather oscillation in windshield washer systems for automobiles.
