Abstract: Coated Particulate Fillers Abstract Filler particles are coated with an adduct of an unsaturated polymer, e.g. polybutadiene, and phosphinic acid groups.  The coated filler may be prepared by reacting an unsaturated organic polymer with a phosphorus trihalide and applying the product in the form of a solution or dispersion in an organic solvent  to mineral, e.g. calcium carbonate, particles.  If liquid, the product may alternatively be applied as such to the mineral particles.  In either case, the product so applied is then hydrolysed in situ in order to form the phosphinic acid groups.  The coated filler particles are useful in the reinforcement of elastomers.

Abstract: Abstract of the Disclosure A washing machine includes a washing tub whose peripheral wall is constituted by an upper peripheral wall section and a lower peripheral wall section which is located below the upper peripheral wall section and which is driven to rotate clockwise and counterclockwise.  The washing tub receives water and laundry therein.  In the case of a small load of laundry, the laundry is caused to flow, and to be washed due mainly to the flow or water caused by the rotation of the lower peripheral wall section.  In the case of a large amount of the load of laundry, the laundry can be due to the synergetic action of the frictional forces.  In such a washing machine, the inner surface of the lower peripheral wall section is made gradually larger in diameter from its lower portion to its upper portion.

Abstract: ABSTRACT OF THE DISCLOSURE         A multi-stage metallic pump or chemical pump with plural impellers arranged in series.  The impeller of the first-stage is integrally provided with radial flow ribs on the under surface of the impeller and with backside radial ribs on the upper surface of the impeller, which are larger than the front radial flow ribs as regards the diameter of the circle formed by the respective tips of the ribs.  A flange is formed as an extension beyond the circumference of the first-stage impeller and is integrally provided with a protruding ring on the upper surface of the flange.  The protruding ring rotates in a fixed recess formed in a casing, with a certain gap kept.  Because of the rotation, the liquid which flows into the clearance between the fixed wall of the casing and the rotating ring creates a turbulent flow there, preventing movement of air therethrough.  As for liquid leaks, since the backside radial ribs are larger in outer diameter, they are higher in peripheral speed and pressure and thus force back the liquid migrating from the radial flow ribs.  Thus the liquid is stopped.  Therefore, no seal member is required.
