摘要： Apparatus for trimming the side corner edges of a planar article such as wooden or particle board. The apparatus includes a pair of spaced rotary cutters adjustable to vary the distance between them to accommodate various thicknesses of articles to be trimmed, and a spring biasing member on one cutter to allow automatic movement of the cutter in the event that the article is warped or there are slight variations in the thickness of the edge being trimmed.

摘要： A container comprising an inner glass receptacle and a closely adhering, but not chemically bound exterior protective sheath substantially covering said receptacle. The exterior protective is comprised of a shape-retaining, preferably thermoplastic resin adapted to restrain and retain glass fragments should the glass receptacle become broken. The sheath is further provided with a plurality of outwardly protruding nodular means that minimize the container surface frictional characteristics, increase shock resistance and provide maximum non-slip characteristics to the sheath when the container is hand-held.

摘要： SOLUTIONS THAT HAVE BEEN USED FOR ELECTROLESS PLATING A WORKPIECE OF NON-CONDUCTOR MATERIAL, SUCH AS A RESIN, OR FOR STRIPPING METAL FROM A WORKPIECE ARE TREATED IN SUCH A MANNER THAT THEY MAY BE DISCHARGED AS NON-POLLUTING WASTE INTO A NATURAL BODY OF WATER. A USED SOLUTION IS FIRST PROVIDED IN A CONDITION INVOLVING A PH OF NOT GREATER THAN 8 OR 9, WITH AN OPTIMUM OF BELOW 5, AND THEN IF IT CONTAINS DISSOLVED METAL ABOVE ABOUT 5 G./L., IT IS DILUTED WITH WATER BEFORE FURTHER TREATMENT. THE SOLUTION IS THEN HEATED TO A TEMPERATURE OF AT LEAST 120*F. AND MAINTAINED AT SUCH A TEMPERATURE, WHILE PROVIDING ALKALINITY AND USING AN EXCESS OF SODIUM HYDROSULFITE OF AT LEAST ABOUT 50 MG./L., BUT PREFERABLY HIGHER, UP TO A MAXIMUM OF ABOUT 500 MG./L. THE SOLUTION IS THEN ALLOWED TO SETTLE AND IS DECANTED WITH LESS THAN ONE MG./L. OF DISSOLVED METAL CONTENT, AND WITH PRECIPITATED SOLID METAL WASTE BEING THUS REMOVED. SUBSEQUENTLY, THE THUS TREATED SOLUTION MAY BE RECIRULATED AND IF NECESSARY, FURTHER CONDITIONED FOR ITS PARTICULAR USE AND THEN EMPLOYED IN AN APPLICABLE RINSING OPERATION. ON THE OTHER HAND, IF DESIRED, IT CAN BE DISCHARGED AS A SUBSTANTIALLY NON-TOXIC WASTE SOLUTION.

摘要： POLYMERIC COMPOSITIONS THAT CONTAIN A PHENOLIC RESIN CONTAINING REPEATING UNITS HAVING THE FORMULA:

-CH(-R)-(2-HO,R''-1,3-PHENYLENE)-, -CH(-R)-(2-HO,HO,R''-1,

3-PHENYLENE)-, -SN-(2-HO,R''-1,3-PHENYLENE)-, AND -SN-(2-

HO,HO,R''-1,3-PHENYLENE)-

OR MIXTURES THEREOF WHEREIN R AND R'' ARE HYDROGEN OR ALKYL, CYCLOALKYL OR ARYL RADICALS HAVING FROM 1 TO 24 CARBON ATOMS, N IS 1 OR 2 AND THE AVERAGE NUMBER OF REPEATING UNITS IN SAID POLYMERIC COMPOUND IS AT LEAST 3, AND A METAL DEACTIVATOR HAVE UNEXPECTEDLY HIGH THERMAL OXIDATIVE STABILITY AFTER EXTRACTION BY VISCOUS LIQUIDS. THESE COMPOSITIONS ARE PARTICULARLY USEFUL IN THE INSULATION OF ELECTRICAL CABLES WHICH ARE UTILIZED IN ENVIRONMENTS LIKELY TO CAUSE EXTRACTION OF STABILIZER SYSTEMS.

摘要： Compositions which contain a blend of: A. A FIRST GRAFT COPOLYMER COMPOSITION DERIVED FROM THE GRAFT COPOLYMERIZATION OF A DIENE-BASED RUBBER WITH, FOR EXAMPLE, ACRYLONITRILE AND STYRENE, WHERE THE RUBBER HAS A MAJORITY OF ITS PARTICLES IN THE SIZE RANGE OF ABOUT 0.8 TO ABOUT 10 MICRON, B. A SECOND GRAFT COPOLYMER COMPOSITION WHICH HAS A MAJORITY OF ITS PARTICLES IN THE SIZE RANGE OF 0.005 TO ABOUT 0.6 MICRON, AND C. 1 TO 10 PARTS BY WEIGHT OF AN EPOXIDIZED SOYBEAN OIL OR A MONO- OR DISUBSTITUTED PHTHALIC ACID ESTER, E.G., DIOCTYL PHTHALATE, HAVE BEEN BEEN FOUND TO HAVE MUCH HIGHER Izod impact strengths at a given melt flow range than similar blends that do not contain the epoxidized soybean oil or phthalic acid ester for the same total rubber concentration in the blend.
