Abstract: Methods and apparatus for combinatorial (i.e., high-throughput) materials research, such as catalysis research, that involves parallel apparatus for simultaneously effecting mechanical treatments such as grinding, mixing, pressing, crushing, sieving, and/or fractionating of such materials are disclosed. The methods and apparatus are useful for mechanically treating catalysis materials and other solid materials, including without limitation, electronic materials such as phosphors, colorants such as pigments, and pharmaceuticals such as crystalline drugs or drug candidates. The simultaneous protocols and parallel apparatus offer substantial improvements in overall throughput for preparing arrays of materials, such as catalysis materials.

Abstract: The valve for a catheter includes an elasotmeric sheath for mounting over the end of the tube within a catheter assembly to prevent a backflow of blood. The valve also includes a sleeve of rubber or plastic which fits over the end of the sheath and which is resiliently expanded when the sheath is mounted on the tube so as to impart a circumferentially applied compressive force on the closed end of the sheath. The sleeve serves to maintain the wall in a sealed condition after a needle has been pierced through the wall and is subsequently removed.
