Abstract: A continuous process forms liquid or semi-solid suspensions of water-hydratable guar particles in a non-aqueous solvent directly from hydrated guar splits. In particular, guar splits are hydrated, compressed to form wet guar flakes, and then dried. The dried guar flakes are then combined with a non-aqueous carrier fluid. Finally, the guar and carrier fluid mixture is homogenized, and, if desired, the homogenized guar and carrier fluid mixture may be shear milled to further size-reduce the average particle size of the guar particle.

Abstract: A photomultiplier tube and a method and apparatus for molding an optical coupler thereto are described. An optical coupler molding fixture includes a frame and a frame base. A photomultiplier tube is positioned within the frame between a spring and a shim. The optical coupler is formed with a mold which is positioned against the shim. A cavity is created radially interior to the shim between the photomultiplier tube and the mold. The optical coupler is molded to a faceplate of the photomultiplier tube with the fixture oriented so that its longitudinal axis L is parallel to the ground. A clamping structure presses the mold against the shim and provides the optical coupler material a non-leak space in which to cure. The optical coupler material is injected into the mold through a fill hole, and may be injected at ambient temperature. Curing time may range from one week at ambient temperatures to four hours at 65° C. The mold can be machined to create any form desired for the optical coupler.
