Abstract: A method for preparing cracking catalyst. The method comprises making catalyst slurry having a homogeneous distribution of molecular sieve slurry, pseudoboehmite, clay, inorganic acid and aluminum-containing binder; and subsequent spray drying. Inorganic acid is added prior to the addition of pseudoboehmite; addition of molecular sieve is added after the addition of inorganic acid; and a phosphatic dispersant is added during preparation. Compared to conventional methods of preparing FCC catalyst slurry, the inventive catalyst slurry viscosity is decreased and the fluidity thereof is improved, while catalyst anti-friction is maintained. The solid content of the FCC catalyst slurry can be increased to about 40% or more. The gel forming time is significantly reduced with increased productivity and decreased catalyst production cost. Meanwhile, the catalyst has high pore volume and improved micro-reactivity. Overall reactivity performance of the catalyst is also improved.

Abstract: A framework for and hosting rendering plug-ins in remote access services is disclosed. The framework provides an interface between the core components of the remote access system and the rendering plug-ins. The framework utilizes public APIs to provide the interface between the core components and the rendering plug-ins. Using the APIs, the framework can allow various existing and new rendering plug-ins to interact with the core components of the remote access system, thereby making an extensible system that can support a variety of rendering plug-ins.

Abstract: An electronics system communicates among its subsystems by a free-space optical bus. The bus transmits signals bidirectionally along a single linear axis as polarized beams of light. Each subsystem has a bus interface unit for generating outgoing beams along both axial directions, and for receiving incoming beams from both axial directions. The interface units use laser generators, photodetectors, and amplitude beam splitters.

Abstract: An optical communication signal source package and assembly for coupling optical signals to the end of an optical fiber includes first and second semiconductor laser diodes capable of being operated in a redundant fashion for increased reliability or to provide wavelength division multiplexing for increases in bandwidth and information carrying capability. The laser diodes are supported with their mounting flanges in a common plane and are oriented to provide parallel beams of polarized light having perpendicular E-field vectors. A connector carried by the support positions the optical fiber at the target area where an optics system focuses the light beams. An optical coupling device such as a polarizing beam splitter or a holographic beam separator is responsive to the orthogonal light beams to direct both light beams toward the optical fiber with minimum decrease in amplitude. The package includes no moving parts or highly frequency selective components.
