摘要:
A radiographic phosphor panel and radiographic phosphor composition. The radiographic phosphor panel includes a support and a luminescent layer. The luminescent layer overlies the support. The luminescent layer includes binder and coated particles. The binder is a film-forming polymer. The coated particles are embedded in the binder. The coated particles each have a core and a shell. The core is radiographic phosphor. The shell is exterior to and substantially encloses the core. The shell comprises vinyl-epoxy resin, having uncured epoxy groups in a concentration of from about 1.times.10.sup.-5 to about 60 percent by weight relative to the weight of the shell. The resin has a different composition than the binder.
摘要:
Apparatus for automatically removing bags from a supply conveyor and stacking a predetermined number of bags upon raised pins. The stacks are then placed on a stack transfer assembly that is then moved into a transfer station wherein the stacks are placed on wickets. An endless accumulator conveyor is arranged to deliver the wickets into the transfer station in timed relation with the movement of the transfer assembly between stations.
摘要:
A method of removing a toxic compound comprising contacting the toxic compound with a particle having two regions, the first region containing a detoxifying enzyme and the second region containing a material selected to partition the toxic compound into the second region. The particle may be a nanoparticle.
摘要:
An apparatus for accumulating a stack of bags having wicket receiving holes comprises a paddle wheel conveyor for placing bags, a motorized stacker wheel adjacent the paddle wheel conveyor to receive the placed bags from the paddle wheel, a plurality of stacker bar units each rotatably mounted to the stacker wheel and a pick up head operatively positioned adjacent said plurality of stacker bar units for receiving the stack of bags from one of the stacker bar units. The pick up head has two tubes that receive and maintain alignment of the bags, a restraining jaw for restraining the stack of bags on the tubes and a pusher plate for pushing the stack of bags off the two tubes.
摘要:
A method of manufacturing polymer-coated particles is useful for chemical mechanical polishing magnetic, optical, semiconductor or silicon substrates. First it provides a dispersion of particle cores in a non-aqueous solvent. Then introducing a polymeric precursor into the dispersion to react the polymeric precursor forms a polymer. The polymer coats at least a portion of the surface of the particle cores with the polymer and forms the polymer-coated particles having a solid outer polymeric shell. Substituting the non-aqueous solvent with water forms an aqueous mixture containing the polymer-coated particles. And it forms an aqueous chemical mechanical polishing formulation with the polymer-coated particles without drying the polymer-coated particles.

The polishing composition is suitable for chemical mechanical polishing magnetic, optical, semiconductor or silicon substrates. The polishing composition includes abrasive particles in a liquid media. The abrasive particles have a particle core, the particle core having a hardness and a polymeric shell physisorbed to and encapsulating the particle core. The polymeric shell has a solid structure and a hardness lower than the hardness of the particle core. The abrasive particles have an average particle size of less than or equal to about 2 micrometers dispersed in the liquid media.
