    摘要: A stable colored liquid developer and method for making such are described wherein an improved optical density resulting from a colored dye being imbibed into a thermoplastic resin core occurs. In particular, the liquid developer comprises a marking particle dispersed in an aliphatic dispersion medium, the marking particle comprises a thermoplastic resin core having an amphipathic block or graft copolymeric steric stabilizer irreversibly chemically or physically anchored to the thermoplastic resin core with the dye being imbibed in the resin core and being soluble therein and insoluble in the dispersion medium. The stable colored liquid developer is preferably made by first preparing a graft or block copolymer amphipathic steric stabilizer, anchoring said stabilizer to a thermoplastic resin core, and to the aliphatic disperion of said particle adding a solution of a dye dissolved in a polar solvent, preferrably methanol, the dye being soluble in the thermoplastic resin core to enable it to be imbibed therein and substantially insoluble in the dispersion medium.

    摘要: An electrophoretic display device which provides high contrast images and a stable suspending fluid is described. A white marking material such as titanium dioxide is suspended in a colloidal dispersion containing black colorant such as colloidal size iron oxide particles known as ferrofluids. Image formation is achieved electrophoretically by selective application of an electric field across the imaging suspension.

    摘要: A flapper valve includes a valve body having a hinge member. A flapper is pivotally mounted to the valve body through the hinge member. At least one of the valve body and the flapper includes a multi-stage valve seat. The multi-stage valve seat includes a first sealing zone and a second sealing zone that is distinct from the first sealing zone. The first sealing zone is configured to provide pressure containment at the valve body when the flapper is exposed to a first pressure and the second sealing zone is configured to provide pressure containment at the valve body when the flapper is exposed to a second pressure that is greater than the first pressure.
