  • Patent number: 7470901
    Abstract: A charged particle (e.g. photoelectron) spectrometer is operable in a first mode to produce an energy spectrum relating to the composition of a sample being analysed, and in a second mode to produce a charged particle image of the surface of the sample being analysed. A detector is used to detect charged particles produced in both modes of operation. A method of operation of the spectrometer includes the step of selecting which of said first and second modes to use and the detector being operated accordingly.

  • Publication number: 20080014525
    Abstract: A method of forming a xerographic image having at least one portion with a gloss different from a gloss of another portion of the xerographic image includes xerographically forming a toner image on a surface of a substrate and forming a finish over the toner image at the at least one portion, the finish being made of a differential gloss finish coating material that has a gloss different from that of the toner image. The differential gloss finish coating material is preferably an emulsion aggregation toner that is substantially free of pigments that adversely affect the transparency of the toner following fusing, the toner having gloss tunability through control of the amount of crosslinked portions included in the toner.

  • Publication number: 20060089038
    Abstract: A quick release connector is provided. In one embodiment the connector includes an electrical connector including a first component having a first plurality of teeth and a second component having a second plurality of teeth. The first and second pluralities of teeth are configured to selectively engage and disengage one another upon connecting and disconnecting the connector. The engagement of the teeth is operative to substantially prevent relative axial motion between the first and second portions of the connector. Embodiments of this invention may advantageously support axial loads while maintaining a reliable electrical contact. Various alternative embodiments include a gimbal assembly in which electric lines extend through the gimbal, straddling one of the gimbal axles. Such gimbal assemblies may also support axial loads.

  • Publication number: 20050255402
    Abstract: A process involving heating a mixture of a colorant dispersion, a latex emulsion, and an optional wax dispersion in the presence of a coagulant containing a metal ion, a base, and an organic sequestering agent, and wherein said heating involves a first heating and a second heating, and wherein the second heating is at a higher temperature than the first heating; and wherein said higher temperature is equal to about or above about the Tg of polymer or resin contained in said latex emulsion.

  • Publication number: 20050176853
    Abstract: A process including blending a latex emulsion of resin, water, and an ionic surfactant, a colorant dispersion comprised of a colorant, water, and an ionic surfactant; and a wax dispersion comprised of wax, water and an ionic surfactant, heating the resulting mixture in the presence of coagulants, one of which is a source of calcium ions, which heating is below about the glass transition temperature (Tg) of the latex resin and subsequently heating above about the glass transition temperature (Tg) of the latex resin.

  • Publication number: 20050051406
    Abstract: A support assembly is provided for suspending lightweight tools or other objects, such as hairdryers and the like. The assembly provides support and in particular embodiments, electrical power to the object suspended. In addition, the assembly provides management of the power cord. Embodiments of the assembly include a quick release electrical connector deployed between and configured to selectively electrically connect and disconnect the tool from a power supply and/or a gimbal assembly configured to permit rotation of the tool about first and second axes, the cord extending through the gimbal assembly.
