  • Patent number: 8696322
    Abstract: An automatic deactivation mechanism is configured for an air bladder pump having a casing and a motor located therein to pump air into an air bladder from the atmosphere and through an air valve connected through the casing. The automatic deactivation mechanism includes a housing positioned within the casing and has defined therethrough a first aperture in fluid communication with the atmosphere through the casing and a second aperture in fluid communication with the air bladder through the casing. Included within the housing are at least two switches and a diaphragm positioned between the switches. The housing is sealed so that when a threshold pressure is reached therein, at least one switch is triggered by deflection of the diaphragm to automatically deactivate the pump by de-energizing the motor.

  • Patent number: 7645564
    Abstract: The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.

  • Publication number: 20080090167
    Abstract: The present invention relates to a method for combining extra particulate additive with toner. The method includes mixing toner and extra particulate additive in a conical mixer having temperature control. The toner may contain polymeric material having a glass transition temperature (Tg) and the mixing may be carried out wherein the temperature of the mixture is maintained at a temperature less than Tg. The above method may also be applied to a toner formulation that has first undergone a rounding operation.

  • Patent number: 7337392
    Abstract: A method is disclosed to generate, while preserving text, image, transactional and embedded presentation constraint information, a minimum set of simplified and navigable web contents from a single web document that is oversized for targeted smaller devices. The method includes a parser, a content tree builder, a document tree builder, a document simplifier, a virtual layout engine, a document partitioner, a content scalar and a markup generator. The parser generates markup and data tags from an HTML source document. The builder constructs a content tree. The simplifier transforms the document tree into an intermediate one defined by a subset of XHTML tags and attributes. Layout constraints, including size, area, placement order, and column/row relationships, are calculated for partitioning and scaling the document tree into sub document trees with assigned navigation order and hierarchical hyperlinks. A simplified HTML document is then generated with the markup generator.

  • Patent number: 6991886
    Abstract: Toner is rounded by vigorously mixing less than about 5 percent by weight of particulate silica to the total weight of a starting toner in a closed, recirculating air system. The starting toner contains at least about 4.5 percent by weight of the starting toner of a wax and additionally contains at least 5 percent by weight of the starting toner of a softening agent. The temperature during the mixing is no more than 13 degrees C. above the onset of the glass transition temperature of the starting toner. The final toner comprises rounded starting toner having particulate silica embedded during the mixing process.

  • Patent number: 6984935
    Abstract: A method for molding and aligning microstructures on a patterned substrate using a microstructured mold. A slurry containing a mixture of a ceramic powder and a curable fugitive binder is placed between the microstructure of a stretchable mold and a patterned substrate. The mold can be stretched to align the microstructure of the mold with a predetermined portion of the patterned substrate. The slurry is hardened between the mold and the substrate. The mold is then removed to leave microstructures adhered to the substrate and aligned with the pattern of the substrate. The microstructures can be thermally heated to remove the binder and optimally fired to sinter the ceramic powder.
