摘要： A dampening fluid useful in offset ink printing applications contains water and a surfactant whose structure can be altered. The alteration in structure aids in reducing accumulation of the surfactant on the surface of an imaging member. The surfactant can be decomposed, switched between cis-trans states, or polymerizable with ink that is subsequently placed on the surface.

摘要： A non-atmospheric pressure vapor oven system that utilizes a controllable pressure zone to facilitate fast phase change heat transfer at any desired temperature to heat or cool flat substrates, and to level temperatures across different locations of the substrates. The system enables the use of a heat transfer fluid, such as water, without being limited to a particular temperature, such as the fluid's natural boiling point at atmospheric pressure. The system includes a vapor oven (hermetic enclosure) defining a pressure chamber having sealed entry and exit ports for transferring an object (e.g., a sheet of paper) with added material (e.g., toner) through the pressure chamber, and a pressure regulation apparatus for setting the saturation temperature (boiling point) of heat transfer fluid inside the vapor oven to an optimal heating/cooling temperature by selectively controlling the pressure inside the hermetic enclosure.

摘要： Substrate (or marking material) pre-heating is employed to facilitate fusing of the marking material with the substrate and with adjacent marking material. By heating primarily the material which becomes the interface between substrate and marking material, and by minimizing the distance between the point of heat application to the substrate (or marking material) and the marking nip in a print system, the amount of time for heat energy to dissipate prior to the application of the marking material to the substrate surface is minimized, meaning that the total amount of energy required to drive the heat source can be reduced. Addressable heating may be employed to further reduce energy consumption. Furthermore, optical heating may be used to provide rapid, on-demand heating, thereby reducing warm-up time as well as reducing unutilized heat energy.

摘要： A dual-zone steam fuser for a xerographic system includes a ultra-heated first zone maintained at 200-500° C. that quickly heats a paper substrate to an optimal toner fusing temperature (e.g., 120-150° C.), and a second, relatively cool second zone for maintaining the substrate at the optimal temperature during completion of the fusing process. A conveying system conveys the substrate so that it exits the first zone and enters the second zone immediately after the substrate temperature reaches the optimal toner fusing temperature, and is maintained in the second zone for a predetermined fusing operation time period. The gas (e.g., steam) temperatures and timing are selected such that surface condensation is minimized during initial heating, and such that moisture content is normalized at the end of the fusing process.

摘要： An improved microvalve is described. The microvalve includes a corresponding actuation aperture in an actuation aperture layer. A control fluid flows through the actuation aperture. The flow of the control fluid is controlled by an electric field typically applied via a charge distribution near an actuation aperture layer. In one embodiment, the electric field may adjust the opening and closing of the actuation aperture thereby controlling the flow of the control fluid. In a second embodiment, the control fluid is an electrorheological fluid where the electric field controls the viscosity of the ER fluid thereby controlling fluid flow through the actuation aperture. In both embodiments the flow of the control fluid controls stretching of a flexible membrane formed along the wall of a conduit through which a fluid to be controlled flows.

摘要： A method of controlling a main fluid in a conduit using a microvalve is described. The microvalve includes a corresponding actuation aperture in an actuation aperture layer. A control fluid flows through the actuation aperture in response to an electric field applied via a charge distribution near an actuation aperture layer. In one embodiment, the electric field may adjust the opening and closing of the actuation aperture thereby controlling the flow of the control fluid. In a second embodiment, the control fluid is an electrorheological fluid where the electric field controls the viscosity of the ER fluid, thereby controlling fluid flow through the actuation aperture. In both embodiments the flow of the control fluid controls stretching of a flexible membrane into and out of the conduit, thereby controlling the flow of the main fluid by opening or closing the conduit.
