Abstract: A steel armour comprising between 90% and 50% bainite, the rest being austenite, in which excess carbon remains within the bainitic ferrite at a concentration beyond that consistent with equilibrium; there is also partial partitioning of carbon into the residual austenite. In one embodiment of the invention the bainite comprises in weight percent: carbon 0.6 to 1.1%, silicon 1.5 to 2.0%, manganese 0.5 to 1.8%, nickel up to 3%, chromium 1.0 to 1.5%, molybdenum 0.2 to 0.5%, vanadium 0.1 to 0.2%, balance iron save for incidental impurities. In particular it was noted that excellent properties were obtained if the manganese content is about 1% by weight. By forming the steel as a pearlite sheet the elements (310,410) of the panel can be formed easily by cutting or stamping before final transformation to bainite. Cutting may also occur after final transformation using water- jet or laser cutting. Alternatively hot forging elements is described.

Abstract: A system for tailoring a transfer nip electric field includes a transfer roll, a backup roll forming a transfer nip with the transfer roll, and a pre-nip roll positioned upstream from the transfer and backup rolls and the transfer nip such that a toner image-supporting transfer belt moving past the pre-nip, transfer and backup rolls separately makes contact with, wraps partially around, and rotates each of the rolls as a media sheet is fed into the transfer nip after first passing through a gap defined between the pre-nip and transfer rolls such that by presetting the position, geometry and charge of the pre-nip roll relative to the transfer and backup rolls and the transfer belt an electrical field at the transfer nip can be tailored for enhanced toner transfer from the transfer belt to the media sheet.

Abstract: An image forming apparatus includes a plurality of photoconductive drums, each photoconductive drum transferring a portion of a toner image to an intermediate transfer member. The photoconductive drums are individually rotated to a printing speed such that a downstream photoconductive drum starts rotating prior to an adjacent upstream photoconductive drum starts image transfer. Similarly, an upstream photoconductive drum starts deceleration when its following downstream station has transferred image.

Abstract: An intermediate toner transfer belt includes an endless member made of a layer of a material having an endless functional surface adapted to transfer a toner image. The layer of material is textured so as to define a multiplicity of protruding portions of the material spaced apart from each other and integral with and extending outwardly from a remaining base portion of the material. The protruding portions have outer tips spaced apart from one another with outer surfaces thereon also spaced apart from one another such that the endless surface of the endless member is formed by the spaced apart outer surfaces of the outer tips of the protruding portions of the material. Further, the protruding portions are irregular in pattern and shape relative to one another and generally undulate toward and away from the remaining base portion of the material.

Abstract: A device and method for determining and applying a transfer voltage in an imaging apparatus is provided. A servo voltage is determined based in part upon a change in an environmental condition. A determination is made whether or not to perform a new transfer servo operation based upon at least one of an amount of time passing since the last transfer servo operation was performed and a comparison of the determined servo voltage and a servo voltage used in a prior transfer servo operation. A transfer servo operation includes charging a photoconductive drum to a charge corresponding to a printing voltage.

Abstract: Super Bainite Steel is described comprising between 90% and 50% bainite, the rest being austenite, in which excess carbon remains within the bainitic ferrite at a concentration beyond that consistent with equilibrium; there is also partial partitioning of carbon into the residual austenite. Such bainite steel has very fine bainite platelets (thickness 100 nm or less). In this specification the expression “Super Bainite Steel” is used for such steel. In particular, the impact of varying the manganese content to achieve fast transformation times, and hence low manufacturing costs without the presence of expensive alloying materials is discussed. In one embodiment of the invention a Super Bainite Steel comprises in weight percent: carbon 0.6 to 1.1%, silicon 1.5 to 2.0%, manganese 0.5 to 1.8%, nickel up to 3%, chromium 1.0 to 1.5%, molybdenum 0.2 to 0.5%, vanadium 0.1 to 0.2%, balance iron save for incidental impurities.

Abstract: The present application is directed to devices and methods for removing toner from a belt within an image forming apparatus. In one embodiment, the device includes a housing that forms an enclosed interior space. The housing may include an inlet that leads into the interior space. A blade may be positioned in proximity to the inlet to remove the toner from the belt and direct it into the inlet. An auger may be rotationally positioned within the interior space to move the toner along a longitudinal width of the device. An agitating member may be rotationally positioned within the interior space to move the toner from the inlet towards the auger. The agitating member may include a flexible arm that contacts against at least one of the blade and the auger during rotation.

The outer surface layer may be formed of a polyurethane elastomer material to provide a capacitive coating with a thickness greater than 15 microns, a dielectric constant less than 12 and a resistivity of less than 3.00E+13 Ohm-cm.

Abstract: A method and system for detecting a transfer of an endpoint device are disclosed. For example, the method receives an indication of a transfer of an endpoint device to a new user by a service provider. The method then notifies a subscriber associated with the endpoint device that the indication of the transfer was received by the service provider.

Abstract: A lamp (10) includes a housing (12) with a light source (30, 32) disposed within the housing. Two or more light modulating elements (80, 82, 84, 86) are associated with different components of the lamp, such as a reflector housing (70), an envelope (36), a lens (74), and a shroud (76). Each of the light modulating elements modulates the visible light emitted by the source intermediate the source and an exterior of the housing. One of the light modulating elements modulates light in at least one region of the visible portion of the electromagnetic spectrum differently from another of the light modulating elements. In this way, the light emitted by the source may be tailored by using different properties of each of the light modulating elements.
