Abstract: An image transfer assembly includes a transfer belt formed as an endless loop around a backup roll and a tension roll. A tensioning arm is movably mounted on a side of a frame and operatively connects to an axial end of the tension roll such that the arm and axial end of the tension roll moves together relative to the frame. A translating member slidably mounted about the axial end of the tension roll is movable in an axial direction. A cam disposed below the translating member has an angled cam surface in contact with a portion of the translating member such that as the translating member moves in the axial direction, the translating member moves along the angled cam surface changing an elevation of the arm and axial end of the tension roll and changing an amount of skew of the tension roll relative to the frame.

Abstract: An ITM module for an imaging device, including a frame; a tension roll disposed in the frame; an ITM belt rotatably coupled to the frame and formed as an endless loop around rolls of the ITM module, including the tension roll; and an adjustment mechanism coupled to an end portion of the frame and to the tension roll, the adjustment mechanism setting an amount of skew of the tension roll relative to the frame. The amount of skew is in a direction that is substantially orthogonal to a process direction of the ITM belt. The adjustment mechanism includes a cam member rotatably coupled to the frame and having a cam surface coupled a first end portion of the tension roll such that rotating the first cam member sets an amount of elevation of the first end portion of the tension roll relative to the frame.

Abstract: An image forming device according to one example embodiment includes a housing having an access door manually movable between a closed position and an open position. A carriage is mounted on an inner portion of the access door. A first roll is rotatably mounted to the carriage and forms a nip with a second member positioned in the interior of the housing when the access door is closed. The first roll is spaced away from the second member when the access door is open. The carriage is free to move relative to the access door and is biased away from the access door toward the second member. A clamping assembly is configured to clamp the first roll against the second member to form the nip as the access door is closed and unclamp the first roll from the second member as the access door is opened.

Abstract: The present application is directed to toner transfer systems with an adjustable transfer belt. The transfer belt transfers toner images from a first location to a second location. Two or more support rolls position and drive the transfer belt. A tensioning device is operatively connected to one of the support rolls. The tensioning device moves the support roll between a first position that places a first amount of tension on the belt, and a second position that places a lesser second amount of tension on the belt. The support roll is in the first position during image formation, and in the second position during non-image formation such as storage and shipping.

Abstract: A rotary platform is provided for the harvest of specialty crops such as grass seed. In particular the conditioning rolls are removed from the header to reduce seed shatter and converging elements are added inside the conditioner opening on both sides and to the rear of the cutterbar to feed the crop around the conditioner opening corner and to the rear of the platform. Additional converging elements are provided behind the first converging elements at a angle less then 90 DEG. to the ground so as to form the top of the windrow so that there is minimal seed loss. The converging elements may or may not be powered and the angle of the second converging element can be adjustable. The rotary knives perform the cutting function more efficiently than a sickle cutterbar, and the converging elements move the crop toward the center to form a windrow with less disturbance.

Abstract: A crop knockdown shield is provided for use with rotary platforms in harvesting specialty crops such as grass seed. The knockdown shield is mounted to the front of the platform and extends forwardly and upwardly at an angle ahead of the cutting device. The knockdown shield can comprise two panels hingedly attached to one another so as to allow one panel to be folded back in shorter crops to improve visibility and to provide an extension of the first panel in higher crops. The knockdown shield serves to gently lean the crop forward before cutting so as to minimize seed shatter due whipping of the seed head.

Abstract: A cleaning apparatus in a waste toner removal system of an image forming device includes a waste toner moving device that is movably mounted in a waste toner housing. The housing has an inlet where waste toner enters the housing. The toner moving device is movable between a first position and a second position to displace accumulated toner within the housing. The toner moving device is spring-biased toward the first position. A rotating actuator displaces the toner moving device from the first position to the second position to move the toner in the housing away from the inlet. The toner moving device is also self-cleaning via vibration and impact movements.

Abstract: A direct-fired, propane powered steam generator is provided with a carburetor, which receives vaporized propane from a converter arrangement which converts liquid propane to vapor, receives pressurized air and feeds a mixture of vaporized propane and air into the combustion chamber of the steam generator. The amount of air delivered to the carburetor is variable, with the amount of vaporized propane entering the carburetor being determined by the position of a metering valve which varies in accordance with the amount of air passing through the carburetor. The converter arrangement receives liquid propane and is coupled to process water heated in the water jackets of the combustion chamber and adjacent structure, the converter arrangement being designed so that heat from the water is transferred for effecting vaporization of the liquid propane.

Abstract: A coating apparatus for applying a coating liquid to a printing substrate. The coating apparatus has a rotatable first roll and a rotatable second roll, each having a surface energy. The second roll is positioned adjacent to the first roll and defines with the first roll a first nip through which the printing substrate passes A metering device is provided for applying a substantially uniform layer of coating liquid onto the second roll. The second roll in turn transfers the coating liquid to the printing substrate. The surface energy of the second roll is greater than the surface energy of the coating liquid. In one embodiment, the metering device includes a rotatable third roll and a doctor blade contacting the third roll, each having a surface energy. The surface energy of at least a portion of either or both the third roll and doctor blade is less than the surface energy of the coating liquid.

Abstract: Substantially uniform spacing between a printhead and a platen throughout a print zone associated with said printhead in an ink jet printer is provided. The ink jet printer includes a printer frame, and the platen is slideably coupled to the printer frame. A first carrier guide rod is attached to the printer frame, and a second carrier guide rod has at least one end adjustably attached to the printer frame. A position of the second carrier guide rod is adjusted to provide parallelism between the first carrier guide rod and the second carrier guide rod. The platen is biased to a position relative to a position of at least one of the first carrier guide rod and the second carrier guide rod.

Abstract: The invention is directed to a concave for a rotary crop processing unit for an agricultural combine. The concave comprises a frame to which is releasably mounted a grid.
