Abstract: A seat assembly for task-oriented seating comprises a seat support and a seat coupled to the seat support. The seat is movable under load, such as from the user's weight and movements, relative to the seat support. The seat has a cushion molded over a supporting armature with multiple bias elements. The seat and seat support are configured to deflect by predetermined amounts at defined locations over an extent of the seat assembly. In this way, the seat assembly provides for a range of comfortable and effective positions for users engaged in different active motions and having different preferences and sizes.

Abstract: A rotatable printing machine includes a horizontal exchangeable cylinder which is held between two sidewalls of a machine frame by a holding and driving arrangement which enables disengagement. To remove the cylinder, a carriage arrangement is positioned in the frame and can include a movable trolley for receiving the cylinder and sliding it in a horizontal plane onto a hand cart. One embodiment includes a movable table for raising and lowering the cylinder from the path of the trolley to the operating position. Another embodiment positions rails for the trolley immediately underneath the operating position of the cylinder and includes an arrangement for raising and lowering supports for the cylinder relative to the cylinder. A third embodiment includes a fixed track mounted immediately adjacent the cylinder and utilizing position adjustment means for the drives of the cylinder to lower the cylinder onto the track.

Abstract: A device for conveying a sheet of material from one printing unit to a second printing unit consisting of a frame having horizontal lateral beams, a plurality of cross-shafts extending between the beams, each shaft being provided with a plurality of axially-spaced rollers, a plate being mounted on a lower surface of each of the lateral beams having apertures arranged to allow a lower portion of each roller to extend therethrough and an arrangement for applying a suction to the interior of the frame to draw air in the gap between each aperture and roller to hold a sheet against the rollers as it is conveyed from one unit to the next.
