Abstract: A service station for use in servicing one or more inkjet print cartridges includes a service station sled assembly movably attached to a service station chassis. In one embodiment, the service station includes a sled assembly that includes a cap for enclosing a printhead of a print cartridge, a sled carrier on which the sled assembly is positioned, a cam follower structure including a cam follower, a cam positioned to interact with the cam follower, a mechanism for compliantly attaching the cam follower structure to the sled carrier, and a motor adapted to move the cam. The mechanism for compliantly attaching provides a compliant support for the sled assembly that enables the sled assembly to be positioned in a capping position that ensures adequate contact between the cap and printhead, but that alleviates excessive forces that may otherwise build up between the sled assembly and the print carriage during capping as a result of moving the sled assembly too far in a direction toward the printhead.

Abstract: A multiple-function printing device provides for picking pages from a stack of sheets in an input feeder for roller-driven movement along a first path through a printing station to an output, and for picking pages from a stack of documents in an input feeder for roller-driven movement along a second path through a scanning station to an output, with at least a portion of the first and second paths being commonly shared, with a document deflector which, in a document scanning mode of operation, is pivoted into a lowered position generally parallel to a print station platen to constrain the top and bottom of curled documents exiting from the scan station so as to prevent an incipient paper jam. The deflector is actuated by a drive mechanism including a ball link and cranks connected to a common motor in a service station for capping and wiping print cartridges in the printing station.

Abstract: A compressor with a rotary driven centrifugal impeller which receives inlet air from an inlet passageway and this discharges compressed air through a radially extending diffuser passageway. Moveable vanes are provided both in the inlet passageway and diffuser passageway for varying the pressure and flow output from the compressor while maintaining the rotary speed of the centrifugal impeller substantially constant. In the preferred form of the invention, the centrifugal impeller and an electrical generator are rotatably driven at a constant speed and in synchronism with each other and, together, form an electrical and pneumatic power system.

Abstract: A record player turntable has a substantially flat circular metallic top and an integral substantially cylindrical downwardly extending metallic flange and a resilient mat having a circular top portion covering the aforesaid circular metal top portion and having an integral downwardly extending resilient flange gripping the said metallic flange. The connection between the horizontal metal turntable top and its connected vertically extending flange consists of an integral diagonal web of the metallic flange flared downwardly and outwardly. This web has grooves providing for a lodgment and gripping action on the part of the circular downwardly extending rim of the inverted pan-shaped plastic mat that covers the turntable top and it also forms part of the exposed substantially cylindrical lateral face of the turntable.

Abstract: A pin mounted on the under side of a turntable is used to hold a drive belt also engaged by a drum which is mounted on the turntable and forms a loop. Mounted on a base plate is a drive pulley. This invention solves the problem of how to assemble the turntable on the base plate and end up with the belt engaged on the pulley and the drum. During assembly the turntable is placed over the base plate with the pulley inside the loop. A simple turning of the turntable will cause the belt to tension and slip off the pin onto the pulley.
