    摘要: A spin-through rod centralizer consisting of a stator constructed of plastic, or other appropriate material, which is mounted on the rod coupling which provides the bearing surface for rotation of the coupling within the stator. The stator, which is free to rotate on the rod coupling and, hence, would move freely axially along the coupling, is restrained from such axial movement by two steel “washers” that are captured between the rod shoulders and the coupling when the connection between two rods is made up. The washers are slightly larger in diameter than the coupling and thereby keep the stator located on the coupling, yet do not restrict the relative rotation between the coupling and the stator. This coupling mounted centralizer will not interfere with rod string make-up when using equipment in common use. An alternative configuration uses a coupling with a shoulder at one end that acts as one of the “washers” to restrain the stator from axial movement.

    摘要: An ink jet printhead cartridge includes a cartridge body including a base and a plurality of side walls extending upwardly from the base. A filter tower having a tower wall has an interior surface that defines a location of a tower passageway. A printhead chip assembly is attached to the base of the cartridge body in fluid communication with the tower passageway. A filter is attached to the filter tower at a distal end thereof. An ink fill access port is formed through a side wall of the plurality of sidewalls, and through the tower wall of the filter tower, to define a fluid path from the atmosphere external to the cartridge body to the tower passageway of the filter tower to facilitate the injection of ink directly into the filter tower during an ink filling operation for the ink jet printhead cartridge.

    摘要: A mounting structure (34) for receiving a sensor (18) having a sensing portion (26) and a base portion (30) includes a substantially flat sheet of material (20) having a first surface (20a), a second surface (20b) opposite the first surface (20a), and an aperture (36). The aperture (36) is configured such that the sensing portion (26) of the sensor (18) is passable through the aperture (36), and the base portion (30) is not passable through the aperture (36), but instead rests on the first surface (20a). The mounting structure (34) also includes a pair of tabs (38) that extend in a downward direction away from the second surface (20b) of the sheet of material (20) and are configured to immobilize the sensor (18) within the aperture (36).
