Abstract: A method of manufacturing an inkjet printer component and an inkjet printer component electropolishing device are provided. The method includes positioning an electrode in a fluid passageway of an inkjet printer component, the electrode including a conductive face and a nonconductive face; polishing a side of the fluid passageway by: biasing the nonconductive face of the electrode toward a side of the fluid passageway such that the conductive face of the electrode does not contact any portion of the fluid passageway; providing an electrolytic fluid to the fluid passageway of the inkjet printer component; and applying a voltage between the electrode and the inkjet printer component.

Abstract: A method and apparatus are provided for removing contaminates from ink jet printer components. The normal output from a Nd-YAG laser is frequency multiplied to be capable of removing particulates and films from ink jet printer components. The laser cleaning technique provides a dramatic effect on yields.

Abstract: Metallic bumps are formed for electrical interconnection between the charge plate and the charge drive electronics. This is achieved by having improved electrical connection between an ink jet charge plate and associated charge leads is promoted. This is achieved by integrating the termination pads, electrical transmission lines, and charging leads. The termination bumps are formed as integral parts of the charge leads and are connected directly to the charge driver board electronics by pressure contact. The bumps can be formed by mechanically indenting the termination pads or by using an interposer that has raised metallic pads aligned to the integral nickel pads and the charge driver circuitry board. First, a mask is aligned to permit additive formation of the pads, conductors, and charge leads. Then the nickel circuitry thus formed is made into a rigid charge plate and an integrated flexible section having contact bumps.

Abstract: An apparatus including an elongate housing formed with a funnel entrance and an exit door utilizing springs mounted on opposed sides of the housing to bias the door in a first closed position when the door is displaced relative to a foward or second portion of a top wall to provide access to an interior cavity of the housing. The housing includes a counterweight mounted medially to the bottom surface of the bottom wall of the housing, including plural pairs of spring legs to mount and permit entrenching of the minnow housing within a level or soil laden bottom support surface of a stream, lake, and the like.

Abstract: An apparatus for continuously mixing dust and water for disposal of the dust, the apparatus including a vertical pipe with a removable cover at its upper end, an inlet pipe adapted to deliver dust particles into the vertical pipe, a mixing chamber closed at the upper end except for the lower end of the vertical pipe discharging thereinto, the lower end of the chamber being open and submerged in a pool of water, water inlets adjacent to the upper end of the chamber directing water tangentially over the walls of the chamber, a water inlet into the pool of water, and an overflow outlet from the pool to remove a mixture of dust and water from the apparatus. A process which includes classifying ash particles from an industrial boiler, passing the smaller particles into an enclosed zone with water washing the walls of the zone and the bottom of the zone opening underneath the level of a pool of water which overflows to discharge a mixture of water and dust for disposal.

Abstract: Improvements in well bore centralizers; improvements in centralizers which may be shipped by the manufacturer unassembled, occupying a small volume of space, and later assembled; a field-assemblable casing centralizer consisting of a pair of collars and connecting outwardly bowed leaf springs secured to the collars by a cooperating leaf spring end and collar structure and relief thereof permitting both rivet and weld attachments.
