Appl. No.:

13/088797

International Classification:

B41J 29/38

US Classification:

347 6

Abstract:

A method of performing maintenance on printheads of an imaging device includes the detection of at least one missing or defective inkjet in a printhead. A first pressure is applied to ink in printheads in which at least one missing or defective inkjet was detected. The first pressure is configured to discharge ink from the plurality of apertures in an aperture plate of the printhead to reestablish fluid continuity through the inkjet. A second pressure is applied to all of the printheads to be wiped. The second pressure is configured to form a convex meniscus at the plurality of apertures in the aperture plate of all of the printheads to be wiped. A single actuator is then operated to move one or more wipers into engagement with the printheads to be wiped. During wiping the convex meniscus is encountered by a wiper to lubricate a printhead and prevent the printhead from being damaged by wiping. The single actuator then retracts the one or more wipers from the printheads.

International Classification:

F23R 3/00
F02C 3/04
F02C 7/24

Abstract:

A heat shield panel for a gas turbine engine includes a substrate layer having a first substrate surface and a second substrate surface opposite the first substrate surface. The first substrate surface and the second substrate surface define a substrate layer thickness therebetween. One or more thermally protective coating layers are applied to the first substrate surface of the substrate layer. The one or more coating layers have a constant coating layer thickness and the substrate layer thickness tapers along an axial length of the heat shield panel.

Abstract:

A method of polishing an outer surface of a ceramic coated gas turbine engine component includes applying a rotating diamond brush to the outer surface. The brush is configured to achieve a uniform finish of 150 microinches RA or less over the surface. The brush contains diamond impregnated bristles, and is affixed to a rotary head of a robotic arm. A force sensing controller limits brush forces against the component. The component disclosed is a hot section turbine vane designed for directional control of high temperature, high-pressure combustion gases, but the method may be applied to other components utilized in similar aerospace applications. The polished coating provides an improved thermal barrier for maintaining structural integrity of the component in environments having temperatures ranging up to 2,000 degrees Celsius. The method limits abrasive removal of ceramic material to only 0.0005 to 0.00075 inch, and saves time and expense over past practices.
