An illuminator includes a light guide having a light source that is configured to emit light along a length of the light guide. The light guide further includes outcoupling zones affixed to a rear portion of the light guide, each zones affixed a predetermined distance from each other zone, which are configured to direct at least a portion of the emitted light. The light guide also includes a first diffuser that corresponds to a front portion of the light guide, and which operates to diffuse emitted light exiting the front portion of light guide. The illuminator further includes a secondary diffuser that is located a predetermined distance from the front portion of the light guide forming an air gap there between. The secondary diffuser is configured to further diffuse the at least a portion of the emitted light diffused by the first diffuser after passage through the air gap.

An integrated device enables a customer replaceable unit used within an ink jet printer to be enclosed within an enclosing structure as the unit is removed from the printer. The enclosing structure traps debris that may disburse from the customer replaceable unit as it is removed from the printer. The integrated device includes an extendable cover that encloses the customer replaceable unit in response to one end of the cover being moved away from the other end.

The enclosing structure traps debris that may disburse from the customer replaceable unit as it is removed from the printer. The integrated device includes a customer replaceable unit that is mountable within a printer, a handle mounted to and extending from one end of the customer replaceable unit; and an extendable cover having a first end and a second end, the first end of the extendable cover being coupled to the handle and the second end of the extendable cover being configured to couple to a stationary structure within the printer, the second end of the cover being configured to extend past the customer replaceable unit in response to the first end of the cover being moved away from the second end and to be proximate to the first end to expose the customer replaceable unit in response to the first end of the cover being moved towards the second end.

摘要:
An organic coating composition is described, which can be used to enrich the surface region of a metal-based substrate with aluminum. The composition comprises an aluminum-based powder and at least one organic resin, e.g., alkyds, epoxies, or silicone materials. At least some of the aluminum-based powder is in the form of substantially spherical powder particles. The coating composition is substantially free of hexavalent chromium. It can be applied to the substrate by a variety of techniques, such as spraying. It is then heat-treated, to cause diffusion of aluminum into the surface region of the substrate, e.g., a turbine engine component. The composition exhibits good thermal and chemical stability for extended periods of time. Related articles are also described.

摘要:
A slurry coating composition is described, which is very useful for enriching the surface region of a metal-based substrate with aluminum. The composition includes colloidal silica and particles of an aluminum-based powder, and is substantially free of hexavalent chromium. The slurry may include colloidal silica and an alloy of aluminum and silicon. Alternatively, the slurry includes colloidal silica, aluminum or aluminum-silicon, and an organic stabilizer such as glycerol. The slurry exhibits good thermal and chemical stability for extended periods of time, making it very useful for industrial applications. Related methods and articles are also described.
