Abstract: In one embodiment, a monolithic array of particle separators is described that is formed as a single component using an additive manufacturing process. The array may be used as building blocks to generate any sized array of inlet particle separators for jet engines (e.g., a gas turboshaft engine for a helicopter) as desired. If damage occurs to the inlet array during operation of the engine, the modular construction of the inlet array enables the damaged block(s) to be replaced with new blocks, thereby reducing downtime of the aircraft.

Abstract: A novel neon lighting protective mounting device comprised of a transparent elongated elastomeric tubing or sleeve having two parallel interior channels which are able to seat both the central light emitting portion of a neon border light as well as the terminal blackened bent portions of a neon border light. The protective tube further has a flat surface extending its length which allows maximum illumination of the central light emitting portion of the neon border light through the transparent tube and which also allows the protective tubing to be removably mounted to the interior surface of a store window by using Velcro strips, screw and eyelet mounts or other type of attachment device.
