Abstract: Multilayer optical film comprising at least a plurality of alternating first and second optical layers. Embodiments of the multilayer optical film are useful, for example, in UV-C shield, UV-C light collimator, and UV-C light concentrator applications.

Abstract: A light guide comprising a polymeric layer at least 25 percent transmissive over at least a 30 nm bandwidth in a wavelength range from 180 to 280 nm over a distance of at least 100 micrometers and visible light transparent reflecting layers (UV-C mirror) that are at least 50 percent reflective over at least 30 nm bandwidth in a wavelength range from 180 to 280 nm over an incident light angle of 0 to 90 degrees and that are at least 25 percent transmissive of visible light over at least 30 nm bandwidth in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees. The light guide is useful, for example, for antimicrobial surfaces.

Abstract: The present disclosure is directed to an illumination and imaging system, which may comprise a housing, a transflective element, a light source, and an optic apparatus. The housing may have a cavity with an opening. The transflective element may be substantially aligned with the opening. The light source may be disposed within the cavity. The optic apparatus may also be disposed within the cavity and have a collimator optic and a spreader optic. The collimator optic may be configured to collimate light emitted from the light source toward the transflective element. The spreader optic may be disposed proximate the transflective element and configured to transmit and spread the collimated light for transmission through the transflective element to substantially illuminate the vehicle interior.

Abstract: A robust fastener locking device (10, 20) prevents loosening of a fastener (F) used to attach to two parts (P1, P2) together. A plate (12, 22) fits against a part and abuts against at least two adjacent sides (S1, S2) of the part. The plate has an opening (14, 24) therein sized for a bolt to be inserted through the opening with the head of the bolt, or the nut (N) bearing against the plate when the fastener is secured in place. A portion of the plate adjacent the opening is deformable about the fastener after the fastener is secured in place to prevent subsequent rotation of the fastener which would loosen the fastener. In one embodiment, tabs (30a-30c) are formed adjacent the opening and can be bent about the portion of the fastener. The tab is broken off if the fastener needs to be removed, but the locking device can be reused.

Abstract: A nozzle box includes first and second nozzle box halves which are bolted together. Each nozzle box half includes a nozzle ring segment that carries nozzles along its entire 180° arc, so that when the nozzle box halves are joined together a nozzle box is formed with no discontinuities of nozzles around its 360° circumference. The nozzles carried on each nozzle ring segment communicate with inlet ports, and associated passages which are perpendicular to the nozzle box exit plane.

Abstract: A process for replacing a multi-piece steampath in a nozzle box (12) where, initially, the steampath (22) is secured between upper (24) and lower (26) ring components by means of axially accessible, arcuate welds (36, 38) includes the steps of:a) axially machining the arcuate welds (36, 38) so as to permit removal of the steampath (22) in a direction axially away from the nozzle box;b) further machining a forward portion of the lower ring component to provide a substantially vertical weld surface; andc) securing a one-piece steampath (222) in place by an axially accessible upper weld (236) and a radially accessible lower weld (238).
