Abstract: An anti-corrosive coating composition is disclosed. The anti-corrosive coating composition includes a binder, an electrically conducting polymer, one or more fillers, and a crosslinker. The electrically conductive polymer may include polyaniline, poly(3,4-ethylenedioxythiophene), polypyrrole, or an additive, such as a biopolymer grafted thereto. A method for making an anti-corrosive coating composition is also disclosed.

Abstract: A shuttle valve including a first inlet having a first, substantially uniform fluid line and a second inlet having a second, substantially uniform fluid line. A manifold chamber is in communication with the first and second fluid lines, and an outlet having a third fluid line between the first and second inlets. The third fluid line has a third inner radius substantially uniform along a third length of the third fluid line. A spool is disposed in the manifold chamber. A retention feature is disposed in the manifold chamber and configured to retain the spool at one of a first position and a second position. At the first position the spool blocks the first inlet; at the second position the spool blocks the second inlet, but the outlet remains open. The first inlet, the second inlet, the outlet, and the manifold chamber are integrally formed as a monocoque body.

Abstract: A stowage bin assembly and method of operation includes a front panel configured to be selectively switched between a transparent mode and an opaque mode, a baggage retaining chamber defined, at least in part, by the front panel. The front panel is moveable between an open position and a closed position. The front panel can be further configured to be selectively switched to a translucent mode.
