Wear-resistant coating systems suitable for protecting surfaces subjected to contact wear at high temperatures, such as surfaces of an assembly comprising high-temperature components of gas turbine engines. The components have surfaces in wear contact with each other. One of the surfaces has a wear-resistant coating system thereon so as to be in wear contact with the surface of the other component. The wear-resistant coating system contains alternating layers of TiAlN and CrN.

High-temperature jointed assemblies and wear-resistant coating systems therefor

An invention is disclosed in which a fluidic counter generates fluidic switching signals in response to a fluidic oscillator for sequentially activating a plurality of fluidically activated electrical switches for multiplexing a plurality of electrical conductors into a single conductor.

Pneumatic signal multiplexer

A switch is disclosed having a plurality of conductors entering a chamber containing a movable contact element. Air pressure applied to the contact element moves it into contact with at least one of the conductors.

Pneumatic ball contact switch

An invention is disclosed wherein one portion of conductor is fastened to a housing and another portion is movable. Fluid pressure applied through a passage forces the movable portion into contact with electrical terminals.
