Abstract: An airfoil for a gas turbine engine includes pressure and suction surfaces that are provided by pressure and suction walls extending in a radial direction and joined at a leading edge and a trailing edge. A cooling passage is arranged between the pressure and suction walls and extending to the trailing edge. The cooling passage terminates in a trailing edge exit that is arranged in the trailing edge. Multiple rows of pedestals include a first row of pedestals that join the pressure and suction walls. The first row of pedestals is arranged closest to the trailing edge but interiorly from the trailing edge thereby leaving the trailing edge exit unobstructed.

Abstract: In an exemplary embodiment of the invention, a dual test mechanism is presented for use in a circuit breaker. More specifically, the dual test mechanism includes a dual test button which comprises a single switch for testing both the AFCI and GFCI circuits of the breaker. The test mechanism includes a circuit board, which forms a part of the circuit breaker, and a test button assembly which includes a test button and signaling components which are electrically connected to the circuit board.

Abstract: A circuit breaker including a housing having a window, a line terminal and a load terminal, and a circuit trip assembly. The circuit trip assembly includes a rotatable cradle, a moveable armature latch and a pivotable trip support including a trip indicator. Upon the occurrence of a tripping condition in the circuit breaker, the trip indicator moves from a first position where it is not visible through the window to a second position where it is visible through the window.

Abstract: A visible trip indication arrangement for a circuit breaker. The visible trip indication arrangement comprises a viewing window forming a part of the breaker housing, the viewing window including indicia thereon that is readily or enhancedly visible when the circuit breaker has been tripped and essentially not visible when the circuit breaker is operating by way of a trip indicator that moves under and aligns with the viewing window when the circuit breaker is in the tripped condition. The trip indicator having a brightly colored surface, causes the indicia on the viewing window to be readily visible by way of the reflected light off a surface thereof.
