Abstract: A hearing protection device is provided. The hearing protection device includes a first earmuff connected to a second earmuff by a headband. Each of the first and second earmuffs are configured to dampen ambient sound. The hearing protection device also includes an antenna, located within a housing of the first earmuff. The antenna comprises a rigid portion coupled to a flexible portion. Both the rigid portion and the flexible portion are fixed within the housing. The flexible portion is configured to remain substantially in line with a ground plane with respect to the rigid portion.

Abstract: A method, rotor assembly, and apparatus for ordering blades in a rotatable machine is provided. The rotor assembly includes a disk including a plurality of circumferentially-spaced blade root slots defined therein, and a plurality of blades, each blade including a root, a tip, and an airfoil therebetween, each blade positioned within a pre-determined slot based on a blade map, the blade map generated by a computer system configured to receive a geometric parameter measurement of each blade in a row of blades, determine a shape factor for the row of blades using the geometric parameter measurement of each blade, and determine a sequence map of each blade using the shape factor for the row of blades.

Abstract: A rotator member, for example an airfoil of a rotating blade, is provided with additional stiffness in a radially outer portion of the member by including in the outer portion at least one corrugation extending generally along the width, for example chordwise, of the member.

Abstract: An aircraft engine thrust mount includes a pair of spaced apart thrust links pivotally joined at one end to an engine first frame and at opposite ends to a lever. A platform is fixedly joined to an aircraft pylon and includes first and second spaced apart clevises and a center clevis therebetween. The center clevis is pivotally joined to a center of the lever for carrying thrust force from the first frame through both thrust links and to the platform and pylon during normal operation. A pair of pins pivotally join the thrust links to the lever and extend through apertures in the platform first and second clevises to define predetermined gaps therebetween for allowing the lever to rotate relative to the platform center clevis up to a predetermined angular rotation. In a failure mode of operation the pins contact the platform first and second clevises for transmitting thereto either tension or compression thrust loads for providing an alternate failsafe loadpath.

Abstract: A gage for indicating the runout condition of a valve seat edge formed by and between adjacent surfaces of a valve seat adjacent one end of a valve guide bore and concentric with the axis thereof, the valve guide bore accommodating an elongated pilot member that extends therefrom through the valve seat surfaces. The gage comprises a housing member adapted to be mounted on the pilot member in fixed spaced relationship from the valve seat and having a dial indicator mounted thereon at a location spaced radially from the pilot member, and a work engaging member mounted for rotatable and axial movement on the pilot member in the space between the housing and the valve seat. The dial indicator has a plunger member extending therefrom substantially parallel to the pilot member and an indicator needle operatively connected to the plunger member and movable in response to movements of the plunger member to produce a visual indication as to the position of the plunger member.

Abstract: A carburetor improvement comprises a flow passage through which fuel vapors created in a fuel bowl are drawn off to a chamber having a first outlet through which fuel vapors are directed to a canister and a second outlet through which fuel vapors are directed to an air passage in the carburetor. A solenoid includes a valve member movable between a first position opening the first outlet and closing the second outlet and a second position closing the first outlet and opening the chamber outlet. The valve member is moved to its first position when the engine is off so fuel vapors are collected in the canister and to its second position when the engine is operating so fuel vapors are directed to the air passage.
