Abstract: The axle assembly has an elongated shaft that is connected to a mounting bracket. A first end of an arm is connected to the elongated shaft. The arm extends rearwardly from the elongated shaft and connects to a bearing bracket at a second end. The bearing bracket has a pair of flanges and a pin that passes through the flanges and is received within an opening of a rotatable arm. The rotatable arm is connected to an axle.

Abstract: A vehicle is provided with a chassis having a footprint, a load carrying structure, and a support assembly coupling the chassis and the structure. The support assembly is adapted to move the structure relative to the chassis between a stowed position and a deployed position outboard of the footprint of the chassis. A plurality of wheels is configured to roll on the support surface and a plurality of axles coupling the wheels to the chassis are provided. Each axle includes at least one spindle supporting an individual wheel for rotation on a spindle axis. A steering system is adapted to position the wheels between driving and rotation arrangements with respect to the chassis such that in the rotating arrangement each of the plurality of wheels rotate relative to the chassis whereby the chassis, the platform and the support assembly may rotate in unison about the steer axis.

Abstract: An internal coating on an internal passage wall exposed at a passage opening through an article external surface is protected from removal during repair of the article, including removal of at least a portion of an external coating, by a masking assembly disposed about the passage opening. The masking assembly comprises a masking member and a substantially flexible seal, substantially inert to a coating removal medium for the external coating. The masking member is shaped for disposition about the passage opening across a gap between the external surface and the masking member. The substantially flexible seal is disposed across the gap substantially to seal the gap.

Abstract: A method of measuring current in a pulse count positioning system is provided, wherein various motor conditions such as back up due to cogging and/or gear train affects are taken into account in measuring current pulses that are correlated with the position of an electric device such as an automotive accessory. The method generally includes measuring current flow through an electric motor at regular intervals, summing the current flow at a second interval, storing the summed current flow as a current pulse occurs, starting a new sum of the current flow, and comparing sums for a previous two sums after a maximum timeout. Accordingly, the method according to the present invention takes various motor conditions into account for a more accurate measurement of current pulses, which correspond with the position of the electric device.

Abstract: A method for applying, in a non-oxidizing atmosphere, a diffusion aluminide coating to a metallic surface of an article combines use of a relatively low aluminide coating temperature in the range of about 1650-1800° F. with a relatively high Al activity Al source material including Al of at least about 40 weight %. Such combination results in an as-deposited aluminide coating comprising a diffusion portion bonded between a metallic substrate and a coating outer portion of a thickness of no greater than about 60% of the thickness of the coating outer portion, typically less than about 1 mil.

Abstract: A method is provided for treating cooperating, juxtaposed substantially uncoated alloy substrate surfaces in preparation for brazing, for example an inner wall of the radially outer open end of a turbine engine blading member with the rim of an end plate or tip cap. The method includes treating at least one of the cooperating surfaces with a reducing gas comprising halogen gas for a time and at a temperature, for example 1-6 hours at 1650-1950° F., sufficient to remove any surface debris, for example oxides, and to deplete the alloy substrate surface of the total of elements selected from Al and Ti to a level of less than about 1 weight %. Depletion is to a depth in the surface which avoids intergranular attack of the substrate alloy surface. For example, the depth is no greater than about 0.0015″. Then the cooperating surfaces are brazed together.
