  • Patent number: 8905493
    Abstract: A composite track link is provided that has a body and a replaceable rail brazed or soldered together to provide a metallurgical bond between the track link body and the rail such that the rail may be removed and replaced by heating the track link or the brazing or soldering filler metal when the rail becomes worn. This process enables the rail to be separated from the body of the track link so a new rail can be brazed or soldered to the body of the track link. As a result, track links or bodies of track links may outlast the rails by multiple use cycles. Further, the body and rail may be formed of different materials.

  • Patent number: 8418638
    Abstract: A combination floating pontoon boat and air-cushion supported hovercraft having a frame and a plurality of pontoons pivotally and retractably mounted to the frame for pontoon boat mode, and a second position extending laterally outward from the frame in hovercraft mode. A skirt is attached to and extends from the frame, the skirt on a first position being retracted against the bottom of the frame. In a second position, the skirt extends downward from the frame and forms an air-receiving pocket beneath the frame for hovercraft operation. A first power system moves the frame through water when the pontoons are in their first position. A second power system drives air into the air-receiving pocket when the skirt is in the second or hovercraft position, and a third power system propels the frame in a longitudinal direction when air is driven into the air-receiving pocket.

  • Patent number: 8113126
    Abstract: A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behavior. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both.
