Patent number: 8905493Abstract: 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.Type: GrantFiled: May 11, 2011Date of Patent: December 9, 2014Assignee: Caterpillar Inc.Inventor: Tianjun Liu

Patent number: 8418638Abstract: 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.Type: GrantFiled: December 29, 2011Date of Patent: April 16, 2013Inventor: Richard Schramer
