Abstract: A liquid presence detector and method of using the same for a gas fluid conduit is provided by a capacitor that is placed inside the conduit and that is formed of two interwoven wire grids with one of the grids being insulated and the other grid being uninsulated. In one embodiment, the capacitor is generally planar and is oriented generally transverse a longitudinal axis of the conduit with a peripheral portion lying in a generally axial orientation along an inner surface of the conduit. A circuit is provided that measures capacitance between the two wire grids. The conduit is electrically grounded. Liquid particles entrained in the gas fluid or traveling along the conduit wall contact the capacitor and changes the capacitance thereof. In another embodiment, the capacitor is formed as a generally open cylinder positioned coaxially within the conduit.

Abstract: A track roller bearing having a floating sleeve between the inner race and outer race. The floating sleeve has a self-lubricating bearing material on its outer surface. The coefficient of friction of the self-lubricating bearing material increases as the material is worn. When the self-lubricating bearing material coefficient of friction exceeds the coefficient of friction of the floating sleeve inner surface, the floating sleeve will rotate with the outer race until a new unworn surface of self-lubricating bearing material is presented to the load area of the outer race. This precessing of the floating sleeve will continue until the entire surface area of the self-lubricating bearing material is worn, thus extending the track roller bearing life.
