Abstract: A system that includes a first winch assembly having a first structure on which a fuel hose is configured to be spooled and unspooled, the first structure having a first rotational axis. The system also includes a second winch assembly located rearward of the first winch assembly, the second winch assembly includes a second structure on which a messenger line is configured to be spooled and unspooled, the second structure having a second rotational axis and being rotatable between first and second rotational positions. Upon the second structure being in the first rotational position the second rotational axis is non-orthogonal to the first rotational axis. Upon the second structure being in the second rotational position, the second rotational axis is orthogonal to the first rotational axis. The second structure including an axial through opening through which the fuel line is configured to pass when the second structure is in the second rotational position.

Abstract: There is provided a tool for trueing and dressing a variety of grinding wheels to an open and aggressive surface condition, comprising a wheel having a thin layer of diamond particles in a plane oblique to the rotational axis of the tool. There is also provided a method for trueing and dressing a grinding wheel, by engaging the periphery of a rotating grinding wheel with a rotating trueing and dressing tool having a thin layer of diamond particles in a plane oblique to the rotational axis of said tool, with the diamond layer forming a reciprocating point having an effective cutting crossfeed rate relative to the speed of said rotating tool and the angle of said diamond layer.

Abstract: There is provided a tool for trueing and dressing a variety of grinding wheels, comprising a metal block having a thin vertical layer of diamond particles forming a contacting surface. The tool may have a straight edge profile for trueing and dressing Type 1A1 grinding wheels or be fabricated with a non-linear profile for trueing and dressing grinding wheels with complementary profiles. There is also provided a method for trueing and dressing a grinding wheel, by angularly engaging the periphery of a rotating grinding wheel with a stationary trueing and dressing tool having a thin vertical layer of diamond particles. The diamond layer of the tool forms a single point having an effective cutting crossfeed rate relative to the rotational speed of the wheel, the speed at which the wheel is presented to the trueing and dressing block and the angle of said diamond layer within said block relative to the path of travel of the wheel.

Abstract: A dresser tool comprises two composite compacts positioned to crush and shear the grinding wheel. Preferably one composite compact is arranged such that its working edge contacts the grinding wheel tangentially; and the other compact is placed so that its working edge is normal to the grinding wheel at a rake angle ranging from positive to negative.
