The Visual and Near-Infrared Spectrum of Methane and its Application to Uranus, Neptune, Triton and Pluto.

The machine has a rotatable material pickup device movably supported on a portable frame for movement relative to the rear end of the frame to a lowered material pickup position and to an elevated position wherein a formed bale can pass thereunder. A pair of fixed vertically spaced rollers are located forwardly of the pickup device. A third roller is movable longitudinally of the frame in a path above and to opposite sides of the upper one of the rollers and is continuously yieldably urged in a direction toward the front end of the frame. A continuous belt means is initially trained about the pickup device, the bottom fixed roller and the movable roller, with the lower run of the belt means, extended between the pickup device and the bottom fixed roller, lying in a substantially horizontal plane adjacent the ground surface. As the portable frame is advanced along a windrow, the material gathered by the pickup device is engaged by the lower run of the belt means for compaction and rolling on the ground surface. During a bale forming operation the belt lower run is progressively extended about the bale concurrently with the rearward movement of the third roller to train the flexible means about the upper fixed roller. On completion of the bale, the pickup device is elevated and the frame moved away from the ground supported bale.
