Abstract: A forage harvester having a cutterhead housing, a rotary reel cutterhead, a recutter screen mounted adjacent the cutterhead periphery and a crop blower for generating an air suction in the outlet of the cutterhead housing is provided with a transverse baffle sheet disposed within the housing in spaced relation from the floor to define the upper side of an air duct separated from the operative region of the recutter screen and extending from beneath the cutterhead area to direct the inlet air across the floor of the cutterhead housing to the discharge mechanism.

Abstract: Tobacco in cigarettes rejected in the cigarette manufacturing operation is recovered by subjecting the cigarettes to a series of ripping actions which open the wrappings to expose the tobacco and a series of screening operations which result in effective recovery of 99+% of the tobacco and with almost no presence of wrappings residue material in the recovered tobacco, the wrappings material being separated to a different collection end point than the recovered tobacco.

Abstract: Metal scrap cuttings are prepared for use in making sintered pieces. The cuttings are physically and chemically cleaned, ground in an inert atmosphere, heat treated in a reducing atmosphere, and sorted according to particle size in an inert atmosphere. Movement of the cuttings into the various treatments is performed by vibratory conveyors located in enclosures sealed from the atmosphere.

Abstract: A forage chopping and propelling device including a casing having an inclined bottom and disposed therein a chopper rotor and a booster impeller that operate as an integrated assembly to receive forage from an inlet, chop the forage and eject the chopped forage out a discharge chute. The forage travels along a rectilinear path from the inlet to the discharge chute and undergoes recutting by at least one recutting bar disposed between the chopper rotor and the booster impeller.

Abstract: A forage harvester connectable to a vehicle such as a tractor for being towed by the tractor. The forage harvester includes a transmission having a horizontal rotatable input shaft and a horizontal output shaft separated by an angle of 100.degree. such that the input shaft can be positioned at an angle of approximately 10.degree. relative to the direction of motion of the forage harvester and generally co-axial or positioned at a small horizontal angle relative to the rotatable drive shaft extending from the tractor power take-off shaft to the input shaft. The forage harvester also includes a rotatable cutting cylinder and a blower for blowing out forage into a forage wagon towed by the forage harvester, the rotatable cutting cylinder and the blower being laterally spaced apart.
