Abstract: An apparatus connectable toward a downstream end of an agricultural combine for uniformly distributing residue material over a broad area. The apparatus is rotatable within a housing and about an axis extending generally parallel to a longuitudinal axis of the combine for distributing residue material from opposite sides of the combine. In those combines that use a cleaning system including a blower for directing a stream of air rearwardly toward a discharge end of the combine, the apparatus of the present invention accepts the stream of cleaning air from the blower and redirects or turns the air along with the residue material entrained therewith outwardly from opposite sides of the combine to broadly distribute the residue under the influence of an air flow thereby projecting the residue material over a broad area with uniformity.

Abstract: Semiconductor devices, with especial reference to transistors with reduced turn-off times. This improvement includes a low-barrier height metal contact to one of the lightly-doped regions of the device as a replacement for the conventional heavily-doped region or high-low junction structure usually employed for the purpose of providing ohmic contact.
