Abstract: A grain processing assembly for a combine that comprises a feeder assembly, a threshing assembly having a rotor disposed within a housing, a hood. The feeder assembly comprises a lower conveyor and an upper conveyor. The position of the lower conveyor and the upper conveyor is such that upper conveyor assists the lower conveyor in directing crop material being transported on the lower conveyor towards a discharge end of the lower conveyor. The hood engages a belt of the second upper conveyor.

Abstract: A harvesting assembly for harvesting a crop including a cutting knife configured to provide cut crop and a draper platform including a first side draper and a second side draper. A crop auger assembly includes a first auger disposed at the first side draper and a second auger disposed at the second side draper, wherein the first auger and the second auger each include a cylinder having a surface, a flight extending from the surface, and a plurality of fingers extending from the surface and beyond an exposed edge of the flight, wherein the crop auger rotates about an auger axis. A feed drum is disposed at a center draper wherein the feed drum includes a plurality of fingers.

Abstract: A process for the preparation of compounds of the formula: ##STR1## wherein Pg and R are protecting groups and B is a nucleobase. The process uses protected nucleobases to form 2,2'-anhydro nucleosides having the formula ##STR2## which are hydrolyzed to 2'-hydroxy intermediates which are then oxidized to the desired 2'-keto compounds. The compounds and intermediates are useful as antiviral and antitumor agents and as intermediates to 2,2'-anhydro-1-(.beta.-D-arabinofuranosyl)cytosine (anhydro-ara-C) and 1-.beta.-D-arabinofuranosylcytosine (Ara-C).

Abstract: A lawn mower includes an elongated forwardly open housing having an endless belt entrained therein about a pair of pulleys mounted at opposite ends of the housing. A plurality of C-shaped, channel-like cutting elements are mounted transversely on the outer surface of the belt to cut the lawn as the housing is moved across the lawn on a plurality of rollers. The housing is divided into a plurality of sections which are pivotally interconnected so that the housing sections may pivot relative to each other due to uneven ground. Guide members are provided within the housing to maintain the opposed reaches of the belt parallel to each other during such pivoting of the sections. The cutting elements may also be a plurality of wires embedded in the belt and extending outward from one side of the belt in the plane of the belt.

Abstract: A lawn mower includes an elongated downwardly open housing having an endless belt entrained therein about a pair of pulleys mounted at opposite ends of the housing. A plurality of C-shaped, channel-like blades are mounted transversely on the outer surface of the belt to cut the lawn as the housing is moved across the lawn on a plurality of rollers. The housing is divided into a plurality of sections which are pivotally interconnected so that the housing sections may pivot relative to each other due to uneven ground. Guide brackets are provided within the housing to maintain the opposed reaches of the belt parallel to each other during such pivoting of the sections.

Abstract: The bearing assembly includes a synthetic resinous collar which circumscribes the tube and oscillates therewith against the inside of a metal bushing wedged within a metal housing that is bolted to the adjacent tine tube carrier arm of the reel. The bushing is constructed from a pair of generally semicircular half-sections that are abutted together to make a complete annulus when held within the housing, thereby permitting removal of the bushing from the tube by simply separating the two half-sections from one another after the housing has been slipped axially off the end of the bushing. A slit in one side of the collar permits opposed wall portions thereof to be spread apart so that the collar may likewise be removed from the tube in a transverse direction rather than requiring axial movement along the tube which would be obstructed by crop-engaging tines of the reel.

Abstract: A pick-up header for a combine is designed to improve the control of the material from a windrow as it is picked up from the ground and transported to the feeder housing of the combine. Immediately rearwardly of the pick-up fingers is provided an air transportation device including a plurality of openings through which air is forced to carry the material rearwardly toward the feeder housing while allowing the escape of stones. Rearwardly of the air transportation device is a sheet which inclines downwardly toward the curved feeding surface of the feeder housing with the pick-up, air transportation device and guide sheet all pivotally mounted relative to the feeder housing. A feed roller includes a plurality of fingers which rotate with the roller about an eccentric axis so that the fingers project outwardly at the front of the roller to a length extending just to the rear of the pick-up fingers and then retract at the rear of the roller.

Abstract: In a combine harvester machine, the front conveyor is disposed such that the imaginary extending surface of its placing and conveying surface passes through or adjacent to the peripheral lower end of an auger equipped drum located backward of the conveyor.

Abstract: A harvesting attachment for use in combination with a combine is particularly adapted for harvesting row-crops, such as beans and the like, and is adapted for mounting a plurality of same in spaced apart relation across the forward portion of a combine trough to accomodate the row spacing. The attachment is arranged for driving from the combine and includes a sickle bar mounted on a leading side of a lower portion of a housing and an endless conveyor extending from adjacent the sickel bar to adjacent a trailing side of the housing for moving vegetation into a forward portion of the combine. The row-crop harvesting attachment includes a reel mounted on the housing and positioned above and forwardly of the sickle bar and including a plurality of circumferentially spaced pick-up tines engageable with vegetation for moving same toward the sickle bar.

Abstract: Crop gathering table for a grain combine has belts positioned to convey crop rearwards between a cutterbar and an auger. Each belt is caused to run straight by adjustable guide rollers located between the upper and lower runs of the belt and engaging the edge portions of the inner surface of the belt in its lower run and deflecting said edge portions downwards. The guide rollers are angularly adjustable by a lever mechanism actuable from the front of the table while the belts are being driven.

Abstract: A harvesting and threshing machine having a crop collecting platform carrying a threshing cylinder extending across its full crop collecting width. Crop threshed by the cylinder passes to a straw conveyor mounted behind the cylinder which collects the threshed crop and conveys it laterally. The straw conveyor may itself effect grain separation or may pass the crop to grain separation apparatus.
