Abstract: A database rollback processor allows rollback, or rewind, of the data and metadata to a point at which a failover or other metadata change occurred, therefore “rewinding” the metadata to a previous consistent point. The rollback processor identifies transaction entries in a redo log resulting in changes to the metadata. The changes are identified backward to a target recovery time. Transactions affecting the metadata are stored in a stack. The transactions are then backed out of the metadata according to the stack to restore the metadata to the state at the target recovery time. Data changes from the redo log may then be applied to the corresponding metadata as it existed at the target recovery time. Since the target recovery time is not bound by the timing of the snapshots, but rather may be at an arbitrary point chosen as the target recovery time, a failover, replication or recovery operation need not rely on the snapshot time.

Abstract: The grain holding bin of a combine harvester can be rapidly unloaded either on-the-go or at a standstill by an inclined unloading conveyor having its intake end at a low point in the bin adjacent the far side of the bin. The unloading conveyor extends gradually upwardly and outwardly in a straight line from its intake end to a point above and beyond the opposite side of the bin to provide a straight, unrestricted run for grain being unloaded without twists, turns and significant breaks in auger flighting. The outer end of the unloading conveyor can be pivoted back into a rearwardly extending transport position about a simple generally upright pivot hinge.

Abstract: The arcuate processing assembly of a combine harvester may be pivotally adjusted generally radially toward or away from a rotary processing device to adjust the operating clearance between the periphery of the rotary device and the assembly. Simultaneously with such adjustment of the assembly as a whole, in a compound pivoting action one arcuate member of the assembly is also pivoted relative to the other arcuate member to properly reshape the threshing region for the adjusted running clearance.

Abstract: The rotary beater has a number of untwisted, flat, feeding plate segments angularly disposed about its periphery. The plates are arranged in a left-hand group and a right-hand group so oriented that they converge the crop material centrally as they feed and accelerate the crop material rearwardly toward and through the inlet of an axial flow threshing rotor assembly. The feeding segments of each group are arranged in diametrically opposed sets containing at least one segment each, and the sets of one group are offset circumferentially 90° from the sets of the other group. Each segment has a hardened crop-engaging face, and the segments are all detachably bolted to the drum of the beater to facilitate removal and replacement when worn or damaged.

Abstract: The cleaning apparatus of a combine harvester has an oscillating sieve assembly and an oscillating pan assembly beneath the sieve assembly. The sieve assembly comprises a pair of superimposed sieves, both of which are mounted on the same frame for oscillation in unison and always in the same direction. The pan assembly comprises a clean grain pan and a tailings return pan both mounted on a common frame that is separate from the frame of the sieve assembly so that the pans oscillate separately from the sieves. The sieve and pan assemblies are mounted and driven in such a manner that the feed stroke of each assembly is in the same direction as its direction of conveyance, so as to maximize their ability to deliver materials in the intended direction.

Abstract: The combine harvester (10) has a bar (94) with male ends (96) and (98) attached to the elevator housing (20). The male end (96) has an arcuate surface (100) and the male end (98) has an arcuate surface (102). A left female arcuate section (158) and a right female arcuate section (160) are secured to the header frame (64). An arcuate plate (168) of the arcuate section (160) engages the arcuate surface (100) and an arcuate plate 182 of the arcuate section 160 engages the arcuate surface 102. A hook assembly (110) in the lateral center of the elevator inlet (47) and below the floor (24) of the elevator housing engages the round bar (154) and clamps the header (62) to the elevator housing (20). A hydraulic cylinder (196) is connected to the elevator housing (20) and the header (62) and pivots the header relative to the elevator housing about a generally horizontal fore and aft axis adjacent to the hook assembly (110).

Abstract: The stripper header attachment (10) has a stripping rotor (64) and an auger (116). A formed cut-off feed plate (82) feeds heads, grain and other plant residue stripped from stalks to the auger (116). To improve feeding, a smooth roller (102) extends up through a slot (100) in the feed plate (82). A front seal (104) and a rear seal (106) prevent grain loss between the smooth roller and the sides of the slot (104). A three speed gear box (170) drives the stripping rotor (64) and smooth roller (102). A front hood (144) is pivoted about the axis of the stripping rotor by the hood adjustment cylinder (150) to adjust the height of the nose portion (146). Auger housing covers (162) with screens (168) are pivotally attached to the rear hood (158) and enclose the auger housing.
