  • Patent number: 6241605
    Abstract: The discharge section of an axially arranged rotary combine is provided with a discharge chute having a ramp on the downward swept side. The ramp is provided with upper and lower metering edges for metering the flow of crop material other than grain from the helical flow to a transverse discharge beater. The floor of the discharge chute is provided with three guide vanes that define specific flow paths of the crop material being expelled by the axial crop processing unit and directing this crop material uniformly across the transverse discharge beater. The upward swept side of the discharge chute is provided with a filler plate for engaging crop material that was not engaged by the vanes to direct this crop material to the upward swept side of the discharge beater.

  • Patent number: 6227318
    Abstract: Superhard material enhanced inserts include a body portion adapted for attachment to the earth-boring bit and a top portion for contacting an earthen formation to be drilled. The top portion includes a substrate and a layer of superhard material over a portion of the substrate other than in the outer lateral face. For example, superhard material is provided on the leading edge, the leading face, the crest, the trailing edge, and the trailing face, but not on a portion of the outer lateral face of the top portion. Suitable superhard materials include boron nitride and diamond.

  • Patent number: 6195970
    Abstract: In a tool, the terminal contacts of a battery pack which can be removed from the tool can be connected to the terminal contacts of the drive motor via a bow plug, and for this purpose the terminal contacts of battery pack and motor are arranged parallel to one another in the installed state of the battery pack. The battery pack can only be separated from the tool after the bow plug has been pulled off. Instead of the bridging bow plug, it is possible to attach a charging plug, which connects the terminals of the battery pack to a charging appliance.

  • Patent number: 6158534
    Abstract: A core sampler, particularly for oil prospecting, including a coring bit (2), an outer barrel (3) for rotating the coring bit (2), and an inner barrel (5) for receiving the core sample (7) in its internal space (8) during coring, the inner (5) and outer (3) barrels being substantially coaxial, and further comprising an intermediate barrel (15) coaxially arranged between the inner (5) and outer (3) barrels and defining a first longitudinal coring fluid channel (16) with the outer barrel (3), and a second longitudinal coring fluid channel (17) with the inner barrel (5), as well as said longitudinal channels (16, 17) and valving for at least temporarily selectively causing and/or cutting off coring fluid communication between the rear end (17B) of the second longitudinal channel (17) and/or the rear end (16B) of the first longitudinal channel (16) and/or the rear end (8B) of the internal space (8).

  • Patent number: 6074298
    Abstract: A leveling auger for an extendable height combine grain hopper is mounted onto supports pivoted on brackets so that the auger is effective to level grain in the hopper extension space when in a usable position. The auger will move grain into the regions defined by the hopper extensions. The supports can be pivoted to move the leveling auger to a lowered position. When in its lowered position, the auger is below the level of the hopper after the extension walls are folded down for clearance purposes. A separate grain level sensing switch is used for operating the leveling auger so that the leveling auger is run only when grain has reached a preselected height in the grain hopper.

  • Patent number: 6062011
    Abstract: A conveying device for stem-bearing crops which is provided with two rotatable circular blades and two rotatable housings above for receiving tines, is to be designed in such a way that the tines are fixed to the rotatable housing in such a way that the risk of breaking is substantially reduced, so that the service life of the tines is substantially increased. The tines are permanently inserted in bearing plates. Each bearing plate is mounted freely rotatably on a fixed bearing pin, the longitudinal center axis of the bearing pin being parallel to and spaced apart from the axis of rotation of the cylindrical housing. On the bearing plate on the outside on two bolts are mounted roller bearings which roll over the control face of a control cam which is also mounted on the bearing pin. The control cam is not rotatable relative to the bearing pin, but slidable in the axial direction, and is pressed by a plate spring assembly toward the roller bearings.

  • Patent number: 6052980
    Abstract: A deck for a rotary cutter includes upper and lower deck walls configured together with vertical aprons and wheel support plates at the opposite sides of the deck to form a box structure. Three gear box supports are welded within three pairs of vertically aligned holes respectively provided in the upper and lower deck walls. The upper deck wall is shaped generally convex in fore-and-aft, vertical cross section and is free of ledges formed from framework of stringers so that debris tends to fall off and water tends to run off the deck.
