  • Patent number: 11864480
    Abstract: A tillage implement has a frame connectable to a towing vehicle and at least two transverse rows of secondary tillage tools mounted on the frame, the at least two transverse rows comprising a row of main rollers mounted on the frame rearward of all other rows of the at least two transverse rows. The implement also has a transverse row of auxiliary rollers mounted rearward of the row of main rollers, the transverse row of auxiliary rollers independently pivotable vertically about a transverse pivot axis. The implement has at least one ground-engaging wheel. Independent pivoting of the row of auxiliary rollers allows an operator to increase tillage/field finish on the go or as needed.

  • Publication number: 20220408625
    Abstract: A tillage implement for variable tillage has a linkage mechanism disposed longitudinally between two gangs of annular harrow tools, the gangs each having a toolbar that is rotationally mounted on a frame of the implement. The linkage mechanism has a plurality of pivotally connected linkage arms, the toolbars each pivotally connected to at least one of the linkage arms. Operation of the linkage mechanism simultaneously rotates one toolbar about a first vertical rotation axis and the other toolbar about a second vertical rotation axis in an opposite rotational direction as the first toolbar. The implement has at least one wheel mounted on the frame longitudinally forward of both of the gangs or longitudinally rearward of both of the gangs. The tillage implement provides variable tillage while having a shorter frame to facilitate folding wing sections of the frame in a more compact manner for transportation while remaining assembled.

  • Publication number: 20220091504
    Abstract: Provided herein is a method of forming a three-dimensional object in which the polymerizable liquid includes a mixture of (i) a light polymerizable first component, and (ii) a heat polymerizable second component; the heat polymerizable second component comprising (i) a first blocked reactive constituent that is blocked with a volatile blocking group, and optionally (ii) a curative. Upon heating a formed three-dimensional intermediate sufficiently, the volatile blocking group is cleaved and vaporizes out of the three-dimensional intermediate, to form the three-dimensional object. Also provided is a three-dimensional object produced by the method. Further provided is a polymerizable liquid composition useful for carrying out the method, and prepolymers and monomers useful for the polymerizable liquid composition.
