Abstract: An articulating assembly of or for an adjustable hinge assembly, the articulating assembly comprising or including a height control arm supporting a mounting element at its distal end and pivotable about its proximal end for height adjustment, a convex member or members (“member(s)”) at or adjacent the distal region of the height control arm defining a distinct or merged pair of convex surfaces, the convex member(s) having a passageway therethrough, a pair of concave members engaged with the convex surfaces of the convex member(s) in a cupping manner, the concave members each having a passageway therethrough, and a pin located through the aligned passageways of the convex member(s) and concave members, the pin also being engaged with the mounting element to couple the mounting element to the height control arm, wherein the pin is dimensioned such that there is a clearance with respect to the passageway of the convex member(s) to allow at least limited articulating movement of the mounting element relative to

Abstract: A coupler assembly to interpose between the arm of the vehicle and a parallel pinned implement having two docks, one on each of the two members able to be caused to slide relative to each other, each dock engagable outwardly to its pin with at least one pin being captive in its dock by a pivoted retention member.

Abstract: A seed drill or seeder of a kind to deposit serial streams of seed each into a disc made trough, trench or the like, characterised by each disc having its bearing mounted to the disc from the inside (i.e. the concave side) and a chute providing member or assembly down which the stream of seeds is to passes, is attached to the bearing from the outside (i.e. the convex side) of the disc.

Abstract: A back hoe bucket assembly of a kind having a bucket defining cavity bounded by spaced end plates, a cutting edge plate, one or more other plates spanning between the end plates, and a hitch assembly on the bucket for attachment to a complementary boom attachment. An angle plate extends above the bucket to span to each of the end plates, to define, together with the or a spanning plate(s), a hollow rigidifying form, and the hitch assembly is fixably attached directly in part, or indirectly in part, to said angle plate.

Abstract: A narrow door opener which has a capability of being mounted in a small space between the end of a door roll of, for example, a curtain door and any impediment spaced therefrom. The door opener has on its flank a waisted region to accommodate a mounting bracket below the axle axis of the door roll to be opened thereby. The flank to flank distance (not counting door roll engagement features) is less than 200 mm and preferably less than 100 mm.
