Abstract: A method and apparatus for establishing and maintaining consistent spacing between parallel forms for concrete structures. The elongated spacer includes notches at either end for flush engagement with the upper corners of the parallel forms. An angled notch may be provided for engagement with angled toeboards used in curb construction, and a level may be included for use in setting the parallel forms at a consistent level.

Abstract: An anti-sliding bar for furnace wall constructions of the type comprising: an open support structure wall and mat means of fibrous insulating material, including U,S,C or the like shaped sections interleaved to each other; anchoring means between the interleaved U,S,C or the like shaped sections, and tying means passing through the mat means, to hold the anchoring means attaching the mat means to the open support structure wall; the anti-sliding bar comprising: a rod supporting the mats, extending horizontally between the U, S,C or the like shaped sections, having: anti-sliding means, fastening tying means for supporting the bar to the mesh means.

Abstract: A conservation tillage implement including a shredder with a transverse rotor hood structure having one-piece end panels which are welded to each side of the hood and project rearwardly of the hood to receive a toolbar which extends the width of the implement. The center of the toolbar is connected to a pair of parallel upright central panels which are connected to the central rear portion of the hood. A reinforcing member extends from the central rear portion between the central panels around the top of the hood adjacent the hitch structure which connects the implement to a tractor. The end and central panels and reinforced hood structure define a compact, unobtrusive frame which is sturdy enough to pull heavy drawbar loads and resist heavy torque loading. In one embodiment of the invention, the toolbar supports a plurality of transversely adjustable deep tillage tools such as rippers, and disk structure is connected by adjustable bracket structure to the toolbar behind the rippers.
