Abstract: A specially designed rotary indexing system and associated operational methods are incorporated in a downhole control device, representatively a sliding sleeve valve, having an outer tubular member in which an annular plug seat is coaxially disposed. The plug seat is resiliently expandable between a first diameter and a larger second diameter and is illustratively of a circumferentially segmented construction. The rotary indexing system is operative to detect the number of plug members that pass through and diametrically expand the plug seat, and responsively preclude passage of further plug members therethrough when such number reaches a predetermined magnitude. Such predetermined magnitude is correlated to the total rotation of an indexing system counter ring portion rotationally driven by axial camming forces transmitted to the rotary indexing system by successive plug member passage-generated diametrical expansions of the plug seat.

Abstract: The invention refers to a soil cultivation implement with two tool rows of hollow discs of a first hollow discs row and of a second hollow discs row. One hollow disc in the first hollow discs row is positioned slightly offset to the rear. In the second hollow discs row there is a hollow disc in a position offset to the front. In order to prevent lateral pull with a soil cultivation implement of this type the hollow discs rows were positioned relatively symmetrically and were offset where the hollow discs point towards each other with their convex sides or with their concave sides. This offset has the effect of optimising the soil flow and prevents components colliding with each other. This ensures even cultivation over the whole working width of the implement, including in the area of greater working depths with hollow discs that have a larger diameter.
