Abstract: A method and apparatus for locating, isolating and treating a section of a formation located downhole in a well bore by analyzing the formation for location of the section to be treated and isolating the section to be treated, and subjecting the isolated section with treating fluid with a single-type or straddle-type expandable packer assembly. The treating fluid is fed downhole to the packer assembly through a flexible conduit which is paid-off from a reel located above ground from a mobile unit. The radially expandable packer elements of the straddle packer assembly are independently expanded and contracted with the application of positive expanding and contracting forces applied thereto through remotely located controls above ground. The packer assembly may also include a formation sensing unit for sensing downhole fluid-bearing strata while the packer assembly is being lowered.

Abstract: A disk harrow embodies a fore-and-aft extending center pole which hitches at one end to a tractor and has paired tool gang assembly units which extend laterally from opposite sides thereof. These units include tool gang carrying inner beams which are supported on transport wheels and are connected to said pole for horizontal adjustment about pivots spaced along the longitudinal axis of the pole, one behind the other. Adjustable length truss bars connected between the pole and the inner beams releasably lock said tool gang assembly units in a transport position generally perpendicular to the pole. The tool gang assembly units also include a tool gang carrying outer beam which is hinged to the inner beam to fold vertically thereover onto the pole when the units are perpendicular thereto. The spacing of the pivots provides sufficient clearance that the folded outer beams lie flat with their tools in close side-by-side relation on the pole for transport.

Abstract: A power tool, such as a surgical drill, has a tool element retained in a collet coupled to the output spindle of the tool.

Preferably, the tool is of the cordless type and has a reversible electric motor controlled by a pair of triggers mounted on the pistol-grip handle for the tool. The triggers are conveniently disposed adjacent to each other and are easily distinguishable from one another, thereby providing for a convenient one-hand operation of the tool.
