摘要: An adjustable toolmaker's square that includes a one piece body having a pair of legs containing flat accurately machined reference surfaces that meet at an angle that is slightly less than 90.degree. to form a corner. One of the legs forms the base of the device and has a laterally extended groove formed therein in which a slide is movably received. The slide has a bearing surface that can be raised and lowered in regard to the base reference surface whereby the square is pivoted about the corner when it is resting upon a surface plate or the like whereby the other reference surface can be accurately positioned against a workpiece or the like.

摘要: The present invention is directed to an irrigation controller, method and software program product for generating valve control signals for energizing a valve. The irrigation controller includes a valve actuation control module selectively coupled each of plurality of control nodes and generating a valve actuation control signal thereon. The valve actuation control signal is a continuous control voltage over a plurality of control signal periods for selectively energizing the selected irrigation valve. Also integrated in the irrigation is a valve chatter module for selectively coupled each of plurality of control nodes and generating a valve chatter control signal thereon. The valve chatter module selectively and, intermittently, energizes the selected irrigation valve. The irrigation controller may further include a remote controller of remotely controlling the irrigation controller.
