Abstract: A cutting tool having a monolithic construction includes an injection molded shank, and an extruded fluted portion extending forwardly from the shank, the shank and the fluted portion having a monolithic construction. The process for making the cutting tool includes forming a cutting tool green body by injection molding a shank of the green body and extruding a fluted portion of the green body such that the shank and the fluted portion have a monolithic construction; and then sintering the cutting tool green body.

Abstract: A rotary sprinkler comprising a base, a stem mounted on the base for rotation relative thereto, the stem having an inlet for receiving a pressurized water supply, a water discharge nozzle mounted on the stem and being rotatable together therewith relative to the base, water driven drive apparatus for rotating the stem relative to the base, selectably positionable deflector apparatus for engaging a stream of water emitted by the nozzle for determining the maximum radius of the stream, and cam apparatus for operating the deflector apparatus and including manually settable cam apparatus for selecting an overall size and pattern of sprinkler stream coverage, and second cam apparatus for determining the desired sprinkling pattern as a function of the azimuthal orientation of the nozzle.

Abstract: A sprinkler including a body defining a nozzle arranged to provide a stream of pressurized liquid, spring loaded stream deflector and hammer apparatus for intermittently engaging the stream and providing in response to the engagement of a force causing intermittent rotation of the body about a rotation axis, apparatus for selectably limiting the amplitude of motion of the stream deflector and hammer apparatus and thus determining the direction of rotation of the body and the overall range of the spray produced and having first and second orientations corresponding to rotation in forward and return directions, selectably positionable protrusion apparatus for defining the azimuthal limits of a desired irrigation zone; and finger apparatus associated with the selectably limiting apparatus constructed such that positioning of the finger means in a first position for disengagement with the protrusion apparatus results in positioning of the selectably limiting apparatus in a selected orientation.
