Abstract: A gear driven oscillating sprinkler head has a gear train transmitting rotational drive from a drive motor to the oscillating sprinkler head with a shifting drive mechanism which includes alternately engageable driving devices providing oscillation. An over-center spring maintains the direct driving engagement bias for a driving device on each side of a center position of the shifting drive mechanism. An over center spring carry device places a bias against the shifting drive mechanism to move the shifting drive mechanism over its center position once a driving device has become disengaged from driving the sprinkler head, during a reversing action, so that the over-center spring now biases the shifting drive mechanism in the alternate driving engagement position. Adjustable arc of oscillation includes adjustment to full circle rotation.

Abstract: A sprinkler nozzle has a plurality of flow passages for forming a desired precipitation pattern between the nozzle and its full range. A conventional nozzle flow passage is used for long range coverage with other secondary flow passages used to provide for close-in droplet coverage. Some passages have a staggered flow wherein water flow is directed through large angle turns for close-in fall-out; secondary passages are also directed to impinge one stream at an angle into a second stream; and secondary passages are also directed onto a concave curved arcuate, or cylindrical, surface to splash outwardly and be deflected along the surface and exit at different angles for a distribution of droplet fall-out.

Abstract: An oscillatable nozzle sprinkler has a primary valve for controlling flow through a nozzle in a nozzle housing. An arc set control sets a desired angle of oscillation of the nozzle housing. An integrated system is set forth so that when a desired angle of oscillation is selected, the primary valve is positioned to provide a desired precipitation rate. A secondary valve is provided to achieve a uniform precipitation coverage.

Abstract: A basic controller concept is disclosed for a sequencing distributing valve having a series of multiple outlets and a control timer to direct a like series of timed output signals thereto which allows the sequencing distributing valve to be rapidly pressure cycled to a desired outlet with synchronization between the sequencing distributing valve and control timer being established by a first pressure sensor for sensing cycling pressure and a second pressure sensor for sensing a pressure from a selected outlet of the sequencing valve. Continuing synchronization during cycling is provided by the valve housing pressure sensor which can advance the control timer each time the housing pressure of the sequencing distributing valve indicates that the sequencing distributing valve has cycled.

Abstract: A laser nozzle and optical cavity wall construction is formed of a plurality of stacked blocks bonded together to prevent inter-nozzle leakage and optical cavity sidewall mismatch in the flow area significant thereto. The blocks are formed having end sections which are bonded together with contoured center sections forming the plurality of nozzles and with integral elongated projections extending downstream to form the optical cavity walls. The blocks have hollow ends which absorb thermal expansion in bending rather than in crushing and tension. The laser device flanges holding the ends of the blocks are also provided with a cantilevered spacing block which maintains a seal load while allowing for expansion, preventing undue stresses resulting from temperature changes.
