Abstract
Abstract Preferably for irrigation purposes wherein a sloping conveyance includes multiple and like sized orifices aligned therealong in near level relationship to thereby provide diverted water balanced access to the orifices. A uniflow system incorporating sloping supply, downstream valved-riser and orifice line segmentation in relative position whereby selective valve actuation causes a diversion to well-up to and out the orifices simultaneously and thereby cause the automatic distribution of duplicated flow to the land. Actuator assembly mounting automates the diversion. Actuator mounting in communication with a remote controller further automates diversions through systems programming.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
To automate the diversion of water, a uniflow system comprising; the slope of a conveyance means cooperating with multiple and like sized orifice means set nearly level therealong to thereby allow diverted water access below said orifices; a sloping supply pipe means having downstream valved-riser means connection therebetween with manual control means disposed for selective actuation causing quiet water to well-up to and out orifices simultaneously discharging duplicated flow in automatic distribution.
Claim 2
Dependent Claim
72 words
To automate the diversion of water, a uniflow system comprising; the slope of a conveyance means cooperating with multiple and like sized orifice means set nearly level therealong to thereby allow diverted water access below said orifices; a sloping supply pipe means having downstream valved-riser means connection therebetween with manual control means disposed for selective actuation causing quiet water to well-up to and out orifices simultaneously discharging duplicated flow in automatic distribution.
Claim 3
Dependent Claim
15 words
The combination of claim 1 being further characterized by drop means producing orifice line segmentation.
Claim 4
Dependent Claim
25 words
The combination of claim 2 being further characterized by conveyance support means disposed in selective vertical and axial adjustment maintaining orifice line to water line.
Claim 5
Dependent Claim
24 words
The combination of claim 1 with said manual control being a mounted, powered actuator mechanism means disposed for local use causing a diversion automatically.
Claim 6
Dependent Claim
23 words
The combination of claim 4 with said powered mechanism being further characterized as having communication with programing means causing diversions by remote control.
Claim 7
Dependent Claim
35 words
The combination of claim 1 with said valve being a sleeve insert means in sliding engagement with said riser for selective position capability of diversion and shutoff with said riser disposed for water level monitoring.
Claim 8
Dependent Claim
56 words
The combination of claim 2 with said conveyance orifices being multiple and like sized tube orifice means disposed nearly level with opposite extremity gradient attachment to the supply pipe whereby water colume and slope pressure gradient offset means produces balanced water at the orifices with increasing pressure by diversion simultaneously founting duplicated flow in automatic distribution.
Claim 9
Dependent Claim
29 words
The combination of claim 1 with said valved-riser including a shutoff means mounted in the outlet thereof disposed closed while at rest and to open automatically with diversion actuation.
Claim 10
Dependent Claim
31 words
The combination of claim 7 with said near level tube orifices being orifices set on-grade with supply attachment being further characterized by perforate restriction gradient means disposed to produce pressure offset.
