| 20080290190 | SPEED LIMITING TURBINE FOR ROTARY DRIVEN SPRINKLER - A speed limiting mechanisms for turbine-driven fluid distribution apparatus usable with compressible fluid such as compressed air and incompressible fluid such as water. In one form, a flow restrictor is located in the turbine discharge flow path, with the turbine discharge port area selected in relation to the turbine inlet port area according to the desired turbine speed with compressed air. In another form, the incoming fluid flows downstream along the surface of the turbine stator, and is then diverted to enter the rotor chamber in the proper direction. A bleed area on the stator which permits a portion of a compressible fluid which has expanded as it flows along the stator surface to flow to bypass the turbine rotor. | 11-27-2008 |

| 20090177330 | WIRELESS MOISTURE PROBE, RECEIVING CONTROLLER AND IRRIGATION CONTROL SYSTEM - A control system for controlling at least one irrigation station in an irrigation system in accordance with an embodiment of the present application includes a moisture probe operable to gather moisture information regarding moisture present in soil at the irrigation station and to periodically transmit the moisture information wirelessly and a controller operable to receive the moisture information and operable to provide control signals to control the irrigation station based on the moisture information to maintain a desired moisture level at the water station. | 07-09-2009 |
| 20090257230 | CASSEGRAIN OPTICAL CONFIGURATION TO EXPAND HIGH INTENSITY LED FLASHLIGHT TO LARGER DIAMETER LOWER INTENSITY BEAM - A flashlight in accordance with an embodiment of the present application includes an LED light source, a lens positioned opposite the LED light source, a convex mirror positioned substantially in a center of the inner surface of the lens, wherein light from the LED light source is reflected off the convex mirror back toward the LED light source and a concave mirror positioned opposite the convex mirror to reflect the light from the convex mirror as a wide diameter beam of light out of the flashlight through the lens. The convex mirror maybe replaced by a substantially flat, mirrored section of the lens if desired. | 10-15-2009 |
| 20090292401 | EXPANDABLE IRRIGATION CONTROLLER - An expandable irrigation controller for controlling a plurality of watering stations in an irrigation system includes a removable front panel and an inner housing, connected to the front panel. The removable front panel includes a plurality of manual controls operable to input instructions for a watering program, a memory operable to store the input instructions and a controller operable to execute the watering program. The inner housing includes a circuit board including control connectors which are connected electrically to the controller and a station module operable to provide an ON/OFF signal to at least one watering station of the irrigation system. The station module is electrically connected to the circuit board via the control connectors and the ON/OFF signal is provided based on instructions from the controller in accordance with the watering program. The control connectors are positioned in a substantially continuous line extending across the inner housing such that the station module is connectable to the control connectors at substantially any desired location. Multiple modules of different sizes may be mounted in the inner housing as desired. Control information may be provided via a radio frequency supply and received by a radio frequency module to be provided to the station modules and to external station modules in an external housing. | 11-26-2009 |
| 20100170963 | SPRINKLER TO TOP RISER AND HOUSING SEAL CARTRIDGE FOR GEAR DRIVE SPRINKLER - A riser seal cartridge for an irrigation sprinkler. The cartridge is formed of a rigid self support shell, and a sealing member formed of a resilient material covering the shell in areas which provide the seal. The sealing member includes a first portion which seals the top end of the sprinkler body, a second portion which seals an outer surface of the riser, a third portion which connects the first and second portions, and a fourth portion extending from the third seal portion which provides a seal for the support shell lower end portion. The first seal portion provides a high pressure seal to prevent leakage when the riser is in a fully extended position; and the second seal portion provides a low pressure seal during pressure build-up as the riser is extending. | 07-08-2010 |
| 20100327083 | ROTARY DRIVE SPRINKLER WITH FLOW CONTROL AND SHUT OFF VALVE IN NOZZLE HOUSING - A flow shut off or throttling valve is provided in a sprinkler nozzle housing to enable a nozzle to be changed without having to turn off a flow pressure source. The valve intersects a flow path through the nozzle housing and has an opening such that when the opening is aligned with the flow path, a flow stream can flow unobstructed through the flow path. The valve is movable between a fully open position in which the opening is aligned with the flow path and a closed position which blocks the flow stream from flowing to a nozzle disposed at an outlet passage of the flow path. The valve may be constructed to be either slidable or rotatable between the two positions, and is actuated by a gearing arrangement which is operable at the exterior of the nozzle housing. The external valve actuator may function as a physical barrier to retain the removable nozzle in the nozzle housing when the valve is open and to disengage the nozzle when the valve is closed. | 12-30-2010 |
