|20140374502||ADJUSTABLE DRIP EMITTER - A flow-regulating drip emitter, comprising a base that includes an inlet connector configured for connection to an upstream line with a water source; and a cover attached to the base, the cover including an outlet connector configured for connection to a downstream line. At least one of the cover or the base defines at least a first labyrinth passageway having a first resistance to water flow and a second labyrinth passageway having a second resistance to water flow different from the first resistance to water flow; and further wherein the base and the cover are structured so that movement of the cover in relation to the base connects the inlet connector to the outlet connector via only the first labyrinth passageway, and wherein further movement of the cover in relation to the base connects the inlet connector to the outlet connector via only the second labyrinth passageway.||12-25-2014|
|20130287493||MARKER FOR PERMEABLE PAVER - A marker for attachment to a permeable paver that includes a structure having a plurality of honeycombed, hexagon-shaped cells with upstanding sidewalls, the sidewall of each cell having an upper surface and a lower surface, an inner surface and an outer surface, and a thickness, the marker comprising a generally planar cap having a substantially hexagonal perimeter that is dimensioned to span across a hexagon-shaped cell of the paver such that the perimeter of the cap substantially matches the outer surface of the sidewalls of the cell.||10-31-2013|
|20120266971||SPRINKLER CANISTER SEAL - An irrigation sprinkler canister seal comprising a flanged screw having a threaded rod and a circular flange extending perpendicular to the rod. The seal further includes a plug piece having a threaded bore adapted to receive the threaded rod, and further including a continuous frusto-conical surface extending around an elongate axis of the plug piece, the frusto-conical surface being configured to form a circumferentially continuous fluid seal against a cylindrical rim of a cylindrical bore.||10-25-2012|
|20120223156||CLAMP AND SPIKE FOR FLEXIBLE CONDUIT - A clamp and spike combination for use in conjunction with a flexible conduit, comprising a spike including an inlet rod with a sharpened tip for penetration into the conduit, an outlet rod connected to the inlet rod, the outlet rod having a barbed tip for attachment to a tube. The bore extends through the rods from the sharpened tip to the barbed tip, whereby the spike provides a channel for the passage of fluid. Further included, a clamp including two legs extending substantially parallel with each other and spaced apart from each other by a distance, an apex portion connecting the two legs to each other so that the clamp is shaped substantially in the form of an inverted “U”; and an opening in the apex portion, the opening being sized to receive the inlet rod of the spike.||09-06-2012|
|20120203382||WEATHER BASED IRRIGATION CONTROLLER - A weather based irrigation controller has a thermometer that provides a temperature signal to the controller and a rain gauge that provides a rainfall signal to the controller, for adjusting irrigation schedules. A default mode is initiated when either sensor fails, and introduces an adjustment to the maximum irrigation duration based on historical stored data.||08-09-2012|
|20110231025||SYSTEM AND METHOD FOR IRRIGATION CONTROL - A method of controlling the duration of irrigation is described, comprising compiling a database that includes information relating to historical evapo-transpiration rates for a plurality of sectors (preferably identified by zip code) located within a geographical area. Period Reduction Factors for each sector are derived. Parameters are entered into the controller including a Maximum Irrigation Duration, a sector identifier; and the current date. The Maximum Irrigation Duration is adjusted by multiplying the Maximum Irrigation Duration by a Period Reduction Factor for the current period associated with the sector that has been identified by the user, to obtain an Actual Irrigation Duration. The irrigation system is caused to irrigate for the Actual Irrigation Duration during the current period.||09-22-2011|
|20110220526||SYSTEM AND METHOD FOR PACKING COILED MATERIAL FOR TRANSPORT AND DISPLAY - A method and assembly for packing a plurality of similar items of coiled material, each item having an annular shape with an internal circumferential surface of first diameter. A sheet of cardboard is folded to form a hollow cylindrical post having a triangular cross section with only three sides and three corners. The post is shaped so that an imaginary circle of second diameter drawn around the triangular cross section passes through each of the three corners, wherein the first diameter is equal to the second diameter The coiled material is sequentially positioned over the hollow post so that the internal circumferential surface of each item is in substantial contact with each of the three corners. At least two ties are positioned and tensioned to bind the items of coiled material to the post.||09-15-2011|
|20110048612||EXPANSION REPAIR COUPLING - An expansion repair coupling for interconnecting two facing ends of a cut pipe comprises a tubular body, a spigot slidably and rotatably received therein and a locking mechanism to selectively lock or unlock the rotation of the tubular body relative to the spigot. An end of the spigot extends outward from the tubular body to receive a coupling that connects to one end of the cut pipe. A radially enlarged section on the spigot has a sealing mechanism that sealably engages an interior surface of the tubular body. The locking mechanism, engaged by collapsing the spigot into the tubular body or disengaged by extending the spigot therefrom, facilitates a push and twist connection at both ends of the pipe to wipe the adhesive disposed therebetween and obtain a better seal. Preferably, the locking mechanism comprises a socket having spigot engaging members that cooperatively engage socket engaging members on the spigot.||03-03-2011|
