Abstract: A channel for fluid flow comprising a first unit and a second unit connected to each other. The first unit comprises a first u-section having a first open top side, and a first grate extending across the first open top side and removably attached to the first u-section. The second unit comprises a second u-section having a second open top side, and a second grate extending across the second open top side and removably attached to the second u-section. The first grate defines a negative semicircular distal end having a first diameter and a first center point. The second grate defines a positive semicircular proximal end having a second diameter and a second center point. The first center point is coincident with the second center point and the first diameter and the second diameter are sized such that the positive semicircular proximal end fits within the negative semicircular distal end.

Abstract: A locking system comprising a block made of a polymer substance having an upper surface and a lower surface. In a normal condition, the block has the following structure. A bore, having a first axis, extends through the block and passes through the upper surface and the lower surface, the bore being shaped to include a taper, whereby an upper end of the bore has a larger diameter than a lower end of the bore, and the bore has an internal surface that is smooth. And, a slot, having a second axis, extends through the block and passes through the upper surface and the lower surface, the slot having a generally planar configuration with a width and a thickness, the slot being positioned such that the first axis and the second axis are co-axial, whereby the slot and the bore form a single continuous opening extending through the block.

Abstract: A catch basin comprising a circular collar with a first internal diameter, configured to receive a downwardly extending circular drain pipe. A sump for receiving downward water flow from the circular collar is integrally formed with the circular collar, the sump being shaped to include two differently shaped cylindrical portions. The shape of the sump facilitates both the ability to stack multiple units of the sump one upon another for packaging, shipping, and sale. The shape of the sump also facilitates the ability to remove an internal stub attached to the sump, to improve water flow in the remaining structure.

Abstract: A pop-up emitter comprising a base defining a circular bore along a central axis. The base further defines a circular opening at a distal end of the bore. A hub is provided, defining an aperture, positioned in the center of the opening. A circular cap is provided, sized to fit inside the opening, the cap including a spike extending perpendicular to the cap from the center of the cap. The spike resides movably within the aperture such that the cap is movable between a closed condition in which the opening is closed, and an open condition in which the opening is open.

Abstract: A pipe connector for use in conjunction with a catch basin, the pipe connector having an annular flange defining a central bore and a major pipe receptor in the form of a tube having a first diameter and being attached to the flange and a minor pipe receptor in the form of a tube has a second diameter smaller than the first diameter, and is attached to the major pipe receptor by a frangible bridge that is configured to cleanly break upon the application of an impact to the minor pipe receptor, whereby the minor pipe receptor is removable from the major pipe receptor.

Abstract: 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.

Abstract: 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.

Abstract: 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.
