Abstract: A sprinkler system for lawns and landscaping is custom-fitted to each particular lot or area to be irrigated. Each in-ground, pop-up, rotating sprinkler head has a pattern defining plate fitted therein having a central opening made therein, as by laser cutting, solid particle deposition, or the like, the opening being congruent with the area to be watered, as adjusted for any sloped portions of the area. A pattern sampling aperture aligned with spray nozzles of the sprinkler rotates about the opening in the defining plate, feeding an amount of water to each radial line of the area about the sprinkler sufficient to reach from the sprinkler position out to the periphery. A speed control comprising a spring-biased cam and an opposing turbine wheel in the water flow slows spray head rotation at arc portions of longer water throw and speeds rotation where the throw is shorter, thus to obtain substantially uniform water coverage over all parts of the area served by each sprinkler head.

Abstract: A computer system for monitoring and enhancing the collateral security underlying a set of loans is provided, including a system for calculating the unsecured value of the set at any time and for initiating additional collateral enhancement instruments when the unsecured value exceeds a certain limit. The system may include a variety of modules in communication with a relational database for storing data about the loans and system elements. The computer system may also be configured to allocate, manage, and execute the waterfall or cascade of funds between and among the various participants in a financial plan. The invention also includes a structured finance plan and related methods for enhancing the collateral security of a loan obtained for a life insurance or annuity product, and a system and method for managing a portfolio of such loans in order to obtain favorable financing and to facilitate securitization.

Abstract: A water sprinkler for irrigating lawn and garden areas has two axes of movement, one transverse to the other. A barrel moves or oscillates on one horizontal axis to direct water spray from nozzles carried on the barrel across the length of the area, and the nozzle outlets also simultaneously move or oscillate on axes transverse to the barrel axis to spray water across the width of the area. As the nozzle outlets move or oscillate in the two transverse directions, the ground area is irrigated uniformly over time by application of water in a criss-cross pattern. The area sprayed can be surprisingly large compared with single-axis oscillators, or the area may be limited to a single row or a narrow rectangular area, by adjustment of the barrel and outlet movement and/or the water pressure.

Abstract: A water sprinkler of a new type has a spray arm which oscillates about a horizontal axis transverse or perpendicular to the length of the spray arm, in a see-saw fashion, to distribute water to a length of the lawn or garden area. Spray nozzles spaced apart on a distortable, peripheral wall along the length of the spray arm in a linear array are adjustable, by twisting the peripheral wall of the arm, to a circumferentially-arrayed, helical or spiral pattern, to distribute water to cover a selected width of the lawn or garden area. Both the angle of the oscillation and the twist of the wall may be selectively varied or adjusted to select respectively the length and the width of the area to be sprinkled. The twist is adjustably-fixed along and about the flow passage, as by an internal twist-setting arm. Also, the spray arm may oscillate about its center or one end thereof, depending on the oscillation mechanism used.

Abstract: A vertical-axis water sprinkler with a reversibly rotating spray head has an internal control shell rotating with the spray head in a fixed housing. Adjustably fixed in the housing are a plurality of pattern defining plates. A pattern sampling disk with a specially contoured aperture therein is carried on a control shell within the housing and communicates from a water inlet in the housing to the spray head. The aperture sweeps across the face and edge of each of the pattern defining plates as the control shell rotates in the housing. The positions of the pattern defining plates control or limit the volume of water flow to the spray head, thereby generating a ground coverage pattern conforming to the relative positions of the plates.The speed of rotation of the spray head is made constant despite changes in the output flow rate by design selection of a friction bearing and of the surface areas of the control shell exposed to pressure forces in upward and downward directions.

Abstract: A water sprinkler develops any of several predetermined patterns of water coverage of regular or irregular shape and of varying sizes. The sprinkler includes first a plurality of pattern-defining apertures which are contoured to pass varying but predetermined amounts of water from a fixed sampling aperture as a sprinkler nozzle rotates in either or both angular directions about a vertical axis.Pattern size is incrementally adjustable in one embodiment by a member having tapered apertures of varying sizes interposed between the fixed sampling aperture and the pattern-defining apertures. Pattern size and shape are finely adjusted by a parallel flow line including a valve for providing small additional or slightly reduced flow volumes. Rounded patterns are effected entirely through the parallel flow line.

Abstract: A water sprinkler is described for developing predetermined but variable patterns of water coverage. The sprinkler includes a plurality of pattern-defining apertures which are contoured in accordance with desired patterns of water coverage to pass varying but predetermined amounts of water as a sprinkler nozzle rotates. A sampling aperture progressively samples the outputs of selected pattern-defining apertures in synchronism with the rotation of the sprinkler nozzle so as to conform the water output of the nozzle to that of the desired pattern of water coverage.
