Abstract:
An irrigation conduit (10) includes a plurality of emitters (11) spaced apart along its length. A conveyance channel (12) is connected to each emitter (11) and is long enough so that a distal end (14) of the conveyance channel (12) may be positioned at or just above the soil surface with the conduit (10) buried below the soil surface. Each emitter (11) or each conveyance channel (12) includes associated with it a flow control arrangement (30) to control the rate of flow through the conveyance channel (12) when water is applied to the conduit (10) at a desired pressure and flow rate. The flow rate through each conveyance channel (12) exceeds the local hydraulic loading rate of the soil adjacent to the conveyance channel (12). The rate in excess of the local hydraulic loading rate causes localized flooding and allows the water to spread out substantially across the soil surface prior to moving downwardly into the soil.
Abstract:
A temperature sensor probe is provided with a series of flow channels for deflecting a fluid to be sensed as it flows over the surface of the probe. The flow channels reduce the separation of flow from the surface of the probe thereby increasing the convective heat transfer of the probe and improving the time response of the probe. The temperature sensor probe includes a temperature sensing element housed in a probe housing. In channels are formed on the outer surface of the probe housing. In the preferred form of the invention, the housing is cylindrically shaped and the flow channels extend around the entire circumference of the housing in a spiral fashion so as to form a helical shape extending substantially the entire length of the probe housing.
Abstract:
An ornamental planting landscape irrigation distribution and reservoir product and method ecosystem employing a substantially continuous panel on the soil surface on which ornamental landscape plantings is placed or produced, the panel having a primary, lateral water distribution structure which distributes water from a water charging inlet through the lateral area to the panel periphery, where it is restrained, the primary water distribution structure being such that when filled with water or completely submerged in water air is trapped by the gaps and spaces of the material for ornamental landscape plant usage.

Abstract:
A method and apparatus provides a controlled, continuous up-and-down motion of a pop-up sprinkler head device during an irrigation period to approximate a modified sine wave output from the pop-up sprinkler device assuring uniform coverage of an area to be irrigated without excessive watering.
Abstract:
Apparatus for attachment to a plumbing system having a warm water outlet, for rapidly delivering hot water through the plumbing system to the warm water outlet, comprising a diverter valve attachable to a building water pipe upstream of the warm water outlet for purging cold water from the water pipe, a diverter pipe section extending from the diverter valve, a back flow preventer in flow relationship with the diverter pipe section, and a flow control regulator in flow relationship with the diverter pipe section, whereby a small controlled flow of cold water may be diverted from the water pipe to thereby cause rapid delivery of warm water to the warm water outlet when actuated.
Abstract:
The system and apparatus according to the invention includes a panel of material which is made up of a body of open cell, reticulated, porous material (e.g., polyurethane foam) surrounded on the sides and bottom by a barrier of waterproof material. A layer of highly reflective, water permeable material is positioned on top of and covers substantially all of the top surface of the body of porous material. A drain can be positioned at the bottom of the panel to provide a slow, gravity feed to release water from the panel.

Abstract:
A modular planting and irrigation device, system, and method for growing gardens on elevated rooftop surfaces and other surfaces and method of the same. The system has at least one body of porous material with spaces that trap air within the body as water moves therethrough. The water is contained within the body of porous material with a barrier positioned adjacent the side and bottom surfaces of the body. The pore spaces are of sufficient size to allow plant roots to grow therethrough.
