Abstract: A method for making drip irrigation lines comprises feeding an elongated sheet of flexible polyethylene film to an injection molding machine for injection molding a series of drippers across a face of the film. A moldable thermoplastic material is injected into multiple die cavities, forming separate drippers each simultaneously heat-bonded to the film. Each dripper has a molded labyrinthine flow-restricting passage extending along it. The mold is opened, the film is advanced, and further series of drippers are injection molded across the face of the film. The previously molded set of drippers are closed off by heat sealing a separate strip of flexible film to a face of each molded dripper to form sealed internal pressure-reducing labyrinthine passages in the drippers. An inlet opens into one end of the sealed internal passage and an outlet opens from the opposite end through the film. The outlet is formed and reinforced during the molding process. A second layer of film is overlayed on the sealed drippers and on the film onto which the drippers are heat-bonded. The second film is bonded to the other film along parallel seams between the drippers, and the film is then cut along the seams to form multiple continuous drip irrigation supply tubes with the molded drippers being spaced apart along the inside of each supply tube.

Abstract: A weed control root barrier includes a polymeric sheet material having spaced apart nodules or disks comprising a polymer containing a herbicide. The sheet is porous to permit free passage of water. It may be a non-woven fabric of non-biodegradable polyolefin material. Diffusion of the herbicide directly into the soil is controlled by a barrier material coated on selected portions of the nodules or disks. In one embodiment, essentially all the herbicide in the nodules or disks is directed into the soil via long term migration through and away from the sheet. The barrier layer is coated on portions of the nodules or disks facing the back surface of the carrier to block release of the herbicide to areas of the soil where it is not needed. Exposed surface portions of the nodules can be coated with the barrier material, leaving uncoated sides of the nodules from which herbicide may be released into the soil along a narrow zone of protection generally parallel to the front face of the carrier.

Abstract: A drip irrigation emitter includes a housing containing an inlet opening for receiving water from a supply tube and an outlet opening for emitting water at a pressureless drip rate. A labyrinth inside the emitter receives water from the supply tube through the inlet opening, reducing its pressure and emitting the water at a drip rate. A flexible pressure-compensating diaphragm inside the housing flexes elastically under pressure changes of water entering in the opening from the supply tube. A raised structured surface positioned between the inlet opening and the diaphragm prevents the diaphragm from sealing off water entry to the emitter housing through the inlet opening when water pressure in the supply tube is shut off. The raised structured surface is configured to allow air contained in the soil to be drawn backwards through the emitter at a very slow rate, thereby inhibiting emitter blockage caused by soil ingestion.

Abstract: A method for reducing the rate of diffusion of a slow-release material through a host polymer material to increase the useful life of a slow-release product. An inert fine particulate inorganic material such as an intercalation material having a layered structure is incorporated into a mixture of the slow-release material and the host polymer. The intercalation material has its layers intercalated with molecules of the slow-release material which are accommodated within spaces between the layers of the intercalation material. The particulate material slows the diffusion rate of the slow-release material through the host polymer when compared with the diffusion rate of the same slow-release material through the same host polymer not containing the particulate material. In one embodiment, the intercalation material comprises a nano-clay, the host polymer is a polyolefin, and the slow-release material is a bioactive material such as dinitroanaline. The slow-release product can comprise a drip irrigation emitter device or tube or tape or device used adjacent to an emitter to protect against root intrusion. The intercalation material can comprise a layered nano-clay produced by contacting the clay with a surface modifier to achieve sorption and complexing of the surface modifier between adjacent spaced layers of the clay material, sufficient to expand the spacing between adjacent platelets. This is followed by exfoliating the surface-treated material to separate the platelets, followed by mixing the exfoliated platelets with the polymeric material to form a polymeric matrix from which drip irrigation products can be made.

Abstract: A process for minute dosing of effluent in a gravity media filter includes filtering incoming sewage in a pre-filter to produce a liquid effluent filtered to less than 100 microns, and pumping the effluent from the pre-filter to a pulse-feeding device preferably comprising a pressure vessel having a controlled pulsing unit. Effluent in the vessel is intermittently discharged in short pressure pulses volume controlled at preselected time intervals. The effluent from the pulse feeding device is forward pulse-fed to an array of drip irrigation emitters spread out over a surface area of a gravity filter containing a filter media such as a sand and gravel filter. Small doses of effluent are fed to the surface area of the gravity media filter by the emitters at a rate substantially less than a standard drip irrigation rate, owing to the intermittent pressure pulses. One preferred drip rate is greatly less than 2 liters per hour. The pre-filtering combined with the slow drip rate enhances continuous treatment of pathogens by available oxygen which avoids biological matter forming in the filter media while also maintaining a reasonable load rate.
