| 20100227430 | PROCESS FOR DEPOSITING BORON COMPOUNDS BY CVD OR PVD - The present invention relates to a process for depositing films on a substrate by chemical vapour deposition (CVD) or physical vapour deposition (PVD), said process employing at least one boron compound. This process is particularly useful for fabricating photovoltaic solar cells. The invention also relates to the use of boron compounds for conferring optical and/or electrical properties on materials in a CVD or PVD deposition process. This process is also particularly useful for fabricating a photovoltaic solar cell. | 09-09-2010 |
| 20110011129 | METHOD FOR RECYCLING SILANE (SiH4) - The invention relates to a method for recycling silane that comprises the following consecutive steps: a) injecting a mixture of pure silane/pure hydrogen (SiH4/H2) in a reaction chamber for making silicon-containing thin layers; b) extracting from the mixture the excess of silane not used during step a)/hydrogen (SiH4/H2) via a pump using a supply gas; c) discharging from said pump, at a pressure close to the atmospheric pressure, a mixture containing at least silane (SiH4), hydrogen (H2) and an amount different from zero of said supply gas; d) separating the silane (SiH4) from the hydrogen/supply gas mixture resulting from the mixture from step c), the silane thus obtained containing less than 100 ppm of supply gas, preferably less than 10 ppm of supply gas and more preferably less than 1 ppm of supply gas; characterised in that at least 50%, preferably 70%, and more preferably 80% of the silane (SiH4) from step b) is reused after step d) for a new step a). | 01-20-2011 |

| 20100090024 | SPRINKLER WITH VARIABLE ARC AND FLOW RATE - A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler. | 04-15-2010 |

| 20090188988 | SPRAY NOZZLE WITH INVERTED FLUID FLOW AND METHOD - A spray nozzle and method are provided in which fluid flow through the nozzle is inverted and in which a portion of a nozzle body may be rotatable adjusted to distribute water in a desired arc of coverage. Water first flows upwardly through the nozzle body, into an adjustable arcuate chamber defined by a helical interface in the nozzle body, is inverted, and is redirected downwardly through the nozzle body. Water may flow upwardly through a first set of flow passages and downwardly through a second set of flow passages. Water is directed downwardly against a distribution surface having an uneven surface profile for improved water distribution to terrain near to and distant from the nozzle. The water is directed downwardly against the distribution surface in the nozzle body and outwardly to surrounding terrain. The flow passages may be adapted to provide a matched precipitation rate for nozzles with different throw radiuses. | 07-30-2009 |
| 20110147484 | POP-UP IRRIGATION DEVICE FOR USE WITH LOW-PRESSURE IRRIGATION SYSTEMS - A pop-up irrigation device for use in a low pressure irrigation device is described. The device has a housing, a riser partially extensible from the housing and a nozzle body removably attached to an end of the riser in a non-threaded manner, such as using a snap-fit, or in a threaded manner. One, two or more connection tubes or ports may extend laterally from the housing and can each be configured to be connectable to flexible irrigation tubing. Ribs may extend from the housing to facilitate retention when buried. An annular cap can be attached to the open end of the housing and may include an annular, radially-inward extending seal. The closed end of the housing may include a depending stake with a plurality of blades to facilitate mounting of the housing relative to the ground. | 06-23-2011 |
| 20110147488 | NOZZLE BUSH FOR USE WITH IRRIGATION DEVICES - A nozzle bush is provided for use with an irrigation device, such as a pop-up irrigation device. The nozzle bush includes a plurality of different nozzle bodies removably attached about its periphery, and may include an integrated flush port that can be attached to an irrigation device. | 06-23-2011 |
