Patent number: 8302884Abstract: A cross-flow injector is used to introduce fluids into a chemical vapor deposition process chamber separately and simultaneously for efficiently atomizing and vaporizing the fluids. The cross-flow injector consists of a three port cavity having an inlet nozzle, a throat region, and an exit nozzle. The injector cavity is defined by the tapering of the inlet and exit nozzles to the smaller diameter of the throat region. The tapering allows for pressure differentials at the inlet, throat, and exit regions, and assures the inlet pressure being much greater than the exit region. The throat region consists of additional apertures for injecting dopants and precursors within the fluid flow. The pressure differential at the throat region atomizes and vaporizes the injected dopant and precursor fluids. In a second embodiment, the injector cavity consists of two ports, having an inlet nozzle and a throat region.Type: GrantFiled: September 29, 2000Date of Patent: November 6, 2012Assignee: Novellus Systems, Inc.Inventors: Martin M.

These have a solute containing reservoir or reservoirs with different solutes that easily attach or detach for refilling. When adjusted to go to the showerhead or alternately to the bathtub for both showering and bathing, different amounts of solutes may be added to a reservoir to obtain the amounts most desirable. With such a system the water-solute mixture is able to cover the entire body. By selecting mixtures or adding more or less solutes to the reservoir, the skin is treated in such a way that it becomes softer and not itchy.Type: GrantFiled: September 11, 2007Date of Patent: February 16, 2010Inventor: Gladys P.

Publication number: 20090308951Abstract: A washing device [1000] is described which is uniquely adapted for use by elderly, handicapped, or other users which use one hand for support and have only one hand free to operate the device. Since the washing device [1000] is operated with one hand it allows the user one hand or both hands free to scrub, clean and bathe animals and humans. The washing device [1000] includes a supply line [1010] with a cleaning fluid under pressure. The supply line [1010] directs the fluid to a fluid valve [1210] which is controlled by a first clicking mechanism 1231 which toggles the valve between an “open” position directing fluid flow to an additive valve [1240], and a “closed” position which stops fluid flow. Additive valve [1240] is also toggled between two positions by a second clicking mechanism [1232]. In its ‘fluid only’ position, only fluid is allowed to pass out of the additive valve [1240] through a mixing chamber [1400] and out of a changeable head [1700] to the user.Type: ApplicationFiled: August 20, 2009Publication date: December 17, 2009Inventor: Michael P.

Patent number: 7611070Abstract: A plumbing fixture including an aspirating type showerhead operates to add a selected scent to the spray water. The showerhead utilizes a venturi assembly where the water supply passes through a venturi. A negative pressure is created at the high velocity water jet stream point, near the narrow area of the venturi. A number of small openings in the venturi, to a surrounding air chamber, allow air from the chamber, to be drawn into the venturi. The air chamber has inlet openings for the aspiration of room air. At a portion of these inlet openings is a quick connect port to receive a scented cartridge. The scent cartridge is then inserted into the quick connect port of the showerhead. Room air is then drawn through and over the scent cartridge where the high velocity air picks up scent molecules from the scented wick within the cartridge.Type: GrantFiled: February 28, 2006Date of Patent: November 3, 2009Inventor: John J. Paoluccio

Publication number: 20090224072Abstract: A hose end sprayer comprising a sprayer lid and container includes multiple bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the cap of the sprayer lid. The connectors allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end. A siphon tube intersects the conduit within the periphery of the smallest of the bottle connectors. The siphon tube carries liquid chemical from a container connected to the sprayer lid, such as a bottle of concentrated liquid, into the liquid conduit, where the liquid mixes with carrier water entering the liquid conduit at line pressure from an external hose connected to the hose inlet. The liquid carrier water mixture is then expelled from the nozzle.Type: ApplicationFiled: March 7, 2008Publication date: September 10, 2009Applicant: Root-Lowell Manufacturing CompanyInventor: Michael T.

Publication number: 20090134237Abstract: A system and method for combining an additive with a carrier fluid in a spray nozzle. The carrier fluid is fed to one or more nozzles that include an embedded Venturi. The Venturi includes an induction port connected to an additive supply. As the carrier fluid flows through the nozzle, the flow creates a vacuum or suction force that draws in the additive. Of particular advantage, the concentration of the additive combined with the carrier fluid can be maintained constant even if the flow rate of the carrier fluid varies. The system and process are particularly well suited for spraying fields, such as crop fields or orchards, with an agrochemical.Type: ApplicationFiled: November 18, 2008Publication date: May 28, 2009Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventor: Durham K.
