  • Patent number: 7318554
    Abstract: A method and system are provided for injecting a color component into a plural component coating dispensing system. Base, cure and color components are pumped from respective containers at metered volume. The color component, which is preferably a low-viscosity automotive paint is injected into the either the base or cure stream at a point immediately prior to mixing all components in a dispensing device for dispensing the resulting colored fluid mixture onto a surface to be coated. The mixture may be dispensed by pouring or spraying onto the surface. The method and system are particularly useful for mixing and dispensing colored polyurethane or polyurea coatings, such as for spray-on truck bed liners.

  • Patent number: 7311270
    Abstract: An eductor for mixing liquids and solid particles includes a nozzle, an initial mixing chamber, a first diffuser, an intermediate mixing chamber and a second diffuser. The nozzle includes a semicircular nozzle outlet that is offset from a centrally-located first axis. Motive flow is accelerated through the nozzle through a first and second acceleration segment. Solid particles are added to the motive flow in the initial mixing chamber and directed to the first diffuser. Each diffuser includes an acceleration and a deceleration segment separated by an elliptically-shaped throat. The intermediate mixing chamber is located between the first and second diffusers.

  • Publication number: 20070278327
    Abstract: The fluids mixing nozzle includes a mixing chamber, a first fluid supply port, a second fluid supply port, a nozzle port and a converging-diverging nozzle. The mixing chamber includes a first side and a second side. The first fluid supply port flowably communicates with the mixing chamber. The second fluid supply port flowably communicates with the mixing chamber. The first fluid supply port and the second fluid supply port are disposed on the first side of the mixing chamber. The nozzle port is disposed on the second side of the mixing chamber and allows fluid communication between the mixing chamber and the converging-diverging nozzle. The converging-diverging nozzle includes a nozzle intake section, a convergent mixing flow zone, a throat section, a divergent mixing flow zone and a nozzle exit section.

  • Patent number: 7264179
    Abstract: A nebulization system, which creates a uniform fog of tiny suspended liquid droplets, to lubricate the surfaces of MEMS devices. These droplets fall over the edge of a baffle and are then mixed with an umbrella-like sheet of N2 turbulation gas to generate a uniform cloud of droplets that fill a passivation chamber. The MEMS device is then positioned in this uniform cloud of lubricant droplets for a specified amount of time, thereby uniformly lubricating all the surfaces of the device. The system uses a laser monitoring approach to control the uniformity of the lubricant cloud by providing feedback to the system to control the flow of gases. The system also equalizes the pressure around the sample device seal to prevent gases from entering or exiting the chamber and thereby influencing the environment inside the chamber.

  • Patent number: 7252243
    Abstract: Method and apparatus for uniformly injecting a fluid stream into a gas stream at elevated temperature by means of an injection nozzle comprising a nozzle head and a supply inner tube being concentrically surrounded with an outer casing tube spaced apart from the inner supply tube. It comprises passing the fluid stream through the inner tube and the nozzle head and maintaining temperature of the fluid stream in the inner tube by providing thermal insulation in at least part of an annular space between the inner tube and the outer tube. Further it comprises maintaining a constant flow of the fluid inside the inner tube and nozzle head by plugging the nozzle head at outlet end and spraying the fluid stream through a number of nozzle holes provided in the nozzle head adjacent to the outlet end of the nozzle head.

  • Publication number: 20070176023
    Abstract: A side spray has a hand-held spray unit connected via a manifold to two fluid input supplies. The manifold converts the two separate input supplies into a joint output supply, in which a first fluid feed is partitioned from a second fluid feed. The first and second fluid feeds are supplied to first and second input ports respectively of a mixing chamber located in the spray unit. Upon actuation of the side spray, fluid from the first and second fluid feeds can mix in the mixing chamber in the spray unit before being output. The mix ratio of the first and second fluid feeds may be adjustable.

  • Publication number: 20070158469
    Abstract: A method for stabilizing and centrally positioning an inner capillary in a concentric nebulizer comprises supporting the inner capillary near the tip of the nebulizer by contacting the nebulizer body against the inner capillary or by interposing a support between the nebulizer body and the inner capillary near the tip. An embodiment of a nebulizing device having stabilized central positioning of its inner capillary is disclosed which comprises an outer capillary with a linear bore and a gas/liquid orifice in a distal tip, a central capillary disposed within the linear bore, and a support sufficiently proximate the orifice to maintain the central capillary substantially centered within the outer capillary adjacent to the orifice. An open volume within the outer capillary between the orifice and the support is dimensioned to enable gas flow to spread substantially evenly around the central capillary.
