The member 39 has chamfers 46, 47 which engage the top 21 of the valve cup when the stem 18 is tilted to open the valve. The member 39 has a locating detent 52 for the member 24 and a flat front 37, which front is engageable by a slidable actuator 60, Fig. 8, when cans fitted with caps are mounted in a dispenser 57 of the type described in Specification 1332627, the flat front and chamfers operating to align the caps correctly.

Reduced blockage atomiser

A non fouling atomiser includes vessel 8 with outlet tube 7 and atomiser assembly which consists of tube 2 with optional disc 11 and a number of small holes 3. The material to be atomised 9 is placed in the vessel 8 and a supply of compressed gas 1 used to produce high velocity jets (4, Fig 1). The holes are placed and sized to form jets which interact with each other to create high levels of turbulence which produce energetic mixing, droplet formation, fluidisation or reactions. Unlike atomisers which require a dip leg tube, the design is non fouling because no liquid passes through the small holes and can therefore be used to atomise liquids containing solids such as crystals or powders as well as clean liquids. In combustion applications the invention produces intense secondary mixing eliminating the need for pre-mixing of combustion gases.

Combustion analyser sample introduction apparatus and method

A combustion analyser sample introduction apparatus and method for supplying a liquid sample into a combustion chamber (130,150) of a combustion analyser. A supply spray head 92 is received in the member end and comprises a discharge opening 94 to deliver liquid sample and carrier gas into the combustion chamber. A carrier gas supply conduit 106 (114, 122) supplies carrier gas (preferably, oxygen) to the discharge opening, along a carrier gas flow path. A sample supply conduit 100 having a downstream first end passes through the supply member towards the spray head and supplies liquid sample, via channel 102, into the carrier gas flow path at a sample supply location within the combustion chamber at/adjacent the discharge opening. Liquid sample is thereby transported by carrier gas out of the discharge opening and into the combustion chamber as a spray.

A shower head

The shower head is composed of a spray head disposed at the forward end of a spray housing, a distributor disposed in the spray housing and having first and second supply openings, and a selector. By rotating the spray housing, the selector can be moved axially in the distributor. The shower head also has a first chamber disposed at the forward end of the distributor, a straight spray nozzle disposed at the forward end of the first chamber, and a needle valve. The needle valve can be slid in the first chamber and is composed of a needle and a circular plate resiliently urged to a closed position. Only when the selector pushes forward the circular plate to provide a straight spray does the straight spray nozzle communicate with the inside of the distributor. In other cases the distributor is closed by the circular plate so that the inside of the shower head is protected from dust or other foreign particles.

Sootblower nozzle

A nozzle (16) for a sootblower (10) is used to project a cleaning agent against the internal surfaces of a boiler for removing fireside deposit. The nozzle of the present invention incorporates a passageway having a convergent segment between its entrance end (49, 73) and its most narrow point, the throat (47, 77). Extending from the throat to the nozzle's exit is an expansion chamber (51, 82) in which the cleaning fluid passing therein expands and drops in pressure to substantially ambient pressure. The flow stream of the jet of the cleaning agent discharged from the nozzle is essentially parallel to the center axis of the nozzle. Additionally, the nozzles can be mounted diametrically opposed or spaced along the longitudinal axis of the lance tube (201). Moreover, the nozzles mounted in a lance tube can be mounted flush with the outside surface of the lance tube, contoured to its shape.

An atomizer comprising a non-wetting surface having a dynamic contact angle of at least about 90° , said surface patterned with macro-scale features configured to induce controlled asymmetry in a liquid film produced by impingement of a droplet onto the surface , thereby promoting breakup of the droplet on the surface.44. The atomizer of claim 43 , wherein the non-wetting surface is supermetallophobic.45. The atomizer of claim 43 , wherein the droplet comprises a molten metal. This application claims priority to and the benefit of, and incorporates herein by reference in its entirety U.S. Provisional Patent Application No. 61/514,794, which was filed on Aug. 3, 2011.This invention relates generally to surfaces that manipulate impinging liquids. More particularly, in certain embodiments, the invention relates to macro-scale features on a surface that reduce the contact time between an impinging liquid and the surface.Superhydrophobicity, a property of a surface when it resists contact with water, has been a topic of intense research during the last decade due to its potential in a wide variety of applications, such as self-cleaning, liquid-solid drag reduction, and water repellency. Water repellency of superhydrophobic surfaces is often studied by droplet impingement experiments in which millimetric drops of water are impacted onto these surfaces and photographed. With appropriate surface design, droplets can be made to bounce off completely. However, the time taken to bounce off—hereafter referred to as the contact time—is critically important as mass, momentum, and/or energetic ...
