Patent number: 8322630Abstract: A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. A bimodal distribution of particle sizes is obtained under two different operating conditions. The sprayer/liquid combination according to the present invention compresses the difference between the two modes, without requiring undue work by the operator. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.Type: GrantFiled: May 10, 2010Date of Patent: December 4, 2012Assignee: The Procter & Gamble CompanyInventors: James Samuel Richardson, Robin Lefebvre, Victor Klabbers, Elizabeth Jackson Glass, Michael Alan John Moss, Mitsuaki Shaduki

Some water hits the inwall of the spherical cavity and then reflects back to be reflection water. The reflection water impacts other water to turn to the side flowing down along the wall of the outlet. Due to the unstability of effluent, the water stream is along one place, turning to another side the next moment. So that the water sprays as a periodic and circumferential pulsed water.Type: ApplicationFiled: January 7, 2011Publication date: July 12, 2012Applicants: XIAMEN SOLEX HIGH-TECH INDUSTRIES CO., LTD.Inventors: Yangfeng Ji, Jianmin Chen, Liangwei Wang, Huasong Zhou

Publication number: 20110121109Abstract: A fiber preform obtained by conforming panels of fiber texture on a former having a surface that reproduces the shape desired for a surface of the nozzle or the nozzle divergent section that is to be made, and by bonding the panels together via their mutually contacting edges, and consolidated fiber reinforcement is formed by shaping the fiber preform impregnated with a consolidation composition comprising a resin, shaping being performed between the former and a jacket applied against the impregnated fiber preform so as to obtain consolidated fiber reinforcement having a fiber volume percentage of at least 35%, and having a thickness of no more than 5 mm over at least a major fraction of its axial dimension. The densification of the fiber reinforcement is continued by chemical vapor infiltration after pyrolyzing the resin so that once densified a part is obtained that has practically the shape and the wall thickness of the nozzle or the nozzle divergent section that is to be made.Type: ApplicationFiled: July 13, 2009Publication date: May 26, 2011Applicant: SNECMA Propulsion SolideInventors: Francois Charleux, Jean-Marie Parenteau, Bernard Delperier

Patent number: 7938079Abstract: Method and apparatus for improved maskless deposition of electronic and biological materials using an extended nozzle. The process is capable of direct deposition of features with linewidths varying from a few microns to a fraction of a millimeter, and can be used to deposit features on targets with damage thresholds near 100° C. or less. Deposition and subsequent processing may be performed under ambient conditions and produce linewidths as low as 1 micron, with sub-micron edge definition. The extended nozzle reduces particle overspray and has a large working distance; that is, the orifice to target distance may be several millimeters or more, enabling direct write onto non-planar surfaces. The nozzle allows for deposition of features with linewidths that are approximately as small as one-twentieth the size of the nozzle orifice diameter, and is preferably interchangeable, enabling rapid variance of deposited linewidth.Type: GrantFiled: December 13, 2004Date of Patent: May 10, 2011Assignee: Optomec Design CompanyInventors: Bruce H.
