20110183065 | Methods and apparatus for roll-coating sheet articles using metering roll of variable profile - Methods and apparatus for coating a major surface of a strip article advancing past and in contact with an applicator roll by supplying coating material to the applicator roll for transfer to the strip surface while urging a metering roll against the applicator roll to impart a coating profile to the coating material on the applicator roll before the coating material having that profile is transferred to the strip surface, wherein the metering roll is subjected to a force for bending the axis of the metering roll convexly toward the applicator roll, thereby to compensate for deflection of the metering roll that would otherwise tend to cause nonuniformity of applied coating weight across the width of the strip. | 07-28-2011 |

20130280485 | Superhydrophobic and Oleophobic Functional Coatings Comprised of Grafted Crystalline Polymers Comprising Perfluoroalkyl Moieties - Described herein are methods of preparing superhydrophobic and oleophobic surfaces by grafting poly(perfluoroalkyl acrylate) chains on silicon substrates with initiated chemical vapor deposition. The grafting enhances the formation of the crystalline phase. The crystalline structures reduce the polymer chain mobility, resulting in nonwetting surfaces with respect to both water and mineral oil. | 10-24-2013 |

20090145296 | Angled slot foam dispenser - The present invention provides a piston pump for liquid in which a sump is defined in a chamber into which sump liquid in the chamber flows due to gravity. A passageway leads from an outlet of the sump out of the chamber to a dispensing outlet. The dispensing outlet is at a height below the height of the sump outlet and fluid to exit the sump flows from the sump outlet upwardly in a first portion of the passageway to a height above the sump outlet then downwardly to the dispensing outlet. The chamber and its sump is defined between a piston chamber-forming member defining the chamber to be downwardly opening and a piston forming element axially slidable in the chamber. | 06-11-2009 |
20100140297 | Engagement flange for fluid dispenser pump piston - An improved arrangement for removably coupling a movable element of a piston pump to an actuator mechanism with the movable element including a resilient member which prevents radial movement of the movable element relative a catch member of the actuator mechanism from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration. | 06-10-2010 |
20100163580 | Engagement flange for removable dispenser cartridge - An improved arrangement for removably coupling a replaceable cartridge to a housing of a dispenser with the cartridge including a resilient member which prevents radial movement relative a catch member of the housing from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration. | 07-01-2010 |
20110014076 | Draw back push pump - A piston pump dispenser having a reciprocating piston pump arrangement which in a dispensing stroke dispenses fluid from an outlet and in a charging stroke draws fluid from a reservoir and also draws back fluid from the outlet. | 01-20-2011 |
20110132933 | Piston with frangible piston stop - A piston pump assembly in which a piston-forming element to be received in a piston chamber of a piston chamber-forming member carries a removable stop flange member which may be secured to the piston chamber-forming member to provide a retention stop to prevent the piston-forming element from being removed from the piston chamber. | 06-09-2011 |
20130233167 | PISTON WITH FRANGIBLE PISTON STOP - A piston pump assembly in which a piston-forming element to be received in a piston chamber of a piston chamber-forming member carries a removable stop flange member which may be secured to the piston chamber-forming member to provide a retention stop to prevent the piston-forming element from being removed from the piston chamber. | 09-12-2013 |
20140099224 | VARIABLE VOLUME BORE PISTON PUMP - A piston pump which permits advantageous operation over both short stroke piston movement and long stroke piston movement. | 04-10-2014 |
20160097386 | Displacement Pump - A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump. | 04-07-2016 |

20090106203 | METHOD AND APPARATUS FOR A WEB SEARCH ENGINE GENERATING SUMMARY-STYLE SEARCH RESULTS - A method and apparatus for a summarization-based search engine is presented. This invention provides a concise answer to a user's query—an accurate and up-to-date summary—that is synthesized from multiple contents taken from the World Wide Web. In contrast to conventional search engines, such as Google and Yahoo!, which return the user a list of web links, page titles and sentence fragments, this invention generates more readable, informative, relevant and integrated answers in response to the user's query. Moreover, this invention has broad applications to different search platforms and specific domains. It particularly suits well for mobile devices, inasmuch as its results are more concise than those of conventional search engines. | 04-23-2009 |
