20090191335 | Method for the continuous coating of the inside of an extruded hollow profiled member - A method for continuously coating the inside of a continuously extruded hollow profiled bar made of elastic material and a liquid wiper and a device for removing excess coating agent from the chambers of a hollow profiled member. A hollow profiled bar is directed through a stationary supply of a liquid coating agent on a bent, arc-shaped track, whereby inner walls of the hollow profiled bar are moistened with coating agent, and the hollow profiled bar is guided along a rising track directly after running through the coating agent supply. Excess coating agent is wiped off one or plural inner walls with the aid of liquid wipers mounted inside the hollow chambers, the hollow profiled bar being continuously moved relative to the liquid wipers. The liquid wipers include at least one magnet or magnetizable material and a wiping lip that touches the inner walls while being located downstream of the coating agent supply in a zone of a sloped track of the hollow profiled bar. The liquid wipers are retained in a steady position within the track of the hollow profiled bar with the aid of counter magnet or magnetizable materials that are fixed next to the outer surface of the continuous hollow profiled bar. | 07-30-2009 |
20100112207 | Process for thermal spraying the internal surface of a kort nozzle in situ - The present invention is directed to a process and apparatus for thermally spray coating the inside surface of a hydro-drive device, namely a Kort, so as to improve hydro-flow thrust and reduce the consumption of fuel for a vessel comprising the adapted Kort. The process of the present invention comprises thermally spraying a thermoplastic material in the area of the interior wall of the Kort that comes in close proximity to the propeller of the hydro-drive device. The closer the propeller comes to the interior wall of the Kort, the less friction and cavitations produced. Since friction and cavitations increases fuel consumption of the vessel, any reduction in the clearance between the wall of the Kort and the propeller tips directly reduces fuel consumption. At the same time, a reduction in clearance also increases the thrust of the hydro-drive device. | 05-06-2010 |

20120070574 | PRETREATMENT METHOD FOR IMPROVING ANTIOXIDATION OF STEEL T91/P91 IN HIGH TEMPERATURE WATER VAPOR - Disclosed is a pretreatment method for improving antioxidation of steel T91/P91 in high temperature water vapor, which includes applying a slurry, containing rare earth oxide, on a surface of a substrate; holding the temperature in a gas mixture environment of inert gas and water vapor after drying; and cleaning away the solid powder left by the slurry on the surface, thereby obtaining the substrate with a surface rich in chromium and having a small amount of rare earth oxide. As a result of the method, the antioxidation capability of steel T91/P91 in the 500-750° C. water vapor environment can be improved, and films rich in chromium oxide can be formed on the surface of steel T91/P91. | 03-22-2012 |

20140057048 | METHOD OF MAKING IONIC LIQUID MEDIATED SOL-GEL SORBENTS - Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics. | 02-27-2014 |
