Abstract: 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.

Abstract: A novel on-line method is presented for the extraction and preconcentration of amino acids using a sol-gel coated column coupled to a conventional UV/vis detector. Extraction, stacking and focusing techniques are used in the preconcentration procedures. Sol-gel coatings are created by using N-Octadecyldimethyl[3(trimethoxysilyl)proply] ammonium chloride (C18-TMS) in the coating sol solutions. The resulting sol-gel coating carries a positive charge. For extraction, the pH of the samples is properly adjusted to impart a net negative charge to amino acids. A long plug of the sample is then passed through the sol-gel coated capillary to facilitate extraction via electrostatic interaction between the positively charged sol-gel coating and the negatively charged amino acid molecules. The focusing of the extracted amino acids is accomplished through desorption of the extracted amino acid molecules carried out by local pH change. The described procedure provides 150,000-fold enrichment effect for alanine.
