Title: Well treating compositions containing water-superabsorbent material and method of using the same
Inventor: QU QI
IPC: C09K8/90
Filed: 2006-03-10
Abstract: A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a crosslinking agent, brine and/or a viscosifying polymer or a gelling agent. As an oil-based fluid, the crosslinking agent is absorbed onto the water-superabsorbent material and serves to effectively delay crosslinking.

Title: Method and device for determining the actual position of a geodetic instrument
Inventor: EULER HANS-JUERGEN
IPC: G01C11/04
Filed: 2004-09-09
Abstract: Method for determining the actual position (A) of a geodetic measurement instrument (1) within a dead area (T) in which signals from a positioning system are shadowed out. Accordingly at least two reference structures (5) are measured from at least two known positions and the distances to the reference structure measured. The distance measurements are linked with image information relating to the layout of the reference structures. Subsequently the reference images are measured from the dead area and the actual positions derived. The invention also relates to a device for the actual position of a geodetic measurement instrument within a dead area. Advantageously image processing techniques are used to identify and measure the reference structures.

Title: Method and apparatus for converting heat into mechanical work
Inventor: HIRSCHMANNER RUDOLF
IPC: F02C1/10
Filed: 2004-11-18
Abstract: The invention relates to a method for converting heat into mechanical work according to which, in a cyclic process, a working medium is compressed while giving off heat and is subsequently brought in thermal contact with the surroundings via a first heat exchanger (16), is then expanded while obtaining mechanical work whereupon the cyclic process is run through once more. A high degree of efficiency is achieved by virtue of the fact that the working medium, after expansion, is guided through another heat exchanger (18), which is situated inside a rapidly rotating rotor (13) and which, on the exterior thereof, is surrounded by at least one essentially annular gas space (17a, 17b, 17c, 17d) from whose exterior heat is dissipated. The invention also relates to a device for carrying out this method.

Patent CA-2560224-A1 (CA)
Inventor: RICCI STEFANO
IPC: A61K39/095
Filed: 2005-03-17
Abstract: The invention is based on methods that allow analysis of mixed meningococcal saccharides from multiple serogroups even though they share monosaccharide units. With a combination of saccharides from serogroups C, W135 and Y, the invention analyses sialic acid, glucose and galactose content. The glucose and galactose results are used to directly quantify saccharides from serogroups Y  and W135, respectively, and the combined glucose and galactose content is subtracted from the sialic acid content to quantify saccharides from serogroup C. The three serogroups can thus be resolved even though their monosaccharide contents overlap. The three different monosaccharide analyses can be performed on the same material , without interference between the monosaccharides and without interference from any other saccharide materials in the composition (e.g. lyophilisation stabilisers). The method can be used to analyse total and free saccharide in conjugate vaccines and simplifies quality control of vaccines containing capsular saccharides from multiple serogroups.

Abstract: A wet-style cylinder liner (16) for a diesel engine is provided with a surface texture (28) to combat the effects of cavitation-induced erosion. The surface texture (28) can be formed as a coating (30) of manganese phosphate applied about the outer surface (26) of the cylinder liner (16) within the coolant flow passage (20) of the engine. The manganese phosphate is applied in such a manner that a crystalline structure of 2-8~m average grain size, blocky in nature, clearly faceted, with no cauliflower-like formations and a discernable channel network surrounding the crystals is formed. This crystalline structure works with the natural adhesion and surface tension effects within the liquid coolant to create a stagnant fluid layer about the outer surface (26) of the cylinder liner (16). The stagnant fluid layer functions like a self-healing armor plate. When rapid flexing of the cylinder liner (16) produces cavitation bubbles, these bubbles are held at a distance from the outer surface (26) by the stagnant fluid layer. As the bubbles implode, their kinetic energy is dissipated within the stagnant fluid layer instead of directly upon the outer surface (26) of the cylinder liner (16). The manganese phosphate coating (30) acts as a labyrinth to anchor water molecules, or the engine coolant, and thus promote formation of the stagnant fluid layer.
