IPC: C09K8/575
Filed: 2003-05-27
Abstract: Methods of consolidating formations or forming chemical casing or both while drilling are provided. One method of the invention comprises drilling a well bore with a drilling fluid comprised of water, a polymeric cationic catalyst which is adsorbed on weak zones or formations formed of unconsolidated clays, shale, sand stone and the like, a water soluble or dispersible polymer which is cross-linked by a thermoset resin and causes the resin to be hard and tough when cured, a particulate curable solid thermoset resin, a water soluble thermoset resin, and a delayed dispersible acid catalyst for curing the solid and water soluble resins. The drilling fluid forms a filter cake on the walls of the well bore that cures and consolidates the unconsolidated weak zones and formations penetrated by the well bore so that sloughing is prevented and forms a hard and tough cross-linked chemical casing on the walls of the well bore.

Title: A method of determining the risk of ice deposition due to precipitation and apparatus for exercising the method
Inventor: NIELSEN EVAN
IPC: G01W1/10
Filed: 2003-08-26
Abstract: The invention relates to a method and an apparatus for determining the risk of ice deposition due to precipitation. According to the invention the measurements of precipitation known so far are combined with measurements of the actual amount of ice deposited from the precipitation. Said measurements are combined in a combination unit that is able to receive further parameter information, eg the amount and type of anti-icing liquid. Compared to previously a considerably more reliable determination of the risk of ice deposition is accomplished, eg on the wing of an aeroplane applied with anti - icing liquid, and so is reliable determination of the holdover time, HOT, during which one can be sure that the aeroplane is free from ice in the current weather conditions.

Abstract: Disclosed are a multi-chip power amplifier comprising a plurality of chips (20-23) with each chip being a transistor amplifier, and a housing (36) in which all of the semiconductor chips are mounted. A plurality of input leads extend into the housing and a plurality of output leads extend from the housing. A  plurality of first matching networks (38) couple a semiconductor chip to an input lead and a plurality of second matching networks (40) couple each semiconductor chip to an output lead whereby each chip has its own input lead and output lead. By providing all amplifier chips within a single housing with matching networks within the housing coupling the chips to the input and output leads, manufacturing cost is reduced and the overall package footprint on a mounting substrate is reduced. Further, the close proximity of the chips within the housing reduces phase differences among signals in the semiconductor chips.

Abstract: Method for the detection of a pathogenic form of a prion protein in a sample, comprising providing a container, pretreating the container to deposit on a surface of the container a coating of a cellulose derivative capable of favoring the binding of pathogenic prion protein to said container surface over the binding of cellular prion protein, incubating the sample in said container to bind any pathogenic prion protein present in the sample to said container surface, labelling the thus immobilized pathogenic prion protein, if present, with an appropriate labelling agent using an anti-prion antibody capable of binding to pathogenic prion protein and detecting the presence of labelling agent attached to the container surface. Coating a surface of a microtitre plate well with nitrocellulose allows to perform an ELISA for quantification of pathogenic prions in a suspected sample, especially after enzymatic digestion of the sample with an enzyme like proteinase K, by enhancing binding of pathogenic prions and/or reducing binding of cellular (non-pathogenic) prions.
