Title: Method for encapsulating dissolved color reaction partners of color reaction systems, the capsules obtained according thereto, and their use in color reaction papers
Inventor: PIETSCH GUNTER
IPC: B01J13/16
Filed: 2003-09-18
Abstract: The invention relates to a method for encapsulating a solution, which consists of color reaction partners of color reaction systems while being provided in an aqueous emulsion, by using conventional microencapsulation methods.  According to the invention, the color reaction partner is firstly dissolved in a solvent, and a nonsolvent that, at most, slightly dissolves the color reaction partner is admixed with rapid mixing to the solution obtained in the aforementioned manner. The nonsolvent is admixed in an amount that results in a supersaturated solution. The supersaturated solution is immediately emulsified with rapid mixing in the aqueous phase, and the encapsulation is carried out immediately afterwards. A vegetable oil C1-C8 alkyl ester is used in the solvent. This method exhibits both economic and technological advantages while enabling the production of microcapsules having an advantageously tight monomodal particle distribution that leads to an improved print rate.

Title: Online source reconstruction for eeg/meg and ecg/mcg
Inventor: FUCHS MANFRED
IPC: A61B5/308
Filed: 2004-01-27
Abstract: In one embodiment, the present invention includes an EEG system comprising of sensors which are utilized to gather an electromagnetic signal from a patient;  a signal processing system; and a computer system. The computer system is configured to support multiple threads of execution. The computer system initiates a first thread of execution, a measurement module, where the data is filtered and in some cases averaged. Typically, the data is filtered for a particular latency period. Once the data has been filtered and averaged, the result is given to a second thread of execution, the source reconstruction module, which then proceeds to generate a source reconstruction for the trial.  The measurement module then acquires and processes new electromagnetic data from a new trial while the source reconstruction is being performed on the most recent trial.

Title: Method and roll stand for multiply influencing profiles
Inventor: ROHDE WOLFGANG
IPC: B21B13/00
Filed: 2004-11-22
Abstract: When rolling sheets or strips in roll stands using working rolls, which are supported on back-up rolls or on intermediate rolls having back-up rolls, whereby the setting of the roll gap is effected by axially displacing roll pairs provided with curved contours, differences from the required profile occur in the instance of larger widths of a product range due to excessive extensions in the edge areas or in the quarter areas that are manifested in the form of so-called quarter waves in the flatness of the product. In order to rectify this problem by using a simple mechanism and to improve the setting mechanism and the strategy for creating absolutely planar strips with a predetermined thickness profile over the entire width of the rolling stock, the invention provides that for forming the roll gap set profiles (10, 11) for two selected displacing positions, the contours of the rolls of one roll pair are shaped in such a manner that they produce, in the roll gap, a profile (20, 21), which is symmetric with regard to the center of the roll and which has a profile maximum in the center of the roll that can be altered by displacing the rolls, whereas the contours of the rolls of at least one second roll pair produce, in the roll gap, a profile (22, 23), which is symmetric with regard to the center of the roll and which has two identical maxima outside of the center of the roll that can be altered by displacing the rolls.

Abstract: The invention relates to a die cavity of a casting die for continuously casting billets, blooms and blanks, steel being cast in a die cavity having a cross-section with a partially curved peripheral (42) line, and cavity walls cooled. The aim of the invention is to create optimum conditions for a regular heat exchange between a forming strand shell and the die cavity wall along the peripheral line (42) of the strand cross-section, and to avoid solidification defects in the strand shell. To this end, the degree of curvature 1/R is reduced at least on part of the curved peripheral line (42) of the corner regions from peripheral lines (42', 42") of the same corner regions, that are successive in the casting direction, and at least over part of the length of the die, in the concave corner regions of the die cavity, in order to control the targeted closure of the gap between the strand shell and the cooled die cavity, or a targeted strand shell deformation.

Patent CA-2549614-A1 (CA)
Inventor: NENNIGER JOHN
IPC: E21B43/24
Filed: 2006-06-07
Abstract: A process for recovering hydrocarbons from an in situ formation. The process includes the steps of injecting steam though an injection well into an underground extraction chamber having a hydrocarbon extraction interface, warming the hydrocarbons at the extraction interface to cause the hydrocarbons to flow downwardly by gravity drainage and to release dissolved hydrocarbon gases and moving the hydrocarbon gases from the extraction interface to improve heat transfer from said steam to said interface. The last step is to recover liquids such as hydrocarbons and water through a production well. The invention provides adding a buoyancy modifying agent to the steam to cause the hydrocarbon gases to accumulate in the well in a preferred location. The preferred location is at the top of the chamber where the gases protect the top of the chamber from being extracted to the point of breakthrough.
