Patent CA-2189783-A1 (CA)
Title: Method and device for performing chemical reactions with the aid of microstructure mixing
Inventor: SCHUBERT KLAUS
IPC: B01J19/24
Filed: 1995-05-05
Abstract: In the proposed reaction process, at least two educts (A, B) are divided by their respective assemblies of microchannels (1a, 1b) into spatially separated fluid filaments. These fluid filaments then enter a common mixing and reaction chamber (4). It is essential that the fluid filaments of the two educts (A, B) are allowed to enter the mixing/reaction chamber (4) as free jets (6a, 6b), each free jet (6a) of an educt (A) being led into the mixing/reation chamber (4) immediately adjacent to a free jet (6b) of a different educt (B). Adjacent free jets then mix by diffusion and/or turbulence. This system significantly accelerates the mixing process by comparison with conventional reactors, and, with rapid chemical reactions, largely prevents the formation of unwanted by-products and secondary products.

Title: Method and apparatus for determining the location of a mobile telephone
Inventor: KAUSER NICOLAS
IPC: G01S19/48
Filed: 1997-01-21
Abstract: A method and apparatus for determining the location of a mobile telephone within the serving area of a mobile telephone system are disclosed. A mobile switching center analyzes the calling mobile telephone number and called telephone number to determine if a location function is required. Upon initiation of the location function by the mobile switching center, a mobile location module calculates a location estimate of the mobile telephone. The mobile location module receives a list of signal strengths received by the mobile telephone from cell site antennas within the serving area. The distance between the mobile telephone and a plurality of cell site antennas is calculated using a technique which reduces the error component of the calculated distances. These reduced error distances are used togeometrically determine an estimate of the location area. In addition, the mobile telephone comprises a GPS receiver/processor for sending the most recent GPS coordinates of the mobile telephone which are within a predetermined confidence level to the mobile location module. These GPS coordinates are compared with the calculated location area to increase the accuracy of the location determination.

Patent CA-2198148-A1 (CA)
Title: Geometric figures
Inventor: MILLER KLAUS
IPC: H03H1/00
Filed: 1996-05-28
Abstract: The problem addressed by the invention is that possible connections between circumstances which might exist in nature or technology and possible geometric figures cannot be exploited from the technical point of view, either because these geometric figures, for example, are not used for purposes for which they would be suitable or because circumstances which might exist for these geometric figures (such as, for example, marginal conditions) are not associated or because these geometric figures do not exist in these circumstances or because these geometric figures do not exist. Owing to their widely differing forms, their use in widely differing circumstances (e.g.  marginal conditions) and their widely differing application possibilities, these geometric figures may be connected with widely differing circumstances (such as, for example, geometric shapes of magnetic fields). These geometric figures have industrial applicability in the widest sense in the field of physical, chemical and biological technology. Band-stop filters and network filters constitute two possible embodiments of the claimed invention.

Title: Method of manufacturing silicon sulfide
Inventor: IKEDA NOBUHIKO
IPC: C01B17/20
Filed: 1997-04-14
Abstract: Silicon sulfide is manufactured from the fine powder of silicon covered thoroughly with sulfur at lower temperature less than 800°C in vacuum.      To produce the silicon sulfide, silicon should be ground in the non-oxidizing condition to prevent the formation of silicon oxide layer that should cause to retard the reaction or necessitate higher temperature.  The silicon powder is dispersed sufficiently in the molten sulfur.  At this time, the quantity of sulfur added needs more than 1.1 times in comparison with the stoichiometric quantity of silicon sulfide.      All surface of silicon powder should be covered with sulfur to avoid sintering between silicon particles in the process of heating.

Title: Process for control of electrodeposition utilizing cathodic and anodic flushable electrodes
Inventor: ALLSHOUSE W JAMES
IPC: C25D13/24
Filed: 1997-09-08
Abstract: An electrocoat application assembly is provided for controlling the pH and conductivity of an ionic coating solution. The assembly has a tank for containing the ionic coating solution with a first and second flushable tubular electrode assemblies located within the tank. The first and second electrode assemblies have an ionic membrane located in spaced relation from an electrode. A similar charge is then placed on the first and second electrodes. Further, the membrane of the first electrode has a charge corresponding to the charge of the electrodes and the ionic membrane of the second electrode has a charge opposite the charge on the electrodes. The oppositely charged membrane at the second electrode operates to remove ions having a charge opposite to that of the charge on the electrodes. An electrolyte circulation apparatus is provided for circulating an electrolyte solution through the first and second electrodes. Further, a process of controlling an ionic electrodeposition coating system is provided for a applying coating solution, which contains a solubilizer and ionic coating particles, to an object. A first flushable, tubular electrode is placed into the tank that is electrically charged and that is accessible by the solution through a correspondingly charged membrane. A second flushable, tubular electrode is also placed into the tank that is electrically charged corresponding to the first electrode and that is accessible by the solution through an oppositely charged membrane. The object to be coated is then supplied with an electrical charge, and the electrodes are supplied with an opposite electrical charge. The application of electrical current causes a portion of the ionic coating particles to be attracted to and deposited upon the object, and also causes a release of excess cations and anions. The ions that have a charge corresponding to the charge of the object are removed at the first electrode by allowing the ions to pass through its charged membrane. Further, the ions that have a charge opposite to the charge of the object are surprisingly attracted to the like-charged second electrode and are removed at the second electrode by allowing the ions to pass through its charged membrane. The excess cations and anions are then removed from the system by circulating an electrolyte solution through the flushable electrodes.
