Title: Thixotropic two-component polyurethane systems
Inventor: HILLER MICHAEL
IPC: C08G18/65
Filed: 1998-05-30
Abstract: The invention relates to two-component polyurethane systems, consisting of one polyol component and one isocyanate component. Said polyol component contains at least two amines A1 and A2, the reactivity R1 of amine A1 with isocyanate being considerably greater than the reactivity R2 of amine A2 with isocyanate. As a result, two time-delayed reactions take place. This gives the inventive systems the desired low level of viscosity, and the thixotropic properties which prevent even thick layers from sliding off of vertical surfaces. The inventive two-component polyurethane systems can be used for producing cubing models, master models and similar in the automobile industry and for producing structured bodies and thick films and sealing beads.

Title: A vocoder-based voice recognizer
Inventor: HERSHKOVITS YEHUDA
IPC: H04W88/02
Filed: 1998-07-22
Abstract: A vocoder based voice recognizer recognizes a spoken word using linear prediction coding based vocoder data without completely reconstructing the voice data. The recognizer generates at least one energy estimate per frame of the vocoder data (60) and searches for word boundaries in the vocoder data (64) using the associated energy estimates. If a word is found (66), the linear prediction coding word parameters are extracted (68) from the vocoder data associated with the word and recognition features are calculated (70) from the extracted linear prediction coding word parameters. Finally, the recognition features are matched with previously stored recognition features of other words (40), thereby recognizing the spoken word.

Patent CA-2307656-A1 (CA)
Title: Reactions of aromatic compounds
Inventor: BURNS JOHN
IPC: C07C205/06
Filed: 1998-11-05
Abstract: A method of reacting an aromatic compound with an immiscible reacting agent involves the passage of the reactant along a flow path having a width of from 10 to 1000 µm in such a way that essentially laminar flow of the reactant takes place. Reaction takes place across the interface between the phases and without substantial mixing of the unreacted aromatic compound and the reacting agents. A  preferred reaction is the nitration reaction which involves reaction of a first phase comprising an organic aromatic compound on a second phase comprising a nitrating agent to produce two new phases of different chemical composition to the starting phases. The aqueous and organic phases produced are ideally separated such that minimum contamination occurs. Other examples of this type of reaction include the sulphonation of an aromatic compound using sulphuric acid as the sulphonating agent. The aromatic compound is slowly consumed in the reaction yielding a single aqueous phase.

Patent CA-2312713-A1 (CA)
Title: Enhanced ngl recovery processes
Inventor: ELLIOT DOUGLAS G
IPC: F25J3/02
Filed: 1998-12-01
Abstract: The present invention is directed to methods for improving the efficiency and economy of processes for the recovery of natural gas liquids (NGL) from a gas feed, e.g., raw natural gas or a refinery or petrochemical plant gas stream. These methods may be employed with most, if not all, conventional separation methods using a distillation tower, e.g., a demethanizer or deethanizer column. In the methods of the present invention, a portion of a hydrocarbon liquid condensed on a chimney tray disposed below the lowest feed tray of the column is withdrawn from the tower. This withdrawn liquid hydrocarbon is expanded and heated to produce a two-phase system for separation into a heavy, liquid hydrocarbon product and a vapor phase for recycle to the column, preferably as a stripping gas. The withdrawn hydrocarbon liquid is preferably heated by indirect heat exchange with the inlet gas, thus reducing or eliminating the external refrigeration requirements of the process. The expanded, heated vapor recycled to the column increases the ethane and propane concentration in the column, this reducing the tray temperature profile and increasing the separation efficiency. Accordingly, the column may be operated at lower temperatures and higher pressures, resulting in significant energy savings and economies of operation.

Title: Methods and systems for bioremediating contaminated soil
Inventor: RICHTER ROGER TODD
IPC: B09C1/06
Filed: 1998-10-15
Abstract: A system and method for remediation of contaminated soil removed from a soil site is provided. The contaminated soil is placed upon several layers of perforated heating pipes forming a remediation cell, and the entire cell is covered by a galvanized Quonset Hut-shaped steel building to prevent the escape of vapors from the soil cell. Heating air introduced into perforated heating pipes heats conductively the contaminated soil orating a differential pressure area around the heated pipes. This results in the migration of volatilized contaminants and moisture through the perforations in the pipe walls and into the lower pressure area within the heated steel pipes, forcing the contaminants from the soil and into an off-gas treatment system.

Patent CA-2320533-A1 (CA)
Inventor: KOLSRUD ARILD
IPC: H04W72/04
Filed: 2000-09-25
Abstract: A method and apparatus for properly receiving communication signals having relatively high dynamic ranges. The communication signals are transmitted by equipment of a communication system. A receiver comprising a plurality of filters each of which represents a frequency band is used to receive the communication signals. Each frequency band is assigned a specific dynamic range. A controller coupled to the receiver determines the amplitude of the received signals. The controller is also coupled to a call processing module. The controller also determines whether the received signal is in the proper frequency band; that is whether the amplitude of the received signal is within the assigned dynamic range of the frequency band within which the signal is transmitted. When the signal is not in the proper frequency band, the controller in conjunction with the call processing module transmit a message to the equipment that transmitted the received signal instructing the equipment as to which frequency band to transmit the signal.

Title: Injection laser
Inventor: SHVEIKIN VASILY IVANOVICH
IPC: H01S5/185
Filed: 1999-08-05
Abstract: The present invention relates to an injection laser in which the optical resonator has a particular structure. The volume of the optical resonator medium includes an amplification area active volume for an intensive outlet amplification as well as a passive volume for the radiation inlet area (7). The volumes include a number of layers that form a laser heterostructure (2)  and have compositions and thicknesses determined correspondingly. The optica l faces (8, 9) of the radiation inlet area (7) have different configurations, while said laser further uses ohmic contacts (15, 16). It is thus possible t o essentially determine the formation area of the laser radiation modes as wel l as the injection area of non-equilibrium carriers and of their stimulated recombination. It is also possible to increase the power of the laser radiation, to reduce the current threshold density, to increase the laser efficiency and to obtain reduced divergence angles which are close to the diffraction angle for two mutually perpendicular outlet directions of the radiation. It is further possible to increase the regularity of the single- mode generation process, to improve the spatial-spectral characteristics, to  substantially reduce the wavelength dependency of the laser radiation generated on the amplitude of the pumping current, and to increase the servi ce duration as well as the operation reliability. This invention also relates t o highly efficient lasers having a laser radiation outlet which is perpendicul ar to the plane of the active layer, as well as to lasers having powerful laser  beams with the autonomous activation thereof.
