Title: Dry high flux semipermeable membranes
Inventor: CHAU MICHAEL M
IPC: B01D69/12
Filed: 1990-11-30
Granted: 2000-05-23
Abstract: High flux semipermeable membranes which comprise the polymerized reaction product within and/or on a porous support backing material may be prepared by contacting the porous support such as a polysulfone with an aqueous solution of a polyamide which may, if so desired, contain a polar aprotic solvent not reactive with the amines, a polyhydric compound and an acid acceptor. The surface of the coated support is freed of excess solution and thereafter contacted with an organic solution of a polyacyl halide for a period of time sufficient to form a polymerized reaction product within and/or on the support material. The resulting composite is then treated with a hydroxy polycarboxylic acid, polyaminoalkylene polycarboxylic acid, sulfonic acid, amine salts of acids, amino acid, amino acid salt, polymeric acid and inorganic acid, before drying of the membrane. This will enable the membrane to be stored in a dry manner prior to use thereof in a separation process. The resultant membrane composite may be used in separation processes such as desalination of brackish or sea water or the softening of domestic hard water,

Patent CA-2074418-C (CA)
Inventor: HERMANSKY HYNEK
IPC: G10L19/06
Filed: 1992-07-22
Granted: 1995-12-12
Abstract: A method for synthesizing human speech using a linear mapping of a small set of coefficients that are speaker-independent. Preferably, the speaker-independent set of coefficients are cepstral coefficients developed during a training session using a perceptual linear predictive analysis. A linear predictive all-pole model is used to develop corresponding formants and bandwidths to which the cepstral coefficients are mapped by using a separate multiple regression model for each of the five formant frequencies and five formant bandwidths. The dual analysis produces both the cepstral coefficients of the PLP model for the different vowel-like sounds and their true formant frequencies and bandwidths. The separate multiple regression models developed by mapping the cepstral coefficients into the formant frequencies and formant bandwidths can then be applied to cepstral coefficients determined for subsequent speech to produce corresponding formants and bandwidths used to synthesize that speech. Since less data are required for synthesizing each speech segment than in conventional techniques, areduction in the required storage space and/or transmission rate for the data required in the speech synthesis is achieved. In addition, the cepstral coefficients for each speech segment can be used with the regressive model for a different speaker, to produce synthesized speech corresponding to the different speaker.

Abstract: A device operates a swirling device which controls the flow rate of combustion air of a burner for gas turbine engines. At the head end of a combustion chamber, a ring body which is arranged coaxially with respect to the fuel nozzle is to have swirling ducts whose cross-sections are controllable by duct walls of a ring which is axially displaceable on the ring body. The axial displacement of the ring is to take place by means of a control piston which is axially displaceable in a housing, is spring-loaded on one side, is also actuated by a valve-controlled pressure difference existing on the spring side between an ambient pressure and a primary air pressure, controls openings communicating with the valve and the head end of the combustion chamber, and is acted upon on piston surfaces, which are free with respect to the housing, on the one side, by a pressure of supplied primary air existing at the head end and, on the other side, by the chamber pressure existing at the burner.

Abstract: The present invention is concerned with a real time slope monitoring system to improve safety and optimize design of for rock or soil excavation activities by continuously scanning the movement of rock and soil slopes, civil structures and land masses. The scanning is realized by systematically tracking the movement of strategically placed targets (prisms) using EDM equipped robotic theodolites. The system comprises two elements: a remote station and a base station. The remote station consists of a computer that controls the robotic theodolite which shoots a defined series of targets. The data is then transmitted to the base station computer for data manipulation and real time graphics display. The system of the present invention can contain more than one remote station.

Abstract: 2106006 9216394 PCTABS00016 The restraint (210) device includes an open ended tubular guide member (215) which is generally cylindrical or elliptical in cross-section and in which the interior surfaces (235) of the tubular member define a longitudinal passageway for receiving and engaging portions of both the shoulder harness (S) and lap portions (6) of a three-point vehicular restraint system. The guide member (215) exerts a laterally displacing force on the shoulder harness portion (S) of a three-point restraint system to re-orient the shoulder belt for use by adults of relatively small stature or children. In this manner, the repositioning of the shoulder belt (S) for use by children in particular may be accomplished without adversely displacing the relative position of the lap belt (L) particularly during impact conditions. The advantages of the restraint device are accomplished without adversely affecting the automatic adjustment capabilities of the existing automotive restraint apparatus or without requiring extensive modifications to the existing restraint.

IPC: C07C29/152
Filed: 1993-11-30
Granted: 2004-08-10
Abstract: The purge gas from a methanol synthesis loop is subjected to a further step of methanol synthesis, preferably while in indirect heat exchange with the purge gas undergoing heating to the synthesis inlet temperature so that the reacted purge gas, containing synthesised methanol, leaves the synthesis catalyst at a temperature below the maximum temperature achieved by the reacting purge gas during passage over the catalyst.      The synthesis loop can be operated less efficiently, eg at a lower pressure or with added carbon dioxide, than is conventional since the additional methanol produced from the purge gas compensates for the loss of loop efficiency.      The addition of the purge gas synthesis stage enables existing plants to be uprated by lowering the loop pressure, thus enabling a greater throughput through the synthesis gas compressor to be achieved.
