Title: Supported pervaporation membrane and module containing arrays of membranes
Inventor: LIPSKI CHRISTOPHER J
IPC: B01D69/10
Filed: 1991-10-01
Abstract: SUPPORTED PERVAPORATION MEMBRANE AND MODULE        CONTAINING ARRAYS OF MEMBRANES                 ABSTRACT OF THE DISCLOSURE A pervaporation membrane comprises a porous, preferably microporous support which is filled from its exterior to its interior surface with a solid, non-removable organophilic polymer which exhibits permselective properties. A support so filled with the polymer and at least 20µm thick, prefer-ably 50µm to about 200µm thick, referred to as a "thick" film, will preferentially block out water in which a target component is dispersed, yet allow diffusion of the target component. The polymer is forced through the pores of the support, which pores, before they are filled, provide open fluid communication between the opposed interior and ex-terior surfaces of the support.  Preferably, impregnated polymer exudes through and overflows the pores, spreading upon the opposed surfaces of the porous support, and provid-ing opposed coextensive films on either side of the porous support, the films being interconnected by microtendrils of polymer in the pores and channels of the support. A module having microporous hollow fiber membranes is impregnated after the module is constructed. The fibers are through-impregnated with a solution of the polymer and the excess swept away with a sweep gas. In a process for separating plural target components from an aqueous stream, the pervaporation module with "thick film" pervaporation membranes, will provide a separation factor at least double that of a conventional module with "thin film" membranes coated upon a microporous support and not filling its pores.

Patent CA-2060649-A1 (CA)
IPC: A23K3/00
Filed: 1990-06-25
Abstract: An economical, yet effective technique for fumigating grain and other particulate foodstuffs involves the continuous controlled passage through the grain or the like of a carrier gas containing phosphine. The concentration of the phosphine in the carrier gas is within the range of from 4 to 200 micrograms of phosphine per litre. The flow of the gas is at a constant linear velocity within the grain, and the gas leaves the grain mass at a velocity of from 0.5 x 10-4 to about 2 x 10-4 metres per second. This fumigation technique is applicable to the fumigation of grain in a storage facility having a plurality of grain silos (13) and a single source (10) of a gaseous fumigant. The single source of gaseous fumigant is connected, via a gas supply duct (11), to gas inlet ports of the silos. The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop across the plate into the silo is substantially greater than the pressure drop across any other component between the gas source and the silo.
Patent CA-2061910-A1 (CA)
Inventor: IPPONMATSU MASAMICHI
IPC: G01F1/704
Filed: 1992-02-26
Abstract: The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 µm are used as the tracer.  Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles.  Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.

Abstract: ABSTRACT OF THE DISCLOSURE      A process of producing a composite semipermeable membrane with high performance, which does not involve a highly ignitable solvent or  a chlorofluorocarbon solvent which destructs the environment is disclosed.  In the process of the present invention, a polyfunctional amine solution and a polyfunctional acid halide solution in a hydrocarbon-based solvent with a flash point of not lower than 10°C are applied on a surface of a microporous substrate to allow interfacial polycondensation reaction so as to form a cross-linked polyamide-based ultra-thin membrane superposed on the microporous substrate.  Then a gas is blown on the surface of the ultra-thin membrane so as to evaporate the hydrocarbon-based solvent, which gas has a velocity at the surface of 2 - 20 m/sec., a temperature of 10 - 80°C that is lower than the flash point of the hydrocarbon-based solvent, and an absolute humidity of not less than 1 g of water per 1 kg of dry gas.

Title: Defibrillateur auriculaire, systemes de fils et methode
Inventor: ADAMS JOHN M
IPC: A61N1/05
Filed: 1992-04-07
Abstract: Un défibrillateur auriculaire implantable fournit une impulsion d'énergie électrique de défibrillation aux oreillettes du coeur en synchronisation avec des ondes R détectées, en réponse à la détection non coïncidente d'une onde R dans une première et une seconde région du coeur. L'impulsion de défibrillation est produite après qu'un nombre prédéterminé d'ondes R consécutives aient été détectées de manière non-coïncidente afin d'assurer une synchronisation fiable. Le défibrillateur auriculaire peut aussi fonctionner en mode de marquage, où un certain nombre d'impulsions de marquage de synchronisation sont appliquées au coeur pour être détectées sur un électrocardiogramme externe. Le détecteur de fibrillation auriculaire du défibrillateur est généralement inactivé, et n'est activé que lorsque l'activité ventriculaire détectée indique une probabilité de fibrillation auriculaire, ce qui permet de conserver une source d'énergie épuisable. Une multiplicité de systèmes de dérivation sont aussi décrits, lesquels peuvent être utilisés avec le défibrillateur auriculaire et réduisent la quantité d'énergie électrique requise pour défibriller le coeur et permettent d'assurer que l'énergie électrique de défibrillation auriculaire appliquée est sensiblement restreinte aux oreillettes du coeur.

Filed: 1993-02-04
Abstract: A cannula is provided for laparoscopic surgery wherein the cannula comprises a housing and elongated tube with a passageway formed within the housing so that laparoscopic instruments may be passed through the housing and the elongated hollow tube into the abdominal cavity of a patient. A pair of rollers are mounted within the housing, the rollers being spring-urged together to close the passageway through the housing when an instrument is withdrawn. A slidable plate having apertures of different sizes are mounted in the housing with the apertures provided with slitted seals therein to close the passageway through the housing. The varying sized apertures in the slidable plate permit laparoscopic instruments of varying diameters to be used and to maintain an effective seal around the instrument. In another embodiment of the cannula a valve is provided which is closed when the rollers within the housing are in engagement with each other. When a laparoscopic instrument is passed through the housing to separate the rollers, the valve moves to an opened position to permit the laparoscopic instrument to pass therethrough.
