Abstract: Catalysts which produce linear low density polyethylene with a bimodal molecular weight distribution, particularly those containing a high molecular weight fraction. The catalysts are formed by contacting a carrier with an organomagnesium compound to incorporate magnesium into the carrier, and subsequently contacting the carrier containing the incorporated magnesium with a silicon compound and subsequently with a transition metal source; the transition metal containing intermediate is again created with an organomagnesium compound to form a catalyst precursor, and the catalyst precursor is activated with dimethylaluminum chloride.

Patent CA-2183502-C (CA)
Title: Gas detector
Inventor: TULIP JOHN
IPC: G01N21/39
Filed: 1996-08-16
Granted: 2008-10-14
Abstract: A gas detector of gas in a target zone has a transmitter of frequency modulated light and a receiver. In the receiver, a homodyne detection circuit mixes a detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. The homodyne detection circuit includes a bandpass filter, amplifier, phase lock loop and phase shifter. Etalon fringes are reduced by moving them to high frequencies and filtering them out. Gas density is measured by comparison of the detected signal from the target zone with a signal from a gas reference cell. A method of detecting gas includes transmitting frequency modulated light through a target zone, receiving the light, and homodyne detection of the detected signal by mixing the detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. Light from a laser transmitter propagates along several optical light guides from a laser transmitter to a laser receiver. The optical light guides form a guided light path traversing each of several target zones where unwanted gas may be present. An optical switch permits selection of one of the paths and hence one of the target zones for the detection of gas. A preferred light guide uses optical fibers with optical switches, or a combination of a splitter and a switch. A lens system provides for the collection of light from a transmitting fiber optic and receiving fiber optic. The gas detector is provided with means to eliminate phase sensitivity of the detector. Also, a gas detector for detecting a target gas in multiple target zones. A light collector receives light from the first scanning optical element that has returned from the multiple target zones and directs the light towards the receiver. A controller controls the position of the first scanning optical element and thereby controls which of the target zones is traversed by light from the laser transmitter.

Abstract: La présente invention, qui concerne un procédé de soudage et un appareil utilisable à cette fin, apporte des améliorations notables concernant les effets indésirables induits par la contrainte résiduelle de traction, particulièrement au niveau de la paroi interne des soudures de chaudronnerie. Le procédé associe un joint de soudure extrêmement fin et une électrode de soudure (10) fine, de forme cylindrique non circulaire et de section oblongue, la longueur de section de l'électrode se présentant, pendant le soudage, en alignement et parallèle par rapport à la longueur du joint de soudure. Cette association permet de faire la jonction d'éléments de chaudronnerie avec d'autres composants sensibles à la contrainte résiduelle, du simple fait que la préparation initiale pour joint de soudure et la soudure achevée (6) sont d'une largeur particulièrement fine pour un rapport apparent profondeur / largeur élevé. L'électrode peut également comporter une lame en alliage au tungstène (18). Cette lame est faite de feuilles d'alliage de tungstène traitées par découpe ou estampage. La forme préférée de la lame est un triangle isocèle. La base de la lame triangulaire plate se fixe dans une fente pratiquée dans une poignée pour électrode (20) caractérisée par une forme de préférence en T, le bord de fixation (20a) de la poignée pour électrode étant raccordé à une torche de soudage de type standard.

Abstract: A procoss and appara- tus for catalytically conventing hydrocarbons to light olefins with a short contact circulat- ing fluidized bed reactor sys- tem. The process comprises the steps of feeding a hydro- carbon feedstock into a reac- tion zone (1) containing a solid catalyst, contacting the hydro- carbon feedstock in the reac- tion zone (1) with the catalyst under conditions which favour catalytic conversion of hydro- carbons into light olefins, sepa- rahng the reaction products ob- tained from the reaction zone (1) after catalytic conversion, recovering the catalyst, and re- generating the deactivated cat- alyst in a regenerator (3). Ac- cording to the invention, the hydrocarbon feedstock is con- tacted with the catalyst in a cir- culating fluidized bed reactor (1) at a residence time in the range of 0.1 to 3 seconds. The process is used for preparing propylene, butylenes and pentenes and high octane, low benzene gasoline frac tion by catalytic conversion of LGO, HGO, VGO or naphta, using conventional or improved FCC catalysts. The process can also be used f or preparing propylene, isobutylene or isoamylene rich products by catalytic dehydrogenation from propane, isobutane or naphta, res pectively, using conventional or improved dehydrogenatio n catalysts for fluidized bed service.
