Patent CA-2256618-C (CA)
Inventor: BHAT RAJARAM
IPC: H01S5/00
Filed: 1997-05-05
Granted: 2001-08-07
Abstract: Cette invention se rapporte à un circuit intégré opto-électronique à base d'InP, qui contient une couche active ayant un ou plusieurs puits quantiques (36, 38). Selon cette invention, une couche barrière (34) de AlGaInAs est formée, de préférence entre les puits quantiques et le substrat (30) pour empêcher la migration des espèces à partir du substrat et à partir des couches InP inférieures qui tendent à déplacer les longueurs d'ondes d'émission des puits quantiques vers des longueurs d'ondes plus courtes, ce phénomère étant appelé blue-shift. La couche barrière peut être structurée pour que certaines zones des puits quantiques développent un phénomène de blue-shift vers une longueur d'onde plus courte, pendant que d'autres zones conservent leur longueur d'onde plus longue pendant le recuit.

Patent CA-2262689-C (CA)
Inventor: MICHAELS GREGORY A
IPC: G01N29/024
Filed: 1998-06-05
Granted: 2003-04-08
Abstract: An acoustic oxygen sensor can be used in the output lines leading from the sieve beds. This sensor can communicate with a microprocessor to control the production and evacuation cycles of the sieve beds, i.e., for example to determine the period for which a bed is supplied with compressed air and communicates with the reservoir and to determine the pressure of the compressed air and to determine the amount of time that the product gas is fed through the flow equalization path to supply an aliquot of purging gas to a used bed. In the feedback loop, the microprocessor utilizes the measured oxygen concentration and flow rate to optimize the settings necessary to achieve maximum oxygen concentration and flow rate efficiency. Since the microprocessor has the ability to make incremental changes and compare relative values, the optimum values can be determined empirically eliminating the need to perform complex theoretical calculations.

Abstract: A first surface of a basepan of molded plastic for an electric load center includes a plurality of integrally formed fasteners for securing electrical components such as bus bars, neutral bars, and neutral tie bars to the basepan. Each fastener is formed in the absence of any core through the basepan from a second surface obverse to the first. Each integrally formed fastener has a support portion which projects away from the basepan first surface and a flexural portion supported by the support portion. The flexural portion has a first outwardly facing surface inclined with respect to the basepan first surface at an angle that facilitates elastic deformation of the flexural portion, but not the support portion upon application of a bar to the basepan. The flexural portion also has a second inwardly facing surface arranged at an angle with respect to the basepan first surface that facilitates fixed retention of the bar despite any reasonable variation in the thickness of the bar.

Abstract: L'invention concerne des additifs de compositions émollientes au toucher sec comprenant des esters à base d'huile de jojoba et s'utilisant dans les produits de soins personnels, les produits cosmétiques, ainsi que dans les produits cosméceutiques et pharmaceutiques. La composition est essentiellement solide à température ambiante, peut prendre plusieurs formes et dimensions (elle peut notamment être sous forme de particules telles que des sphères) et peut être produite à partir de combinaisons d'alcools gras, d'esters d'isopropyle et d'esters de cire provenant de l'huile contenue dans la graine de jojoba (Simmondsia chinensis), l'huile de jojoba. Ces nouvelles compositions permettent également d'augmenter la gamme d'applications de compositions cosmétiques grâce à un émollient plus polaire et hydrophile que l'huile de jojoba (connue également dans le milieu sous le nom d'esters de cire de jojoba). On peut obtenir les compositions comprenant des alcools gras, des esters d'isopropyle et des esters de cire de jojoba (huile de jojoba) grâce à un nouveau procédé de réaction d'alcoolyse à catalyse basique entre l'huile de jojoba et un alcool, tel que l'alcool isopropylique. Ces esters, pouvant être soit exclusivement des esters de jojoba ou être combinés à d'autres composants d'excipient et de véhicule (y compris d'autres émollients ou liants) peuvent constituer d'excellents compositions d'excipient et de véhicule ou d'administration s'utilisant dans le domaine cosmétique, des soins personnels et/ou dans le domaine pharmaceutique, y compris dans le domaine cosméceutique où les compositions cosmétiques possèdent aussi des propriétés pharmaceutiques ou thérapeutiques. Des matières types avec lesquelles on peut mélanger les esters de jojoba selon la présente invention comprennent, de manière non exhaustive, des huiles et cires cosmétiques, naturelles et synthétiques, y compris des huiles hydrogénées ou partiellement hydrogénées, des huiles de silicone, des huiles minérales, des esters à longue chaîne, des vitamines (notamment la vitamine E), des acides gras à longue chaîne, des alcools, des produits cosméceutiques, des pigments, des extraits botaniques, des esters et éthers, des dimères, des trimères, des oligomères, des polymères et analogues. Ces compositions mélangées peuvent bien entendu être combinées avec les ingrédients actifs devant être administrés par les compositions de la présente invention. Les proportions d'esters de jojoba doivent être sélectionnées de manière à procurer à la composition le toucher sec fortement souhaité. Pour obtenir cela, il faut normalement au moins 10 %, souvent au moins 20 %, de préférence au moins 30 %, idéalement au moins 40 ou 50 % en poids, et encore plus idéalement au moins 60, au moins 70, au moins 80 et au moins 90 % (jusqu'à 100 % en poids) en poids d'une matière d'excipient (solvants et matières actives non compris) dans la composition.
