Patent CA-2351789-A1 (CA)
Title: Isomerization of a pentol
Inventor: GRUENDLER HANSJOERG
IPC: C07C33/048
Filed: 2001-06-26
Abstract: In a process for catalytically isomerizing Z-3-methylpent-2-en-4-yn-1-of to E-methylpent-2-en-4-yn-1-ol in a mixture of both these stereoisomers there are employed as the isomerization catalyst bromine radicals and the isomerization is conducted in a two-phase system of an aqueous phase and the stereoisomeric mixture phase, the stereoisomeric mixture optionally being present in an essentially water-immiscible organic solvent, with intermixing of the reaction mixture and at temperatures from about -10ÀC to about 100ÀC. The source of the bromine radicals is generally an alkali metal or alkaline earth metal bromide, or ammonium bromide. In one embodiment of the process of the present invention a salt of a heavy metal is used as the catalyst for promoting the generation of bromine radicals from the source thereof, and in addition oxygen is generally used as an auxiliary agent for promoting the bromine radical generation. In a further embodiment there is used as such catalyst a strong peroxide-type oxidizing agent, e.g. an alkali metal or alkaline earth metal peroxomonosulphate, peroxoborate, peroxodisulphate or peroxodiphosphate, or the system hydrogen peroxide/alkali metal or alkaline earth metal sulphate. The stereoisomer produced and isolated in the larger proportion, i.e. Z-pentol, is a useful intermediate, e.g. for the manufacture of vitamin A, and the stereoisomer produced and isolated in the smaller proportion, i.e. E-pentol, is also a useful intermediate, in this case e.g. for the manufacture of astaxanthin, zeaxanthin and further carotenoids.

Title: Systeme graphique comprenant un tampon d'echantillonnage super-echantillonne generant des pixels de sortie au moyen de l'ajustement selectif du filtrage pour produire moins d'artefacts
Inventor: DEERING MICHAEL F
IPC: G06T15/00

Abstract: On décrit un système infographique qui utilise un tampon d'échantillonnage super-échantillonné et une unité de calcul programmable échantillon-pixel qui régénère l'affichage, ledit système graphique pouvant ajuster le filtrage pour réduire les artéfacts ou pour réaliser des effets d'affichage. Dans une forme de réalisation, le système graphique peut comprendre un processeur graphique, un tampon d'échantillonnage super-échantillonné et une unité de calcul échantillon-pixel. Le processeur graphique produit une pluralité d'échantillons et les stocke dans un tampon d'échantillonnage. L'unité de calcul échantillon-pixel lit les échantillons dans le tampon d'échantillonnage super-échantillonné et filtre ou convolutionne les échantillons sous forme de pixels de sortie respectifs qui sont ensuite utilisés pour rafraîchir l'affichage. L'unité de calcul échantillon-pixel peut sélectivement ajuster le filtrage des échantillons stockés pour réduire les artéfacts, elle peut par exemple être utilisée pour ajuster sélectivement le filtrage des échantillons stockés dans des séquences voisines pour réduire les artéfacts entre les séquences voisines. L'ajustement du filtre peut être effectué lorsque l'unité de calcul échantillon-pixel génère des pixels de sortie à la même vitesse que le processeur graphique envoyant des échantillons au tampon d'échantillonnage, ou à une vitesse différente (supérieure par exemple) à la vitesse de rendu. L'unité de calcul échantillon-pixel peut être utilisée pour ajuster le filtrage des échantillons stockés en vue de réaliser un effet d'affichage, tel qu'un effet panoramique, un effet de zoumage, la rotation ou des effets de scènes animées entre autres. L'unité de calcul échantillon-pixel peut également ajuster de manière sélective le filtrage des échantillons stockés sur une limite de parties de pixels.

Patent CA-2367629-A1 (CA)
Title: Synchronous signal generator
Inventor: OITA TAKEO
IPC: H03K3/02
Filed: 2002-01-15
Abstract: A synchronous signal generator according to the present invention outputs a pulse with low jitter by setting the sine wave output of a crystal oscillator close to an ideal sine wave, and converting it into a pulse signal. By passing the sine wave output from the crystal oscillator of an oscillation frequency f through a filter unit having an equal center frequency f0, inputting output of a filter unit into a pulse converter, and converting the result into a pulse of a rectangular waveform, thereby obtaining an output signal. By configuring the filter unit by the crystal filter and setting it equal to the crystal oscillator in frequency-temperature characteristic, an output signal can be obtained with low jitter although the temperature changes.
Patent CA-2368209-A1 (CA)
Inventor: MORRIS WILLIAM F
IPC: H01M10/42
Filed: 2000-03-15
Abstract: A metal-air fuel cell battery (FCB) system having an electrolyte, and a movable anode having anode material deposited on two sides of an electrically conductive substrate, which can be either a rotating anode disk, or a linearly-movable anode, sandwiched between two air electrodes, wherein the air electrodes each have at least one recharging portion and at least one discharging portion. The recharging portion of the air electrode is designed for optimum recharging and the discharging portion of the air electrode is designed for optimum discharging such that the fuel cell battery performs to its maximum ability. The recharging air electrode area can be larger than the discharging air electrode area for faster recharge times. The recharging air electrode can be operated at lower current densities to prevent anode densification, anode shape change and dendrite growth. Discharging the anode material on both sides of the anode increases the depth of the discharge and increases the battery's capacity. The anode movement assures the anode is intermittently discharged to reduce passivation and further increases the depth of discharge. The motion of the anode helps to insure uniform replating during recharging. Futher, the movement of the anode stirs the electrolyte assuring a uniform distribution of metal ions. As a result, the invention provides a metal-air FCB system having high energy density, high power density and good rechargeability characteristics.

Patent CA-2384536-A1 (CA)
Inventor: SMITS CHRISSIE MELINDA
IPC: A61F13/26
Filed: 2000-09-12
Abstract: The invention provides a tampon insertion device comprising a tampon applicator having a first end and a second end and a covering that is removably attached to the tampon applicator. The covering covers the tampon applicator at its first end prior to use of the tampon applicator. The covering has at least a pair of compression areas that are oppositely oppose d to one another and also a pair of covering areas that are oppositely opposed  to one another. The compression areas, where no material exists, allow the covering areas to flex toward one another to either touch together or nearly  touch together. This flexing is important because the covering, once removed , is then used as a plunger to expel a tampon residing within the tampon applicator from the tampon applicator. In practice, the covering is removed from the tampon applicator and inserted through the second end of the tampon  applicator for expulsion of a tampon during use of the tampon applicator.</S DOAB>
