Patent CA-2183153-A1 (CA)
Inventor: CROUSE JERE W
IPC: D21F3/02
Filed: 1994-12-20
Abstract: Presse à contact entre les rouleaux étendu qui comporte un contre-rouleau (22) chauffé sur la surface duquel une bande de papier (28) est préchauffée avant de passer entre les rouleaux à contact linéaire étendu. La bande de papier est retenue sur la surface du contre-rouleau (22) pour permettre le séchage après pressage. Pendant une partie du séchage après pressage, la presse à contact entre les rouleaux étendu peut être configurée de manière à ce que la bande de papier ne soit pas soutenue par le feutre de pressage/séchage, ce qui permet la libre aération de la bande. Dans certains cas, il est possible d'ajouter dans cette zone une unité auxiliaire d'aspiration destinée à évacuer la vapeur. Cette presse à haute température est capable de produire une siccité de sortie de l'ordre de soixante-cinq pour cent, contre cinquante pour cent pour la technologie classique. On peut s'attendre à ce que cette combinaison de pressage et de séchage à haute température améliore la résistance maximale de la bande d'environ 20 pour cent ou plus par rapport aux procédés de pressage classiques. Deux séchoirs de presse à haute température de la présente invention peuvent être combinés pour obtenir une siccité de sortie de soixante-dix pour cent environ.

Abstract: Cette résine époxy polyvalente possédant de bonnes propriétés à hautes températures, permettant une utilisation prolongée à des températures supérieures à 120 ~C, est dérivée d'un précurseur de la formule (I), dans laquelle R?3¿ à R?8¿ inclus sont indépendamment choisis parmi hydrogène, alcoyle C¿1?-C¿3? ou halo-alcoyle, et R?9¿ représente hydrogène, alcoyle ou halogène, n valant 0, 1 ou 2. Ce précurseur (I) peut être ponté de façon autonome ou ponté en croix avec des précurseurs d'autres composés époxy du type TGDDM. De tels pontages en croix donnent naissance à un mélange complexe ne contenant pas seulement le produit mélangé mais également les produits à pontage autonome de chaque constituant. Nonobstant le processus de fabrication chimique précise du mélange, la température de transition vitreuse observée de celui-ci est supérieure à celle des résines TGDDM obtenues sans précurseur (I). Si le substituant en position R?9¿ représente alcoyle ou halogène, la formation d'oligomères est supprimée et le mélange obtenu est moins complexe.
Patent CA-2185259-A1 (CA)
Inventor: ROTHENBURG LEONARD
IPC: B09B1/00
Filed: 1996-09-11
Abstract: The invention is an apparatus and method for injection of wastes in slurry form within an underground formation. The method consists of: identifying a suitable target stratum; calculating the approximate total available storage volume of the target strata; injecting a slurry of waste materials into a well in a series of injection episodes separated by interinjection periods; measuring the well bottom pressure of the slurried wastes during each injection episode and interinjection period; and terminating the injection process when the target strata is saturated with slurried wastes. An injection episode is terminated when the well bottom pressure begins to climb substantially above the steady state level, and an interinjection period is terminated when the well-bottom pressure drops below a fixed level. Surface uplift indicators, microseismic measuring and well-bottom pressure within monitoring wells may be used to assess the distribution and movement of embedded solids both during and after the injection process. The apparatus comprises means to produce and inject an appropriate slurry and monitor the entombed slurry during and after the injection process.

Title: Seed priming
Inventor: MCKEE JOHN MICHAEL TERENCE
IPC: A01C1/06
Filed: 1995-09-15
Abstract: A method for treating plant seed is provided comprising contacting them with a first surface of semi-permeable membrane (2) having first and second surfaces, the second surface being in direct contact with a solution of predetermined osmotic potential (5), whereby the seeds (6) abstract water from the solution through the membrane (2), wherein the seed (6) and semi-permeable membrane (2) are constantly or periodically caused to move relative to each other such as to constantly or periodically reorient the seed (6) with respect to the first surface such that the transfer of water occurs evenly over substantially the entire surface area of the seed. For seed priming the osmotic pressure and the period for which the seeds (6) are maintained in contact with the membrane (2) are sufficient to allow pre-germinative metabolic processes to take place within the seeds up to a level limited to that immediately preceding radicle emergence. Methods for germinating seed and inducing desiccation tolerance in seed are also provided. Preferably the semi-permeable membrane (2) is provided in the form of a tube of circular or polygonal cross section which is rotated with the seeds (6) on its inner surface and the solution retained between its outer surface and a further body to which the membrane is sealed in a watertight manner.

Inventor: JURANKA PETER
IPC: A01N43/30
Filed: 1997-02-27
Abstract: The method of this invention entails the use of dillapiol or its analogues and derivatives to affect cells expressing multidrug resistance (MDR) activity. In one aspect, dillapiol or its analogues and derivatives are used alone as agents that exert a direct toxic effect on cells presenting an MDR phenotype. In another aspect, dillapiol or its analogues and derivatives are used as chemosensitizers to chemical agents, such as chemotherapeutic agents, insecticides, and nicotine, in order to increase the efficacy of these agents. This method is useful for treating pathologies and physiologies in which MDR plays a role, such as certain cancers and diseases (eg. malaria), different states of tolerance or resistance (eg to insecticides), and addiction (eg. to nicotine and opiates).

Patent CA-2229509-A1 (CA)
Title: Chemical signal-impermeable mask
Inventor: TIERNEY MICHAEL
IPC: G01N27/30
Filed: 1996-07-16
Abstract: A chemical signal-impermeable mask (1) is positioned in the electrolyte flow such that the mask is between a source of chemical signal and a working electrode (4) which senses the chemical signal transported from the source (e.g., by diffusion). The configuration of the mask is such that the mask prevents substantially all chemical signal transport from the chemical signal source/having a radial vector component relative to a plane of the mask/and the catalytic face of the working electrode, thus allowing primarily only chemical signal transport that is substantially perpendicular to the place of the mask and the catalytic surface (6) of the working electrode. By reducing or eliminating chemical signal radial transport toward the working electrode, the mask thus significantly reduces or eliminates edge effects. By substantially reducing edge effects created by radial transport of chemical signal, it is possible to obtain a more accurate measurement of the amount (e.g., concentration) of chemical signal that is transported from a given area of source material.
