Patent CA-2423088-A1 (CA)
Title: Pressurized backflush system for a filter
Inventor: MCGOWAN DAVID R
IPC: B01D29/11
Filed: 2002-08-26
Abstract: A filter backflushing system including an accumulator containing a pressurized bladder which propels a supply of backwash fluid contained within the accumulator in a reverse direction through a filter element. While the backwash fluid is pumped within the accumulator, an inert gas inside the bladder is compressed against the inside walls of the accumulator. Upon reaching a pressure of approximately 300-600 psi, the filtered fluid is released from the accumulator and the full energy of the compressed gas is released as well. This release produces a high pressure rapid burst of backwash fluid which effectively removes clogging contaminants from a filter element.

Title: Systeme pouvant proteger des arbres et des structures contre une infestation
Inventor: THOMPSON JAMES
IPC: A01M29/00
Filed: 2001-10-18
Abstract: L'invention concerne un système qui sert à protéger des arbres et des structures contre une infestation d'insectes rampants ou grimpants, par fixation d'une barrière contre les insectes sur la surface de la paroi de l'objet à protéger. La barrière est constituée d'un dispositif en forme de ceinture, qui peut être fabriqué avec un matériau en feuille de plastique enveloppant l'objet à protéger et comprendre un moyen de contact qui vient au contact de la surface de l'objet. Le moyen de contact peut présenter une épaisseur déformable, conférée par exemple par une couche de textile non tissé, pour empêcher le passage d'insectes entre la barrière et la surface de l'objet. Les extrémités libres du dispositif en forme de ceinture sont attachées l'une à l'autre afin de retenir le dispositif contre la surface de l'arbre et placer le moyen de contact contre la surface de l'arbre. Le dispositif en forme de ceinture comporte un moyen à surface glissante, qui présente un coefficient de frottement faible par rapport aux insectes et empêche ceux-ci de se déplacer sur le dispositif en forme de ceinture et donc d'aller au-delà et infester l'arbre ou la structure à protéger. La surface glissante peut être ménagée par application d'un revêtement en polymère fluoré (le polytétrafluoréthylène (PTFE) par exemple) sur le dispositif en forme de ceinture; elle peut autrement être fixée de manière appropriée ou intégrée au dispositif en forme de ceinture.

Patent CA-2440260-A1 (CA)
Inventor: MORGAN CARLTON B
IPC: A61N1/36
Filed: 2002-03-07
Abstract: The following disclosure describes several methods and apparatus for intracranial electrical stimulation to treat or otherwise effectuate a change in neural-functions of a patient. Several embodiments of methods in accordance with the invention are directed toward enhancing or otherwise inducing a lasting change in neural activity to effectuate a particular neural-function.  Such lasting change in neural activity is defined as "neuroplasticity". The methods in accordance with the invention can be used to treat brain damage (e.g., stroke, trauma, etc.), brain disease (e.g., Alzheimer's, Pick's, Parkinson's, etc.), and/or brain disorders (e.g., epilepsy, depression, etc.).  The methods in accordance with the invention can also be used to enhance neural-function of normal, healthy brains (e.g., learning, memory, etc.), or to control sensory functions (e.g., pain). Certain embodiments of methods in accordance with the invention electrically stimulate the brain at a stimulation site where neuroplasticity is occurring. The stimulation site may be different than the region in the brain where neural activity is typically present to perform the particular neural function according to the functional organization of the brain. In one embodiment in which neuroplasticity related to the neural-function occurs in the brain, the maethod can include identifying the location where such neuroplasticity is present. In an alternative embodiment in which neuroplasticity is not occurring in the brain, an alternative aspect is to induce neuroplasticity at a stimulation site where it is expected to occur. Several embodiments of these methods that are expected to produce a lasting effect on the intended neural activity at the stimulation site use electrical pulses that increase the resting membrane potential of neurons at the stimulation site to a subthreshold level.

Filed: 2002-08-09
Abstract: Les procédés connus de fabrication de plaques de placoplâtre de poids spécifique faible possèdent un inconvénient, à savoir que les pores réduisent l'adhérence entre le carton et le plâtre. De nombreux efforts ont été déployés pour améliorer cette adhérence, mais le poids spécifique des plaques ne peut alors être aussi faible que désiré. Le procédé selon la présente invention permet d'obtenir avec des moyens simples une forte adhérence entre le carton et le plâtre, pour un poids spécifique des plaques maintenu aussi faible que possible. A cet effet, après application du plâtre sur une bande de carton et avant la prise du plâtre, au moins une des bandes de carton est soumise, sur sa face opposée au plâtre, à un vide partiel. La présente invention concerne également la fabrication desdites plaques de placoplâtre.
