Patent CA-2280666-C (CA)
Inventor: HALL JACOB H
IPC: F23N3/04
Filed: 1999-08-23
Granted: 2003-10-21
Abstract: A fuel-fired water heater has a combustion chamber disposed above a wall structure forming a flow path for combustion air being drawn into the combustion chamber during firing of the fuel burner portion of the water heater. A combustion air shutoff system is incorporated in the water heater and functions to sense an undesirably high firing temperature in the combustion chamber and responsively shut off essentially all further air flow to the combustion chamber and thereby terminate combustion therein. In various disclosed embodiments thereof, the combustion air shutoff system includes a damper member movable between an open position in which its permits air flow through the combustion air flow path, and a closed position which it blocks essentially further air flow through the combustion airflow path. The damper is releasably held in its open position by a eutectic metal fusible link member positioned exteriorly adjacent an exterior wall of the combustion chamber. When a predetermined high limit firing temperature is reached within the combustion chamber, the correspondingly increased temperature of the combustion chamber wall melts the fusible link member. In response, the shutoff system causes the damper to move to its closed position to terminate essentially all further flow of combustion air through the combustion air flow path into the combustion chamber.

Title: Nucleic acid sequences that can be used as primers and probes in the amplification and detection of all subtypes of hiv-1
Inventor: JURRIAANS SUZANNE
IPC: C12N15/09
Filed: 1998-08-05
Granted: 2009-07-07
Abstract: The present invention is related to nucleic acid sequences that can be used in the field of virus diagnostics, more specifically the diagnosis of infections with the AIDS causing Human Immuno-deficiency Virus (HIV). With the present invention nucleotide sequences are provided that can be used as primers and probes in the amplification and detection of HIV-1 nucleic acid. The oligonucleotide sequences provided with the present invention are located in the LTR part of the HIV  viral genome. It has been found that, by using the sequences of the present invention in methods for the amplification and detection of nucleic acid a sensitive and specific detection of HIV-1 can be obtained. The benefit of the sequences of the present invention primarily resides in the fact that, with the aid of primers and probes comprising the sequences according to the invention the nucleic acid of all presently known subtypes of HIV-1 can be detected with high accuracy and sensitivity. So far no primer pairs or hybridization probes have been developed that would allow the detection of such a broad range of HIV-1 variants. The oligonucleotide sequences according to the present invention are especially useful in methods for the amplification of nucleic acid.

Abstract: An enrober (100) for applying a topical coating to an exterior surface of multiple pieces of a food base is disclosed having a marked decrease in the amount of build up upon the internal surface of the drum (102) allowing for reductions in cleaning service requirements and its concomitant losses in production capacity and for reductions in undesirable product agglomerates. In the preferred form, the drum (102) is formed by a thin wall in a generally cylindrical shape and formed of hydrophobic material in the form of high-density polyethylene having low-stick characteristics with the topically coated food base. Moisture, in addition to any present in the topical coating, is added to the drum (102) to prevent or practically eliminate build up on the drum (102). The topical coating in the form of a slurry can be co-sprayed with steam in an atomized intermixed spray onto the food base by a nozzle (10, 80). Also, a renewable barrier between the continuous inner surface of the drum (102) and the food base can be formed by spraying water or steam by nozzles (116) as a thin film of water onto the inner surface of the drum (102) above the food base.

Title: Polyionic coatings in analytic and sensor devices
Inventor: TEXTOR MARCUS
IPC: G01N33/543
Filed: 2000-04-28
Granted: 2009-12-22
Abstract: Multifunctional, polyionic copolymers are synthesized on/or applied to substrate surfaces for analytical and sensing purposes, the coatings being particularly useful for suppression of non-specific interaction, adsorption or attachment. Groups can be coupled to, integrated into or absorbed to the multifunctional polymer that are able to recognize, interact with and bind specifically to target analyte molecules. These materials can also be used to modulate biological interactions upon substrate surfaces for use as selective implant surfaces that resist cell attachment and may optionally promote the attachment of specific cell types or induce a particular cellular behaviour. The multifunctional polymer coatings typically include brush copolymers based on a polycationic or polyanionic backbone with side chains that control interaction with the environment, such as poly(ethylene glycol) or poly(ethylene oxide)-based side chains that decrease cellular adhesion, and analyte-specific side chains.

Abstract: La présente invention concerne une carte à fenêtres destinée à être insérée dans un système d'ablation réfractive au laser, utilisé pour l'ablation au laser de la cornée. Cette carte à fenêtres est conçue pour un usage chirurgical unique, pour des raisons de précautions chirurgicales, et afin d'effectuer les ablations de meilleure qualité, en plus de la reproductibilité. Ladite carte à fenêtres est chargée dans le système d'ablation réfractive au laser, dans une voie située entre le système laser et l'oeil. Ladite carte à fenêtres est positionnée de façon précise par des organes de positionnement et l'action laser d'ablation est inhibée si la carte n'est pas positionnée dans une certaine zone de tolérance. Alternativement, le système laser peut déterminer la position de la carte à fenêtres et régler un profil d'ablation calculé ou régler le système optique, afin de s'adapter à tout mauvais alignement des fenêtres dans la carte à fenêtres. La carte contient une fenêtre à faisceau diffus qui permet de profiler une distribution d'intensité spatiale à profil unique. Le profil présente une partie supérieure sensiblement plate, alors que les côtés du profil sont inclinés jusqu'à ce qu'un seuil d'intensité d'ablation soit atteint, les côtés devenant alors sensiblement verticaux. La carte peut contenir plus d'une fenêtre à faisceau diffus, ainsi qu'une fenêtre à faisceau net qui crée un profil de forme carrée, utilisé pour tester la fluence. Chaque fenêtre à faisceau diffus est formée par une fenêtre centrale et par plusieurs orifices de tailles différentes qui entourent la fenêtre centrale et sont disposés de façon que l'effet de diffraction d'ensemble produit un profil d'intensité spatiale à faisceau diffus, comparé au profil de forme carrée, net.
