Filed: 1999-09-20
Abstract: This invention relates to a novel apparatus and method for automatically and dynamically regulating the intake of air into the combustion chamber of a heating unit such as a wood burning stove, furnace, or fireplace to ensure even and efficient burning of fuel. More particularly, this invention pertains to a method and apparatus that uses negative gas pressure in the heating unit's flue, and no additional temperature or pressure sensors, to automatically and dynamically control a damper regulating intake of air into the combustion chamber in inverse relation to changes in negative flue gas pressure. This method and apparatus are especially useful in combination with a heating unit having two combustion chambers, one chamber for combustion of solid fuel and a second chamber for further combustion of exhaust gases and other byproducts from combustion in the first chamber. The two-stage combustion in a dual chamber heating unit is an especially dynamic situation where traditional static controls are not very effective.

Patent CA-2288277-A1 (CA)
Inventor: PADGETT MARY BETH BLAIR
IPC: A61M5/34
Filed: 1998-05-08
Abstract: The present invention provides a safety syringe having a syringe cylinder with a proximal end and a distal end, a piston stem for insertion in the proximal end of the cylinder, a needle cannula capable of being retracted in a proximal direction into said syringe cylinder, and a needle cannula attachment hub capable of attachment to the syringe cylinder. An interior configuration of the hub includes an interference portion in an adhesive area of the hub, the adhesive area filled with adhesive to releasably attach the cannula to the hub. The interference portion has a contact surface and a distal surface with the angle between the contact surface and the hub wall less than the angle between the distal surface and the hub wall so that a greater force applied on the cannula in a distal direction is required to separate the cannula from the hub as compared to the force required to be applied on the cannula in a proximal direction to separate the cannula from the hub. In an alternate embodiment the interior configuration of the hub includes a narrow distal portion which may include a plurality of annular grooves and an enlarged well area disposed proximal thereto. The well area and the annular grooves are filled with an adhesive for releasably attaching the needle cannula to the hub. A plug member formed of a relatively soft resilient material may be received within the piston void between a distal end of the piston stem and the needle capturer. The plug member maintains proper alignment of the capturer and seals-off a portion of the lateral port of the needle cannula and the proximal opening of the needle cannula after it has passed through the capturer.

Title: Plasma treater systems and treatment methods
Inventor: SPENCE PAUL
IPC: C23C16/40
Filed: 1998-07-13
Abstract: Continuous-feed plasma treater systems are designed to treat continuous, such as webs or films, by continuously feeding the substrates through an enclosure having a plasma discharge that alters the substrate's surface properties in some desirable fashion. The plasma discharges are generated by one or more electrode assemblies housed within the enclosure. In general, the plasma treater systems of the present invention have one or more cylinder-sleeve electrode assemblies and/or one or more cylindrical cavity electrode assemblies. A cylinder-sleeve electrode assembly comprises a cylinder electrode and a sleeve electrode positioned with its concave face facing and substantially parallel to the cylinder electrode to form an annular gap between the outer surface of the cylinder electrode and the inner surface of the sleeve electrode. The electrode assembly is adapted to be excited to generate a plasma within the annular gap to form a primary plasma discharge zone for exposure of the plasma to a substrate. A cylindrical cavity electrode assembly comprises (1) a cavity electrode, having a cylindrical bore and a wall slot running parallel to the cylindrical bore and exposing the cylindrical bore; (2) a cylinder electrode coaxially positioned within the cylindrical bore of the cavity electrode to form an annular gap between the outer surface of the cylinder electrode and the surface of the cylindrical bore, the annular gap forming a primary plasma discharge zone; and (3) a treater drum positioned adjacent to the wall slot of the cavity electrode.  During operations, the substrate is translated past the wall slot by the treater drum and exposed to plasma species that are convected from the primary plasma discharge zone to the wall slot. Plasma treater systems of the present invention can be used (a) to treat substrates in an efficient cost-effective manner and (b) to produce treated substrates having superior surface properties as compared to those generated using prior-art systems, such as corona-type discharge systems.

Abstract: L'invention concerne de nouvelles varistances à base d'oxyde de zinc ainsi qu'une méthode de fabrication de celle-ci, dans laquelle on utilise comme produits de départ des poudres nanocristallines obtenues par broyage mécanique intense et on fait subir au mélange obtenu à partir de ces poudres nanocristallines un traitement de consolidation tel qu'un frittage, dans des conditions de température et de temps adéquatement choisies de façon à conserver la plus petite taille possible de grains de ZnO. Les varistances ainsi obtenues ont une microstructure très fine, homogène et une taille moyenne des grains typiquement inférieure ou égale a 3 .mu.m, ce qui est cinq fois plus petit que la taille de grains des matériaux conventionnels. Ces nouvelles varistances ont un plus grand nombre de joints de grain par unité de longueur et donc une tension de claquage beaucoup plus élevée. Cette tension est typiquement supérieure à 10 kV/cm et peut atteindre 17 kV/cm ce qui est presqu'un ordre de grandeur au dessus de la tension de claquage des varistances conventionnelles. Le coefficient de non-linéarité de la courbe de courant-tension est aussi amélioré. Il est supérieur à 20 et peut atteindre des valeurs aussi élevées que 60. En outre, les courants de fuite en dessous de la tension de claquage des varistances ainsi produites, sont plus faibles.
