Title: Variable angle corner tool
Inventor: WASHBURN FRED
IPC: E04F21/00
Filed: 2005-01-27
Abstract: An adjustable corner tool is provided having outwardly biased blades. The back surfaces of the blades are connected to an angle control assembly that includes fixed-length arms pivotally connected between each of the blades and a central mounting block. Springs rotationally bias the arms away from each other such that the arms push against the back surfaces of the blades to urge the blades apart. In use, resistive force applied against the front surfaces of the blades moves the blades together. Thus, the adjustable corner tool dynamically adjusts to variations in wall corner angles. The adjustable corner toot can be used with corners in the range of about 160 degrees to 40 degrees and the angle of the tool can also optionally be fixed or maximally limited.  In addition, the adjustable corner tool may be adapted to also function as an injection head for delivering spreadable material to a corner.

Title: Correction of amplitude and phase imbalance in psk receivers
Inventor: DICK STEPHEN G
IPC: H04L27/22
Filed: 1999-12-07
Abstract: The present invention balances the amplitude and phase of a received QPSK signal that may have been corrupted during transmission. The system determines the amplitude of the I and Q symbols of a received signal, compares them, and applies a correction to one or both channels to correct for amplitude imbalance. For phase imbalance, the system calculates the cross-correlation of the I and Q symbols which should average to zero. A correction factor is derived from the cross- correlation and applied to both channels, returning the phase cross-correlation to zero. The output from the system is a signal corrected in both amplitude and phase.

Abstract: An integral, one-piece silanated particle impregnated gutta percha core/cone technique employs a thin layer of a luting agent, such as glass ionomer cement with a machined gutta percha core/cone, precisely matches the preparation, thereby reducing leakage and achieving a hermetic seal. The hermetic seal is further enhanced by a mono-block bond that occurs between the silanated particles in the gutta percha and the appropriate chemical sealant. Optional cryogenic treatment of the gutta percha material changes its molecular weight, making it stiffer and conducive to forming an integral, one piece core/cone, without the need for a separate carrier core to install the tapered gutta percha core/cone within the root canal. Additionally, the tapered body of the core/cone may be reticulated in a slightly three dimensional texturized framework to increase surface area and therefore increase retention. Optional line demarcation indicia are also placed on the core/cone. Additionally, the head of the core/cone can be gripped by a delivery vehicle clasp.

Abstract: L'invention concerne un système de protection incendie à gaz inerte à pression relativement faible (20) protégeant une pièce (22) ou autre contre les effets de l'incendie ou autres. Le système (20) comprend plusieurs cylindres de gaz inerte sous pression (24) équipés d'une unité de valve (26); chaque unité (26)étant couplée via un conduit (28) à une rampe de distribution (30). Les unités en question (26) assurent la distribution de gaz depuis les cylindres (24) à une pression généralement constante (habituellement à environ 10 - 100 bars) sur une partie sensible de la durée de la distribution, ce qui procure une protection efficace sans matériel onéreux de manipulation/distribution de gaz haute pression et une réduction de la zone de ventilation dans la pièce grâce à une surpressurisation inférieure dans la pièce. Chaque unité de valve (26) comporte un corps de valve (48) et un élément d'étanchéité de type à piston susceptible d'être déplacé (56). La pression de gaz fournie par le cylindre (24) et un ensemble ressort (184) contraignent l'élément (56) en position de valve ouverte, et cet effet est contrebalancé par la pression de gaz dans des chambres d'égalisation et de modulation (180,182) à l'intérieur de l'unité de valve (26). En cas de détection de risque, les unités de valve (26) sont actionnées par évacuation du gaz hors des chambres (182), ce qui assure le flux de gaz depuis les cylindres (24). En cours de flux, le gaz entre dans les chambres (182) et en sort pour fournir la pression de gaz généralement constante souhaitée. En fin de flux, l'ensemble ressort (184) a une action qui prédomine et maintient l'unité de valve (26) ouverte jusqu'à la fin du flux

Abstract: L'invention concerne des procédés de cimentation de formations souterraines, des compositions de ciment et des procédés de production desdites compositions. Un coulis de ciment est introduit dans une formation souterraine et un agent de gonflement est introduit dans cette formation souterraine de façon à réduire une quantité d'eau s'écoulant dans le coulis de ciment. Cet agent de gonflement peut être combiné à un fluide porteur avant d'être introduit dans la formation souterraine. De façon alternative, cet agent de gonflement peut être prémélangé au coulis de ciment de façon à former une nouvelle composition de ciment, laquelle composition de ciment est ensuite introduite dans la formation souterraine. Cet agent de gonflement est présent en quantité efficace de sorte qu'après avoir absorbé l'eau et gonflé pour former une masse gélatineuse, cet agent bloque sensiblement la voie d'écoulement de l'eau dans la composition de ciment ou réduit des pertes occasionnées par de faibles intervalles de pression de pores, ce qui permet d'éviter que l'intégrité de la composition de ciment ne soit compromise ou perdue à cause de pores, fractures, fissures, etc.

Title: Method for stabilization of enzymes during exposure to sterilizing radiation
Inventor: JEZEK JAN
IPC: C12N9/96
Filed: 2004-06-04
Abstract: The present invention provides a composition comprising an enzyme, e.g.  oxidase enzyme, a source of zinc and/or ammonium ions and a source of lactate ions. The compositions are typically sterilised by exposing the compositions to sterilising radiation, e.g. gamma radiation. The incorporation of a source of zinc and/or ammonium ions and a source of lactate ions, e.g. zinc L-lactate, in the enzyme-containing composition results in an improvement in enzyme activity post-sterilisation. The presence of a source of zinc and/or ammonium ions and a source of lactate ions in the composition therefore has a protective effect on the enzyme during exposure to sterilising radiation so that good recovery of enzyme activity can be obtained.
