Dans ces cuves de désaération généralement grandes est amenée, sous forme d'un mélange dilué, une suspension fibreuse devant être introduite dans une machine à papier. On sait, par les techniques antérieures, que la consistance finale de la pâte de papier devant être amenée de la caisse de tête à la section de toile est de préférence finement épurée juste avant la caisse de tête ou dans le raccordement avec cette dernière. Cette fine épuration nécessite de l'eau neuve désaérée ou équivalent (un second milieu). La caractéristique de cette cuve de désaération est que le même espace gazeux (17) de ladite cuve (2) dans lequel est traité le premier milieu est pourvu d'une seconde paroi de séparation (13) formant un second barrage K2 et que l'enveloppe de ladite cuve est pourvue d'orifices ou d'un orifice d'admission (11) permettant l'introduction du second milieu dans la cuve, et d'un orifice d'évacuation (14) permettant le passage d'un second milieu sensiblement exempt de gaz. L'espace gazeux commun (17) est également pourvu d'un orifice d'évacuation (7) connu en soi, prévu pour le passage du gaz provenant à la fois du premier et du second milieu, et d'un orifice d'évacuation (8, 15) prévu pour l'écoulement de surface/fraction (19) du second milieu séparé par le barrage K2.

Granted: 2005-01-25
Abstract: A process for application of a protective coating to a steel, concrete, or wooden structure so as to provide protection against corrosion, weathering, or other environmental damage in which the surface to be protected is heated to a temperature in a range of about 75°F to about 150°F after which a liquid thermoset primer is applied to the heated material in two stages. The first portion is solidified by heating and then coated with a second portion, forming an uncured liquid thermoset outer primer layer. A melted polymer powder layer is then applied by flamespraying over the uncured liquid thermoset primer layer, forming an intermediate polymer powder layer embedded in the uncured liquid thermoset primer layer. The intermediate melted polymer powder layer is then heated to a flow temperature of the polymer powder and a second layer of melted polymer powder is applied over the intermediate polymer powder layer, forming an outer melted polymer powder layer which then cools to form the final protective coating.

Filed: 1998-02-13
Granted: 2007-05-29
Abstract: A process for the fabrication of indirect dental restoratives includes the making of a first, pre-operative impression of a tooth to be restored using a first polyvinyl silicone (PVS) material disposed in a clear tray, followed by the preparation of the tooth. A second, final post-operative impression of the tooth is taken utilizing a second PVS material. A tooth model is then made by pouring a low viscosity and suitably rigid, third PVS  material into the final impression. Prior to the complete setting of the low viscosity PVS material, a higher viscosity, fourth PVS material is applied onto the model PVS material to form a completed model with base. The model is then fitted into the pre-operative impression matrix made from the first PVS  material. Layers of composite are packed onto the impression in the clear matrix. The model (with attached base) is then inserted into the composite disposed in the first PVS material and the resulting matrix is placed in a single apparatus for conducting both light and heat cure of the dental composite.  The apparatus employs a thermister disposed in a composite material, the thermister/composite assembly being disposed in the curing chamber and connected to a control device which controls a heat lamp also disposed in the apparatus. Curing of the dental composite is performed by heating until the thermister reaches a selected temperature.

Abstract: Conventional distortion compensation circuits have addressed the problem that their distortion compensation amount is greatly reduced at levels other than the designed power level. The present invention provides a distortion compensation circuit that comprises: a vector adjuster; a linearizer; a linear signal extraction path for extracting part of an input signal from the input side of the vector adjuster; a nonlinear signal extraction path for extracting part of an output signal from the output side of the amplifier; a level detector for detecting a combined power level of the signals from the linear signal extraction path and the nonlinear signal extraction path; and a control circuit for adjusting a bias of the linearizer in accordance with the detected combined power level, electrically adjusting the linearizer so that the power detected by the level detector is minimized, and adjusting the vector adjuster so that the power detected by the level detector is minimized every time the linearizer is adjusted. As a result, the distortion compensation circuit of the present invention can optimize distortion compensation at all times independently of the average power changes of the input signal, the secular changes of the amplifier and the state changes of the amplifier caused by temperature changes.

Granted: 2009-04-14
Abstract: A surgical stent (10) is provided which can be radially expanded away from a central axis (2) within a body lumen, such as an artery.  The stent (10) is formed form a series of struts (20) circumscribing a cylindrical contour of the stent (10). Each strut (20) has a series of bends (30) formed therein with each bend including at least one trough (32) and at least one crest (36). Gaps (40) are provided between adjacent struts (20). Each gap (40) is spanned by an axial element such as a tie bar (50) or links (180). Each tie bar (50) attaches to adjacent struts (20) through troughs (32) so that when the stent (10) is radially expanded, the struts (20) are not drawn together, but rather maintain their position and the stent (10) hence maintains its axial length without contracting. Other elements such as the links (180) can be provided spanning the gaps (140) to provide enhanced flexibility for the surgical stent (110) including such links (180).

Abstract: Transcriptional activators which differ in their activation potential by more than 3 orders of magnitude are provided. The transactivators are fusions between a DNA binding protein (e.g., a Tet repressor) and minimal transcriptional activation domains derived from Herpes simplex virus protein 16 (VP16). Substitution mutations at amino acid position 442 within the minimal VP16 domain provide transactivators with differing transactivation ability. Moreover, chimeric activation domains comprising both wild type and mutant minimal VP16 domains provide additional variants with differing transactivation ability. Various aspects of the invention pertain to nucleic acid molecules, vectors, host cells, fusion proteins, transgenic and homologous recombinant organisms and methods of regulating gene transcription.
