Granted: 2006-09-19
Abstract: The present invention relates to a method of producing an impregnated wooden product from a wooden article. The article is pressed isostatically with a pressure exceeding 1,000 bars in a first method step. The wooden article is then placed in a bath containing a liquid-impregnating agent in a second method step and allowed to swell so that at least a part of the impregnating agent is absorbed by the article. The method may optionally be supplemented with a third method step in which the article is pressed isostatically with a pressure exceeding 1,000 bars, so as to form a hard element. The third method step may alternatively be applied to a conventionally pressure-impregnated article.

Title: Rudder assembly with a controlled boundary layer control for an aircraft
Inventor: PFENNIG JURGEN
IPC: B64C21/06
Filed: 1997-10-20
Granted: 2005-01-04
Abstract: The boundary layer flow along the surface of an aircraft rudder assembly is controlled by suction applied through perforations primarily installed in the leading edge of the rudder assembly.      The control is such that a laminar flow is enforced or at least such that any turbulent flow is displaced so that it begins downstream of the rudder assembly leading edge. Suction air chambers are arranged along the leading edge inside a nose box of the rudder assembly and these boxes are connected through air ducts and a valve system to an exhaust fan. The valve system and the exhaust fan are controlled by a central processing unit providing a flow controller for the suction in response to control signals produced from rated values and sensed actual valves to provide a uniform distribution of the suction along the leading edge of the rudder assembly. The suction system may be switched over to a de-icing mode by blowing warm air out through the perforations in a controlled manner.

Title: Addition of amine to improve paraformaldehyde
Inventor: SUPPLEE CAROLYN
IPC: C07C43/30
Filed: 1997-03-19
Granted: 2004-10-19
Abstract: Disclosed is a process to produce paraformaldehyde grills having a low dissolution time and low concentration of insoluble formation. The insolubles are believed to lead to stickiness, tackiness, and loss of flowability of the product, loss of handling, and lead to storage problems of the final grill product. To address this problem, a concentrated formaldehyde solution is prepared having a purity ranging from 37 %-99 % and may be mined with an amine additive, an amine and alcohol additive, or amine, alcohol, and caustic additive. Alternatively, the final grill may be sprayed with an amine or amine mixture stabilizer.

Granted: 2006-10-10
Abstract: Parallel spaced grooves are cut within the surface of an existing reinforced concrete member in the direction of bending and at locations where existing tensile reinforcing is inadequate. Elongated reinforcing elements, such as composite rods with continuous carbon fibers, are positioned within the grooves, after a curable bonding material, such as an epoxy resin, is inserted into each groove so that the bonding material surrounds the reinforcing element, The material is formed flush with the surface and allowed to cure to bond each reinforcing element to the concrete defining the corresponding groove. The grooves and reinforcing elements extend within the top surface of a concrete slab across a beam or support for the slab, extend within the bottom surface of the slab at least fifty percent of the distance between adjacent supports for the slab, or within a vertical surface of a concrete or masonry wall or column.
Patent CA-2261303-C (CA)
Inventor: BERKSTRESSER GORDON A IV
IPC: D06P5/13
Filed: 1999-02-05
Granted: 2008-10-07
Abstract: A method for removing color and extracting dyes from ionically dyeable polymeric materials is provided. The method includes contacting the ionically dyeable polymeric material with a swelling agent for the material under conditions sufficient to effect diffusion of the dye from the material. The process is especially useful for removing colors from ionically dyeable polymeric materials as part of a recycling process for such materials. Also, the extracted dye may be recovered for re-use as the swelling agent and contacting composition are substantially non-reactive with the dye.

Title: Digital qam modulator using post filtering carrier recombination
Inventor: ZHANG QIN
IPC: H04L27/36
Filed: 1999-03-01
Granted: 2002-02-19
Abstract: The quadrature amplitude modulator of the present invention allows from 6 to 8 independent compressed channels to occupy a 6 MHz bandwidth while reducing processing power by 33 percent for 8 levels of modulation offered by 64-QAM and by 25 percent for 16 levels of modulation offered by 256-QAM. The QAM modulator is implemented with a reduction in the total number of binary parallel multipliers and the use of LUTs (look-up tables) storing precomputed filter weighting coefficients thereby increasing operational throughput. The reduction in multipliers is achieved by using post filtering carrier combination which similarly reduces the number of MAC (multiply and accumulate) operations performed during filtering. The invention can be implemented as an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).

Granted: 2001-04-10
Abstract: L'invention concerne un procédé d'extraction de propane, de propylène et d'autres constituants hydrocarbures plus lourds contenus dans un flux de gaz d'hydrocarbures. Ce flux est refroidi et/ou détendu de façon à être partiellement condensé, puis est séparé de manière à fournir un ou plusieurs C3 contenant des flux liquides et un premier flux de vapeur. Ces flux sont ensuite amenés à une colonne de distillation où un second flux de vapeur est séparé de façon que soit extrait un produit contenant la majeur partie des constituants C3 et des constituants hydrocarbures plus lourds. Un flux de distillation est extrait de la colonne sous le point d'alimentation du premier flux de vapeur, puis est acheminé vers le second flux de vapeur de façon à produire un échange thermique afin de refroidir le flux de distillation et à en condenser au moins une partie. Un flux condensé est ainsi obtenu. Une partie au moins du flux condensé est acheminée vers la colonne de distillation au niveau d'une position d'alimentation en haut de colonne. Les quantités et les températures des charges amenées à la colonne maintiennent efficacement la tête de cette dernière à une température permettant d'extraire la majeur partie des constituants souhaités.
