Patent CA-2256579-C (CA)
Inventor: AKSELA REIJO
IPC: C01B15/037
Filed: 1997-05-30
Granted: 2005-07-26
Abstract: The invention relates to a process for the bleaching of chemical pulp, in which process the pulp is delignified with a peracid and additionally the pulp is chelated in order to bind heavy metals, such as Fe, Mn and/or Cu, into a chelate complex. According to the invention, the chelating is carried out using a chemical which has been selected from a group consisting of N-bis-((1,2-dicarboxy-ethoxy)- ethyl)-amine, N-bis-((1,2-dicarboxy-ethoxy)-ethyl)-aspartic acid and N-tris- ((1,2-dicarboxy-ethoxy)-ethyl)-amine, as well as the alkali metal and earth-alkali metal salts thereof, and the peracid and chelating treatmen ts are carried out simultaneously by combining the peracid and the said chelating chemical in the same solution phase. In the bleaching sequence the treatment according to the invention may follow, for example, an ozone delignification and precede an alkaline peroxide step, and in the latter case a magnesium compound, such as MgSO4, may be added to the pulp before the alkali step.

Abstract: L'invention se situe dans le domaine des vaccins et des préparations immunogènes. Normalement, dans ces préparations, les antigènes et les composés supports sont irréversiblement couplés par une liaison stable. L'invention, au contraire, concerne des vaccins et des préparations immunogènes dans lesquels l'antigène (qu'il soit une protéine, un peptide, un hydrate de carbone ou n'importe quelle autre molécule pouvant être utilisée comme antigène en vue d'une immunisation/vaccination) et le composé support sont couplés de manière réversible et labile, par ce qu'on appelle une liaison labile. Etonnamment, comme cela a été démontré dans la partie expérimentale de cette demande, un antigène faiblement immunogène par lui-même peut ainsi provoquer une meilleure réponse qu'avec les méthodes dans lesquelles l'antigène et le composé support sont liés par une liaison stable.

Abstract: La présente invention concerne des immunoglobulines humanisées possédant une spécificité de fixation à l'égard de l'intégrine  alpha 4 beta 7, et comprenant une région de fixation d'antigène d'origine non humaine (par exemple, des rongeurs) et au moins une portion d'une immunoglobuline d'origine humaine (par exemple, une région structurale humaine ou une région constante humaine). Dans un mode de réalisation, l'immunoglobuline humanisée peut entrer en compétition avec Act-1 murin pour se fixer sur l'intégrine  alpha 4 beta 7 humaine. Dans un mode de réalisation préféré, la région de fixation antigénique de l'immunoglobuline humanisée comprend chacune des régions de détermination de complémentarité de chaînes légères et lourdes de l'anticorps Act-1 murin. La présente invention concerne encore une chaîne légère ou lourde d'immunoglobuline humanisée, des acides nucléiques isolés comprenant une séquence codant pour une immunoglobuline ou une chaîne d'immunoglobuline humanisée de la présente invention (par exemple, un anticorps à chaîne simple), des constructions comprenant un acide nucléique de l'invention, ainsi que des cellules hôtes comportant un acide nucléique de l'invention, utiles dans un procédé de préparation d'une immunoglobuline humanisée. On peut utiliser ces immunoglobulines humanisée dans des applications diagnostiques et thérapeutiques chez l'homme, par exemple pour limiter l'infiltration lymphocytaire (notamment par recrutement et/ou accumulation) dans des tissus de muqueuses.

Abstract: A multiplier array is modified to perform interpolations. The interpolations  use a normalized first operand A between 0 and 1. The interpolation is the function B*A+C*(1-A). Standard multipliers accept two operands as inputs, bu t interpolations require 3 operands (A, B, C). The AND gates in Booth encoders  (30) in a standard multiplier array are replaced by multiplexers. Each multiplexer selects a bit from one of the two operands (B or C) based on a b it of the first operand A. The interpolate operation multiplies the first opera nd A by the second operand B while simultaneously multiplying the bit-wise inverse of the first operand A' by the third operand C.

Abstract: A refrigerator door has an outer door panel having an outer skin with rearwardly extending peripheral vertical and horizontal side walls.      Four corners are located between adjacent horizontal and vertical side walls. An inner door liner is secured to the outer door panel to define a cavity between the inner liner and the sheet. Cut-out sections are formed in the horizontal side walls adjacent the corners to define exposed edges extending along the vertical side wall, the horizontal side wall and outer skin of the door. A reinforcing corner bracket is positioned within the cavity adjacent each cut-out section assuming normal loading forces associated with the door. Epaulet covers extend over the cut-out sections and the exposed edges. The epaulet covers each have a flange depending therefrom and adapted to overlay an outside surface portion of the outer door skin and the vertical side wall. The epaulet covers have a plurality of ribs extending therefrom adjacent the flange for engaging the inside of the outer door skin and the vertical side wall. The epaulet cover has fasteners comprising an extension and hook shaped end that pass through slotted apertures in the corner bracket permitting the hook shaped surface to engage a rear side of the corner bracket. The slotted apertures are sized larger than the fasteners to permit lateral movement of each epaulet cover relative to its corresponding corner bracket as the epaulet cover is secured over the at least one exposed edge.
