IPC: C11D3/37
Filed: 2002-07-10
Abstract: L'invention concerne des produits de traitement du linge qui comportent un agent bénéfique polymère greffé et au moins une substance nettoyante supplémentaire, ledit agent, de préférence, facilitant avantageusement le lavage ou l'entretien de textiles. Il comprend un squelette polysaccharide et plusieurs chaînes greffées s'étendant du squelette, chaque chaîne greffée ayant un degré de polymérisation situé entre 5 et 250. Le polymère greffé est sensiblement libre de réticulation et présente un degré de substitution de greffes au niveau de l'échantillon global se situant dans la gamme de 0,02 à 1,0. On peut préparer les copolymères de polysaccharide greffés par des techniques de polymérisation à radicaux libres du type vivante qui permettent de réguler le degré de substitution, la composition greffe/co-bloc et la structure.

Abstract: An improved structure foldable assembly-type lamp shade comprised of a top ring at the uppermost end of the lamp shade, a bottom ring of larger circumference than the top ring, and frame members propped between the top ring and the bottom ring. The bottom ring has fixing mounts consecutively disposed at the frame member locations that provide for the assembly and positioning of the frame members, with the fixing mounts at the support member installation locations having different type connection sections based on the respective type of fixing mount arrangement utilized. When packaged, since the frame members can be first folded down and whorled into a flat state such that the frame members and the top ring are stacked on the bottom ring, the lamp shade of the present invention occupies the smallest physical assembly area to facilitate ease of assembly and, furthermore, the resulting minimized storage area effectively reduces shipping costs.

Title: Method for assembling prepreg stacks having exact weight for producing smc components
Inventor: NORDMANN BERNHARD
IPC: B29C70/46
Filed: 2002-08-14
Abstract: The invention concerns a method for producing SMC components, from an adapte d amount of fibrous synthetic reactive resin available in the form of defined cut-out prepreg components. Said method comprises the following steps: introducing the prepregs in a specific number of layers into a heated formin g tool of a moulding press; extruding the resin/fibrous composition in the closed forming tool, so as to obtain a SMC component; heat-hardening the latter; then removing it from the forming tool. The invention aims at producing with high accuracy, during each production cycle, prepreg stacks having a constant weight, despite the variable basis weight of the prepregs. Therefor, a reference cut-out component with constant shape and dimensions i s cut to size and weighed each time separately, when the cut-out components ar e weighed. The dimensions with respect to the basis weight of the adjusting components to be cut are mathematically determined, from the weight and dimensions of the cut-out reference component, to obtain accurately the theoretical weight of the resin composition to be input. Two different techniques are described: in one technique, the prepreg is introduced into t he forming tool in multiple layers, and in the other technique, it is introduce d therein in a single layer.

Patent CA-2483688-A1 (CA)
Inventor: AULD DOUGLAS
IPC: C12Q1/48
Filed: 2003-05-14
Abstract: A method for determining the level of kinase activity or phosphatase activity in a sample without the use of antibodies or radioactive labels is disclosed.  The method employs a fluorescently-labeled phosphorylatable reporter peptide that is capable of being cleaved by a protease only when the peptide is in an unphosphorylated state. A change in fluorescence characteristics is an indication that the peptide is cleaved and, therefore, in an unphosphorylated state. Thus, the level of protease cleavage, as measured by the fluorescence change, provides a direct measure of phosphatase activity whereas the level of kinase activity is inversely proportion to the level of protease cleavage. The method is particularly well suited to high throughput screening, for example, for screening compounds which modulate kinase or phosphatase activity.

Abstract: A golf club is manufactured according to a method in which a radially compliant crush sleeve is interposed between the shaft tip and howl of the club head. The crush sleeve is fabricated from a strip of metal formed into a substantially cylindrical metallic band with a plurality of radially-extending dimples or corrugations that grip the shaft. The crush sleeve is retained either in an undercut region in the hosel bore, on a mandrel extending from the hosel, or on a pilot shaft at the tip of the golf club shaft. After the interface between the shaft and hosel is coated with an adhesive, the shaft is assembled to the hosel with the crush sleeve squeezed in between. The crush sleeve secures the shaft to the club head with sufficient rigidity to allow the adhesive to set while maintaining the appropriate axial and rotational alignment.

Title: Hepatitis c viral-like particle purification
Inventor: SAUNIER BERTRAND
IPC: C12Q1/68
Filed: 2003-08-18
Abstract: Methods for obtaining HCV complexes and HCV-like particles comprising HCV  structural genes are provided. In one method, cells containing HCV-like particles are lysed with digitonin in the presence of protease inhibitors.  Polyethylene glycol is slowly added to the lysate, to provide a precipitate that comprises complexes of the HCV structural proteins associated with lipid vesicles or micelles and complexes comprising viral structural proteins in the form of insoluble aggregates. In another method, the lysate is centrifuged through a sucrose cushion. Preferably, the pellet is then subjected to equilibrium ultracentrifugation, to provide a preparation of HCV-like particles that are heterogenous in size. The third method comprises subjecting the infected cells to hypertonic/hypotonic shock, and lysing the cells with digitonin in the presence of protease inhibitors. The lysate is pelleted and fractionated to provide a population of HCV-like particles that are substantially homogenous and have an average diameter of about 50 nm. As used herein the term " substantially homogenous" means that the shape of the particles are similar and that the size of the particles vary by 10% or less.  Methods of using the HCV complexes and HCV-like particles as screening tools, diagnostic tools, and immunogenic compositions are also provided. Methods of treating patients exhibiting symptoms of HCV infection with compounds or substances that interfere with binding or internalization of the present HCV-like particles to asialoglycoprotein receptors are also provided.
