Abstract: La présente invention concerne un procédé et un appareil permettant de mettre en échec des projectiles animés d'une grande vitesse. Une pluralité de disques de mêmes dimensions et d'une épaisseur supérieure à 0,1 pouces sont calandrés en une pluralité d'emplacements. Chaque emplacement calandré présente un rayon de courbure sensiblement égal au rayon de courbure du disque. Ces disques sont disposés en un réseau d'imbrication à plusieurs rangées de façon que chaque disque d'une rangée se trouve sensiblement dans l'alignement des autres disques de la même rangée, chevauche un emplacement calandré d'un disque d'une rangée au-dessus de sa rangée, et que son emplacement de calandrage soit partiellement recouvert par un disque de la rangée en dessous de la sienne. On colle ensuite le réseau d'imbrication contre un substrat souple à forte résistance à l'étirement, et l'on recouvre l'ensemble d'une seconde couche à forte résistance à l'étirement de façon que le réseau d'imbrication vienne s'envelopper entre le substrat et la seconde couche.

Abstract: A digital video processing method and an apparatus thereof are provided. The method for processing digital images received in the form of compressed video streams comprising the step of determining a region intensity histogram (RIH) based on information on motion compensation of inter frames. The RIH information is obtained based on the motion compensation values of inter frames, and the RIH information is a good indicator of motion information of a video scene. Also , since the RIH information is quite a good indictor of intensity of the video scene, video streams having similar intensities can be effectively searched by searching for similar video scenes based on the RIH information obtained by the digital video processing method.</SDOAB >

Abstract: A method of reducing the solubility of calcium sulfate (or sulphate) dehydrate (CaSO4~2H2O) and method of making the same are disclosed. The suspension of needle-shaped (acicular) calcium sulfate dehydrate particles is prepared by mixing freshly calcined calcium sulfate hemihydrate (CaSO4~1/2H2O), having an average particle size between 1 and 100 micrometers, and water in a reactor at medium to high shear rate, with either no additives or together with acids or with calcium or sulfate containing additives. The average length and width of the resulting calcium sulfate dehydrate particles are then about 5 to 35 micrometers and 1 to 5 micrometers, respectively. The calcium sulfate dehydrate particles of reduced solubility are obtained using a calcium chelating agent, with or without the addition of a weak acid. The resulting product is a suspension of calcium sulfate dehydrate that can be used as a filler in papermaking, more particularly by being directly added to the pulp furnish before the paper sheet formation. These particles have a high retention and provide improved optical properties with minimal filler losses due to solubility.

Abstract: Disclosed is a method and apparatus for determining stone cells within a sample of wood pulp or paper. According to the instant invention a portion of the sample is irradiated with light at a predetermined wavelength or within a predetermined range of wavelengths. The incident light causes those areas of the sample that are occupied by stone cells to fluoresce strongly relative to the background matrix of wood pulp or paper. The strongly fluorescing stone cells are registered digitally using a detector, or are observed visually by an operator viewing the sample through an ocular device. The absolute number of stone cells per unit area or a stone cell size-distribution-plot is obtained using one of automated or manual image analysis.

Abstract: L'invention concerne un capteur et un procédé de fabrication associé. Ce capteur est destiné à être implanté dans un corps et est constitué d'un substrat pourvu de découpes en forme de rainure destinées à former une région recourbée vers le bas dans le substrat; et au moins une électrode de capteur constituée d'une ou plusieurs couches. De préférence, l'épaisseur du substrat se situe dans la plage comprise entre approximativement 25 mu  et 350 mu  mais elle peut se situer également dans la plage comprise entre 5 mu  et 750 mu . Le capteur peut être incorporé dans un assemblage de capteur comprenant un aiguille à fente. Les rainures formant la région recourbée vers le bas permettent au substrat de glisser dans l'aiguille pourvue d'une fente assez grande pour permettre le passage de la région recourbée vers le bas. Cependant, une région n'étant pas recourbée vers le bas ne peut pas sortir de l'aiguille par la fente. La fente de l'aiguille permet également à la région recourbée vers le bas du substrat de glisser dans la fente.

Title: Acides dihydro et hexahydro isoalpha avec un rapport eleve d'isomere trans par rapport au cis, leur production et produits les contenant
Inventor: TODD PAUL H
IPC: C07C45/00
Filed: 2001-02-20
Granted: 2007-09-18
Abstract: L'invention concerne des formes inconnues d'acides dihydro (DHIA) et hexahydro (HHIA) isoalpha avec un rapport élevé d'isomère trans par rapport au cis, ainsi qu'un procédé de production de ces acides. Elle concerne également les solutions aqueuses de ces acides à 5, 10, 20 % et plus, qui sont claires et ne précipitent pas en raison de leur solubilité à température ambiante dans l'eau douce. Ceci est dû au rapport élevé d'isomère trans par rapport au cis. Contrairement à l'état antérieur de la technique dans lequel les acides sont essentiellement des isomères cis, les acides de l'invention ne provoquent pas de trouble à la fois à un pH neutre dans l'eau et à des concentrations de 1 % à 2 % et plus élevées. L'invention présente l'avantage par rapport à la technique antérieure d'obtenir les acides DHIA et HHIA sous forme de solutions stables, non précipitantes, à des concentrations pratiques comprises entre 5 % et environ 40 %, qui ne requièrent aucun chauffage à environ 50 DEG  à 90  DEG C et plus, avec agitation, aux fins de dissolution de précipités. Les produits à forme trans prépondérante de l'invention peuvent être mélangés avec des acides isoalpha- et tétrahydro-isoalpha.

Abstract: The present seal system (8) is in two parts, that of an elastomer energizer (12), which may be in the shape of a square ring, o-ring, or an other custom design for energizing the seal system (8), and that of a seal element (18) having a particular geometry and composition. The geometric layout of the seal element ensures firm contact between the seal and groove bottom, independently of the seal pressure and radial position of the moving part, and concentrates contact forces against the moving part by means of a seal apex (24). The influence of the energizer (12) is balanced out by positioning the seal apex (24) near the axial position of the center of the energizer (14). The seal apex (24) itself is defined by an inlet angle (b) upstream of the apex of preferably more than 30°  to the moving part, and a downstream slip angle (a) of greater than 5°  preferably greater than 7°.
