Title: Method for segmentation of a digital picture
Inventor: BAATZ MARTIN
IPC: G06T7/11
Filed: 1998-02-10
Abstract: What is disclosed is a method for segmentation of a digital  picture  consisting of  a multiplicity of  single picture  elements  (pixels),  wherein  in  particular  for digital picture processing and/or for object and pattern recognition picture segments are formed in that whenever single contiguous picture elements and/or picture segments are  combined  or  already  formed  picture segments  are modified by segregation of picture elements and/or partial picture  segments  if  one  feature or  several  features  of contiguous picture elements or picture segments are judged to be conforming (identical or similar) or not conforming by means of specific homogeneity criteria. As a homogeneity criterion  for  each  examined  feature,  a  tolerance  is referred to within which the feature values of the two picture  elements  or  picture  segments  in  question  may differ, with the segmentation iteratively being repeated through  all  picture  elements  or  picture  segments.  The method  is  capable  of  segmenting  a  picture  having  any dimensionality in a desired resolution and/or concurrently in several different degrees of resolution.

Title: Flushometer piston
Inventor: CARROLL DANIEL J
IPC: F16K31/383
Filed: 1998-08-21
Abstract: A flush valve includes a body with an inlet, an outlet, a valve seat at the outlet, and a piston movable in the body toward and away from the valve seat to control flow through the outlet. The piston has a chamber and there is a refill orifice in the piston connecting the chamber with the body inlet. Pressure in the chamber maintains the piston closed upon the valve seat. A relief valve in the piston vents the chamber to the outlet to permit the piston to move away from the valve seat to open flow from the inlet to the body outlet. The piston has a guide portion which extends downstream of the valve seat when the piston is in the closed position. The guide portion of the piston has a plurality of outwardly extending axial ribs, the outer surface of which is radially in alignment with the path of flow through said valve seat. The piston area between the ribs is closed by a skirt to confine the path of flow exteriorly of the piston portion to provide a defined flow path through the valve seat from the inlet to the outlet.

Patent CA-2255371-A1 (CA)
Inventor: JACOBS GARRY E
IPC: B01F23/00
Filed: 1998-12-09
Abstract: A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface.  Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate. The distribution apparatus can be used in the reaction vessel without the swirl chamber and rough distribution system, e.g., at the top of a vessel.

Abstract: L'invention concerne un dispositif de serrage pour maintenir un article présentant une partie à fixer, ayant une forme et une taille prédéterminées. Le corps du dispositif est au moins partiellement en alliage superélastique, avec une ouverture légèrement plus petite que la partie à fixer. Le corps du dispositif de serrage comprend un système de fixation, éventuellement sous la forme de petits trous, auquel peut s'appliquer une force externe d'étirage dans un sens et un ordre de grandeur suffisants pour induire une extension élastique de l'ouverture et y accueillir la partie à fixer de l'article. Le relachement de ladite force d'étirage entraîne une contraction élastique de l'ouverture qui, reprenant sa taille initiale, a un effet de serrage sur la partie à fixer. On décrit aussi un instrument pouvant être fixé au corps du dispositif de serrage, pour appliquer la force d'étirage au corps proprement dit.

Filed: 1997-07-07
Abstract: L'invention concerne des systèmes de résines époxy, présentant une bonne flexibilité ainsi qu'une bonne résistance aux chocs, qui sont modifiés afin d'obtenir une meilleure résistance aux solvants. L'incorporation d'un segment polyalkylèneoxyde de poids moléculaire supérieur à 500 confère une meilleure résistance chimique sans porter atteinte aux propriétés mécaniques. Pour obtenir de tels résultats, un polyol alcoxylé de faible poids moléculaire est mis à réagir avec un anhydride d'acide polycarboxylique pour produire le semi-ester qui est ensuite utilisé pour synthétiser la résine époxy flexibilisée par formation d'adjuvants avec des éthers polyglycidyle. Les résines époxy flexibilisées ainsi que les oligooxyalkylènes fonctionnalisés par l'acide sont également revendiqués.
