Patent CA-2234665-C (CA)
Inventor: MORRIS KIMBERLEY
IPC: H01H71/74

Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated armature element mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated armature element which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated armature element of the armature extends. A radially enlarged slug on the free end of the elongated armature element of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits. A non-magnetic spring clip firmly retains the magnetic frame in a recess in the circuit breaker housing.

Abstract: In  an  apparatus  and  method  for  creating  a three-dimensional model of an object, images of the object taken from different, unknown positions are processed to identify the points in the images which correspond to the same point on the actual object  (that is  "matching" points), the matching points are used to determine the relative positions from which the images were taken, and the matching points and calculated positions are used to calculate   points   in   a   three-dimensional   space representing points on the object.  A number of different techniques are used to identify the matching points, and a number of solutions are calculated and tested for the relative positions, the solution which is consistent with the largest number of matching points being selected.          In  one  matching  technique,  edges  in  an  image  are identified by first identifying corner points in the image and then identifying edges between the corner points on the basis of edge orientation values of pixels, the edges are processed in strength order to remove cross-overs,  the  images  sub-divided into  regions  by connecting points at the ends of the edges on the basis of the  edge  strengths,  and  matching  points  within corresponding  regions  in  two  or  more  images  are identified.

Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item. The extracted item is then laundered in a laundry detergent composition containing a brightener. The resulting white fabric items have substantially improved whiteness when compared to similarly soiled items laundered in conventional processes.

Filed: 1997-11-25
Granted: 2004-03-30
Abstract: La présente invention a trait à un moyeu de roue à utiliser en combinaison avec des meules classiques à moyeu déporté. Le moyeu comprend une douille d'entrée de forme généralement cylindrique. Un rebord discoïde s'étend radialement depuis une partie médiane de la douille jusqu'à la lèvre périphérique. La douille est conçue pour s'étendre dans un alésage central de la roue, de sorte que la lèvre vienne en contact avec la face d'appui de la roue avoisinant la circonférence la plus éloignée du moyeu déporté. Une extrémité de la face de rectification de la douille peut se rabattre radialement vers l'extérieur de manière à venir en contact avec la face de rectification avant de la roue et saisir mécaniquement la roue entre l'extrémité de la face de rectification et le rebord. Ledit rebord forme, avec la lèvre et la face d'appui, une cavité dans laquelle la résine époxyde est placée pour que le moyeu soit chimiquement fixé à la roue. La combinaison de la fixation mécanique et de la fixation chimique fixe de manière adéquate le moyeu à la roue, sans que le rebord s'étende nécessairement au dessus de la partie coudée. La présente invention a par conséquent l'avantage de permettre à la roue d'être rectifiée par rapport à la partie coudée, en vue de son utilisation dans des conditions optimales.

Abstract: A method of searching a table in a database management system for free space for inserting a new record into the table. The table resides in a storage media, and includes a series of pages capable of storing a plurality of records. The table has a clustering index defined in a column of the table. The new record has a new record attribute for storing in the column of the table when the new record is stored in the table. The method comprises searching for a target page in the series of pages, the target page being selected to maintain clustering when the new record is inserted thereon. Once the target page has been located, it is searched for sufficient free space to accommodate the new record. If sufficient free space is found on the target page, then the new record is inserted on the target page. If sufficient free space is not found on the target page, then a target neighbourhood of pages in the series of pages is searched for sufficient free space to accommodate the new record. The target neighbourhood of pages surrounds the target page. If sufficient free space is found on a page in a target neighbourhood of pages, then the new record is inserted on to this page in the target neighbourhood of pages. If sufficient free space is not found in the target neighbourhood of pages, then the method further comprises searching for sufficient free space to accommodate the new record outside the target neighbourhood of pages. If sufficient free space is found outside the target neighbourhood of pages, then the new record is inserted on a non-neighbouring page outside the target neighbourhood of pages. If sufficient free space is not found outside the target neighbourhood of pages, then a new page having the new record is appended to the end of table.
