Title: Processus de fabrication de materiaux microporeux revetus d'oxyde de metal de terre rare
Inventor: AMR INTERNAT CORP
IPC: B01J29/06
Filed: 2002-09-12
Abstract: La présente invention concerne un processus qui permet d'obtenir une masse particulaire à écoulement fluide, microporeuse et revêtue d'oxyde de métal de terre rare catalytique, la quantité d'oxyde de métal revêtu étant élevée, sans compromettre l'efficacité du matériau. L'oxyde de métal de terre rare déposé sur la surface externe peut représenter de 20 % à 70 % du poids du contenu total équivalent en matériau particulaire microporeux et en oxyde de métal de terre rare. En particulier, une masse particulaire à écoulement fluide zéolitique possédant des charges élevées d'oxyde de métal de terre rare tend à être assez stable. Par exemple, lorsque la masse particulaire à écoulement fluide zéolitique revêtue d'oxyde de métal de terre rare a été thermo-traitée à des températures inférieures à environ 2000 C, puis mélangée en suspension épaisse dans de l'eau, habituellement moins de 30 % du poids d'oxyde de métal de terre rare ( du contenu total équivalent en oxyde de métal de terre rare) est retrouvé pour une lixiviation dans l'eau. On a découvert que ce matériau possède une lixiviabilité minimale lorsqu'il a été traité au dessus de 4000 C.

Patent CA-2008613-A1 (CA)
IPC: A44B18/00
Filed: 1990-01-25
Abstract: An improved releasably securable fastening system for attaching to a complementary receiving surface is disclosed. The fastening system features an engaging means in the form of a hook-shaped tine. The engaging means (30) is longitudinally spaced away from, or above, a substrate (24) by an upstanding shank (28). The engaging means (30) forms an included angle, relative to the perpendicular from the plane of the substrate, which is greater than 180 DEG  so that the engaging means (30) has a reentrant segment (31). The reentrant segment (31) of the engaging means provides for more effective securing of the fastening system to a receiving surface. An engaging means having an included angle greater than 180 DEG provides improved resistance to forces which cause separation of the engaging means from the receiving surface.

Patent CA-2012050-A1 (CA)
Inventor: PFEIFFER NIKOLAUS
IPC: B41F33/00
Filed: 1990-03-13
Abstract: ABSTRACT            In the control of inking in accordance with colorimetric or densitometric quantities, technical process-related influences must not be ignored during printing if it is intended to achieve optimum adaptation to the printing process and to the colour perception of the human eye.            For single- and multi-colour control, therefore, processes are proposed that, in consideration of interdependent parameters - maximum allowable tonal-value increase(s) and maximum allowable layer thickness(es) -, make for a setpoint locus (Set1), said setpoint locus (Set1) being both within the tolerable tonal-value increase(s) (ZSet ? ZTol or ZSeti ? ZToli) and also within the colour tolerance (ETol) or density tolerance (DVTol) or within the tolerance space (TolR). If the setpoint locus (Set1) fails to comply simultaneously with these two independent parameters, the tolerance range of the tonal-value increase(s) is extended and a setpoint locus (Set2 or Opt) is then checked as to whether it now simultaneously satisfies both parameters.

Title: Two cylinder solids handling pump with piston reservoir
Inventor: SCHWING FRIEDRICH
IPC: F04B15/02

Patent CA-2013824-A1 (CA)
Inventor: NOE OSKAR
IPC: B21D1/05
Filed: 1990-04-04
Abstract: A method and an arrangement for continuous tension stretching of thin metal strips. The strip is conducted through a set of brake rollers and a set of pull rollers and the strip is subjected to a stretch-forming or stretch pull operation between the two sets of rollers for stretching the strip in the plastic range, wherein the stretch pull force corresponds to the yield point of the strip material. The strip is subjected between the set of brake rollers and the set of pull rollers only to a stretch-pull which is required for stretching the strip in the plastic range. As a result, transverse elongation during plastic stretching is minimized, so that center troughs no longer occur and, when the strip is longitudinally divided, the strip portions no longer have unequal side lengths.

Patent CA-2016508-A1 (CA)
Inventor: HOOPER DONALD F
IPC: G06F17/50
Filed: 1990-05-10
Abstract: A logic method for accessing rules in a logic circuit synthesis system.  Rules are associated with model instances representing circuit components and contained in a data base.          Application of the rules results in the replacement of one or more of the model instances with other model instances or in alteration of values associated with the model instances or in the alteration of parameter values in the data base.  Model instances are designated as VISIBLE or INVISIBLE.  INVISIBLE model instances are ignored during logic circuit synthesis. That is, the rules associated with INVISIBLE model instances are not tested.  VISIBLE model instances may be NEW or INACTIVE.  All VISIBLE model instances are initially NEW.  If no rule associated with a model instance is TRUE, the model instance becomes INACTIVE.  If at least one rule associated with a model instance is TRUE, one or more model instances are replaced and all inserted model instances and model instances directly connected to the inserted model instances become NEW.    The number of model instances a rule will replace is called a SIZEWIN value of the rule.  During synthesis, each VISIBLE, NEW model instance is paired with its associated rule having the greatest SIZEWIN value.  The instance-rule pairs are grouped by SIZEWIN value and the rules of the groups having the greatest SIZEWIN value are tested first.  The rules of the group having the smallest SIZEWIN value are tested last.  If a model instance has been replaced by a previously executed rule, it is designated as DELETED and its associated, paired rule will evaluate to FALSE.
