Patent CA-2290470-A1 (CA)
Title: Procede d'autocalibrage d'une suspension a amortisseur reglable
Inventor: HOLZHEIMER JOHN C
IPC: B60G17/019
Filed: 1998-06-11
Abstract: L'invention concerne un procédé de calibrage automatique d'une commande (44) pour système amortisseur réglable (40), par exemple la suspension et le système amortisseur du siège ou de la cabine de conduite d'un camion. Ce procédé consiste tout d'abord à recevoir un signal de mise en marche pour le comparer à certains critères, de manière à s'assurer si le calibrage doit vraiment être effectué. On déplace ensuite le siège (20) ou tout autre corps (par exemple la cabine de conduite d'un véhicule) vers une première position limite, dans laquelle un capteur (50, 50') lit un signal de position, puis vers une seconde position limite, dans laquelle c'est un autre signal de position qui est lu. On calcule de préférence un point intermédiaire, ou une position neutre, à partir de ces signaux de position mesurés, le siège (20) ou l'autre corps étant alors déplacé vers cette position neutre. On détermine ensuite une plage des valeurs de déplacement à partir de ces premier et second signaux de position. Les limites des butées sont calculées de préférence sur la base de ces valeurs limites, et idéalement en tant que fractions prédéterminées de ladite plage des valeurs de déplacement, toutes ces valeurs étant mémorisées pour être ensuite utilisées par ledit système amortisseur réglable (40).

Title: A method and an apparatus for bringing together and joining plastic cards and card carriers
Inventor: WEINMANN KARLHEINZ
IPC: B42D25/00
Filed: 1998-06-15
Abstract: In a method and an apparatus for bringing together and joining plastic cards, which are provided with an identification mark, and printed card carriers associated with the respective plastic cards, data sets with identification marks, which are associated with the plastic cards, are first provided and each data set has associated therewith a print job number. The plastic cards and the printed card carriers, which have a print job number printed thereon, are provided in a presorted sequence and the identification mark of a plastic card and the print job number of a card carrier are detected. On the basis of the data set provided, the plastic card, whose identification mark has been read, has associated therewith a print job number, whereupon it is determined on the basis of this print job number whether the plastic card which is about to be joined and the card carrier match one another. If this is the case, the plastic card and the card carrier are brought together and joined.

Title: Method for preparing polyether polyols
Inventor: DIETRICH MANFRED
IPC: C08G65/30
Filed: 1998-08-05
Abstract: The invention relates to a method for preparing polyether polyols by reacting polyols with epoxides in the presence of basic catalysts. The method comprises the following steps: the polyether polyols, which contain basic catalysts, are treated with OH-functional solid compounds of metals from the III to VIII  groups of the periodic table of the elements (Mendeleev), which are insoluble in the polyether polyols and have BET-surfaces of 10-1000m2/g. The solid inorganic compounds, loaded with the basic catalysts, are isolated from the polyether polyol and are introduced into the reaction of the polyols with the epoxides; conversely, the isolated inorganic compounds, which are loaded with the basic catalysts, are brought into contact with the polyols which are to be introduced into the reaction with the epoxides. The polyols are then separated from the inorganic compounds and introduced into the reaction with the epoxides.

IPC: B25D1/08
Filed: 2000-05-24
Abstract: A hammer having a deformable main striking surface for striking an object while allowing the main striking surface to substantially conform to the outer contour of the object being struck.      The hammer includes a hammer head mounted to a handle. The hammer head includes a set of plates each having end peripheral edges. The end peripheral edges of adjacent plates together form the deformable main striking surface.    The plates are mounted so as to be slidable relative to each other within a predetermined plate sliding range.    The hammer head is preferably mounted to the handle so as to allow relative angular movement between the hammer head and the handle during hammering motions.  The hammer head is attached to the handle by an attachment rod loosely fitted within a handle channel. The clearance created between the attachment rod and the handle channel allows for the relative angular movement between the hammer head and the handle.

Title: Procede de purification pour alliages organometalliques
Inventor: JONES KARL R
IPC: C07F17/00
Filed: 1999-03-11
Abstract: L'invention concerne la séparation entre des alliages organométalliques du groupe 4 et les matériaux goudronneux hydrocarbonés qui se forment généralement durant la synthèse de ces produits. Pour cela, on combine solvant organique polaire ainsi que solvant organique non polaire avec le mélange impur - les solvants en question étant sensiblement incompatibles entre eux (par exemple, acétonitrile et hexanes) - de manière à obtenir après combinaison au moins deux phases séparées, à savoir (i) une phase polaire principalement à alliage organométallique et solvant polaire, et (ii) une phase non polaire principalement à solvant organique non polaire et matériau goudronneux hydrocarboné, avec une certaine part d'alliage organométallique. Après séparation desdites phases, on extrait la phase non polaire via un solvant organique polaire frais, pour constituer une autre phase polaire principalement à alliage organométallique et solvant polaire. L'alliage organométallique peut ensuite être récupéré à partir des phases polaires, par exemple aux fins de distillation.
