Inventor: MARTINESCO DIMITRI
IPC: A41H37/00
Filed: 1990-09-12
Abstract: B R E V E T D ' I N V E N T I O N INVENTEURS: MARTINESCO Dimitri, NEBOT Guy, SOIA Christian MANDATAIRE: Jean BLUM APPAREIL POUR FIXER LES BOUTONS AMOVIBLES A RESSORT DU CONTENU TECHNIQUE DE L'INVENTION La présente invention décrit un appareil destiné à poser des boutons amovibles à ressort, notamment hélicoïdal, caractérisé par le fait qu'il est muni d'un socle et d'un dispositif qui fait subir aux boutons à poser une rotation autour de leur axe combinée avec une translation. Le mouvement peut être provoqué par une simple rotation d'une pièce de l'appareil générée par un dispositif moteur situé dans l'axe du bouton à poser ou hors de cet axe, par exemple dans un axe parallèle en transmettant la rotation à l'aide d'une came. Le mouvement de pose du bouton peut aussi être généré par un simple mouvement de translation et dans un exemple on provoque la rotation du bouton grâce à des billes coin?des entre des encoches pratiquées dans l'une des pièces en translation et les filets d'une vis qui porte le bouton à poser. L'appareil peut être muni d'un chargeur dans lequel on a au préalable empilé des boutons, et dans ce cas, on décrit un fond pourvu d'une membrane souple avec un orifice d'où sortent la collerette et les spires libres du bouton à poser et des fentes rayonnantes qui délimitent des secteurs qui s'écartent lorsqu'on retire l'appareil après avoir posé un bouton. L'appareil peut du reste n'être composé que du chargeur dont on se sert notamment comme d'un tourne-vis.

Patent CA-2061376-A1 (CA)
Inventor: PERRITT RICHARD G
IPC: B01D35/06
Filed: 1992-02-17
Abstract: A plurality of magnets contained or held within a flexible nonmagnetic strap which is wrapped around the exterior casing of a filter for liquids which are typically lubricating fluids. The magnetic fields created by the magnets attract and capture magnetic particles suspended within the lubricating fluid against the interior wall of the filter casing. The captured particles include particles too small to be captured by the filter itself but large enough to cause additional wear of parts if allowed to continue circulating within the fluid. The flexible strap containing the magnets may be wrapped around the filter any number of times thereby enabling the magnetic filter strap to fit numerous filter sizes. The flexible strap may also be made stretchable, with adjustable or non adjustable joining devices at the ends or may also have the ends permanently joined. This also enables the magnetic filter strap to fit filters of various sizes. The magnetic filter strap is reusable from filter to filter and can be used on spin-on or cartridge type oil filters used in automotive and industrial applications.

Abstract: DIAMOND PELLETS AND SAW BLADE SEGMENTS MADE THEREWITH                         ABSTRACT OF THE DISCLOSURE The present invention addresses the foregoing problems and many more in the diamond saw blade and segment art. One aspect of the present invention comprises a method for making handleable, strong, discrete metal-clad abrasive particle pellets. This method comprises the steps of (a) spraying onto a bed of gas-fluidized abrasive particles a slurry of metallicpowder, a binding agent, and a volatile solvent, for a time until each abrasive particle is coated with at least about 20 wt-% of said metallic powder, (b) recovering said metal powder-coated abrasive particles substantially devoid of said volatile solvent; and (c) heading said recovered coated abrasive particles under conditions to form a sintered continuous metal coating enveloping said abrasive particles. The resulting sintered metal-clad particle pellets form another aspect of the present invention.      Another aspect of the present invention comprises: (a) placing a plurality of abrasive pellets, each comprising an abrasive particle coated with at least about 20 wt-% sintered metal, and a source of braze metal in a mold cavity; and (b) heating the contents of such mold cavity under conditions comprising temperature and pressure to form an abrasive particle-containing metal saw blade segment containing interconnected porosity. The resulting saw blade segment forms another aspect of the present invention. A further aspect of the present invention is a method for improving the sawing of substrates with saw blades retaining abrasive particle-containing metal saw blade segments having a lengthwise extent which follows the cutting edge of said saw blade. This method comprises: (a) placing in a mold cavity a plurality of abrasive pellets, each comprising anabrasive particle coated with at least about 20 wt-% metal, in an array of at least two rows parallel with the lengthwise extent of said segment, and a source of braze metal; and (b) forming said saw blade segment from said pellets and braze metal in said mold cavity.

Abstract: Dans les procédés industriels de fabrication de composites à matrice métallique à partir de l'état liquide ou de l'état pâteux, on incorpore, habituellement, les particules de céramiques dans le métal liquide par différents procédés de brassage mécaniques. L'utilisation de procédés mécaniques engendre plusieurs problèmes au niveau de la production affectant la reproductibilité des produits. Dans la présente invention, la technologie te fabrication de composites à matrice métallique se fait par circulation créée par une différence de ppression, utilisant aucun élément de brassage mécanique pour incorporer les particules. Un tel procédé de fabrication élimine toutes les possibilités d'oxydation du matériau durant l'étape d'incorporation des particules et les étapes subséquentes de mise en forme finale ainsi que donne une meilleure reproductibilité de la production et une meilleure homogénéité de la composition du matériau que les produits issus des sytèmes à brassage mécanique.L'incorporation des particules se fait en de temps trés courts.
