Title: Filtre passe-bande a balayage pour analyse d'image par ultrasons
Inventor: MASTERS DONALD
IPC: A61B8/06
Filed: 1999-07-30
Abstract: L'invention concerne un système d'imagerie par ultrasons pourvu d'un filtre (200) passe-bande à balayage qui permet un passage sélectif de signaux acoustiques variables dans le temps. Les signaux acoustiques représentent des artéfacts de réflexion de tissu et de fluide. Le filtre (200) passe-bande comprend deux mélangeurs (218, 226) et deux filtres (220, 228) passe-bande fixes. Les sources de signaux fournissent chacune un signal de référence pour deux oscillateurs locaux. Le premier mélangeur (218) mélange le signal d'entrée et le premier signal (L01) de référence à une première plage de fréquences voulue. Le premier filtre (220) passe-bande fixe comporte une fréquence passe-bande supérieure située au-dessus de la première plage de fréquences, et produit un premier signal (IF1) de sortie filtré. Le deuxième mélangeur (226) mélange le premier signal (IF1) filtré et le deuxième signal de référence (L02) à une deuxième plage de fréquences voulue. Le deuxième filtre (228) passe-bande fixe comporte une fréquence centrale et une largeur de bande ne chevauchant pas le premier filtre (218) passe-bande. Le deuxième filtre (228) passe-bande fixe produit un deuxième signal (IF2) de sortie filtré présentant une caractéristique passe-bande de largeur de bande variable pouvant être scannée, utile pour examiner les caractéristiques variant dans le temps du signal d'entrée. Le filtre passe-bande à balayage comprend également un dispositif de commande servant à commander les première et deuxième sources de signaux en fonction des caractéristiques variant dans le temps considérées.

Title: Foam based product solution delivery apparatus
Inventor: SMAGAC DENNIS EDWARD
IPC: A62C31/12
Filed: 1999-07-19
Abstract: The foam based product solution delivery apparatus is simple in structure and operation and makes use of pressurized gas to power a pressure operated pump to draw the water/foam-concentrate/product(s) from supply tank(s) and propel the resultant solution (foam fluid), with pressurized gas injected therein, through an agitation apparatus that mechanically agitates the water/foam/product(s) solution to create the foam based product solution for transmission to the foam delivery apparatus. Interposed in the delivery apparatus between the pump and the outlet end of the hose, the agitation apparatus functions to significantly increase the foam expansion prior to delivery of the foam through the delivery apparatus. The agitation apparatus comprises an exterior housing inside of which is mounted a set of motionless mixing blades that function to mix and expand the foam. The agitation apparatus not only produces a high expansion of the foam but it also produces a more consistent bubble structure which enhances both the longevity and adhesion of the foam when applied to a structure.

Title: Multi-component yarn and method of making the same
Inventor: KOLMES NATHANIEL H
IPC: D02G3/44
Filed: 2001-04-11
Abstract: A cut-resistant combined yarn is described that includes a wire component.  Kinking and knotting of the wire component resulting from stretching of the wire component during knitting is avoided by encasing the wire component within a cut resistant combined yarn that has a higher stretch resistance than the wire component. The combined yarn includes at least one strand of stainless steel, at first non-metallic strand of an inherently cut-resistant material, and a second non-metallic strand of a cut resistant material, a non-cut resistant material or fiberglass. The non-metallic strands are air interlaced with each other to form intermittent attachment areas along the lengths of the strands. At least one or the other of the strands is a multi-filament strand. During air interlacing operation, the two non-metallic strands encase the stainless steel strand in the non-metallic strands at least in some of the zones. A  composite yarn may be formed by wrapping at least one cover strand wrapped about the combined yarn in a first direction. A second cover strand may be wrapped about the combined yarn in a second direction opposite the first direction.

IPC: B23Q11/00
Filed: 2001-04-25
Abstract: The present invention provides a work table for use with a tool, comprising an inclined work surface, which is substantially planar and is supported by a frame having a base; a gantry movably attached to the work surface and having two ends, a longitudinal axis and extending within a plane parallel to the work surface; a movable tool mount slidably attached to the gantry for removable attachment of the tool wherein the tool mount and the tool have a combined effective weight; a first movement means attached to one end of said gantry for translation of the gantry over said work surface; a second movement means attached to the tool mount for translation of said tool between the ends of the gantry; and a weight counterbalancing means operatively associated with the tool mount for neutralising the combined effective weight. Neutralisation of the weight is accomplished by attaching the tool mount to a counterbalancing system that counterbalances the combined effective weight of the tool and tool mount along the length of the gantry, enabling its smooth movements when the work surface is in an inclined position.
