Patent CA-2711983-A1 (CA)
Inventor: KINCAID PATRICK D
IPC: C02F11/121
Filed: 2010-07-30
Abstract: La présente invention concerne des systèmes et des procédés pour éliminer de la matière particulaire fine dun fluide, comprenant un séparateur séparant un courant de fluide dentrée en un circuit pour fluide qui déborde et un circuit pour fluide qui ne déborde pas, le circuit pour fluide qui ne déborde pas étant traité par un matériau de liaison qui relie la matière particulaire à gros grains afin de former des particules dancrage portant le matériau de liaison et le circuit pour fluide qui déborde étant traité par un matériau activateur de sorte que le matériau activateur interagit avec la matière particulaire fine pour former des particules activées. Après ces traitements, le circuit pour fluide qui ne déborde pas contenant les particules dancrage portant le matériau de liaison est mélangé au circuit pour fluide qui déborde contenant les particules activées, de sorte quun complexe pouvant être enlevé est produit par lintermédiaire dune installation utilisant la sédimentation, éliminant de ce fait la matière particulaire fine du fluide. Les systèmes et procédés sont particulièrement avantageux pour éliminer la matière particulaire dun courant de déchets fluides à la suite dopérations de traitement de minerais, comme une exploitation minière ou un traitement de minerais provenant de sables huileux.
Patent CA-2714633-A1 (CA)
Inventor: TAYLOR DAVID BRIAN
IPC: B44D3/00
Filed: 2009-01-30
Abstract: A device for cleaning a paint brush B has a shaft (1) is fast in a hub (2) moulded around the shaft. Opposite from the shaft, the hub has a spigot (3) with an external screw thread (4) and a socket (5) having bore (6) opening at the end of the spigot with a counter-bore (7). A step (8) is provided at the inner end of the counter bore. At a larger diameter portion (9) of the hub, it has a small collar (10), providing at an end face (11) an abutment (12). Behind the collar is a circumferential groove (14). A paint brush tip locator (21) is partially housed in the socket (5). It has an inner stem (22), which has a bore (23) with a bottom (24) forming an abutment for a spring (25). The stem (22) is a clearance size in the bore (6).  Outwards of the stem is an external collar (26), which is a clearance size in the counter-bore (7). Within the stem, outwards of the bottom (24), the tip locator has a series of step (28) in a socket (29) opening at the outer end of the locator and sized to receive a paint brush handle tip. This socket end has an outer diameter (30) intermediate the diameter of the stem (22) and the collar (26).  The end portion of the socket is bifurcated with two divergent U-shaped nicks (31). When the tip locator is extended out of the socket or at least no longer accurately radially located by it, it still located by the paint-brush-handle shank (holder 41), now described. It is a plastics material moulding with a tubular portion (42) having an internal screw thread (43), complementary to the external screw thread (4). Two tangs (44) extend from the tubular portion. The tangs are diametrically opposite each other and carry jaws (45) at their distal ends. At their proximal ends, the tubular portion has an internal collar (46), with an internal diameter (47) less than the internal diameter of the thread (43). The diameter (47) is a clearance diameter for the tip socket (29) of the tip locator. Thus the internal collar (46) performs the dual functions of the radially locating the tip locator and longitudinally locating against the action of the spring (25), in a position determined by the position to shank holder with respect to the hub. Long handled brushes can of course hold the tip locator further within the socket of the hub.
