Patent CA-2698176-A1 (CA)
Inventor: PRUD HOMME GUY
IPC: B01D46/24
Filed: 2010-03-30
Abstract: A filtration apparatus comprises a casing defining an inner cavity with an upper cylindrical portion and a lower hopper portion. An inlet feeds gas and solids into the inner cavity and causes movement of the solids in a downward spiral path in the casing. A solids outlet at a bottom of the lower hopper portion outlets the solids from the casing. A gas outlet exhausts gases from the casing.  An annular arrangement of ports in a wall of the lower hopper portion of the casing injects an other gas in the inner cavity. The ports are oriented to guide the other gas into following a partially vertical path into the inner cavity to disrupt the movement of the solids in the downward spiral path to allow a capture of the solid particles by the capturing solids. A gas source is connected to the arrangement of ports.

Title: Methods, apparatus and systems for the handling of empty, flat folded storage bags in preparation for filling with a flowable material
Inventor: MANZON VINCENT RODY
IPC: B65B1/04
Filed: 2011-05-06
Abstract: Empty, flat folded storage bags which may be valve bags are prepared for filling with a flowable material, by seating and stacking a plurality of the bags on a fixed elevation base within a chamber of a bag holding magazine assembly, the resulting stack defining an initial stack rising from a lowermost one the bags on the base to an uppermost one of the bags. In a first cycle of operation, all but the lowermost bag is raised away from the base, the raised bags defining a depleted stack of bags. Then, while the depleted stack remains raised, the lowermost bag is removed from the chamber through a chamber outlet opening. Then, the depleted stack is lowered to seat a new lowermost bag on the base to complete first cycle. The cycle is repeated for each lowermost bag. Each bag removed from the magazine chamber may be conveyed to a bag pick-up position located away from the magazine assembly and, from there, automatically picked with a carrying tool located at the end of a robotic arm and transported to a bag filling station for filling with the flowable material. In the case of valve bags, the valve may be opened by the carrying tool at the time of pick-up.
