Title: Magnetic pulse welding method and apparatus for sealing a vessel and a sealed vessel
Inventor: GAFRI OREN
IPC: B23K20/06
Filed: 2004-07-07
Abstract: A pulsated magnetic welding method and a welding induction coil for sealing a vessel (10) are provided. The method includes providing a vessel's body (11) having an open end (12) a cover (13) including a welding part and a brim part (15). A diameter of the cover (13) at the welding part (14) is less than the diameter of the vessel's body (11) for providing an air gap (16) between the vessel's body (11) and the welding part (14). The cover (13) is placed within said open end (12) of the vessel's body (11). A welding induction coil (18) is provided around the vessel's body (11) at the place where the welding part (14) of the cover (13) is located. The welding induction coil (18) is energized to generate a pulsed magnetic force sufficient to cause bending a portion (19) of the vessel's body (11) in a radially inward direction around the cover (13) in the air gap (16). The pulsed magnetic force has such a value so to provide mutual diffusion of atoms of the vessel's body (11) and the cover (13) at their impact, thereby to weld the vessel's body (11) and the cover (13) to each other.

Patent CA-2560056-A1 (CA)
Title: Vacuum pill singulator
Inventor: RHODES RAYMOND
IPC: B65B5/10
Filed: 2005-03-15
Abstract: A singulating disc (20), carried by a housing, has a plurality of openings (28) around its periphery. The disc (20) rotates vertically through a pickup chamber of a hopper (12) carried by the housing. A vacuum is pulled through the openings (28) by a pump which is connected to the disc (20). Items are placed in the hopper (12) and, via gravity, fall to the bottom of the hopper (12) where they contact the periphery of the rotating disc (20). The vacuum at the openings attaches an item and holds it while the disc (20) rotates. At the top of the disc's rotation, a diverter (26) directs the item into a path depending on the results of a fragment detection and/or counting mechanism.  Items that are allowed to pass by the diverter (26) are scraped off the disc into another path by a scraper (15). Negative pressure is used to singulate and count a multitude of sizes and shapes of items with no calibration.  Retractable paddles (62), a vacuum management system, and RFID tags may be incorporated. The paddles (62) aid in the pickup and agitation of the items while the vacuum management system conserves the vacuum capacity necessary to pickup and singulate items. The RFID tags may contain information such as the number of items left in the hopper, a par level for that item, an expiration date, among others. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

Patent CA-2569866-A1 (CA)
Inventor: LARSEN PETER HALVOR
IPC: H01M8/00
Filed: 2005-06-09
Abstract: SOFC cell comprising a metallic support 1 ending in a substantially pure electron conducting oxide, an active anode layer 2 consisting of doped ceria, ScYSZ, Ni-Fe alloy, an electrolyte layer 3 consisting of co-doped zirconia based on oxygen ionic conductor, an active cathode layer 5 and a layer of a mixture of LSM and a ferrite as a transition layer 6 to a cathode current collector 7 of single phase LSM. The use of a metallic support instead of a Ni-YSZ anode support increases the mechanical strength of the support and secures redox stability of the support. The porous ferrite stainless steel ends in a pure electron conducting oxide so as to prevent reactivity between the metals in the active anode which tends to dissolve into the ferrite stainless steel causing a detrimental phase shift from ferrite to austenite structure.

Patent CA-2576613-A1 (CA)
Inventor: GRIFFIN TIMOTHY
IPC: F02C3/34
Filed: 2005-08-04
Abstract: The invention relates to a method for generating energy in an energy generating installation (10) comprising a gas turbine (12). According to said method, in a first step, a gas containing oxygen is compressed in a compressor (13, 14) of the gas turbine (12); in a second step, the compressed gas is supplied to a combustion chamber (15), with addition of fuel, in view of a combustion; in a third step, the hot waste gas from the combustion chamber (15) is expanded in a turbine (16) of the gas turbine (12), under the effect of work output; and in a fourth step, a branched-off partial current of the expanded waste gas is redirected into a part of the gas turbine (12) located upstream of the combustion engine (15), and compressed. One such method enables a reduction of the CO2 emission with a minimum loss of efficiency, by the separation of carbon dioxide (CO2) from the circulating gas in a CO2 separator (19), and by measures taken to compensate the loss of efficiency in the gas turbine continuous process, related to the CO2 separation.
