Patent CA-2623628-A1 (CA)
Inventor: PUVVADA GEORGE
IPC: C22B1/248
Filed: 2008-02-29
Abstract: The invention is a method of separating metals such as zinc, lead and cadmium from iron in secondary feed stocks such as EAF Dust, BOF Sludge, mill scale, iron fines, tire dust and other iron and zinc containing residues and dusts. The method includes the steps of reduction roasting the feed stocks at a volatizing temperature sufficient to volatilize the zinc and other metals into metal fumes but insufficient to volatize iron and then collecting the metal fumes as a metal dust. The metal dust is then leached with a leaching liquid to form a leach liquor and a leach residue. The leach liquor is then purified by zinc dust cementation to form a purified liquor and a zinc dust cement residue. The purified liquor is then separated from the zinc dust cement residue, and a zinc recovery step is then performed on the purified liquor.

Abstract: A seed metering system having a housing and a disk rotatably positioned within the housing and having a plurality of holes extending from a first face to a second face thereof, the holes being substantially uniformly placed from one another around the circumference of the disk and each sized to receive a single seed. A pressure differential is maintained between the first and second face of the disk within the housing, the pressure on the first face being higher than the pressure on the second face to urge seeds against the first face of the disk. A plurality of seeds are distributed against the first face of the disk, whereby the pressure differential substantially urges a single seed into a single hole on the disk. A device is provided for releasing the single seeds from the holes on the disk at substantially the same location for sequential distribution of seeds. The plate has a protrusion to interrupt each of the holes, the protrusion having at least a portion thereof substantially in the plane of the intersection between the first face and the holes for preventing seeds to be retained within the holes to promote unimpeded release of the seeds, the area of the protrusion within the plane being selected to permit the maintenance of a pressure differential between the first and second faces of the plate.

Title: Adaptateur pour installation de materiel au bas de murs
Inventor: TAILLY RICHARD
IPC: E04F19/04
Filed: 2009-02-25
Abstract: Un adaptateur qui peut être installé sur un outil électrique pour faciliter le travail d'installation de plinthes, de bandes de tapis ou autre matériaux similaires au bas de murs. L'outil électrique, lorsque activé, transmet un mouvement orbital et/ou latéral à un support de rouleaux qui exerce alors une pression sur une bande de revêtement sur le mur et frappe sur celle-ci par des mouvements répétitifs et constant. Une plaque de base sert à porter l'assemblage des parties oscillantes et l'outil électrique lui-même. La plaque de base est conçue de façon à exercer une pression constante sur la surface totale de la bande et au bas de la bande à coller. En même temps, à cause d'un léger mouvement latéral créé  par la réciprocité provenant de la partie oscillante de l'outil, une pression supplémentaire est exercée tout au bas de la bande afin d'obtenir une meilleur adhésion de cette région.

IPC: C01B3/34
Filed: 2007-07-17
Abstract: A method for controlling the synthesis gas composition obtained from a steam methane reformer (SMR) that obtains its feedstock as product gas directly from a steam hydro-gasification reactor SHR). The method allows control of the H2/CO syngas ratio by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR. The steam and methane rich product gas of the SHR is generated by means of hydro-gasification of a slurry of carbonaceous material and water. The mass percentages of the product stream at each stage of the process are calculated using a modeling program, such as the ASPEN PLUS~ equilibrium process. By varying the parameters of solid to water ratio and hydrogen to carbon ratio, a sensitivity analysis can be performed that enables one determine the optimum composition of the slurry feedstock to the SHR to obtain a desired syngas ratio output of the SMR. Thus one can adjust the hydrogen feed and the water content of feedstock into the SHR that supplies the SMR to determine the syngas ratio output of the SMR.

IPC: E04F19/00
Filed: 2009-09-14
Abstract: Bulk Eaze is a new invention to facilitate the building of residential and commercial construction. Bulk Eaze is the premanufacturing of boxes and bulk heads. Bulk heads is a construction term to explain any wooden structure in a home used to hide undesirable elements such as, heating and air conditioning duct work, plumbing stacks, electrical wiring, load bearing steel, load bearing materials such as peralam beams, LVL's, 2x8 or larger wooden supports for the purpose of bearing the weight of a structure, as well as add a desireable finish such as coffered ceilings. My products would help save the construction industry days of labor on every house using the product. The bulkheads for finish work would come complete with pot lights and all wiring harness's included. The product would also come pre drywalled and primed with holes predrilled on 16 inch centers to facilitate installation. This would turn what used to be a week or more of work into one day. The product would be sold in 6, 8, 10, 12 or 16 foot lengths with excess material on either end to help in fitting all size rooms. The pot lights are centered in the construction of Bulk Eaze so they always fall centered in the room. Bulk Eaze will be constructed from fingerjoint pine material in a 2x3 format for durability and to meet all building code standards. The term boxes is also used to describe a bulk head. Much the same way a premade roofing truss has eliminated the need for most hand cut roofing applications, Bulk Eaze will remove the cost and need for much of the labor involved in finishing the house framing.
