Title: Reclaiming of lead in form of high purity lead compound from recovered electrode paste slime of dismissed lead batteries and/or of lead minerals
Inventor: MARTINI FEDERICA
IPC: C22B7/00
Filed: 2009-07-30
Abstract: An all-wet process for reclaiming the lead content of impure electrode paste or slime from discarded lead batteries and/or lead minerals, in form of high purity lead compound, comprises a) suspending the impure lead containing material in a lead sulphate dissolving aqueous solution of a salt belonging to the group composed of the acetates of sodium, potassium and ammonium; b) adding to the suspension sulphuric acid in an amount sufficient to convert all lead oxides to lead sulphate soluble in the acetate salt solution and slowly adding to the suspension either hydrogen peroxide or a sulphite or bubbling sulphurous anhydride through it, in a measure adapted to reduce any lead dioxide to lead oxide converted eventually to soluble lead sulphate by the sulphuric acid; c) separating a limpid acetate salt solution containing dissolved lead sulphate from a solid phase residue including all undissolved compounds and impurities; d) adding to the separated solution of lead sulphate either carbonate or hydroxide of the same cation of the acetate salt of the lead sulphate dissolving solution for precipitating highly pure lead carbonate/oxycarbonate or lead oxide or hydroxide, respectively, while forming sulphate of the cation, soluble in the acetate salt solution; and e) separating the precipitated high purity lead compound from the acetate salt solution now containing also sulphate of the same cation of the acetate salt. The acetate salt solution containing also sulphate of the same cation of the acetate salt separated from the precipitated compound of lead is re-cycled to step a) and the content of sulphate of the same cation in the solution is maintained below saturation limit by continuously or periodically cooling at least a portion of the solution separated from the precipitated lead compound to cause selective crystallization of sulphate salt of the same cation of the acetate salt and removing it as a by-product. Optionally, the separated solid phase comprising insoluble compounds of lead and/or undissolved concretions of lead compounds is treated in hot concentrated hydroxide of the same cation of the selected acetate salt and converting these compounds of lead and/or undissolved concretions of lead compounds to soluble plumbites, and the separated lead containing alkaline liquor may be added to the limpid acetate solution for precipitating all reclaimable lead in form of high purity lead oxide or hydroxide.

IPC: G06F1/32
Filed: 2010-09-23
Abstract: A portable computing device (PCD) can selectively supply power to an accessory during PCD hibernation. In some embodiments, the PCD's default behavior is to disable accessory power output during hibernation, and this default behavior can be overridden in response to a request from a connected accessory. The accessory can use the power supplied during PCD hibernation to detect user input (or other) events and wake the PCD from hibernation in response to a detected event. Some accessories can wake the PCD by emulating accessory detachment and reattachment.

Title: A method for exploring a commercial or non commercial, real or virtually created, building in a three dimensional representation
Inventor: BRUNET MARC-ANDRE
IPC: E04H1/00
Filed: 2012-09-11
Abstract: A method for exploring real life or virtually created commercial or non commercial, 3D building representations generated from an original building model or an approximate sketch of the dimensions of the building. By having the exact or approximate dimensions of a commercial or non commercial, real life or virtually created building, a floor plan is generated for each of the building's floors. The atmosphere in and around the building is created in such a way to give the same impression when navigating through the 3D building that a user would have, walking in the real or virtually created building from which the 3D model has been created. A simulation sequence, frame by frame video sequence, is created replicating a first person' s view point walking through the building while accessing a particular location in the building, or using an object to simulate a third person' s view as walking in the building while showing the pathway to access a particular location in the building. Using a particular starting location inside or outside the building (the starting point), the video sequence being played is determined by the user once he chooses his next destination in the 3D building.

Patent CA-2810919-A1 (CA)
Inventor: GEREMIA IVO ANTONIO
IPC: E21B43/38
Filed: 2011-09-08
Abstract: This invention patent relates to an improvement to an alternating piston pump (40), and more specifically to an improvement to an alternating piston pump (40) used in mechanical pumping systems for extracting oil, with a view to solving the problem of flow interruptions when lifting gas-rich fluid. The improvement proposed is characterized in that the sleeve (41) of the alternating piston pump (40) has at least one cavity (46) along the inner surface (411) thereof. Consequently, during the pumping cycle, gas is transferred from the lower chamber (45) to the part of the sleeve (41) above the piston (42) and oil is transferred from the part of the sleeve (41) above the piston (42) to the lower chamber (45). This solves the problem of flow interruptions when lifting gas-rich fluids in mechanical oil-extraction pumping systems.
