Title: Recuperation de cuivre a partir d'une alimentation de procede contenant de l'arsenic
Inventor: BUBAN KELVIN RICHARD
IPC: C22B3/08
Filed: 2016-07-05
Abstract: L'invention concerne un procédé de récupération de cuivre à partir d'une alimentation de procédé comportant un ou plusieurs composants d'alimentation contenant une alimentation sulfidique en un métal de base, du fer, du cuivre et de l'arsenic. L'alimentation de procédé et une solution de trempe aqueuse sont introduites au cours d'une étape de lixiviation oxydative sous pression à une pression partielle d'oxygène supérieure à 200 kPa de façon à former un acide sulfurique libre, à solubiliser le cuivre et un autre métal dans l'alimentation sous la forme de composés de sulfate aqueux et à précipiter l'arsenic sous forme de composés solides de fer et d'arsenic. Une boue traitée comportant une phase liquide contenant de l'acide sulfurique et du sulfate de cuivre et des solides contenant les composés de fer et d'arsenic est retirée et la phase liquide est séparée des solides. Pour réduire la redissolution de l'arsenic et entretenir la stabilité des composés solides de fer et d'arsenic, la température et/ou le niveau d'acide libre et/ou le temps de résidence de la boue traitée sont contrôlés. Le cuivre métallique est recouvert de la phase liquide séparée.

Title: Procedes de traduction sans fil a courte portee et systemes pour validation de tarif de transport mains libres
Inventor: BERGDALE MICAH
IPC: G07C9/02
Filed: 2016-08-04
Abstract: La présente invention porte sur un système et un procédé dans lesquels la technologie Bluetooth est utilisée conjointement avec une application utilisateur sur un dispositif mobile pour faciliter la validation de tarif de transport mains libres au niveau d'une station de transit. L'application utilisateur communique avec un circuit d'attaque de dispositif de commande dans une unité de dispositif de commande qui sert d'interface avec une grille de tarif conforme. Des balises Bluetooth sont utilisées pour déterminer une proximité du passager à la grille et des dispositifs de type caméra déterminent si un passager a pénétré dans une zone de validation de tarif de transport. Un utilisateur muni d'un ticket électronique valide et actif sur son dispositif mobile peut simplement marcher à travers la grille de tarif "mains libres" sans avoir à chercher un ticket physique ou une carte à puce intelligente ou un téléphone mobile. Cette approche mains libres permet d'améliorer considérablement l'expérience de l'utilisateur et le débit de passager à travers des grilles de tarif de transport. Le système de validation de tarif de transport automatisé basé sur Bluetooth détecte également des passagers avec des billets électroniques valides et ceux sans permis de voyage valide.

Patent CA-3011147-A1 (CA)
IPC: A61F13/38
Filed: 2018-07-12
Abstract: The invention is made to remove buildup of wax in the ear drum as the main stream present standard is cotton swab. Cotton swabs use pressure and the roughness of cotton surface to remove the wax build up. This can cause damage to the ear drum and push the ear wax further down the ear canal. The invention allows clean removal of the ear wax with lighter motion and greater amount of ear wax removal. The oblong shape and rounded tip protects the ear drum from damage during use. The oblong shape also allows greater surface area of the ear canal to be in contact with the device during the process. The device is attached to solid core shaft. This shaft allows the device to be held and rotated in a clockwise motion. The device is oblong and several times wider than the shaft rounded at the tip and tapered at the attached point of the shaft. The device is rounded at the tip to allow protection of the ear drum. The solid oblong device has two sections cut out horizontal to the shaft.  These sections are 180 degrees apart from each other. The cut-out section has straight edge and the cavity is extended below the edge. The back surface of the edge has a slight slop to assist material into the cavity below. As the device is rotates the straight edge cuts away the ear wax collected on the surface ear lobe and canal. The rotational motion of this device pushes the cut material into collection cavity.  This invention allows collection of the material and stops the pushing of ear wax up the canal.
