Patent CA-3032938-A1 (CA)
Title: Method for producing smelter-grade alumina from low-grade high-silicon aluminum-containing raw materials
Inventor: SENYUTA ALEKSANDR SERGEEVICH
IPC: C01F7/20
Filed: 2017-09-20
Abstract: The group of inventions relates to metallurgy and can be used in processing low-grade high-silicon aluminum-containing raw materials. Aluminum-containing raw materials are milled and then broken up with hydrochloric acid, which is an acidic recycled mother solution. The chloride pulp that forms is separated into waste siliceous residue and clarified chloride solution. Aluminum chloride hexahydrate is crystallized from the clarified chloride solution. The aluminum chloride hexahydrate is thermally decomposed into aluminum oxide and then calcinated, with raw alumina forming as an intermediate product. The raw alumina is leached out with a recycled alkaline solution, and the resulting aluminate solution is decomposed. The 15% acidic mother liquor is subjected to pyrohydrolysis. The chloride ion concentration in the raw alumina is kept at the level of 0.2-5.0%, and the chloride ion concentration in the recycled alkaline solution is kept at the level of 40-90 g/L. After decomposition, the recycled alkaline solution in an amount of 10-40 mass % of the entire stream is evaporated until crystals of chlorine-containing compounds form, which are removed from the process. The quality of the alumina is improved and the energy expended to produce it is decreased.

Title: Global navigation satellite system (gnss) antenna data link
Inventor: FREESTONE JERRY ALLAN
IPC: G01S19/21
Filed: 2019-04-23
Abstract: An antenna enclosure includes a sensor and a Global Navigation Satellite System (GNSS) antenna. Within the antenna enclosure, sensor data is combined with GNSS  information to produce a RF communication signal, wherein the sensor data is out-of-band from the GNSS information. The RF communication signal is transmitted utilizing a GNSS antenna data link to a receiver side. On the receiver side, the RF  communication signal is split into a GNSS RF path and a sensor RF path. The GNSS signals are transmitted to the GNSS receiver via the GNSS RF path. A sensor RF  communication signal is de-modulated, and the sensor data is transmitted to the GNSS  receiver. When the GNSS antenna data link is bi-directional, information may be transmitted from the GNSS receiver to the antenna enclosure via the GNSS antenna data link.

Inventor: MEDAGLIA AGOSTINO
IPC: F16K31/00
Filed: 2019-06-20
Abstract: A hydraulic stage comprising: a hydraulic element located between and sealing a first and second chamber, wherein the first chamber comprises at least one aperture through which fluid is arranged to flow into or out of the first chamber; and at least one piezoelectric element which is positioned adjacent to the at least one aperture and is arranged to deform in response to an applied potential difference such that it blocks or obstructs the at least one aperture to a varying degree according to the level of deformation, so as to control fluid flow into or out of the first chamber. The level of deformation of the piezoelectric element thus reduces or increases an effective size of the inlet or outlet aperture to which it is adjacent, restricting or permitting an increase in fluid flow accordingly. Generally, the piezoelectric element is arranged to restrict fluid flow into or out of the first chamber when in a neutral position (i.e. when no potential difference is applied) so that deformation away from the aperture reduces the obstructing effect and permits an increase in fluid flow into or out of the first chamber. The deformation of the piezoelectric element can be controlled by changing the potential difference applied to the piezoelectric element, enabling bulky and heavy hydraulic elements to be controlled using a small potential difference without the use of any electronic actuators such as solenoids.

Patent CA-3050820-A1 (CA)
Inventor: GERVAIS JOEL
IPC: A01C7/08
Filed: 2019-07-30
Abstract: Les présents inventeurs ont reconnu quun gradient de pression ou un différentiel de pression dans une ligne de distribution de produit pour transporter un matériau particulaire granulaire, comme des semences ou de lengrais, dans un flux dair vers un champ agricole diminue constamment à mesure que la vitesse de lair dans la ligne de distribution de produit diminue jusquà ce que la vitesse de lair critique soit atteinte. Au-dessous de la vitesse de lair critique, il est possible que le matériau particulaire tombe du flux dair et entraîne un blocage du système. Par conséquent, des capteurs de pression disposés dans la ligne de distribution de produit peuvent être utilisés pour générer un flux dair à une vitesse de fonctionnement optimum qui est supérieure à la vitesse critique mais pourtant inférieure à une vitesse maximale associée à une opération inefficace. Selon un aspect, le flux dair peut être ajusté pour maintenir une vitesse de fonctionnement optimum malgré des changements dans le type de matériau particulaire et/ou le taux auquel le matériau particulaire est mesuré.
