Title: Process for recovering lithium phosphate and lithium sulfate from lithium-bearing silicates
Inventor: NAPIER ANDREW
IPC: C01B25/30
Filed: 2019-05-30
Abstract: A process for recovering lithium phosphate and lithium sulfate from a lithium-bearing silicate is described. The process includes adding from 800 kg/t to 1600 kg/t of sulfuric acid to a slurry of the lithium-bearing silicate and from 40 kg/t to 600 kg/t of a source of fluoride to produce a leach mixture and heating said leach mixture. A lithium-bearing solution is then separated from the leach mixture and its pH is increased sequentially to pH 3.5 to 4, pH 5.5 to 6 then pH 10.5 to 11 to precipitate, respectively, a first, second and third set of impurities therefrom. The first, second and third sets of impurities are separated from the lithium-bearing solution and lime is added to maintain a soluble Ca concentration of at least 30 mg/L. The lithium-bearing solution is then softened by adding a two sequential amounts of phosphate to precipitate fluorapatite and apatite, respectively. A third amount of phosphate is added to produce a lithium phosphate precipitate which is then separated. The separated lithium phosphate precipitate is then digested in sulphuric acid to produce a digestion mixture from which a lithium sulfate precipitate is separated. An alkali metal hydroxide is added to the separated solution to produce an alkali metal phosphate solution and this is recycled for use as phosphate in the process.

Title: Stretch trailer with roller mechanism
Inventor: LUTZ DAVID W
IPC: B60P3/40
Filed: 2020-12-16
Abstract: Stretch trailers had been capable of being adjusted to various lengths but required the user to move a first section of the trailer relative to a second section of the trailer to achieve a predetermined length. Friction forces associated with moving the first section relative to the second section made it difficult to adjust the length of the trailer to a predetermined length. This is addressed by providing a length-adjustable trailer moveable by a cab having a first section with a cavity and a second section positioned with the cavity, where the second section is longitudinally moveable relative to the first section, such that the length of the trailer is variable. The second section has a cart with a wheel that rolls along a floor of the cavity and a height-variable section that co-acts with the wheel. The second section is arranged to move longitudinally relative to the first section by the cart rolling along the floor of the cavity. The height-variable section is configured to compress or decompress based on a load on the trailer.

Filed: 2019-08-13
Abstract: A communication system includes a control wireless station. One or more data payload-conveying wireless stations rely on the control wireless station to provide control information to a mobile communication device to control conveyance of data over one or more data channels to the mobile communication device. For example, to connect to a remote network, a mobile communication device establishes a first wireless communication link with the control wireless station. The mobile communication device establishes a second wireless communication link with a data conveying wireless station. The first wireless link conveys control information from the control wireless station to the mobile communication device. The second wireless link conveys data payload information. The control information conveyed over the first wireless link controls conveyance of the data payload information over the second wireless communication link.
