Abstract: A TSRU for recovering solvent from solvent diluted tailings includes a separation apparatus receiving the tailings and producing solvent and solvent recovered tailings. The separation apparatus includes a vessel, a tailings outlet, a solvent outlet, a tailings inlet for supplying a variable flow of the tailings to the vessel and a tailings recycle line connected to the tailings inlet for recycling part of the solvent recovered tailings into the variable flow of the diluted tailings to produce a flow rate controlled feed for introduction into the vessel. A tailings solvent recovery process includes separating the diluted tailings into recovered solvent and solvent recovered tailings, discharging the solvent recovered tailings, and recycling a portion of the solvent recovered tailings back into the variable flow of the diluted tailings. A method of controlling feed flow rate to a tailings solvent recovery vessel is also provided.

Abstract: The invention is a two-way generation tidal power plant with bypasses participating in generation. The preferred embodiment of such a tidal power plant has a power house with one-way turbines and additional head and tail reservoirs formed by additional barrages in the basin and the outer bay. The purpose of this invention is to increase the energy production per each tidal cycle and the water volume used for it. The closer this water volume to the water volume filling and emptying the basin under natural conditions without barrage, the smaller is the environmental impact of the tidal power plant. In order to achieve this the main barrage is equipped with bypasses, the sluices passing water during the final phases of the ebb and the flood generations in parallel to the power house turbines and having a discharge capacity up to 1.5 times higher than the discharge capacity of the turbines.

Abstract: The present invention provides a positive electrode active material having a composition of LiFe(P1-XO4) (where P has a mole ratio of 0.910 to 0.999) of chemical formula (1). The positive electrode active material of the present invention has an operating efficiency leveled to the operating efficiency of a negative electrode active material, which is relatively low, and may improve the energy density of the positive electrode active material. Further, as the positive electrode active material, in which the mole ratio (1-x) of phosphorus (P) is adjusted to less than 1, has Fe2+ and Fe3+ coexisting therein, structural collapse caused by the deficiency of phosphorus (P) is prevented, ion conductivity is improved to achieve superior rate capabilities, and IR drop is suppressed during charging/discharging, thus improving energy density.

Abstract: This invention relates to the floating of a body of water, of a pipeline intended to serve as a fresh water duct. This invention outlines the method and the apparatus necessary to float the pipeline under the turbulent ocean waves or between two bodies of water.  Hence, this method reduces the cost drastically, because the pipeline does not rest on the ocean floor and the water moves with less friction.   The invention uses a series of helicoidally-shaped pipe, formed like the cross section of a kidney, wrapped around a large circular ring and uses innovative striations on the inner wall of the pipeline, which creates a natural vortex, thereby minimizing friction.   This invention also relates to using cycloid spiral motion of the fresh water duct, to create energy for a hydropower system for installed twin oval turbines.   The HUG (Helical Unique Generation) system is the nickname given to the Helical Pathway System of the Water Pipeline.

Abstract: A self-contained button attachment kit includes a pair of buttons, fastener clips and a tool for dispensing a fastener from a fastener clip to reattach a button to an article of clothing. The tool includes a single, hollow needle, a holder adapted to retain the needle and buttons, a handle telescopingly mounted on the holder, a spring-biased ejection mechanism connected to the handle, a front cap removably coupled to the handle over the needle and a rear cap removably coupled to the handle for storing fastener clips. In operation, the front cap serves as an anvil that supports the article and button to be attached. With a fastener clip loaded into the holder, the needle is then inserted through the pair of items. Displacement of the handle relative to the holder causes an ejection rod to dispense the cross-bar of a fastener through the needle, thereby completing the attachment process.

Abstract: An intramedullary device for repairing defects of a bone is provided. The intramedullary device is configured to be inserted into the medullary canal of a bone and includes a stud protruding from the end. The stud includes a portion that is tapered from a first cross-sectional area to a second cross-sectional where the second cross-sectional area is smaller than that of the first cross-sectional area and the second cross-sectional area defines a region of concentrated stress. The stud also includes a portion configured to engage the internal threads of a fastener retained within an intramedullary device assembly, such as a guide member adapter. The external threads of the stud engage the internal threads of the fastener to secure the intramedullary device to the intramedullary assembly when a first torque is applied to the fastener. Upon completion of insertion, compression, and securing of the intramedullary device in the medullary canal of a bone, the intramedullary device can be separated from the intramedullary device assembly by applying a second, greater torque to the internally-threaded fastener, whereby the stud breaks at the region of concentrated stress.
