Title: Solution mining and a crystallizer for use therein
Inventor: HAUGEN HARVEY
IPC: E21B43/22
Filed: 2010-12-13
Granted: 2012-12-11
Abstract: In solution mining, holes are drilled parallel to the ground in the ore body to form a series of zig-zag channels. These holes are connected to respective holes from the surface to provide a feed and delivery path and a solvent is circulated through the system so as to dissolve the ore and carry the ore to the surface. The flow of the solvent through the holes forms circular caverns at the intersection of the horizontal hole as well as meanders by eroding the holes so as to gradually extract the ore on each side of the hole. At the surface the ore is extracted in a series of crystallizers each formed by a vessel with an exterior cooling system and an internal wiping system providing shear inside the vessel. The solvent is topped up, reheated and returned to the paths to continue the process.

Abstract: Redox flow devices are described in which at least one of the positive electrode or negative electrode-active materials is a semi-solid or is a condensed ion-storing electroactive material, and in which at least one of the electrode-active materials is transported to and from an assembly at which the electrochemical reaction occurs, producing electrical energy.  The electronic conductivity of the semi-solid is increased by the addition of conductive particle to suspensions and the surface modification of the solid in semi-solids: coating the solid with a more electron conductive coating material to increase the power of the device. High energy density and high power redox flow devices are disclosed.

Granted: 2017-01-17
Abstract: A current transforming harvester ("CTH") is capable of producing power from a conductor on a preexisting power grid without alteration of the conductor or the preexisting power grid. The CTH includes a current transformer ("CT") that captures energy via magnetic flux from the conductor. The CT is substantially circular and includes two halves called a "split core," which allow the CT to easily attach to the conductor without opening the circuit in which the conductor operates. A clamping mechanism of the CTH may secure the CTH to the conductor via a pair of spring-biased clamp pads. The CTH includes circuitry that converts the magnetic flux energy captured by the CT  into electrical energy suitable for consumption by an electrical device.

Abstract: This invention is related to an ot-toman convertible to a seating unit comprising a back-support assembly, a seat-support assembly, a base frame, and a pair of opposed armrests. Addi-tionally, the ottoman includes a linkage system comprising a plurality of pivotably interconnected linkages, where the linkage system is configured to rotatably couple the seat-support assembly to the back-support assembly, and translatably cou-ple the seat-support assembly and the base frame.  In operation, this furniture piece is moveable be-tween a closed position, resembling an ottoman, and an open position, wherein the back- support assembly forms the backrest of a seating unit ac-cessible to a seated occupant. Specifically, the pivotably interconnected linkages operate such that rearward rotational movement of the back--support assembly induces forward translation of the seat-support assembly in relation to the base frame. This movement coincidentally induces the pair of opposed armrests to raise.

Abstract: A filter cassette (1) for removing particles from an air stream, in particular from a gas stream entering a gas turbine, has an upstream end (14) and a downstream end (16) and comprises a mounting frame to which a filter media (4) is fitted and which has a mounting face (5) adapted for mounting the filter cassette to an opening (15) of a partition (6). The mounting face is positioned between the filter cassette's upstream and downstream ends at a first distance (Dup) from said upstream end (14) and a second distance (Ddown) from said downstream end (16). The first and second distances each amount to more than 10% of an overall length of the filter cassette. Preferably, the mounting face (5) is positioned centrally between the upstream and downstream ends (14, 16), approximately in a barycenter line of the filter cassette (1). The filter cassette thus extends to both sides of the partition opening (15). Filter surface area is increased and torque induced by the filter cassette (1) into the partition (6) is reduced.
