Patent number: 11932919Abstract: The present disclosure relates to a metal recovery process comprising a solvent extraction process. In an exemplary embodiment, the solution extraction system comprises a plant with a first and second circuit. A high-grade pregnant leach solution (“HGPLS”) is provided to the first and second circuit, and a low-grade pregnant leach solution (“LGPLS”) is provided to the second circuit. The first circuit produces a rich electrolyte, which can be forwarded to a primary metal recovery, and a low-grade raffinate, which can be forwarded to a secondary metal recovery process. The second circuit produces a rich electrolyte, which can also be forwarded to the primary metal recovery process. The first and second circuits are in fluid communication with each other.Type: GrantFiled: December 29, 2022Date of Patent: March 19, 2024Assignee: FREEPORT MINERALS CORPORATIONInventors: Jason M Morgan, Barbara J Savage, David G Meadows, Wayne W Hazen

Patent number: 9726844Abstract: In one aspect, a lighted tip for attachment to a flexible rod comprises a tip body having proximal and distal ends, a mechanical connector at the proximal end, a lens connected to the distal end, a light source that emits light through the lens, and a holder coupled to the light source and the lens. A circuit is completed or interrupted as the holder moves in relation to the tip body, thereby switching the light source on or off. In another aspect, a lighted tip for attachment to a flexible rod comprises a lens forming a distal end of the lighted tip. The lens is cylindrical over at least some of its length, and the tip further includes a light source at least partially within the cylindrical lens portion and a mechanical connector at a proximal end if the lighted tip, for connecting the tip to the flexible rod.Type: GrantFiled: February 12, 2015Date of Patent: August 8, 2017Assignee: Labor Saving Devices, Inc.Inventors: James Forthman, David G.

Patent number: 8324064Abstract: Methods are disclosed for forming an improved varactor diode having first and second terminals. The methods include providing a substrate having a first surface in which are formed isolation regions separating first and second parts of the diode. A varactor junction is formed in the first part with a first side coupled to the first terminal and a second side coupled to the second terminal via a sub-isolation buried layer (SIBL) region extending under the bottom and partly up the sides of the isolation regions to a further doped region that is ohmically connected to the second terminal. The first part does not extend to the SIBL region. The varactor junction desirably comprises a hyper-abrupt doped region. The combination provides improved tuning ratio, operating frequency and breakdown voltage of the varactor diode while still providing adequate Q.Type: GrantFiled: September 30, 2011Date of Patent: December 4, 2012Assignee: Freescale Semiconductors, Inc.Inventors: Pamela J.

Patent number: 6225674Abstract: A semiconductor structure (10) having device isolation structures (43, 44) and shielding structures (39, 40). The shielding structures (39, 40) are formed in a semiconductor material (11) and the device isolation structures (43, 44) are formed within the corresponding shielding structures (39, 40). A noise generating device is formed within a first shielding structure (43) and a noise sensitive device is formed within a second shielding structure (44). The two shielding structures (39, 40) are grounded and prevent noise from the noise generating device from interfering with the noise sensitive device.Type: GrantFiled: April 2, 1999Date of Patent: May 1, 2001Assignee: Motorola, Inc.Inventors: Ik-Sung Lim, David G.
