Patent number: 12050166Abstract: A system for sensing the volume and/or viscosity of a slurry (e.g., like concrete) contained in a rotating container or drum, having a sensor and a signal processor. The sensor is configured to attach inside a rotating container or drum having a known geometry, sense angular positions of the sensor and also sense associated entry and exit points when the sensor enters and exits the slurry, including concrete, contained in the rotating container or drum, and provide signaling containing information about the angular positions and the associated entry and exit points.

Patent number: 12005460Abstract: Apparatus uses engineered collection media to recover mineral particles in a mineral extraction process, e.g., for processing a tailings stream at the end of a flotation separation process. The engineered collection media are added to slurry/tailings containing the mineral particles. The engineered collection media have collection surfaces coated with a chemical selected for attracting the mineral particles to the collection surfaces so the engineered collection media becomes mineral laden media in the slurry/tailings in a loading stage. The apparatus include three stages: removing unwanted material from mineral laden media; using a stripping agent to strip the mineral particles from the mineral laden media; and separating the engineered collection media from the mineral particles and the stripping agent. The stripping agent is reused for stripping, and the engineered collection media are returned to the loading stage. The engineered collection media can have a smooth or foam-like surface.Type: GrantFiled: August 29, 2022Date of Patent: June 11, 2024Assignee: CIDRA CORPORATE SERVICES LLCInventors: Paul J.

Patent number: 11752506Abstract: A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.Type: GrantFiled: October 6, 2021Date of Patent: September 12, 2023Assignee: CIDRA CORPORATE SERVICES, INC.Inventors: Mark R.

Patent number: 11440026Abstract: Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.Type: GrantFiled: September 28, 2020Date of Patent: September 13, 2022Assignee: CiDRA Corporate Services LLCInventors: Paul J.

Patent number: 11396905Abstract: The apparatus includes a first tie rod end component having a first threaded surface and a second tie rod end component having a second threaded surface. The first and second tie rod end components are configured to rotatably couple to a center component in opposite directions. The tie rod end components each include a groove designed to assist a user in determining whether the tie rod ends are properly coupled to the center component. If the groove is visible to a user then the tie-rod end is not screwed in far enough. In contrast, it the groove is hidden that indicates that the tie rod end component and the center component are properly assembled to each other.Type: GrantFiled: November 30, 2017Date of Patent: July 26, 2022Assignee: Stemco Products, Inc.Inventors: William Chirrey, Paul Dolan, Altan Ugurkan, James Allen Baker
