#4720 Whirlpool in a Vat to Separate Gold from Tailings

#4720 Whirlpool in a Vat to Separate Gold from Tailings #4720  Describe a vat that spins up a base of gold tailings into a whirlpool, material being lifted up in the swirl, then lets the material settle out, possibly aided by particular flow mechanics. This is not a centrifuge. Hydrodynamic Vortex Elutriation Vat This apparatus utilizes controlled swirling vortex flow, fluid shear, and gravity-driven hindered settling rather than mechanical centrifugal g-forces (such as those in a Knelson or Falcon concentrator). It operates by converting tangential fluid momentum into a vertical toroidal vortex that stratifies gold tailings by specific gravity and particle diameter. Physical Architecture Vat Geometry: A vertical, flat-bottomed or steep-conical cylindrical vessel (typically with an aspect ratio of 1:1 to 1.5:1 height-to-diameter). The lower section transitions into a conical concentrate sump with an underflow valve, while the top perimeter features a continuous peripheral weir for...

#4719 Online Rent-a-FPOV-Drone Service #4719  Safety and lawful above all. Convenient to use. Long range, long duration. Fail safe. Quiet. Stabilized motion, quality camera with zoom. Online rent-a-FPOV-Drone. Air to begin with. System Architecture & Shared Autonomy Cloud Teleoperation Link: Browser/app client communicates over WebRTC/QUIC protocols across dual-bonded 5G/LTE modems. Sub-150ms glass-to-glass latency ensures responsive pilot feedback. Shared Autonomy Layer: The end user controls trajectory and camera orientation via high-level rate or velocity vectors; onboard flight controllers (e.g., PX4/ArduPilot or proprietary autonomy stacks) handle state estimation, balance, and low-level motor actuation. Onboard Edge AI Obstacle Avoidance: Multi-directional stereo vision and solid-state LiDAR feed local collision avoidance algorithms (e.g., dynamic artificial potential fields) that override user inputs if a minimum standoff distance to obstacles or terrain is violate...
