Abstract: The invention is directed towards methods and compositions for identifying the amount of hydrofluoric acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of hydrofluoric acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of hydrofluoric acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the hydrofluoric acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.

Abstract: A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.

Abstract: A dispensing system and methods employed therein uses optical displacement sensing to control dispensation of one or more products. An optical displacement sensor measures displacement of a load beam supporting a vessel from which the product is to be dispensed. The displacement of the load beam is related to the amount (weight) of the product remaining in the vessel. The system may thus control dispensation of the product based on the optical displacement measurements.

Abstract: The invention provides methods, compositions, and apparatuses for preventing the formation of scale in heap leach process solution distribution systems comprised of piping, spray nozzels, or emitter tubes. Solution distribution system components often become fouled by scale because of local hot spots more prone to form scale than other locations along the systems length. Positioning sensors that detect periods of high temperature stress and adjusting scale control reagent dosage to send the right amount to inhibit hot spot deposition allows for the control of scale without using wasteful excessive amounts of scale control reagents. This can vastly improve scale control performance under high temperature stress conditions while minimizing scale control reagent waste under less severe stress conditions to reduce the total operating cost of running heap leach mining operations which depend upon well-functioning solution distribution systems.
Abstract: The invention provides methods and compositions for measuring the formation of scale within a process system. The method involves measuring changes in the cell fouling as reflected on the refraction index measurements of a liquid medium with a refractometer and determining the scale formation from changes in the cell fouling factor. This allows for a refractometer to determine the formation of scale in locations that otherwise would not be measureable.
