摘要： A signal processor receives a signal containing information about a sensor that is spirally wrapped at a known pitch or separation down a pipe having a flow; and determines a flow velocity based at least partly on the information contained in the signal received by applying an autocorrelation function that depends on a relationship between the time between a repeating pattern and the known pitch or separation of the spirally wrapped sensor. The signal processor provides a corresponding signal containing information about the flow velocity. The sensor includes a strain sensor, including a piezo-electric polymer strain sensor fabricated from PVDF, and/or two or more equally spaced spirally wound sensors. The determining includes correlating output signals of two or more equally spaced spirally wound sensors to determine a time delay, and determining the flow velocity based on the time delay and the known pitch or separation.

摘要： An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface. The filter, conveyor belt, collection plate and impeller may have a plurality of passage ways or synthetic beads in order to increase the contacting surfaces.

摘要： A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of a synthetic material such as polymer and the synthetic material is functionalized with molecules having a functional group for attracting mineral particles to the surface in a separation process. The synthetic beads can be placed in flotation cell containing a mixture of water, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.

摘要： A digitizing scanner particularly for scanning transparent films such as X-rays provides an improved illuminator for transmitting light through the film. The illuminator defines a line array of a plurality of individually calibrated and controlled LEDs. The LEDs are calibrated by determining their relative points of projection on a CCD camera array. The camera array scans the LEDs and adjusts them individually to produce a predetermined illumination pattern from the group. The adjustment occurs over a plurality of cycles that address cross-talk between LEDs in the array. The camera includes anti-reflection elements to minimize bounce-back of image light and noise suppression circuitry to reduce low-level signal noise. A central processing unit, interconnected with the camera assembly includes a pixel averager to reduce the inherent resolution of the CCD to a desired level and to attenuate further noise. The scanner can include an illuminator for illuminating a scannable opaque bar-code strip and size-measurement circuitry for determining the relative size and location of the scanned image.

摘要： A creep-resistant optical fiber attachment includes an optical fiber 10, having a cladding 12 and a core 14, having a variation region 16 (expanded or recessed) of an outer dimension on of the cladding and a structure, such as a ferrule 30, disposed against least a portion of the variation region 16. The fiber 10 is held in tension against the ferrule and the ferrule 30 has a size and shape that mechanically locks the ferrule 30 to the variation 16, thereby holding the fiber 10 in tension against the ferrule 30 with minimal relative movement (or creep) in at least one axail direction between the fiber 10 and the ferrule 30. The ferrule 30 may be attached to or part of a larger structure, such as a housing. The variation 16 and the ferrule 30 may have various different shapes and sizes. There may also be a buffer layer 18 between the cladding 12 and the ferrule 30 to protect the fiber 10 and/or to help secure the ferrule 30 to the fiber 10 to minimize creep.

摘要： A common optical path interferometric gauge comprises an optical beam that is split into two beams. Both beams are modulated and recombined after introducing an optical path length difference greater than the coherence length of the optical source. The combined beam is guided along a common optical path and is subsequently split into reference and measurement beams. The measurement beam is guided along a measurement optical path that includes a moving workpiece surface. Both beams are recombined after interposing an optical path length difference therebetween so as to reestablish coherence between portions thereof, producing optical interference indicative of the surface movement.
