摘要： Apparatus features an acoustic comb filter module configured to receive signaling containing information about different frequencies F1 and F2 to create a selected comb spacing D to capture certain particles having a selected size X in a flow stream in a flow pipe, and to provide an acoustic standing wave via ultrasonic excitation based at least partly on the two different frequencies F1 and F2 to create the selected comb spacing D to capture the certain particles having the selected size X in the flow stream in the flow pipe. The apparatus may also include a particle size or distribution determination module configured to receive the certain particles for off-stream analysis via a detection port that forms part of the flow pipe and determine the particle size or distribution of the certain particles in the flow stream in the flow pipe.

摘要： A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of or coated with a synthetic material such as a polymer that is naturally hydrophobic or a polymer that is hydrophobically modified. The synthetic bead can be made of glass having a coating or polysiloxane. The synthetic beads can be placed in flotation cell containing a mixture of water, collector molecules, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The collector chemical can be xanthates. 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： An optical sensor formed from an optical waveguide having at least one core surrounded by a cladding and a large diameter generally D-shaped portion is disclosed. Axial or compressive strain across the D-shaped cross section may be determined by measuring the change in polarization or birefringence of the light output from the sensor. A layer responsive to a parameter may be disposed on a flat portion of the D-shaped portion of the sensor. The refractive index of the layer changes and/or the layer applies a strain on the sensor in response to the parameter. Changes in the refractive index of the layer alters the light output from the sensor, which is measured over time and correlated to the parameter.
