Abstract
A particle sorter/dispenser wherein particles that are suspended in a liquid are flowed through a conduit and selectively dispensed through a dispensing orifice. The conduit includes a sensing zone wherein the liquid-suspended particles are interrogated by a sensor. Data from the sensor is received by processing electronics that analyzes the data from the sensor and makes a decision whether or not to dispense a particle. The particle sorter/dispenser further includes a switch that, responsive to a signal from the processing electronics, controls whether or not a given particle is dispensed through the dispensing orifice. The switch has one or two valves that introduce relatively high-pressure liquid into the conduit. The flow streamlines of the high-pressure liquid controls the flow of the relatively low-pressure liquid-suspended particles in the conduit. Particles that are not dispensed are flowed past the dispensing orifice to a recycle reservoir that depends from the downstream end of the conduit.
