  • Apparatus for toner processing including a variable-orifice non-contact valve
    Patent number: 7191807
    Abstract: An apparatus (10) for handling bulk particulate material (M) includes a reservoir hopper (16) having a gas-permeable liner (42) and a gas inlet (44) connecting the reservoir hopper (16) to a pressurized flow of gas sufficient to fluidize the material (M). A transition and pipe assembly (18) receives a flow of material (M) from the reservoir hopper (16). The transition and pipe assembly (18) has an outer conduit (54), an inner conduit (52), and at least one gas inlet (64). The outer conduit (54) is substantially impervious to gas whereas the inner conduit (52) is permeable to gas. The inner conduit (52) is disposed within and surrounded by the outer conduit (54). The gas inlet (64) connects the outer conduit (54) to a pressurized flow of gas to fluidize the material (M) within the inner conduit (52). A variable orifice non-contact valve (24) controls the flow of material (M) from the transition and pipe assembly (18).
