Title: Fluidized bed discharge process
Inventor: ARONSON ROBERT GEORGE
IPC: B01J4/00
Filed: 1982-07-27
Granted: 1988-05-11
Abstract: Fluidised solid particulate material is conveyed by positive gas transfer from a point in the vessel below the top of the bed and above the distributor plate, using valving.  At a settling zone the solid material is separated from the gas, which is vented back directly and indirectly into the vessel at a point above the point of coveying.  Upon the completion of conveying of the solid particulate material to the settling zone, the valving is actuated to arrest all solid and gas flow to and from the settling zone. The valve associated with the settling zone is actuated to transfer solid particulate material from the settling zone to a transfer zone or convey the gas from one settling zone to a second zone.

Abstract: Internal voltage generation circuit has a good driving power, and maintains a stabilized voltage. The internal voltage generationg circuit includes: a reference voltage generator for applying a reference voltage to an amplifier; an internal voltage generator for having the same structure as that of the reference voltage generator, having a minute-difference voltage as compared with the reference voltage, and having a stabilized output voltage(Out) in a standby state; an amplifier for amplifying a voltage difference between a voltage of the output terminal(OUT) and a reference voltage of the reference voltage generator, and driving MOS transistor(M22); MOS transistor(M22) for providing a large current to an output terminal(OUT), and compensating a voltage drop of the output terminal(OUT); and a bias part for loading a bias to the amplifier.
