Title: Fluidized bed combustion method utilizing fine and coarse sorbent feed
Inventor: ABDULALLY IQBAL FAZALEABAS
IPC: F23C10/10
Filed: 1992-06-02
Granted: 2003-01-14
Abstract: A fluidized bed combustion method utilizing fine and coarse sorbent feed to control the temperature of a cooling fluid such as water or steam circulating through a fluid flow circuit of a fluidized bed combustor. Fuel particles, such as coal, along with relatively fine and relatively coarse sorbent material, such as limestone, are fed into the furnace section of a fluidized bed reactor.      The fuel is combusted, and a fluidizing gas such as air is introduced into the furnace section. Flue gases arid entrained material pass from the furnace section, and the entrained material is separated from the flue gases. The separated entrained material passes to a recycle heat exchange section and is cooled before being passed to the furnace section. The recycle heat exchange section is provided with heat exchange surfaces which form part of a fluid flow circuit to transfer heat from the separated entrained material to a cooling fluid such as water or steam which is circulating through the circuit. The ratio of fine to coarse sorbent feed is controlled to control the heat transfer from the separated entrained material in the recycle heat exchange section to the cooling fluid, thereby controlling the temperature of the cooling fluid and enabling the temperature of the cooling fluid to be held constant over a range of fluidized bed reactor loads.

Abstract: A microburst precursor detector utilizes a multiplicity of radar beams (1-4) and samples radar returns, in each beam, from meteorological radar signal reflectors and processes (16) the signal returns in a statistical manner to determine average radar reflectivity and to extract doppler signal parameters. These parameters are utilized to determine a second set of parameters; average doppler frequency within each radar beam, doppler spectral spread within each radar beam, and the skewness of the doppler spectrum in each beam. The second set of parameters is processed (18-20) to establish the existence of a microburst, predicted surface impact, time to impact, wind shear surface location and track, and the magnitude of the wind shear.

Abstract: 2133568 9323716 PCTABS00028 During operation of a flight control system in a coupled aiming mode, wherein a fire control system (55) azimuth command and elevation command provide an aircraft attitude reference, a bank angle calculation function (1077) provides a bank angle signal to place the aircraft in a roll angle which results in a substantially coordinated turn. The bank angle signal is determined primarily as a function of an aiming line of sight heading rate for small azimuth commands, and is determined primarily as a function of aircraft heading rate for large azimuth commands. Additionally, the bank angle initially comprises a component as a function of aircraft lateral acceleration for driving aircraft lateral acceleration to zero, and after the aircraft assumes a roll attitude for turn coordination, the bank angle comprises a component as a function of aircraft side slip for driving aircraft side slip to zero.  Automatic turn coordination is disabled if the pilot maneuvers the aircraft to avoid a coordinated turn, and is re-enabled if the pilot maneuvers the aircraft into a coordinated turn attitude. A  rate feedback path (143) is provided during operation in the coupled aiming mode wherein aircraft yaw and pitch rate error signals are respectively replaced by the rate of change of the azimuth command and the elevation command. During operation in the coupled aiming mode, intended pilot commanded maneuvers maintain full authority at all times.

Abstract: An interexchange carrier (IXC) provides different treatment for calls on which it receives an indication that the caller dialed its access code. Calls placed without dialing the access code of the IXC are completed as in the prior art. One such treatment permits a subscriber to supply an IXC with an associated telephone number to which calls to the subscriber's telephone number should be directed when the caller dials the IXC's access code. A call is originated at a telephone (701). The IXC switch recognizes that its access code was dialed and queries its association data base using the called number (703). The association for the called subscriber is located, if there is one (705), enabling retrieval of the stored forwarding telephone number (707). The call is routed to the telephone line indicated by the forwarding telephone number (709) and the process then exits in step 711.
