Title: Method and apparatus for handling fluidized solids
IPC: C22B1/10
Filed: 1958-06-03
Abstract: <PICT:0856888/III/1> In a multi-stage fluidised bed reactor in which the material from the last bed is discharged into a vertical stand pipe, the material in the stand pipe is raised to a level exceeding that due to the fluid pressure of the last bed by applying a lower pressure to the top of the stand pipe, by connection to the gas space of the first bed.  By this means the overall height of the plant is reduced.  In a suitable apparatus two beds A, B e.g. of iron ore are fluidised by gas e.g. hydrogen admitted through a pipe 18 at the bottom, and passes through a grid 15 and bed B to a grid 13 and bed A.  The iron ore passes downwards through a pipe 16 to the lower bed and is drawn off into a trapped pipe 22 leading to the stand pipe 23 forming a column C. Fluidising gas is admitted through a pipe 29 and one or more inlets 30, and the surface of the column communicates through a pipe 32 and cyclone 33 to the upper reactor 10. Treated ore passes through a trap 24 to a stripper 25, fed with nitrogen gas. The flow of solids into the stand pipe is controlled by valve 31 operating under pressure head p1, the pressure head of the lower reactor being represented by p2.ALSO:Iron ore is reduced to iron powder with hydrogen in a multi-stage fluidized bed furnace, of the type in which the reduced ore is drawn off from the last bed into a vertical stand pipe, wherein the level of solids in the stand pipe is raised above the level due to the fluid pressure of the last bed by applying a reduced pressure to the top e.g. by connection with the first bed.  By this means the overall height of the plant is substantially reduced.  In an example, the iron ore is fed downwards from a first bed to a second (lower) bed, in counter current with reducing gas pre-heated to 1400 DEG F. to 1600 DEG F., and the reduced product drawn off into the stand pipe where a further supply of reducing gas at 300 DEG F. to 100 DEG F. is admitted.  The iron powder is then fed through a trap to a stripping tower where it is freed from hydrogen by a stream of nitrogen gas.

Title: Transportation system
IPC: G05D13/62
Filed: 1971-05-28
Abstract: 1342988 Automatic train control ALDEN SELF-TRANSIT SYSTEMS CORP 28 May 1971 [1 June 1970] 17835/71 Heading B7N [Also in Divisions G3 and G4] Vehicles 10 running on track 14 are controlled to operate at synchronous speed by digital control pulses generated in control station 18 and applied via trackside line 16 and antennas 20 to control apparatus on the vehicles. Loops in track sections A-I which detect vehicle presence are coupled to the control station and these (F-I) in the headway zone H between vehicles are activated to detect if the zone, which moves with the vehicles, becomes occupied. On each vehicle the digital control pulses are applied to an up-down counter 60 which also receives from unit SPE a pulse train representative of distance travelled by the vehicle. The difference signal is applied to a digital-analogue convertor 64 which supplies a required speed output signal to amplifier 66 which has feedback circuits 70, 72 including differentiating elements which act to oppose any sudden change in signal level. The amplifier output is supplied via low pass filter 80 and amplifier 82 to a comparator 52 in which the signal is compared with a voltage from tachometer 48 representing actual vehicle speed. Any error signal is compared in unit 58 with a signal from potentiometer 44 representing the setting of a pump 36 supplying hydraulic fluid to the vehicle drive motor 34 so that the pump setting can be adjusted via servo-valve 42 to any required change in speed. The unit SPE is driven from the motor output and to ensure that the pulses generated correctly indicate the distance travelled these are applied to an auxiliary counter 88 and compared in register 90 with pulses developed in detector 30 as this passes over track markers 28. Any error is applied to counter 60 from correction register 90. Similarly the digital control pulses are counted in counter 96 and this is periodically gated to apply the count to correction register 102 where it is compared with a fixed number corresponding to the number of pulses which should be generated between gating pulses. Any error is used to modify the count in counter 60.
