Abstract: <PICT:0665472/III/1> <PICT:0665472/III/2> <PICT:0665472/III/3> A reactor suitable for hydrocarbon cracking operation and for contacting gaseous or vaporous materials in general, with fluidized finely divided solids, particularly catalysts, is provided with a plurality of elongated stripping zones in parallel, each zone containing a flow reducing means adapted to produce a pressure drop of 0.1 to 5 per sq. inch thereacross, whereby the flow of solids through the zones is equalized.  The flow restricting means may comprise an orifice plate 37, Fig. 1, placed at the outlet of each of a plurality of parallel stripping zones 26 provided with baffles 36, or alternatively the orifice may be placed at the entrance of each stripping zone as in Fig. 7, where an annular space surrounding the reaction chamber is split by vertical radial partitions into a number of stripping zones 128 provided with baffles 138, 139.  The flow of solids to the individual zones is restricted by the orifices 135 which provide the necessary pressure drop.  Stripping steam enters through pipes 137 optionally fitted with jets 140 and the wall 129 of the stripping zone extends well above the dense phase bed level 121. In this reactor dual feed pipes 111 for the solid and fluidizing gases are provided and dual cyclone separators 123 separates the entrained solids from the effluent gases; the return pipes 124 are provided with valves 125 and fluidizing steam pipes 126.  Fig. 9 shows a modification where the flow-restricting orifice is formed between the inner wall 161 of the stripping zone and an inclined plate 160, the upper part of which may be extended parallel to the reactor wall to provide a disengaging space with stripper gas outlet above the level 163 of the fluidized bed. According to an example, gas oil is passed in vapour form together with a silica/alumina or silica/magnesia catalyst to a reaction chamber as shown in Fig. 1 at 800-1100 DEG F, the catalyst/oil ratio varying between 5:1 and 30:1 by weight.

Abstract: 1,270,705. Automatic current control. WESTINGHOUSE ELECTRIC CORP. June 19, 1969 [July 3, 1968], No.30990/69. Heading G3R. The RMS value of current through a load is automatically regulated by sensing the load current, squaring the signal so obtained, averaging the squared signal, comparing the averaged signal with a predetermined reference and varying the firing angle of a semi-conductor switch controlling the current in accordance with the comparison. The described embodiments relate to the stabilization of the anode current of an X-ray tube by regulation of the filament current. In Fig. 1 the current of the filament 12 is sensed by a current transformer 6 whose output is passed to a bridge rectifier 20 feeding a squaring amplifier 30 in turn supplying an integrator 40. The D. C. signal from the latter is fed to a summing amplifier 50 also supplied with signals representative of actual and desired anode current, and of the compensation required for variations in anode voltage. The output of the amplifier 50 is combined with a sawtooth waveform in a level detector 60 which controls a blocking oscillator 80 for providing the firing signal to a semi-conductor switch 4 controlling the filament current, the switch 4 comprising a Triac, a single SCR in a diode bridge or a pair of anti-parallel connected SCR's. The sawtooth waveform generator 70 is synchronized with the power supply 2 to the filament and provides a firing signal for each half cycle of the supply at an angle determined by the algebraic sum of the input signals to the amplifier 50. In another embodiment, Fig. 4 (not shown) appropriate ones of the sensing and control components are duplicated to control respective large and small spot filaments for a two-filament X-ray tube. Gates are provided to select the desired filament and control circuit and a multi-vibrator is added to provide a delayed firing pulse to the blocking oscillator in the control circuit of the unused filament, so energizing the latter with an idling current until it is selected. A control system applicable to a one or two filament tube is described, Fig. 5 (not shown). Application of the invention to control a heating element or incandescent light is envisaged.

Abstract: 991,365. Radio direction finding. STANDARD TELEPHONES & CABLES Ltd. Aug. 30, 1961, No. 31222/61. Heading H4D. In a radio direction-finding system, wherein signals received by a first antenna system at successive points on a circumferential path are combined in a signal combining circuit with signals received by a second antenna system, a frequency shift circuit being connected between the combining circuit and one of the antenna systems, the output of the signal combining circuit is detected by an A.M. detector and an F.M. detector in series and the phase of F.M. detector output signal is compared with that of a reference signal having a frequency integrally related to the frequency of connection of the signal combining circuit to anyone of the successive positions of the first antenna system. In the embodiment shown, the first antenna system 1 comprises a dipole 2, driven in a circular path by a motor 3 which also drives a two-phase alternator, generating two 5 c/s. reference signals in quadrature. Received signals from the stationary antenna 12, comprising the second antenna system, are passed into a frequency shift arrangement 13, comprising a 4 kc/s. generator 17, a balanced modulator 14 and a transmission line bridge 15, giving a lower side band output, which is combined with the frequency modulated signal from dipole 2 in a second transmission line bridge 20 and an A.M. detector 22. The resulting 4 k/s. beat frequency signal, frequency modulated at 5 c/s. is passed to the airfield control tower and detected in an F.M. detector 26, one of the 5'c/s. reference signals previously combined with the frequency modulated signal being separated therefrom by filters 24 and 25. The two 5 c/s. reference signals are applied to a sine/cosine potentiometer 31, to produce a variable phase 5 c/s. reference signal in the rotor thereof, for comparison with the 5 c/s. output signal from the F.M. detector 26, in phase difference detector 35, any output therefrom causing a servo 40 to turn the rotor of the potentiometer until a null position is reached, the position of the rotor then giving an indication of the direction of the radiating source. Pairs of buffer amplifier may be used instead of the transmission line bridges. In another embodiment, Fig. 2 (not shown), stationary antenna 12 is replaced by a second rotating dipole 180 degrees from dipole 2. Alternatively, the first antenna system may comprise a number of fixed antennµ arranged in a closed path with means for connecting each of them in succession to the combining circuit.
