Title: Method and apparatus for introducing reactant fluids into tube furnaces
IPC: C10G9/20
Filed: 1963-09-30
Abstract: <PICT:1063297/C4-C5/1> In a method intended for use in the cracking of hydrocarbons, for introducing the reactant fluids into a reaction tube 1, the fluids are introduced separately into the inlet end of the tube at a pressure such that the pressure drop across the tube inlet is substantially greater than the pressure drop between the inlet and outlet of the tube.  The delivery pressure may, for example, be at least 1.1 times the pressure under which the reaction is to be effected.  The delivery of the reactants is made at regulated intervals.  An apparatus shown for carrying out the method comprises a conical nozzle 7 at the narrow end of which is an inlet 5 for the liquid hydrocarbons.  The nozzle has a perforated wall and is surrounded by an annular space 8 into which high pressure superheated stream is admitted through an inlet 4.  The stream passes through the perforations into the nozzle where it mixes with the hydrocarbons, the mixture being ejected from the nozzle into the tube 1 which contains a catalyst (unspecified).  The tube 1 comprises an inner tube 13 and an outer tube 14 and the reacting fluids pass upwardly through the inner tube and downwardly between the tubes 13, 14 to an outlet 17.  A proportion of the fluid is drawn by an induction nozzle 16 through ports 15 back into the inner tube and recirculated.  The flow through ports 15 is controlled by a flanged plate member 11 which has ports in its flange 18 corresponding to ports 15 and, by means of handles 19, is rotated on the axis of the tube 1 to align the corresponding ports more or less as necessary to control recirculation flow through the nozzle 16.  In a further form described (Fig. 4, not shown) also incorporating inner and outer tubes 13, 14, a tubular member (24) surrounds and is fixed to the nozzle 7.  The tubular member (24) has ports therein corresponding to the ports 15 in the inner tube 13, the assembly (7, 24) forming a unitary mounting which can be rotated to control recirculation flow through the ports 15 to the nozzle 16.

Abstract: 945,963. Electromechanical systems for transmitting power. R. ADOUTTE, K. SCHNEIDER, and M. BAUMGARTNER. Oct. 15, 1962 [Oct. 20, 1961], No. 38879/62. Headings H2H and H2J. In a power-matching arrangement for a diesel electric traction system, a signal representing the desired diesel power output at any speed automatically controls the " electrics " to first strengthen the generator field and then weaken the motor field. Current balancing for parallel motors and current limiting at starting is provided. As described a signal from a tachometer generator 16 driven by the diesel D is " tailored " by a function-generator 17 to provide the power-reference-signal which is compared at 15 with the generator output as sensed in terms of the voltage across device 21 and the motor current multiplied together at 18. The power error signal is applied to function generators 13, 14 to control rectifiers 2, 8, 12, energizing the generator and motor fields. The function generator 13 allows progressive strengthening of the generator field until a certain level is reached, at which the generator control signal is clamped. The function generator 14 allows no control of the motor field until a certain level of error signal is reached after which there is progressive weakening of the motor fields. Current balancing and limiting.-The currents of the two motor groups measured at 23, 24 are fed to a comparator 25 producing two equal limited amplitude signals of opposite sign, and proportional to the current difference. These signals are applied to control the rectifiers 8, 12 to reduce the current difference. During starting the diesel speed control member 4 also varies the function generator 19 to limit the error signal output from comparator 26, which is used as a reference for comparator 20 and compared with the motor current signal from device 22 which compares the two motor current values, and passes on whichever is the bigger. Overload.-When the diesel injection exceed a reference value, a limiting signal may be applied at 26 to comparator 15.

Abstract: 1,248,941. Automatic train control. INTERELEC, and J.-P. MALON. 15 Aug., 1968 [18 Aug., 1967], No. 39043/68. Heading B7N. [Also in Divisions G3 and G4] Apparatus for providing a signal dependant upon the speed of a vehicle moving along a fixed path comprises means providing gauging signals at points along the path; means providing a reference signal of frequency much greater than the gauging signals; and means for counting the number of periods of the reference signal between successive gauging signals, the counting means issuing a signal indicative of the count therein and being reset to zero at the occurrence of each gauging signal. In an automatic speed control system particularly for underground trains, a counter carried by the train counts clock pulses over predetermined lengths of track, trains being braked, driven or allowed to run on under headway according to whether the count is greater than, less than or equal to a fixed base number. A piloting cable is laid between the rails 10b with straight portions 11 separated by discontinuities 12; the cable carries an A.C. signal. The train carries three pick-up coils R, A, B. Coil R picks up the A.C. signal continuously and feeds it to a Schmitt trigger circuit 103 to generate the clock pulses. The coils A, B feed phase discriminator and shaping circuits to provide a reset pulse every time the coils pass over a discontinuity 12 in the cable. The reset pulses control a gate P which allows decade counters D1-D2 to count the clock pulses from the end of each pulse. During the pulse the counters are read and then reset. The reading is applied through decoders to a programme matrix MP which energizes an appropriate one of a set of memory cores MT 3 -MF 3  corresponding respectively to individual braking or traction steps on a controller (not shown). The speed of the train over particular portions of track (e.g. bends or stations) may be varied by varying the spacing between the discontinuities 12 or by supplying different frequency A.C. signals to that portion of the cable. When it is necessary to alter the speeds of all trains in the system (e.g. during rush hours) the frequency of the signals is changed. In an alternative arrangement, not requiring the cable, the reset pulses may be derived from a generator driven from the wheels of the train, the lengths of track then being all equal to the circumference of a wheel. The speed is controlled by altering the frequency of the A.C. signal which may be obtained from a straight cable along the track or from a clock pulse generator on the train whose frequency is altered by trackside units at suitable points.
