Filed: 1964-10-05
Abstract: 1,074,259. Gas/liquid multistage reactor: automatic reaction control. M. BALLESTRA. Oct. 5, 1964 [Oct. 4, 1963; Nov. 5, 1963], No. 40580/64. Headings B1F and B1X. In an apparatus comprising a plurality of reaction chambers (A,B,C) connected for series flow of a liquid reactant/reaction product therethrough, having means to admit reactant gas in parallel to each reaction chamber and a stirrer 3 in each reaction chamber; said chambers are of spheroidal or double frustoconical shape. As shown in Fig. 1, which is described in part in relation to sulphonation or sulphation of organic compounds, liquid reactants are admitted from line 8 to the bottom of the series of chambers and SO; is admitted to each in the region of the stirrer through conduits 15. The SO 3  is supplied via condui 14 from catalytic sulphur burner 13. The chambers are provided with jackets 1, and spirals 2 for heat exchange fluids. As the reactants and products pass out of the last chamber C, device 12 determines the degree of reaction and controls the amount of liquid fed at 8 by controls 21. Further devices 12 between the individual reactors, control the amounts of gas fed through conduits 15 by the regulating means 16. Recycling to chamber A from Chamber C through conduit 17 is controlled by individual regulating means 18. Fig. 2 shows a similar series of chambers A-C of double frustoconical form having generally similar arrangements, and the composite Figure 1, 2 shows how the two systems may be linked by conduit 22 to continue the reaction with further gas admission and partial recycling from the second to the first system. Fig. 3 (not shown) illustrates the application of the invention to a plurality of composite reactors (D,E,F,G) each comprising a group similar to A-C in Figs. 1 and 2. A final reactor (H) is provided to which no gas is admitted, but a controlled amount of liquid reactant is added (from 23) to the proceeding reactor (G) in order to provide exactly the correct quantity of liquid to make up for a corresponding deficiency provided at the first reactor (D). This arrangement avoids delays inherent in the control system when the whole of the calculated amount of liquid is added to the first reactor. If desired, an inert gas may be supplied with the reactant gas. By this means the reactant gas is increasingly diluted as the reaction mixture passes through the apparatus.

Title: Improvements in or relating to Apparatus for Transmitting a Current Signal
Inventor: HURD EDWARD T E III
IPC: G08C19/02
Filed: 1968-09-05
Abstract: 1,195,617. Line transmission systems; transistor amplifying circuits. HONEYWELL Inc. 5 Sept., 1968 [8 Sept., 1967], No. 42310/68. Headings H3T and H4R. [Also in Divisions G1, G3 and H1] A device for signalling to a remote station over a pair of wires derives its power from tappings on a constant current path connected in parallel with the device across the wires which are supplied from the remote station. In the measuring instruments described a constant current of less than 4 milliamps is drawn from the wires and in dependence upon a measured variable such as temperature a further current path between the wires draws further current to make the total current drawn from the remote (recording or indicating) station up to between 4 and 20 milliamps. The measuring instrument may employ a thermocouple, a resistance bulb, or a strain gauge bridge. The thermocouple arrangement shown comprises a measuring bridge 32 producing a potential difference output at terminals 46 and 56, and an insulated gate field effect transistor 58 driven by an oscillator and arranged to pass the output potentials alternately to an amplifier comprising transistors 68, 72, 76 and 80. The output of the amplifier is demodulated by a synchronous demodulator comprising field effect transistors 106 and 108 driven by the oscillator 60. The demodulated signal is smoothed by capacitor 114 and amplified by transistors 116 and 118, transistor 118 controlling the signalling current in the further path. The power for the apparatus is derived from two constant current paths. The current in the first path is controlled by a field effect transistor 16, a series resistor 18 and a feedback path via a temperature compensating diode to the gate electrode of the transistor. A Zener diode 26 derives from this constant current a constant voltage between the power line 6 and an intermediate power line 24. This first constant current path powers the measuring bridge. The second constant current path controlled by a field effect transistor 94 and series resistor 96 co-operates with a second Zener diode 100 to power the amplifier stages via a further intermediate power line 98. A transistor 102 appears as a constant current source to the line 98 and acts as a dynamic isolating component between stages 72 and 76 preventing feedback of disturbances on line 98. The bridge network comprises first and second arms comprising resistors 36 and 38, a third (measuring) arm comprising a resistor 40 and a thermocouple 2, and a fourth (compensating) arm comprising temperature-sensitive resistors 42, 48 and 52 and resistors 44, 50 and 54. The resistors 42, 44, 48 and 50 have a quadratic characteristic similar to that of the measuring characteristic of the thermocouple. The resistors 52 and 54 compensate for temperature variations in the " span " determining resistor 130.

Abstract: 1323117 Fuel injection systems SOC DES PROCEDES MODERNES D'INJECTION 4 Sept 1970 [5 Sept 1969] 42566/70 Heading G1N In an I.C. engine fuel injection control system, at each instant that injection is required, as determined by an engine controlled distributer 2, the injection control signal from a timing element 5 is delayed for a fixed period by a pulse from a monostable multi-vibrator 3, the injection control signal and the pulse being applied to a trigger circuit 8 for the injector power unit 10. The arrangement is such that when a pulse from 3 exists, the device 8 cannot be triggered by an injection control signal, thereby avoiding overlapping of injections. At the end of each pulse from 3, an injection control pulse is applied by the power unit 10 to an injector solenoid, a thyristor distributer 9 being controlled by the distributer 2 to determine which injector solenoid is to be actuated. A further monostable multivibrator 6 may be continuously or optionally, e.g. for fuel enrichment during acceleration, operable to prolong the injection control signal by a fixed duration. As described, Fig.2 (not shown), the timing element 5 is a relaxation oscillator consisting of a programmable uni-junction transistor (33), the injection control signal duration being determined by engine operating parameters such as intake manifold pressure, engine speed, temperature using variable resisters. The values of the resisters may be chosen such that if there exists a minimum pressure in the intake manifold, e.g. when the engine is running down a hill acting as a brake, the injection of fuel is stopped.
