Title: Process for producing carbon black and valuable by-product gases
IPC: C09C1/50
Filed: 1950-06-01
Abstract: In the production of carbon black by the thermal decomposition of hydrocarbons where an oxygen containing gas and a fuel or carbon monoxide are burned to provide heat for the decomposition, the oxygen containing gas is a mixture of pure oxygen and from 3.9 to 6.3 volumes of a heat absorbing gas such as carbon dioxide, carbon monoxide, water vapour or hydrogen per volume of oxygen. Nitrogen is substantially excluded and the resulting gaseous products after separation of the carbon black, and consisting mainly of carbon monoxide, hydrogen and carbon dioxide are suitable for synthesis processes, the carbon dioxide being removed by washing with triethanolamine; they may also be recycled to provide fuel for the thermal decomposition.  If hydrogen or carbon monoxide is employed both as the fuel and the heat absorbing gas, sufficient is present to react completely with the oxygen, plus an excess which constitutes the heat absorbing gas.  A temperature of 1200 DEG  to 1900 DEG C is preferably maintained in the reaction zone. Before separation of the carbon black cooling may be effected by the injection of water or by natural radiation, but preferably by the injection of cooled heat absorbing gases such as hydrogen, carbon monoxide, carbon dioxide, water vapour or a mixture thereof such as the cooled combustion products recovered in the process.  Specification 672,074 is referred to in this connection.

Abstract: 1,218,112. Automatic control of aircraft. SPERRY RAND CORP. March 22, 1968 [March 30, 1967], No.13901/68. Heading G3R. In an aircraft automatic pilot in which signals from attitude gyros are combined with command signals to control servomotors operating control surfaces, a servomotor is rendered ineffective to operate the control surface if:- (a) high frequency components of any mismatch between signals from the associated attitude gyro and a duplicate gyro persist for a predetermined time interval, or (b) a mismatch between associated gyro, command and servomotor output signals persists for a predetermined time interval which is longer than that at (a) above. As described, application is to the roll channel of an automatic pilot in which a roll attitude gyro, a compass and a radio course receiver combine to control a command servomotor producing signals which are combined with signals from a roll rate gyro to control the aileron servomotor. The servos have positional and rate follow -up and the system involves differential and integral components of control and signal limiting. An electromagnetic relay operated by a delay unit disengages an electromagnetic clutch to disconnect the aileron servomotor drive if high frequency components of mismatch persist for longer than a predetermined time interval between: - (a) signals from the roll attitude gyro and signals from the duplicate gyro. (b) signals from the roll rate gyro and differentiated signals from the roll attitude gyro. (c) integrated roll attitude signals and roll attitude signals applied through a duplicate integrator. (d) signals from the compass and signals from a duplicate compass suitably modified by integrated roll attitude and radio course signals. (e) command signals and command servo output signals. Another electromagnetic relay is operated by a delay unit to disconnect the aileron servomotor drive if mismatch persists for a still longer time interval between:- (a) signals corresponding to a computed rate of operation of the command servomotor and signals corresponding to its actual rate of operation. (b) signals corresponding to a computed rate of operation of the aileron servomotor and signals corresponding to its actual rate of operation. A third electromagnetic relay is operated to disconnect the aileron servomotor drive if the roll command signal exceeds a predetermined value.

Title: Stabilized organic compositions
IPC: C10M133/12
Filed: 1967-03-28
Abstract: Antioxidants for lubricating oils and greases are compositions obtained by oxidatively polymerizing compounds of formula <FORM:1117714/C4-C5/1> or their mixtures with a diphenylamine, wherein Ar is optionally substituted Ph or C10H7, R and R1 are C1- 20 alkyl, aralkyl, aryl, alkaryl, alkoxy or aroxy, and m and n are 0 or an integer. The antioxidants are mixtures containing dimers (e.g. hydrazines or diamines), trimers and -in some cases-dinaphthylamine. Base fluids may be hydrocarbon mineral oils, olefins, polyolefins, polyethers, polyacetals, poly (alkylene oxides), silicones and esters, e.g. di(2-ethylhexyl) sebacate and esters of pentaerythritol (such as the pelargonate/valerate) and of trimethylolpropane.ALSO:The invention relates to compositions which are obtained by oxidatively polymerizing (e.g. dimerizing and trimerizing) compounds of formula <FORM:1117714/C2/1> or their mixtures with a diphenylamine, wherein Ar is optionally substituted Ph or C10H7, R and R1 are C1-20 alkyl, aralkyl, aryl, alkaryl, alkoxy or aroxy, and m and n are 0 or any interger up to the maximum available positions on the aromatic nuclei without hindering formation of the desired product.  Suitable oxidizing agents are air, O2, KMnO4, PbO2, MnO2, H2O2, alkyl and aryl peroxides, and per acids. Examples describe the oxidation of 1-PhNH C10H7 (I), 2-PhNHC10H7 (II) and a II-Ph2NH mixture; the compound (2-PhNHC10 H6-1-)2 is isolated from the oxidation of II. In general, the Specification suggests that the dimers may be hydrazines (coupling through 2 N atoms) or diamines (coupling through 1 N atom and 1 nucleus, or 2 nuclei). (C10H7)2NH is mentioned as a constituent of the product from I.  The above compositions may be used as antioxidants for esters, e.g. di-(2-ethylhexyl) sebacate and pentaerythritol pelargonate-valerate.

Abstract: 1,255,226. Control systems for D.C. motors driving vehicles. M. N. YARDNEY. 18 March, 1969, No. 14117/69. Headings H2H and H2J. A vehicle propulsion system comprising a prime mover, an electric motor and an electric battery is provided with means whereby when the vehicle is moving at a speed below a preset speed the electric motor, which drives the vehicle, is supplied by the battery and when the speed of the vehicle is above the preset speed the driving motor is supplied by a generator driven by the prime mover. A D.C. motor 10 driving a vehicle by way of ashaft 12 is supplied from D.C. supply lines 25, 26 over a pulse width modulator 14, the motor speed being controlled by a control pedal 48 which varies a signal from a potentiometer 58 to the modulator 14 whereby the pulse width is varied to alter the level of the output voltage 16, 18 fed to the motor 10. A tachogenerator 42 provides a signal, representing the vehicle speed to an amplifier 40 wherein it is compared with a preset signal obtained from a potentiometer 44 which signal presets the speed at which the motor supply changes from a battery 22 to an alternator 24 driven by an I.C. engine 30, the alternator output being rectified and supplied to the pulse width modulator 14. When the speed of the vehicle reaches the transition point the signal from the tachogenerator 42 causes the amplifier to produce zero output thus de-energizing relay 36 and closing contact 38. Closure of contact 38 energizes a starter 32 to start the engine 30 whereupon the output of the alternator/rectifier device 24, 23 supplies the motor 10 and also charges the battery 22. Should the vehicle speed drop below the preset value the amplifier 40 produces an output to energize relay 36 thus opening the contact 38 whereupon the engine 30 is stopped and the supply to the motor 10 reverts to the battery 22. The control pedal 48 controls the speed of the engine 30 as well as the width of the pulses produced by the modulator 14. In a second embodiment a governor may be arranged to control the change over from battery to alternator and vice-versa.

Title: Improvements relating to information storage devices
Inventor: GRIBBLE MAURICE WOOLMER
IPC: H03K5/159
Filed: 1965-04-05
Abstract: 1,117,361. Data storage arrangement. FERRANTI Ltd. 4 April, 1966 [5 April, 1965], No. 14298/65. Heading G4C. A plurality of storage delay lines operate in parallel. As shown, a digital data storage device comprises twelve electromagnetic delay lines SDL1 . . . SDL12 each in the form of a printed strip transmission line and each able to store 16 binary bits, the arrangement being such that twelve bit words may be written and non- destructively read in parallel at selected ones of the sixteen addresses. In the idle state, regeneration of data pulses at the ends of the delay lines is effected by tunnel diodes TD1 . . . TD24 to which clock pulses from clock 10 are also applied. Address control means.-Clock pulses are applied by way of a divider circuit 38 to a pulse generator 37 feeding pulses to a delay line ADL21 having a delay length twice that of the lines SDL1-SDL12. A desired one of the sixteen addresses is selected by energizing a corresponding one ofthe inputs A1-A16 to AND-gates 41- 56 whereby a pulse arrives at amplifier 57 at a time corresponding to the selected address. Writing.-When both an address input A1-A16 and the WRITE input are energized together, AND-gate 58 opens to set flip-flop 61 and, after a delay provided by delay line ADL22 (to allow flip-flop 61 to be fully set), AND-gate 62 opens to energize write/inhibit pulse generator 64. A pulse is issued therefrom to each of tunnel-diodes TD13-TD24 in coincidence with a clock pulse to prevent regeneration of the contents of the selected address whereby said address is cleared. After a delay provided by delay line ADL23 and equal to the time for data to travel the length of delay lines SDL1- SDL12, a write pulse is supplied to open each of AND-gates 11-22 whereby the new information is written by tunnel-diodes TD1-TD12 into the selected address. Reading.-If only an address input A1-16 is energized the AND-gate 59 is opened instead of gate 58, flip-flop 61 is reset and AND-gate 63 is opened to energize the read pulse generator 65. The pulse therefrom opens AND-gates 23-34 to allow the selected address to be read into previously reset staticizer 35 from where it may be read out in serial or parallel mode. The timing of the write and address pulses is not critical. In a modified address control means (Fig. 4, not shown) the use of two delay lines ADL21 and ADL24 enables the number of AND-gates associated therewith to be reduced to eight. In a further modified address selecting arrangement (Fig. 5, not shown) the use of a pulse generator 37 which issues both positive and negative pulses (equally spaced) again enables the number of AND-gates to be reduced and a delay line similar to the storage lines SDL1-SDL12 to be used. Stores of higher capacity than 16 are referred to. The generators 64 and 65 may be provided with a variable phase control to allow for slight delays in circuit components other than delay lines.

Title: Echo-sounding apparatus with stablised narrow beam
Inventor: HOPKIN PETER ROY
IPC: G10K11/34
Filed: 1963-04-10
Abstract: 1,038,062. Echo-sounding apparatus. SMITHS INDUSTRIES Ltd. July 9, 1964 [April 10, 1963], No. 14398/63. Heading H4D. In a ship-borne echo-sounder employing crossed fan-shaped transmission and reception beams, either beam may be steered electronically to compensate for roll of the ship. Transducers 10 are mounted in a horizontal row to give a fanshaped reception pattern and are connected through amplifiers 12 to respective magnetic recording heads 13 (Fig. 2, not shown) arranged in a unit 14. Signals received by the transducers 10 are recorded as separate channels on a rotating magnetic drum 15, combined by a replay head 16 common to all the channels, then fed through an amplifier 18 to a display 19 whose time-base is triggered by a generator 20 controlling the transmission of pulses from a transmitting transducer 21. If the row of transducers 10 becomes inclined to the horizontal due to roll or pitch of the ship, echo signals from a point vertically below the ship will arrive with different phases at the different transducers 10. A vertical reference device such as a damped pendulum 23 is used to tilt the recording head unit 14, and preferably the replay head 16 as well, thereby varying the relative distances of the different recording heads 13 from the replay head 16 (as measured around the circumference of drum 15) to provide time delays which compensate for the phase differences between signals at the transducers 10. Similar apparatus may be used to steer a transmittted beam, the pulse signal to be transmitted being recorded simultaneously on several channels and reproduced by separate replay heads connected to respective transmitting transducers arranged in a row. The same magnetic drum and heads may be used for steering both the transmitted and received beam, but with a constant direction of rotation of the drum 15 it is necessary to reverse the order in which the transducers in the row are connected to their respective heads, the switching being effected electrically in the time between transmission of a pulse and reception of the echo signal. The magnetic recording system may also be used to delay fish echo signals relative to sea-bed echo signals for producing a display locked to the sea-bed echo, as described in Specification 785,001. In a modification, the replay head 16 may be replaced by a number of separate heads for the different signal channels, the head outputs being combined electrically for replay, or the heads being fed with the same input signal when used as a recording unit for steering a transmitted beam.

Abstract: b -Anilinovinyl derivatives of heterocyclic nitrogen compounds are produced by condensing a compound of the general formula R1N = CH-OR2, wherein R1 is a phenyl or substituted phenyl group and R2 is an alkyl group, with a quaternary salt of a heterocyclic nitrogen compound having a methyl group attached to the carbon atom in the 2- or 4-position to the quaternary nitrogen or methyl groups attached to both of the carbon atoms by heating them together in absence of a condensing agent and under non-acid conditions.  The reagents may be used together or heated in an inert liquid such as an alcohol. With quaternary salts having a highly reactive methyl group, condensation is effected in a low boiling neutral solvent or by fusion at a temperature less than 100 DEG  C.; with quaternary salts having methyl groups of lower reactivity refluxing in a high boiling solvent or by fusion at a higher temperature.  The preparation of b -anilinovinyl derivatives of pyridinium salts requires a higher reaction temperature.
