Title: Improvements in or relating to process of and apparatus for production of carbon black
IPC: C09C1/50
Filed: 1948-04-24
Abstract: <PICT:0679819/III/1> Carbon black is produced by introducing vaporous hydrocarbons in the form of an axial stream into one end of a generally cylindrical reaction zone having a reduced choke portion the length of which is greater than its mean diameter connected axially downstream, introducing free-oxygen-containing gas into the reaction zone upstream of the choke in the form of a rotating stream enclosing the axial hydrocarbon stream, burning a portion of the hydrocarbon stream with the oxygen to decompose a portion of the hydrocarbon to carbon black, cooling the effluent gases and separating carbon black therefrom.  Gas oil of 16-25 DEG  A.P.I. gravity having a high aromatic and/or naphthenic hydrocarbon content, which may be preheated to 675 DEG F, is injected through pipe 18, with or without air from annular jacket 19, into refractory lined furnace 13 having insulation 12 enclosed in steel shell 14. Air is introduced into combustion section 10 through one or more tangentially directed pipes 22 (2 shown) and forms a helical layer of flame and combustion products along the walls of the combustion section 10 and choke section 11, which prevents carbon deposition. The effluent passes through water jacket cooler 27, water spray 26, atmospheric cooler 28, to separator 29 whence carbon black is removed.  The section 16 may be square-shouldered instead of tapered and additional air ports may be positioned in the choke section. Specifications 621,031 and 679,818 are referred to.

Title: Improvements in and relating to power propelled dirigible vehicles
IPC: A63G25/00
Filed: 1930-04-10
Abstract: 347,460. Driving and steering motor vehicles. HILL, G. J. and BURROW, A. E., 16, Percy Street, Tottenham Court Road, London. April 10, 1930, No. 11420. [Class 79 (ii).] In an electrically propelled amusement vehicle of the kind having a leading steering wheel a and two rear wheels b driven by separate electric motors c the steering mechanism of the leading wheel is connected to switch means adapted when the steering mechanism is turned either way to cut off or reverse the power in the motor driving the wheel on that side towards which the vehicle is turned. In the construction shown the steering shaft carries arms g adapted to operate reversing switches i, j in the armature circuits of the motors c. As the steering shaft is rotated one or other of the switches is first caused to open the corresponding armature circuit and so cut off the power on that side of the vehicle; if a sharper turn is desired, the steering shaft is rotated further, the current in the armature is reversed and the motor is driven in the opposite direction. The vehicle is of the kind running on a metal floor and deriving power from a trolley arm making contact with a live overhead network. The power supply to the motors is controlled by a foot-operated switch h. In a modification the switches are arranged merely to cut off the power supply to their respective motors and do not act as reversing switches.

Title: Improvements in or relating to gyroscopic compasses
IPC: G01C19/40
Filed: 1940-07-16
Abstract: 554,595. Automatic control systems ; gyroscopic apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., GRAHAM, J. ST. C. W., WOODHEAD, H. S., LAWRENCE, C. F., and JORDAN, T. C. July 16, 1940, No. 11747. [Class 38 (iv)] [Also in Groups XX and XXXVIII] A gyroscopic compass is operated entirely from a direct current source, a rotary converter 18, with eight poles and a wave-winding with only two commutator brushes, producing 3- phase alternating current to drive the induction motor rotor. This converter actuates also cams driving switches transmitting current to repeating compasses and means 46 whereby a magnetic compass control is periodically rendered effective. A magnetic compass system 14 with limited N-seeking movement is mounted for rotation about a vertical axis in a frame 13 which carries a horizontally pivoted gyroscope 10 and is also rotatable about the said axis. The frame is oscillated by follower gear comprising a reversible electric motor 20 so as to be maintained aligned with the gyroscope and further follower gear is operated periodically to precess the gyroscope to maintain the frame and magnet system aligned. Rapid alignment is obtained when the current is first applied by a manual switch short-circuiting resistance in series with the coils of pot magnets 15 which are selectively energized according to the relation between magnet system 14 and frame 13 to produce eddy currents in the external rotor of the gyro and cause its precession. In normal operation the precession effect is only sufficient to correct gyro wander. The member 46 is operated by a wire 48 and cams driven by the converter 18 to bring a contact member carried by the magnet system 14 into engagement with one or other of two contacts on the frame 13 connected respectively with the two coils 15. The air gap beween gyro rotor and the pot magnets is variable. The frame is aligned with the gyroscope by continuous oscillation of small amplitude produced by a contact member on the gyro engaging a contact on the frame which energizes a relay to reverse the excitation of the motor 20 normally driving the frame in a direction to close the contacts. A contact 38 frictionally coupled to the frame engages either contact 39 or 40 on a fixed assembly plate 17 to short circuit a resistance in the armature circuit of the motor when the frame is displaced to a predetermined extent and cause rapid alignment of the frame with the gyroscope. Repeating compasses are operated by impulses of direct current simulating 3-phase alternating current and produced by cam actuated switches 34 driven by gearing according to the movements of the frame 13 in relation to the plate 17. The magnet system has an anti-vibration mounting and the framework and pivots of gearing are of duralumin with bearing elements anodized. Specifications 554,594, [Group XX], and 554,596 are referred to.
