Patent GB-722869-A (GB)
Title: Improvements in carbon black
IPC: C09C1/50
Filed: 1952-11-17
Abstract: Carbon black is produced by spraying a liquid hydrocarbon upwardly into a zone of a vertically elongated chamber which is subjected to intense radiant heating by means of fuel gases burning within said chamber, about the periphery of the zone of intense radiant heating in the presence of a free oxygen-containing gas, thereby highly heating, vaporizing and pyrolyzing said hydrocarbons within said zone substantially solely by radiant heating, without substantial combustion thereof and while out of contact with flaming gases or solid surfaces, effecting partial combustion of the hydrocarbons of the spray within a zone of the chamber immediately above the zone of intense radiant heating to form a canopy of highly luminous flame radiating further heat to the first said zone, and thereby decomposing the hydrocarbons in the zone of partial combustion to form carbon black in suspension in the furnace gases, withdrawing the suspension from the upper end of the furnace chamber and separating the suspended carbon.  The liquid hydrocarbon may be sprayed upwardly with an initial velocity of 500 to 1400, preferably 800 ft. per. sec. if desired by the use of a two-fluid nozzle with steam.  The zone of intense radiant heating may be heated by a multiplicity of flames or said burning fuel gas, e.g. natural gas, alone, enriched or diluted with steam, preferably preheated by passage through vertical burners in the lower part of said zone to a temperature of 1400 to 2400 DEG F.  The air for combustion is also preferably preheated.  It is preferred to use a heavy petroleum residue having a Saybolt Furol Viscosity not exceeding 100 secs. at 160 DEG F., preferably an aromatic residue resulting from the thermal cracking of the recycle stock from the catalytic cracking of petroleum, which may also be preheated to decrease the viscosity.  The fuel gases may be burnt at the tips of the burners, or the velocities of air and gas may be so arranged that the visible portion of the peripheral flames extends only a short distance below the canopy of luminous flame. The distance between the spray and the canopy may be 1 1/2 to 2 feet.  An Example with full details is given.  Specification 655,799 is referred to, and the apparatus illustrated and described is of the same type but having burners arranged about the periphery of the furnace chamber in the centre of which and preferably slightly below or flush with a horizontal slab of furnace refractory, is positioned the spray from which the oil emerges, preferably at a small initial angle of spread, e.g. 5 degrees.  The carbon produced is stated to have more pronounced "structure" characteristics than that produced by the process of the above Specification.

Title: Emergency signals radio receiver
IPC: H04B1/08
Filed: 1939-11-02
Abstract: 535,106. Wireless signalling. WALKER, W. A. H. Nov. 2, 1939, No. 29209. [Class 40 (v)] A radio receiver comprises a normal receiving channel and an emergency receiving channel tuned to to a pre-determined wavelength, the arrangement being such that when a signal is received on the emergency wavelength the normal channel is rendered inoperative. The normal channel comprises the H.F. amplifier V1, frequency changer V2 and I.F. amplifier V3 the output from which passes to further I.F. and A.F. stages not shown. The emergency channel comprises the corresponding H.F., F.C., and I.F. stages V4, V5, V6, the output from which passes to the same audio-frequency stages. A lead is taken from the grid of V6 to a pair of amplifiers V8, V9 which provide a voltage for V10 which is normally biased to cut-off by the main negative feed-resistance R. The anode feed resistances of V10 are common to the screens of V1 and V2 the point x being connected to the screens of V1 and V2. The arrival of an emergency signal reduces the negative bias of valve V10 so that the increased anode current reduces the voltage on the screens of VI and V2 to render the normal channel inoperative. The emergency signal passes by way of link A, B to the output stages.

Title: Electric oscillators
IPC: H01F17/02
Filed: 1925-11-19
Abstract: 266,428. Wilson, W. H. Nov. 19, 1925. Condensers.-Electric oscillators or oscillatory circuits, applicable to aerial circuits or circuits coupled thereto or thermionic valve circuits or to frame aerials and instruments such as wavemeters, comprise two conductors 1, 2 Fig. 1, wound side bv side into inductance coils with a turn of each interposed, and forming an electrical shield, between neighbouring turns of the other and with remote ends, one of each conductor, connected together directly as at 4 or through a fixed or variable condenser, which may be constituted by the capacity between an aerial and earth, the other remote ends and both pairs of neighbouring ends having no external connection affecting the action of the oscillator. The circuit transmitting energy to the oscillator may be connected across the free ends of the oscillator or across one conductor only or across neighbouring ends of the conductors or across the condenser in the connection 4. The oscillator may be inductively coupled to an aerial circuit, a condenser being connected in the connection 4 and the other ends of the coil being connected to a detector. Each turn of one conductor is in the electric and magnetic field of neighbouring turns of the other giving the affect of a capacity in series with the inductance. The conductors may be round or flat in cross-section with their edges or flat sides adjacent and one or both may be insulated or they may be spaced apart. Multi-layer, helical or flat spiral coils may be used. The remote ends connected together may be the outer ends as in Fig. 1 or the other ends. The double coil may be in two parts 10, 11, Fig. 4, inductively related and relatively rotatable or otherwise adjustable to form a variometer. In an oscillator responding to any one of several frequencies or to a range of frequencies, three or more conductors may be wound together so that one turn of each of the other conductors is interposed between adjacent turns of each conductor, a switch being provided to connect remote ends of any two of the conductors and to interpose a variable condenser if desired and the whole coil being arranged in relatively adjustable parts.

Title: Improvements relating to cross-coil ratio indicating instruments
IPC: G01R27/12
Filed: 1946-10-01
Abstract: 615,597. Electromagnetic ratio measuring instruments. ASHE, T. S., WHITTAKER, J. W., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Oct. 1, 1946, No 29240. [Class 37] A device for overcoming inaccuracies in cross-coil ratio measuring instruments due to the bias produced by ligament torques, consists of a small permanent magnet located in the leakage flux of the magnetic circuit, and secured to the moving coil system so that it exerts a compensating torque opposite and substantially equal to the resultant ligament torque. The compensating magnet 6, secured by a spring clip 7 which is clamped to the coil assembly 9, is magnetized diametrically, and by rotating it in the spring clip 7 the compensating torque can be adjusted from maximum, when the magnetic axis is in line with the leakage flux of the main magnet, to zero, when the magnetic axis of the compensating magnet 6 is at right angles to the main leakage flux, and can therefore be adjusted to suit the leakage flux and ligament torque of any particular instrument. The zero position of the pointer is preferably set to the centre of the meter scale, and the compensating device therefore acts over equal angles on either side of this position. For deflections up to 35 degrees the torque due to the compensating magnet is substantially proportional to the angle of deflection, and therefore proportional to the resultant ligament torque. By adjusting the compensating magnet as described above, these torques can be made equal. The properties required by the compensating magnet are adequately fulfilled by magnets made of the alloy known as Silmanal, described in Specification 535,168, [Group II], which is referred to.

Abstract: 603,897. Cleaners for pipe bowls. EISENRING, T. Nov. 3, 1945, No. 29243. Convention date, Jan. 15. [Class 130] An instrument for cleaning the bowls of tobacco pipes consists of a holding member formed of two plates 1 joined by a crosspiece 2 (Fig. 3), two scrapers 3 hinged to the holding member by means of rivets 4 passing through the slots 5 in the scrapers, and a handle 7 fixed to the holding member by means of the rivet 8 passing through the slot 9. The handle has shoulders 12 and a wedge shaped tip 10 so that on pushing the handle downwards the tip enters the tapered cut-out in the scrapers and pushes them apart to the working position of Fig. 4, i.e. until they fit the pipe bowl. Rotation of the handle then causes the scrapers to remove dirt from the inner surface of the bowl. The bottom parts of the scrapers may overlap (Fig. 7 shows the working position) to provide a continuous scraping edge.
