Filed: 1918-04-24
Abstract: 125,516. Wielgolaski, F. H. A. April 24, 1918. Gases, trcating with electric discharge. - A double or multiple are is elongated, and shortcircuiting is prevented, by blowing cold reaction gases between the arc limbs from openings arranged over the whole length of the furnace space. The limbs s of the arc may be contained in cylindrical chambers connected by a narrow slot or slots pin which the arc limbs can unite. In a single-phase furnace, cold as may be injected through a row of ducts a situated opposite to a sharp edge k<1> of the slot so that the currents are divided and flow helically upwards in each chamber. In another form, ducts situated on both sides of the slot are inclined so that each row feeds one chamber, the gas rotating in the same direction in both chambers. Fig. 3 shows an analogous arrangement in a 3-phase furnace. In a further modification, the gas ports enter the chambers tangentially nearly opposite to the slot or slots. An auxiliary rod electrode may be placed in the centre of the slot or slots and supported from either end of the furnace, the horn-shaped main electrodes being situated above a gas inlet at the lower end. A watercooled top plate serving as a limit electrode may have separate gas outlets for the cylindrical chambers; or a common central outlet, in which the arcs unite, may be provided. Elongation of the arcs may be assisted by a magnetic field, or .by making the furnace walls conductive or embedding a helical conductor therein.

Title: Improvements in or relating to rotational field radio beacons
IPC: G01S1/02
Filed: 1958-03-05
Abstract: 846,997. Aerials; radio navigation. SVENSKA AKTIEBOLAGET GASACCUMULATOR. March 5, 1958 [Sept. 4, 1957], No. 7062/58. Class 40(7). In a radio beacon which transmits periodically a bearing statement from a directional aerial system rotatable mechanically or electrically and a covering field to prevent erroneous bearings the aerial system is so fed that the azimuthal radiation displacement is zero during a bearing transmission. In one embodiment Figs. 2, 3 the speech-modulated carrier is fed to mechanicallyrotated array 49<SP>1</SP>-54<SP>1</SP> via line 38 and a loop 40 reciprocated in an insulated guide between feeders 41, 42 by wheel 48 which rotates at the product of the aerial speed and the number of bearing statements per 360 degrees. As the aerial rotates during a bearing statement its radiation direction is unchanged due to the counterrotational slewing arising from effective displacement of feed points 38<SP>1</SP>, 38<SP>11</SP> along lines 55, 56. Similar slewing arrangements are made for the complementary covering-field tone emissions. In another embodiment Fig. 8 the bearing signal is fed to rotor elements 105-110 of a commutated rotating-field fixed aerial system (see Specification 846,998). As the elements rotate the near-constant separation between them and aerial feeder stator elements 91-96 as the bearing statement ensues causes the radiation direction to remain fixed.

Abstract: 540,579. Phase-difference measurements. STANDARD TELEPHONES & CABLES, Ltd., and SECKER, B. April 19, 1940, No. 7096. [Class 37] A rectifier bridge RB is connected in series between a D.C. meter DM and a variable resistance network VN, and a source of alternating current A.C. is connected to the bridge so as to vary its resistance in synchronism with the alternating current, the network TN producing the change of phase to be measured being connected between the network VN and the source A.C. A transformer TR is interposed between the network VN and the rectifier bridge RB, the mid-point X of the secondary winding being connected to one terminal of the alternating current source AC, which may be an oscillator. The other terminal of the oscillator AC is connected to a centre tapping Y on the meter DM. The apparatus, with or without the oscillator AC, may be arranged in a single casing having terminals T1, T2 for connection to the network TN to be tested. The network VN is adjusted until its output has a specified constant value. The deflection on the meter DM is proportional to the course of the change in phase produced in the alternating current in its passage through the network TN. If the meter is a sine galvanometer the deflection may be made proportional to the phase change and may be directly calibrated in phase angles. The rectified bridge RB may be formed of static contact rectifiers or, for low frequency measurements, it may be replaced by a mechanically operated change-over switch operating in synchronism with the current fed to the network TN.

Title: Improvements in or relating to styrene fractionation
IPC: C07C15/46
Filed: 1943-05-10
Abstract: <PICT:0590590/III/1> Polymerisable vinyl aromatic compounds, e.g., styrene are recovered from mixtures containing them and nonpolymerisable aromatic compounds a portion of which boil close to and the remainder substantially below the boiling point of the styrene &c., by first distilling the mixture to recover overhead the compounds having substantially lower boiling points and as bottoms the styrene and compounds of similar boiling point and then subjecting the latter to multistage distillation under substantially reduced pressure to recover the styrene without polymerisation thereof.  The mixture may be that obtained when ethyl benzene, produced by alkylating cracked ethylene, is subjected to dehydrogenation to obtain styrene, and which contains benzene, toluene, ethyl benzene, styrene, isopropyl benzene and higher boiling components of complex nature.  The mixture is fed through line 10 and preheater 11 to first distillation column 12 where benzene and toluene with some ethyl benzene are removed overhead to condenser 15 and tank 18.  The bottoms are fed to flash column 22 maintained under vacuum of 50mm. from which high boiling residua are removed through line 46.  The ethyl benzene overhead is further fractionated in column 60 from which ethyl benzene is recovered as overhead while the bottoms comprising a styrene enriched styrene-ethylbenzene mixture are fed to the top of a further column 72 where a bottom fraction further enriched in styrene is obtained, the ethylbenzene overhead being recycled to column 60.  The styrene concentrate from column 72 is subjected to a final fractionation in column 90 to recover overhead substantially pure styrene, higher boiling components being removed as bottoms through line 97.  The benzene-toluene condensate from column 12 is subjected to further fractionation in column 26, 34 to separate benzene and toluene from any ethyl benzene admixed therewith.  The process can also be applied to the styrene fraction recovered from drip oil used in gas manufacture or coal tar distillates produced in the coking of coal and comprising ethyl benzene, pm- and o-xylenes, styrene, propyl benzene, trimethylbenzenes, olefines and paraffins.
