Title: Improvements in or relating to the solvent extraction of mineral oils
IPC: C10G7/08
Filed: 1945-03-20
Abstract: In the solvent extraction of aromatic hydrocarbons from mineral oils by the countercurrent treatment of petroleum vapour with a selective solvent, the solvent loss in the extractor overhead is reduced by injecting into the top of the extractor a liquid, e.g., water, which is completely or at least partially miscible with the solvent but relatively immiscible with the petroleum fraction being treated.  The injected liquid preferably has a boiling point of from 25 DEG  to 200 DEG F. lower than that of the petroleum fraction, and is recovered with the raffinate from which it is separated and recycled to the treating zone.  The process is applicable to the extraction of toluene from virgin cracked and hydroformed naphthas using solvents such as phenol, methylethyl ketone and methyl alcohol and the extraction of isoprene and n.butylenes from mixtures of saturated and unsaturated hydrocarbons, using acetone as a selective solvent. Referring to the Figure, naphtha vapour is introduced through pipe 4 into the tower 1 provided with perforated plates 2 and a steam coil 3.  Liquid phenol, the selective solvent, is introduced through pipe 5 <PICT:0596399/III/1> and flows countercurrently to the rising naphtha vapour.  Water is introduced through pipe 18 to the top of the tower.  The extract is drawn off by pipe 6 and the petroleum vapours are drawn off through pipe 8 and condensed in condenser 9. The condensate passes to settler 11 where separation of mineral oil from water is effected.  The raffinate oil may be refluxed through the upper part of the tower by passing it through pipe 13.  Water is removed from the settler by pipe 16 and is returned to the upper plates of the tower although it may be introduced on or below the phenol feed plate.  Pipe 18 serves to draw off excess water from or introduce fresh water to the system.  Recovery of solvent from the extracts may also be obtained by feeding the extracts into a distillation column to remove overhead the hydrocarbons, water being injected into the top of the column to obtain efficient recovery of the solvent.

Filed: 1943-05-04
Abstract: 586,714. Electron oscillators ; wireless apparatus. BULL, C. S, May 4, 1943, No. 7063. [Classes 39 (i); 40 (iii) and 40 (v)] Escape of high-frequency energy from a resonator 3, along a conductor 4, is prevented by a further tuned resonator 6, having a reentrant wall so that a small gap is provided adjacent the point of escape of energy. Preferably the effective length of the conductor within the resonator is made a quarter wave-length, or an odd multiple thereof. The tuning of resonators 3, 6 is by movable plungers and is adjusted by trial and error until the escape of energy is a minimum. The application shown is to an electron discharge device of the kind described in Specification 577,173, in which electrons from cathode 1 pass through grid 2 into resonator 3 and are reflected by anode 4, the whole acting as a diode ; a signal frequency and a local oscillation are both fed into resonator 3 and mixing occurs, the intermediate frequency passing out along anode conductor 4, unaffected by resonator 6. In a modification, the resonator 6 is applied to a cathode conductor passing into a resonator, or to the arrangement of Specification 574,009. Further, the arrangemay be used to prevent escape of energy from a screen surrounding high-frequency apparatus. Resonator 6 need not be in contact with the resonator or screen, but may be separated from it by a distance short compared with a quarter wave-length, the conductor being surrounded by a short tube for this distance.

Title: Improvements in or relating to the supervision of electric power supply circuits
IPC: H01C7/04
Filed: 1942-06-02
Abstract: 557,790. Power measurements ; temperaturevariable resistances. STANDARD TELEPHONES & CABLES, Ltd., McWHIRTER, E. M. S., and DUNN, R. H. June 2, 1942, No. 7454. [Class 37] For detecting changes in the load on a power supply system a pair of similar indirectly heated thermistors are arranged with their resistance elements in adjacent arms of a Wheatstone bridge network, their heating coils being supplied with a current proportional to the load current and to the supply voltage respectively. The resistance elements of the thermistors may be of resistance material having a high negative temperature coefficient, for example a mixture of manganese and nickel oxides with or without the addition of other metallic oxides, the mixture being heat treated. An arrangement is shown for detecting abnormal changes in the load on a single-phase A.C. system. A current transformer CT is connected with its two primary windings in series with the mains 1, 2 and a potential transformer PT has its primary winding bridged across them. The secondary windings are connected respectively to the heating coils r1 r2 of two similar thermistors T1, T2, preferably having a negative temperature coefficient. The resistance elements R1, R2 of the thermistors are connected in adjacent arms of a Wheatstone bridge circuit of which the other two arms comprise equal resistances R0. A relay E is connected in one diagonal and a local source S of E.M.F., which may be A.C. or D.C., is connected to the other diagonal points. Adjustable resistances R3, R4 are connected in series with the heaters r1, r2. The relay E may be a neutral relay operating when the load changes either way by a predetermined amount and may operate an alarm or carry out a switching operation. Alternatively it may be a polarized relay operating a different alarm according as the change in the load is an increase or a decrease. The thermistors may have a positive instead of a negative temperature coefficient. Each of the transformers CT, PT may have three primary windings for connection to a three-phase svstem, those of the current transformer CT being connected in series with the mains and those of the potential transformer PT being connected either in star or delta formation.
