Title: Improvements in or relating to the distillation of benzolised wash oil
Filed: 1953-06-17
Abstract: <PICT:0766120/III/1> In a process for the steam distillation of benzolized wash oil in a fractionating column with return to the head of the column of a portion of the condensed distillate (freed from water), part of the liquid flowing down the upper section of the column is withdrawn therefrom and is heated to at least partial vaporization in an external heater, the vapours from which are passed back into the column at a position above the liquid take-off.  By this means a crude light oil in which the proportion of components boiling below 180 DEG C. amounts to 95 per cent is readily obtained as distillate, without excessive use of live steam.  Benzolized wash oil is supplied through conduit 1, heatexchanger 2 and conduit 3 to heating coil 9 which is disposed in a convection zone of furnace 4. After flowing through coil 9 and also through coil 10, which is in the radiation zone of the furnace, the oil, now at a temperature of about 180 DEG C., passes through reducing valve 11 and conduit 12 into the stripping section of column 13.  Direct steam (12 to 15 kg. per cubic metre of wash oil) is fed to the column through conduit 16. Stripped wash oil is withdrawn from the column through conduit 17. The vapours leaving the head of the column are passed through conduit 18 and heat-exchanger 2 to condenser 19.  The resultant condensate is led to receptacle 21, wherein water separates from light oil.  The water is withdrawn through pipe 22.  Part of the light oil is withdrawn as product through pipe 23, and the remainder is pumped through conduit 26 to the top tray of column 13.  Part of the reflux reaching tray 27 is withdrawn through conduits 28 and 30 to collector 31; it is then pumped through coil 34 which is disposed in a convection zone of furnace 4.  The mixture leaving coil 34 is passed through reducing-valve 35 and conduit 36 into vaporizing chamber 37. Non-vaporized residue is withdrawn from chamber 37 through pipe 38. The vapours from chambers 37 are introduced into the column through conduit 39.  Spent wash oil may be regenerated in the process by introducing it through conduit 40 into collector 31, and withdrawing pitchy residue through pipe 38.

Title: Improvements in or relating to the separation of minerals
IPC: B03D1/012
Filed: 1938-06-08
Abstract: 515,592. Concentrating ores. SMIDTH & CO. AKTIESELSKABET F. L. June 8, 1938, No. 17051. Convention date, Sept. 10, 1937. [Class 82 (ii)] In the froth flotation separation of minerals from carbonaceous ores, i.e. ores which contain graphite or other carbonaceous matter, the flotation of the carbonaceous constituents is prevented or reduced by the addition, as a depressing agent, of a lignum sulphonate such as calcium or sodium lignin sulphonate. The pulp is preferably conditioned with the depressing agent prior to the addition of the collecting and frothing agents. The process is particularly applicable to the concentration of carbonaceous precious metal ores and carbonaceous limestones &c. The usual collecting agents may be used, e.g. xanthates for sulphide minerals, and fatty acids, their mixtures with fuel oil, fatty acid soaps and emulsions, fatty acid and rosin acid mixtures, saponified tall oil, and positive ion agents, for oxidized ores. The concentration of a carbonaceous pyritic gold ore is described, the reagents used being calcium lignin sulphonate and one or more of pine oil, secondary butyl xanthate, copper sulphate, soda ash, and alkyl dithiophosphate. Products suitable for cement manufacture may be obtained by froth flotation of the calcite from a carbonaceous argillaceous limestone, calcium or sodium lignin sulphonate being used in conjunction with oleic acid, a frother consisting of a mixture of branched and straight chain aliphatic monohydric alcohols obtained, together with methanol, by catalytic hydrogenation of carbon oxides, and, in some cases soda ash. In an alternative method the aluminium silicates may be floated from the calcite by using in conjunction with the lignin sulphonate and the frother a positive ion agent, giving in solution a positive ion containing an aliphatic hydrocarbon group of at least 8 carbon atoms, e.g. dodecyl amine hydrochloride or a mixture of the hydrochlorides of the amines in which the alkyl groups correspond to the fatty acids in coconut oil. If desired, the ore pulp may first be subjected to froth flotation without the addition of a depressing agent for the carbonaceous matter, the concentrate containing the carbonaceous matter being then refloated in the presence of a lignin sulphonate. Specifications 515,608 and 515,609 are referred to.

A magnetic transfer system which modulates the transferred signal has a magnetic record driven past a transfer station P, a reproduction means 2 driven past at a selected different velocity and one or more transfer transducers T 2  arranged to produce a transfer enhancing flux normal to the magnetic record 1 and the reproduction means 2. Information recorded on a tape 1 may be copied on to tape 2 and either compressed or expanded. Tape to tape transfer may have the two tapes meeting, as in Fig. 1, or the record 1 may print on to a rotating drum which then reprints on to the reproduction tape (Fig. 2, not shown). Where the tapes or tape and drum are adjacent but moving at different speeds there is preferably a small gap. The drum may act as pressure roller for one tape drive. Alternatively one of the two tapes 60, 62 (Fig. 3) may move intermittently and the tapes are in contact over some length past which the transfer flux head is rotated while the one tape is stationary. Reading drums or tapes.-A signal recorded at 112 (Fig. 3) on a drum 113 is transferred with the aid of a transfer flux inducing head 116 to a drum 115 rotating at a different speed, and then erased by a head EH. Either the drum 115 is read by play-back head 117 or the signal transferred to the tape 2<SP>11</SP>. A tape 82 (Fig. 7, not shown) may be read by moving it intermittently past a drum on to which the signal is transferred and then reading from the drum. Card or strip to tape.-Information on a card C 11  (Fig. 5) is transferred to a tape by holding the card stationary while the tape moves past and moving the transfer flux inducing head TT sideways across the tape, which is then moved on to read the next line of information on the card. Information stored on strips in a magazine S is transferred to a drum 45 (Fig. 4) by selecting the appropriate strip; by positioning the magazine, and winding it through rollers 44 past the transfer station P 1 . Information may be printed from the drum to strips at 46 and the strips returned through the guide 42 to the magazine.

Filed: 1921-06-22
Abstract: 189,165. Breisig, F. June 22, 1921. Inductances, capacities, and time constants of circuits, measuring.-In a method of measuring cross talk between telephone lines, in which the cross talk between substitute lines is compared with that between the actual lines, the substitute lines are given the same alternating current resistance as the actual lines. In an example, Fig. 3, an alternating current source S and a receiver E are connected alternatively to lines I, H and substitute lines a<1>, a<2>, e<1>, e<2>. The condensers C<1>, C<2> with resistances in series with them are arranged to have the same apparent resistance as the lines I, II. Condenser B is adjusted until sounds of equal intensity are heard with either position of the switch U, and its capacity furnishes a measure of the cross talk. The condenser B may have an ohmic resistance in series with it or may be replaced by an ohmic resistance. In a modification, Fig. 4, alternative current resistances R<1>, R<2> shown as condensers, are provided equal m value to the apparent resistar.ces of the lines. The amount of cross talk is furnished by the relative values of the resistances R<13>, R<14>, R<23>, R<24> which may be varied one or more at a time. This arrangement is used in a manner similar to that described in Fig. 3.

Abstract: 134,279. Thornton, T. P. Oct. 25, 1918. Date indicators.-Consists of date-indicating mechanism operated by a watch Fig. 1 is a view of the dial, showing the position of the date readings and of the small watch-movement which controls the corresponding mechanism. Fig. 3 is a rear view of the mechanism, and Fig. 4 is a side view as seen from the left of Fig. 3. The centre arbor of the watch-movement turns once in twelve hours and, through wheels 21, 22 at the rear, gives rotation once in twenty-four hours to a disk 23 bearing a single tooth 24. The main feature of the date mechanism is a large wheel 26 having its pitch-circle divided for as many teeth as a year would have days if every month had thirty-one days, but having the thirty-first tooth for the shorter months omitted, the thirtieth and twenty-ninth being also omitted for February. This wheel is urged to rotate by a going-barrel 44 in gear with a small central wheel 45, and one tooth per day is allowed to escape from a detent 25 by the action thereon of the tooth 24 on the wheel 23. In leap year, an extra tooth is presented to the detent by a tangential wheel 41 geared through the idler 40 to a central wheel 39 one-quarter its size lineally. An annular wheel 46 turning with the large wheel 26 drives a pinion 47 one-twelfth its own size, and therewith the day-of-the-month disk 11 revolves twelve times a year. Once a month, a wheel 48, having teeth 49 corresponding to the last day of the month, gears with an idler 50 and therethrough gives onetwelfth of a revolution to a follower 51 which carries the name-of-the-month disk 13. Once a year, a companion wheel 52 with a few teeth 53 drives the units-of-years disk 17 through an idler 54 and a follower 55. Thence the tens-of-years disk 19 is driven by a carrying wheel 56 which acts on a full wheel 58. A toothed spring barrel 59 gearing into a wheel 60 urges a seven-toothed wheel 61 which is released daily from a detent 64 by the action of a wheel 62 with one tooth on the centre-arbor of the watch-movement. The day-of-the-week disk 15 is thereby operated.
