Title: Separation of anthracene from carbazole
IPC: C07C7/171
Filed: 1941-04-25
Abstract: 548,877. Purification of anthracene. IMPERIAL CHEMICAL INDUSTRIES, Ltd. (Du Pont de Nemours & Co., E.I.) April 25, 1941, No. 5371. [Class 2 (iii)] Crude anthracene is purified, and in particular separated from admixture with small amounts of carbazole by a process which comprises continuously bringing crude anthracene into solution in a solvent therefor, continuously passing the solution through the body of sulphuric acid of 80-86 per cent. strength which will react with the carbazole to form a salt insoluble in the solvent, the acid being maintained within a temperature range of 20‹-30‹C. at which reaction between it and the anthracene will not take place, and continuously treating the carbazole-free anthracene for separate recovery of anthracene and solvent and continuously returning solvent to the dissolving stage of the process. Solvents mentioned include benzene and mixtures of benzene and hydrogenated benzene formed as a by-product in other chemical processes. Instead of sulphuric acid, anhydrous hydrofluoric acid may be used. In an example, anthracene is placed in dissolver A which is filled with benzene, and benzene is placed in C until it is two-thirds full. The acid scrubber B is charged with 85 per cent. sulphuric acid, until it is almost full and then completely filled with benzene. Vessels A and B are agitated and vessel B is heated to start the distillation. Benzene from C is condensed into A and there maintained at 20‹-30‹C. The anthracene solution thus obtained passes through B which is maintained also at 20‹-30‹C. whereby the carbazole goes into solution in the sulphuric acid and the carbazole-free anthracene passes to C where it accumulates. Carbazole sulphate crystals separate in. B and are drawn off. In cases where there is present a considerable amount of phenanthrene in addition to the anthracene and carbazole, it is preferred to subject the crude material by a preliminary treatment with benzene, by slurrying the crude material with benzene and removing the solvent which contains almost only phenanthrene to a separate still for solvent recovery. The residual solid is then transferred to dissolver A for treatment as above. Specification 27,596/04, [Class 2], is referred to.

Title: A homogeniser
IPC: B01F3/08
Filed: 1960-02-17
Abstract: <PICT:0872842/III/1> The homogenizer is provided with a number of pump chambers 2, each having a suction valve 3, a delivery valve 4 and a plunger 5; all of said chambers being connected to a common supply conduit 6 for the emulsion to be homogenized and all discharge into a common pressure-chamber 9.  The abutting ends of the stationary bored seat 10 and the follower 12 have a reduced external diameter so that oppositely directed thrust faces 13 and 14 are formed in such a manner that when a predetermined pressure in the pressure chamber 9 is reached the follower 12 will axially move away from the seat so that a narrow slit will form between the seat and the follower, through which slit the emulsion will be p  forced.  The pressure in the pressure chamber 9 at which the slit between the seat 10 and the follower 12 will form depends on the pressure by means of which the follower 12 is kept urged against the seat 10.  This is why the follower 12 via a loose coupling member 15 is under the influence of a piston 16 which is mounted in a hydraulic cylinder 17 with an adjustable throttle 23.  The follower 12 is kept rotating in order to make it wear evenly and when the homogenizer is inoperative it is sufficient for removing the follower 12 to axially move the coupling member 15 in opposition to the spring 18 and to subsequently remove said member, whereupon the follower 12 and the seat 11 become accessible.  The direction of flow through the slit in the homogenizing member may be directed radially outwards instead of radially inwards.

Abstract: 1,143,338. Transistor pulse delay circuits; pulse modulation circuits. VYZKUMNY USTAV MATEMATICKYCH STROJU. 5 Feb., 1968, No. 5594/68. Headings H3T and H4L. In a delay circuit, having an input to the base of a transistor T, the collector is connected via a parallel connected inductance L and a resistor R1 to a tunnel diode TD and the junction of the inductance L, resistor R1 and tunnel diode TD form the output of the circuit which is connected to a control current I. As described an input pulse U 1  switches ON the transistor at t 1  and when the current in the inductance L has built up sufficiently the tunnel diode TD switches to its high voltage state to give an output at t 2 . The output pulse ends when the input pulse ends at t 3 . By varying the current I the delay period of the circuit can be varied or modulated. A diode D1 and resistor R2 prevent the transistor and tunnel diode from passing excessive current since the diode D1 becomes reverse biased at the required current value. A further diode D2 and resistor R3 protect the collector-base junction of T due to voltage overswings produced by the inductance L when the transistor T is turned OFF. The diode D2 may alternatively be connected to the supply + U 1 .
