IPC: C01B25/00
Abstract: 1,050,137. Phosphorus pentasulphide. KNAPSACK A.G. March 25, 1964 [March 28, 1963], No. 12609/64. Heading C1A. Phosphorus pentasulphide is produced by reacting phosphorus and sulphur with agitation at temperatures above 300 C. in a process wherein the starting components are added from separate supply vessels, the filling volumes of which are accurately reproducible by means of an overflow, to a reactor in such quantities that the reaction product has a P content of 28À1 to 28À9%, the addition of the starting compounds being regulated in such a manner that the reactor contains an excess of S over the stoichiometric amount until all the S has been added, and the residual P is thereafter added, whereupon the completely emptied supply vessels are again filled with the respective starting compounds and the P 2 S 5  is removed from the reactor and quenched. Liquid S and P are fed to reactor 2 through lines 4 and 5 from overflow vessels 8 and 9 respectively by means of metering pumps 6 and 7. S is fed to vessel 8, which has overflow 13, by conveyer pump 11 from storage container 12, via line 10. Similarly P is fed to vessel 9, which has overflow 17, by pump 15 from container 16, via line 14. P from line 21 is fed to cleaning vessel 19, with agitator 20, and H 2 SO 4  is fed via line 22. P and H 2 SO 4  are discharged via lines 18 and 23 respectively. P 2 S 5  is discharged from reactor 2 via line 24 or overflow 25 to storage vessel 26 and thence by line 27 to revolving plate 28 and further processing. The S may be added first to the reactor, followed by the P, or the S and P may be added simultaneously, the former more rapidly than the latter. Continuous operation is possible by removing P 2 S 5  during reaction by the overflow 25 and by using several storage vessels for S and P. Alternatively, the product is discharged after a time of stay of, say, 1 to 120 minutes after complete addition of the reactants.

Abstract: 1,053,841. Centrifugal classifiers. J. R. BEREND. April 16, 1964 [Jan. 16, 1963], No. 2027/63. Heading B2P. A classifier comprises a hollow casing 10 including a downwardly diverging portion 11  having an upper entrance portion 17 for particles 19 to be classified, a lower collecting region 12 for the classified particles, means for causing the particles to move from the entrance to the collecting region, a vane or vanes 21 for imparting an angular velocity to a fluid, e.g. gas or air fed to an inlet 18, so as to entrain particles having a density lower than or equal to a selected density, a fluid receiver 14, Fig. 1, or 16a, Fig. 2, in the collecting region 12 for receiving the fluid and the entrained particles, and a particle receiver 16, Fig. 1, of 14g, Fig. 2, in the region 12 for receiving particles having a density greater than the selected density. The classifier shown in Fig. 2 is adapted to classify particles leaving dimensions less than 100 microns and may be connected in series with the classifier of Fig. 1 which serves to classify particles having dimensions generally exceeding 100 microns. The fluid fed at 18 may be sucked through the classifier at sonic speed by a pump connected to an outlet duct 13. The degree of classification may be altered by varying the angle of the vanes 21 and/or by raising or lowering the receiver 16 or 16a. The particles 19 are fed from a hopper 20 by gravity or they may be fluid assisted. In Fig. 1 the lighter particles tend to concentrate in the region of highest fluid velocity along the walls of the casing 10 and are entrained by the helically flowing fluid into the region 14 and out through the duct 13 whereas the heavier particles, which are less affected by the fluid vortex, travel axially through the casing to the receiver 16 and collector 22. In Fig. 2, the reverse is the case, the fluid velocity being highest in the axial region of the casing and the heavier particles being centrifugally flung against the walls of the casing. In modifications: (a) the upper portion 11 of the casing of Fig. 1 may be in the form of a de Laval tube; (b) the vanes 21 may be disposed between the walls of entry portion 17 and a central, preferably generally conical, body; (c) the casing 10 may be tilted out of the vertical position, alternative means being provided to replace the effect of gravity; in this case, the duct 13a of Fig. 2 would extend axially and the portion 12 of casing 10 would be provided at its lowest point with a substantially vertical side limb leading to a heavier particle receiver.

Abstract: 1,265,944. Supply circuits for discharge lamps. INTERNATIONAL STANDARD ELECTRIC CORP. 5 May, 1970 [12 May, 1969], No. 21492/70. Heading H2H. A starting and operating circuit for a highpressure arc lamp 15 such as a xenon or mercury arc lamp comprises a first circuit 45, 57-59, 64 for supplying a high starting voltage, a second circuit 18-20 for supplying a first relatively low direct current voltage for operating the lamp, and a number of circuits 34-36 for supplying a corresponding number of direct current voltages respectively progressively higher than the first voltage. The circuits 34- 36 include diodes 40, 42, 43 and are connected to taps of the secondary winding 26 of a transformer 23, the primary winding 24 of which is supplied with alternating current at 400 c/s. via an inverter 25 and a battery 18. To start the lamp a switch 55 is momentarily closed so that the first circuit which includes a spark gap 58 applies a high voltage across the lamp electrodes. On initial ionisation of the lamp and opening switch 55 lamp current flows in the diodes 43 and a resistor 39, the diodes 40, 42 being back biased so that current does not flow in the circuits 34, 35. As the current in the lamp increases, the back bias on the diodes 42 and then on the diodes 40 is removed so that the lamp is supplied by the low voltage of the circuit 35 and then by the relatively lower voltage of the circuit 34. As the lamp current approaches its operating value, the back bias on a diode 20 is removed so that the lamp current is supplied by the source 18 thus causing the coil 62 of a relay 60 to actuate a contact 63 thereby de-energizing the transformer 23.
