Abstract: 702,771. Extracting titanium. TITAN CO., Inc. April 17, 1951 [May 27, 1950], No. 8913/51. Class 82 (1) A batch method for producing titanium comprises reacting titanium tetrachloride and excess metallic magnesium in a reaction chamber at an elevated temperature, e.g above 712‹C. and below 980‹C., removing molten magnesium chloride produced by the reaction from the chamber during the reaction and, subsequent to the reaction, removing residual magnesium chloride and any unreacted metallic magnesium from the titanium metal by distillation. Titanium tetrachloride may be added continuously to the reaction chamber, e.g. in a gaseous state, and magnesium intermittently. The apparatus shown in Fig. 1 comprises a reaction zone 11 set in a furnace 15 into which magnesium billets 21 are fed through port 20 and titanium tetrachloride vapour through port 19. Reaction products collect on the plate forming the bottom of the reaction zone and molten magnesium chloride drains through the annular aperture 14, the width of which may vary from 0.001-0.125 inch, into a receiving zone 13. Residual magnesium and magnesium chloride are distilled from the titanium product, vacuum being applied to the apparatus through vacuum pump 17, the vapours. condensing in zone 12. In the apparatus shown in Fig. 2 the reaction takes place in a reaction pot 31, zone 13 constituting both the receiving zone and the condensation zone, being directly connected to the vacuum pump 17. During the distillation, vapours of magnesium and magnesium chloride pass over the top edge of the pot, through passageway 33 and into the zone 13.

Abstract: 826,727. Automatic exchange systems. TELEPHONE MANUFACTURING CO. Ltd. Feb. 22, 1956 [March 3, 1955], No. 9447/55. Class 40 (4). [Also in Group XL (c)] In a circuit for repeating either A.C. or D.C. impulses, a triode V1 controlling an impulsing relay P is biased back by the leading edge transient to compensate for the tendency of impulses to be longer when derived from high level signals. Fig. 1 illustrates the relay operating times for low and high level impulses f, #1, x being the operating current of the relay. In one arrangement, Fig. 5, audio-frequency signals from an amplifier VIA are rectified at W to produce a control potential across resistor R. In response only to transients, a transformer TR1 and a half-wave rectifier V1B produce a biasing potential across elements R2, C2, The transient biasing potential across R2, C2 is opposed to the signalling potential across R and has the effect of delaying the operation of relay P. Rectifier V1B may be replaced by a fullwave rectifier so that the release of relay P is accelerated by the trailing edge transient. In relay P polarizing winding w is used to balance the standing anode current of V1. Resistor R1 and capacitor C1 in the grid circuit of V1 are also effective to delay operation of P and advance release of P. The transient bias voltage is adjusted by means of resistor R4 which also controls the polarizing winding w of relay P. The arrangement may be used for " tone-on " signals as well as for " tone-off " signals.

Abstract: Process for loosening the lower and upper regions of the soil for applying fertilisers, as well as for loosening the underground layer of the soil and/or for working the upper layer of the soil, and for applying other additives using digging tools (2, 2', 2'') to break up the soil. The digging edge of the digging tool (2, 2',2'') moves in an ellipse overlying a rectilinear movement, i.e. the direction of motion. The resulting movement of the digging edge is therefore a cycloid. The longest axis of the ellipse goes from the surface of the soil into the soil and is inclined in relation to the direction of motion. The additive, for example a fertilizer, can be blown into the crevice which is formed behind the tool (2).
