Title: Improvements in recovery of titanium tetrachloride
IPC: C22B34/12
Filed: 1958-03-14
Abstract: Titanium tetrachloride is recovered from a gaseous mixture of titanium tetrachloride with at least one of the group ferrous chloride, ferric chloride, and aluminium chloride, by passing the gaseous mixture through a scrubbing chamber in the bottom of which is a slurry of the chlorides in titanium tetrachloride, which is maintained at a temperature close to <PICT:0825273/III/1> <PICT:0825273/III/2> <PICT:0825273/III/3> but below the dew point of the titanium tetrachloride.  A portion of the slurry, without being withdrawn from the chamber, is maintained in violent motion within the chamber, splashing against the sides and thus forming a turbulent shower of the slurry, whereby substantially all the iron and aluminium chlorides are removed from the gaseous mixture without condensing all the titanium tetrachloride.  The purified titanium tetrachloride is recovered as the gaseous effluent from the scrubber. The slurry is preferably maintained at a temperature of 70 DEG  to 80 DEG  C. with a solids content of up to 40%.  Prior to the scubbing, the gaseous mixture may be cooled to condense out some of the impurities.  The purified titanium tetrachloride from the scrubbing process may be condensed in a chamber operating in the same fashion as the scrubbing chamber, employing a liquid titanium tetrachloride shower maintained below 35 DEG  C.  Fig. 1 shows a suitable chamber consisting of a container 5 with a water-jacket 6 to maintain the liquid 11 at the desired temperature, and a rotor 12 dips obliquely into the liquid.  The gaseous mixture enters at 9 and the effluent leaves at 10.  Excess liquid overflows via 18.  Fig. 2 shows another chamber in which the rotor 14 is mounted horizontally, and Fig. 3 shows another chamber in which the liquid is hurled about by a screw 16.  Specification 768,867 is referred to.

The rate of flow of a sample gas is measured indirectly by measuring the difference in flow of a carrier gas e.g. air or nitrogen in two branches D, E, Fig. 1 of a tube A, the sample gas being introduced through part J into branch E downstream of a flow sensitive device I to alter the rate of flow of the carrier gas in that branch by an amount dependant on the rate of flow of the sample gas. The rates of flow of the carrier gas in the two branches are measured by transducers H, I, e. g. thermistors or filaments, as described in Specification 1, 024, 869 or Specification 1, 126, 443 connected in a Wheatstone bridge whose out-ofbalance voltage is indicative of the difference in flow rates. Adjustable flow restrictors K, L are provided in each branch. The mas flow rate of the carrier gas is regulated at B.

Title: Steering system

Abstract: 1,103,693. Differential steering of vehicles. C. B. MESSENGER. 26 Feb., 1965 [2 March, 1964], No. 8492/65. Heading B7H. A vehicle steering system, for use in a wheeled or endless track vehicle with a main engine 13 driving drive components on opposite sides of the vehicle, comprises a control unit 31 including an hydraulic electric or other motor, the rotor 57 and case 56 of which are rotatable in the control unit, and means for interconnecting the rotor and case to respective drive components and means to energize the motor whereby the action-reaction forces of the motor produce differential rotation of the drive components. As shown, track-engaging gears 41, 42 are secured to the casing 56 and the rotor 57 of an hydraulic motor which rotates in bearings 59 in the casing of the control unit 31. Normally, the rotor and casing rotate together but when hydraulic fluid is directed by a steering wheel controlled valve 51 through a line 52 or 53 the rotor and casing rotate at different speeds hence driving the gears 41 and 42 and the tracks at different speeds to steer the vehicle. The endless tracks 26 may be removed and the idler wheels 36 inverted on the chassis cross-member 39 when the vehicle is steered by pivoting the wheels 24 about king- pins. A winding drum or windlass 122 may be attached to the gear 42 and a peg 123 to the gear 41 so that when the hydraulic motor is operated the drum 122 is rotated. In a modification (Fig. 4, not shown), the rear wheels are mounted on stub axles carried by gear casings (104) at the ends of thea xle housing (121) which enclose both a differential gear and a rotatable hydraulic motor (125). Each rear wheel is driven through a gear train (115), (116), (117) in the respective gear casing, the gears (115) being driven from the differential gear and the relative rotation of the intermediate gears being controlled by the motor (125) to steer the vehicle.

A suitable sintering enclosure comprises an upright tube 2 stopped at its ends by a top plate 3 and a bottom plate 4 both of which include hollowed out recesses, 5 and 7, respectively in communication with the body interior and containing the alkali metal carbonate. Tubular blocks of the beta aluminate 1 rest on chocks 11 and the entire assembly is placed in a furnace to effect sintering.

Title: Improvements in the construction of indicating or measuring instruments
IPC: G01R11/04
Filed: 1953-03-27
Abstract: 724,323. Instrument casings. SANGAMO WESTON, Ltd. March 27, 1953 [March 28, 1952], No. 8572/53. Class 106 (4). In a measuring instrument with a cup-like case, a moulded member of resilient material, such as rubber, extending round and in contact with the bottom and inner walls supports the mechanism and co-operates with the transparent cover to form an annular seal. In an electrical instrument, Figs. 4, 9, permanent magnet 28 to which the coil-bearing bridges, scale plate and stops are fixed rests on the block 30 and is bolted to three pillars 32, the lower ends of which are riveted to plate 31 moulded in the block. The whole assembly is thus insulated from shock and electrically insulated from the case. Connections to the coil are made through a pair of rods 35 moulded into the block concentric with and extending through the holes through which the block is extruded. These extrusions being of greater diameter than the holes outside'the case hold the block firmly thereto. The rods have threaded holes running axially from either end, through which the instrument may be flushed out and filled with inert gas and which accommodate screws holding soldering tags 22 and 37. In another embodiment the upper screws are slotted and shortened to give clearance in the holes which are connected with the lower holes allowing the interior to be flushed before final assembly, the lower holes being then sealed off by short screws 66, Fig. 9. The transparent cover 11 is of plate form and has an annular ridge 11<1> which mates with and is sealed to the annular rubber extensions 41 with cement or other known means and rests on the flanged lip 24 of the cup. It is fixed thereto by 6 hollow-headed rivets 45 (see Fig. 6) reduced in diameter where they engage countersunk holes in the flange. The tails of these rivets are spun out into the countersink, thus fixing the cover without straining it, as the broad part of the rivet is longer than the cover thickness. The plate shape of the cover permits illumination of the scale by 'exterior edge lighting, and enables the plane of the scale plate to be level with the lip of the case, thus facilitating its assembly beneath the pointer.

Title: Polymerisation of olefins
Inventor: BOHLBRO HANS
IPC: C08F10/00
Filed: 1953-03-31
Abstract: Normally gaseous olefins are polymerized in the vapour phase in the presence of a catalyst comprising a complex of a metal fluoride with boron trifluoride.  The catalyst is preferably made from an alkali metal fluoride such as calcium fluoride containing a small quantity of water, on which is adsorbed boron fluoride. Complexes derived from nickel and iron fluoride may be used but are not so effective as that from calcium fluoride.  The derivative from sodium fluoride exhibits no catalytic activity. The feed gas may be cracked refinery gases containing propylene and mixed butylenes together with some propane and butane.  In a preferred example a mixture of 19.1 per cent isobutene, 40.9 per cent n-butene and 40 per cent n-butane was passed over a catalyst made by absorbing 15.2 grams BF3 on 100 grams CaF2 containing 1.8 grams H2O.  The yield increased as the temperature was raised up to a maximum in this case of about 175 DEG  C. Temperatures of from 0 DEG  to 300 DEG  C. may be used.
