Title: Process for the production of high-value titanium dioxide pigments
IPC: C01G23/053
Filed: 1947-12-31
Abstract: In the production of titanium dioxide pigments by hydrolysis of solutions of titanium salts, there are employed inoculatory titanium dioxide-containing substances produced from alkali metal (including ammonium) titanium halides.  Thus, ammonium chloride may be added to titanium sulphate solution, and hydrogen chloride introduced at about 2 DEG  C. to precipitate ammonium titanium chloride, which is then dissolved in water to yield a concentration of 50 g/l. TiO2 per litre, neutralized with alkali hydroxide, and heated at 80 DEG  C. for half an hour.  This inoculatory solution is added to titanium sulphate solution containing 100-200 gl. TiO2 per litre, and heated for 1-2 hours at 80 DEG  C. to precipitate hydrated titanium dioxide, which readily forms rutile at temperatures below 900 DEG  C.

Title: Improvements in and relating to Pneumatic Tyres
IPC: B60C9/17
Filed: 1967-08-01
Abstract: 1,160,831. Pneumatic tyre. MICHELIN & CIE (Compagnie Generale des Etabs. Michelin). 1 Aug., 1967 [1 Aug., 1966], No. 35372/67. Heading B7C. A pneumatic tyre has a crossed cord reinforcement beneath the tread and in a part of each sidewall extending from a bead to substantially the mid-height of the tyre and a radial cord reinforcement in the other parts of the sidewalls, the radial cords being integral with oblique cords forming part of the crossed cord reinforcement of at least one of the sidewalls. A typical tyre of the above construction is shown in Fig. 1 wherein broken lines represent oblique cords and full lines radial cords. As shown, the reinforcement comprises two plies 2, 2<SP>1</SP> each extending from about the mid-height of the tyre around a bead wire 8, 8<SP>1</SP> to a point 4, 4<SP>1</SP> in the region of the edge of the tread. Cords in overlapping sections of the plies in the regions 2A, 2<SP>1</SP>A, and beneath the tread 3 have opposite obliquities. In modifications, the reinforcement may comprise (a) a single carcass ply extending from about the mid-height of the tyre in one sidewall around the bead wires to the same position in the other sidewall and a crown reinforcing ply extending over the width of the tread located above the carcass ply, see Figs. 4-6 (not shown); (b) two superimposed carcass plies extending from beadwire to beadwire, a crown reinforcing ply located between the two carcass plies, and plies located between the two carcass plies in the region of the beadwires, see Figs. 7-9 (not shown); or (c) a single carcass ply extending from beadwire to beadwire, a crown reinforcing ply located above the carcass ply, and two plies located in the sidewalls and extending from a beadwire to about the midheight of the tyre, see Figs. 10-12 (not shown). Tyres of the above construction may be made by laying a ply of oblique carcass cords on a tyre building drum, laying plies of cords of obliquities differing from that of the carcass cords in the region of the crown and of each bead, and bringing the cylindrical structure to tyre shape, the obliquities being chosen so that the expansion resulting from shaping leads to the reinforcement arrangements indicated above. One or more of the plies laid on the carcass ply may be integral parts of the carcass ply.

Title: Improvements in or relating to hydraulic drives for automobile vehicles
IPC: B60K17/10
Filed: 1935-12-21
Abstract: 472,619. Controlling and driving motor vehicles. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M., [Firm of]). Dec. 21, 1935, No. 35444. Void. Convention date, Dec. 24, 1934. [Classes 79 (ii) and 79 (v)] [Also in Group XXIX] In an hydraulic drive for motor vehicles comprising two speeds, at least one of which is through a torque converter, and the change from one speed to another is made automatically in accordance with the speed or torque, the critical speed or torque at which the automatic gear change takes place can be varied or preselected by the driver at will. The second speed may be through another torque converter, and hydraulic clutch, or an hydraulic controlled mechanical clutch. In the construction shown, the engine 1 drives the vehicle through hydraulic gear 4 comprising an hydraulic clutch and a torqueconverter. The gear 4 is controlled by a lever 5 operated by solenoids 15, 16 energized by a battery 9 through contact strips 14, 13 on a speedometer 7 driven from the vehicle axle 3. The contact strips are carried by a ring 19 rotatable on the speedometer by means of a handle 20. When the speedometer pointer 12 is on the strip 13, the solenoid 16 is energized, if a switch 11 is closed and the gear lever 5 is moved to the left to bring the torque converter into operation ; when the pointer 12 is on the strip 14 the solenoid 15 is energized, if a switch 10 is closed, and the gear lever 5 is moved to the right to cut out the torque converter and bring the hydraulic clutch into operation. As shown, the change-over occurs at a speed of 70, but by rotating the handle 20 the critical speed can be changed as desired. The switches 10, 11 are closed only when the accelerator pedal 6 is depressed so that no gear-change takes place, even if the speed has risen above or fallen below the critical speed, unless the pedal 6 is depressed and the throttle is therefore open. The gear-lever may be actuated by the speedometer by hydraulic, pneumatic, or mechanical means instead of electrical. If the gear-change is controlled by the torque, a dynamometer is used instead of the speedometer.

Title: Fluid-controlling valves
IPC: F16K41/10
Filed: 1935-12-23
Abstract: 463,340. Valves. SAUNDERS, P. K. Dec. 23, 1935, No. 35555. [Class 135] [Also in Group XXVI] Relates to fluid-control valves of the kind having an axially-movable valve member connected with the body or casing by a metal bellows which renders a stuffing-box unnecessary and protects the actuating spindle from the fluid. Fluid enters at 11, passes through an opening in a partition 13 and leaves at 12. A tubular member 15 is screwed into the body at 14, is provided with radial apertures 18, and its lower end is jointed at 17 to the partition 13 and is formed as a seating 16 for the valve member which is built up of a main ring 19, a sleeve 20, a flexible ring 21 and a sealing ring 22, these parts being held together by a screw 23. The collapsable device, in the form of a metal bellows 24, has, at its lower end, an axially extending flange 25 adapted to be clamped between the rings 19, 21 by a wedgelike engagement of sleeve 20 with ring 21. The bellows, therefore, is attached to a non-operative face of the valve member and is supported internally by the sleeve 20. The upper end is clamped between metal ring 27 and flexible ring 28, the latter, and ring 21 being, e.g. of fibre. The valve is actuated by a hand wheel 30 attached to a screwed spindle 31 with reduced end 33 having a part - spherical surface 34 adapted to engage either a block 35, or the upper inturned end of the sleeve 20. The tubular member 15 screens the bellows from the direct flow of fluid. During closing, the main flow is cut off by the ring portion 19 of the valve covering ports 18. Dismantling is effected by unscrewing a nut 37 on member 15 which, upon abutting a cap 32, causes member 15 to be unscrewed. In a modification, Fig. 2, the outer convolutions of the bellows are supported by rings 38, e.g. of white metal, formed by mounting the bellows on a mandrel and pouring the metal down the interior and through the openings. In a further modification, Fig. 3, the upper end of the bellows is out-turned and is clamped between rings 39, 40 to which pressure is applied by the cap 32. The upper ring 40 is formed with a key 41 engaging a slot 42 in the sleeve 20 to hold the latter against rotation.
