Title: Method for oxidizing trivalent titanium in solid titanium oxide-containing materials
IPC: C22B34/12
Filed: 1958-09-10
Abstract: An oxidic titanium-containing material comprising trivalent titanium oxide is agglomerated and then partly oxidised by means of an oxidising gas containing free oxygen in the presence of water and an electrolyte below 100 DEG C. and thereafter oxidising with a similar gas at a temperature, preferably gradually increasing, in the range 250-400 DEG C. such that autoxidation and consequent glowing is avoided.  The process is particularly applicable to titanium oxide concentrates produced by thermal reduction in a rotary furnace, which have a particle size of 1-5 microns and are pyrophoric at 150 DEG C. and above.  The agglomeration preferably consists of pelleting to a particle diameter of 3-15 mm. using, e.g. dilute sulphuric acid.  The first oxidation stage may be conducted as described and claimed in Specification 809,753, to which reference is made.  It is preferred in the second oxidation step to pass a hot gas through a layer of the material at such a velocity that the heat of reaction is substantially immediately removed, but the temperature may be controlled, e.g. in a rotary furnace, multiple-hearth furnace or tunnel kiln, by restricting the access of air.  The oxidising gas may also be passed counter-currently through a moving layer of pellets. Where air is used to cool the oxidised material, the warmed air may be used in an oil burner and/or in admixture with the oxidising gases.  In the examples, the first oxidation is performed by supporting a layer of pellets on an open wire screen and exposing to the air: in the second oxidation a stationary grate in an oil-fired chamber is employed and a preheated mixture of air and combustion gases passed therethrough.  Specifications 754,453 and 791,366 also are referred to.

Title: Method of treading untreaded cross-ply pneumatic tyres
Inventor: HAWKINSON RAYMOND P
IPC: B29D30/54
Filed: 1969-06-10
Abstract: 1,237,045. Applying treads to new and worn tyres. PAUL E. HAWKINSON CO. 10 June, 1969, No. 29276/69. Heading B7C. A method of treading an untreaded new or worn pneumatic cross-ply tyre to reduce the rolling radius and produce a tyre of lower profile, comprises the steps of axially spreading the sidewalls 3 and their respective beads 2 apart to radially contract the crown portion 4 of the tyre to substantially the desired reduced rolling radius, applying a circumferentially inextensible belt 10 over the portion 4, applying a tread strip 12 over the belt and portion 4, axially spreading the sidewalls further apart to reduce the outside radius of strip 12 enabling insertion of the tyre into an annular tread matrix mould 13, radially expanding the tyre therein by bringing the sidewalls mutually closer and by exerting radially outward pressure against the inside of the carcass, and curing the tread strip within the mould. The outer surface of the tyre is coated with adhesive, after, in the case of a worn tyre, abrading with a rotary rasp or buffing wheel. The sidewalls are moved by spreaders 7, each having bead-engaging lugs movable towards and away from each other by opposite-handed screw-threads. The belt comprises one or more layers of rubberized parallel cords, e.g. glass fibres, extending circumferen. tially or at an angle to the mid-circumferential plane not exceeding 15 degrees, the ends of the belt overlapping and the belt being of less axial width than the tread strip. After insertion of the tyre in the mould, the spreaders 7 are removed and the tyre is fitted to a rim enabling the interior of the tyre to be pressurized during curing.

Title: Improvements in or relating to electrical counting circuits

Filed: 1952-05-07
Abstract: 735,553. Electronic counting-apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 7, 1952, No. 29300/53. Divided out of and addition to 735,515. Class 106 (1). [Also in Group XL (c)] In a circuit comprising a plurality of eitherside-stable valve pairs arranged to count impulses on a binary basis, each impulse to be counted is fed to every valve pair so that change over of such a pair can only occur during the period occupied by the impulse. In one embodiment, Fig. 1, the left-hand gas-valves VI, V3 ... of the pairs V1, V2, V3, V4 ... are normally discharging so that gates G1, G2 ... are disabled. The first pulse fires V2 to extinguish V1 thereby enabling the tube G1 to fire momentarily on receipt of the second pulse which it passes both to V1, which refires, and to the valve pair V3, V4. In this pair V4 fires, gate G2 being unable to fire since its trigger is shunted by the discharging, of V3. V4 extinguishes V3. The next pulse changes over V1 and V2, G2 not firing because its trigger is shunted by V1. The next pulse, however, changes over V1, V2 and fires G1 to pass a pulse to fire V4 and also to enable G2 (which is now prepared by the non-conducting state of V3) so that G2 transmits the incoming, pulse over its anode to the next valve pair V5, V6; and so on. In a second embodiment. Fig. 2, the incoming pulses are applied to each valve of each pair via an associated gate circuit. An incoming pulse can only be effective on a valve pair, e.g. V5, V6, provided all the left-hand valves of the preceding pairs are cutoff. Otherwise some or all of the rectifiers MR22 ... MR25 are coriducting and the incoming pulse is shunted through V1 or V3 or both. Moreover a pulse can only be effective on a valve provided its mate is conducting, e.g. for a pulse to be effective on V4 that valve must at the time be non- conducting so that MR20 is forward biased. Specification 712,643 is referred to.

Classes 100(1) and 100(2) A machine for multicolour printing on continuous metal bands comprises a series of printing stations each comprising a printing roller 6, an impression roller 7 associated with each roller 6, and a pair of sprocket rollers 8, 9 one at either side of the roller 6, a perforating machine 5 in advance of the printing rollers of the machine, a plurality of guide rollers 11, 12, 13, 14, 15 so disposed that a loop of the band is formed between two of these rollers intermediate a pair of consecutive printing stations. As shown, a band 10 is drawn from a supply roll 2 and passed over a pair of feeding rollers 4 to the perforating machine 5 which forms a row of perforations along each edge of the band. The band is drawn from a loop 10 DA and around guide roller 11 by a sprocket roller 8 at printing station A. The band 10 is then printed by the rollers 6, 7 and is fed by a sprocket roller 9 to a drying drum 20 having longitudinal ribs .21 forming a space between drum and band. The band passes around guide rollers 12, 13, and 14 before forming a loop 10 AB. The loop 10 AB frees the band from stresses which may exist in the band to ensure correct feeding without lateral deviation and errors in registration. Printing stations B and C are similar to station A except that at station C the reverse side of the band is printed by passing the band through the rollers 6, 7 in a direction opposite to the progressive travel of the band. The rollers 11 an 15 at each station are carried on movable arms which cause their simultaneous movement into and out of operative position dependent upon the side of the band to be printed. If desired, the band may be cooled to a predetermined temperature, prior to further printing, by passage around the rollers 11 which in this case have a thermostatically controlled cooling liquid circulated through them. The band passes through feed rollers 4 before being rewound on a drum 3.

Abstract: 871,539. Liquid/liquid contacting. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 2, 1959 [Sept. 8, 1958], No. 29904/59. -Class 46. Fig. 5 illustrates a three series-connected column but the elements may be placed in several rows close to each other side by side and/or may be displaced with respect 'to each other in the vertical direction. During the extraction process the heavy solution which is supplied at 4 is extracted by the lighter organic solvent supplied at 5. The pulsed column, is provided with thin perforated plates 6. At every stroke of the pulsing means 7, the two phases are forced 'to and fro through the openings in the plates thus bringing about an effective extraction. 8 is an outlet pipe for the lighter liquid while the heavy solution is discharged at 9. The pulsing movement of the liquid is used for the transport of the liquid between the column elements. The pulsed volume is at least equal to the volume contained in each connection line so a liquid element in position A in Fig. 5 will be moved to position B during one pulse stroke. During the pulsation, the liquid column within the connection pipe will, therefore, oscillate to and fro between associated column elements. The difference in the densities of the two liquid phases gives rise to a certain valve action at the ends of the column elements so that a net transport of the light and the heavy phases respectively, through the connection line, is brought about The amplitude of the pulse stroke in the connection line is of course considerably greater than in the column and a separation of the two phases in the connection line usually will not take place. Since emulsification is also not desirable, shorter column elements and wider connection lines should be used. If on the other hand separation should occur in particularly wide connection lines, this can be avoided by suitable means for bringing about a turbulent flow within the connection lines. However, in very wide connection lines permanent gas cushions may be formed, and in this case the wide connection line may be replaced by a plurality of parallel smaller connection pipes. The top of each column element may also be provided with ventilation devices, by which gas may be removed continuously or intermittently, but this measure is believed to be necessary in exceptional cases only.
