Title: Improvements in or relating to the preparation of titanium dioxide
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/07
Filed: 1953-08-06
Abstract: Titanium dioxide is produced by feeding titanium tetrachloride with an oxygen-containing gas to a fluidized bed of inert material having a particle size of 40 to 1000m  and having a nature such that on fluidizing with air at 1000 DEG C. for 100 hours at five times the minimum fluidizing velocity, the entrained fines constitute less than 5 per cent of the material originally present.  Suitable materials are silica, alumina, zircon and rutile, which may have been previously chlorinated to remove impurities.  The tetrachloride may be fed admixed with the oxygen-containing gas or as a jet of gas or liquid to the perforated plate on which the bed rests or to a point in the fluidized bed.  If desired fuel gases such as carbon monoxide may be mixed with the reactants or separately fed to the bed to supply heat, or heat may be supplied from an external source.  The temperature of the bed may be from 700-1200 DEG C., preferably 800-950 DEG C. for anastase production and 800-1100 DEG C. for rutile production.  The tetrachloride/oxygen ratio may be from 1 : 0.2 to 1 : 5.  Specification 724,193 is referred to.

Title: Improvements in continuously variable friction gearing
IPC: F16H15/22
Filed: 1928-07-27
Abstract: 314,700. Robertson, J. H. July 27, 1928. Variable-speed friction gearing of the kind in which a driven friction wheel c is mounted on a radius arm e so as to be moved eccentrically with respect to a driving-disc b to vary speed comprises supplementary gearing combined with the arm e and arranged between the driven shaft d of the variable pair and a fixed driven shaft j. The supplementary gearing shown is a toothed reducing train g, h, i, but it might be a chain pair, or a change-speed gear. The reaction of the torque of the shaft j might be arranged to move the arm e and disc c to the eccentric lowspeed position, as described in Specification 306,752, and this action might be rendered automatic in the manner described in Specification 313,303. In the arrangement shown, there is a loose wheel c' concentric with wheel c, as described in Specification 306,753, and the axial pressure required to maintain frictional engagement is transmitted through the arm e. The axial pressure may be produced by other means.

Title: A machine for turning, grinding and polishing faces on articles
IPC: B24B1/00
Filed: 1920-07-22
Abstract: 149,350. Stender, F. July 22, 1919, [Convention date]. Lathes.-A lathe has means for turning, grinding, or polishing a. number of symmetrically-disposed faces on a work-piece and is further adapted to the production of broaching-cutters by which work-pieces may be axially broached to fit a shaft produced by the machine. The holhow work spindle 1 carries a loose coupling-pinion 2, which may be driven at two speeds by engaging it alternatively with a pinion 3 fixed to the spindle or a pinion fixed to the cone pulleys. The pinion 2 engages a pinion 4 on a shaft which carries a pinion 5 driving through spur gearing a shaft 7, and a pinion 6 driving through change-wheels the lead screw 20. The shaft 7 drives through suitable bevel and spur gearing a prism 10<1> on the tool-holder 10, to which is fixed a two-part casing 11 carrying in bushes the spindles of turning, grinding, or polishing tools o. The speed of the shaft 10 and the number of tools carried are determined by the number of faces to be cut on the work-piece x. The shaft 10 carries a ball-bearing shell 13 indepenently driven from a pulley 13<a> and having a toothed pinion engaging pinions 15 which receive the coned portions 16 of the tool spindles. The tools are thus rotated round the axis 10 and have in addition an independent rotation round their own axes. A saddle Z supports longitudinal and transverse slides and a bearing block 18 on the upper slide caries the whole tool holder mechanism. To form a broaching-cutter with stepped threads, the tools are offset laterally from each other bv a distance corresponding to the steps of the threads.

Title: Device for the transmission of synchronous pulse signals
IPC: H04L27/00
Filed: 1968-05-10
Abstract: 1,210,445. Digital transmission systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 May, 1968 [13 May, 1967], No. 22281/68. Heading H4P. A digital data transmitter includes a switching modulator and a digital filter comprising a shift register. The data digit frequency, the register shift frequency and the modulator switching frequency are all derived from the same generator. In one embodiment, Fig. 1, data (e.g. Fig. 3, d) from source 1 is passed at digit frequency fb to a modulator or AND gate 3 fed by switching carrier frequency f c . The modulator output, Fig. 5a, passes to digital filter 5 consisting of shift register 7, attenuators 15-21, and summing unit 22. The register is controlled by a shift frequency f d , and f b : f c :f d  = 1: m: mn. By appropriate choice of the transfer coefficients of the attenuators a double sideband A.M. signal centred on f c . Fig. 5b, or a vestigial sideband signal, Fig. 5c, or a single sideband signal, Fig. 5d, is obtained. Of the numerous repeated pass-bands generated the lowest is selected by filter 23 for transmission. The modulator 3 may be replaced by a plurality of modulators, one at each output of the register 7. If the AND gate 3 is replaced by a modulo-2 adder a phase-shift signal is developed. To obtain a frequency shift signal, gate 3 is replaced by two AND gates in parallel, Fig. 7 (not shown), respectively fed by the data source direct and via an inverter and by clock pulses of different frequencies derived from, and integral multiples of, f b . The gates' outputs are summed and fed to the digital filter. The attenuators may be adjusted to compensate for phase error in transmission, and each stage of the register may feed one or other or both attenuators of a respective pair of attenuators, whereby lower vestigial or upper vestigial or double side-band signals are generated. The receiver, Fig. 2, is common to all of the various forms of ttansmitter. A clock signal frequency f b  is extracted from the received signal by unit 32 which controls pulse generator 26 which feeds sampling pulses, Fig. 5e, to sampling units 27, 28. If, when a sample pulse occurs, the received signal exceeds threshold levels set at 29, 30, the corresponding sampling unit generates a pulse which triggers a bi-stable circuit 33 whose output, Fig, 5i, corresponds to the original data, Fig. 3, d. The positive- and negative-going pulses in Fig. 5, f-h, correspond to the outputs of sampling units 27, 28 when receiving signals as in Fig. 5, b-d. The threshold levels are adjusted in accordance with the type of signal to be received.

Title: Improvements in overload clutches
IPC: F16D43/206
Filed: 1936-08-14
Abstract: 462,587. Overload - release clutches. HERRMANN, R. Aug. 14, 1936, No. 22391. [Class 80 (ii)] [Also in Group XXII] In a yielding-drive attachment, particularly for drilling, tapping, &c., a spindle 2 for mounting in a machine spindle carries a flange 3 provided with recesses 35, Fig. 5, adapted to receive rollers 34 rotatably mounted on radial pins 32 projecting from a ring 5 loosely supported on the spindle 2. A spring 15 acting between the ring 5 and an adjustable cap 12 screwing in an outer sleeve 11 presses the rollers into contact with the recesses. Ball bearings 19, 20 form abutments of the spindle 2 and the sleeve 11 on the driven tool-holder F. Rollers 31 also mounted on the pins 32 transmit the drive from the ring 5 to a clutch sleeve 21 by means of recesses 38 therein, and the sleeve 21 is normally pressed downwards by a spring 26 to cause teeth 24 thereon to engage recesses 25 in a flange 18 on the tool-holder F. On encountering excessive resistance to rotation, the rollers 34 ride out of the recesses 35 into shallow recesses 37, Fig. 5, in the flange 3, thereby allowing relative rotation between the flange and the clutch sleeve 21 and causing pins 28 on the flange to engage inclined surfaces 30 in recesses 29 of the sleeve, thus raising the sleeve and positively disengaging the clutch teeth 24 from the recesses 25. The forward edges of the teeth 24 are bevelled at 40 so that the teeth may pass freely over the flange 18 in the raised position, without transmitting drive to the toolholder. On reverse rotation of the spindle 2, the square rear edges of the teeth 24 engage the edges of the recesses 25, thereby rotating the tool in the reverse direction and causing the rollers 31 to return to the recesses 35. The pins 28 thus return to the positions shown in Fig. 5, in the recesses 29, and the clutch teeth 24 are fully engaged again.
