Abstract: 1338310 Supporting conveyer belts PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBERCOLOMBES and ATELIERS MECANIQUES DU DOUAISIS 19 April 1971 [16 Feb 1970] 21918/71 Heading B8A A conveyer belt 13 (Figs. 4 and 5) is supported by air pressure in a chamber 19. The air is supplied via conduits 18a, 18b and apertures 17a, 17b. An increase in load increases the area of flow between the belt and belt-support surface of the chamber 19 adjacent the apertures 17a, 17b. This results in the belt having up- and-down and lateral stability. The belt may be of hollow, tubular cross-section (Fig. 6, not shown). There may be a single longitudinally extending member 6 (Fig. 1) projecting into a chamber 5 connected by orifices 4a, 4b with pressure chambers 3a, 3b. In operation, air from chambers 3a, 3b, passes through orifices 4a, 4b into the main belt supporting chambers and then to atmosphere via apertures 8a, 8b.

Abstract: 971,348. Tufting. R. E. CONNOR. June 7, 1962, No. 22064/62. Heading D1G. A tufting tool comprises a stem having a hook at its outer end, a yarn-loop severing knife mounted on or adjacent the stem, and a resilient tuftlength gauge which lies alongside and is connected for movement with the stem, and which extends beyond the outer end of the latter. The tool shown has a stem 11 formed at its outer end with a hook 12 closable by a pivoted latch 13, and provided adjacent a handle 10 with a knife blade 20 which is protected by a guard 26. A tuft-length gauge in the form of a resilient wire 30 is adjustably secured at one end to the handle by a screw 34, and is formed at its other end with a closed loop 31, the outer limb of which carries a coloured sleeve 32. In use, one end of a length of yarn is knotted at 41, Fig. 2, to a strand 43 of an openweave base fabric, and the tool is used to draw a tuft loop 45 of yarn under strand 43 and over a loop 46 extending from knot 41, the length of tuft loop 45 being determinined by aligning sleeve 32 with strand 43. The tool is then thrust forward to sever loop 45 on blade 20. The operation is repeated at successive apertures adjoining strand 43. Fig. 5 shows a modified form of looping the yarn to the strand.

Abstract: 423,935. Binding machines. McGLASHAN, T., VILLE, A. W. DE, Spittlegate Ironworks, Grantham, Lincolnshire, and RUSTON & HORNSBY, Ltd., Sheaf Ironworks, Waterside South, Lincoln. Aug. 5, 1933, No. 22070. [Class 6 (iii)] [See also Group XXIV] In a harvesting-machine, a main slipping clutch is mounted on the power take-off shaft of the tractor and an auxiliary slipping clutch is used in conjunction with the binding and knotting mechanism, the main clutch being adjusted to slip only under a load greater than that at which the auxiliary clutch slips. The auxiliary clutch comprises a driving sprocket 7, driven from the back elevator chain, to the hub 11 of which is secured a pair of rings 13 separated by a distance piece 15 and provided with a number of wedge-shaped cam lobes 14, the inclined surfaces of which are engaged by the free ends of a pair of pawls 21 pivotally mounted on a disc 17 secured to a driven member 5, on which latter the hub 11 is journalled. The packer spindle is slidable in but rotates with the member 5. The pawls are urged inwards by springs 23 arranged around arms projecting radially from a ring 26 and passing through slots in the pawls. The longer arm 27 is received in a boss 36 on a segmental plate 32 which is secured over a cut-away part 31 of the flange 19 of the disc 17 by studs 40 passing through slots in the plate. The latter can thus be adjusted angularly on the disc 17, being held in adjusted position by interengaging teeth on the plate and flange, whereby the point of application of the springs to the pawls, and thus the load at which the clutch slips, can be varied. The shorter arm 28 is fitted at its free end with a slidable sleeve 42 having a rounded head 43 bearing on the flange 19.

Title: Process for separating plutonium by hydroxides
IPC: G21C19/46
Filed: 1945-08-28
Abstract: 859,191. Separation of plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 28, 1945 [Sept. 2, 1944], No. 22177/45. Drawings to Specification. Class 39(4). Plutonium is separated from solution by precipitating a metal hydroxide which carries down the plutonium, redissolving the precipitate, and repeating the process with another metal hydroxide. A solution of neutron-irradiated uranium is treated to remove uranium and fission products by the bismuth phosphate precipitation method as described in U.S.A. Specification 2,785,951 and the concentrated plutonium fraction in acid solution is contacted with a hydroxide of aluminium, bismuth, copper, chromium, cobalt, iron, lanthanum, nickel, or zirconium by adding a soluble salt of the metal followed by hydroxide iron, e.g. as sodium hydroxide, and stirring at 75‹C. for 1¢-2 hours. The precipitate is removed and redissolved and another carrier metal hydroxide formed in a similar manner. Before precipitating the hydroxides, sodium or potassium ferrocyanide may be added to remove iron present by precipitation ; or oxyalic or citric acid may be added to prevent precipitation of iron and bismuth hydroxides. In examples, a precipitate of aluminium hydroxide is first formed, this is dissolved in sodium hydroxide, and then a precipitate of copper hydroxide is formed which is removed and dissolved in ammonium hydroxide. Further metal hydroxide precipitations or a lanthanum fluoride precipitation may follow. Reference is made to reversing the order of the aluminium and copper hydroxide precipitations and to using hydroxides of chromium, nickel, or cobalt in place of copper hydroxide. The Specification as open to inspection under Section 91 comprises also processes, in which there is only one hydroxide precipitation ; an additional example describes the use of hydroxides of zirconium, lanthanum, aluminium and copper. This subject-matter does not appear in the Specication as accepted. Specification 853,311 also is referred to.

Title: Electroluminescent arrays laser-cooling system
IPC: H04N3/14
Filed: 1970-05-08
Abstract: 1319301 Television ENERGY CONVERSION DEVICES Inc 8 May 1970 [16 May 1969] 22368/70 Heading H4F To display a television signal on an X-Y addressable array of electroluminescent elements, row electrodes 17-21 are sequentially energized at line frequency and the video signal 31 is converted at 30 to a parallel form which is used to energize respective column electrodes 22-27 after time delays determined by the amplitude of the video signal at the corresponding points in the addressed row, so that the addressed elements are energized thereafter until the row electrode is de-energized, for periods corresponding to the desired brightness at the individual elements. As described, vertical sync pulses 29 cause the output of an oscillator 28 to be gated to rows 17-21 in turn, and horizontal sync pulses 32 actuate the converter 30, i.e. they constitute the points in time from which the delay of energization of electrodes 22-27 is measured. Each electroluminescent element 37 acts as a capacitor in a circuit 16 comprising also a resistor 35 and a threshold switching or Ovionic device 36. The device 36 is bi-directional and switches from a high to a low impedance condition when a threshold voltage in excess of a threshold value is applied, after a delay related to the magnitude of the excess voltage, Figs. 3 and 4 (not shown). When the applied voltage is switched off, the threshold turn-on voltage is lower than the original value and takes some time to return thereto, Fig. 5 (not shown). Therefore if the length and magnitude of pulses from the converter 30 is sufficient to turn the device on initially (in combination with the output of oscillator 28), the output of oscillator 28 may be sufficient and of sufficiently high frequency, Fig. 5A (not shown), to repeatedly switch the device on at its reduced threshold voltage. The delay before energization of an electroluminescent circuit may be determined by the magnitude and/or timing of pulses from converter 30. Arrays of other geometries, e.g. polar, may be used for other display purposes.
