Title: Improvements in or relating to the manufacture of phosphor suspensions
Inventor: BLACKBURN ALAN PERCIVAL
IPC: C09K11/00
Filed: 1960-04-29
Abstract: Apparatus for forming a suspension of powdered crystalline inorganic phosphor in a liquid carrier medium comprises hoppers 1 and 3 for feeding controlled quantities of phosphor particles (of sizes mainly between 25 and 60 microns) and liquid carrier medium (water) into a mixing reservoir 2, a porcelain milling vessel 6 containing a multiplicity of generally cylindrical and independently movable hard ceramic milling elements 7 disposed with their axes substantially parallel, means for vibrating the vessel 6 horizontally and vertically and a pipe 8 for feeding the suspension in the reservoir 2 at a substantially constant rate upwards through the milling vessel 6.  The suspension leaves the vessel 6 through the pipe 9 and adjustable valve 10 to a mixing vat 17 where water is added to reduce the concentration of the suspension to 1.25% by weight, the suspension being then fed by a pump 19 to the first of three hydrocyclones 11, 12, 63, described in Specification 927,351, for separating the particles of sizes between 5 and 25 microns, mainly between 5 and 10 microns, which are fed under gravity to a coating suspension mixing vat 20 where controlled quantities of water and a water-soluble binder, such as ammonium polymethacrylate (Trade Name "Vulcastab"), are added.  The suspension is then fed to turret-machine apparatus, as described in Specification 917,832, for coating glass tubes 22 forming the envelopes of low pressure mercury vapour fluorescent discharge lamps. Control of the level of the suspension in the mixing vat 20 is automatically regulated by a control device 64 which shuts off the pump 19 when the suspension reaches a predetermined height, and supplies of binder and water are fed to the mixing vat 20 through electrically controlled on-off valves 38, 39, the operation of which is automatically controlled by a viscosimeter 40 and densitometer 41, as described in Specification 918,953, located within the coating through 50 or the vat 20. <PICT:0966385/C4-C5/1> <PICT:0966385/C4-C5/2>

Abstract: 694,789. Preparation of fibres for spinning. BRITISH RAYON RESEARCH ASSOCIATION. Aug. 2, 1951 [June 17, 1950], No. 15211/50. Classes 120(i), 120(ii) and 120 (iii) Prior to stapling, a tow of filaments is spread into a :sheet by feeding the filaments, while under tension, between rollers which rotate at an angle oblique to the direction of travel of the filaments and are thereto subjected to frictional forces having a lateral component arranged to increase progressively with the amplitude of lateral displacement. In the apparatus shown, tow a is fed through feed rollers, comprising a fluted roller b and a leather apron c, to a pair of conical friction rollers d and e having axes inclined relative to the axes of the feed rollers, the respective nips being parallel. Rollers d, e are driven by articulated shafts d', e<SP>1</SP> and the upper roller may be mounted in vertically floating bearings with adjustable springs (not shown) at each end to provide means for varying the nip pressure. The sheet a<SP>1</SP> passes to delivery rolls, comprising a fluted roller f and an apron g, the nip of which is inclined at at an angle not exceeding 40 degrees to that of the feed rollers. An alternative angular position of the feed roller is illustrated in dotted lines in Fig 2. Specification 693,362 is referred to.

Abstract: 723,319. Rotor driving arrangements. AKT.- GES FUR BERGBAUUND HUTTENBEDARF. June 27, 1951 [July 7, 1950], No. 15229/51. Class 35. A motor has both members A, B rotating in opposite directions and interconnected by a sun-wheel in such a way that the primary member B acts as a fly-wheel so as to provide the acceleration energy for the driven load. A brake disc 5 is mounted on the shaft of the member B. When the latter attains synchronous speed, a shoe 6 brakes the disc 5 so as to reduce the speed of B to that corresponding to the gear ratio and the kinetic energy of B is transmitted to A and the driven load. When the brakes are released the driven load immediately stops. Such an arrangement as this can be usefully adapted for intermittent loads and where the acceleration energy is relatively large. The sum of the speeds of A and B is always equal to the synchronous speed corresponding to the supply frequency.

Abstract: 437,827. Net-making machines. ROMANOV, M. R., 34, Kankrin Street, Rostov-on-the- Don, U.S.S.R. May 28, 1934, No. 15810. [Class 74 (i)] A net-making machine employing " sewing needle " type needles 33 permitting of moving the needle carrier across the shuttles, has, for handling the threads from the shuttle spools, a row of rods 20 formed at their ends with mutually perpendicular grooves, and adapted to rotate, and move periodically over the slots of the shuttle races. Each rod is advanced axially by a cam 26 to take the thread in the shallower of the two grooves, and is then rotated axially through 270‹ to form an overturned loop. The needle carrying the upper thread then passes through the deeper groove and the rod returns to its initial position, throwing off the knot formed which is finally tightened by a bar 49. The rod is rotated by a sine-shaped cam slot in a cam 29 (not shown), through a lever, and rack-and-pinion 21. During each revolution of the machine a cross-bar 32 carrying the needles is reciprocated vertically by a cam 34, and is displaced axially of the shuttles a distance equal to the shuttle pitch. The shuttle 2 is seated in a two-part receptacle 3 in which it is reciprocated by a rocker 4 actuated by the shaft 10 through a slide 9 and toothed segment 7. After unscrewing the screw 15 the receptacle 3 may be opened, and the shuttle removed. The upper thread is fed by three iron rolls 38 provided with triangular grooves, and a wooden roll 39, around which it makes a complete turn. A pressing piece 41 having a soft rubber lining 42, is actuated by cams on shaft 44, to check the thread when necessary. A thread guide 40 is depressed by cams 43 on shaft 44 when the upper thread is to be withdrawn. The net is advanced by rollers 47, 48 having needles at their ends to guide the edges of the net and three rollers 50, 51, 52, coupled by gearwheels. A brace piece 54 is reciprocated by a cam 63, through a bar 56, and a bell-crank lever 58 carrying a sleeve 57, adjustable along it. The brace piece drives the rollers through ratchets 55 and ratchet wheel 53.

Class 98(2) [Also in Group XIII] Apparatus for processing photographic film comprises a support 4 having an insert 9 of resilient material such as rubber forming a trough 11, in which developing liquid is circulated; the sides of the trough extend upwards as walls 12, 13, the film 15 moving transversely across said walls and being urged into firm contact with them, so that the walls act as squeegees to remove residual liquid from the film. The film is held down in contact with the trough and the liquid therein by a spring- loaded pressure pad 17..Below the trough is a cavity 23 through which liquid is circulated to maintain the trough and support at a constant temperature. The liquid circulating through the cavity may be the developer liquid itself, deriving from a common source of supply in a tank 25, kept at constant temperature by a thermostat 30. A pipe 28 supplies liquid to the developing trough 11, returning through conduits 34, 33, 31. Conduits 34, 33 are so shaped as to have an aspirating effect. Pipe 28 has a valve 36 which can be opened (37) to cut off the liquid flow to the trough, admitting air instead. Thus the trough can be opened and cleaned while the circulation of liquid through cavity 23 is maintained. The cavity is supplied with liquid through a feed pipe 27, returning through a pipe 31, 29, circulation being maintained by a pump 32. Specification 867,288 is referred to.
