Abstract: 1,273,008. Phosphate rock digestion; fertilizers. USS AGRI-CHEMICALS Inc. 25 June, 1969 [26 June, 1968], No. 32172/69. Heading C1A. A process for the digestion of phosphate rock includes the steps of digesting the rock in a mixture of nitric acid, potassium sulphate and ammonium sulphate to produce a filterable slurry of calcium sulphate, phosphoric acid, ammonium nitrate and potassium nitrate, filtering the slurry to separate the calcium sulphate, leaving a liquor of phosphonic acid, potassium nitrate and ammonium nitrate, which is then concentrated for the recovery of the nitrogen, potassium and phosphate values therein. In preferred embodiments (a) the separated calcium sulphate is treated with NH 3  and CO 2  and the resulting ammonium sulphate solution separated and recycled to the digestion step, and (b) the nitric acid and potassium sulphate for digestion are initially mixed, and cooled and the resulting potassium nitrate removed as a bi-product, and the ammonium sulphate is then added, and the digestion effected. The liquor separated from the digestion can be concentrated, ammoniated, granulated and dried to produce a granular fertilizer.

Title: Improvements relating to the driving gear for reciprocating piston engines particularly internal combustion engines
IPC: F02B75/22
Filed: 1932-11-15
Abstract: 400,430. Driving-gear. OUTILLAGE, R. B. V., 13, Passage des Tourelles, and KRAVITS, A., 28, Rue Le Marois, both in Paris. Nov. 15, 1932, No. 32321. Convention date, Nov. 16, 1931. [Class 7 (ii).] In a multi-cylinder engine each piston acts by means of two connecting-rods on oppositely rotating shafts, and each element, comprising a cylinder, piston, two connecting-rods and two shafts, corresponds to another element symmetrically placed with regard to the centre of the engine, the pairs of cylinders being coaxial. Where the cylinders are radially arranged, each crank pin may be connected to two connecting- rods, one from each of the adjoining cylinders. Connecting links, longitudinally or transversely arranged, may be interposed between the twin connecting-rods and their driving piston. The coaxial cylinders may be merged into a single cylinder containing oppositely moving pistons, the drive being transmitted through helicoidal gearing to a shaft parallel to the cylinder axis. Auxiliary cylinders connected by single rods to the shaft and which may be used as compressors may be placed in the angles between the main cylinders. Cylinders of more than one diameter may be used. The drive from the shafts e<1>, e<2> may be transmitted to a propeller through an encircling internally toothed crown wheel and that from the oppositely moving shafts f<1> , f<2> to a pinion h<3> on the propeller shaft. Alternatively, two internallytoothed crown wheels attached to oppositely moving propellers may be used.

Title: Improvements in or relating to timing apparatus applicable for use with glass feeding devices and for other purposes
IPC: C03B3/00
Filed: 1923-12-28
Abstract: 229,804. Wood, J. T. Dec. 28, 1923. Charging.-Relates to a timing device, partioularly intended for use with a glass - feeding device but applicable also for other purposes, such as the automatic working of a furnace - charging machine, for adjusting the various operations of such machine relatively to one another while the machine is in motion. The device comprises a number of shafts parallel with one another and having one or more cams mounted thereon, cylindrical castings adjustably mounted in the framework of the machine and carrying air valves or electrical contact makers, the castings and their valves being separately movable for retarding or advancing the operations of the machine. In the construction shown, two parallel shafts 5, 6 are journaled in bearings in uprights 2, 2<x> and long conical pulleys 7, 8 are mounted in the shafts, the inclination of the cones being in opposite directions. A sprocket wheel 10, secured to one end of the shaft 6, is connected by an endless chain to a suitable source of power for driving the device, and a belt 17 drives the pulley 7 from the pulley 8. The upright 2 is formed with circular apertures, coaxial with the shafts 5, 6, in which cylindrical castings 29, 31 fit. The fastenings are secured in place by nuts 34, 35 respectively, and by slackening these nuts the castings may be turned about their axes. Thus valves or contact makers carried by the castings can be adjusted in relation to cams which are housed within the castings and are fixed on the ends of the shafts 5, 6. The casting 29 carries an electrical contact-maker 108 operated by a plunger 120, and also a cam 105 which is formed on a sleeve 12 looselv mounted on the end of the shaft 6. The sleeve is driven from the shaft 5 through sprocket wheels 11, 14 and a chain 16. Thus by turning the casting about its axis, the timing of the operation controlled by the cam, e.g. the operation of the shears of a glass feeder, can be adjusted. Similarly, the casting 31 carries a valve 53 which controls a supply of compressed air and is operated by a cam 48. This cam, which is of variable contour, is keyed on the shaft 5 and may be moved laterally by a handwheel 44 projecting from the end of the casting. The wheel 44 enables the cam to be shafted in order to bring any desired portion of its contour in line with the operating piston 58 of the valve. The speed of the cam as a whole is varied by moving the belt 17 along the pulleys 7, 8.

Title: Method and apparatus for raising the nap of a fabric
IPC: D06C11/00
Filed: 1954-11-20
Abstract: 760,894. Napping fabrics. AA BE WOLLENSTOFFENEN WOLLENDEKENFABRIEKEN N.V. Nov. 10, 1954 [Nov. 12, 1953], No. 32531/54. Class 42 (1). The roughened nap 2 of a pile fabric 1, Fig. 1, is raised normal to the plane of the fabric by means of a driven card-clothed cylinder 4, the wire tips of which extend forwards in the direction of rotation and exert a pull on fabric 1 in opposition to a tension A; the speed of the card clothing is substantially equal to that of the fabric and the fabric leaves the card clothing under a much lower tension B when the tips of the wires are substantially normal to the raised nap and parallel to the plane of the fabric. The intensity of the treatment is controlled by adjusting the distance of the axis of cylinder 4 from the fabric. In a further arrangement, Fig. 2, for treating both faces of a fabric, the fabric 12 passes in succession over a tensioning device 14, driven napping rollers 16, 21 and a delivery roller 25 having long radial wires. A braked roller 22 tensions the fabric passing to roller 21 and restricts the tension of the fabric leaving roller 16, thus controlling the point 20 at which the fabric leaves roller 16. The speed of the card clothing on rollers 16 and 21 is substantially equal to that of the fabric, and the inclination of the wire tips is as in the Fig. 1 arrangement.

Title: Improvements relating to the manufacture of cathode ray tubes
Inventor: BAYFORD LESLIE JOHN CHARLES
IPC: H01J29/28
Filed: 1948-12-16
Abstract: 694,232. Luminescent screens for cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 16, 1949 [Dec. 16, 1948], No. 32538/48. Class 39(i) In the manufacture of cathode-ray tubes wherein a liquid film-forming substance is applied to a liquid-covered fluorescent screen of the tube, the film-forming liquid is applied from a dispenser which is supported by a carriage mounted for vertical movement in a guide, the carriage being lowered until the end of the dispenser is in proximity to the liquid-covered screen, whereupon the film-forming liquid is released and the carriage raised until the dispenser is out of the tube, the carriage and guide being so constructed that no vibration occurs to impair the formation of the film during the lowering and raising movement. As shown, the cathode-ray tube envelopes 9, Fig. 1, are held to trolleys 7 by inflatable holders 8, which may be of the type described in Specification 694,233, the trolleys being coupled to an endless belt 6. Along the upper run of the belt the envelopes are charged with phosphor suspension from device 10 and subsequently, the phosphor particles having settled on the base of the envelope, a solution of a film-forming substance is applied from a dispenser mounted on a carrier 11. As each trolley reaches a predetermined position along the upper run of the belt a lever 45, Fig. 3, on the carrier is manually depressed to cause a roller 43 to engage a recess in the trolley and thus couple the trolley to the carrier which is mounted on rails for movement therewith. During movement of the carrier 11, the carriage 23 is automatically lowered whereby dispenser tube 35 is introduced into the envelope. The lower end of tube 35 is provided with a wire 40 (as described in Specification 675,853) which serves to prevent ripples as the solution is delivered on to the liquid surface on the end of the screen, contact of the wire with the liquid automatically actuating a valve (not shown) whereby solution is delivered from reservoir 36 down tube 35. After a predetermined time, the valve is automatically closed, the carriage is raised and the carrier is disengaged from the trolley and moved backwards for coupling to the next trolley in the series. The operations are electrically controlled. During further travel of the envelope the solvent evaporates to leave a film of the organic substance, the liquid beneath the film being discharged down a shoot 55 as the belt passes over pulley 1. In their inverted position along the lower rim of the belt, the envelopes are dried by hot air, the holders 8 being finally deflated and the envelopes removed. Specification 694,286 also is referred to.
