Phosphoric acid and gypsum are obtained by acidulating phosphate rock with a mixture of phosphoric and sulphuric acids, to form a slurry of calcium sulphate hemihydrate crystals in a concentrated phosphoric acid solution, which latter is separated and withdrawn as product; the calcium sulphate hemihydrate crystals are washed with an aqueous liquid containing sulphuric acid with or without a minor amount of phosphoric acid, the composition and quantity of the washing liquid and the temperature being such as to prevent transformation of the hemihydrate to another crystal form and to make the liquid adhering to the washed crystals a suitable component for an aqueous recrystallization solution to which the hemihydrate is then transferred, and in which it is recrystallized to form gypsum. The recrystallisation solution, including the said component, contains 2 to 25% by weight of sulphuric acid, and less than 20% of phosphoric acid, calculated as P 2 O 5 .

Abstract: 1,270,935. Spinning yarns. T.M.M. (RESEARCH) Ltd. 1 Aug., 1969 [16 Aug., 1968], No. 39281/68. Heading DIF. Yarn is formed in a continuous process whereby a sheet or strip of film of synthetic plastics material, e.g. polypropylene, is converted to staple fibres which are spun by an open-end spinning device. As shown, film F from roll 11 is divided by roller 38 and each strip is flattened, straightened and perhaps heated by passage through rollers 12, 13, 14, 15, then advanced by rollers 16, 17, across the pins 19 of a slitting roller 18, rotating at a different peripheral speed therefrom, so that subsequent stretching between pairs of rollers  21, 22, and 23, 24, produces staple fibres which are fed by rollers 25, 26 to the feed tube 27 of a spinning device 28 which forms yarn Y. The fibres may be opened by a beater between- or following the pairs of stretching rollers and/or a beater cylinder covered with saw-tooth wire may act on fibres emerging from rollers 25, 26, Fig. 3 (not shown) and prior to delivery to tube 27.

Abstract: 1438363 High pile fabric knitting machines GLEOINT MILLS INC 21 Aug 1973 [6 Nov 1972] 39464/73 Headings D1C and D1K In sliver feeding means for a high pile fabric knitting machine, a doffer 28 and main cylinder 30 are driven from the ring gear 24 of the machine at selected constant speeds while the drive of the sliver feed rolls 40, 44 is controlled by fabric density control means including gears selectable to vary the speed of drive of these rolls. As shown, the knitting machine has eight sliver and yarn feeding knitting stations 1-8 each preceded by a pattern mechanism 11-18. Rolls 40, 44 have wire coverings 42, 46 to shred the sliver and rotate at e.g. <1>/100 speed of main cylinder 30, which also has a wire covering Gearing 24 drives, through gearing, a shaft 64 carrying a cone of gears 72 of increasing diameters and numbers of teeth. Keyed on a shaft 74 parallel to shaft 64 is a gear 84 which meshes with an idler gear 88, these gears being axially movable by a manual control to engage gear 88 with one of the gears of cone 72 to vary selectively the speed of rotation of shaft 74. A sprocket wheel 112 on shaft 74 drives a sprocket wheel 116 on the element 120 of a magnetic clutch 118 through which rolls 40, 44 are driven is rotatable on a tube 122 and includes clutch plate 124. When a second clutch element 128 is electrically energised, plate 124 is attracted to engage a plate 130 on element 128 which is then rotated. Each clutch 118 is controlled by a patterning mechanism including a needle selection pattern drum 150. By varying the speed of feed rolls 40, 44 it is possible, with the same sliver, to knit high pile fabrics of different pile density.

Abstract: 948,480. Bearings. ROLLS-ROYCE Ltd. Oct. 26, 1962 [Nov. 3, 1961], No. 39534/61. Heading F2A. In a ball or roller bearing at least one of the races is flexible and is so loaded by displaceable loading means that a non-circular track is formed for the rolling elements. In an embodiment, a flexible outer race 15 is mounted in a housing 16 which is received by a casing 17. The race 15 is displaced by three equi-spaced plungers 23, each of which is urged by a spring 22 mounted in a recess of the housing 16. Clearances, provided between the race 15 and the housing 16 and between the plungers 23 and their relative holes 24, communicate with an oil feed hole 25, Fig. 2, in the end of a wall member 12 so that damping can be effected. A hole 26, which passes through the casing 17 and into the housing 16, can receive a thermocouple. The plungers 23 could have arcuate shoes, or a single arcuate shoe common to the three plungers, fitted to their outer ends. In another embodiment, an inner race 44, Figs. 4 and 5, is flexible and is displaced by plungers 63, having arcuate shoes 65 at one end thereof and a heavy flange portion 64 at the other end. The plungers are retained in apertures 62 by a cylindrical abutment 57 and, on rotation of a shaft 53, are urged towards the flexible race 44 by centrifugal force. In a modification, springs are positioned between the abutment and the flange 64 of each plunger 63 so as to ensure a loading force is exerted even when the shaft 53 is stationary. The Specification states that the displacing of a flexible race reduces slip between the rolling elements and their races.

Abstract: 928,438. Phase-sensitive rectifiers; automatic position control. UNITED AIRCRAFT CORPORATION. Nov. 8, 1961 [Nov. 18, 1960], No. 40008/61. Class 38 (4). In a phase-sensitive rectifier an A.C. input 12 is applied in push-pull to a pair of transistors with emitters biased beyond cut-off by variable bias from a potentiometer 28-32 and a pulsed timing signal (e.g. a ¢ sec. pulse of 2 volts every 4 seconds) is applied to the bases to permit the transistors being alternately conductive only when the A.C. input signal exceeds a predetermined value. Further, gating diodes 56, 60, 76, 80 are connected between the transistor collectors and a pair of output transformers 68, 84 so that each collector output in turn is directed in the same direction through one only output transformer dependent on the phase sense of the second A.C. input 50 (of equal frequency) applied in push-pull across the two collectors (only one diode gate being conductive at any instant). The resulting rectified full wave output is then applied to switching transistor 94 or 100 to produce a D.C. output from either collector circuit 96 or 102. Transformer coupling 88 between the emitter and base of transistors 22, 24 provides, by regeneration, a rapid turn-on time. The input A.C. (e.g. of 400 c/s.) may indicate, by its voltage, deviation of an element from a controlled position. Only if this is excessive is the rectifier rendered operative to provide an additional fast re-positioning signal for the controlled element.

Title: Improvements in or relating to the hopping and heat treating of brewers' wort and apparatus therefor
Inventor: ROYSTON MICHAEL GEORGE
IPC: C12C7/20
Filed: 1960-11-30
Abstract: <PICT:0947403/C3/1> Sweet or hopped brewers' wort is heated at substantially atmospheric pressure solely by injection of steam into the body of the wort to effect both boiling of the wort and stabilization by denaturation of the protein content of the wort and precipitation of the denaturation products; it is stated that subsequent precipitation is eliminated or, at least, very considerably reduced when the wort does, as is inevitable in its processing, contact heated surfaces and especially those maintained at high temperatures. The stabilization or denaturation referred to may be carried out at a temperature to ensure sterilization; when effected on hopped wort, it covers the required hop tannin and wort protein reactions also.  The degree of vaporization produced by the steam injection should be sufficient for the removal of those malt flavour compounds, including aldehydes and esters, which might otherwise combine in later heating stages with other wort constituents and form undesirable flavour compounds.  In one embodiment, untreated wort entering through a line 1, Fig. 1, is stabilized and sterilized by treatment with steam from a vapour line 5 in the stabilizing vessel 3, at substantially atmospheric pressure, and is then passed through a heater 18 of any suitable type and a flesh chamber 19; the vapour released from the wort in the flash chamber is passed back to the steam inlet line 5. Flow of wort is regulated by valves 11 and 24 responsive to the level of wort in the stabilizing vessel and flash chamber, respectively. In the embodiment depicted in Fig. 4, provision is made for hopping in two stages and stabilizing occurs before the first hopping stage, between the two hopping stages and after the second hopping stage.
