Filed: 1939-02-02
Abstract: 524,651. Knitted fabrics. INTERLOCK PATENTS, Ltd., REYNOLDS, W., and BONSER, F. Feb. 2, 1939, No. 3556. Drawings to Specification. [Class 74 (ii)] Patterned effects or stitch variations are incorporated in one or both of the opposed rib webs of an interlock knitted fabric in which down the wales a number of successive sinker bars of one web are interposed between successive sinker bars of the other web. The patterns &c. may be the result of yarn changes, tuck, float or miss stitches, transferred or spread loops &c. and may be so devised as to shape the fabric. The two webs may be knitted of contrasting yarns. The fabric may be made on an interlock machine with four feeders at the first two of which the even cylinder and odd dial needles knit at the last two feeders. At appropriate intervals and at the required feeders certain selected or predetermined needles may be controlled to tuck, miss &c. in any known manner to produce, e.g., the upper and lower portions of a length of fabric suitable for a vest &c. the waist portion being shaped by there being fewer or no tuck &c. stitches.

Title: Improvements in or relating to windmills
IPC: F03D9/28
Filed: 1931-02-04
Abstract: 383,264. Windmills. CUVELIER, P. A. I., Hotel de l'Univers, Chatelguyon, Puy-de-Dome, France. Feb. 4, 1931, No. 3587. Convention date, Feb. 5, 1930. Void [Published under Sect. 91 of the Acts]. [Class 110 (iii).] A windmill is fitted with a centrifugal governor which controls mechanism to operate a tail surface which in turn rotates the windmill head about a vertical axis to move the vane-wheel relative to the wind direction and thus decrease or increase the speed of the mill. Vanes 11 drive a shaft 3 and through gears 9, 10 and crank shaft 11, reciprocate a vertical rod 33 which is connected to pistons of a pump. A sleeve 21, Fig. 1, loosely mounted on the shaft 3, is connected by a sprocket wheel 14 and a chain with a wheel 15 which drives a screw spindle 16 connected by links to a spindle of the tail 32. A governor 18 is fixed to the shaft 3 and with speed variation slides a double-toothed wheel 20 towards either of the single-toothed wheels 13 or 23. The wheel 13 has peripheral teeth which engage a chain mounted on a sprocket 12 on the crank shaft 11. The gear case 2 is rotatable on rollers 6 on the pylon 7. A pawl 24, pivoted to the gear case 2, locks the wheel 20 in the disengaged position when the tail moves to a position at right-angles to the vane wheel. The pawl is actuated by a pin 25 on the screw spindle. In an alternative arrangement, Fig. 3, a sliding sleeve 50 has bevel wheels 49, 51 attached, and the whole slides on the shaft 3 through the action of the governor upon change of speed of the shaft 3. Either of the pinions 49, 51, turns a bevel wheel 54 on a screw spindle 55 to cause vertical movement of a nut 56 and thus turn a bell-crank lever 61 about a pivot 60 to rotate the tail 32. A wedge-shaped extension 59, of the fork 58, engages with the circumferential extension 52 of the pinion 51 when the tail surface is at right-angles to the vane wheel. The vane shaft 3 rotates a vertical shaft 48 through bevel gears 46, 47. In a further arrangement the sleeve 50 and attached gears 49, 51 slide on an extension of the vertical shaft 48. The link mechanism connecting the screw spindle with the tail-operating rod may be replaced by flexible cables and return springs. The Specification describes a tandem piston arrangement operated by the reciprocating rod 33, the piston being separated by a partition. The pistons are secured to the shaft by keys which are designed to facilitate dismantling the pistons and their valves. Means to secure the cylinder head in position are also described including catches or bolts held by gravity or springs, or the head may be screwed into position.

[Also in Division C6] In the fermentation of wort in a closed, fluid-tight tank under pressure (between 1.5 and 60 p.s.i.) of the carbon dioxide gas produced, the liquid mass is stirred in such a manner as to cause the liquid to follow an invariable cyclic path, the direction and speed of movement of the liquid at any point being invariable and sufficient to keep the liquid in the state of a light homogeneous fluid having a specific gravity ranging from 0.15 to 0.40. The circulation of the homogeneous fluid at rates of from 0.3 to 3 times per minute, may be produced either by a screw or propeller 3 or 9, Figs. 1 and 2, or by the reintroduction of scrubbed carbon dioxide under pressure through line 15 or 19, Figs. 3 and 4, respectively, or by both means. The cross-sectional passage area of the ascending portion of the liquid may be 0.08-0.5 that of the descending portion. As a result the speed of the upward stream e.g. 0.5 to 10 metres per second, may be substantially 2-12.5 times that of the downward stream. In continuous fermentation, the make-up of fresh wort, by volume, per minute represents not more than onehundredth of the bulk. The fermenting wort may be supplied with oxygen.

Title: Process and apparatus for producing alkali metal and/or alkaline earth metal phosphates
IPC: C01B25/39
Filed: 1964-01-31
Abstract: <PICT:1035971/C1/1> In the preparation of alkali and alkaline earth metal phosphates by introducing alkali and/or alkaline earth metal compounds into hot gases containing P2O5 obtained by the combustion of phosphorus, the graphite walls of the reaction chamber are previously impregnated with a phosphate melt, and are cooled so that the temperature of inner surfaces remains above the M.P. of the phosphates to be produced.  In the impregnating melt, the alkali metal oxide to P2O5 ratio is less than 1.3. As shown, graphite walls 2 of reaction chamber 1 have bore-holes and channels for cooling gas, e.g. air, whereby the temperature of the walls is maintained at preferably 20-50 DEG  C. above that at which the product melt begins to flow. A jacket 3 may optionally surround the walls. Liquid phosphorus is fed through conduit 5 and atomized in nozzle 4 with compressed air. Additional air or oxygen is fed through conduit 6. Steam may optionally be added with the reactants.  The metal compound, e.g. the oxide or hydroxide, carbonate, chloride or crude phosphate, suspended in carrier gas, is blown tangentially into pipe 7 surrounding nozzle 4 to impart spiralling motion.  The phosphate melt produced, maintained molten if necessary by supplementary heating, is withdrawn from the chamber via discharge 11, developed as a dam so that there remains in the chamber at least the amount of melt produced in ten minutes.  Off gas pipe 13 having baffle plates 14 is located in the vicinity of the liquid surface, preferably immediately above, and leads to scrubbing tower 16. Nozzles 15 spray scrubbing liquid into the hot off-gases containing entrained phosphate and excess P2O5, reducing their temperature from 500-900 DEG  C. to 100 DEG  C. or less. Scrubbing liquid is recycled by pump 17, concentrated phosphate is removed therefrom at 18 and fresh water added at 19.
