Title: Improvements relating to yarn winding, doubling and like machines
IPC: B65H63/036
Filed: 1932-07-19
Abstract: 404,669. Guide bowls for yarn-winding machines. HIGGINSON, J., and ARUNDEL, COULTHARD, & CO., Ltd., Sovereign Works, Stockport. July 19, 1932, No. 20389. [Class 120 (ii).] In yarn winding, doubling, and like machines having a bowl or bowls 4, 5, 6, Fig. 1, around which the yarn passes on its way to the cheese b, the bowl-brakes are actuated through a frictional gripper upon or around a spindle 28 connected to the knock-off mechanism, the spindle 28 continuing to move both after it has fully applied or fully released the brake so that effective operation is ensured without the necessity for exact setting. The machine shown embodies the stop mechanism described in Specification 400,945. The brake 25, 26, Fig. 5, is mounted on a spring clip 27 embracing and gripping the spindle 28, the movement of the brake away from its bowl being limited by a stop 33, Fig. 4. The spindle 28 is operated through a crank-arm 29, a spring 31 being interposed between the arm 29 and a collar 32 on the rod 30, while the rod 30 may be connected to the stop lever d by a pin and slot connection 34 so that momentary application of the brake will be followed by automatic release. If desired the brake may be fitted to the back bowl 4 only. The brake 36, Fig. 7, for the lower bowl 5 is carried in a holder 37 on a plate 38 pivoted at 39 and having a weight 41 connected thereto by a spring 42. When knock-off occurs the bowl 5 is thrown upwards and the weight 41 first falls relatively thereto owing to its inertia, the spring 42 then acting to apply the brake to the bowl 5, which after a number of applications is brought to rest. The Provisional Specification describes the provision of pneumatic means for applying the brakes and having leak-off arrangements thereafter to reduce the braking action, and also an arrangement wherein the lift of the bowl 5 is increased for cheeses of larger diameter.

Title: Process for the industrial preparation of diammonium phosphate, concentrated calcium phosphates, mixed ammonium and calcium phosphates and alkaline phosphates
Inventor: MANCINELLI ALVARO
IPC: C05B11/08
Filed: 1950-08-28
Abstract: <PICT:0689751/III/1> The muds resulting from the lixiviation of sulphuric acid treated phosphate, with an aqueous solution of monocalcium phosphate, are suspended in water or a dilute solution of monocalcium phosphate and are again attacked with sulphuric acid to yield further quantities of monocalcium phosphate solution which, separated from the insoluble residue, mainly gypsum, is recycled to the lixiviation step.  The monocalcium phosphate solution resulting from the lixiviation may be treated with ammonia or alkali metal salts.  In the Figure, superphosphate resulting from sulphuric acid attack on bones or phosphorite passes from hopper 1 to a vessel 2 where it is treated with monocalcium phosphate solution from tank 17 and passed to separator 3.  The solid is treated in vessel 4 with sulphuric acid in the presence of dilute monocalcium phosphate solution from tank 17, and the contents of vessel 4 passed to separator 5 from which, after washing, the solid gypsum is separated at 6 whilst the aqueous solution is recycled to tank 17.  The rich monocalcium phosphate solution from separator 3 is passed to a saturator 7 where by means of ammonia, the calcium content is precipitated as dicalcium phosphate and separated at 15 by separator 8.  It may be further treated with sulphuric acid in vessel 16 to yield monocalcium phosphate.  The mother liquor containing mono and diammonium phosphate passes from separator 8 to a tank 9 to which sulphuric acid may be added if it is desired to diminish the diammonium phosphate content, and thence to a steam-heated concentrator 10, saturator 11, crystallizer 12 and separator 13.  The solid diammonium phosphate at 14 may be granulated and the mother liquor recycled from separator 8 to tank 9.  Alternatively, the solution coming from the separator 3 may be treated with sodium or potassium salts to yield the corresponding phosphates.

Title: Process for the dehydrogenation of hydrocarbons
IPC: C07C5/32
Filed: 1947-08-06
Abstract: Hydrocarbons having 6-12 carbon atoms in a straight chain are dehydrogenated by contacting the vapour mixed with hydrogen with a dehydrogenating metal oxide at a mass velocity of at least 5 mg. of hydrocarbon per sq. cm. of cross-sectional area per second. Benzene, toluene, and xylenes may be obtained from n-hexane, heptane, and octane respectively, the corresponding mono- or di-olefins may similarly be cyclized, and naphthenes such as cyclohexane and methyl cyclohexane dehydrogenated.  Gasoline fractions may be reformed. Simple dehydrogenation without cyclization may be effected using less severe conditions.  Liquid space velocities are generally 0.1-20 vols. per hour per vol. of catalyst, temperatures 450-650 DEG  C., pressures from 1-70 atmos., and ratios of hydrogen to hydrocarbon vapour of 0.5-40 by volume. Oxides of the elements in the left-hand columns of Groups 4, 5 and 6, preferably on supports such as oxides of aluminium, magnesia or silicon, firebrick, fuller's earth, clays, montmorillonite, bentonite, or the like, are suitable catalysts, particularly oxides of Cr, V, Mo or Ce on alumina.  Products may be separated and unconverted reactants recycled.  Temperatures, space velocities and other conditions may be varied along the line of flow. Examples illustrate the effect of varying the mass velocity from below 5 up to 22 mg. per sq. cm. per sec, in aromatizing a naphtha at 550 DEG  C., 3.5 atmos., and 0.5 liquid space velocity, using chromia-alumina and 4 or 8 molar proportions of added hydrogen, carbon formation decreasing and ratio of aromatics to carbon increasing.
