Title: Improvements in converting salt mixtures containing ammonium chloride into a granular form
IPC: C05C3/00
Filed: 1932-09-29
Abstract: 403,781. Fertilizers. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.-(I. G. Farbenindustrie Akt.-Ges.; Frankfort-on-Main, Germany.) Sept. 29, 1932, No. 27051. [Class 111.] A granular fertilizer containing ammonium chloride is obtained by bringing a moist mixture containing ammonium chloride and a carbonate of an alkaline earth metal, e.g. calcium or magnesium, in a comminuted state into a granular form by agitation and drying, The granulation may be assisted by the addition of suitable substances favouring cementation, for example, clay, loess, marl, loam and bauxite or soluble substances such as lime and water soluble salts, for example the sulphates, nitrates or chlorides of alkali metals, ammonium, calcium, magnesium, aluminium or iron, or mixtures thereof. These additional substances may be added dry or as an aqueous solution or suspension and the necessary water content may be thus supplied. The water may also be supplied by spraying, by the addition of steam, as an aqueous solution of the ammonium chloride or as a moist pulp containing the alkaline earth or magnesium carbonate. The agitation may take place in a rotating tube or on a shaking sheet followed by drying, or the drying and agitation may take place together in a rotary oven provided with hot gases in co- or countercurrent. Examples are given.

Title: Improvements in braking control systems for winders and the like
IPC: F16D65/28
Filed: 1950-11-06
Abstract: 691,982. Hydraulic brakes for hoist gear. BRITISH THOMSON-HOUSTON CO., Ltd., WILD & CO., Ltd., M. B., BATTY, A. W. H., LIDDIARD, A. H. C., and McVEIGH, E. M. C., [Representatives of LIDDIARD, H. W. C.]. Sept. 27, 1951 [Nov. 6, 1950], No. 27061/50. Class 103 (i). A fluid-pressure control system for winding drum brakes of the type normally applied by a weight 2 or a spring, comprises a pressure release system for the brake applying cylinder 3 which operates in such a way as to provide a rapid take-up of slack in the brake rigging and thereafter gives a degree of braking when the winding machine is raising loads which is more sensitive than that provided for lowering loads. Fluid pressure, preferably oil pressure, is supplied to the cylinder 3 by way of inlet 5 and the operator's control valve 4, which are of known type. On release of the brakes, the fluid exhausts into a chamber 6 closed by a throttle valve 7 which may be adjusted by a piston in a cylinder 14 to such a volume that it permits any slack in the brake rigging to be rapidly taken up, further release of the brakes being controlled by the valve 7. The valve 7 is controlled by a pressure-operated device 8 supplied by a displacement pump 9 from a storage reservoir 13, the pump being driven by the winder so as to give full operating pressure at a fraction of full speed when raising loads, excess pressure being by-passed by a relief valve 12. A non-return valve 15 is arranged to pass oil when the winder is lowering loads so that the pump and pipework are kept full of oil for both directions of rotation. Member 11 is a second adjustable by-pass which allows pressure in cylinder 8 to fall when the winder is stationary. Member 10 is a further throttle valve dependent on the position in the wind and does not form part of the invention.

A rotatable member of a watch movement train, comprising a shaft 4 which carries two active elements such as a toothed wheel 2 and a pinion 3 for co-operation with adjacent members in the train, is mounted at least at one of its ends on a fixed stem 11 which protrudes from a frame element 5 of the movement. A bore which houses the stem 11 is enlarged at 12 and surrounded thereat by a narrow annular plane face 15 abutting a step 7. Excessive rocking under shock is prevented in that the other end of the shaft will engage the side of a depression 17 in a top frame plate 19. In a modification, Fig. 3 (not shown) a flat surface of the shaft end engages the plate to prevent rocking. In another embodiment, Fig. 2 (not shown) a balance staff which carries, as active elements, a balance and a table roller, rotates on thin stems (28, 30) at each end.

Filed: 1973-06-09
Abstract: 1426290 Rolling mills DAVY-LOEWY Ltd 18 July 1974 [9 June 1973] 27556/73 Heading B3M [Also in Divisions G1 and G3] In a rolling mill a measuring device 6 produces a signal representing the combination of shape and camber of the rolled material and means are provided for measuring the camber alone, the signal from this being subtracted at 14 from that from 6 to produce a measurement of shape alone. "Shape" refers to the flatness of the strip while "camber" relates to thickness variations across its width. The device 6 comproses a plurality of feeders across the width and is as described in Specification 1,160,112. As shown the camber signal is derived at 13 from a device 8 which measures thickness variations across the width and thickness measurers 9, 10 which together derive the reduction that occurs in the rolls. This latter may alternatively be derived from respective speed measurements. The signal form 13 is delayed by the transit time of material from 8 to 6. In Fig. 2 (not shown) a single device such as 8 is arranged on the downstream side of the rolls and Fig. 3 (not shown) illustrates this applied to a reversing mill, in which the devices 6 and 8 are duplicated, one set on each side, with appropriate switching. Alternatively, the camber may be determined by the device described in Specification 1,360,608, in which the rotation of a plurality of wheels across the width is detected magnetically. The shape measurement from 14 may be displayed and/or used to control the shape by selective roll bending or cooling.

Secured to the frame tray 94 is a stub axle 96 on which the wheel 91 and a pawl and ratchet mechanism 97 are mounted. A flint guide channel 98 is secured to the underside of the frame lid 95, and has an aperture 99 for the spring end 100 which engages in a flint pusher 101. The cover 105 may be rotated on a mounting screw 104 to permit the replacement of the flint, a projection 106 on the cover engaging the spring end 100 during rotation to move it away from the flint. A new flint is inserted through an aperture 107 in the lid 95. Movement of the spring end 100 is halted when the flint 92 is almost worn away. An operating lever 110 is pivotally mounted to the casing at its lower end and is spring-urged to project through a slot in the casing.

Vegetable preparations.-A nutritive extract is obtained from vegetables by combined treatment with a solution of alkali phosphates. and ultraviolet rays in substantial absence of free oxygen. Albumen-containing leguminous materials, such as pease meal, which are rich in mineral salts may be treated with normal sodium or potassium phosphate, while with leaf vegetables and roots, such as cabbage and carrots, which are rich in vitamines, di-sodium and di-potassium hydrogen phosphates may be employed. The digestion may be assisted by constant agitation and by the use of reduced pressure or vacuum, and may be carried out in an atmosphere of nitrogen, hydrogen, carbon dioxide or other gas without free oxygen. A moderate temperature, e.g. not above 60‹ C., is employed. The extracts obtained may be concentrated or desiccated under reduced pressure or vacuum or by atomization, or by a combination of these processes, and may be mixed. In an example, pease meal, soaked with a dilute solution containing potassium phosphate and sodium chloride, is agitated and iradiated at a moderate heat in a vacuum digester. The air is replaced by nitrogen or hydrogen and an aqueous paste containing calcium, magnesium. and ferric hydrates is gradually added, and the digestion continued for 1-1¢ hours, a milky extract being obtained. A second extract is derived from the treatment of a mixture of vitamin-rich vegetables, e.g. cabbage, spinach, green kale. lettuce, carrots &c. with a. dilute aqueous solution containing disodium and dipotassium hydrogen phosphates and sodium chloride, the air being replaced by carbon dioxide.
