Patent GB-787590-A (GB)
Title: Fertilizer material
Inventor: BROWN GEOFFREY GEORGE
IPC: C01B17/04
Filed: 1955-01-28
Abstract: A fertilizer containing tri-calcium phosphate is made by heating an alumino-phosphate rock with calcium sulphate and carbonaceous material (coal, coke or anthracite) at a temperature of about 1100 DEG  C. or higher.  The reaction mixture contains 2 to 7 mols.  CaO per mol. of P2O5.  The aluminium phosphate is converted to calcium phosphate, and the aluminium sulphate formed is reduced to give sulphur and/or sulphur dioxide.  The sulphur released may be recovered in elemental form by admitting an inert gas, e.g. nitrogen, or as sulphur dioxide by blowing in air or oxygen.  In examples, alumino-phosphate rock (e.g. wavellite from Senegal), coal and calcium sulphate (preferably hemi hydrate) are mixed in proportions of 3.3 mols.  CaO and 3 mols. coal per mol. of P2O5, and the mixture ground to 85 mesh.  The mixture is then granulated with steam and dried at 60 DEG  to 80 DEG  C.  The granulated product, of about 6 mesh, is then heated in a muffle furnace or rotating kiln to 1050 DEG to 1150 DEG  C. in an atmosphere of nitrogen for 1 hour.  The sulphur and gases are collected, and the product treated with steam at 1200 DEG  to 1400 DEG  C. to remove fluorine.  The calcium sulphate used may consist of waste gypsum obtained in the processing of other phosphate rock as a filter cake which is dried at 125 DEG  C. and ground.

Title: Improvements in or relating to method and apparatus for transferring carbonated liquid from storage tanks to filling machines
Inventor: MEYER GEORGE LEO NICHOLAS
IPC: B67C3/02
Filed: 1953-01-29
Abstract: 733,819. Bottling. MEYER MANUFACTURING CO., G. J. Jan. 29, 1953, No. 2629/53. Class 125 (2). [Also in Group VI] In transferring a carbonated liquid, e.g. beer, from a storage tank 12, Fig. 1, to the filler bowl 10 of a filling machine, a valveless positive displacement rotar e pump 25, e.g. a gear pump, having a pulsation-free characteristic is interposed in the pipe to regulate the pressure and velocity of the liquid in the pipe without subjecting it to substantial fluctuations in either pressure or velocity. The pump has a high mechanical inertia whereby fluctuations in pressure or velocity due to stopping or starting of the pump will be gradual so as to retain gas in solution in the liquid. The liquid is supplied through a pipe 13 via the pump 25 and through a plurality of supply lines 40 to the bowl 10. Counter-pressure air or other gas is supplied to the bowl 10 through a pipe 50, air column 54 and pipes 60, 63. A pipe 70 receives air from the pipe 63 to a valve housing 72 which contains a nipple 73, Fig. 4, with a vertical bore 74 terminating in a valve seat 74<SP>1</SP> for a ball valve 75 which, when seated, shuts off the flow of air from pipe 70 to a valve chamber 77. When the valve 75 is unseated air flows from pipe 70 into a pipe 80 and through a pipe 81 to actuate a pressure switch 82 arranged to close and supply current to an automatic starter 86 for the pump 25. The valve housing 72 also has a bore 106 with a valve seat 107 at its upper end and containing a valve stem 105 which is in contact with a lever 100 actuated by a float member 91, 92 in the bowl 10. Under the action of the lever 100, the upward movement of the stem 105 moves the valve off its seat 107 permitting air in the valve chamber 77 and the pipe 80 to vent through the bore 106 and at the same time moves the valve 75 on to its upper valve seat 74<SP>1</SP> thus closing off the air from the pipe. 70 and opening the switch 82 to stop the pump 25. Thus when the liquid in the filler bowl 10 reaches the desired level, the pump ceases to operate and when the level drops during filling, the lever 100 is moved downwardly permitting the stem 105 and valve 75 to drop to close the bore 106 and open the bore 74 to the pipe 80 and causing the pump to start operating. The bowl 10 is provided with a relief valve 110 of the spring-pressed diaphragm type.

Abstract: 512,058. Winding coils. BOMBACK, C. H., and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd. Jan. 28, 1938, No. 2734. [Class 120 (ii)] In a coil-winding machine in which the travel of the traversing wire guide is reversed at the end of the winding of each layer by the contact of a member on the carriage with a preset stop, the member is made expansible and is expanded during the winding so that layers of decreasing length are wound; the member may be arranged so that a number of layers of the same length are wound before the member is expanded to cause the winding of layers of decreasing length. As shown the member engaging the adjustably fixed stops 34, 35 comprises a pair of arms 41 pivoted on a plate 40 extending from the traversing carriage and drawn together by a spring so that rollers 43 at the ends of the arms engage cams 42 fixed on a shaft 46 rotatable in the plate 40. The cams are similar in form and are set at an angle of 180 degrees to one another and a ratchet fixed on the shaft 46 behind the cams is engaged by a pawl 48 pivoted on an arm 49 carried by a pivot in the plate 40, the arm 49 having a projection 52 which is engaged by an adjustable projection 53 on a fixed rod 54 so that as the traversing carriage moves to and fro between the stops 34, the projection 52 rides under the projection 53 and causes the pawl 48 to be rocked against the action of a spring 51 and advance the ratchet wheel, and also the cams, a step forward. The cams shown each have a portion concentric with the shaft 46 and a snail portion so that until the concentric portions move off the rollers 43, layers of constant length are wound and, thereafter, layers of decreasing length as the increasing distance between the rollers 43 causes the reversal of the traversing carriage to take place earlier. A single cam with two cam paths may be employed and by substituting cams of different forms, coils having different lengths of layers may be wound.
