Patent GB-419641-A (GB)
Title: An improved process for the production of monocalcium phosphate
IPC: C05B11/08
Filed: 1934-03-08
Abstract: Monocalcium phosphate is obtained by reacting crude phosphate with sulphuric acid to obtain a solution fully saturated in the hot state with monocalcium phosphate and almost saturated with dicalcium phosphate, separating the residue and deposited calcium sulphate, and cooling to crystallize monocalcium phosphate. Liquor obtained by washing the residue, and preferably also the mother liquor from the crystallizing step after evaporation if necessary, are re-used in the process.  In the latter case the amount of sulphuric acid used is correspondingly reduced.  By so selecting the concentration of sulphuric acid that the water introduced with it in the form of washing water is removed as water of crystallization of the calcium sulphate and of the monocalcium phosphate, evaporation of the mother liquor from the crystallizing step is rendered unnecessary.  The mother liquor containing free phosphoric acid may alternatively be used for the production of dicalcium or ammonium phosphates.  Two examples are given.

Abstract: <PICT:0815029/III/1> <PICT:0815029/III/2> <PICT:0815029/III/3> A plant comprises two hermetically sealed separators, a pipe connecting an outlet of the first separator with the inlet of the second separator, a pump having a capacity greater than the discharge from the outlet arranged in the pipe, a throttling member at an outlet of the second separator, and a device for maintaining constant pressure at one part of the pipe.  Fig. 1 shows a system ensuring a constant feed to a plant (Fig. 2) for the treatment of a fatty oil.  A supply tank 1 is connected to the first separator 26 by a pipe 2 in which are disposed a heater 4, a pump 3, a valve 11 and a mixer 5.  A diaphragm-controlled valve 8 is connected to the pipe by pipes 7, 22 to give a constant pressure drop across the valve 11, and hence a constant flow of oil to the mixer which is supplied with a measured quantity of reagent.  Oil freed from gum is discharged from the separator 26 and fed to the second separator 34 by a pipe 27 in which are located a valve 28, a heater 30, a pump 31 and a mixer 32 to which a controlled flow of neutralizing agent is supplied.  A pipe 38 including a diaphragm controlled valve 43 connects the pressure side to the suction side of the pump 31 and ensures a constant pressure in the pipe 27 at the manometer 44.  Neutralized oil is discharged from the separator 34 through a pipe 35 having a valve 36.  The pipe 35 may connect the separator 34 to a further separator, or to a further series of separators, so that the oil may be further treated to obtain a refined product, all adjacent separators in the plant being connected by a piping system similar to that extending between the separators 26, 34.  In the soap-making apparatus shown in Fig. 3, soap stock is mixed with a graining electrolyte in a mixer 46 and fed to the first separator 49 by a pump.  Neat soap from the separator 49 is fed to the second separator 55 by a pipe 50 containing a valve 51 which maintains constant pressure in the outlet of the separator 49, a pump 52, and a mixer 53 to which fitting electrolyte is supplied. A valve 66 opening at a predetermined pressure drop is connected to the suction and pressure sides of the pump 52.  Fitted soap is discharged from the separator 55 by a pipe 56 having a valve 57 which maintains a constant pressure at the separator outlet. Spent lye is discharged from the separator 49 by a pipe 59 having a valve 61 maintaining constant pressure in the separator outlet, and nigre is discharged from the separator 55 by a pipe 60 having a valve 62 maintaining a constant pressure at the separator outlet.  The nigre is pumped to the mixer 46 for further treatment in the separators.

Title: Method and apparatus for treating continuously moving strands of material in long orcontinuous lengths
IPC: D06B3/16
Filed: 1962-03-01
Abstract: 956,314. Treating textiles in long lengths with gases or vapours. AMERICAN CYANAMID CO. March 1, 1962 [March 1, 1961], No. 7983/62. Heading B5B. [Also in Division D1] Continuously moving strands of filamentary textile material, particularly polyacrylonitrile filamentary material in the form of a tow or a yarn, in long or continuous lengths is treated with a hot gas or vapour comprising steam under superatmospheric pressure by a method in which a positive flow of a preheated liquid is directed over and through the strands while they are exposed to the action of the gas or vapour, whereby the transfer of heat from the gas or vapour to the strands is facilitated. The term " strands " is intended to include monofilaments and multifilaments in yarn, fabric, ribbon, rope, tow or other continuous form. The liquid may be water or other aqueous liquid preferably at the same temperature as the gas or vapour, e.g. 105 to 155 C. As shown in the drawing, the process may be carried out in an apparatus comprising a pressure vessel 10 having tow inlet-sealing means 12 and tow outlet sealing means 14. From the driven feed-in rolls 16 and 18 a tow 20 of polyacrylonitrile filaments passes into the main body portion 22 of the vessel 10. By means of suitable plaiting means (not shown) the tow is laid transversely upon the endless open mesh conveyer belt 24, which carries the tow from the tow-inlet end 26 to the tow outlet-end of the vessel 10. In this vessel the tow is treated, while it is being conveyed in a relaxed state on the belt 24 with saturated steam at about 105 to about 155 C., preferably 115 to 140 C. Saturated steam under a pressure sufficient to provide a temperature within the above ranges is introduced into the vessel 10 through a number of inlets, two of which are shown at 30. The tow is also treated on the belt 24 with preheated water 32 which is sprayed on the continuously travelling tow by means of a number of nozzles 34 attached to the header 36 to which water at a pressure of e.g. 30 to 60 p.s.i.g. is fed by the conduit 38. The force of the water sprays is insufficient to disarrange the tow and the rate of supply of water is not so great as to cover the tow on the belt 24 with a layer of water. When the tow approaches the end of the conveyer belt 24 it is removed therefrom and withdrawn from the pressure vessel 10 by means of the driven take-off rolls 40 and 42 after passing over the guide rods 44 and 46 and through the tow-outlet sealing means 14. Condensed steam and excess liquid passing through the open mesh conveyer belt 24 is drained off through the outlets 48 and 50. The strands may be of natural fibres or of man-made fibres such as regenerated cellulose, cellulose derivatives, vinyl polymers, polyesters, polyamides and polyolefines. The invention enables the treatment of the strands to be effected more rapidly and more uniformly than hitherto.

Abstract: 994,970. Clamps. E. STANIFORTH. March 6, 1962 [March 7, 1961], No. 8184/61. Heading E2B. [Also in Division A4] A clamp for the assembly of a tubular assembly structure such as platforms, storage racks or panels, comprises a main tube socket 10 and a side socket 12 with the axis of the sidesocket intersecting that of the main socket, and fixing means at each socket for securing a tube therein, the effective plane of the end of the main socket adjacent to the intersection being normal to the axis of the main socket and the intersection lying in the plane. As shown the arrangement is such that when two such clamps are arranged together with the inner ends of the main sockets in contact and with the main sockets coaxial the axes of the side sockets lie in a common plane. In the construction shown the inner ends of the clamps are planar and this permits the side sockets to have any angular relationship within a given range. In other constructions each main socket has a toothed inner end, the medial plane of the teeth being the effective plane above and the teeth can take three forms. In one form the teeth are of ratchet shape, in another form the teeth are of rectangular shape and in a third form the teeth are of V-shape. In each case the two clamps can be adjusted in steps over the given range of angular relation of the side sockets. In the main and side sockets in each form the fixing means are grub screws.
