Title: An improved method of and means for facilitating physical or chemical reactions in masses of loose material
IPC: B01J19/18
Filed: 1923-01-19
Abstract: 192,089. Deschamps, J. J. Jan. 21, 1922, [Convention date]. Blast, applications of.-To facilitate physical and chemical reactions in porous masses of material subjected to the action of fluids under pressure or undergoing distillation, evapcration or chemical action, variations of pressure are produced in the chamber containing the material under treatment by producing pulsations in two or more fluids supplied to the chamber, the pulsations produced in the fluids being of different amplitude or periodicity or of the same periodicity and out of phase. The invention is stated to be applicable to blast furnaces, but is shown in Fig. 1 as applied to a container in which two gases or vapours supplied through conduits A, B act upon a mass of material, and the gases resulting from the reactions escape through a conduit G controlled by a valve H. The conducts A, B are provided with valves C, D which are opened and closed at intervals to produce pulsations in the manner stated above. The container may be provided with any number of valve-controlled inlets and outlets. The gases may be supplied to the container by injectors, in which case valves which are opened and closed intermittently to produce the pulsations are provided in the pipes supplying the injecting-fluid. Fig. 2 shows a rotary disc valve J provided with apertures K of different size and adapted to open and clcse the fluid-supply conduit so as to produce variable pulsations in the container. When it is desired to produce rapid pulsations, a pivoted oscillating plate M, Fig. 4, or a piston P, Fig. 5, may be provided in a chamber communicating with the container or conduits connected thereto. The pulsations may be set up by the displacement of the fluid serving to operate a whistle, syren or the like. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in the method of and apparatus for producing pulsations wherein the supply to and exhaust from the container may be operated intermittently, or the valves in the inlet pipes may be operated simultaneously. This subject-matter does not appear in the Specification as accepted.

Patent GB-615330-A (GB)
Title: Improvements in or relating to spinnerettes
IPC: D01D5/06
Filed: 1946-01-25
Abstract: Metallic spinnerettes for the spinning of protein solutions are treated with a solution of a basic nitrogen compound insoluble in and having a repellent action on the coagulating bath, the said compound containing a long-chain alkyl radical having more than eleven carbon atoms, and then removing the solvent in order to deposit on the spinnerette a film of the said compound.  The preferred compound for use as a coating is lecithin, but other phosphatides, the sphingomyelins and cephalins may also be used. Other suitable compounds are stearamide, stearylamine, stearylguanidine, laurylamine, N,N - dimethyldodecylamine, 3-stearoxypropylamine, myristylamine, 6-octadecoxypropylamine, N,N1-distearylalanyl amide and the long chain alkyl cyanamides, dicyandiamides, melamines, guanamines, biguanides, guanylureas, in cases of which the alkyl radical has twelve or more carbon atoms.  These materials are viscous liquids, plastics or solids and they may be thinned or dissolved in such volatile solvents as benzene, gasoline, xylol, chloroform and carbontetrachloride.  The solution may contain 0.01 to 25 per cent of the compound.  The evaporation of the compound may be encouraged by heat (which should not be enough to melt the compound) and by the flow of gas such as air, carbon dioxide, nitrogen, &c. through the spinnerette to prevent clogging of the apertures.  In an example, a 5-15 per cent solution of collagen in dilute organic acid solution is satisfactorily extruded through a metal spinnerette coated with a film of lecithin deposited thereon from a chloroform solution into a spinning bath containing ammonium sulphate from 35 per cent to saturation and enough ammonia to maintain the pH at 7.8.  The Specification refers also to prior attempts to prevent protein material adhering to metallic spinnerettes by dissolving lauryl pyridinium chloride and cetyl pyridinium chloride in the spinning bath, and by using paraffin wax, mineral oil, stearic acid, palmitic acid, lauryl alcohol, stearyl glyceride and palmityl stearate.  The Specification as open to inspection under Sect. 91 refers to the application of such of these basic nitrogen compounds as are heavy liquids by smearing on to the outer surfaces of the spinnerette and into the holes thereof.  This subject-matter does not appear in the Specification as accepted.
