Title: Improvements in or relating to burners for liquid fuels
IPC: F23D11/10
Filed: 1949-03-11
Abstract: 670,970. Liquid-fuel furnaces. GHELFI, S., and RUDOLPH, C. March 11, 1949, No. 6757/49. Class 51 (i). [Also in Group XI] In a liquid fuel burner, the conical tip 21 of an atomizer nozzle 13 projects through an opening in the rear of a cylindrical screen 3, coaxial with the nozzle and delimiting a pre-combustion chamber for flame formation, so that combustion air admitted through said opening and along said conical tip produces a whirling motion in said chamber near the nozzle tip, and a nozzle pin 24 of constant cross-section can be caused to project from the fuel outlet, without varying the cross-section thereof, so that atomizing air or steam discharged from said nozzle will impinge against said pin and effect an intimate admixture of air and fuel within said chamber at the mouth of the nozzle. As shown, an atomizer 13 is clamped to a bracket 10 secured to a plate 1 through which the conical nozzle head 21 projects. Cylindrical screens 3, 7 concentric with the nozzle head 21, and with each other, are adjustably bolted to the plate 1, the screen 3 having an inwardly-directed flange 6 adjacent the plate so that pre-heated primary air may be supplied therebetween transversely to the nozzle axis. The transverse primary air flow causes whirling of the atomized fuel within the precombustion chamber formed by the screens 3, 7, to produce a flame very close to the nozzle. Liquid fuel is supplied via an adjustablythrottled passage 17 in the bracket 10 to an injector tube 19 having a conical nose 20 with a conical grooved nozzle ring 22 clamped therearound by the nozzle head 21. The nozzle ring grooves, which may be axial or helical, provide for the passage of pressure air or steam to the annular discharge space bounded by the conical walls of the nozzle head, and injector tube nose, the air or steam being super-heated in coils 31 in contact with the burner flame before passing to the atomizer. The nozzle pin 24 extends through the injector tube 19 and has a screwthreaded portion 25 formed with a conical seating 26 and passing through a screw-threaded plug at the rear of the atomizer to terminate in a head 28 whereby the pin may be retracted within or projected from the mouth of the injector tube to vary the angle of discharge of the pressure air or steam and thus vary the shape of the flame. Further variation of the flame shape and length is obtained by axial adjustment of the screens 3, 7. The nozzle pin 24 may be of square section with the edges in contact with the interior of the injector tube 19 so that turning movement clears the surface of combustion residues.

Title: Improvements in the production and treatment of artificial textile materials containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1935-03-07
Abstract: Artificial filaments, yarns, and like textile materials having a basis of an organic derivative of cellulose, containing at least 40 per cent on the weight of the cellulose derivative of a plasticizer compatible therewith in high proportions, and containing substantially no volatile softening agent, are subjected to stretching at temperatures of at least 50 DEG  C.  The plasticizers used are compatible in proportions of the order of at least 50 per cent of the weight of the cellulose derivative.  The materials treated may be of cellulose acetate, formate, propionate, butyrate, nitro-acetate, or other cellulose ester, methyl, ethyl, or butyl cellulose, or other cellulose ether, ethyl cellulose acetate, oxyethyl cellulose acetate, or other cellulose ether-ester. Specified plasticizers are dibutyl, diamyl or other tartrate ester, di-methyl or ethyl phthalate, di-methyl or ethyl glycol phthalate, dibutyl glycol phthalate, triethyl citrate, cresyl glyceryl diacetate, methyl cyclohexanyl oxalate, benzyl benzoate, triacetin, triphenyl acetin, p-toluene sulphon-amide, the isomeric xylene sulphonamides, and other aromatic sulphonamides, and benzyl alcohol. The plasticizer may be incorporated in the spinning solution.  The filaments may be obtained by dry or wet spinning methods.  The proportion of plasticizer in the materials to be stretched may be 40-100 per cent or more based on the weight of cellulose derivative. The materials may be stretched in the form of hanks or other packages, or while travelling from bobbin to bobbin, or from the spinning apparatus to a winding device.  They may be stretched while arranged in parallel alignment.  Stretching may take place in one or more stages.  The materials may be passed through a vessel containing air, or other gas or vapour at raised temperature and at normal or raised pressure, or they may be passed through a hot liquid.  The plasticizer may be removed during or after the stretching operation by treatment with alcohols, benzene, toluene, carbon tetrachloride, dichlorethylene, diethyl ether, or di-isopropyl ether, or by water or aqueous solutions of alcohols after the stretching.  In an example, cellulose acetate yarns containing dibutyl tartrate in high proportion are led from bobbins through a reed and while in warp formation are stretched while passing through a vessel containing hot air.  The plasticizer is then removed by treatment with a hydrocarbon solvent.

Title: A method of treating under low pressure a proportion of a liquid circulating under high pressure in a closed cycle
IPC: F22B1/18
Filed: 1958-03-07
Abstract: 859,277. Purifying liquids. SULZER FRERES S.A. March 7, 1958 [March 15, 1957], No. 7438/58. Class 46. [Also in Group XL(a)] The purification of liquids circulating under high pressure in a closed cycle, e.g. cooling water used in atomic reactors, is facilitated by passing the liquid under high pressure through a lock chamber, closing the lock chamber pressure-tight to entrap some of the liquid, expanding the trapped liquid, treating it under low pressure in a purification plant, returning it to the lock chamber, closing the lock chamber, putting the lock chamber under high pressure again by connecting it to the closed cycle, and again passing liquid to be treated through the lock chamber. As shown, a proportion of impure water flowing under pressure along pipe 1 is tapped off at 3, loses heat in a heat exchanger 5 and, if necessary, in a cooler 6, and with valves 9, 10, 11 and 12 closed and valves 7 and 8 open flows into a lock chamber 15, displacing from this chamber into heat exchanger 5 the still cool water purified in a preceding operation. This purified water returns to the closed cycle at point 4 in pipe 1. After lock chamber 15 has been filled with impure water, valves 7 and 8 are closed and valves 11 and 12 are opened to permit expansion of the water, which is passed by means of pump 17 through a purification plant 18 under low pressure and thence to lock chamber 15 as purified water. A second lock chamber 16 may be operated alternatively with lock chamber 15 so that while one fills with impure water at high pressure the other is at low pressure and its contents are being purified in plant 18.
