Title: Means for abating the noise made by combustion engines
IPC: F02K1/82
Filed: 1961-03-27
Abstract: 985,561. Jet propulsion nozzles. R. W. RUMBLE. March 27, 1961 [March 25, 1960; June 17, 1960; Oct. 31, 1960], No. 11164/61. Heading F1J. A combustion engine comprises a conduit for the flow of exhaust gases in the form of a jet stream and comprises an outlet nozzle, a casing disposed around the nozzle and having a portion extending downstream of the nozzle, this portion having an inwardly-directed flange having an aperture of the same diameter as the nozzle, means being provided to reduce the pressure in the space formed between the jet stream and the casing so as to reduce the noise level. The invention is described with reference to gas turbine jet engines, the propulsion nozzle 10 of such an engine being shown in Fig. 1 and the jet stream at 12. Disposed around the jet stream 12 is a casing 18 which defines with the jet stream an annular space 20 which is connected to a source of low pressure by ducts 24. A wall 22 is disposed at the outlet end of the casing 18 extending to the outer periphery of the jet stream. The source of low pressure applied to the space 10 may be produced by means of fan blades 30 mounted at the tips of the turbine rotor blades 26 as indicated in Fig. 4, the fan discharging into an annualar duct 32 which extends along the entire length of the engine, the fan discharge passing into the intake of the main engine compressor 36. A further series of fan blades 40 may be disposed within the space 32, the blades being mounted at the tips of a row of compressor blades. In Fig. 5 centrifugal type fan blades 80 are mounted at the tips of the turbine blades 26, the fan blades being enclosed between covers 81, 82 and taking their suction from the annular spaces 20 and 32. In the embodiments described the jet stream may be divided into a number of paths by suitable vanes, the spaces downstream of the vanes being regions of reduced pressure. In Figs. 6 and 7 a series of hollow pyramid-shaped baffles 52 is disposed entirely around the periphery of the nozzle and also within the path of the jet stream, the open ends 54 of the pyramids facing downstream so that the flow of gases tends to create regions of low pressure within the pyramids thereby acting to attenuate the noise produced by the jet stream. The nozzle 50 and diffuser tube 60 are disposed within a casing structure 18, 22 as previously described. In Fig. 8, the jet nozzle comprises a convergent portion 65 and a divergent portion 66, there being an open gap between the two portions, also an outer casing 64 therearound. The flow of gases through the convergent-divergent nozzle causes a suction effect at the throat which produces a region of low pressure within the surrounding jacket space. A series of open pyramid-shaped baffles 72 and aerofoil section vanes 70 are disposed at the throat of the nozzle, the flow of gases creating regions of low pressure within the baffles.

Title: Improved process and apparatus for working and shaping dough
IPC: A21C5/08
Filed: 1927-04-27
Abstract: 270,304. Kremmling, O. April 28, 1926. [Convention date]. Dough - working machines; rolling- machines. - Elongated dough shapes are produced by subjecting pieces of dough within cells to a circular or oval movement followed by substantially rectilinear movements. The cells are of elongated hexagonal shape. Fig. 1 shows a machine in which a dividing and working head 24 is suspended from a ring 15 secured by bolts 16 to the flange 14 of a member 13 to which an elliptic movement is imparted by double crank pins 4, 6. The bolts 16 pass through segmental slots in the flange 14, permitting the head 24 to be turned so that the cells lie in the direction of the elliptic movement whereby circular shapes are produced, as shown in Fig. 14, or transversely thereto for the production of elongated shapes as shown in Fig. 10. Fig. 15. shows a modified machine in which the head 56 is driven from a crank pin 37 through a slotted member 41 embracing a fixed pin 42 and furnished with a pin 45 engaging a transverse slot in a member 46 carrying the head; a pin 48 engaging a slot 47 in the member 41 is carried by a block 49 adjustable within a slot 50 by a bell-crank lever 52 operable by a rod 55. By moving the pin 48 from alignment with the pin 37 into alignment with the pin 42, the cell movement is changed from circular to rectilinear. In a modification the circular movement is imparted to the head and the reciprocating movement through the table, the head and table being operable alternatively through a double clutch. Fig. 18 shows a modification in which the head 56 is suspended from a member 80 connected by a pin 81 to a member 77 actuated by an eccentric sleeve 74, the movement being changed from circular to rectilinear by depression of a key 83 adapted to engage a notched lug 79. Fig. 20 shows a further modification in which a head 56 having a circular movement cooperates with a table 100 reciprocable on a support 94 against the action of springs 99. A pin 102 engaging a recess 101 holds the table during the circular movement and is adapted to be depressed to permit of reciprocation of the table by the head to impart the rectilinear movement. To ensure centering of the working head in relation to the machine, when stationary, it is driven through an eccentric sleeve adapted to be turned to centralize the head by the interengagement of lugs thereon and on a flywheel; alternatively the drive is through an eccentric pin movable radially by levers operated by centrifugal force and constrained by a spring. The cells may co-operate with recesses 132, Fig. 28, in the table 34, provided with ridges 133. Specification 255,107 is referred to.

Title: Process for the production of sodium tripolyphosphate
IPC: C01G23/053
Filed: 1975-03-18
Abstract: 1473404 Sodium tripolyphosphate SOC ITALIANA RESINE SIR SpA 18 March 1975 [25 March 1974] 11314/75 Heading C1A The sulphuric acid solution resulting from the sulphate process for the production of TiO 2  from ilmenite or Ti-bearing slags is concentrated to >40% by weight and contacted in stoichiometric excess with phosphate ores at elevated temperature to liberate phosphoric acid; F and SiO 2  are removed from the solution, the solution is purified from sulphate ions, free sulphuric acid, arsenic and organic substances, sodium hydroxide is added in an amount sufficient to precipitate V, Cr and Fe and also to cause salification of the acid and the sodium phosphates are converted to sodium tripolyphosphate. In the preferred procedure, titaniferous material is dried and ground and leached with H 2 SO 4  in amounts of 1À4-2 : 1 relative to the TiO 2  content, the porous solid obtained is dissolved in water or dilute acid and the Fe<SP>3+</SP> is reduced to Fe<SP>2+</SP>, e.g. by the addition of metallic ion at a temperature of 50-80 C. The solution is clarified and then cooled to a temperature of 10-20 C. to precipitate FeSO 4 .7H 2 O, which is then separated. The residual solution is subjected to hydrolysis to precipitate Ti(OH) 2  which is separated and subjected to treatment to transform it to TiO 2  in rutile or anatase form. Both forms may be subjected to post-treatments, e.g. coating with Al 2 O 3  or SiO 2 . The solution remaining is concentrated to between 40-70% by weight H 2 SO 4  and contacted in stoichiometric excess with finely ground phosphatic minerals typically at 70-90 C. for 4-10 hours. The solution is filtered and F and SiO 2  are eliminated from the filtrate, e.g. as sodium fluorosilicate. The filtrate thus obtained is concentrated to a phosphoric acid solution with a P 2 O 5  strength of 45-55% by weight and organic substances are eliminated e.g. by adding active carbon and heating the suspension at 60-70 C. for 0À5 to one hour. B, Cr and Fe are eliminated by addition to the solution of NaOH. This is preferably done in a first step to adjust pH to 4 followed by a second step to adjust the pH to between 6À7 and 6À8. The mass is heated, e.g. at 85-95 C. and a precipitate formed is separated. The phosphate solution is preferably further purified by removal of any organic impurities and then dried by evaporation. The residue is suitably calcined at 540-560 C. for 0À5-2 hours to form a sodium tripolyphosphate. The tripolyphosphate has a greatly reduced V and Fe content and thus has improved whiteness.
