Abstract: 753,633. Turbines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 29, 1954, No. 18970/54. Class 110(3) In a turbine having an annular array of circumferentially spaced stationary nozzle vanes for directing motive gases to a bladed rotor, cooling liquid supply means are mounted adjacent the nozzle vanes for introducing liquid spray into the stream of motive gases, with a number of discharge openings directed downstream and uniformly spaced adjacent selected nozzle vanes between groups of the other nozzle vanes of the annular array. In the gas turbine shown in Figs. 1 and 2, water or other liquid coolant is supplied through a pipe 26 to a longitudinally extending passage 25 within a guide vane 20a, and thence through a number of nozzles 28 at the downstream end of the vane 20a, to impinge on rotor blading 15 and cool the latter. There are a number of the guide vanes 20a, spaced equally among normal guides vanes 20. In the embodiment shown in Fig. 3, each guide blade 35 is notched at 36 to receive a radiation shield 37 and a tube 38 bent into an almost complete circle with one end (not shown) closed and adjacent to the other end 40 which is bent inwardly as shown. The cooling liquid enters through the end 40 and is discharged through a number of spaced openings 41. Fig. 5 shows an embodiment in which a tube 45 extends along the trailing edge of each guide vane 43a. The latter are spaced equally between groups of the more numerous normal guide vanes (not shown). Each tube 45 is closed at its radially inner end 45a and is welded at 50 to the corresponding vane 43a. The cooling liquid is supplied through the outer end of each tube 45 and discharged through an opening 46. To allow for expansion, a sliding fit is provided between each tube 45 and an apertured sealing member 47 which is secured to the turbine casing 30.

Filed: 1921-07-16
Abstract: 185,908. Old, R. G., and Hill, F. W. July 16, 1921. Tyre and like inflating and deflating valves.-- A tyre valve is provided with an inner tubular stem fitted with a valve head and carrying a non- return valve, so that a positive closure of the air passage may be obtained by screwing down the sleeve after inflation. The outer tube a, Fig. 1, is provided with a screwed sleeve b having a collar c by which an airtight joint is obtained against a washer d. A tubular stem e is adapted to slide within the sleeve b, rotation being prevented by a stud h engaging in a groove i. The stem is operated by a nut f which is prevented from moving axially by a collar g rotatably mounted in a recess in the sleeve c. The inner end of the stem e is recessed to receive a non- return rubber valve k, and carries a plug o having a valve disc to close the air passage p. When the tyre is to be inflated, the stem e is raised until the collar l forms an airtight joint with the washer m, and the air passage p is opened. After inflation, the stem e is forced downwards to close the air passage p. In a modification, the valve o may be a conical rubber plug and the valve k of metal. In another modification, Fig. 4, the stem e is rotatable and is operated by a member f, while the valve o is rotatable relatively to the sleeve.

Patent GB-381602-A (GB)
Title: Substituted naphthalene derivatives
Filed: 1931-07-10
Abstract: Naphthalene derivatives are manufactured by the action of a cyanide on a nitroso-naphthol or an azo compound derived from a naphthol. The products are probably cyanoaminonaphthols, together with which are obtained other products the constitution of which is unknown. The process is preferably performed in aqueous or alcoholic suspension with the aid of heat.  In examples: (1) crude a -nitroso-b -naphthol is treated in aqueous suspension with potassium cyanide solution; (2) 1-benzeneazo-2-naphthol is treated in alcoholic suspension with potassium cyanide solution (aqueous), yielding a product which is probably 1 - amino - 2 - hydroxy - 4 - cyano - naphthalene, together with a second product; the starting material may be replaced by 1-p-sulphobenzeneazo - 2 - naphthol sodium salt; (3) 4-benzeneazo-1-naphthol is treated with potassium cyanide in aqueous alcoholic suspension, yielding a product which is apparently 4 - amino - 1 - hydroxy - 2 (or 3) - cyano - naphthalene; the starting material may be replaced by 4-p-sulphobenzeneazo-1-naphthol sodium salt.  Other starting materials specified are the sodium salts of 1-benzeneazo-2-naphthol-6 : 8-disulphonic acid, 1-benzeneazo-2-naphthol-3-carboxylic acid and 1-p-sulphobenzeneazo-2-naphthol-3-carboxylic anilide, which yield products believed to be substituted 1-amino-2-hydroxy-4-cyanonaphthalenes.

Title: Improvements in apparatus for separating a fluid mixture into at least two products streams
IPC: B01D3/42
Filed: 1955-07-12
Abstract: <PICT:0787763/III/1> In a fractionation column supplying fluids at different levels, the concentrations of the supplies at two levels are automatically maintained within limits by common means controlling the column in response to analysis of the fluid in two different regions of the column.  In Fig. 1 a feed stream containing butadiene, butene-2 and acetylenes is supplied to a fractional distillation column 10 through a conduit 11 in which rate of flow is maintained constant by automatic control of a valve 13.  The level of liquid in the column is maintained constant by automatic control of a valve 21 in a conduit supplying steam to a heater 19. A liquid kettle product containing a major portion of butene-2 is withdrawn through a conduit 15 in which rate of flow is maintained constant by automatic control of a valve 54 through a pneumatic controller 51.  An overhead gaseous stream containing a major portion of butadiene, withdrawn through a conduit 16 is maintained at constant pressure by automatic control of a valve 42 through which the stream passes on its way to a condenser 26.  The condensate is collected iu an accumulator 29 the level of liquid in which is maintained constant by automatic control of a valve 35 in an output conduit 34.  Pressure in the accumulator is maintained constant by automatic control of a valve 45 in a conduit bypassing a condenser 26.  Rate of flow from accumulator 29 through a conduit 31 to column 10 for reflux purposes is maintained constant by automatic control of a valve 33.  A sample of the liquid at a predetermined level in column 10 is passed through a conduit 56 and a signal dependent on the concentration of butadiene and acetylene in the sample, as derived by an ultra-violet photo-electric detector 57, controls valve 54 through pneumatic controllers 60 and 51 to maintain the concentration of butadiene within predetermined limits.  A sample of the liquid at a higher predetermined level in the column is passed through a conduit 64 and a signal dependent on the concentration of acetylenes in this sample, as derived by an infra-red photo-electric detector 65 also controls valve 54 through pneumatic controllers 67, 60 and 51 to maintain the concentration of acetylene below a predetermined value.  In a modification pneumatic controller 60 directly controls valve 54, the automatic control system responsive to rate of flow in conduit 15 being dispensed with. In another modification the acetylene concentration is measured at a higher level and when it is below a predetermined value control of pneumatic controller 60 is automatically transferred from controller 67 to a further pneumatic controller responsive to variations in the butene content in conduit 31 as detected by another infra-red photo-electric detector.
