Title: Jet propulsion system and discharge nozzles therefor
Inventor: ASHWOOD PETER FREDERICK
IPC: F02K1/30
Filed: 1954-11-25
Abstract: 788,316. Jet propulsion plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Nov. 17, 1955 [Nov. 25, 1954], No. 34254/54. Class 110 (3). In a jet propulsion system, the discharge nozzle has a retaining wall for the propulsive fluid stream including a throat portion and an outlet portion diverging downstreamwardly of the throat portion, at least one circumferentially extending fenestration in these portions at a region upstream of the nozzle outlet end for placing the fluid stream in communication with fluid outside the nozzle, means for interrupting the communication and means operable to constrict the transverse area of the fluid stream at the fenestration. The nozzle wall has a convergent entry portion 7, Fig. 2, a throat portion 8, and a divergent outlet portion 9. Four circumferentially-extending rectangular holes 10 are provided in the portion 8, and are closable by a ring 11 having four corresponding holes 13 and rotatable about the nozzle axis by means of an hydraulic jack 15. The ring 11 may instead be arranged to move axially. When the holes 10 are open, atmospheric air enters through the holes and changes the fluid flow from convergent-divergent to convergent form. A valve 21 may be opened when the holes 10 are open or closed, to admit air from the compressor of the gas turbine engine through a circumferential slit 18 in the form of a jet which impinges on the fluid stream and reduces its cross-sectional area. In an alternative construction, Fig. 5, each hole 10 has a tube 23 extending radially to an outer casing 5 and closable by a butterfly valve 25. The valves 25 are operated in unison by an hydraulic jack 15 which rotates a ring 28 connected to the valves through links 30 and cranks 27. The cross-sectional area of the fluid flow can be reduced by calipers 35, Fig. 6, pivotally mounted at 34 within a peripheral recess 32 located upstream of the holes 10. The calipers 35 are actuated by a double-ended hydraulic jack 39. A variable iris mechanism may be used instead.

Title: Shear type fluid coupling
IPC: F01P7/04
Filed: 1964-08-21
Abstract: 1,017,359. Hydraulic couplings. EATON MANUFACTURING CO. Aug. 21, 1964 [Oct. 14, 1963], No. 34346/64. Heading F2C. [Also in Division F1] To minimize decrease in torque transmission and consequent fan speed reduction at high temperatures in an engine fan-drive shear type viscous fluid coupling, viscosity decrease due to fluid decomposition is offset by venting the fluid-operating chamber 40 to atmosphere in response to temperature to effect fluid oxidisation and consequent compensating . viscosity increase. The chamber 40 includes a shear space for the fluid, such as silicone fluid, between co-operating grooves and ridges 56 of a driving member 11 fast on an input shaft 17 and a driven member 12 rotatably carried on the shaft 17 by a ball-bearing 30. The operating chamber 40 is vented through radial and axial passages 67, 61 in the input shaft, the axial passage 61 being opened in response to temperature. A plug of fusible material, preferably polyethylene, blocks the passage 61 during handling and assembly of the coupling to prevent leakage, and softens and unblocks the passage 61 at a predetermined shaft temperature corresponding to a higher fluid temperature at which the fluid decomposes. The input shaft 17 is rotatably carried by the engine block and is rotated through a belt drive and pulley 18 secured to an input shaft flange 20. Fan blades 14, 15 are secured to the driven member 12 which itself is provided with cooling fins 49. A reservoir 58 communicates with the operating chamber and means (not described) are provided to vary the fluid volume in the shear space. Axially extending openings 37 in the member 11 are provided so that during venting the oxygen in the atmosphere may contact the fluid in the operating chamber on both sides of the member 11.

Filed: 1966-08-02
Abstract: 1,157,464. Feeding webs. STANDARD TELEPHONES & CABLES Ltd. 2 Aug., 1966 No. 34578/66. Heading B8R. A tensioning roller 1 for a running web 3 is rotatably mounted on a fixed shaft 2 so as to be capable of movement under the action of a spring relatively to the shaft 2 in a direction towards and away from the web. As shown in Fig. 1, the roller 1 is mounted by means of ballbearings 4 on a core 5 slotted at 6 to slidably engage the shaft 2. A spring 7 between the core and shaft tends to move the roller 1 away from the web 1, the strength of the spring being such so that it balances the weight of the roller and core when the shaft 2 is positioned midway between the ends of the slot 6. The spring 7 may, however, be situated at the opposite side of the shaft to that shown in which case it tends to move the roller 1 towards the web 3. This arrangement may be employed if the web exerts a horizontal force on the roller 1. If however, the web force is vertical as shown in Fig. 1, an adjustable electromagnet 8, Fig. 2 (not shown) is provided acting on the roller 1 and tending to move the roller upwardly against the action of the spring. As shown in Fig. 3, wherein a web 11 is slit at 13 into strips and alternate strips pass to take-up rollers 15, 16, respectively, a separate and independently spring-biased tensioning roller as described above may be provided for each strip. These rollers may be mounted on a fixed common shaft 23 situated between two rollers 12, 14 over which all the strips pass or, alternatively, may be mounted on two fixed shafts 24, 25 so as to be situated between the take-up rollers 15, 16 and auxiliary rollers 18, 20. The rollers 18, 20 may each be a single roller engaging all the strips or may comprise a separate roller for each strip. The shafts 23 . . . 25 may be carried by means whereby they can be lowered to bring the tensioning rollers into contact with the strips. In the case of shaft 23, it is mounted in arms 26 pivoted at 27 and held rigidly or resiliently in operative position.

Title: Improvements in or relating to the purification of extraction solvents containing trialkyl phosphates
Inventor: FIELD BRIAN ORLANDO
IPC: G21C19/46
Filed: 1960-10-10
Abstract: A solvent comprising a tri-alkyl phosphate in a hydrocarbon diluent and containing degradation products produced by the combined influence of nitric acid, and heat and/or nuclear radiation is purified by contacting it with a basic liquid organic amine which is substantially insoluble in the solvent and which does not substantially extract the tri-alkyl phosphate from the solvent. The amine may be diluted with an inert liquid which is substantially immiscible with the solvent. and does not substantially extract the tri-alkyl phosphate therefrom, suitable liquids being water and liquid alkylene glycols and condensed glycols, e.g. ethylene glycol and diethylene glycol. Suitable amines are alkanolamines and alkylene diamines such as mono-, di- and tri-ethanolamine, N-hydroxymethyl diethanolamine, 3-amino-propanol, monoisopropanolamine, monoisobutanolamine, ethylene diamine and mixtures thereof. It is preferred to use monoethanolamine or mixtures thereof with di- and tri-ethanolamines. The purification process may be preceded by a preliminary washing of the solvent with an aqueous alkali and may be followed by treatment with aqueous nitric acid solution. Examples are given in which the following solvents are purified: (1) a 20% tributyl phosphate-odourless kerosene solvent containing a small amount of dibutyl phosphate to simulate degradation and which has been equilibrated with an aqueous solution of uranyl nitrate, (2) a degraded tributyl phosphate-odourless kerosene solvent with retained Hf181 equivalent to an H number of 1360, and (3) a degraded tributyl phosphate-odourless kerosene solvent with a Z number of 23000.

Filed: 1935-12-17
Abstract: 472,247. Massage and liquid treatment of the colon. DIERKER, H. E. Dec. 17, 1935, No. 34975. [Class 81 (ii)] [Also in Group XXIX] Apparatus for rehabilitating, stimulating or measuring peristalsis of the colon comprises an applicator adapted to be inserted into the rectal portion of the colon and to provide a tight seal with the rectal sphincter, a liquid inlet means connected to the applicator for supplying liquid to the colon under sufficient pressure to expand it, an outlet means connected to the applicator through which liquid may be withdrawn from the colon, an inlet valve for closing the inlet means, an outlet valve for closing the outlet means, means for indicating both positive and negative pressures always connected to the applicator so as always to permit measurement of the pressure therein and of the colon connected thereto, and means for withdrawing liquid from the colon through the outlet means under sufficient negative pressure to contract the colon. As shown in Fig. 1, the applicator 101 is attached to a flexible tube 100. Liquid under pressure is supplied from a percolator 37 through a flexible hose 36 and an inlet valve 39 controlled by means of a pedal 50. After closing the inlet valve, the liquid may be withdrawn under negative pressure through an outlet pipe 52, by opening the outlet valve 57, and also opening the valve 76 which permits water to pass through a pipe 75 and a pipe 91 to an injector 92. A valve 96 in the pipe 75 regulates the pressure of the water passing to the injector. A gauge 67 indicating both pressure and vacuum is connected to the outlet pipe 53 on the applicator side of the valve 57 A check valve is provided in a chamber 64 which permits liquid to flow only in the outward direction. As shown in Fig. 1, the outlet valve 57 and the injector operating valve 76 are both operated by means of a handle 62. With this handle in the full position the outlet valve is open, and the injector operating valve is closed. Movement in the dotted position 110 rotates a shaft 58 and causes a gate 60 to close the outlet pipe 53. Movement to the dotted position 88 causes a cam pin 86 to contact with a cam on one end of a lever 82 causing the other end of this lever to depress a rod 80 thus opening the valve 76 while the valve 57 remains open. By alternately operating valve 39 and valves 76 and 57 alternate pressure and vacuum can be applied to the colon. With all valves closed, fluctuations in pressure on the gauge 67 indicate peristalis. Flexible connections 108 and 104, Fig. 1, enable the flexible tube 100 and the applicator 101 to be removed for sterilization. The valves &c. are enclosed in a housing 30, Fig. 3. Specification 23918/02, [Class 81], is referred to.
