Title: Tertiary phosphine oxides and methods of preparing same
IPC: C22B60/02
Filed: 1962-11-20
Abstract: The invention comprises tertiary phosphine oxides of formula <FORM:0973925/C1/1> wherein R is phenyl, p-chlorophenyl, 2-hydroxyethyl or R111OOC CH2CH2- where R111 is hydrogen or C1-6 alkyl; R1 is hydrogen, C1-8 alkyl or phenyl; R11 is C1-8 alkyl, phenyl, p-substituted phenyl (e.g. by chlorine, bromine, hydroxy or C1- 6 alkoxy, or naphthyl; or R1 and R11 taken together may complete a cyclopentyl, cyclohexyl or 1-indanyl group.  Compounds other than those in which R111 is hydrogen are prepared by reacting, in the presence of a concentrated mineral acid, a secondary phosphine R2PH which has a pKa  less than 2 with a carbonyl compound of formula <FORM:0973925/C1/2> The compounds in which R111 is hydrogen are prepared by similarly reacting such a carbonyl compound with bis (2-cyanoethyl) phosphine. The products may be used in extracting heavy metal values, e.g. uranyl. Reference has been directed by the Comptroller to Specification 923,532.

A nozzle 25 for discharging aerosol material in a fan shaped spray of generally elliptical cross-section from an aerosol can 11 having a discharge valve 16 and an actuator 17 consisting of actuating flap 18 and pin 19 engaging valve plug 20, comprises a bore 33 having an open inner end adapted to receive material from the aerosol can, the outer end of the bore terminating in an end wall 35, and a circular cylindrical discharge orifice 37 extending through the end wall 35 to the outer surface of the nozzle, which surface is V shaped adjacent the orifice, the V shaped surface being formed by sloping side walls 40 preferably disposed mutually at right angles, thereby giving the outer edge of the orifice 41 the general shape of two semi-ellipses. The end wall is formed by two oppositely sloping plane surfaces 34 lying on opposite sides of a plane containing the bore axis and the apex of the V-shaped protruberance, and being disposed such that they cut at right angles a further plane lying at right angles to the firstmentioned plane and containing the bore axis. Surfaces 34 intersect a further plane surface 35 disposed at right angles to the bore axis, the lines .of intersection being parallel. Each wall 41 and each surface 34 is preferably disposed at substantially 45‹ to the bore axis. The nozzle may be provided with a stem 26 which fits adjustably within passageway 27 in the actuator. The nozzle may be formed with a rectangular flange 31 constructed such that its long axis coincides with the long axis of the spray pattern. The V-shaped protruberance 40 then lies on the exterior of flange 31. Aerosol spray cans utilising this nozzle are suitable for spraying paints, lacquers, enamels, cosmetics, insecticides, lubricants, rust-proofing compounds and medicaments.

Title: Aircraft propulsion system
Inventor: SUTTON JAMES FRANKLIN
IPC: B64C29/00
Filed: 1962-11-26
Abstract: 973,464. V.T.O.L. aircraft. LOCKHEED AIRCRAFT CORPORATION. Nov. 26, 1962, No. 44570/62. Headings B7G, B7K and B7W. [Also in Division F1] An aircraft comprises two passages through the fuselage, the axis of each passage extending downwardly and rearwardly, a plurality of injector nozzles located at the upper part of each passage, and gas producing means which is connectable either to the injector nozzles or to a horizontal propulsion nozzle. Fig. 2 is a plan view, and Fig. 4 a vertical lateral section of an aircraft having a fuselage 1, wings 2, and fairings 4 above the wings, each enclosing a gas turbine engine 7. The exhaust gas from the engine is directed by valves 23, 24, to propulsive nozzles 11, 12, or to forwardly extending and tapering manifolds 13, 14. Each manifold feeds a plurality of pairs of injector nozzles 22 located in the passages 15 which are closable by doors 16, 17 operated by jacks 18, 20, through linkages 19, 21. The flat side walls 15a, 15d, of each passage diverge going downwardly, as do the flat front and rear walls. In addition, the front and rear walls and nozzles 22 are inclined rearwardly and downwardly, so that when the nozzles 22 are operative, the thrust produced by the air and gas flow through the passages has a forward component. The two passages also diverge from one another going downwardly as seen in Fig. 4, so that when hovering close to the ground, the flow from the passages sets up a region of high pressure below the fuselage to increase the lift. Gas is tapped by ducts 27, 28 to feed attitude control nozzles located beneath the wing tips and the front and rear of the fuselage. On take-off, the exhaust from both engines is fed to nozzles 24 to provide lift, the aircraft being given a large angle of attack by its undercarriage so that the thrust vector is vertical. The fuselage is then pitched forward to provide a component of forward thrust, but so that the angle of attack is still positive and the wings can develop lift as the airspeed increases. The exhaust of the starboard engine 7 is then fed to nozzle 11, which is inclined so that the resulting horizontal thrust passes through the centre of gravity of the aircraft to prevent yaw moments. Above stalling speed, the exhaust of the other engine is fed to its nozzle 12, to accelerate the aircraft to cruise speed. Thereafter, the starboard engine is shut down, propulsion being by nozzle 12 alone, which is also tilted to reduce the yaw moment, but not so much as nozzle 11, since the tailplane is effective at cruise speed to reduce the yaw. In the transition from forward to hovering flight, a large angle of attack is adopted, to increase drag, while lift is supplied by the ejector passages.

To effect this adjustment, passages 34 in plate 11, Figs. 1, 5 linked to each displacement chamber terminate in openings 35 adjacent a rotary disc 21 driven by an extension 23 of rotor shaft 17, the disc having passages 36, 40 for connecting the passages 34 to the actuating chambers 25, 26 of valve 24 which is actuable to adjust the angular position of valve 3 by connecting the space 53 on one side of each of a pair of shaft-mounted vanes 50 to inlet pressure, and the space on the other side of the vanes to outlet pressure. The passages 36, 40 are positioned so that in operation passage 36 connects a displacement chamber about to change from low to high-pressure to actuating chamber 26, and an instant later passage 40 connects a chamber at high-pressure to actuating chamber 25. Valve 24 will thus be moved to effect advance of valve 3 until the chamber connected to actuating chamber 26 changes over to high-pressure. This will be repeated until any advance (for a pump) or lag (for a motor) is eliminated. As shown in Fig. 2, there are two passages 40a, 40b to permit reversible operation of the machine.
