Title: A method of preparing polymethylalkoxysiloxanes with surface active properties
Inventor: LAUKEVITS JAN JANOVICH
IPC: C08G77/18
Filed: 1964-10-13
Abstract: A methylalkoxypolysiloxane is made by etherifying a silane mixture consisting essentially of Me3SiCl and one or more trifunctional methyl-chlorosilanes, in which the Me/Si ratio is between 1.04 to 1 and 2.82 to 1, with an alkanol containing at least 3 C atoms so that at least all the Si-bonded Cl atoms are replaced by alkoxy groups and subsequently hydrolysing and thermally condensing the etherified product so as to leave some Si-bonded alkoxy groups in the resulting polymer.  Preferably the initial mixture consists of Me3SiCl and MeHSiCl2 and/ or MeSiCl3 having a total Me/Si ratio of 1.04:1 to 1.9:1. Me2SiCl2 may also be added.  Examples 1-19 describe the above preparation of the siloxanes.  Uses.-To prevent pigment floatation in pigmented paints and varnishes, and to enhance the spreading properties of coating resins and varnishes.  In Examples 20 to 24, the siloxane of Example 4 or 8 is added (in solution in xylene) in amounts of from 0.005 to 0.2% by wt. of the composition to (20) a grey enamel consisting of a linseed oil-modified pentaerythritol-phthalic anhydride polyester, white spirit, lead manganese silicate, lithopone and gas carbon; (21) a paint consisting of the polyester of Example (20), white spirit, rutile, lead chrome yellow and furnace black; (22) a paint consisting of a vinyl chloride-vinylidene chloride copolymer, a vegetable oil-modified pentaerythritol-phthalic anhydride resin, butyl acetate, acetone, toluene, titania and gas carbon; (23) a paint consisting of a sunflower seed oil, rosin-modified pentaerythritol-phthalic anhydride polyester, xylene, white spirit, rutile and milori blue; and (24) a styrene-modified maleic anhydride - phthalic anhydride - ethylene glycol polyester, acetone, cobalt naphthenate and cumene hydroperoxide.

Title: Aircraft control mechanism
IPC: G05D1/08
Filed: 1961-11-27
Abstract: 1,004,513. Aircraft controls. KAMAN AIRCRAFT CORPORATION. Nov. 27, 1961 [Dec. 1, 1960], No. 42393/61. Headings B7G and B7W. [Also in Division H1] An aircraft control mechanism comprises a pilot operable member movable in opposite directions to control a motion of the aircraft, and bias control means operable automatically only when the rate of change of the motion is below a given absolute value, for varying the force required to be applied by the pilot to hold the member in a given position. In Fig. 2, the rudder pedals 36 of a helicopter operate, through an hydraulic servo 40, the collective pitch control of an anti-torque tail rotor 38. Feel is imposed by a double-acting spring box 46, the cylinder 48 of which is connected to the pedals, and the piston 50 to the normally fixed output arm 72 of a servomotor 70. A potentiometer winding 60 is fixed to the cylinder and a wiper 62 moves with the piston, or vice versa, so that an analogue signal representing the force applied to the pedals is fed over relay contact 78 to amplifier 68 energizing motor 70. Relay contact 78 is opened by a yaw rate gyro device 74 whenever the rate of yaw exceeds, say, three degrees per second, so that during a deliberate turn, motor 70 is not energized and does not trim out the feel. A continual force applied to the pedals during steady forward flight, however, automatically results in movement of piston 50 so as to trim the zero pedal force position towards the position occupied by the pedals, whereby the feel is trimmed to compensate for changes in yaw trim such as occur on changes in forward speed or during landing

Title: Gas turbine engine
Inventor: PETRIE JAMES ALEXANDER
IPC: F01D25/16
Filed: 1962-11-09
Abstract: 969,579. Gas turbine engines. ROLLSROYCE Ltd. Nov. 9, 1962, No. 42513/62. Headings F1G and F1T. In a gas turbine engine comprising a high pressure turbine on the same shaft as a high pressure compressor and a low pressure turbine on the same shaft as a low pressure compressor the two shafts being concentrically arranged one within the other, a first bearing situated adjacent and supporting the high pressure turbine rotor is mounted adjacent a second bearing situated adjacent and supporting the low pressure turbine rotor, and both bearings are attached to a common static structure, which structure is disposed between the low and high pressure turbines, is fixed directly to an outer casing of the engine, and is protected from the hot turbine gases by nozzle guide vanes which surround the structure. A roller bearing 25 has its inner race 24 on a cylindrical member 23, which is secured to the high pressure turbine disc 18 and hollow shaft 20 by screws 21 and a coupling 22, and its outer race 30 mounted within a flexible member 32. A roller bearing 59 has its inner race 60 supported by a hollow shaft 54, which is secured by a coupling 55 and threaded sleeves 56, 57 to the low pressure turbine rotor discs 50, 51 and its outer race fitted into a cylindrical housing 64 which is secured to one end 67 of the flexible member 32 to form a hairpin-section supporting structure. The flexible member 32 and the cylindrical housing 64 together form a bearing housing which is provided with ring seals 68, 69. The flexible member 32 is connected by a web 34 to a relatively flexible wall 35 of a torus 33, which torus 33 has welded to its radially outer wall 37 a number, for example, thirty, of stiff spokes 38 passing through hollow nozzle guide vanes 44 which may be welded to the torus 33. The spokes 38, which may be forged or cast from nickel based alloys, are secured by screws 42 to a casing 11 having thin adjacent bosses 43 so as to be relatively resilient in these areas and thereby capable of accommodating thermal expansion of the spokes 38. In order to reduce the comprehensive forces in the spokes 38 during expansion, the casing 11 may be stressed to provide a residually tensile force in the spokes 38, or a gas pressure may act on the inner wall of the casing 11. The casing 11 may be surrounded by a by-pass passage of the engine. The static structure formed by the torus 33 is cooled by the air flows indicated by the arrows. High pressure air is supplied to the nozzle guide vanes 44 and to the space downstream of the disc 18 through apertures 76 in the disc 18. In order to balance the axial thrust on the compressor the back of the turbine disc 18 is vented to the exhaust duct (not shown) through apertures 70 in the torus 33 and apertures 71, 72 in the discs 50, 51. The base 17 of each blade 16 of the high pressure turbine is screwed into a bush 17a screwed into the disc 18.

Such tilting of the calcite plate 1 is effected by micrometer screw 27 coupled to the member 17 by pivoted lever 24. The tilt axis I-I is arranged perpendicularly to the principal section of the calcite plate 1 which is carried to a bushing 14 rotatable about an axis II-II in the member 17, means being provided to lock the bushing in its adjusted position In a modification, the member 17 is pivotally mounted between parallel supports upstanding from the condenser housing 19.
