Patent GB-318075-A (GB)
Abstract: 318,075. Lloyd, G. E., and Electroflo Meters Co., Ltd. Jan. 7, 1929. E l e c t r o magnetic current and pressure meters.-In a moving-coil instrument in which the sensibility is varied by adjusting a magnetic shunt, means are provided for neutralizing the. induced electromotive forces due to the motion of the shunt, so as to prevent contrary deflection of the moving coil. A magnetic shunt 5, pivoted at 6, may be moved relatively to the permanent magnet 1 by means of a cam 7 so as to alter the sensibility of the instrument. On the magnetic shunt 5 is arranged a winding 8 connected in series or in parallel with the moving coil 4. On movement of the magnetic shunt, the coil 8 has induced in it an electromotive force which neutralizes the deflecting effect due to induced electromotive forces in the moving coil 4 or in the metallic former on which it is wound. The winding 8 may alternatively be wound around any part of the magnetic circuit, the magnetic flux through which is changed by movement of the magnetic shunt.

Abstract: A composition suitable for laminating sheet materials comprises a major proportion of a bituminous material, e.g. oxidized asphalt, 1 to 15 per cent. of a copolymer of an aliphatic mono-olefine and an aromatic mono-olefine, and 1 to 15 per cent. of a hydrocarbon oil of a viscosity of 70 to 1,000 S.U.S. at 210 DEG  F.  The aliphatic mono-olefines specified are iso-butylene, iso-pentene and a pentene obtained by dehydrating sec-amyl alcohol, whilst the aromatic mono-olefines are indene, styrene and its homologues, e.g. alpha-methyl styrene, para-methyl styrene, and alpha-methyl para-methyl styrene.  The composition may be dissolved in kerosene, benzene or toluene or emulsified in water. The solid, softened or molten copolymer may be added to the molten bitumen, or the bitumen may be added to the copolymer in a heated kneader.ALSO:A bituminous composition comprises a major proportion of pitch, tar, asphaltic bitumen, wax tailings or an oxidized asphalt, 1 to 15 per cent. of a co-polymer of an aliphatic mono-olefin and an aromatic mono-olefin, and 1 to 15 per cent. of a hydrocarbon oil of a viscosity of 70 to 1,000 S.U.S. at 210 DEG F.  The intrinsic viscosity (which is defined) of the co-polymer is greater than 0.7, and the preferred copolymer is that from styrene and iso-butylene.  The ratio of oil to copolymer should preferably be between 1 and 2 to 1.  The bituminous material may be cut-back or an emulsion.

Abstract: 1,161,934. Pressure-sensitive transfer paper. MEAD CORP. 13 July, 1967 [13 July, 1966], No. 32227/67. Heading D2B. Smudge-resistant pressure-senstive transfer paper is manufactured by coating a paper web with an aqueous mixture of pressure-rupturable capsules containing oily marking substances, a binder such as starch and smudge resistant material in the form of coarse solids such as cellulose fibres Before the web and coating are dried as a whole, the water is evaporated from an inside layer of the coating, away from its surface and next to the web/coating interface by exposing the uncoated side of the web to drying currents of warm air or to contact with heated drums, and/or by heating either or both sides of the web with radiant and/or high frequency dielectric heat. This prevents migration of the binder towards the surface of the coating. Minor amounts of surfactants and/or pH modifiers such as soda ash may be included in the coating composition.

Abstract: 850,060. Controlling aircraft. DOAK AIRCRAFT CO. Inc. Oct. 9, 1958, No. 32266/58. Class 4. [Also in Group XXVI] A convertible aircraft provided with lifting and forward propulsion units which may be simultaneously rotated about a transverse axis to vary the direction of thrust, has means for varying the thrust of the power units in unison or differentially in association with conventional control surfaces such as ailerons 4, 41, and has also jet propulsion means at the tail of the fuselage 1 having jet deflecting vanes operated in unison with the rudder 6 and elevators 5, 5<SP>1</SP>. The conventional control surfaces are operated from the control column 20 and rudder pedals 21 by a cable system as shown in Fig. 1. Each power unit 10 comprises a cowl 10 and a centre boss 11 and fan blades 12 driven through a shaft 71, Fig. 6, from an engine (not shown) in the fuselage. Radial vanes 15 are pivotally mounted in the forward part of the cowl (though, less efficiently, they may be in the rearward part) and they are rotated in unison about their radial axes by an actuator ring 47 operated by a fluid pressure jack 44 connected by conduits 40 to a control jack 38 energised by a bell crank 34 in the aileron control run, so that the vanes 15 in the respective power units may be operated differentially in association with the ailerons. The jacks 44 may be operated by a separate control system incorporating a control jack 39 to vary their thrust in unison for vertical takeoff. The variation in thrust is achieved by adjustment by vanes 15 of the angle at which the airflow strikes the fan blades 12. The mechanism for rotating the power units about transverse axes comprises, at the tip of each wing a bearing housing for a rotatable hollow shaft 60 through which shaft 71 passes, a worm wheel 66 fast with shaft 60 being engaged by a worm 73 driven through bevel gearing 74, 75, shaft 76 and gearing 81, 82 from a common motor 83 whereby the direction of thrust may be varied to effect transition from vertical take-off to forward flight. The efflux from the engine (not shown) passes to a tail pipe 51 and the direction of thrust is varied by vanes 52, 54 operated in association with the elevators 5, 5<SP>1</SP> and rudder 6 respectively. The actuator ring 47 may be operated electrically.
