Abstract: 1,223,724. Vinyl alcohol interpolymers. E. I. DU PONT DE NEMOURS & CO. 28 June, 1968 [30 June, 1967], No. 31029/68. Heading C3P. A hydrolysed ethylene/vinyl ester interpolymer comprises 30-65 mole per cent ethylene, 35-70 mole per cent vinyl alcohol and 0-10 mole per cent vinyl ester, the interpolymers being substantially insoluble in an aliphatic alcohol having less than 5 carbon atoms at 0‹ C. The ester may be vinyl acetate, formate, propionate, butyrate, palmitate or stearate. The interpolymer is prepared by (a) hydrolysing an ethylene/vinyl ester interpolymer containing the residues of 30-65 mole per cent ethylene and 35-70 mole per cent vinyl ester such that not more than 10 mole per cent unhydrolysed vinyl ester remains in the interpolymers; (b) forming a solution of the hydrolysed interpolymers in a liquid consisting of a lower aliphatic alcohol; and (c) precipitating from the solution the ethylene/vinyl ester interpolymer. Step (b) may be performed below 150‹ C., and the aliphatic alcohol is methanol, ethanol, n- or spropanol, n-, s- or t-butanol. Step (c) may be performed by cooling to above 0‹ C., the solution prepared in (b) or by adding to water. The interpolymer composition is used as an adhesive in the bonding of lap joints.

Title: Process of manufacturing corrosion-resistant precipitation-hardenable clad aluminium alloys
IPC: B32B15/01
Filed: 1936-11-17
Abstract: In the manufacture of a corrosion-resistant clad aluminium alloy comprising a core of an aluminium alloy containing 2-5 per cent of copper, 0,3-2,0 of magnesium, 0,2-1,5 of silicon and 0,2-1,5 of manganese, and of a facing of a similar aluminium alloy but containing no copper, the clad alloy is subjected to a solution heat treatment and quenching and then to artificial ageing within a temperature range from 130 to 230 DEG  C. until after an initial softening effect particularly high yield points are obtained.  The amount of silicon in the alloys should exceed that required for the formation of the compound Mg2Si.  For an ageing temperature of 150 DEG  C. a suitable period of ageing is 3-10 days and for a temperature of 200 DEG  C. 2-6 hours, but if the alloy has been subjected to cold working prior to the heat treatment the periods of ageing may be reduced.

A turbine comprises a housing having a turbine rotor chamber and an annular fluid supply passage communicating with the rotor chamber around the circumference thereof, one side of the fluid supply passage being defined by an annular plate which is resiliently mounted so as to allow movement of the plate in response to temperature changes. The invention is shown applied to a turbine-driven supercharger assembly which comprises an inward radial flow turbine 72 and a centrifugal type air compressor 44 mounted on a common shaft 26 supported by bearings 28 in a housing comprising parts 12a, 12b, 12c. The housing parts 12a, 12b are secured together by bolts 19, the part 12a providing an air inlet 52, a volute chamber 62 and a discharge outlet 22. Air from the impeller 46 which is provided with straight vanes 50, discharges through a vaneless passage 60 into the volute chamber 62; a baffle 66 is secured to the wall 58 of the passage 60 to project into the chamber 62, whereby flow of air back into the passage 60 is prevented. The housing part 12c provides an inlet portion 24 for hot gases which is divided into two portions 96, 98, the portion 96 supplying gases to a chamber 84a and the portion 98 supplying gases to a chamber 84b, the chambers 84a, 84b being separated by walls 100, 102. The gases from the chambers 84a, 84b are directed on to the turbine rotor 74 by nozzle vanes 88 and the exhaust gases discharge from the turbine through an outlet duct 80. The nozzle vanes 88 are supported on a ring 90 which forms one wall of the turbine supply passage, the ring being formed with an axially-extending flange 90a and being urged towards the left as shown in Fig. 2 so that the nozzle vanes 88 bear against the wall 78a of the housing part 12c by means of a ring-shaped spring member 94. The member 94 is formed with tongues 94b, 94c which as seen in Fig. 4 bear against the ring 90. The housing parts 12b, 12c are formed with flanges 12d, 12e which have inclined faces, the parts being clamped together by a clamping band 20 which engages the inclined faces, provision being made for adjusting the relative angular positions of the parts 12b and 12c. Lubricating oil is supplied to the bearings through ducts 33, 34, 36 and discharges through an outlet 40.

[Also in Division H1] A fuze for spinning projectiles comprises a pyrotechnic chain having at least a primer and detonator (not shown), a part 11 of the train being carried by a movable member 10 responsive to centrifugal force for shifting the part 11 from a safety position into an active position in alignment with the rest of the train, a releasable lock 27 for locking the member 10 in its safety position, and means responsive to centrifugal force for releasing the lock, the release means including a mass 39 arranged to effect a rotation and translational movement respectively about and along its intended direction of travel under the action of the centrifugal force. The mass 39 is in the form of a nut engaging a helical thread 36 formed on the outside surface of a fixed hollow tube 29. The lock 27 is integral with a displaceable rod extending through the tube and terminating in a washer 35. A displaceable lock 40 secures the mass 39, and bolts 20 and 21 responsive to centrifugal force extend into notches 16 and 17 formed in the movable member 10. Upon launching a projectile fitted with the fuze, the bolts 20 and 21 are withdrawn from their respective notches and the member 10 is displaced by a distance determined by the width of a notch 26. Displacement of the member 10 by this amount permits pivotal movement of a lever 44 and thereby release of the lock 40 under the action of a spring 42. The released mass 39 then moves along the tube 29 to engage the washer 35 and lift the lock 27 out of the notch 26. As the member 10 moves to align the part 11 with the remainder of the pyrotechnic train, conductors 50 on either side of an insulating plate 40 engage electrical contacts 51. Teeth formed on the contacts engage grooves 52 in the conductors to aid retention. The contacts 51 form part of a circuit for a target detecting unit and a mechanism for correcting the projectile trajectory by the lateral projection of a subsidiary projectile.
