Title: Thermoplastic compositions and method for their production
IPC: C08L9/02
Filed: 1961-11-06
Abstract: A thermoplastic composition of high impact strength is made by blending a copolymer of from 90 to 60% by weight of styrene and from 10 to 40% by weight of acrylonitrile with a substantially inelastic copolymer of from 80 to 55% by weight of butadiene and from 20 to 45% by weight of acrylonitrile in such an amount that the composition contains from 5 to 45% by weight of said inelastic copolymer. The mixing of the two components can be effected by conventional methods, for instance by masticating the separately produced dry components on a calendar or in a Banburry mixer at a suitable temperature e.g. 150 DEG C.; other ingredients such as fillers, dyestuffs and stabilizers may be incorporated. The components may also be prepared in the form of emulsions and blended as latices, the mixture being dried according to conventional methods. The styrene copolymer may be prepared by suspension or bulk polymerisation. Mixtures of the two components may also be prepared by dissolving one of the copolymers in the monomer of the other component and polymerising the mixture. One of the two components may be first emulsion-polymerised, said emulsion may then be added to an emulsion of the monomer of the other component, and the polymerization may then be continued to completion.  The butadiene-acrylonitrile copolymer may be prepared in the presence of a mercaptan polymerization modifier and also, if desired, in the presence of a small amount of cross-linking agent e.g. divinyl benzene.

Title: Improvements in and relating to short or vertical take-off aircraft
Inventor: CREASEY RAYMOND FREDERICK
IPC: B64C29/00
Filed: 1960-11-18
Abstract: 979,221. Aircraft supported on the ground by gaseous cushions. ENGLISH ELECTRIC CO. Ltd. Nov. 17, 1961 [Nov. 18, 1960; Aug. 8, 1961], Nos. 39834/60 and 28683/61. Headings B7G, B7K and B7W. An aircraft has nozzles for producing a gaseous cushion enclosing curtain on its underside, the vertical thrust associated with the nozzles being less than the vehicle weight, and energy-storing means for increasing the height of hover above the maximum steady value. In Fig. 3, a plurality of discrete nozzles 16 are provided in the underside of a fairing 15 of the fuselage, the side nozzles having deflectors 17 for producing a forward or reverse component of thrust. Auxiliary pitch and roll control nozzles 7, 8 and 13 are provided. Full span flaps 11 and full span blowing slots 12 located just above the wing leading edge, can be used for high lift. Cold air may be blown through slots 19 over the main undercarriages 18, to cool them when the cushion is in use. In the case of a delta-wing aircraft, the nozzles may be arranged along the edge of the delta planform. Stored compressed gas may be released through the nozzles 16 to give added initial vertical thrust. For take-off, the nozzles are used so that their jet reaction thrust together with the lift from the enclosed cushion exceeds the aircraft weight, so that the aircraft rises initially to a height above the steady hovering height. During this rise, the aircraft is accelerated by jet propulsion units 14 to a speed at which the aircraft is wingborne, the high lift flaps 11 and slots 12 being used. In Fig. 2, the wing has a central flat-bottomed rhomboidal section 110, and outboard sections 10 (one shown) set at a dihedral. Flaps 111 and slotted flaps 11 are provided. Gas turbines 113 in the nose, and 114 in superposed pairs in the wings, supply compressed air to drive turbines of propulsive ducted fans 112 and curtain forming ducted fans 115, the latter having inlets and outlets which can be faired by louvres in forward flight. The curtain is continuous, but may be open at the front beneath the fuselage. The ducted fans may be shaft driven by engines 113 and 114. The ducted fans 112, Fig. 4, blow air through the slots formed by flaps 11 when lowered, to form a jet flap arrangement. For take-off the ducted fans 115 are spun up at zero pitch, and flaps 11 and 111 are lowered, the latter through, say, one hundred degrees, to assist the fan effluxes to spread and form the required curtain. Fans 115 are then set to a coarse pitch, so that the curtain and cushion are formed, and as in the embodiment of Fig. 3, the aircraft rises to a height of, say, 60 feet, being above that which can be maintained by the curtain and cushion alone. During this rise, the fans 112 are driven, to accelerate the aircraft to wingborne speed. Thereafter, flaps 11 and 111 are raised, and fans 115 shut down and their inlets and outlets faired off. Some of the engines 113 and 114 can also be shut down, the remainder driving fans 112.

Abstract: 1459820 High pressure apparatus NATIONAL RESEARCH DEVELOPMENT CORP 27 Nov 1973 [29 Aug 1972] 40032/72 Heading B1X Apparatus to compress material has only two anvils mounted to converge along a common axis and a plurality of pressure blocks which may be arranged between the anvils and around the material so that they totally enclose it, convergence of the anvils causing the blocks to move against each other so that they reduce the volume of the enclosed material without changing its shape. As shown, anvils 1, 4 each has a recess 3, 6 in its face defined by three walls 7, 8, 9 and 12, 13, 14. The anvils are offset so that the angle between two walls of one recess coincides with the median of a wall of the opposing recess. Six pressure blocks 15 to 20 enclose a cubic space 21, which contains the substance to be subjected to pressure, e.g. in the manufacture of diamonds, graphite, enclosed in pyrophyllite. Each pressure block has two square and four rectangular faces, in each case one of the square faces forming a side of the cubical space 21. Convergence of the anvils causes the blocks to slide so that the space 21 becomes smaller but remains cubical.
