Abstract: A resinous homopolymer of methacrylonitrile or copolymer obtained by polymerizing a mixture of methacrylonitrile and methyl methacrylate containing at least 10 per cent by weight of methacrylonitrile based on the combined weights of the two monomers is mixed with a rubbery copolymer of butadiene-1,3, there being from 65 to 95 per cent of the resinous polymer in the composition based on the combined weights of the resinous and rubbery polymers.  Rubbery copolymers specified are those of butadiene with less than its own weight of acrylonitrile, methacrylonitrile, styrene or methyl methacrylate.  The polymer mixtures may be obtained by mixing aqueous dispersions of the two polymers and then removing the water; alternatively, one polymer in dry form may be added to an aqueous dispersion of the other polymer followed by removal of water, or both polymers in dry form may be mixed together by mastication.  When the rubbery copolymer is prepared in latex form 2-alpha-methylcyclohexyl-4:6-dimethyl phenol may be added thereto prior to coagulation.  The compositions obtained are vulcanizable and may be used for making pipes, pipe couplings, refrigerator parts, panels, helmets, wheels, gears, pulleys and combs.

Title: Ductile chromium-containing ferritic alloys
IPC: C22C38/28
Filed: 1971-06-29
Abstract: 1358747 Chromium-containing ferritic steels E I DU PONT DE NEMOURS & CO 29 June 1971 30419/71 Heading C7A Ferritic stainless steels comprise by weight:- the balance being iron and incidental impurities provided that the titanium content is at least 0À6% when the carbon and nitrogen content exceeds 0À05% and, that the alloys exhibit satisfactory corrosion resistance after welding and/or remain ductile at temperatures above 75 ‹F after welding. Method of Determining Satisfactory Alloy Compositions (a) A number of critical alloy compositions are identified, and the alloys prepared by melting together the required constituents; (b) Each ingot is hot-rolled at 2200‹F, annealed at 1650‹F, water-quenched, cold-rolled, and annealed again at 1560‹F; (c) Samples are welded, and tested to determine the brittle-ductile transition temperature (a range), and as a numerical indication of resistance to corrosion by ferric sulphate in boiling sulphuric acid; (d) The data obtainer is fitted to two sets of mathematical equations, and a computer is used to solve these quadratic equations, the solutions being the brittle-ductile transition temperature and numerical corrosion resistance for any composition falling within the broad range specifier; (e) Graphs are prepared having composition plots for various desirable features, e.g. all compositions appearing on the concave side of a curve or within a closed area in Fig. 3 (not shown) have post-weld ductility at 75 ‹F and good corrosion resistance, while compositions on the convex side or outside a closed area do not possess both these properties, the composition plots being prepared for chosen intervals of chromium and carbon plus nitrogen content, the ordinate and abscissa providing the percentages of titanium and aluminium; (f) Where necessary, the plots are modified to take account of further experimented evidence especially near the origins of the co-ordinates. Thus the properties of specific alloy compositions can be assessed by study of the plots, if necessary using interpolation for intervening chromium, carbon and nitrogen contents. The optional addition of molybdenum appears to improve the corrosion-resistant properties of some of the alloys.

Abstract: 897,720. Testing physical qualities of materials. ENGLISH ELECTRIC CO. Ltd. Sept. 30, 1958 [Oct. 2, 1957], No. 30836/57. Class 106 (2). A mechanical testing machine comprises a movable vibration platform 10a, 10b to support a testpiece, an inert support 18 for the platform, means 24 for imparting motion to the platform and means for arresting this motion by bringing the platform and its support 18 into contact, there being a pre-loaded resilient member 19 adapted to modify the characteristics of the impact shock sustained by the platform. A cam 14 lifts the rod 12 to which the platform 10a, 10b is connected, thus compressing a spring 24. When the peak of the cam is reached the platform falls under the action of the spring 24 and of gravity. The lower part 10b of the platform then hits the support 18 and the prestressed rubber ring 19 is compressed further, thus providing a steady retarding force to the upper part 10a on which the testpiece is mounted. The testpiece then continues to vibrate at its natural frequency. The duration of the retarding force can be controlled by adjusting a nut 20 and by adjusting the height through which the platform falls, this last adjustment being effected by varying the distance between the platform 10b and the cam-follower 13. The machine can be used for repeated impact tests and the effect of gravity can be eliminated by using the machine horizontally instead of vertically as shown. The ring 19 may also be replaced by metal springs and the cam 14 by a lead-screw provided with a trigger mechanism.
