A polyblend comprises (A) a matrix of an interpolymer consisting to the extent of more than 50% by weight of a monovinylidene or monovinyl aromatic hydrocarbon and an unsaturated nitrile; (B) a first graft copolymer having a rubber substrate and a superstrate of an interpolymer consisting to the extent of more than 50% by weight of a monovinylidene or monovinyl aromatic hydrocarbon and an unsaturated nitrile, said first graft copolymer having an average particle size, based on number average, of 0.8 to 2.0 microns, at least 75% of the particles having a size within the range 0.7 to 2.1 microns; and (C) a second graft copolymer having a rubber substrate and a superstrate consisting to the extent of at least 50% by weight of a monovinylidene or monovinyl aromatic hydrocarbon and an unsaturated nitrile, said second graft copolymer having a number average particle size of from 0.01 to 0.25 micron, at least 75% of the particles having a size within the range 0.005 to 0.30 micron, said first and second graft copolymers comprising 1 to 70% by weight of the poly blend and said second graft copolymer comprising from about 70 to 97% of the total weight of said graft copolymers. Additional interpolymer of type (A) or ungrafted rubber may be incorporated in the poly blend to provide the required amount of matrix. Preferred rubber substrates contain at least 50% of a conjugated diene. In Examples 1 to 5, graft copolymer (B) is formed by dissolving a butadiene rubber in a mixture of styrene and acrylonitrile, polymerizing the monomers to 30% conversion and completing polymerization in aqueous suspension; graft copolymer (C) is formed by grafting styrene and acrylonitrile on to a butadiene-acrylonitrile rubber latex in aqueous emulsion and the graft copolymers are blended together, with a styrene-acrylonitrile copolymer in some cases. In Example 6 a graft copolymer of particle size 0À13 micron comprising styrene and acrylonitrile grafted on to a butadiene-acrylonitrile rubber and a graft copolymer of particle size 0.05 micron comprising styrene and acrylonitrile grafted on to a butadiene-styrene rubber are prepared in aqueous emulsion, the latices are cocoagulated and the resulting crumb is blended with graft copolymer (B) and a copolymer as in Example I.

Title: Improvements in or relating to method and apparatus for applying soldering material to a workpiece
IPC: B23K1/16
Filed: 1955-05-06
Abstract: 782,602. Soldering; bending; shearing adjuncts. GARDNER-DENVER CO. May 6, 1955 [May 7, 1954], No. 13172/55. Class 83 (4). In applying soldering material to a workpiece the material is fed past a point at which a bending moment is exerted over a predetermind length of the material to give a curvature thereto, so that it passes about a workpiece located adjacent the point and the material is cut after the said length is disposed about the workpiece. A soldering wire 20 is fed by rollers 21, 22 through a bore 17 in a plate 13 to strike at a point X, Fig. 2, the sloping surface 15 of a block 14 slidable between the plate 13 and a support 18 to form with the aid of a groove G on the plate 13 a loop 20a which surrounds a workpiece 23 held in cradles 26, 27, Fig. 1, mounted on adjustable arms 24, 25. A small loop 20b is formed if the block is moved farther forward. When the loop is complete the block 14 is moved forwardly so that an edge of the surface 15 shears the wire projecting from the bore 17. The block 14 is secured to a member 32, Fig. 3, sliding in a channel 33 and a lever 34 coupled to the member 32 and spring urged to bias the member 32 against an adjustable stop 39 is periodically acted on by a cam 40, the speed of rotation of which may be related to that of the feed rollers, to move the block 14 forwardly. The workpiece may have an annular groove into which the solder ring is fitted and loops of other than circular shape may be formed by changing the position of the block 14 during forming.

Title: Improvements in and relating to devices for reducing noise of impact in valve-actuating and other mechanism and methods of making such devices
IPC: F01L1/16
Filed: 1920-05-13
Abstract: 168,115. British Thomson-Houston Co., Ltd., (General Electric Co.). May 13, 1920. Cased forms ; fluid-pressure engines. - A cushion or pad for reducing the noise and shock on impact between contacting parts, more particularly applicable in the valve-gear of engines for motor-vehicles, comprises a body of spinnable textile fibres 18, Fig. 7, highly compressed within an open-ended casing 17 and forming the striking point of a tappet rod, valve-lever or other member. The fibres may be of asbestos, cotton, or a mixture of the two. In making the pad, a mass of fibres 15, Fig. 3, is supported, for example, from the tail-stock 12 and head 13 of a lathe, and twisted until the metal casing 14 can be slipped over it. The twist is then released, and the tube passed through successive dies of decreasing size, or swaged in two or more stages, the diameter being reduced by about # to <5>/32 of an inch at each operation. The tube is then cut into lengths as required, finished to a convex shape, as shown in Fig. 3, and mounted in the socket 31. The material has a limited amount of resiliency, and will absorb shock; it can be machined by ordinary methods, and the wear on the striking surface is about the same as that of steel.

Title: Improvements in the production of n-gamma-oxoalkyl derivatives of amino phenols or naphthols
Filed: 1951-06-05
Abstract: Aromatic hydroxyamino compounds substituted on the nitrogen by 1 or 2 g - oxo-alkyl groups are obtained by the reaction of aminophenols or aminonaphthols having one or both aminohydrogens free with a - b -unsaturated ketones.  In examples, mamino-phenol reacts with 2 mols. vinyl methyl ketone to give N:N- di (g - oxobutyl) maminophenol, and 1:2 aminonaphthol reacts with isopropenyl methyl ketone to give the corresponding N:N- di (g - oxoisopropyl) 1- amino- 2- naphthol. Other aminophenols specified include o and p-derivatives, aminocresols, aminoxylenols and N- monoalkyl derivatives of all these compounds, and as ketones, vinylethyl, propyl and butyl ketones.  Equivalent quantities of reactants produce the monog - oxoproduct with the unsubstituted amino group, while 2 g - oxoalkyl groups result when 2 mols. of the ketone are employed as above.

A fixed frame b carries plates or insulated wire of soft iron in circuit with a coil c<1> mounted where convenient and enclosing the magnetic needle c<2>. Two or more rotating coils may be mounted one above the other with their axes at right-angles. Fig. 2 shows three coils so mounted in inner casings a within an outer casing A secured to the detecting- vessel by rods A<1>. The lowest casing a contains a fixed frame and coil similar to b, and one rotating coil d, whilst the middle casing a contains only a rotating coil e, the two together being equivalent to the instrument shown in Fig. 1.

Abstract: 1395321 Producing polygonal section workpieces TURRET TOOLING Ltd 8 May 1972 [7 May 1971] 13672/71 Heading B3T In a method of producing one or more flat surfaces for example multiple sided polyhedral workpieces by effecting relative rotation between a workpiece and an annular cutting tip embracing the workpiece and having one or more inwardly extending cutting tools, curvilinear translational components of motion are produced between the workpiece and the or each cutting tip, the components combining to provide a substantially linear locus at their intersection thereby forming a flat surface(s) on the workpiece. The size and number of flat surfaces produced are dependent on (i) the ratio of speed of relative rotation between the cutting tool and workpiece, (ii) the number of cutting tips on the tool, (iii) the radius of the workpiece in relation to the radius of the or each cutting tip edge from the axis of rotation of the cutting tool. In the embodiments shown in Figs. 1 to 3 both the workpiece 70 and the cutting tool are rotated. In Figs. 5 and 6 the workpiece is stationary and the cutting tool 95 is rotated about its axis 101 and simultaneously about the axis 102 of the workpiece, the cutting tool thus performing an orbital motion about the workpiece, the drive for the cutting tool being in the form of epicyclic gearing.
