Title: Improvements in warp knitted fabrics and to methods of and machines for producing the same
IPC: D04B23/00
Filed: 1957-02-11
Abstract: 849,454. Knitting. SWANN & CO. Ltd., A. W., and BOLTON, W. Jan. 30, 1958 [Feb. 11, 1957], No. 4582/57. Class 74 (2). A warp-knitted fabric is patterned by the deliberate production therein, at predetermined dispositions, of the effects (termed " false spots ") produced by abnormally highly-tensioned or slack warp ends. The false spots are provided by periodically increasing or decreasing the tension of selected warp ends, to produce, each time, a local bunching of the wales and so knops fs and associated eyelets o, or a local snarling e<SP>2</SP> of the slackened yarns. In a two-bar fabric, the back guide-bar may be halfset and the front bar fully set; and, of the front bar yarns, alternate pairs may be manipulated to produce the false spots. In the two-bar fabric of Fig. 5, the front bar yarns produce the warp chains cs which are tied together by warp ends e laid in by the back bar; and the false spots fs<SP>3</SP> are produced by periodical slackening of ends e. The resultant raised parts may be brushed to provide a fleecy finish. In the fabric of Fig. 6, the tension of alternate pairs of front bar warp ends is periodically increased to produce false spots f5<SP>2</SP>; and, in addition, by varying the lapping of that bar, there may be provided stripes f, or diamonds, squares, or other geometrical designs. The false spots may be disposed to provide floral designs, all-over effects, mock intarsia patterns, geometrical designs, or designs such as those used in embroidery or lace. The slack loops formed in recovery of normal run-in after extra tensioning of selected ends, serves to produce shadow effects. In the arrangement of Figs. 7 and 8, the tension on warp ends passing under and over tension-bars 6, 5, is increased to or above the normal value, according to pattern requirements, by the raising of members 13, through hooks 13b of which pass individual warp ends or small groups thereof. The members 13 are raised by lugs 28 on a pattern chain 26, driven from the main pattern drum, the lugs acting through bell-crank levers 30 and cords 31 on spring-returned reciprocatable rods 18, each of which is connected with a member or members 13 through a pin or pins 17 and cords 15 passing over pulleys 19. Alternatively, selected yarn ends may be supplied from reels or bobbins, instead of from the warp beam, and the rotational speed of these reels or bobbins controlled.

Title: Can arranging conveyor mechanism
IPC: B65B35/44
Filed: 1948-02-19
Abstract: 647,980. Endless-chain conveyers. CHISHOLM-RYDER CO. OF PENNSYLVANIA. Feb. 19, 1948, No. 4964. Convention date, May 23, 1944. [Class 78 (i)] Cans are spaced into groups as they are fed to an elevator, which conveys the groups to a predetermined height, where the cans of each group are discharged into a plurality of lines equal to the number of cans in the group. Shafts 31, 36 are journalled in side plates 20, 21 which have slots 30 at their upper ends for vertical adjustment of bearings 32 of shaft 31. A pair of endless chains passed around sprockets 34, 35 on shafts 31, 36 are joined at intervals by rods 43 to provide spaces slightly greater than a can diameter. Shaft 31 is continuously rotated by a motor, not shown. A pair of vertically disposed U-shaped guides 40, Fig. 10, guides the chains on the conveying run. Cans are fed into a shoot 51 hinged at 52 to the framework and pass to a flexible strip of fabric 53 which is supported by curved guides 56 and hinged at one end 54 while the other end is supported by springs 60 adjustably secured to the framework for varying the tension. Rods 43 engage between the cans while the flexible strip 53 resiliently supports cans which may be forced down owing to irregular feed causing them to fall vertically below a rod 43. The cans are spaced into groups during feeding by a pair of cams 70, Fig. 12, which are secured to the shaft 36 and proportioned so that after a predetermined number, e.g. six, of cans has passed it blocks the next space between rods 43, preventing entry of a can, the following space receiving the first can of the next group. The groups are elevated between plates 27 and 66, Fig. 12, until each can is opposite one of the discharge shoots which consists of lips 73 from which extend flexible plates 74 receiving the ends of angle iron tracks 75. Plate 27 terminates at the first shoot and a pair of doors 81, Fig. 7, is placed above it. Guide plates 79 are situated at the sides of the discharge openings. On a group of cans reaching the position of alignment with the openings, a series of push plates 107, Fig. 3, pivotally mounted on shafts 106 in the frame are operated by a pair of cams 99 secured to the shaft 36 which through follower rollers 100 raise a pair of bars 97 slidably mounted in brackets 98, Fig. 1, on the outside of plates 20, 21. Outwardly projecting pins 96 on bars 97 engage levers 87, 88 pivoted at 91 so that their remote ends 89, Fig. 7, move vertically downwards in inclined slots 85, 86, Fig. 7, in the doors 81. This forces the doors apart. At the same time inwardly projecting pins 108, Fig. 3, on bars 97 engage arms 105 secured to the shafts 106, causing the push plates 107 to eject the cans. A roller 110 may be placed against the flexible member 53, Fig. 1, to ensure the cans passing into the space between plates 27 and 66. The apparatus may be used in an inclined position, in which case push plates 107 may not be required.

Patent GB-601975-A (GB)
Title: Improvements in the production of high strength malleable iron alloy castings
IPC: C21D5/10
Filed: 1945-02-28
Abstract: In a process for producing malleable iron alloy castings from low alloy white cast iron containing one or more metals capable of inhibiting carbide decomposition viz:- chromium, manganese, molybdenum, nickel, vanadium, tungsten, the total carbon content is reduced by a decarburizing heat-treatment to an amount which if uniformly distributed would give a carbon content in any part of the casting equal to that required in a low alloy wrought steel, the casting then being submitted to a deep diffusion annealing under non-oxidising conditions within the temperature limits for solid solution i.e., between Ac3 and the solidus line-until a homogeneous structure with uniform carbide distribution is attained.  The temperature for the diffusion annealing is preferably higher than that for decarburizing, and a normalising treatment may follow.  The products of the treatment may be hardened, tempered or austempered. In an example, a low alloy cast iron containing 2.7 per cent C, 0.6 per cent Si, 1.5 per cent Mn, 0.06 per cent P, 0.03 per cent S, 0.9 per cent Cr, 0.4 per cent Mo was decarburized at 1,000 DEG C in an oxidising atmosphere until the carbon content was reduced to 0.4 per cent, followed by annealing in a neutral atmosphere at 1,150 DEG C. After normalising, hardening at 850 DEG C, and tempering at 650 DEG C, for 3 hours mechanical properties comparable to those of a low alloy steel of the same composition were attained.
