IPC: D03D49/60
Filed: 1937-10-05
Abstract: 498,191. Looms. SHIMWELL, O. and SHIMWELL, D. W. Oct. 5, 1937, No. 26916. [Classes 142 (i) and 142 (iii)] Lays; beat-up motions ; stop-motions, shuttle.-The lay is pivoted to short and long links which swing about two shafts d, e and cause the shuttle track to keep just below the lower line of the warp shed but bring the lay well below such line at the' beat up. The reed part is separate from the shuttle-box parts, the boxes and the reed moving together during the picking period, after which the reed part moves forward at an increased speed to beat-up, unless the shuttle fails to box. As shown in Fig. 1, the shuttle-box parts a are mounted on links b, c and are operated by an eccentric g. The reed part is mounted on links m, n and is operated by a cam t through a lever r and aligned toggle links p, q. If the shuttle does not box the swell a<1> lowers an arm 50 and raises an arm i both on a shaft a<4>. At the beat-up the arm 50 engages a slide block 51 which displaces the stop lever 56 and applies a brake 54, while the arm i engages the catch lever v and through the links w, x, y, breaks the toggle p, q to prevent beatup. As shown in Fig. 5, the reed part is operated through a lever 5 which is pinned at 6 to the long link 7 and pivots about a shaft carried by one 11 of a pair of toggle links 11, 12. Normally the pivots of the lever 5 and link 7 are in line, but when the shuttle does not box, an arm 10 corresponding to the arm i, Fig. 1, carried by the lever 5 engages a lever 16 and through links 15, 18, 14, breaks the toggle 11, 12 to prevent beat-up. As shown in Fig. 8, all parts of the lay are operated from a crank 27, the shuttle parts through a bell-crank lever 25 pivoted at 26 and a link 29, and the reed part through a cam slot 24 in the lever 25 and a link 34 normally held in a higher position than shown by aligned toggle links 40, 39. The Figure shows the parts in position when the shuttle has not boxed, the toggle 39, 40 being broken and the arm 42 operating the stop mechanism 43.

Title: Improvements in or relating to the manufacture of sintered metal articles
Inventor: CLOW COLIN GEORGE
IPC: B22F5/10
Filed: 1959-08-12
Abstract: Sintered metal articles containing voids, ducts or holes are produced by compacting metal powder around suitable formers such as Cd, Zn and In, the formers being so positioned that at least one end of each former is exposed at the face of the compact, and heating the compact at a rapid rate which is just below the rate at which the compact would crack, to volatilise the metal formers. Preferably the rate of heating should not be more than 10 DEG C. per hour below the critical rate which would cause cracking.  The formers may either be arranged in the metal powder with their ends extending to or protruding beyond the surface of the powder or they may be initially completely covered with the metal powder and after compaction the excess powder is removed by machining so as to expose the ends of the formers.  In an example, a mixture of metal powders to form an alloy of 20% Cr, 16,0% Co, 2,35% Ti, 1,35% Al, 0,07%-0,1% C, 0,05% B and the remainder Ni was packed in a floating die with cadmium wires 0,061 inches diameter as formers.  The powder was introduced in layers, the formers being located in position on each layer and then each layer was prepressed at 1 1/2 tons per sq. inch followed by a final compaction at 35 tons per sq. inch.  The ends of the cadmium wires were then exposed by machining off excess powder and the compact was heated in vacuum up to 650 DEG C. at a rate of 160 DEG C. per hour.  The temperature was maintained at 650 DEG C. for four hours and final sintering in vacuum or hydrogen was then carried out at 1300 DEG C.-1325 DEG C. for twenty hours.  Specification 611,466 is referred to.ALSO:Sintered metal articles containing voids, ducts or holes are produced by compacting metal powder around suitable formers such as Cd, Zn and In, the formers being so positioned that at least one end of each former is exposed at the face of the compact, and heating the compact at a rapid rate which is just below the rate to which the compact would crack, to volatilise the metal formers.

Abstract: 759,859. Stamping. ALUMINIUM LABORATORIES, Ltd. Dec. 24, 1954 [Oct. 8, 1953], No. 27746/53. Class 83 (4). A method of deep drawing metal cups comprises producing flat or slightly dished discs having a relatively hard centre and a relatively soft periphery and deep drawing the discs to a depth and a reduction greater than would be possible with identical discs of uniform temper or softness. In an embodiment an age-hardened aluminium blank is annealed around its periphery to a distance of 0.1 to 0.35 of its radius and is then deep drawn in a single operation to a depth sufficient to produce a reduction in excess of 50 per cent. If for a normal draw a hard base is required only, the entire rim can be annealed. After annealing the blank periphery the hard centre part is domed to avoid distortion. The annealed peripheral portion of the blank may be of reduced thickness as compared with the centre portion.
