Title: Descaling method and equipment
IPC: B24B31/02
Filed: 1975-08-06
Abstract: 1472715 Descaling rod J J M ANNEGARN 6 Aug 1975 [7 Aug 1974] 32896/75 Heading B3D A method of descaling a rod 1 comprises forming at least one bend in the rod and rotating the bent portion in an approximately circular path while maintaining it in a space having a distribution of cleaning particles therein. As described, the descaling means 6 for carrying out the method is incorporated in a machine having a stand 2 for supporting a roll 3-of wire 1 to be descaled, the wire being drawn through an eye 4 into a primary descaler 5 having pairs of rolls with certain pairs at right angles to other pairs. The last pair of rolls of the primary descaler feeds the wire into the descaling means 6, the wire also being drawn from the means 6 by an assembly 7 having a drawing roll 8. The descaling means 6 has an enclosure 19, the bottom of which is formed with parallel walls 23 in each of which is a paddle 26 driven by a motor 28, each paddle having blades 27 replaceably secured by pins 29 to blocks 28 attached to the shaft of the paddle. Inlet and outlet openings 30, 31 for the rod are provided in the end walls 21 of the enclosure, the inlet opening consisting of a perforated guide 32 eccentrically coupled to the shaft 33 of an electric motor 34. The outlet opening consists of a guide ring 36 having an inner surface tapering outwardly into the enclosure. The feed and drawing means for the rod are arranged so that as the rod is rotated in the enclosure by the eccentric guide, the centrifugal force causes the rod to take up a bent shape at the same time, the paddles 26 throw abrasive, such as sand or metal shot, into the path of the rod to effect descaling thereof. A rubber baffle may be provided at the outlet to remove abrasive adhering to the rod. In other embodiments, the eccentric guide is at the outlet or both the inlet and outlet may have synchronously driven eccentric guides. The bending and rotation of the rod may be effected by a rotatable tube and a pair of guide rods spread from the tube and each other, the tube having a pair of slots one near each guide, the rod being threaded into the tube out through one slot and bent away and back through the other slot into the tube. The enclosure may be a rotatable drum having slots to carry the abrasive upwardly so as to fall across the enclosure, or the enclosure may be pressurized so that the abrasive forms a fluidized bed, or the floor of the enclosure may be vibrated to throw the particles upwardly.

Title: Improvements in the production of bulked yarns and fabrics containing them
Inventor: APPLETON WILLIAM C
IPC: D02G1/18
Filed: 1957-10-22
Abstract: 869,636. Spinning composite yarns. DELAWARE MILLS Inc. Oct. 22, 1957, No. 32997/57. Class 120(3) High-bulk synthetic yarn is produced from tows of chemically similar continuous artificial filaments of the type which may be rendered " dimensionally unstable" by stretching and which may be relaxed to a relatively stable state with accompanying longitudinal shrinkage by subsequent application of heat e.g. polyacrylonitrile (having an acrylontrile content of at least 80% by weight) or polyethylene terephthalate filaments. Staple fibres formed from one such tow which are stable are blended with at least 30% (of the combined weights) of unstable staple fibres formed from another such tow to form a single sliver which is spun into yarn and the yarn is heated, prior or subsequent to its incorporation in a fabric, to a temperature and for a time such that the unstable fibres shrink longitudinally. The blended yarn may also comprise strength-conferring filaments of different composition from the main constituents. As shown in Figs. 1 and 2, a tow 11, spread and flattened at 10, is stretched between pinch rolls 12 and 13 and heated by plates 14, stapled by apparatus comprising stretch rolls 15 and ribbed breaker rolls 16, 18, condensed and crimped at 19, and the resultant sliver is, continuously or in batches, subjected alternately to vacuum for two minute periods and the action of steam, at 240‹F. for a total of 16-20 minutes, to shrink the fibres. Sliver 22 and a sliver 23, which has been similarly processed but with the omission of the relaxing at 20, are combined into a sliver 24 and spun into yarn 26 which may be knitted by a machine 29 into a fabric 30. Yarn or fabric is heated e.g. by steaming and/or during dyeing, to shrink the unstable fibre content and develop bulk. In a modified sliver preparation, Fig. 3, a tow 32, stretched and heated at 34 to produce unrelaxed fibres therein, is combined with a sliver 33 of relaxed fibres to form a sliver 36 which is consolidated and conveyed by aprons 37, 38, rolled on itself and condensed by a conical roller or scroll 39, then passed by nip rolls 40 to a crimping box 41. Specification 787,157 is referred to.

Title: Improvements relating to the manufacture of copper welded tubing- welded with copper
IPC: B21C37/087
Filed: 1929-11-02
Abstract: 347,723. Coating with metals. BUNDY, H. W., 4815, Bellevue Avenue, Detroit, Michigan, U.S.A. Nov. 2, 1929, No. 33371. Convention date, Nov. 21, 1928. [Class 82 (ii).] In a method of making copper-brazed tubing of steel &c. the tube, together with a supply of copper or brazing alloy having a copper base such as copper-silver, is subjected to a brazing temperature in a reducing atmosphere for a sufficient time to melt the copper and cause it to flow or creep between adjacent surfaces of the tube to braze them together and also to cover the walls of the tube both externally and internally with the copper &c. The tube is made from strip stock which may have been copper-coated on one or both sides or may be plain. The tube may be a double-walled tube, Fig. 1, a butt or lap-jointed tube or a lockseamed tube. The copper 10 may be fed in wire form to the interior of the tube or to the exterior or may be supported from a valve-controlled hopper in the form of a powder made into a paste with a binder. The copper when melted fills the joint and the spaces 11 and flows to the exterior of the tubes by capillary action. Strip metal may be fed from a drum 5a through sectioning rolls 6 and the copper supplied from a spool. The tube passes through an electric furnace 7 to heat the tube to 1100‹ C., the length and temperature of the furnace, and the speed of travel being such that the tube attains its requisite temperature when it reaches the outlet end of the furnace. The furnace is supplied through the tube 9 with a non-oxidizing gas such as hydrogen. The copper is set as the tube leaves the furnace, by passing the tube through a cooling chamber in the form of a water-cooled tank 20 with an inlet controlled bv a valve 22 and an exit 23. The tube is finally cooled by a spray 24 controlled by a valve 27. In an example, for forming a tube having a double wall of stock, a furnace approximately six feet long is used, the temperature therein being maintained at about 2000‹ F. and the tube being passed therethrough at a speed of about two feet per minute. The tube has a diameter of three-eighths of an inch, is made from stock approximately 0À015 inches thick and weighs about one pound per eight-foot length.
