Title: Improvements in or relating to Wire-Drawing
Inventor: ROWE HERBERT ALFRED
IPC: C21D9/62
Filed: 1967-02-17
Abstract: 1,152,605. Drawing. PIRELLI GENERAL CABLE WORKS Ltd. 15 Feb., 1968 [17 Feb., 1967], No. 7572/67. Heading B3P. Wire e.g. copper, aluminium, is passed from one drawing die or die sequence to a following die via an annealing zone. The wire 9 is passed through a sequence of drawing dies, around pulleys 7a-c and on to a capstan 16, from where it passes upwardly to a contact sheave 17. On passing back down to an insulated idler sheave 18, back up to an insulated idler 19 and to a contact sheave 20, the wire is preheated by passing an electric current through it. The wire is also electrically heated between sheaves 20 and 21 and is passed through a steam atmosphere in a tube 23 into a coolant bath 24. After annealing, the wire is drawn through a second sequence of dies not more than 90% reduction in area.

Abstract: 727,668. Scoop arm load handling machines. BROCKHOUSE (SOUTH AFRICA), Ltd., J. March 24, 1952, No. 7592/52. Class 78 (3). [Also in Group XXI] In an overthrow loader, the shovel is constrained to move along the path shown chain-dotted by cam tracks 25, 29 secured to the side plates 13, and rollers 50, 56, mounted on the rocking arm 41, when a chain 60 is wound on and off a winch drum 19 driven by an air motor 20. The cams are each constructed from a number of separate short sections, any one of which can be replaced if worn. A spring buffer 63 is provided to cushion the discharging movement of shovel, whilst for digging the shovel rests against an abutment plate 65. The shovelling mechanism is mounted on a top deck 11 which is rotatable about a vertical pivot 9 for side shovelling but is normally locked centrally on the lower structure 2 by a bolt (not shown) passing through aligned holes 80, 79. When the loader is used for side shovelling, the upper deck is automatically re-centred during each upward movement of the shovel by the engagement of one of the arms of a V-shaped cam 66, which is secured to the structure 2, by a roller 77 which is rotated clockwise with a shaft 69, journalled in the upper deck 11, when the roller 56 engages an arm 72 also secured to shaft 69. A spring 81 is provided to retain the parts in a centring position, and a second arm 71, secured to shaft 69, is engaged by roller 56 on its return movement to reset roller 77.

Abstract: 978,375. Nuclear reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Feb. 26,1963 [March 1, 1962], No. 7729/63. Heading G6C. Movement of the fuel elements 4 with fluid flow along the vertical coolant channel 1 of a fluid cooled nuclear reactor, which flow is upwards in the direction of the arrows f is prevented by means of a stepped plug 8 sitting in a portion of the channel 1 of enlarged cross-section, the area of the bottom surface of the plug being slightly less than that of the cross-section of the channel 1 while the area of the top surface is greater, a by-pass 10 extending from the bottom of the channel 1 near the cooling fluid entry conduit 2 to the top of the channel 1 above the top surface of the plug 8. The by-pass 10 enables the pressure in the channel 1 below the fuel elements to be exerted on the top surface of the plug 8 and, since the area of this surface is greater than the cross-sectional area of the channel 1, the fuel elements 4 remain in position, a finger 9 at the bottom end of the plug 8 engaging the top fuel element 4. Stop means (not shown) are provided in the channel 1 below the fuel elements 4 to limit their downward movement when they are not supported by the flow of cooling fluid.

Title: Improvements in coke oven batteries
IPC: C10B21/10
Filed: 1946-03-12
Abstract: 609,385. Coke ovens. WILPUTTE COKE OVEN CORPORATION. March 12, 1946, No. 7745. Convention date, June 13, 1945. [Class 51(ii)] In an underjet regenerative coke oven battery in which the lean gas regenerators and the air regenerators are connected to each of the heating wall flues by branches 61, 62 and a common throat 57, the throat is not less than ten inches long, and preferably not less than thirteen inches long, the divergence of the side walls from the top opening is less than ten degrees, and the walls are rounded at the top opening, the radius of curvature being not less than one half an inch. The cooking-chambers, being wider at the coke side of the battery than at the pusher side, it is necessary to arrange for the gas and lean air supply to the flues to increase progressively from the pusher side to the coke side to correspond with the progressively increasing mass of coal to be coked at different cross sections of the coking-chambers. The sides of the throats 57 are therefore arranged at a progressively decreasing divergence from the pusher side to the coke side as shown in dotted lines, the areas of the throat tops being thus progressively increased. A variation of this arrangement is necessitated by the relative large radiation losses from the flues at the pusher and coke ends of the battery, the throat openings being increased at these regions to provide a compensating additional supply of lean gas and air. The invention is described as applied to a battery having transverse rows of flues divided into two groups to operate reversibly with corresponding transverse rows of regenerators, each regenerator row comprising two exterior and one interior regenerators. The flue group at the pusher side comprises two sets of eight reversible flues joined by a horizontal top flue, and the group at the coke side comprises sets of seven and six flues joined by a horizontal top flue. The throats 57 are designed to take account of static pressure variations in the horizontal top flues, and a table of suitable throat dimensions is given. Provision is made for firing the battery with coke oven gas, in which case all the regenerators would be used for preheating combustion air. The usual basement space contains known reversing arrangements and the air supply is through the basement which is connected to the atmosphere by an air channel running the whole length of the battery, beneath the bench on the coke side. A blower may be provided and a filter may be arranged in the channel.
