IPC: C21B5/00
Filed: 1968-12-12
Abstract: 1,257,320. Tuyeres; burners. COMPAGNIE FRANCHISE DE RAFFINAGE, and DE WENDEL ET CIE. 12 Dec., 1968 [13 Dec., [1967; 30 April, 1968], No. 59068/68. Headings F4B and F4T A blast furnace tuyere 1, in which is effected complete combustion of a supplementary fluid fuel added in a substantially lateral direction to the axially flowing air blast, includes at least one fuel injection tube 4, or other fuel inlet orifice, which discharges fuel into or adjacent the diametral plane of a neck 3 in the tuyere wall 2a, to form a fuel/air mixture which flows towards the downstream end 2 of the tuyere, and is ignited and forms a stable flame in the turbulent wake immediately downstream of an obstacle 6 inserted into the end of the tuyere. The obstacle 6 may comprise one or more solid or hollow tapering bodies (Figs. 1 to 4, not shown) and may be fluid cooled. In modifications (Figs. 6 and 8, not shown) the obstacle may be longitudinally extended to the plane in which the supplementary fuel is injected, and by providing there a reduced tuyere crosssection eliminates the need for a neck such as 3. In such a case the upstream end of the obstacle may be provided with-the fuel inlet orifices. A wall 12 may be mounted within and spaced from the tuyere wall 2a to shield the latter from the heat developed by the fuel combustion. In another modification (Fig. 7, not shown) jets of air, steam, inert gas or vapour, or fuel/air mixture jets are introduced near the downstream end of the tuyere to provide an aerodynamic obstruction in place of the solid or hollow obstacle, in the turbulent zone of which jets the supplemental fuel/air blast mixture burns with a stable flame. An expansion chamber may be arranged at the downstream end of the tuyere (Fig. 9, not shown). Formulµ to establish the correct position of the obstacle in the tuyere to give a stable flame under various operating conditions are given In an alternative form of tuyere, Fig. 11, the obstacle is formed by a projection 35 of the water cooled inner wall at the downstream end of the tuyere. Preferably the cone angle of the conical portion of the projection is between 10 and 30 degrees, and the surface area of the base of the cylindrical portion of the projection is not greater than 30% of the total cross-sectional area of the tuyere. The fuel is added to the air stream through an upstream fuel injection tube (not shown), the projection 35 causing a recirculatory flow of the fuel air mixture in zone 40, an electrical resistor 39 initiating ignition -to give a stable flame formation. The cooling circuit for the projection may be independent of or common with that of the remainder of the tuyere. The added fuel may be petroleum oil, fuel oil, natural gas or coke oven gas.

Title: Bottom stop method and machine for sliding clasp fasteners
Inventor: PERLMAN MORRIS
IPC: A44B19/60
Filed: 1968-12-19
Abstract: 1,254,319. Making staples; bending; punching; shearing. M. PERLMAN. 19 Dec., 1968 [26 Dec., 1967], No. 60388/68. Headings B3A, B3E and B3W. [Also in Division E2] A machine for inserting staple type end stops in sliding clasp fasteners forms the end stops from a metal strip and inserts them in the sliding clasp fastener in a single operation. The metal strip 28 (Fig. 1) is fed intermittently by stationary grips 30 and moving grips 32 to a punch 78, 84. The moving grip 32 is operated by arm 36, and a wheel 40 which bears on cam surface 42 of ram 44. Ram 44 slides in channel 46. The ram is reciprocated by means of link 52 which is eccentrically pivoted on shaft 56 which in turn is driven by motor 64 via belt and pulley system 62, 58, 57. Drive plate 70 (Fig. 5) is connected pivotally to shaft 56 (Fig. 1) by link 50. The drive plate carries driver 74 (Fig. 5) and punch 78, the driver slides between blocks 80 on ram 44. As shaft 56 rotates anti-clockwise starting with pin 54 at 12 o'clock, the driver plate 70 is forced downward causing punch 78 and driver 74 to move downward. This causes the metal strip to have holes slotted in it, and the staple to be severed from the strip. Further downward movement causes the staple to be bent on slide 90 carrying a coil 94. When pin 54 reaches 9 o'clock the ram 44 moves downwards causing the slide 90 to be moved against the action of spring 116, from beneath the staple, and the staple to be forced down. The ram then forces the staple legs through the sliding clasp fastener stringer and against anvil 122 (Fig. 1) bending the legs over. The sliding clasp fastener chain moves past the ram head intermittently. Its motion is controlled by a blade 132 (Fig. 11, not shown), connected to spring-loaded arm 134 (Fig. 1), which operates a solenoid 138 controlling the sliding clasp fastener chain drive means. Blade 132 acts as a locating stop for the sliding clasp fastener chain and is disengaged by the downward movement of ram 44. Two types of end stop may be used, both are characterized in that they do not produce a continuous cut through the stringer top along their entire lengths (Figs. 9 and 13, not shown). Specification 3,445,912 is referred to.
