Abstract: 776,828. Winding wires. ENSOR (PATENTS), Ltd. May 27, 1955 [March 4, 1954], No. 6395/54. Addition to 697,340. Classes 120 (2) and 142 (1). In a machine for winding a number of wires from bobbins 14 to a reel, the reel is reciprocated during winding so that it moves in one direction while one layer is being wound and in the opposite direction while the next layer is being wound. The machine uses .the jockey pulley arrangement 31 described. in the parent Specification, the metering wheel thereof having, in the present invention, a non-slip surface. This surface may be provided by roughening or knurling, by covering the wheel with carborundum or with a grit impregnated cloth. Alternatively when ferrous wires are being wound, the metering wheel may be magnetized, preferably electromagnetically. Each wire passes over a tension roller 21 connected to a brake band round the corresponding supply bobbin. A bar 59 is arranged above the wires as they pass between pulleys 53, 55 so that if a wire breaks it contacts the bar and a relay circuit cuts off the motor. The wires pass round the metering wheel 63, over pulleys 68- 70 and on to the reel. The reel is driven from a motor 75 by belts 85, 89, a reversing gear (Fig. 8), a variable-speed pulley 99, and a belt 99a. The variable-speed pulley drives one 93 of two centres holding the reel and which are mounted on a carriage traversed and reversed by the gear shown in Fig. 8. The reversing gear has a pulley 101 driven by the belt 89 and includes bevel pinions 106, 107, and a clutch 110A, 111A whereby the drive from the pulley 101 is connected to a screwed shaft 121 via bevelled pinions 110 and 119, or 111 and 119. Rotation of the shaft 121 causes a member 122 to be traversed, and through a pin 133, the carriage and the reel are traversed. The gear is reversed by an arm 124A engaging stops 129, 130 at the ends of its travel and moving a rod 126. The rod has a member 132 rigid therewith and connected by a lever to a fork operating the sliding member 112 of the clutch. A spring loaded ball 115 keeps the clutch engaged. A stop and start switch is provided for the motor and a main switch is also provided. To facilitate the commencement of winding a handwheel 138 is mounted on the shaft carrying the centre 93.

Patent GB-807925-A (GB)
Title: Improvements in or relating to the production of stabilized austenitic cast steel
IPC: C21C7/00
Filed: 1956-03-01
Abstract: In the production of stabilized austenitic cast steel the formation of carbide flakes is prevented, entirely or partly, by removing carbon dissolved in the melt, this carbon being segregated by simultaneous addition of nitrogen and titanium or of nitrogen and zirconium whereby a carbonitride of the added metal is formed which solidifies at a higher temperature than does the remaining melt.  The melt should then be allowed to stand motionless for a time to allow carbonitrides to rise to the surface and be removed.  Titanium may be added as a ferro alloy containing about 30 per cent of titanium and nitrogen as a high-nitrogen ferro chromium.
