Title: Process for producing cold-rolled steel sheets to be deep drawn
IPC: C21D1/28
Filed: 1962-11-21
Abstract: 1,027,158. Producing metal sheet; altering physical properties. YAWATA IRON & STEEL CO. Ltd. Nov. 21, 1962 [Dec. 2, 1961], No. 44032/62. Headings B3A and B3V. A process for producing steel sheets to be deep drawn includes hot rolling an ingot, normalizing the resulting coil at or just above the A 3  point, after an optional cold rolling step, cold rolling the normalized steel with a 40- 80% reduction, and then annealing it. In an example a sheet of percentage composition 0À09 C, 0À007 Si, 0À39 Mn, 0À018 P, 0À017 S, 0À08 Cu and balance Fe, was hot rolled, normalized from 950 C., cold rolled 30-80% and annealed at 650 C. for 2 hours in an atmosphere containing 5% CO 2 , 10À5% CO, 0À5% CH 4 , 12À5% H 2 , 0À8% H 2 O and balance N<SP>2</SP> with a dew point of 5 C. Normalizing may take place in an inert gas, molten salt, molten metal or an oxydizing gas. The grain size and physical properties of the resulting steel make it suitable for deep drawing.

Abstract: 1417212 Colour television tubes TEXAS INSTRUMENTS Inc 20 Sept 1973 [13 Dec 1972] 44197/73 Heading H1D Local distortion of the shadow mask in a colour television tube is reduced by forming the mask of a metal laminate material, one layer of which is of mild steel to provide mechanical strength, and another layer of which is of a material of greater thermal conductivity than the steel. As described, the high thermal conductivity material may be copper, with a layer of steel on one or both sides, which may be darkened to increase cooling by radiation. One or both sides of the composite structure may be coated with a thin layer of nickel, to facilitate the etching of the mask apertures during manufacture.

Apparatus for cutting holes in thin flexible webs comprises a bearing structure 17, 18, Fig. 4, a tubular rotatable cutting-tool 27 journalled at 25, 26 in said bearing structure and terminating in an outwardly-directed circular cutting edge 29, a resilient peg 59 having a non-skid surface lying substantially at right angles to the axis of the cutting-tool and normally spaced therefrom to receive a web 61 between it and the cutter, power means adapted to rotate the cutting tool about its axis and means for bringing the peg and cutting edge relatively together to cut a hole in the web. A number of cutters 27 are mounted in line in the structure 17, 18 and the pegs are similarly disposed in line above them in a vertically movable elongated member 55. Each cutter 27 has an interchangeable cutting head 28 having an edge 29, below the tubular portion 30 of which is a notch 31 to radially eject cut discs, and an axial shank terminating in a bifurcated end having abutment portions 34 so that they may be inserted into the hollow open-ended shaft 35 to which a gear 39 is rigidly secured. The gear 39 intermeshes with corresponding gears attached to the neighbouring tools, one tool being driven directly by a motor which includes a sprocket and chain driving a further tool to distribute the driving force among the cutters. In operation, the web is advanced intermittently and when it is at rest a cam and roller 73, 74, Fig. 3, actuates bars 67, by movement of the pivot arms 65, 69 to depress the elongated member 55 and pegs 59, against the action of compression springs, to contact the web, the cam disc 73 being mounted on a short shaft 71 having a sprocket 72 on its other end driven by a chain 75. As the pegs are depressed they also depress, against the action of springs, a stripper-bar 52, which is disposed above the line of cutters and has holes corresponding to the latter; the cutters then contact and cut the web. The pegs, which are removably mounted in the member 55 to facilitate cutting of different numbers of holes, are made of resilient material such as wood, rubber, or synthetic resin which is arranged to have the necessary non-skid surface contact with the web.

Abstract: 1,047,399. Fuel materials. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Nov. 23, 1964 [Nov. 25, 1963], No. 46564/63. Heading G6C. A nuclear fuel, suitable in particular for a high temperature gas-cooled reactor, comprises a mixture of uranium and plutonium sesquicarbides. The sesquicarbide is the stable phase in a uranium-plutonium-carbon system up to a temperature which varies from 1670‹ C. when the uranium-plutonium atomic ratio is 95: 5 to 1720‹ C. when the said ratio is 90: 10. In the absence of free carbon, the sesquicarbide would be the stable phase up to higher temperatures than those quoted, but when the fuel is in the form of small (i.e. about 250 microns diameter) " kernels," the coatings of these kernels usually possess a thin inner layer of carbon. The mixed sesquicarbides may be prepared by any of the known methods, e.g. by arc-melting the metals in the appropriate quantities with carbon, by " plunge sintering " in the manner described in Specification 914,153, or by reacting together uranium and plutonium dioxides and carbon in the requisite proportions. By way of example, 12À75 gm. of uranium metal and 2À25 gm. of plutonium metal in the form of small cubes having sides about 3 mm. long were placed, together with 1À50 gm. of graphite, also in the form of 3 mm. cubes, in the hearth of an arc furnace. The mixed charge was melted and caused to react by striking an arc between the charge and a graphite electrode in an atmosphere of argon. After 1 min. the arc was switched off and the charge allowed to cool, the resulting button of material being turned over and remelted, this being repeated six times to ensure the uranium-plutonium-carbon alloy was homogeneous. The product was found to be a mixed uranium-plutonium dicarbide. The mixed dicarbide was then transferred to a vacuum furnace and heated to about 1700‹ C. for a period of 6 hours at a pressure of 10<-5> mm. of mercury. Subsequent metallographic examination of the material from the vacuum furnace showed it to be a dispersion of graphite in a continuous matrix consisting of a solid solution of uranium and plutonium sesquicarbides.
