Abstract: 1413762 Dispersion strengthened alloys INTERNATIONAL NICKEL Ltd 24 Jan 1973 [31 Jan 1972] 3554/73 Headings C7A and C7D Mechanically alloyed dispersion strengthened powders of "saturation hardness" formed by dry milling according to Specification 1265343 are hot worked under correlated conditions of temperature, reduction ratio and strain rate to leave residual strain and then zone annealed to form coarse grains elongated in the working direction. Hot working is preferably effected by sheathing the powder in a steel can and extruding at 870- 1200C, a reduction ratio of 7-35, and a strain rate above a defined minimum value. The preferred temperature and reduction ratio conditions fall within the area KLMNOK of the Fig. Zone annealing is effected at 1200C minimum and the rate of travel of the hot zone may be 25-432 mm./hour. The preferred alloy contains in wt per cent 5-60Cr, 0.5-6.5Al, 0.5-6.5Ti, 0-15Mo, 0-20W, 0-10Nb, 0-10Ta, 0-3V, 0-2Mn, 0-2Si, 0-0.75C, 0-0.1B, 0-1Zr, 0-0.2Mg, 0-6Hf, 0-35Fe up to 10% volume of a refractory dispersoid e.g. TLO 2 , Y 2 O 3 , La 2 O 3  and rare earth oxides, and balance of at least 40 of Ni and/ or Co. The hot worked billet is maintained for a minimum of 5 minutes and preferably above 10 minutes at the grain growth temperature. After annealing the billet is solution treated at 950- 1320C for ¢-16 hours and then aged at 620- 870C for 1-100 hours.

Abstract: 1376076 Printed circuits; resistors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 27 Jan 1972 [3 Feb 1971 9 Feb 1971] 3840/72 Headings H1R and HIS A method of making a printed circuit comprises applying a conductive paste having noble metal particles in flake form and metal particles in dendritic form dispersed in a thermosetting binder to an insulating surface on a base in a desired pattern, curing said binder, applying a resistor paste between desired parts of said conductive film, covering the resultant resistor film with insulating means and providing a metal coating on exposed portions of said conductive film by electroless plating. In one embodiment particles of silver powder in flake form are produced by working electrolytic silver powder mixed with stearic acid in a stamping mill, adding further stearic acid and working in a ball mill, and washing in methyl alcohol before drying. Copper powder in dentritic form, produced by an electrolytic deposition method is then mixed with the silver powder and this mixture is dispersed in a vehicle containing phenol, xylene, urea or epoxy resin and Carbitol the resulting paste being applied to the surface of a phenol or epoxy resin or glass sheet using a 160 mesh screen stencil and cured. A resistor paste composed of finely divided acetylene black dispersed in a vehicle of benzyl alcohol and xylene modified phenol resin is likewise applied to the epoxy resin sheet through a 200 mesh screen stencil. An insulating paste consisting of silica, epoxy resin, and ferrocyan blue is then applied over the resistor film and cured before immersing the base thus produced in an electroless plating bath composed of an aqueous solution containing copper suphate, sodium carbonate, Rochelle salt, sodium hydroxide and formaline. Preferred percentage compositions by weight and/or volume of the mixtures are given. The silver may be replaced by gold or platinum and the dendric copper by iron.
