Title: Manufacture of nickel iron alloys
IPC: B22F9/22
Filed: 1933-05-22
Abstract: In the preparation of nickel-iron alloys an intimate mixture of iron and nickel oxalates are produced by precipitating them from a solution containing soluble ferrous and nickel salts by the addition of a soluble oxalate such as ammonium oxalates, filtering off the precipitate washing it with water until free from contaminating salts and then drying.  The precipitation is carried out at boiling point to obtain the precipitate in a readily filterable condition.  The oxalate of copper or cobalt when the latter elements are to be incorporated in the alloy are produced by co-precipitation with the iron and nickel oxalate.ALSO:Nickel-iron alloys in powder form are produced by subjecting a mixture of the oxalates of the metals to heat in a reducing atmosphere until reduction is complete and then increasing the temperature used until it is sufficient finally to homogenize the alloys.  The mixture may be heated first in an inert atmosphere such as nitrogen until the decomposition of the oxalates is complete before heating in the reducing atmosphere, such as hydrogen.  Additional metals, such as cobalt, copper, or molybdenum, may be incorporated in the alloys by adding to the mixture an oxalate of the said metals or when such metals do not yield an oxalate, an oxide reducible by hydrogen.  The intimate mixture of the iron and nickel oxalates is obtained by precipitating them from a solution containing soluble ferrous and nickel salts by the addition of a soluble oxalate such as ammonium oxalate, filtering off the precipitate washing it with water until free from contaminating salts and then drying.  The precipitation is carried out at boiling point to obtain the precipitate in a readily filterable condition.  The preparation of alloys containing 43,5 per cent of nickel, 43,5 of iron, 8,6 of copper and 4,4 of molybdenum, and 45 of iron, 45 of nickel and 10 of copper is referred to.

Title: Improvements in dovetailed metal sheets
IPC: E04C2/32
Filed: 1928-05-24
Abstract: 312,798. Heymann, M. May 24, 1928. @ronwork, constructional. - Dovetail - grooved corrugated sheets wherein tapered grooves are provided in the direction of the length of the sheets so that sheets may be interlocked at the ends to form a continuous area, are made by considering the proportioning and tapering of the grooves and the thickness of the metal used so that the sheets may interlock endwise to a predetermined extent without excessive overlap. The overlapping joint is shown in Fig. VI. The key c<1> is depressed an amount equal to the thickness of the metal used, so that the engagement between the tapered walls is made tighter owing to the taper of the walls, the centre of the key wall being depressed from level P to level Q. The displacement of the vertical through P to the vertical through Q is calculated for'any angle of taper of the corrugations, and this distance is used to replace the gauge of metal in the calculations for ordinary tapering rectangular corrugations.
