Drawings to Specification. [Class 44] The sliders of fastenings of the type in which series of interlocking members are operated by a slider are formed by cutting out surplus material from a solid blank of non-metallic material. The blank may be cut from a celluloid strip, may be moulded singly or with a number in a row, or may be cut off from a rod having a cross-section corresponding to the front view of the slider. The first operation consists in slotting the blank by a sawing operation to provide the top and bottom wings, care being taken to leave the usual neck piece connecting the wings. The inside faces of the wings are then hollowed out by two toothed wheels having cutting edges on their radial faces which edges move through the slider in the manner of the interlocking members of a finished fastener. The bridge piece for the usual pull tab, or a fixed finger knob, may either be cut in the solid blank or may be attached to the slider by cementing. Wearresisting inserts may be cemented in the slider. To remove tool marks the slider is dipped in a solvent such as acetone. Specification 391,146 is referred to.

Abstract: 827,960. Making turbine blades; extruding; forging; destructible cores. WIGGIN & CO. Ltd., H. Oct. 15, 1956 [Oct. 20, 1955], No. 30029/55. Classes 83 (2) and 83 (4). A turbine or compressor blade having passages for a cooling fluid is made from a metal blank 4, Fig. 4, having holes 2 extending longitudinally and filled with a filler material which may subsequently be removed, and whose crosssectional area is substantially equal to that of the required blade root, wherein the blank is machined over the length of the blade portion proper 5, Fig. 5, to substantially the required cross-sectional area at each point along its length, and this machined length is then changed in shape but not in length by forging. A cylindrical billet 1, Fig. 1, of a creep-resisting alloy having a nickel-chromium or a nickel-chromiumcobalt base, has four blind holes 2 drilled axially therein on an arc 3. These holes are then filled with an iron-manganese-titanium alloy. The billet is then heated and extruded through a die to form the shape 4, Fig. 4; the holes 2 are thus deformed to elliptical shape. The extruded bar is then cut into blade lengths, Fig. 5, and the central portion 5 is machined to give the final blade cross-sectional area at each point. The root portion 6 and a shroud 7 are also machined. The machine blank is then hot forged between closed dies to convert the machined shank to the desired blade contour, Fig. 7, having longitudinal taper and the root and shroud are formed to rectangular shape. The holes in the blade portion thus lie on an arc, Fig. 6 (not shown) whilst in the root and shroud they lie in a straight line, Fig. 7. The shroud may be omitted. The forged blade is then heat treated and the filler removed by acid-leaching. The root may then be machined to fir-tree shape, Fig. 11 (not shown).
