Abstract: 836,001. Making turbine and like blades; extruding. WIGGIN & CO. Ltd., H. Oct. 5, 1956 [Oct. 11, 1955], No. 28963/55. Classes 83 (2) and 83 (4). A turbine or compressor blade is made by partially extruding through a die a metal billet 1 having one or more transverse holes 2 filled with a material which will flow with the billet metal and may subsequently be removed, whereby during the extrusion the holes are converted into U-shape 6, Fig. 7, with the end of each arm of the U lying in a side face of the root and the arm then curving inwards to run longitudinally of the blade. Four circular holes are first drilled in a rectangular billet, the holes are then filled and the billet is extruded parallel to the holes to elongate it and reduce its thickness; the holes are thus converted into elliptical shape, Fig. 1 (not shown). A billet length 1, Fig. 2, is then cut from the extruded billet and is itself extruded in a direction perpendicular to the filled holes 2 through a die of aerofoil shape. The. extrusion is stopped whilst enough unextruded billet metal remains in the container to form the root. The root may be subsequently converted into fir-tree shape, Fig. 9 (not shown), by forging and machining steps. A shroud 8, Fig. 7, may be formed at the tip end by upsetting. The holes may be exposed at the shroud end by machining, Fig. 8 (not shown). The filler is finally removed by acid leaching. Specification 763,141 is referred to.

Void [Published under Sect. 91 of the Acts]. [Classes 44 and 65 (ii).] A door, particularly for aircraft, is provided with hinges at both sides, each set of hinges being disconnectible axially so as to act either as hinges or fastenings ; both sets of hinges may be disconnected at the same time to allow complete detachment of the door in emergency- In the construction shown, the hinge pins on each side are connected by a rod 3, by which they may be lifted out of the sockets 2 on the door frame ; the rods 3 are actuated by cranks from transverse rods 9 which are spring-pressed towards the centre of the door. Each rod 9 has a slot at its inner end, in which moves a pin carrying a roller 12, the pin having its bearing in one arm 17 of a bell crank pivoted on the door. The other arm 18 of the crank has a hook which engages a projection on the rod 9 to prevent accidental disengagement of the hinges ; the arm 18 is pressed downwards by a leaf spring. The rods 9 are actuated by two pivoted arms 22, each engaging one of the rollers 12, so that when one of these levers is operated the corresponding roller is pushed, moving the crank to bring the hook clear of the rod 9 and then pushing the rod to release one set of hinges ; the parts are returned to their original positions by the springs when released. By operating both the levers 22 both sets of hinges may be disconnected, leaving the door free to be pushed bodily outwards in emergency. The levers 22 may be operated by a single mechanism, moving in one direction to move one lever and in the opposite direction for the other, or separate mechanisms may be used for the two levers. The levers may be replaced by cams or other devices.
