Welding by pressure; shearing.-In a method of making chain links 11, Fig. 8, in which the ends are resistance welded, the flash 16 is removed at least in part by shearing knives before any further operation on the weld. In one example, a pair of shear blades 36 arranged to remove diametrically opposite portions of the ridge 16 are mounted on the supports 35 for one of the upsetting jaws 15 of a resistance welding machine. A slide 34 carrying the blades 36 is actuated by a cam 29 on the machine drive through a slotted lever 31 and an adjustable screw 33. Swaging jaws (not shown) then operate upon the remaining portion of the weld ridge and the remaining flash is removed by other knives (not shown). In another example, the weld ridge 16 is entirely removed by a pair of knives 38, Fig. 11, with half round cutting edges enclosing the periphery of the link section and moved longitudinally to sever the ridge. The knives are slidably mounted on levers 37, Fig. 12, of a swaging machine from which the swaging jaws have been removed and are actuated by cams to perform the shearing operation. Specification 688,962 is referred to.

Title: Improvements in axial flow turbomachinery vanes
IPC: F01D5/18
Filed: 1969-07-01
Abstract: 1,261,765. Turbine and compressor blades. GENERAL ELECTRIC CO. July 1, 1969, No.33196/69. Heading F1T. A hollow rotor or stator blade for a gas turbine or compressor has a heating or cooling arrangement comprising hollow inserts 50, 51 defining central and leading edge chambers 60, 65 and spaces 62. In the case of a cooled stator blade, compressed cooling air is supplied to the radially outer end of the chamber 60 through an inlet 53 in a cover plate 52. Chamber 60 is closed at its inner end so the cooling air leaves through radially spaced holes 56 to impinge on the interior surfaces of the blade walls 41, 42 adjacent the trailing edge 46. Some of the air discharges to the exterior of the trailing edge through holes 70. The insert is spaced from the blade walls 41, 42 by radially spaced ribs 57 to define chordwise extending passages. Some of the air is deflected from the trailing edge region and through these passages towards the leading edge insert 51. The latter has holes 64 through which the air enters chamber 65 to impinge upon the leading edge 45 before flowing radially inwards to discharge from the blade through an opening 47. The flow crosssection of chamber 65 may increase in the radially inward direction. The discharged air cools the inner shroud ring 31 and reduces leakage past seal elements 39, 40. Additional air may be supplied to the seal by enlarging opening 47 so that some air discharges directly from space 62. In a modification the entire cooling air-flow first impinges on the interior blade surfaces in the region of the leading edge 45 rather than the trailing edge 46, a portion of the air then flowing to the trailing edge. The passages and chambers within the blade may be formed by machining or during casting, rather than by inserts 50, 51. The construction may also be used for de-icing compressor blades using a heating fluid.
