Abstract: 1,155,488. Welding by fusion. AIR REDUCTION CO. Inc. 29 Aug., 1967 [6 Sept., 1966], No. 39449/67. Heading B3R. Gas shielded metal arc spot welding apparatus has a device for clamping the workpieces together adjacent the weld zone. A cylinder 29, mounted on a handle 35 or a fixed support, carries a C-shaped frame 20 formed in two parts 21, 22 adjustably interconnected. A consumable electrode 55 is fed by a remote device through the rod 48 of the piston 37 of the cylinder 29 to a contact tube 91 forming part of a welding head threaded into a block 60 which is a press taper fit in the end of the piston-rod 48. Gas, e.g. (argon or helium with, if desired, oxygen, or carbon dioxide) is fed through an inlet 62 in the block 60 to a two-part gas nozzle 80 having gas exit slots 82 and formed of chromium-plated brass. The nozzle 80 may be water cooled and is threaded to an insulating sleeve 76 secured by a screw 78 on the body 71 of the welding head. Current leads 67, 70 connect the welding supply via the block 60 to the contact tube 91 and via the frame 20 to a backing member 24 connected by a spherical coupling to the frame. During welding the piston 37 clamps the workpieces between the gas nozzle 80 and the backing member 24. In a modification, the electrode feeding device is mounted on the cylinder 29. The backing member, Fig. 6b, may be formed with a recess of circular or square section which is filled with weld metal to provide a reinforcing projection. A control device provided with four timers acting sequentially in response to actuation of a switch 36 causes air to be supplied to the cylinder to clamp the workpieces, and shielding gas and the electrode to be fed. The arc strikes when the electrode contacts the work and is terminated by burning back when the electrode feed is stopped. The gas flow and clamping pressure is maintained until the weld solidifies. The control device may be set to produce automatically a second weld at the same spot.

Class 40(3) [Also in Group IX] A weaving pattern 1 is associated with. horizontal and vertical rows of marks 2 and 3 corresponding to the warp and weft divisions with the aid of which it is scanned photoelectrically to control the production of punched cards or tapes. A main photo-electric cell scans along successive parallel lines A-A<SP>1</SP>, B-B<SP>1</SP>, C-C<SP>1</SP>, &c. under the control of marks 3 and applies its output through a gate which is opened by impulses produced by an auxiliary photo-electric cell scanning over marks 2 in step with the main photo-electric cell. The main photo-electric cell is thereby rendered effective to examine the pattern only at small areas corresponding to the warp and weft intersections. The main photoelectric cell has an optical system including a stop to restrict its view to a small spot-like area. The auxiliary photo-electric cell has a similar optical system including a slit stop to restrict its view to an area corresponding to the general shape of marks 2. The movements of the photo-electric cells may be effected by an assembly comprising a first carriage movable in horizontal guides and supporting in turn vertical guides for a second carriage. The first carriage supports the auxiliary cell whilst the second carriage supports the main cell. Marks 2 and 3 are preferably provided on the actual weaving pattern but may alternatively be provided on separate bands or rules.

A yarn-crimping machine comprising falsetwist or compressive e.g. stuffer-box, crimping elements, Figs. 1a and 1b (not shown) preceded and followed (in the direction of yarn travel) by heating and winding means, is operated with delivery bobbins arranged laterally alongside the machine and, optionally, with a thread extraction and/or vapour extraction apparatus. The heating means e.g. curved plates with two or more yarn tracks in the surface thereof, are vertically disposed high overhead for yarn travel downwardly and the yarn is fed and applied thereto by a displaceable and/or pivotable guide device, the height of which is adjustable by means of a guided external handle.
