In lining a structure, e.g. a steel pressurevessel, with sheets of a metal, e.g. titanium or a titanium-base alloy, requiring a protective gaseous environment during welding, the sheets are assembled with edge portions in contact and spaced from the structure so providing a passage for protective gas, and openings are formed through the edge portions which are welded in a series of steps in which the protective gas is fed through an opening into the passageway until the weld reaches adjacent the opening, the opening is plugged with weld filler material and gas is fed through the next opening towards which the weld is continued. The edge portions are joggled and overlapped to form the passageway 4, Fig. 1, between the structure 3 and the lining sheets 1. The apertures 2 are formed in the overlapped portions. In a modification the edge portions of the lining sheets 10 are flanged to form the passageway 13 and the apertures are formed by opposed corrugations 12 in the flanged edge portions.

Regulating; valves.-In a two-stroke-cycle engine having two or more cylinders with pistons of two diameters, each pair of cylinders is controlled by a reciprocating hollow cylindrical valve 3, Fig. 3, divided into two compartments. The lower part controls the admission of the charge through ports 5, 6 into the spaces above the pump pistons 2, and the upper part controls the transfer of the compressed charge through diametrically opposite ports 8, 10 to the combustion chambers of the cylinders. The engine is cross-connected so that each pump delivers to the opposite cylinder. Fig. 7 shows a modification in which the valve is in two parts 21, 22 connected by a flexible or jointed rod 23 which may be adjustable for regulating the valve openings. The parts 21, 22 have open ends facing each other, the outer ends being closed. The port 32 communicating with the carburettor is connected by two closed passages 33, 34 to ports leading to the pumps 2. The compressed charge passes to the interior of the valve on one side through ports 36, 37, and on the other side through port 35 which is cleared by the upper edge of the port 22 in its lowest position.

Gear-cutting; attachments for planing, shaping, and slotting.-An attachment for planing, shaping, and slotting machines to enable bevel - wheels to be generated, is provided with means for rolling the gear relatively to the fixed path of reciprocation of the cutting-tool. A cutting-tool of truncated V form is employed and cuts on one edge only at a time, being set by means of a profile gauge adjustably carried by the attachment so that the apex corner of the cutting-edge moves along the line B, C. The blank is carried by an arbor 32 secured in a sleeve 34 rotatable in a carrier 31 angularly adjustable on guides 30 to bring the pitch-cone tangent to the plane containing B, C and normal to O, A. The carrier is clamped on the guides 30 as shown in Fig. 6. The blank arbor is adjustable axially at 46 to bring the edge D of the blank to the calculated distance from the pitch-point O, a, reference gauge-pin being provided for this purpose. The guides 30 are carried by a sector 17 rotatable about the axis O, A on a pin 16 carried by the base 13 of the attachments. After the blank has been set as above described, the whole attachment is tilted, about a bed 25 resting on the machine table, by means of a screw 26 to bring the bottom 60 of the space being cut parallel to the line of motion of the tool. The carrier is swung about the axis O, A by worm gearing 18, and the blank is rotated about its own axis by worm gearing 35. To secure a true rolling motion, the worm shafts 19, 37 are connected by a train of change-gears containing a dividing-head for spacing the teeth. In a modification, the sleeves for the cutter arbor are provided on the carrier 31 interconnected by gearing, in order that gears may be cut having a large range of cone angles without unduly prolonging the guides 30.
