Title: Improved method of consolidating metal powder to dense coherent form
IPC: B22F3/04
Filed: 1945-01-05
Abstract: 601,057. Powder metallurgy. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Jan. 5, 1945, No. 562. Convention date, May 13, 1943. [Class 83 (iv)] A method of forming dense coherent bodies from metal powder selected from molybdenum, tungsten, nickel, iron or copper, comprises compressing the powder in a mould and then treating in a gaseous hydrogen-bearing reducing atmosphere to a temperature not higher than 70 per cent of the fusion temperature of the powder, the gaseous atmosphere containing sufficient water vapour to produce a reversible reaction between the powder and the gaseous atmosphere at the heating temperature employed. In the case of iron and copper the gaseous atmosphere may comprise a mixture of hydrogen and ammonia. According to one example, a pressed molybdenum ingot was heated for two hours at 1630‹ C. in hydrogen saturated with water vapour at 40‹ C. The heating could however be carried out at a temperature as low as 1550‹ C., the saturation temperature being 30‹ C., or even ordinary room temperature. For tungsten, temperatures of from 1600‹ C. to 2000‹ C. are desirable. The initial compression of the powder is preferably carried out hydraulically in a flexible rubber container. As shown, in Fig. 1, the powder mass is in the shape of a tube around a slightly tapered mandrel 16 and enclosed by a rubber hose 10 closed at the bottom by a boss 12 and at the top by a cap 15. A number of moulds may be arranged within a container 14 into which water may be pumped through the inlet 23 to a pressure of up to fifty tons per square inch.

Title: Guiding a working head
IPC: B23K9/025
Filed: 1974-01-07
Abstract: 1459103 Welding by fusion MITSUBISHI JUKOGYO KK 7 Jan 1974 [8 Jan 1973 2 Feb 1973] 00595/74 Heading B3R In moving a working head (e.g. for inspecting, surface finishing, cleaning or, as shown, welding) along fillet lines a, b and b, c between intersecting walls and a base of a structure, such as the lattice structure shown in Fig. 1A, in order that the head may operate into and out of the corner b between said lines it is both rotated about a fixed point adjacent said corner and moved radially of said point. In Figs. 4, 5, a truck 1, supported on a structure base 5 by a driving wheel 2 and a freely rotatable castor 3, has a sucker 7 which when actuated to stick to said base provides a pivot 0 about which the truck can rotate. A structure-wall-following plate 9 having wallengaging rollers 10 is supported on the truck for free rotation about the pivot 0 and is lockable to said truck by means not shown. A welding torch 12 is horizontally slidable in said truck in a cylinder the axis of which intersects the pivot 0. The torch is fast with a cam follower 13 engaging a cam groove 14 in the plate 9. A compression spring 15 is provided between the follower 13 and the end of the cylinder 11. In operation, with the plate 9 locked to the truck with the torch normal to the structure wall, and two rollers 10 of said plate engaging said wall, the truck is driven along said wall and fillet welding is effected. When a corner is reached the leading pair of rollers 10 engages the next wall, the sucker 7 is actuated and the plate 9 unlocked, whereupon the truck and torch rotate about the pivot 0 by 90 degrees. During this rotation the cam follower 13 moves in the cam groove 14 to effect radially outward and then inward corner welding movement of the torch. On completion of said 90 degrees rotation, the sucker 7 is de-actuated and the plate 9 locked to the truck, and the truck is driven along said next wall. The position of the intersection of the axis of the tip of the welding torch and the structure may be changed by changing the mounting position of the follower 13 on the torch. In Figs. 8-10 (not shown) the cam follower 13 is inwardly spring-pressed against the peripheral edge of a cam plate geared so as to be rotationally fixed with the structure-wall-following plate 9. For structures other than rectangular plan, e.g. parallelogram plan, the wall engaging rollers are arranged on the plate 9 accordingly. In a further method (Figs. 2, 3, not shown), the tip of the welding torch is angled, in the horizontal plane, at 5 degrees to its line of radial movement. The torch tip is downwardly angled at 45 degrees and is of the CO 2  solid wire type. The torch may be followed by a second torch angularly disposed thereto about the same pivot point.

Abstract: 1,128,233. Evaporators of the vapour-compression type; distillation of water. AQUACHEM Inc. 7 Jan., 1966 [1 March, 1965], No. 951/66. Heading BIB. Liquid to be distilled, e.g. sea water, is preheated by passing it as cooling medium through the condensers of a multi-stage flash evaporator 25, the preheated liquid is submitted to distillation in a still 11 of the vapourcompression type, and the residual liquid is passed through line 30 to the first flash chamber of evaporator 25. Distillate is withdrawn from the heating-coil 21 of still 11 through line 35, and this distillate is cooled by passing it through heat-exchanger 36. Distillate is also withdrawn from evaporator 25 through line 31. Most of the distillate is produced by still 11, evaporator 25 acting primarily as a preheater for the incoming sea water. Brine is discharged from evaporator 25 through line 33: Some of the sea water to be distilled is supplied through line 26, and flows through the condensers in the right-hand half of evaporator 25. Sea water is also introduced into the system through line 37 and flows through a coil in heat-exchanger 36. The two streams of sea water are then united, acid is added through line 28, and the water enters vacuum-deaerator 29. Some of the deaerated water is pumped through the condensers of the left-hand half of evaporator 25, and the remainder flows 'through a coil in heatexchanger 36; the two streams are then united, and the preheated, deaerated water is introduced into still 11. Provision may be made for recirculating brine through the system. The compressor 20 may be of the conventional type. Alternatively, there may be used a pressure exchanger comprising a rotary valving element 67<SP>1</SP> (Fig. 4) supplied with high-pressure gas, e.g. steam, through line 80. This element, which is driven by a motor, has chambers which selectively communicate with four ports, which sequentially open and close as the element rotates. The vapour from still 50 is compressed by the creation of a shook wave 'by the high-ressure gas.
