Title: Improvements in or relating to methods of and devices for purifying high melting-point metals
IPC: C22B9/10
Filed: 1965-11-17
Abstract: High melting point metals of Groups IVa, Va and VIa of the periodic system of elements are melted and have added a purification agent which will form a volatile sub-oxide with the impurity to be eliminated.  Thus for an oxygen impurity, C, Si, Al, a metal carbide aluminide or silicide may be added and if the impurity is carbon or silicon an oxide of the metal being purified is added.  The purification is preferably carried out at reduced pressure (e.g. 10-5 to 10-6 mm. of mercury).  The purification agent may be added before or after melting of the metal which may alternatively be melted in a crucible of the purification agent.  In examples the treatment is carried out in an electron-beam furnace.

Abstract: 1307687 Windows BOUSSOIS SOUCHON NEUVESEL 30 Oct 1970 [19 Nov 1969] 51745/ 70 Heading E1J In an alternative movement window, a leaf, e.g. sashless, is displaceable horizontally in its plane between a closed position V, a position O in which pivoting about horizontal bottom axis X is possible, and a position B in which pivoting about vertical side axis Y is possible. The displacement is effected by a handle 5 on the leaf operating a bolt 6 which is releasably connected to the main frame 2. In an upper edge fitting 12 (Fig. 5) pivotable arms (125, 133) carry studs (71, 134) engagable in recesses (124, 136) and studs (72, 72) slidable in guides (123, 135). In lower corner fitting 15 (Fig. 12) rollers (53) are mounted in sleeve (23) on the leaf and run on rod (22) having a ring (31) pivoted on the frame. In closed position V pins (112a, Fig. 6) of hinges 16 are engaged in their sockets and pin (134, Fig. 12) is engaged in recess (136). On movement the leaf to position O rollers (53, Fig. 12) engage notches (330) to locate the leaf and pins (7', 134) are released from recesses (124, 136) but the studs (72 and 73) remain engaged in guides (123, 135) and the pin (112a) of hinge 16 has not left the socket (110). When the handle 5 is pulled towards the interior of the room, the leaf pivots about the lower axis X on the hinge pins (112a) in the sockets (110) and on the supporting rod (22) until stopped by arms (125, 133). Stop (37) then engages in a slot in the hinge ring (31) to prevent displacement of the leaf 4 along the axis XX. If the handle 5 is rotated to position F b  the leaf is moved to position B in the frame, accurate positioning being ensured by rollers 53 falling into notches (33b, Fig. 12) and further movement towards the left by the handle is prohibited by flange (62) contacting stop (34) on the rod (22). In position B stud (73) is freed from guide (135) and pin (112a) has moved clear of its socket (110) so that the leaf 4 can be rotated about axis Y, Y on pin (26) of rod (22) in ring (31) and stud (71) in recess (124). Return of leaf 4 to position "O" is prevented by flange (59) of sleeve (23) striking shoulder (45) of lug (41) which is moved by spring (39). The rollers (53) may be replaced by spring pressed balls or notches may be provided on the underside of rod (22) to be engaged by spring pressed push rods on a block secured to the bottom edge of the leaf.

Abstract: 1,018,828. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 29, 1964 [Jan. 21, 1964], No. 52657/64. Heading G6C. A nuclear fuel element 2 consists of a tube 4 of fissile material enclosed within a can 8 of a material of low neutron absorption on the outer surface of which are longitudinal series of cooling fins inclined to the axis of the fuel element (the outline of which is shown in chaindotted lines) and longitudinal centring splitters 20 integral with the can 8 which centre the fuel element in a sleeve 19 of neutron-moderating material, each of the splitters 20 terminating at a distance short of the ends of the can which is at least equal to the radial distance to which the splitters extend from the can. This construction makes it possible to eliminate weld fractures between the can 8 and its end caps 14 in the lines of extension of the splitters 20. Instead of terminating in a straight radial edge, the splitters 20 may terminate in an edge having an inner portion which forms a junction curve with the can 8 and an outer portion which is inclined to the axis of the fuel element so as to reduce strain-hardening at the bases of the splitters 20. In order to eliminate torsional stresses, the splitters 20 may be divided into separately deformable sections by means of radial cuts 24 which extend at least to the level of the fin tips. The splitters 20 preferably have a tapering transverse cross-section, the maximum thickness being adjacent the can 8 and the tips being fitted within grooves formed for this purpose in the sleeve 19. The fuel element is restrained axially with respect to the sleeve 19 by means for any suitable device, for example of the type described in Specification 907,625. Where the cooling fins are all inclined in the same direction, the number of splitters 20 is equal to the number of longitudinal series of fins, but where the cooling fins are arranged to form a " herringbone" pattern, the number of splitters 20 need only be one half the number of series of fins since the splitters do not serve in any way as deflectors. The tube 4 of fissile material is formed, for example, of either pure or low-alloy uranium and is closed at each end by means of a uranium pellet 6. The can 8, which may be of a magnesium-zirconium alloy of low zirconium content, is closed at each end by a welded cap 14 of a magnesium-manganese alloy of low manganese content. Discs 15 of heat-insulating material are located between the pellets 6 and the caps 14. The internal face of the can 8 is provided with circular ribs 10 which fit inside corresponding channels 12 of the tube 4 in order to prevent ratcheting.
