Patent GB-1057035-A (GB)
Title: Manufacture of aluminium compounds
Inventor: BOLGER DEREK EDWIN
IPC: C01B25/06
Filed: 1963-08-26
Abstract: AlAs, AlP, AlAs#cP1-#c, Ga#cAl1-#cAs and Ga#cAl1-#cP (where 0 \sF #c > 1) are manufactured by a method which includes the disproportionation of an unstable volatile aluminium halide in the presence of an excess of arsenic and/or phosphorus in the vapour phase.  This step may be achieved by vaporizing As and/or P and passing the resultant vapour by means of a carrier gas (e.g. H2) into a reaction zone in which a stable volatile Al halide is passed over molten Al to obtain the required unstable volatile halide (e.g. AlCl).  The reaction zone is maintained at such a temperature that the unstable volatile halide disproportionates to yield the finely divided Al which takes part in the reaction.  The stable volatile aluminium halide may additionally be passed over molten gallium to obtain the mixed arsenides and phosphides.  The compound produced may be epitaxially deposited on a substrate located in the reaction zone. The molten Al may be at 1100-1200 DEG  C. and the reaction zone 30 DEG  C. cooler.  An impervious Al2O3 tube is suitable as the reaction zone.  Two forms of apparatus are described and illustrated in the drawings, by means of which the As and/or P vapour is kept separate from that of the AlCl vapour until the reaction zone is reached.

Abstract: 1315198 Heat pipes SANDERS ASSOCIATES Inc 14 July 1970 [8 Oct 1969] 34203/70 Heading F4U In a heat pipe the capillary structure 12, Fig. 1, which may be a wick or a plurality of grooves in the pipe wall, does not occur on the condenser surface portion 18 and the pipe is so arranged that the condensate 24 returns to the capillary structure by gravity so that reversal of heat transfer may not occur. In a further embodiment, electronic apparatus 44, Fig. 3, is cooled by heat transfer to two or more adjacent heat pipe systems 30, 32 each comprising an evaporator container 34 having a wick 36 connected by flexible wick sections 38 to heat sink channels 40 disposed longitudinally in but isolated by a vapour space 58 from the surface of a double walled container 42 or aircraft skin, which channels have no wick structure. Vapour condensed in the channels flows by gravity to the flexible sections 38 for gravity and capillary flow to the evaporator container. The outer surface of each channel 40 and the outer surface of the inner wall 50 of the container 42 is covered by a wick 54 and is separated from the outer wall 56 of the container by the vapour space so that the heat from vapour condensed in the channels 40 evaporates liquid from the overlying portions of the wicks 54. This vapour condenses on the inner surface of the wall 56 and flows by gravity to the bottom of the space 58 and is returned by capillary action to the evaporation area. In a modification, the flexible sections 38 may be contiguous with the wick 54 and the evaporator chamber contiguous with the space 58 so that the vapour from the evaporator 34 will pass directly to the space 58 for condensation.

Abstract: 505,681. Pipe couplings. CHISHOLM, G. D., and AVERY, C..J., [Representatives of AVERY, W. L.], and AVERY EQUIPMENT, Ltd. Dec. 11, 1937, No. 34395. [Class 99 (i)] Each member 10, 11 of a coupling has a valve 16 or 21 that closes when the members are uncoupled and opens when the members are coupled together, coupling being effected by a linkage operated by a lever 33. In the form shown in Figs. 1 and 3, the lever 33 has two side members each carrying a bush 40 having an inwardly projecting bearing 30 and , between the side members a link member with side parts 26a, 26b mounted on the bearings. The bushes have eccentric holes by which they are mounted on pins 31 projecting from the coupling member 10. Each side of, the link has a hook 36 for engagement with a projection 37 on the coupling member 11. Owing to the eccentric mounting of the bush, when' the lever 33. is rotated the link is moved longitudinally and the coupling members are drawn together. The hooks are held in engagement with the projections by a leaf spring 39. Fig. 5 shows an alternative form of the linkage in which the lever 33 carries eccentric bearings 49, 50 on which members 42, 43 of the link device are mounted respectively. When the lever is turned the links draw together projections 31, 37 on the respective coupling members. When the link is in the.position shown, the coupling members are held tightly together and a spring-pressed catch 51 prevents the lever from moving. Instead of hooks for engaging the projections on the coupling member the links may have holes fitting the projections. The arrangement of the valves in the coupling members is shown in Fig. 3. The valve 16 is fixed inside the coupling member 10 and moves the valve 21 from its seat during coupling. At the same time a projecting part 20 on the coupling member 11 moves a piston 13 away from the valve 16 and thus allows a free passage through the coupling members. Specifications 476,801 and 480,241 are referred to.

A machine for stacking angle irons or other rolled profiles includes magnetic grippers which remove a group of profiles from a rollerway &c. and carry it beneath a further gripper set, turning alternate groups upside down to produce interengagement between adjacent layers, the further set taking over each group and depositing it on previous groups. Angle irons 2 are advanced (by a rollerway 1) against a stop (not shown) and are lifted clear by arms 4a to which are pivoted the grippers 14, the arms being mounted on carriages which are raised by their tracks 3. The tracks are supported on links 5, 6 and moved by piston and cylinder means 9. The carriages are moved along the tracks by a chain 11 to bring the group beneath vertically movable gripper heads 15. During transit, the grippers 14 may be pivoted by a common shaft 4b to turn the group over. The heads 15, which are offset relative to the grippers 14, engage the group and the carriages withdraw and descend. The group is then lowered into pockets 16 on a conveyer. When a stack has been formed, the pocket moves to position 16a where operators tie the stack to form a bundle. An arrangement in which the rollerway is lowered to place the group on the grippers 14 could be employed (not detailed).
