Title: Improvements relating to the distillation of metals
IPC: C22B5/16
Filed: 1948-09-06
Abstract: A process for distilling a normally non-volatile metal from a metal-bearing material comprises contacting the material with the vapour phase of the halide of a volatile substance at a temperature and pressure at which occurs an endothermic reaction resulting in the formation of the vapour of the stable halide of the normally non-volatile metal and the vapour of the volatile substance, and converting the resultant vapour mixture into the normally non-volatile metal and the halide of the volatile substance by the reaction of the vapour of the volatile substance with the vapour of the halide of the normally non-volatile metal, whereby the normally non-volatile metal condenses.  The volatile substance may be a metal or a non-metal, or a volatile, stable or unstable, lower halide.  In the latter case the normally non-volatile metal to be distilled is contacted by a higher halide of a metal or non-metal, which higher halide need not be volatile, resulting in the formation of the vapour of the normal halide of the normally non-volatile metal and the vapour of the lower halide of the metal or non-metal.  The conversion of the resultant vapour mixture may be brought about by cooling or absorption of the normally non-volatile metal whereby the metal condenses as absorbate.  In the former case, the vapour which is brought into contact with the metal bearing material is preferably in the unsaturated state so that the halide of the volatile substance and the normally non-volatile metal condense separately.  The method may be used for separating, e.g. baryllium and vanadium from impurities, such as oxides or carbides, or for obtaining non-volatile metals from alloys, or intermetallic compounds, e.g. ferro-manganese, ferro-vanadium, ferro-chromium, ferro-titanium, ferro-molybdenum, and ferro-tungsten.  Specification 620,071 is referred to.

Abstract: 1504526 Injection moulding composite containers AIRFIX INDUSTRIES Ltd 28 May 1975 [28 May 1974] 23664/74 Heading B5A A composite container is made by positioning blank sheet material 2 (3) in a blank cavity defined by mould tools 6, 7 with edges to be seamed juxtaposed. The tools define a seam mould cavity 9 in the region of said juxtaposed edges, a bead mould channel 16 and a feed channel communicating with the seam cavity. The blank sheet material extends (in its initial position, as shown at 16a) between the feed channel and the bead mould channel. Material is injected into the seam cavity and thence to the feed channel, where it forces blank sheet material into conformity with the bead mould channel, the depth of the bead mould channel being reduced in the zone (Fig. 3) where it overlies the seam cavity to support the juxtaposed edges in that zone against displacement at least during the initial stages of injection and so prevent material flowing from the seam cavity directly into the bead mould channel. The reduction in depth may be permanent or, as shown in Fig. 3, may be effected by a plunger 20 which is retracted when a suitable flow of material has been established in the feed channel.

Filed: 1928-08-17
Abstract: 296,088. Gache, C. P., and Paris, H. V. Aug. 25, 1927, [Convention date]. Screwing; chucks.-A screwing-machine particularly for screwing the ends of gudgeon pins has a hollow spindle chuck automatically operated by a push spindle and containing an ejector. The chuck closing mechanism and the ejector are controlled by cams on a shaft driven through a clutch controlled by lever mechanism from the lever fed tailstock carrying the die-bead. The tailstock 5 is adjustable, on the bed 1 according to the length of the work, the collar 30 for the lever feed being also adjustable for this purpose. The collar 20 is adjustable to determine the length threaded. A cam 22 on the die-head 21 actuates through linkage 27 a rock shaft 32 having a lever 34 keyed to it and provided with a finger 38 for actuating a second lever 35. An abutment 39 supports the lever 34 against lateral thrust when in operation. The levers control a clutch for transmitting drive to a cam shaft controlling the chuck lever 63 and ejector lever 65. On actuation by the cam 22 both levers 34, 35 are actuated and their pins are withdrawn from an inclined groove 47 and an axial groove 48, Fig. 4, respectively. Springs 50 now force the clutch 45, 46 into engagement and the gearing 49 becomes operative to drive a cam 53 at half the speed of the shaft 40. By the time the cam 22 has released the levers the member 46 has rotated sufficiently to prevent the pins from reengaging with the grooves in it. Towards the ends of a revolution the pin on the lever 34 drops into the groove 47 and further rotation of the clutch then effects its disengagement, the pin on the lever 35 then dropping into the groove 48. The cams 54, 55 are so arranged that on one hali revolution the chuck is closed and on the next half revolution tl e chuck is opened and the ejector actuated. On the return of the tailstock spindle a roller on a bell crank lever 87, Fig. 1, engages a fixed cam to re-set the self-opening diehead.
