Patent GB-1030929-A (GB)
Title: Production of metal-carbon compounds
IPC: C01B31/30
Filed: 1963-10-24
Abstract: <PICT:1030929/C1/1> Carbides of uranium, vanadium, niobium, tantalum, chromium and tungsten are prepared by contacting the metal at an elevated temperature in a reaction zone with a circulating stream of gaseous aliphatic hydrocarbon, and the hydrocarbon stream, after leaving the reaction zone, is substantially freed of by-product hydrogen by diffusion of the hydrogen through a selective carrier, and is returned to the reaction zone.  The metal, e.g. uranium of particle size about 1/8 inch, or non-particulate when only a uranium carbide coating is to be formed, is heated in furnace 10 at 750-1100 DEG  C. when uranium carbide is the desired product, or at 1150-2100 DEG  C. in the case of uranium di carbide.  This higher temperature range is also employed for the other metal carbides. Gaseous hydrocarbon, e.g. methane, is supplied through conduit 14 and inlet 10a when of high purity, i.e. about 99.9%, otherwise the gas is first purified by passage over a platinum, palladium, rhodium or ruthenium catalyst on a conventional support in converter 15 to be referred to hereafter.  Gaseous reaction products leave the furnace 10 via 11a, are heated, if necessary, to above 250 DEG  C. in preheater 21 and pass via conduit 17 to diffusion unit 16.  As shown, this comprises a casing 18 and a tubular coil 19 of preferably palladium or a palladium-silver alloy.  Separated hydrogen accumulates in chamber 20 while substantially hydrogen-free hydrocarbon leaves via 28 and is returned to the furnace.  Other forms of diffusion unit are illustrated in Figs. 2 and 3 (not shown) or are described in Specifications 975,819 and 992,695. A major proportion of the hydrogen leaving chamber 20 via line 25 is bled via line 26 and the remainder is mixed with impure incoming hydrocarbon in 24, preheated in 50 to 100-500 DEG  C. before catalytic hydrogenation of the impurities or cracking of the higher hydrocarbons in 15 at a pressure of between 1 and 250 atmospheres.  Purified hydrocarbon passes via lines 27 and 28 to the reactor 10, or is recycled if necessary via line 55 to the reactor 15. Hydrocarbon is recycled through reactor 10 about six times until it consumes stoichio-metrically.

Abstract: 1,163,733. Washing casks, etc.; endless conveyers. JOSEPH SANKEY & SONS Ltd., and C. G. GOLDING. 4 Oct., 1966 [5 Oct., 1965], No. 42153/65. Headings B8A and B8T. A metal cask, &c. 12, Fig. 3, having two concentric inlet, &c. valves, is placed upside down on a conveyer (15), Fig. 11 (not shown), which advances it beneath a cross-plate (19) so that it actuates a control 21, Fig. 3, between the chains of the conveyer, the control halting the cask, &c. and causing an hydraulic servo 41, Fig. 5, to be energized, thus raising a washing head 14 into abutment with the valves on the cask, which is itself carried upwards against the cross-plate, so that cold water, compressed air, hot detergent, hot rinsing water and compressed air can then be passed through the cask to wash it. The washing head 14 comprises an inner supply passage 47, 59, Fig. 5, for engagement with the inner of the two valves on the cask, surrounded by an outer drain passage 66, the two being formed in a twoplate structure having rods 44, 45 slidable up and down through holes in a fixed frame 43 when the hydraulic servo 41 is energized, &c. A supply system connected to the washing head 14 has pneumatically actuated valves 85-88, Fig. 6, controlling respectively an inlet 81 for sterilized compressed air, an inlet 82 for cold water, an inlet 83 for hot water and an inlet 84 for hot detergent. The hot detergent is supplied from two heated tanks 78, 79 whose level is balanced by a connecting pipe 89, the tank 78 having an expansion tank 90. The detergent from the two tanks 78, 79 passes through a filter 100 and a pump 97 to the inlet 84. The compressed air and liquids are fed through a pipe 72 to the inner washing supply passage and thence to the cask, &c. 12; the outer passage feeds into a pipe 74 leading to a two-way valve 75. In one position, the valve 75 connects the pipe 74 to a drain 76, to which compressed air, and the cold and hot rinses, are passed. When detergent is passed through the pipe 74, the valve 75 is turned to its other position, connecting to a pipe 77 and the tank 78, so that the used detergent is recirculated. The sequence of operations triggered-off by actuation of the control 21 is effected by an automatic electric, &c. control system including clocks which time each separate washing, &c. function. When the final charge of compressed air has been passed through the cask 12, the servo 41 lowers the washing head 14 so that the cask, &c. is replaced on the conveyer 15. The control 21 is lowered by a pneumatic servo, and the conveyer 15 moves the cask 12 out of the machine; as it passes a trigger 22, a stop 23 is withdrawn from the path of the next cask, &c., which is advanced by the conveyer to the control 21, already returned to its operative position. The washing sequence is then once more performed.

Title: Improvements in or relating to the manufacture of flat glass
Inventor: ROBINSON ALBERT SYDNEY
IPC: C03B18/04
Filed: 1962-11-09
Abstract: In the manufacture of flat glass in ribbon form during which molten glass delivered at a controlled rate is advanced along a bath of molten metal in the form of a ribbon, the molten glass delivered to the bath is allowed to flow in a direction away from the direction of advance of the glass ribbon to form a heel and the molten glass in the heel is caused to be displaced so as to allow a continuous replacement of glass in the heel and so prevent the formation of a stagnant zone in the heel. Molten glass 14 (Fig. 2) is fed through a spout 3, which overhangs the back wall 8 of a tank containing a bath 6 of a molten metal, on to the bath 6.  The flow of the molten glass is controlled by a tweel 2. The glass is advanced along the bath in the form of a ribbon, a heel being formed at 13.  To cause the glass in the heel to continuously flow, preferably in a direction transverse to the direction of advancement of the ribbon 10, a greater quantity of <PICT:1068345/C1/1> <PICT:1068345/C1/2> molten glass is delivered from one part of the spout than from another. This may be effected by providing heaters (11) at the centre of the spout, or by providing a tweel 2, the lower edge of which has an inverted V-shape (Fig. 4, not shown).  Alternatively, the spout itself may be shaped (Figs. 5 and 6, not shown).  Thus the greater mass of glass delivered centrally from the spout causes a displacement outwardly in the heel.  The heel is also limited by the shape of the wall 8 and tiles 9.  In Fig. 7 is shown an embodiment where glass is delivered at 29 and forms a heel 13 against a wall 8 having an end tile 30 so shaped as to have a central point 32 which is nearer the glass delivery area than is any other part of the wall. The shape of the walls 33, 34 causes a continuous transverse displacement of the glass in the heel.  As a further alternative, the molten glass may be taken away from the heel continuously in a direction away from the direction of advancement of the glass ribbon on the bath.  This is effected by drawing off a second ribbon of glass in the opposite direction to that advanced along the bath.
