Abstract: 1,196,065. Liquefied gas storage containers. VEHOC CORP. 16 July, 1968 [21 Aug., 1967], No. 33840/68. Heading F4P. L.N.G. is stored under pressure and near its boiling point in a heat-insulated vessel 20a having no ullage space and vapour evolved due to heat leak together with expanded liquid is vented through a duct 34 leading to a drum 38 of sufficient capacity to accommodate said vented vapour and liquid and having sufficient ullage space to provide for expansion and vaporization due to normal heat leak in the drum itself which latter has a pressure relief vent valve 61 in a discharge stack 62. A plurality of vessels 20a to 20n are vertically mounted in a ship's hold and have access ducts 21a to 21n connected by relief valve 36a to 36n to the vent duct 34 and by liquid block valves 27a to 27n to an insulated liquid header 26 having one end leading to the drum 38 and the opposite end connectable to a shore liquidfill and emptying line 11 and a pump 12 to a tank 10. The storage vessels have further access ducts 22a connected by relief valves 35a to 35n to vent duct 34 and by block valves 31a to a main uninsulated vapour header 30 connected at one end to drum 38 and connectable at the other end to a shore line 13 and a compressor 14 to the vapour space of tank 10. Vapour block valves 31a-31n are each controlled by a liquid sensor 32a to 32n whilst the liquid block valves 27a to 27n are controlled by vapour sensors 28a to 28n. The liquid level in drum 38 is maintained below a predetermined height by means 49 which withdraws excess liquid, vaporizes it and discharges either through valve 61 and stack 62 or through a line 55 to the ship's engines or to a burner 59. To fill the vessels 20a-20n and with shore lines 11, 13 connected to headers 26, 30 a valve 48 in header 26 is closed, valves 23a to 23n and open as are valves 15, 16, 29, 33 and pump 12 is operated and liquid flows through open liquid block valves 27a to 27n to the vessels 20a to 20n whilst vapour is forced through open valves 31a to 31n, header 30 and line 13 to tank 10. When a given vessel, say 20a, is filled with liquid, the level reaches a sensor 32a which then closes the liquid block valve 27a, which it controls, and filling is completed when sensor 32n closes valve 27n. During the voyage valves 23a to 23n and 27a to 27n are closed but valve 48 and vapour block valves 31a to 31n remain open whereby expansion liquid in access ducts 22a to 22n gains access to the uninsulated header 30 where it is vaporized and carried through the vent header to the drum 38.

Abstract: 1,230,254. Wire-reinforced float glass. ERSTE DEUTSCHE FLOATGLAS & CO. OHG. G.m.b.H. 11 June, 1969 [14 June, 1968], No. 29561/69. Heading C1M.  In the manufacture of float glass, a wire inlay is introduced downwards into the glass strip when it is at a temperature of about 1050 C. by means of a wire inlay guiding means which is maintained clear of the glass surface and the surface of the glass downstream from the point of introduction is heated to ensure an even plane surface. As shown in Fig. 1, molten glass 1 is cast on to a bath 4 of molten tin 3 and in the first and hottest zone 3A spreads out to a glass strip 11 of width determined by side limiting bodies 5 of graphite which have a central hole (6) for the supply of cooling fluid which, if porous graphite is used, may be a protective gas or liquid tin to assist movement of the glass strip 11. In the midlde zone 3B, the tin is cooled by side cooling tubes (13) and bottom tubes 12 to maintain the glass at about 1050 C., the zone 3B being deeper than adjacent zones and with barriers 14 to ensure an even cooling. Above this zone, and set into roof 28 of the bath 4, is the wire inlay supply and guiding means comprising supply rolls 24, feed rolls 22, 23 and guide bodies 20, 21 all except the tips of the bodies 20, 21 being enclosed in a gas tight housing 26. After the wire inlay 10 is introduced into the strip 11, the strip passes to zone 3C where heaters 31 re-form the top surface of the glass which may otherwise show cuts from the wire inlay. As shown in Fig. 4, in zone 3B, the bodies 5 and deeper bath are replaced by a graphite barrier 41 with cooling tubes 40, the barrier 41 having projections 42 for limiting the width of the glass strip 11. The guide bodies 20, 21 are curved as shown and are provided with heat-insulated outer and bottom surfaces and are hollow with coolant flowed therethrough. To supply separate wires, the guides 20, 21 are replaced by double-walled guide tubes. The guides 20, 21 may be adjustably mounted to vary the height relative to the glass and also the inclination. As shown in Fig. 7, the body 20 may be replaced by a pair of guides 70, 71 with a space between through which hot protective gas via duct 75 is blown on to the glass strip 11 and which depresses the strip 11 and tin 3 below it to form a curve 74 so that the wire inlay 76 can be led into the strip 11 at the level required. In a further embodiment (Fig. 8, not shown), the wire inlay 76, led over guide body 21, enters the glass strip which is raised over a barrier (80), the top part (82) of which is of porous graphite and molten tin is pumped with a central hole (81) so as to pass through the barrier to give a layer (83) of tin below the raised glass layer (84). Reference has been directed by the Comptroller to Specification 1,157,406.
