Title: Improvements relating to a process and apparatus for the homogenisation of molten gas
IPC: C03B5/187
Filed: 1970-03-19
Abstract: 1284495 Homogenizing molten glass COM. PAGNIE DE SAINT-GOBAIN 19 March 1970 [25 March 1969] 13264/70 Heading C1M Molten glass is homogenized by dividing a stream of the glass into a plurality of separate threads, imparting an abrupt change of direction to the threads and laminating the mass of glass produced by the recombination of the threads between two spaced surfaces situated adjacent one another. As shown in Fig. 1, molten glass 1 from a feeder 2 enters a bowl 3 of refractory material with a circular opening 4 in its base which is substantially closed by a disc 5, on a shaft 6, pierced by holes 7 so that the glass flows through as separate threads. The lower surface of disc 5 forms one of the two surfaces and the other may be formed, (1) as in Fig. 1, by the top surface of a disc 8 also on shaft 6 and rotating with disc 5, (2) by a disc 8 on a separate shaft (9) passing through a hollow shaft 6 so that the discs 5 and 8 may be rotated in the same or opposite directions and at the same or different speeds, (3) the base (10) of the feeder channel, which may have a raised portion directly under disc 5, (4) an inwardly projecting base portion of the bowl 3 giving a reduced orifice 12, as in Fig. 5, either integrally formed or by a wearing ring 11 forming the orifice 4, the fixed surface and reduced orifice 12. Preferably the surfaces are no more than 30 mm apart and the surfaces, or one of them, are of refractory metal or alloy, e.g. chrome-nickel refractory steel, molybdenum or a metal coated with platinum. When both are of metal, they may be connected to a source of electric current to heat the mass of glass between them. More than one set of disc and surface may be provided in a single feeder. To compensate for loss of head in the flow of glass, vanes may be formed in the lower face of disc 5 and/or the upper face of disc 8, or the holes 7 may be inclined. The process is of particular use when colour or other additives are being incorporated into a base glass.

Title: Improvements in or relating to the manufacture of nitric acid
IPC: C01B21/46
Filed: 1964-03-31
Abstract: <PICT:1046415/C1/1> Nitric acid of 50 to 70% by wt. concentration is manufactured by absorption in water or nitric acid of NO2 from cooled nitrous gases obtained by the catalytic oxidation of NH3 by a process in which the nitrous gases are cooled, oxidized and absorbed in succession, the cooling of the nitrous gases being carried out by passing them through at least 2 spaced-apart layers of water or nitric acid, the space between the layers being such that the depth of liquid in the cooling layers is at least a third of the distance between the layers so that, in the passage from one layer to the next, substantial reduction of the partial pressure of NO2 in the nitrous gases, due to substantial oxidation of the nitrous gases and absorption of NO2 so formed in the coolant liquid, is avoided. Referring to the Figure, the hot nitrous gases enter, by pipe 1, the bottom of compartment a (the cooler or condenser) and are cooled by the layers of liquid maintained on the bubble plates 4.  The nitrous gases then pass through pipe 9 into the oxidizer compartment b equipped with bubble-cooling plates 4 which are spaced further apart than those in a, so leaving free spaces 12 wherein oxidation of nitric oxide, with air introduced by pipe 11, occurs.  The nitrous gases pass through pipe 18 into the absorber (which is the upper compartment c of the column) having bubble-cooling plates 4 and free spaces 12; air for oxidation of the nitric oxide liberated in c enters by pipe 24. Absorption water enters by pipe 25 and acid condensate from the lowest part of a is pumped by 22 through pipe 23 and is hence utilized as absorption liquid.

Abstract: 950,731. Thermo-electric devices. BOUCHER & CO. Ltd. June 24, 1960 [April 27, 1959], No. 14229/59. Heading H1K. In a thermo-electric device in which the thermo-electric elements are arranged in a row, thermally conductive elements being inserted between adjacent thermo-electric elements to form hot and cold junctions alternately, the thermally conductive elements are in the form of plates having outside portions lying outside said row, the hot junction outside portions extend in one series of aligned peripheral locations, and the cold junction outside portions extend in another such series, and when viewed endwise of the row, the two series of outside portions do not overlap. As shown, Fig. 1, elements 10, 11, respectively, of N-type and P-type bismuth telluride or other semi-conductor material, have their ends rebated to accommodate heat-conducing plates 16, 18, of e.g. copper, which form hot and cold junctions respectively with the semiconductor elements. The elements are otherwise mutually insulated by strips 21, e.g. of mica, and the junctions are strengthened by fillets 24 of solder, e.g. bismuth and tin. The assembly is compressively stressed by endplates 22 (Fig. 2) of insulating material clamped by tie-bolts 23, and enclosed in a housing 22a of acrylic resin. The plates 16, 18 may be shaped as shown in Fig. 2, the former being disposed for heat dissipation at the rear of, and possibly outside, a refrigerator cabinet, while the latter are disposed within the cabinet, e.g. in an ice-making compartment, the assembly being fixed to a structural member of the refrigerator 26 by means of brackets 25. In the modification shown in Fig. 3, the plates 16, 18 are interleaved with the semi-conductor elements, the latter and the parts of the plates proximate thereto being invested in a thermally and electrically insulating material 27. The plates 16, 18 may project from the assembly otherwise than from opposite sides thereof, thermal feed-back being prevented by spacing or by interposing a barrier of thermally insulating material between the sets of plates. The location of a junction portion of a thermo-electric element within a socket or cavity in a laminated heat-conductive plate is mentioned, as is the application of the invention to thermo-electric batteries.
