Patent GB-222147-A (GB)
Title: Improvements in method of producing nitrogen hydrogen mixture for the synthetic production of ammonia
IPC: C01B3/02
Filed: 1924-09-22
Abstract: 222,147. Synthetic Ammonia & Nitrates, Ltd., (Assignees of Jahn, F. W. de). Sept. 21, 1923, [Convention date]. Hydrogen; nitrogen. - In the production of the nitrogen-hydrogen mixture for ammonia synthesis, a mixture of nitrogen, hydrogen and carbon monoxide is first prepared in which the nitrogen is present in less than the ratio of 1 : 3 with respect to the hydrogen, this gas is then treated catalytically with steam, and the final adjustment of the nitrogen content is effected by combustion of an oxygen-containing gas therewith or with another combustible gas. Air and steam in regulated quantities are passed through incandescent coke and the resulting gas mixture, after cooling and purification, is stored in a gas holder. Thence it is forced by a pump 2 through the pipe 48<a> into a preheating system 47, 49, 51, 47a, 49<a>, 47b and then through the pipe 52 into converters 39, which are shown as operating in parallel. In the converters the carbon monoxide content of the gas mixture reacts with steam previously introduced in measured quantity by the pine 48 at point A and the converted gas returns through the heatinterchanging system 47b, 44. 47a, 45 and 47, leaving the system by way of pipe 46 and condensers 4 to a gas holder 5. Instead of introducing the steam by pipe 48, some of it may be produced in situ by continually circulating water by means of pump B and pipe C through the first heat-interchanger 47, the remainder of the steam being introduced in regulated quantity by the pipe 48 into the second heat-interchanger 47a at point E. The deficiency in nitrogen is adjusted at the auxiliary burners 8. To this end, a measured quantity of the gas in pipe 48<a> is withdrawn by pipe 9 and introduced into the burners, while at the same time air is supplied to the burners by blower 6 and pipes 7, 7<a> in quantity slightly less than that required for complete combustion. The crude gas in pipe 48<a>, the gas after compression and purification, and the gas circulating in the ammonia synthesis system are constantly analysed and the gases introduced into the burners regulated in accordance therewith. Instead of crude gas withdrawn from pipe 48<a>, any other gas capable of combustion in the burners may be employed, provided that no objectionable impurities are introduced into the system. Also, the starting mixture of nitrogen, hydrogen and carbon monoxide may be produced by mixing different gases, for example, by adding producer gas or " blast gas " to water gas. Specification 120.546 is referred to.

Title: Improvements in or relating to the production of combustible gas
Inventor: RICHARDS ROBIN OWEN
IPC: C10J3/00
Filed: 1954-07-30
Abstract: 786,490. Gas manufacture. WOODALLDUCKHAM CONSTRUCTION CO., Ltd. May 24, 1955 [July 30, 1954], No. 22384/54. Class 55 (1). A method of producing a combustible gas comprises separately withdrawing from a twostage coal-water gas producing plant 1, Fig. 1, either simultaneously or alternately substantially hydrocarbon-free water gas and hydrocarbon-containing coal-water gas; passing the water gas through a separate coal carbonizing plant 2 as carrier gas and mixing the coalwater gas with the gaseous products of the coal carbonizing plant as diluent gas. As shown, a coal-water gas plant 1 comprising a distillation zone 3 superimposed on a gasification zone 4 is operated cyclically. During the " blow," air is passed through grate 5 and ports 6 which are at the top of gasification zone 4. In the " uprun " saturated cool or moderately superheated steam is passed through grate 5 to form water gas in zone 4. This carbonizes the coal in zone 3 and the coal-water gas formed is passed into a foul gas main 8 to mix with the coal gas produced in retort 2. During the back-run, Fig. 2, highly superheated steam is passed from superheater 7 downwardly through zone 4 and the resulting water gas after cleaning and cooling at 9 passes to a relief gas holder 10 and the base of retort 2. The gas holder 10 delivers water gas to the base of retort 2 during the up-run and blow periods. In a modification, Fig. 3, in which the coal-water gas generator operates without a down-run, highly superheated steam, for example at a temperature of 800‹ C., is passed through grate 5. Part of the water gas produced in zone 4 is withdrawn through ports 6 and passed to the cleaning and cooling equipment 9 and to the relief gas holder. The remainder passes upwardly through the distillation zone 3 and the resulting coal-water gas is used as diluent for the coal gas produced in retort 2. In another embodiment the two methods are combined. During the up-run the water gas is divided as in Fig. 3 and during the back-run superheated steam is passed downwardly through ports 6 as in Fig. 2. In any of the embodiments the coal-water gas may be carburetted with oil before being added to gas from plant 2. Also the coal-water gas may be cooled and cleaned before being mixed with the coal-gas.

Title: Improvements in moulding machines for building blocks
IPC: B28B1/087
Filed: 1946-07-30
Abstract: 640,450. Moulding-machines for building- blocks. DANIELSSON, P. K. M. July 30, 1946, No. 22737. Convention date, July 30, 1945. [Class 87 (ii)] In a moulding-machine for building-blocks in which the mould is inverted on to a table for delivery, the table then moving down while the mould is held stationary and the moulded block is pressed out of the mould, the table is supported in its upper position by a spring device which is adjustable to vary the upward force on the table. As shown, a mould 1 fixed on a shaft 2 mounted in bearings on the machine frame 5 is rotatable through 180 degrees to the dotted line position over the delivery table 9. The table 9 is supported by a rod 10 vertically movable in a bracket 11 on the frame 5 and is urged upwards by a spring and lever system shown in Fig. 4. The lower end of the spring 13 secured at its upper end to the frame 5 may be connected to any one of a number of holes in a lever 12 or an arm 14 attached thereto, one end of the lever being pivoted to the frame at 15 and the other to the rod 10. The position of the spring 13 is adjusted so-that the weight of the moulded block will cause the table 9 to descend slowly, the increase in the tension of the spring 13 as this occurs being compensated by a decrease in the leverage exerted by the spring about the pivot 15, thus maintaining the upward force on the table substantially constant. The weight of the mould box 1 is largely balanced by a spring 4 adjustably connected to an arm 3 on or integral with the shaft 2. The mould box 1 although rotatable with the shaft 2 may be loosely mounted thereon to prevent vibration, if employed in the moulding operation, being transferred excessively to the machine frame. Alternatively, the mould box may be freely mounted on the shaft 2 and the arm 3 connected directly to the mould box, Two or more springs 13 may be employed, the associated parts being duplicated as necessary. A shoot 6 for the moulding material is provided and a filling box 7 pivoted at 8 to the shoot so that it may be swung out of the way of the mould 1 when this is inverted.
