Filed: 1919-02-14
Abstract: 144,751. British Oxygen Co., and Bray, S. W. Feb. 14, 1919. Hydrogen.-In the iron-steam process of making hydrogen, the waste gases of reduction which have been fully spent in passing through a retort or bench of retorts, but which still contain reducing gases, are treated for the removal of steam and some water vapour, carbon dioxide, and sulphur dioxide and other sulphur compounds, and then passed to another retort or bench for effecting reduction of the charge therein; the waste gases may be passed into the furnace setting, or discharged into the atmosphere. The process may be carried out with three sets of retorts or benches; while the first set is making hydrogen, the second set is receiving water-gas completely to reduce the charge therein, and the spent gases are treated as above described and passed to the third set; at the next stage, the second set is making hydrogen, the reduction of the charge of the third set is completed by water-gas, and the spent gases are after purification passed to the first set; and so on. To purify the spent gases, they are first passed through a scrubber packed with marble, coke, &c. and down which water trickles and removes the sulphur compounds, then passed through water or potash solution to remove carbon dioxide, and finally through a tubular condenser to remove steam and water vapour; or after passage through the first scrubber, the gases may be passed through a condenser, and afterwards through a purifier charged with lime to remove sulphur dioxide. Specification 17951/09, [Class 1 (i), Chemical processes &c.], is referred to.

Abstract: 883,415. Circuits employing bi-stable magnetic elements. POSTMASTER GENERAL. May 2, 1958 [Feb. 4, 1957], No. 3789/57. Class 40 (9). An output pulse is produced in a lead L2 by way of a transistor VT1 when a direct current in a lead L falls below or exceeds predetermined limits, the direct current being applied to windings A on ferrite cores X1, X2, having rectangular hysteresis loops which are periodically driven to the set condition by pulses α2 and have output windings C connected to the transistor. Core XI is reset and produces an output pulse when the direct current exceeds a predetermined value, while core X2 is periodically reset by reference current pulses α1 in winding D which act in oppositionto the direct current in winding A. Core X2 therefore produces an output pulse in its winding C if the direct current is below a given value. The α1 and α2 pulses are applied alternatively to the cores so that the initial set conditions are re-established, the reference current pulse α1 being applied over a further core X3 and a transistor VT2.
