Title: Arrangements for deriving electric pulses of constant duration from pulses of variable amplitude
IPC: H03K7/00
Filed: 1947-01-28
Abstract: 620,868. Pulse shaping circuits. STANDARD TELEPHONES & CABLES, Ltd., and GRAYSON, H. Jan. 28, 1947, No. 2600. [Class 40 (vi)] In a circuit for deriving from input pulses, output pulses having a duration independent of the magnitude of the input pulses, the input pulses are applied in a positive sense to the grid of a valve 1, via a resistance capacitance network 9, 5. When a pulse is applied no change in grid potential, and hence anode current, occurs, the grid cathode potential being held near zero by grid current. The grid current charges capacitor 9 during the pulse, so that the grid goes negative when the pulse terminates, causing a drop in anode current which gives rise to the output pulse, this pulse existing until capacitor 9 has discharged sufficiently to allow grid current to flow again. In order to make this period independent of the charge on capacitor 9, the lower end of resistor 5 is connected to earth via a peak rectifying circuit 6, 10, which gives the valve a positive bias proportional to the magnitude of the input pulse, so that the extent to which capacitor 9 has to discharge before grid current starts to flow is varied inversely with the magnitude of the input pulse.

Title: Improvements in the process of direct reduction of iron ores
IPC: C21B13/00
Filed: 1924-02-01
Abstract: 210,795. Levoz, T. Feb. 1, 1923, [Convention date]. Extracting; purifying and refining.-Iron ores are intimately mixed with alkaline fluxes which melt at temperatures below 1000‹ C. such as fluorspar, soda, borax, potassium, bichromate, cryolite &c. for the purpose of melting the gaugues (enriched with silica and alumina) and just sufficient carbon for the reduction of the iron oxides, all in a fine state of division, the mixture being formed into briquettes which are charged into a furnace and the ores reduced solely by the heat produced by external heating agents such as the injection of powdered carbon, oils or electrical means. The product, a pig iron containing manganese and also 1 per cent of carbon as a maximum and 5 per cent of silicon as a minimum, is run into a reverberatory furnace, where it is heated and is maintained in the fluid state by a covering of aluminous slag formed by the addition of ferruginous bauxite to the charge. The product then passes into a second furnace, where by the action of heat the silicate of alumina in the slag is dissociated, the alumina being converted into aluminium, the resulting product being an alloy of iron, silicon, aluminium and manganese, without carbon or only slightly carburetted. This product is then passed into a third furnace and ore or hammer scale and fluxes of low-melting points added. The silicon and manganese are oxidized, and the aluminium volatilized, leaving the iron in the liquid state from which it is separated and run out into the atmosphere. To ensure that the melting charge contains at least 5 per cent of manganese, a sufficient quantity of manganese ores, it not present, should be added to the melting charge. Specification 214,648, [Class 51 (ii), Furnaces and kilns for applying &c.], is referred to.
