Title: Improvements in or relating to the reduction of iron oxide
IPC: C21B13/08
Filed: 1955-03-23
Abstract: 768,018. Iron manufacture. FREEMAN. H. March 23, 1955 [April 9, 1954], No. 8396/55. Class 72 Sponge iron is produced by introducing into a furnace hardened porous iron oxide pellets and finely divided carbonaceous fuel which has a low hydrocarbon content and which when burned will form an infusible residue which will not sinter at the reduction temperature, the amount of fuel being in excess of that required to reduce the iron oxide completely to iron and to convert the carbon, dioxide evolved largely to carbon monoxide and the fuel and residue being such as to prevent the pellets striking together, providing an oxidizing atmosphere at the feed end of the furnace by supplying air sufficient only to produce carbon monoxide and the amount of heat necessary to reduce the iron oxide, maintaining a non-oxidizing atmosphere in the remainder of the furnace length, advancing the pellets and the fuel concurrently with the gas flow in the furnace and cooling the resultant mixture in a non-oxidizing atmosphere. In the arrangement shown, the iron oxide with a binder is pelletized in a rotary drum 11 and the pellets are dried in a tunnel dryer 112 and hardened in an air roasting column 112a. The hardened pellets are then mixed at 113 with 40 per cent by weight of anthracite coal fines and the mixture is fed together with a metered quantity of preheated air from a line 37 to a rotary furnace 15. The pellets are reduced at a temperature of 1900-2100‹F. in the furnace and the reduced pellets are cooled under a CO/CO 2  atmosphere in a water-cooled extension 17 of the furnace. The reduced mixture is discharged from the end 18 of the furnace and the sponge iron is separated from excess carbon by screening or magnetic separation and is crushed to powder. In alternative arangements, the reduction may be performed in a tunnel furnace with a continuously moving conveyer-type hearth or in a Herreshoff multiple hearth furnace. Lime, hydrated lime, limestone or dolomite may be added to the furnace charge to absorb any sulphur evolved from the fuel and small amounts of alkali metal or alkaline earth metal carbonates or sodium aluminate may be added to the charge to increase the carbon monoxide concentration in the furnace. Up to 7 per cent by weight of iron powder may be added to the iron ore to be pelletized to promote self-roasting of the pellets.

Abstract: 1,211,259. Sewage treating vehicle. D. WICKHAM & CO. Ltd. 23 April, 1969 [21 Feb., 1968], No. 8477/68. Heading B1D. A lorry 123 carries a floculant tank 117 from which floculating agent is delivered by a pump (124) to a mixer 116, where it meets sewage sludge drawn from a primary settling tank at a sewage works, through inlet duct 114, macerator 115 and pump (120), the floculated sludge passing to the open tank 111 of an inward flow rotary disc filter, one disc being shown at 112. The lorry is driven round to small sewage works where permanent equipment of this kind would not be economical. The filter discs are internally divided and rotate to connect each sector in turn to two vacuum outlets, leading to pump 118 which delivers filtrate to tank 122, from which it is returned to the sewage works by a pump (144) responding automatically to level changes in tank 122. Solids are removed from the disc by scrapers and/or by a blast of compressed air delivered from tank (137), fed by compressor (135), the blast being released by a valve which is opened by a solenoid as the sector in question comes into communication with the air line (138). Solids are directed by shields 129, 131 on to shoots (141, 142) which discharge directly on to another lorry or on to a conveyor. Additional pumps (148, 149, 152) deliver fractions of filtrate from tank 122 to cool compressor (135) and seal vacuum pump 118, to dilute the incoming sludge in duct 114 and to dilute the floculating agent (Fig. 4, not shown). In Figs. 1 to 3 (not shown) recirculated filtrate passes through the vacuum pump to ensure constant flow of liquid therethrough.

Title: Improved signal separating means
IPC: H04N9/87
Filed: 1964-03-02
Abstract: 1,026,892. Colour television. AMPEX CORPORATION. March 2, 1964 [April 4, 1963], No. 8718/64. Heading H4F. The invention relates to separating a composite colour video signal into its luminance and chrominance signal components by means including a parallel resonant circuit so that they can be separately processed and then recombined in a summing amplifier for reproduction. As shown, the composite signal is applied to input terminal 30 and passes via emitter follower 34 to a parallel resonent circuit 20 which includes resistor 22 fixed inductance 24, fixed capacitance 26, variable capacitance 28 and variable inductance 42. Capacitance 28 and inductance 42 are adjusted so that circuit 20 resonates at the frequency of the colour burst signal, i.e. the impedance of circuit 20 is high for the chrominance signal. Thus the chrominance signal passes along lead 56 to the colour processor 14 and the luminance signal passes through inductances 24 and 42 to a grounded base amplifier transistor 46, emitter follower 52 and luminance processor 16. In processing circuit 16 the blanking and synchronizing signals are clipped and reconstituted and in processor 14 the colour signal is reblanked, the processed signals then being added for subsequent transmission or broadcast. For a composite colour video signal whose colour burst signal has a different frequency a standards conversion circuit which comprises transistor 58 and switch 60 is utilized. To turn-off the chrominance channel, e.g. in the absence of a proper colour burst signal, a signal received from a colour killer circuit 19 is applied through voltage divider 64, 66 and 68 to the base of transistor 70 which is connected across variable capacitor 28.

Title: Improvements in or relating to pressure reducing valves
IPC: G05D16/10
Filed: 1954-03-30
Abstract: 761,160. Fluid-actuated valves. BENDIX AVIATION CORPORATION. March 30, 1954 [April 13, .1953], No. 9307/54. Class 135. A pressure-reducing valve comprises a valve body 10, Fig. 1, having inlet, outlet and return ports 11, 12, 13 respectively, a fixed two-part sleeve 16, 17 and a piston valve 26 slidable in the sleeve and urged by a spring 32 towards the outlet port 12 and its fully open position. The sleeve part 16 is formed at its ends with counterbores 16a, 16b mounting the sleeve part 17 and a spring-loaded dashpot piston 45 respectively and intermediate its ends with inlet ports 21. Annular recesses 24, 27, Fig. 2, in the sleeve part 17 and the piston valve 26 respectively are shaped and piston valve ports 25 inclined so that the momentum force of the fluid flowing through the valve is reversed in direction to assist the spring 32 in opposition to the outlet pressure acting on the right-hand end of the piston valve. This momentum force increases with increased flow rate through the valve so that increased assistance to the spring overcomes in part the objection to the increasing rate of the spring as the valve piston moves towards closed position. Sudden movement of the valve in the opening direction is prevented by the dashpot piston 45, movement of the latter being restricted by slow leakage of the fluid around the piston 45 and a notch 26b in the valve piston. Instead of a falling output pressure with increasing flow rate which is usual, the valve maintains a substantially constant output pressure for. all rates of flow through the valve and the output pressure may even rise with increasing flow rate. A venturi passage adjacent the outlet port 12 increases the pressure at the outlet and on an increasing rate of flow through the valve the difference in pressure at the two ends of the venturi also increases so that the valve opens wider at higher flow rates than would otherwise be the case. On the occurrence of an excessive pressure in the outlet radial ports 30 in the valve piston are uncovered to connect the outlet port 12 with the return port 13.
