Title: Interrupting or switching arrangement for high frequency circuits
IPC: H01P1/12
Filed: 1946-01-25
Abstract: 607,094. Modulating apparatus. STANDARD TELEPHONES & CABLES, Ltd. Jan. 25, 1946, No. 2538. Convention date, Aug. 19, 1944. [Class 40 (v)] High-frequency oscillations are distributed to or collected from a number of aerials or other circuits in turn by a sector-shaped rotary member moving past a ring of conductors connected to the respective aerials &c., and serving to couple them to a central conductor. As shown in vertical section in Fig. 4, and in cross-section along 5-5 in Fig. 5, the conductive sector 29 moves past a ring of four conductors 39 and couples thein in turn to a central axial rod 12. The rods 12, 39 are of half a wave length, and each is thickened at the end opposite to that at which sockets 22, 47 are provided for the feed lines. The sector 29 is separated by gaps from the remainder of the outer cylinder 24, and is connected to the inner cylinder 11 by flat radial members 30, 31 which line up with gaps 27 dividing the sector and the inner cylinders into two axiallyspaced halves. An intermediate cylinder 23 moving with the main,body is gapped at 32 to accommodate the live radial members 30, 31. The cylinders turn on ball bearings 35, 36 in a box or casing 4 fitted with shields 48. When the live sector 29 is opposite one of the rods 39 each half of the rod induces currents in the outer surface of the sector, and the radial members 30, 31 acting as a balanced line convey the energy to the inner surface of the inner cylinder 11 and to the axial rod 12. At the mean operating frequency, closed quarterwave sections are formed by the inner surface of the sector 29 and the outer surface of cylinder 23; and also between the inner surface of the cylinder 23 and the outer surface of the inner cylinder 11. Leakage currents are thus prevented at the mean operating frequency. The Specification discusses the relative values of the surge impedances of these quarter-wave lines necessary to obtain good impedance matching over a range of frequencies.

Title: Improved method of reducing ores
IPC: C21B13/14
Filed: 1927-01-31
Abstract: 291,822. Fairweather, H. G. C., (Nybergs Grufaktiebolag). Jan. 31, 1927. Tunnel furnaces; air and gases, supplying.-In the reduction of ores, especially iron ores, in which the ore loaded in carriages is fed through a tunnel furnace, the ore is first fed through a preheating and roasting zone where it is desulphurized and strongly heated by combusting a combustible gas with an excess of air, and then into a pre-reduction zone in which reduction by means of a current of reducing gases is begun and finally into a final reduction zone separated from the pre-reduction zone where it is subjected to the action of gases containing carbon monoxide, the gases therefrom being regenerated outside the said zone in recarbonizing furnaces, and the excess of gas being wholly or partly supplied to the reduction zone and then combusted in the roasting zone. The carriages c containing the briquetted ore are passed through a preheating zone C, a roasting zone D, and a pre-reduction zone E, combustible gas being supplied by a pipe T and an excess of preheated air by the pipe F. The ores are heated in the zones C, D to a higher temperature than is necessary for reduction so that the ore can deliver heat to the gases in the reduction zone. In the zone E, which is separated from the final reduction zone 0 by a shutter X, the ore is reduced to ferrous oxide and then, the shutter X being raised, is passed into the zone O where it is reduced by a current of carbon monoxide, which passes from one or other regenerating furnace P<1>, P<2> through a heater S<2> and a pipe G into the zone O and flows in counter-current to the ore. The gas flowing into the zone E by the pipe T is also heated in a heater S<3> on its way from the furnaces P<1>, P<2>. To assist the reductions in the zone 0, electric resistances may be inserted in the walls of the said zone. The reduced ore is then fed into cooling chambers N, which are separated from the zone 0 and each other by shutters y<i>, y<2>, y<3>, the first chamber being cooled by air passing through a pipe a from which the heated air is supplied to the pipe F. The gases from the zone 0 leave by a pipe H and pass through a heater S<1> to one or other of the regenerating furnaces P<1>, P<2> which are filled with incandescent fuel. The supply of gas to the furnaces is controlled by a valve L, the supply of air by a valve Q, and the supply of gas to the zones E, 0 by a valve R. The gas is forced through the zone 0 by a fan M. In a modification, the reducing gas is supplied at the beginning of the zone O and flows in the same direction as the ore, and the reduced ore is cooled by a water spray, the steam generated being removed by the circulating gases and passed therewith to the furnaces P<1>, P<2>. The ore may be mixed with pulverulent fuel such as charcoal or sawdust.
