Title: Improvements in and relating to a process for smelting oolitic ores and slimes
IPC: C21B13/14
Filed: 1925-09-16
Abstract: 240,165. Gredt, P. Sept. 16, 1924, [Convention date]. Extracting.-In a process for reducing oolitic &c. ores and slimes obtained from minette, the ore with the usual additions is treated in a reduction furnace having a series of rotating agitating members within a fixed casing, the speed at which the ore is passed through the furnace being regulated so that the, smelting furnace is charged continuously with reduced ore from the reduction furnace and the temperature of the heating gases being regulated by a temperature-regulating device so that the charge in the reduction furnace is kept at a temperature below the sintering temperature of the ore. The charge is fed into the reduction furnace A and conveyed therethrough by revolving arms B while being subjected to reducing gases from the smelting furnace D, which may be a blast or electric-furnace or any other furnace which may be tapped. The gases from the furnace D pass through passages C and through a temperature -regulating device (not shown) before entering the furnace. The charge may be preheated by the combustion in the upper part of the furnace A with a portion of the gases conveyed away from the reduction zone of the furnace A.

Title: Information Store
Inventor: AXFORD JOHN GILBERT
IPC: G11C11/14
Filed: 1968-05-16
Abstract: 1,164,788. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 16 May, 1968, No. 23283/68. Heading H3B. A storage arrangement comprises a succession of matrix planes A-F, Fig. 1, having common word lines W and bit/sense lines B, a read out pulse on a word line producing a train of output pulses in the sense line, one pulse from each matrix, as the read out pulse is propagated through successive matrices. Each pulse has a polarity determined by the bit stored in the matrix from which it is transmitted, and in the known arrangement shown the spacing of the output pulses depends on the position in each matrix at which each bit/sense line intersects the corresponding word line. This variable output spacing is avoided by using either of the wiring arrangements shown in Figs. 3 and 4, a pair of word lines W and bit/sense lines B being provided each of which is associated with one half only of the matrix planes P1-P8. With either of the wiring arrangements shown, and ignoring the end connections between successive matrices which contribute little to the delayed propagation of a read out pulse through the store, the effective path length between any pair of lines B and W from one intersection to the next is a constant, and this is the same for every location in the store at the intersections of particular word and bit/sense lines. The storage elements may be thin films.

Title: Improvements in or relating to thermionic commutating and the like devices for use in multiplex signalling and for other purposes
IPC: H04J3/16
Filed: 1929-08-02
Abstract: 319,758. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger, R. H.). Sept. 29, 1928, [Convention date]. Addition to 309,509. Multiplex signalling; copying and writing telegraphs.-The thermionic valve commutating- system described in the parent Specification for cyclically opening and closing a number of signalling channels is modified in various respects, and particularly by the addition of a spacing-channel which comes into operation whenever no signalling-channel is active. Fig. 2 shows a system involving three signalling-channels A, B, C and the additional spacing-channel S. Referring to channel A, when no signal is applied the grid of valve 7 is negative, no plate current is passing, and the condenser 17 is charged by the plate battery 31. A signal swings the grid positive, the condenser 17 discharges through the valve 7, and the voltage across a neon or other suitable lamp 21 rises to the flashing-point. This causes the grid of the valve 29, which has previously been passing plate current, to become negative. Owing to the resistance 33 in its plate circuit, its plate becomes more positive and consequently the grids of all the valves 39, 67, 69, 71, and 49 become positive, and tend to pass plate current. The valve 49 thus passes on the signal to an oscillator 57 energizing any suitable transmission system. The valves 67, 69, 71 have their plate circuits connected to resistances 133, 233, and 79 in the grid circuits of valves 139, 239, and 349 associated respectively with the two signal channels B, C and the spacing-channel S. These channels are therefore blocked until the neon lamp 21 is extinguished, and the grid of valve 39 again becomes negative. Either channel B or channel C will now take control of the transmitter, in the same way as described above for the channel A, the oscillators 157, 257 for these channels being uf different frequency from the oscillator 57. While any one of the signal channels A, B, or C is operative the spacing channel S is blocked by the voltage across a resistance 79 caused by the passage of current through one of the valves 71, 171, or 271. When all the signal channels are inoperative this current ceases, and the grid of the spacing-valve 349 becomes positive, and its plate circuit controls the transmitter through the oscillator 357. Further channels may readily be added to the system. The system may be applied to picture or facsimile transmission and television, or to multiplex telephony or telegraphy. It may also be used for combining signals received on a number of geographically separated aerials for the avoidance of fading or the reduction of static and interference. Illuminated signs may be controlled by associating each signal channel with lamps of different colours, the spacing channel being arranged to cut off all lamps.
