Title: Improvements in the reduction of oxide ores
IPC: C21B13/00
Filed: 1925-08-10
Abstract: 248,633. Dyer, Y. A. Aug. 10, 1925. Extracting.-A process for reducing iron oxide ores consists in placing the ores in a furnace, generating carbon dioxide outside the furnace, passing the carbon dioxide into the furnace and there converting it into carbon monoxide which then acts on the ore to reduce the latter. The ore is arranged in the furnace in beds with alternate layers of carbonaceous material which effects the conversion of the carbon dioxide to carbon monoxide. The ore is fed into the furnace 10, with alternate charges of coke and limestone. The carbon dioxide is generated in a producer 14 provided with a vertical baffle 15 forming a. main portion 16 in which fuel is burned and a smaller passage 17 down which the combustion products are forced by a blower delivering air, preferably preheated, through a main 18 and tuyeres 20. The gas produced passes through a passage 23 to a belt 24 and thence into the furnace 10 through ports 25 near the hearth of the furnace. A forehearth 28 with a tap hole 30 is provided to collect the molten metal. The carbon dioxide from the producer in passing through the lowest layer of fuel in the furnace is converted to carbon monoxide, lowering the temperature, and reduces the ore above to metallic sponge. When the layer of fuel has burned away, the hot carbon dioxide comes into contact with the spongy iron, melting it, and allowing the next layer of coke to descend to the hearth.

Title: Improvements in or relating to secret radio or like signalling systems
IPC: H04K1/04
Filed: 1939-07-13
Abstract: 531,150. Secret transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 13, 1939, No. 20435. Convention date, Aug. 31, 1938. [Class 40 (iv)] Inverted speech or inverted speech side bands are obtained by phase-modulating a carrier of (say) 60 Kc. at 5 Kc. with a peak deviation (2.4 radians in the case assumed) such that the carrier is suppressed, modulating (phase or preferably amplitude) the resulting side frequencies with the 0 ... 5 Kc. speech band and selecting the upper side band of the lower and the lower side band of the upper of the two first order side frequencies. These are in effect lower and upper side bands with the frequencies inverted of a 60 Kc. wave and are supplied with such a wave to the line or to a rectifier. The modulating operation may be performed in different ways and a frequency multiplying stage may be used to derive a 60 Kc. wave modulated to a deviation of 2.4 radians from a 15 Kc. wave modulated to a deviation of .6 radians. When the inverted band is used to modulate a transmitted carrier the latter may be given a frequency wobble at (say) 20 cycles to give further secrecy. In one arrangement, Fig. 4 (not shown), a 15 Kc. wave is phase modulated with the products of the modulation of a 5 Kc. wave with the 0 ... 5 Kc. speech band, the resulting currents are multiplied in frequency by 4 and the inverted side bands are filtered out. The filters may pass the two unmodulated first order side frequencies for the deviation of a de-modulating wave at the receiving end. In a modification, Fig. 7, a carrier wave is phase-modulated with a 5 Kc. wave at 14, the modulation products are multiplied in frequency at 18 and the resulting waves are modulated at 12 with the 0 ... 5 Kc. speech band. An unmodulated carrier is derived by frequency multiplication from the original wave at 16 and is passed with the inverted side bands falling on each side of it to a rectifier 28 for transmission by wire or radio Re-inversion at the receiving end is performed by similar apparatus. In a further modification, Fig. 6, two phase-modulated 15 Kc. and 5 Kc. waves are multiplied in frequency at 18, 18<SP>1</SP> and modulated at 12, 12<SP>1</SP> by the 0 ... 5 Kc. speech band, the arrangement being balanced so that in the absence of speech there is no output.

[Also in Division G2] In a method of processing photographic material the material is moved from one processing tank to another along a path which has at least one vertical portion and another portion with a horizontal component, the material being moved at a faster speed along at least part of said vertical portion than along said other portion. Figs. 1 and 2 show a device wherein endless chains 1, 2 run over wheels 3, 4 and 5, 6 respectively, wheels 3, 5 being driven synchronously by sprockets 7, 8 over which a chain 9 runs driven by a variable speed motor 11. A bar 14 is mounted on the chains 1, 2 by pins 12, 13. The bar 14 has supports 15 for suspension elements 16 for film strips 17. A stop 18 on the bar 14 is mounted so as to engage a lever 19, pivoted at 20 and normally held against a stop 22 by a spring 21, when the pin 12 arrives at point A, so as to cause an arm 23 on the lever 19 to actuate a microswitch 24 which causes the motor 11 to run at reduced speed. When the pin 12 arrives at point B the microswitch reopens and the motor 11 runs at its normal speed. As shown in Fig. 3, a constant speed motor 27 with electromagnetic couplings 30, 31 associated with gears 32, 33 and 35, 36 may replace the variable speed motor 11 of Fig. 1. In this case the microswitch 24 is normally as shown in Fig. 3 so that coupling 30 is energized and the drive is through gears 32, 33. When the microswitch 24 is actuated coupling 30 is deenergized and coupling 31 energized: the drive is then through gears 35, 36 giving a reduction in speed of six to one.

Class 39(1) tin a betatron-started synchrotron in which a magnetic core portion saturates at the end of the betatron period, the magnetic core is provided with an additional winding carrying a direct current, whose value is so adjusted that in consequence of the direct current flux produced in the core, a desired condition of resonance is obtained for the main windings during the starting up of the apparatus; the direct current is decreased as the alternating current energization of the main winding builds up. As shown, D.C. windings 37, 38 are in series with a regulable resistance 51. When the apparatus is started a movable blade 66 is caused by the weight 67 to close the contact 63. The direct current motor 55 is thus energized to drive the switch blade 53 of the regulable resistance 51 to the right so as to secure maximum direct current in the windings 37, 38. As the main A.C. voltage rises and the main windings,23, 24 approximate a state of resonance, a selsyn device 69 rotates the blade 66 so as to open the contact 63 and close the contact 62. The motor 55 then drives the switch blade 53 in the opposite direction so as to insert resistance 51 into the D.C. windings 37, 38, until eventually, these windings are disconnected from the D.C. source when the blade 53 reaches the left hand contact of the resistance 51. Specifications 574,812 and 702,193 are referred to. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 702,193.
