Patent GB-268835-A (GB)
Title: Improvements in or relating to the indication at a distance of the direction of a magnetic field
Filed: 1927-04-04
Abstract: 268,835. Levy, L. April 3, 1926, [Convention date]. Earth inductor machines. - The direction of a continuous or alternating magnetic field or of electromagnetic waves is obtained by comparison, by means of an electro-dynamo-metric phase-meter, of the relative phases of the electromotive force due to an auxiliary field and of that emanating directly or indirectly from exploring elements placed in the field under investigation. In the apparatus shown in Fig. 1, a tetrapolar diphase rotor 3, disposed in a. horizontal magnetic field NS, and a frame aerial 19 subjected to the action of a magnetic field 20, the direction of which it is required to ascertain, are keyed on a vertical rotatable shaft 1. The two windings 4, 5 of the rotor are connected, through slip-rings 7 - - 10, to the two fixed coils 22, 23 of a phase meter 21, which are set with their axes at right angles. The frame aerial 19 is connected, through slip-rings 11, 12, 25, 26 and a detector-amplifier 33, to the movable coil 24 of the phase-meter. For determining the direction of an alternating high-frequency field, the frame aerial is preferably tuned by means of a condenser 34. The detector-amplifier 33 amplifies the high-frequency currents induced in the frame aerial 19 and provides a low-frequency current of a frequency equal to twice the number of turns per second of the frame and which passes through a maximum each time the frame is perpendicular to the field. Diphase current of the same frequency, but having a phase relation dependent on the direction of the field 20, is generated in the windings 4, 5. The position of equilibrium of the coil 24 of the pointer 35, therefore determines the direction of the magnetic field under examination. In the modification shown in Fig. the rotating frame aerial 19 is replaced by two fixed vertical frame aerials 36, 37 at rightangles, tuned by condensers 39, 38, which are preferably mechanically coupled. The frame aerials 36, 37 are connected to the grid-filament circuits of three- or four-electrode valves 41, 40, included in the plate circuits of which are the rotor windings 44, 43 of a diphase generator and the primary windings 47, 45 of two transformers. The secondary windings 48, 46 of the transformers are connected in series through a detector-amplifier to the movable coil 24 of a phase meter, the fixed coils 22, 23 of which are fed from the diphase windings 43, 44. In the phase meter, the coil 24 may be fixed and the coils 22, 23 movable.

Abstract: 435,417. Valve circuits for wireless reception. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Germany. March 24, 1934, No. 9249. Convention date, March 29, 1933. [Class 40 (v)] A detector for the high modulating frequencies, e.g. up to at least 100 kc. used in television is arranged so that the time constant of the grid capacity and leak resistance is less or equal to the period of oscillation of the minimum modulating frequency. A detector valve with the grid-lead-in at the top may be used to reduce the grid-cathode capacity and the coupling condenser is made as large as possible relatively to the grid-cathode capacity to maintain the efficiency while the total of the grid-cathode and coupling capacities is kept small to obtain the desired time constant. The carrier frequency may be effectively separated from the modulating frequencies in the detector output by the use of a push-pull detector, Fig. 3 (not shown), or, in the arrangement shown by utilizing the counter-phase potentials at the grid and anode of the detector. Adjustment of the tap 20 enables the carrier to be wholly removed from the output 14.

Producers; producer plant.- A gas-producer of the suction type is carried on a motor-vehicle and a gas purifying and cooling system is arranged beneath the frame or on the roof. while a water and air heating coil is arranged in the producer and a valve is provided which automatically stops all communication between the producer and the engine and air supply when the engine is stopped. Gas is led from the producer a, Fig. 3, through a dust-separating chamber p and then through pipes q on the roof or beneath the frame to the engine t. One of the pipes may contain a removable cage r filled with wood-wool or other filtering-material. The producer shown in Fig. 4 is provided with a coil l by which air and gas is heated prior to its entry into a chamber e at the bottom of the furnace. The funnel m by which fuel is supplied to the furnace contains a depending pipe n through which a poker can be inserted for stirring the fuel without its being necessary to push the poker through the whole mass of the fuel. The air and gas is supplied to the engine through the valve box shown in Fig. 5, in which the gas is drawn through the automatic lift valve z and the air through openings in the box controlled by a cylindrical valve y. Both valves are closed by springs and opened when required by wires, 8, 9. The engine draws the mixture past the butterfly valve 5 and its suction effect lifts the gas valve z from its seat. When the engine stops, the gas valve automatically closes so that air cannot enter the producer pipes and a good supply of undiluted gas is thus available for restarting. A water vaporiser u as described in Specification 130,754 may be used.

Title: Process for the direct production of magnesium in the fused state from ore
IPC: C22B26/22
Filed: 1945-04-16
Abstract: A process for obtaining magnesium in the liquid state by reducing ore in a furnace in vacuo and condensing the vapours evolved, characterised in that, for each charge of the furnace, a portion of the magnesium is obtained in the liquid state during a first phase, by operating in a low vacuum and keeping the condenser at a sufficiently high temperature, and in that during a second phase, by operating in a higher vacuum and decreasing the temperature of the condenser, the remaining quantity of magnesium contained in the ore is then obtained in the solid state.  This solid magnesium is subsequently fused, for instance by the heat supplied by magnesium vapours condensed as liquid during the reduction of the next charge e.g. by condensing the said vapours in the liquid state directly on to the solid magnesium.  In carrying out the process, when the furnace is recharged, the condenser contains crystalline magnesium deposited during the second part of the previous cycle of operations. Less than the maximum vacuum is created in the furnace and the condenser temperature is allowed to rise till conditions are such that magnesium condenses in liquid form.  In the second phase the vacuum is increased and the condenser is cooled till optimum conditions are obtained for the reduction of the ore and any magnesium evolved is condensed in the solid form.

Filed: 1917-07-05
Abstract: 119,485. Alexander, A. E., (Adams, A. B.). July 5, 1917. Hydrocarbons, cracking.-Hydrocarbon oils are cracked for the production of low-boiling hydrocarbons, gas, &c. by mixing them with steam, passing the mixture through a cracking-chamber, and then, at the exit of the cracking-chamber, bringing the products into contact with a finelyattenuated mass of catalytic metal. A burner supplied with a mixture of oil and steam also is described. In the cracking-apparatus, Fig. 1, steam generated in a coil H is led by a pipe 3 to an oil tank B. The mixture of oil and steam is forced through a pipe 4 to a heating-coil K, and thence through a pipe 6 and atomizer 5 into a cracking-coil L. The products, after passing over a mass X of platinum, palladium, nickel, or other catalytic metal, flow to a condenser M and scrubber N. The condensate is led to stills T and the gas is collected in a gasometer 13. Toproduce a maximum of fixed gas, a temperature up to 1600‹ F. and a minimum pressure are used; when hydrocarbons of low boiling-point are required, a temperature below 1100‹ F. and a pressure above 250 lb. per sq. in. are employed. The burner S for heating the apparatus is supplied with the mixture of oil and steam from the tank B by means of a pipe 17. The mixture flows through an annular gas-generating chamber 16, Fig. 2, at the exit from which is situated a coil of catalytic metal. The resulting gas is led by a pipe 18 to an expansion chamber 19 containing a mesh of catalytic metal, and is burnt at the burner tip. The flame passes through an aperture 33 in a cap plate 32, and is deflected by a plate 21 through annularly-arranged perforations 22 into contact with the walls of the generator 16 and thence upwardly into the furnace. The burner is started by burning alcohol in the cupshaped casing surrounding the burner tip. Air is supplied through ports 34. The catalyst X used at the exits of the cracking-coil L and the gas-generator 16 preferably consists of a spiral of wire arranged with its spirals decreasing in diameter in the reverse direction to the flow of the gases.
