Title: Improvements relating to the Production and Utilisation of Magnesium Chloride.
IPC: C01F5/32
Filed: 1916-09-30
Abstract: 109,996. Bailey, G. H., Foster, G. W. A., and British Aluminium Co. Sept. 30, 1916. Magnesium chloride is made by treating a mixture of carbon and magnesite or magnesia at a temperature of 750-800‹ C. with chlorine, or mixed gases containing chlorine, preferably dry and free from oxygen. Chlorine for this purpose may be obtained by electrolysis of magnesium chloride, or waste gas, for instance that remaining from the production of bleaching powder may be used Excess of carbon is advantageous. For instance, 84 parts of magnesite or 40 of magnesia may be mixed with 12 of carbon or carbonaceous material and with tar or pitch. Briquettes formed from the mixture are heated to 1000-1200‹ U. in an inert or reducing gas, magnesite being converted into magnesia. In one method, the briquettes are cooled out of contact with air, broken, and placed in a vertical or inclined retort B. As shown, the retort B branches from an electrolytic cell A of steel lined with firebrick, &c. Both the cell and the retort may be heated by gas, the best temperature for electrolysis being 650-700‹ C. The electrolyte consists of a mixture of sodium and magnesium chlorides, with or without potassium chloride. Chlorine collected by a bell D around the anode E is conducted by a pipe k to the retort B, whence the magnesium chloride formed flows into the cell in the neighbourhood of the cathode M. This consists of a body of molten aluminium or other alloying metal, contained in a crucible c and connected by a graphite rod F surrounded above the metal by an insulating sheath j. A solid cathode and collector are substituted if pure magnesium is required. The cell is preferably covered. In a modified method, the blocks of magnesite and carbon are heated first in a muffle forming a continuation of the retort B, and then, without cooling, are transferred to the retort. The same gases may heat the muffle, retort, and cell successively; the carbon monoxide obtained may be used for this purpose. If magresium chloride is required, the cell acts only as a tank for receiving it.

Title: Improvements in or relating to thermionic valve circuits
IPC: H03K3/37
Filed: 1944-07-21
Abstract: 592,753. Valve relay and pulse generating circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 21, 1944, No. 14024. Convention date, June 19, 1943. [Class 40 (v)] In a circuit having two stable states dependent on current flow through a thyratron, a hard valve is so coupled to the thyratron that successive pulses of similar polarity applied to the hard valve causes the thyratron to strike and extinguish alternately. A positive pulse, applied to the grid of pentode 5 causes an increase in screen current and fall in potential. Due to the resistors 14, 15, 17, the cathode potential of thyratron 9 falls, causing the valve to fire, and after a short delay due to capacitor 18, the cathode potential rises, also the screen potential of valve 5. A succeeding pulse applied to the grid of pentode 5 causes a fall in anode potential of valves 5, 9, extinguishing the thyratron 9, the capacitor 18 maintaining the bias to prevent re-striking for a short interval at least until the pulse has ceased. The capacitor 18 discharges, the potential falling to its original value in preparation for the next pulse. Specification 542,927 is referred to.

Title: Improvements in or relating to flushing valves
IPC: E03D3/04
Filed: 1949-05-26
Abstract: 664,636. Fluid-actuated valves. JOHNS, S. O. May 26, 1949 [March 24, 1949], No. 14135/49. Class 135. A flushing valve comprises a unitary slidable main valve member 8 of, e.g. polyvinyl chloride, with metal reinforcements 26, 27 and a sealing lip 22, a tiltable pilot valve member 29 for releasing pressure from a chamber 9 to allow the main valve member to open, and passages 34, 36 communicating with the chamber 9 and so arranged as to accelerate the closure of the main valve member as it nears its seat 7. Thus, the passage 34 is always open but the passage 36 passes a flow only when the main valve member has moved below it or, as in the arrangement shown, has descended sufficiently to permit leakage upwardly between the valve member and a bore 14 in which it operates. Adjustment of the degree of valve opening is effected by part rotation of a spring-loaded push rod 37 to vary the height of an eccentric end 47 thereof which coacts with a sleeve 32 depending from the pilot valve member. The sleeve 32 is slidable on a rod 31 to permit both valve members to close if the operating handle 43 is not released after actuation. The rotary adjustment of the rod 37 is preserved by the interengagement of flats 49, 51 on the rod and in an opening of the housing.
