Patent GB-868338-A (GB)
Title: Method of producing alkali metal terephthalate
Inventor: TAKAGI EIICHI
IPC: C07C51/41
Filed: 1959-05-05
Abstract: Alkali metal terephthalates are prepared by shaping into granules having a shortest dimension of at least 1 mm., a mixture of at least one alkali metal salt of phthalic, isophthalic or benzoic acid and a heavy metal catalyst and bringing the granules into contact in a reaction zone with carbon dioxide gas at 300-500 DEG C. and normal or high pressure.  The granule may be a sphere, tablet, cylinder, squared cylinder, pellet, bar, ring, tube, splinter, perforated block or any other irregular shape and may be prepared by kneading the salts and catalyst with a little water and passing the mixture through a shaping device to give granules having a preferred smallest dimension of 3-15 mm.  The catalyst may be cadmium, zinc or lead or their oxides or salts. The process may be worked continuously by feeding the granules in one end of a reactor, passing the carbon dioxide in counter current and withdrawing granules of alkali metal terephthalate from the other end.  Terephthalic acid may be obtained by dissolving the granules obtained by a batch or continuous process, in water, filtering off the catalyst and acidifying the filtrate. In examples: (1) potassium benzoate, cadmium carbonate and potassium iodide are moulded into cylinders 4 mm. x 7 mm. and heated at 400 DEG C. and 30 Kg/cm2 pressure in a batch process, (2) potassium phthalate, cadmium carbonate and potassium iodide are moulded into tablets 3 mm. x 6 m.m. and heated at 410-20 DEG C. and 30 Kg/cm2 batch process, (3) potassium benzoate, cadmium carbonate and potassium iodide are moulded into cylinders 6 mm. x 12 mm. and heated at 430 DEG C. and 20 Kg/cm2 in a continuous process.  Reference has been directed by the Comptroller to Specifications 744,721, 747,204, 762,448, 762,644, 777,497 and 777,609.

Patent GB-708739-A (GB)
Title: Improvements in or relating to the refining of hydrocarbon oils
IPC: C10G21/00
Filed: 1951-07-03
Abstract: Hydrocarbon oils are freed from asphalt, and from those constituents of the oil which form coke when the oil is subjected to catalytic cracking, by contacting the oil with a chemical compound of at least one of the elements having an atomic number from 24 to 28 (namely, Cr, Mn, Fe, Co and Ni), either concurrently with, or prior to, treatment with a de-asphalting agent, and thereafter separating the precipitated material from the oil.  The de-asphalting agent is essentially a hydrocarbon liquid and suitable de-asphalting agents are the light hydrocarbons containing from 2 to 4 carbon atoms in the molecule, such as propane or butane.  The chemical compounds mentioned are preferably water-soluble inorganic salts of the metals enumerated. These salts may be employed in the form of acidic aqueous solutions, the acidity being due to the salt or to the addition of acids, particularly the mineral acids (i.e. hydrochloric, nitric, phosphoric or sulphuric acid).  Specific salts mentioned are ferric, ferrous, nickel, chromic, cobalt and manganese chlorides; ferric bromide; nickel acetate; ferric, chromic, nickel and manganous nitrates; ferric, ferrous, nickel, chromic, manganic and manganous sulphates; and mixtures of these.  Steel mill pickle liquor, which is an aqueous solution of ferrous sulphate containing sulphuric acid, may also be used.  In the examples, residual petroleum oils are heated with anhydrous ferric chloride and then propane-de-asphalted. The refined oil may then be catalytically cracked at 500 DEG C. using a silicaalumina catalyst, while the asphalt removed in the propane-de-asphalting may be blown (alone or mixed with other asphaltic materials) with an oxygen-containing gas, the ferric chloride retained in the asphalt acting as a blowing catalyst.

Abstract: 873,108. Nuclear reactors. MULLARD Ltd. Aug. 17, 1959 [May 16, 1958], No. 15881/58. Class 39(4). An emergency shut-down circuit for a nuclear reactor comprises an ion chamber responsive to the neutron flux level of the reactor, an A.C. source for polarising the chamber and providing a reference voltage, and means for comparing the output of the chamber with the reference voltage. In the Figure a transformer 2 fed from an A.C. mains or from a square wave supply has a secondary winding of which one end is connected through a screened cable to one electrode of an ion chamber 5 and the other end is connected through condensers 6 to the other electrode of the chamber. This forms a bridge circuit, the two halves of the transformer winding forming two arms of the bridge, and condenser 6 and ion chamber 5 forming the other two arms; the balance of the bridge can be adjusted by potentiometer 10 and an output is taken from -terminals 8, 9 to an amplifier 11 and phase sensitive detector 12 to which the A.C. source is also connected, the output of the detector serving normally to energise the polarised relay 13. Under normal conditions the relay 13 remains energised but if the reactivity of the reactor rises the output of the phase sensitive detector falls and ultimately reaches a value where the relay is no longer energised, and the reactor shutdown control apparatus is then operated. Under any likely fault conditions such as failure of the A.C. supply, of the transformer, or of the condenser 6, the circuit will fail to safety and de-energise the relay.
