Patent GB-997666-A (GB)
Title: Sulphation of reduced product of oxidised starch and its methyl ester
Inventor: NITTA YOSHIHIRO
IPC: C08B31/18
Filed: 1961-07-19
Abstract: The sulphate of the reduced product of oxidized starch is made by oxidising starch so as to convert the primary alcoholic groups therein to carboxyl groups, reducing the simultaneously formed keto-groups back to secondary alcoholic groups, and sulphating the resultant reduced product.  Oxidation and reduction may be effected by known procedures using e.g. nitric acid, or nitrogen dioxide for oxidation, and sodium borohydride, sodium amalgam, or hydrogen in presence of a catalyst for reduction. The product of the reduction step may be esterified to form the methyl ester, which is then sulphated.  The sulphation may be effected by reaction with chlorosulphonic acid in absence of a solvent, or in presence of a solvent such as formamide, dimethyl formamide, acelamide or pyridine. The sulphated product may be converted to an alkali metal salt by reaction with alkali.  The sulphated product, or its alkali salt may be isolated by precipitation in ethanol, and purified by dialysis or fractional precipitation. The product is thought to contain units of glucuronic acid, 2- or 3-sulphated glucuronic acid, and 6-sulphated glucose.  Aqueous solutions of the product have blood-anticoagulant activity, cholesterol-reducing activity, and lipaemia cleaning activity (see Division A5).ALSO:Injectable aqueous solutions having blood anti-coagulant activity, cholesterol-reducing activity and lipaemia cleaning activity contain the sulphate of the reduction product of oxidized starch, or methyl esters or alkali salts thereof. The sulphate is made by oxidizing starch so as to convert the primary alcoholic groups therein to carboxyl groups, reducing the simultaneously formed keto-groups back to secondary alcoholic groups, and sulphating the resultant reduced product (see Division C3).

Title: Improvements in or relating to apparatus for photographic optical projection
Inventor: HARRISON GEOFFREY BOND
IPC: G03B21/20
Filed: 1954-03-19
Abstract: 766,776. Photographic copying optical systems. ILFORD, Ltd. Feb. 22, 1955 [March 19, 1954]. No. 20705/56. Divided out of 766,775. Classes 97(1) and 98(1) A photographic transparency is illuminated by a substantially parallel beam of light obtained from a small light source and an image is projected by an objective lens, at least one secondary beam of light being obtained from the source by a mirror and directed through the transparency in a direction not to pass through the objective lens unless deviated by the transparency. In the form shown the transparency is illuminated by a lamp 11 with condenser 14. The beam 13 from the lamp passes through the objective 16. Secondary light rays, such as 19, are reflected through the transparency by a frusto pyramidal arrangement of plane mirrors 18. The system 'helps to neutralize the effect produced by scratches on the image formed by the beam 13. The relative intensities of the main and reflected beams may be controlled by varying the-aperture of the objective by a diaphragm or by a grey filter in the main beam. The Provisional Specification also contains the subject matter of Specification 766,775.

Title: A method of isolating a leaking radiator for use where single or multiple radiators are used
IPC: F01P3/18
Filed: 1943-12-11
Abstract: 570,194. Cooling radiators for aircraft. GREEN, A. S. ASTLEY, T., and BIRCHENOUGH, R. Dec. 11, 1943, No. 20752. [Class 64 (iii)] [Also in Group XXIX] Any one of a number of radiators M for cooling the circulating fluid of aircraft motors, is automatically removed from the circulating system if the pressure therein drops through damage &c., to prevent leakage. Each radiator has a valve box L. N on the inlet and outlet pipes, connected by a bypass tube I, branched into a higher position so that no flow occurs through it until the valves move to shut off the connections with the radiator. The valves are operated when the engine is running, by means of flexible rotatable cables 0, P, moved by an appliance A actuated electrically when, by reason of loss of pressure in any radiator, the needle of a pressure gauge E makes contact with a stop pin completing a circuit from a dynamo D. To enable the radiators to function on starting, the circuit, though closed on the gauge E until pressure builds up, is broken through contacts on the throttle lever assembly, which are only closed when the lever S is moved from the partially-closed starting position shown. A warning lamp B indicates the actuation of the valves. The actuating appliance A comprises a solenoid, Fig. 3, which when energised, pulls a connecting rod 5 so that a pin escapes from the inturned part of a slot 10 on a disc so that the disc, with the spindle 26 to which the cables O.P are attached, can rotate by virtue of the pressure of a spring in a tube 7. Resetting is effected by hand.

Title: Improvements in the extraction of phenol, phenol homologues and other hydroxy aromatic compounds from tar oils and mineral oils
IPC: C07C37/00
Filed: 1930-07-09
Abstract: Aqueous alkaline solutions of phenols, phenol homologues and other hydroxy aromatic compounds occurring in tar oils and particularly in tar oils which are obtained from vertical retorts and from low-temperature processes of coal distillations and also tars from mineral oils such as cracked mineral oils are subjected to distillation under a pressure substantially less than atmospheric pressure to remove volatile impurities.  The phenols are then liberated by known processes such as the addition of sulphuric acid or carbon dioxide, separated from the aqueous liquid and fractionated at appropriate temperatures and pressures. The distillation may be accompanied by oxidation or reduction which may be effected by the addition of oxydizing or reducing agents to the aqueous alkaline solution or oxidation or reduction may be effected before or after the distillation in which case they may also be carried out by electrolytic means.  The tar oils may be subjected to heat treatment prior to extracting the phenols with caustic soda.  In the example a sodium cresylate solution obtained by washing tar oil with aqueous caustic alkali is allowed to settle and then boiled vigorously in a vacuum pan; the refined sodium cresylate can be decomposed by known processes and distilled.

Abstract: A stable liquid composition is recovered from an ungelled polychloroprene latex foam containing zinc oxide and alkali silicofluoride by a process which comprises dispersing said foam in an aqueous medium containing a buffering agent capable of removing zinc ions and, as stabiliser a surface-active agent which is non-ionic or which ionises to give an organophilic anion.  The recovered liquid composition may be mixed with new polychloroprene latex, zinc oxide, soap, and carbon black and re-used for the manufacture of sponge rubber.  The buffering agent which is capable of removing zinc ions may be an alkali carbonate, borate, including tetraborate, phosphate, sulphite, oxalate, ferrocyanide, ferricyanide, or chromate.  The non-ionic surface active agent may be a reaction product of polyethylene glycol with an aliphatic alcohol having more than 6 carbon atoms, with an aliphatic acid having more than 8 carbon atoms, or with a phenol.  The ionisable agent may be one having the general formula R-SO3M where M represents an alkali metal, hydrogen, or ammonium, and R represents an organic radical containing at least one group having more than 8 carbon atoms.  Many such surface agents are specified. The recovered liquid may be creamed by means of ammonium alginate, pectin bodies, Irish moss, or locust seed or carob bean gum.

Abstract: Hexa-organo distannoxanes (i.e. bis(triorganotin)oxides) of formula R3Sn-O-SnR3 where R represents an aliphatic, cycloaliphatic, aromatic or aliphatic-aromatic radical are prepared by refluxing a mixture of R3SnCl with an aqueous dispersion of a hydrolysing alkali and an inert organic solvent which forms an azeotrope with water and is insoluble or only slightly soluble in water, and removing the water added and the water formed by azeotropic distillation.  Specified organic solvents include petroleum ether, benzene, dipropyl ether, di-isopropyl ether and methyl ethyl ketone.  The alkali may be sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium oxide, sodium carbonate or bicarbonate.  The radical R may be a C1-C8 alkyl radical, or a phenyl, tolyl, cyclohexyl or benzyl radical.  It is preferred to carry out the reaction at a temperature below 100 DEG C., and also to pass the azeotrope into a separator in which the water is separated allowing the solvent to flow back into the reaction vessel.  The salt formed in the reaction is filtered off and the solvent removed from the filtrate by evaporation leaving the bis(triorganotin)oxide as residue.
