Abstract: Starch o-phthalate is made by heating granules of dried rice starch with phthalic anhydride in pyridine/dioxane.  Carboxyethyl starch is prepared by heating granules of dried maize starch with b -chloropropionic acid in alkaline butanol/benzene.  Hydroxyethyl starch o-phthalate is formed when granules of dried hydroxyethyl maize starch are heated with phthalic anhydride in the presence of sodium acetate, acetic acid and xylene.  2-Carboxy-5-nitrophenyl starch is obtained if granules of dried rice starch in alkaline butanol/xylene are heated with 2-chloro-4-nitrobenzoic acid. 2-Methyl-3-amino-5-sulphophenyl starch is produced by heating rice starch granules with 3-chloro-4-methyl-5-amino-benzene sulphonic acid in alkaline butanol.  2 - Carboxy - 4 - amino - 5 - sulphophenyl starch is made by heating maize starch granules with alkali and butanol, filtering and washing with benzene and the product heated with 6-chloro-3-amino-4-sulpho-benzoic acid in benzene.

Abstract: 1,091,095. Controlling the olefin concentration in desorbing and/or purging mediums. BRITISH PETROLEUM CO. Ltd. Oct. 20, 1966 [Nov. 4, 1965], No. 46754/65. Heading B1L. In a cyclic process employing molecular sieves to separate straight chain hydrocarbons from branched chain and/or cyclic hydrocarbons, in which process the circulation of desorbing and/or purging medium is effected, and in which process olefins tend to build up in the circulating medium to an equilibrium level, the olefin concentration is controlled by hydrogenating at least a proportion of the olefins. Preferably the purging medium is hydrogen, the desorbing medium is n-pentane, and the hydrogenation is carried out in the presence of a catalyst comprising either nickel supported upon sepiolite or cobalt and molybdenum oxides supported on alumina. The denormalised hydrogen fraction containing n-pentane and hydrogen together with olefins obtained from the purge stage passes from absorbers through line 1 to hydrogen separator 2 and thence to stripper 4 from where the final de-normalised product is removed as bottoms and the npentane and olefins as overhead offtake. The n-pentane and olefins are similarly stripped at 12 from the normal paraffins from the desorption stage. The n-pentane fed to drum 10 from strippers 4 and 12 is recirculated to the absorber, a portion being hydrogenated in reactor 17 and fed into the stripper 2 for removal of any hydrogen present in the hydrogenated n-pentane stream.

Abstract: 1369906 Olefin polymerisation catalysts PHILLIPS PETROLEUM CO 7 Oct 1971 [8 Oct 1970] 46792/71 Heading B1E [Also in Division C3] Silica-based hexavalent chromium-containing olefin polymerisation catalyst is prepared by a method which comprises forming a silica hydrogel by intermittent or continuous addition of aqueous alkali metal silicate solution to acid solution, aging the hydrogel, washing the aged hydrogel to remove alkali metal, forming a silica xerogel by removal of water from the hydrogel with the use of a watersoluble oxygen-containing organic liquid, impregnating the xerogel with chromium (VI) oxide or a compound convertible thereto upon calcination, and calcining the impregnated xerogel. The acid used in the preparation of the hydrogel may be a strong acid, for example sulphuric acid, or a weak acid, for example carbonic acid. The aged hydrogel may be washed with material selected from water, dilute acid solutions and ammonium salt solutions; specified ammonium salts are ammonium nitrate and ammonium salts of organic acids. The water may be removed from the hydrogel by repeated washing with the organic liquid or, when the organic liquid forms an azeotrope with water, by azeotropic distillation; specified organic liquids are n-propyl alcohol, sec-butyl alcohol, acetone, methyl isobutylketone, butyraldehyde, diisobutyl ether, ethyl acetate and isopropyl acetate. As exemplified, catalysts containing 1 weight per cent chromium (elemental basis) in the form of chromium oxide are prepared by a procedure wherein the silica hydrogel is formed from sodium silicate (water glass) solution and dilute sulphuric acid solution, the aged hydrogel is washed initially with ammonium nitrate solution and thereafter with water, the water is removed from the hydrogel either by repeated washing with acetone or by azeotropic distillation using methylisobutylketone or ethyl acetate, the silica xerogel is impregnated with a solution of t-butyl chromate in n-pentane and the impregnated xerogel is calcined at 1600‹F; comparison catalysts are prepared by a similar procedure modified in that either the sulphuric acid solution is added to the sodium silicate solution or the water is removed from the hydrogel either by spray drying or by azeotropic distillation using n-heptane or n-octaine as organic liquid.

Abstract: 1281538 Simulating a diode NATIONAL SEMICONDUCTOR CORP 25 Sept 1969 [4 Nov 1968] 47238/69 Heading H3T [Also in Divisions G3 and H1] A monolithic two terminal voltage regulator (Fig. 3) simulating a threshold diode comprises an NPN (or PNP) device 20 connected in series with a resistive element (here JUGFET 17) across the voltage source, the device being such that punch through from one junction (shown as emitter in Fig. 3) to the other occurs at a voltage below that required for avalanche breakdown of the one junction. Transistor 18 in shunt with this series arrangement has its collector connected to the " collector " of device 20 and has pinch resistor 21 as load, and a further transistor 19 of opposite type can be connected as shown to sharpen the characteristic. In operation, after device 20 starts to conduct, increase in the supply voltage pinches off FET 17 to switch on transistor 18 and then transistor 19 to provide a characteristic equivalent to that of a breakdown diode, the breakdown voltage of which varies linearly with temperature. Fabrication in a silicon wafer by planar-epitaxial techniques is suggested, the same diffusion serving to form the emitter of transistor 19, the bases of transistor 18 and device 20 and the channel of FET 17.

[Also in Division H3] A displacement transducer comprises a pair of elongated coils 13, 15 Fig. 1, in an air gap between which a vane 22 of electrically conductive material is movable. Field concentrating means are provided in the form of ferrite rods 24 and U- shaped bars 25, 26. The coils are connected in an oscillator circuit as shown Fig. 3, which is fed from a constant direct current source via terminals 18, 19. The oscillating condition of, and hence the effective resistance of the circuit, is dependent upon the vane position. When the oscillator is not oscillating it absorbs power and its effective resistance is small relative to the constant current source. When it is oscillating i.e when the vane has moved out of the gap the power consumption will be smaller and the effective resistance greater. The voltage drop across the oscillator input terminals 18, 19 which is said to vary linearly with movement of the vane, is taken as the oscillator output signal and provides an indication of the vane position. C21 acts as an H.F. block and C20 as a D.C. block. The vane may be mechanically coupled to a hydraulic valve for example. A casing 27 Fig. 1 may act as a magnetic screen.
