Abstract: 389,449. Inductance and phasedifference measurements. KRIZIK, KABELOVNA A ELEKTROTECHNICK• ZAVODY, AKCIOVA SPOLECNOST, 34, Hybernskß, Prague. June 10, 1931, No. 16873. Convention date, June 10, 1930. Void [Published under Sect. 91 of the Acts]. [Class 37.] The Specification describes a method of employing an electrodynamic apparatus for measuring errors in transformation ratio &c. in current or voltage transformers. The differential apparatus DW is connected through the change-over switch P to the current loads ZA and the voltage loads ZV. A small phase regulator F is also connected to the change-over switch P. When measuring the current transformers, i.e. transformer X and comparison transformer N, the current coils of the apparatus DW are connected in opposition, and the current of the phase regulator introduced into the moving coil of the differential apparatus. This current also flows through the moving coil of the ammeter A, the fixed coil of which carries the secondary current of transformer N. Adjustment of the strength of the primary current by the ammeter A and phase regulator F yields a deflection giving the error of the transformation ratio or the angle error of the two transformers. For measuring the voltage transformers X<1>, N<1> the two coils of the differential apparatus DW are connected in series, and the phase regulator F is adjusted to give a measure of the transformation ratio error &c., the ammeter and milliammeter being cut out. The apparatus may be used in a zero method employing the bridge arrangement of the Schõring-Alberti method.

Filed: 1954-06-09
Abstract: Alkali-metal salts of carboxymethyl cellulose, in which the degree of substitution by ether groups in all the molecules of the cellulose ether is substantially the same, are prepared by intimately mixing purified particulate cellulose, a water-soluble etherifying agent containing a carboxymethyl group in the molecule and an alkali metal hydroxide in a three-component, two-phase liquid medium consisting of water, an organic liquid miscible with water and an organic liquid immiscible or substantially immiscible with water, both organic liquids being inert to the reactants of the mixture and non-solvents for the alkali metal salt of the carboxymethyl cellulose.  The cellulose may be in the form of cut fibres or may have been ground to powder.  The total liquid to cellulose ratio may be between 4 : 1 and 20 : 1, the optimum ratio with cut fibrous cellulose being about 11 : 1.  The ratio (on a weight/weight basis) of the water in the aqueous phase to the dry cellulose may be 0.03-3.4, preferably 0.24-0.85, at the beginning of the reaction.  The organic liquid miscible with water is preferably an aliphatic alcohol having 2-4 carbon atoms in the molecule, and the liquid immiscible with water preferably has a boilingpoint above 35 DEG  C. and may be benzene, toluene or xylene. In an example, 63 parts by weight of 60 mesh cotton linters, 317 parts of ethanol, 310 parts of toluene and 81 parts of 45 per cent aqueous caustic soda solution are mixed at 30 DEG  C. for 30 minutes, 35 parts of monochloracetic acid are added and the mixture is agitated for 70 minutes at 65 DEG  C.  The excess caustic soda is neutralized with glacial acetic acid and the product is filtered off, washed successively with 65 per cent and 92 per cent (by weight) aqueous ethanol and dried.  U.S.A.

Title: Process for the preparation of modified silica gels
Inventor: ACKER ELLSWORTH GEORGE
IPC: C01B33/146
Filed: 1964-04-24
Abstract: A silica gel containing a hydrous metal oxide is prepared by incorporating in a silica sol 2 to 6 weight per cent based on the silica content of the sol of a metal salt which can be hydrolysed to a hydrous oxide, gelling the sol, washing the gel with acidic water and activating the gel. The metal salt may be the bromide, chloride, iodide, sulphate or nitrate of germanium, zirconium, tin, hafnium, lead, thorium, or cerium or a basic aluminium salt. The amount of metal salt is preferably such that the gel contains 0.5 to 2.5% by weight of the hydrous metal oxide based on the weight of silica in the gel.  The silica sol may be prepared by the hydrolysis of silicon tetrachloride or tetrafluoride or ethyl orthosilicate or by the reaction of an alkali metal silicate and a mineral salt. The metal salt, in solution in the minimum amount of water, or as a liquid, is added to the sol, or the metal salt plus sulphuric acid may be added to sodium silicate. The mixture is allowed to gel for e.g. 15 to 30 minutes and the gel after ageing for several hours at 50-70 DEG  C. with water at pH 2.5-3.5. After drying and activation the total volatiles in the gel is no more than 7%. The gels show high absorptive capacity at low relative humidities (see Division B1).ALSO:A silica gel containing a hydrous metal oxide e.g. of Ti, Ge, Zr, Sn, Hf, Pb, Th and Ce, is prepared by incorporating in a silica sol 2-6% by weight based on the silica content of the sol of a metal salt which can be hydrolysed to a hydrous oxide, gelling the sol, washing the gel with acidic water and activating the gel.  The gel shows an increased adsorptive capacity for water at relative humidities below 30%, and is particularly useful for drying "Freon" (Registered Trade Mark) natural gas and air.

Abstract: 1,019,892. Automatic titration apparatus. COURTAULDS Ltd. May 11, 1962 [May 11, 1961], No. 17173/61. Heading B1X. [Also in Division B8] In automatic apparatus in which samples are repeatedly abstracted from a bulk supply of solution, the samples being titrated in vessel 1 with a reagent liquid, the reagent is generated as required by electrolysis of a salt solution in cell 3. The sequence of operations is controlled by an electronic controller 4 connected to electrodes 5 which measure a titratable characteristic, e.g. pH value, of the liquid in vessel 1. The solution to be estimated, e.g. an acid solution, is withdrawn from pipes 17, 17<SP>1</SP> each time controller 4 rotates disc 14 until the passage in the disc is in line with pipes 17, 17<SP>1</SP> where they pass through stationary discs 13, and further rotates the disc 14 until the passage is in line with pipes 18, 18<SP>1</SP>, when a measured quantity of distilled water from line 18 forces the sample, contained in the passage of disc 14, into vessel 1 via pipe 18<SP>1</SP>. Disc 14 is then rotated until the passage is in line with pipes 19, 19<SP>1</SP>, where it is cleansed with water. At the same time, controller 4 starts stirrer 7, actuates pump 25 to fill cell 3 with neutral salt solution, and closes switch 26 so that electrolysis takes place in cell 3. The alkaline reagent formed in the cell passes into vessel 1 via line 11. When the liquid mixture in vessel 1 reaches a predetermined pH value, controller 4 alters switch 26 so that resistance R is incorporated in the electrolysis circuit whereby the end-point of the titration is approached more slowly. At a second predetermined pH value of the mixture in vessel 1, controller 4 opens switch 26 whereby the final flushing of the alkaline solution from cell 3 is just sufficient to complete the titration. At the end-point, the controller records the current consumed by cell 3 as shown by meter 27. The controller now stops stirrer 7, and actuates pneumatic ram 12a which lowers tube 12 into vessel 1 to withdraw the bulk of the liquid therefrom. After a predetermined time-interval, tube 12 is retracted. The sequence of operations may then be repeated immediately, or after a predetermined time.
