Title: Apparatus for measuring the volume and weight of a liquid flowing through a pipe
IPC: G01F1/90
Filed: 1959-05-22
Abstract: 914,812. Measuring fluid flow. NISTRI, R. May 22, 1959 [May 31, 1958], No. 17592/59. Class 40 (1). [Also in Group XXVI] A flowmeter for measuring the weight of a liquid which flows through a pipe 2, Fig. 1, comprises a turbine 5 rotated by the flow, a magnet on the shaft generating pulses in a coil 8, which are amplified and applied to a pawl-and-ratchet counter 21, Fig. 2, the rotational output of which represents the volume which has passed. This value is corrected for changes of density in a variable gear 23 to which the correction is applied by a motor 22 controlled by a bridge circuit consisting of four resistors. Resistor 13 is adjusted manually to a value corresponding to the specific gravity of the fuel at 15‹ C. ; resistor 16 is temperature-sensitive and is immersed in the liquid where it flows through the meter; resistor 15 is insensitive to temperature and resistor 14 is driven by motor 22 to balance the bridge when the temperature varies from the normal 15‹ C. The motor 22 is controlled by a relay generator 19. The output from gear 23 represents the weight of the flow in the pipe. This is converted into an A.C. frequency in alternator 24, amplified at 25 and the cycles are counted by a second pawl-and-ratchet mechanism 26. The rotational output is used to drive the counter 28. If the flow exceeds the capacity of the meter to register it, a valve 3 may be opened to allow a known proportion of the flow to by-pass the meter.

Title: Improved process for refining vegetable fibrous material
IPC: D21C9/12
Filed: 1931-06-18
Abstract: In refining or bleaching vegetable fibrous materials by treatment with a solution of hypochlorous acid or its salts, the hydrogen ion concentration of the solution is maintained within the limits pH 4,5 to 8, preferably by the addition of one or more buffers.  The treatment may be preceded or followed by alkaline treatment. According to the examples, (1) a bleaching solution is prepared by treating bleaching powder ("calcium chloride") solution with soda solution, and is brought to pH 6,6 by addition of sulphuric acid and a buffer solution comprising monopotassium and disodium phosphates; beech-wood sawdust is left in the solution at atmospheric or slightly raised temperature, yielding a white product free from lignin; (2) sodium hypochlorite ("sodium chloride") solution is brought to pH 5,6 by treatment with sulphuric acid and a phosphate buffer solution; the solution may be used to bleach soda cellulose, sulphite cellulose, or cotton, and if the bleached material is subjected to alkaline treatment, a refined cellulose suitable for artificial silk manufacture is obtained; (3) flax yarn is treated with dilute soda solution at 90-100 DEG  C., washed, and bleached in a hypochlorite solution ("chlorine lye") brought to pH 6,8 by addition of a phosphate buffer; the material is then boiled with dilute soda solution, treated again with the bleaching solution, washed, treated with a dechlorinating agent, washed and dried; (4) cotton fabric is bleached and after-treated as in example 3.

Patent GB-892720-A (GB)
Title: Selective conversion of mixed olefins to organoboranes
IPC: C07C7/148
Filed: 1959-05-26
Abstract: Mixtures of unsaturated hydrocarbons are selectively converted into primary organoboranes with simultaneous separation of internally ethylenically unsaturated hydrocarbons from alpha ethylenically unsaturated hydrocarbons by reacting diborane with a mixture of internally and alpha ethenically unsaturated hydrocarbons, and separating the unreacted internally unsaturated olefines from the primary organoboranes, said diborane being used in the stoichiometric or less than the stoichiometric amount required to react with the alpha ethylenically unsaturated hydrocarbons to form triorganoboranes.  In general, the reaction is conducted at between 0 DEG C. and 150 DEG C. with temperatures between 25 DEG C. and 50 DEG C. being preferred.  The reaction may take place at atmospheric pressure or pressure up to 50 atmospheres. Diluents or solvents such as hydrocarbons, ethers, thioethers, nitroalkanes, nitroaromatics, and tertiary amines are specified. The unsaturated hydrocarbons will contain up to 30 carbon atoms, preferably up to 10 carbon atoms. Particularly preferred mixtures are those containing any one or all of the a -olefines: ethylene, propylene, 1-butene, 1-hexene, and 1-pentene and any or all of the internal olefines- 2-butene, 2-pentene, 2-hexene, 2-octene and 2-decene.  The mixtures can also contain other ingredients, such as hydrocarbons or substituted hydrocarbons, which are inert to diborane.  The organoborane product can be oxidized and hydrolyzed with alkaline hydrogen peroxide to produce the corresponding alcohol.  In examples, a mixture of 1-hexene and 2-hexene is reacted with diborane and the organoboron product converted to 1-hexanol with a small amount of 2-hexanol; a mixture of 1-pentene and 2-pentene gives essentially tri-n-pentyl boron; a mixture of C8 olefines gives tri-n-octyl boron which is converted to primary octyl alcohol.

A textile finishing process which comprises treating a textile material with an aqueous liquor of an isocyanate group-carrying compound and further with a silica sol, the isocyanate group-carrying compound being formed by reaction of a compound of M.W. 500 to 6,000 containing at least two hydroxyl groups per molecule with a polyisocyanate or its bisulphite addition product. The hydroxyl group-containing compound of M.W. 500 to 6,000 may be chosen from polyalkylene ether glycols such as polyethylene, polypropylene polybutylene or polyhexylene glycol; polyalkyl ether polyols e.g. polyalkyl ether triols such as the addition copolymers of ethylene oxide or propylene oxide and trimethylol propane, polyesters such as those obtained from aliphatic dicarboxylic acids e.g. succinic, adipic, sebacic or maleic acids, and polyhydric alcohols such as ethylene glycol, diethylene glycol, propylene glycol, butane diol and neopentyl alcohol. The polyisocyanates may be aliphatic or aromatic diisocyanates or triisocyanates such as that formed by reaction of 3 moles of hexamethylene diisocyanate and 1 mole of water. The silica sol, which has a particle size of 10-50mÁ, and contains 10 to 30% by weight of silica may be added to the treating liquor in a concentration range of from 0.3 to 5g/lt. The isocyanate group carrying compound may be present in a concentration of 0.5 to 5g. per litre of treating liquor. The treating liquor may also contain an emulsion stabiliser, which may be a fatty alcohol sulphate or a paraffin sulphonate at a preferred concentration of 0.05 to 0.2g. per litre of treating liquor or may be a polymer or copolymer from a vinyl or divinyl monomer at a preferred concentration of 1 to 3g. per litre of treating liquor. An electrolyte, which may be an alkali metal or ammonium salt of an inorganic or organic acid, may be added to the treating liquor at a concentration of 2 to 10g. per litre after the liquor has been allowed to act on the textile material. The process comprises agitating the textile material in a liquor ratio of from 1:6 to 1:50 in the aqueous liquor containing the isocyanate group-carrying compound and preferably the emulsion stabiliser, adjusting the pH to 4 to 6, adding the silica sol, allowing further action on the textile and then adding the electrolyte for further action. The process gives the textile resistance of abrasion, creasing, pilling and soiling and improved hand and treatment of wool gives a wash-fast felt-free finish.
