Patent GB-1004027-A (GB)
Title: Coating
IPC: C10K1/18
Filed: 1964-05-26
Abstract: 1,004,027. Coated sheet material. A. E. STALEY MANUFACTURING CO. May 26, 1964 [July 22, 1963], No. 21732/64. Heading B2E. A smooth grease-resistant coated flexible sheet is produced by applying an aqueous solution of amylose containing from 1-20% by weight of amylose to a surface which is not water-absorptive, e.g. roll applicator 3, transferring the coating to the flexible sheet 5 while the amylose is in an ungelled state and while the flexible sheet is moving at a rate of from 50-2,500 feet per minute, immediately smoothing the coating, e.g. by air knife 9, before the amylose coating composition gels, and drying the coated sheet. The flexible sheet may be paper or paperboard and the coating may weigh at least 1 pound per 1,000 square feet. Other sheets specified are films or coatings of polyethylene, e.g. corona discharge treated polyethylene coated natural Kraft paper, polypropylene, polyethylene terephthalate, polyvinyl chloride, polyvinylidene chloride, polyvinyl fluoride and aluminium foil. The aqueous solution of amylose may have a maximum Brookfield viscosity of 400 cps. measured at the temperature at which the coating is applied. The aqueous solution of amylose may be at a temperature of from 60-100 ‹C. The amylose may be the separated fraction of whole starch and comprises no more than 15% by weight, e.g. 6-12% of the aqueous solution and the amylo-pectin content of the amylose may be less than 20% by weight. Excess amylose treating material may be removed from the coated paper in the smoothing operation, e.g. by air knife or rotating rod, recovered and possibly recycled. The coating may be smoothed by passing the coated sheet between a surface, e.g. roll 7, and a blast of air from knife 9 with the coated side of the flexible sheet exposed to the blast ; the coated sheet is then dried. One or more additional coatings of amylose may be applied prior to or after the drying step. The coating may include plasticizers, e.g. glycerol, sorbitol, choline chloride, polyvinyl alcohol and/or 1.2,6-hexanetriol. The paper may be coated with a composition comprising clay and the alkaline hypochlorite-oxidized starch.

Abstract: 358,615. Fourdrinier paper-making machines. DEHN, F. B., 103, Kingsway, London.-(Beloit Iron Works; 815, 2nd Street, Beloit, Wisconsin, U.S.A.) July 21, 1930, No. 22000. [Class 96.] In the formation of a paper web on the wire of a Fourdrinier machine in which a shaking movement is imparted to the wire an initial fibre formation is allowed on a portion of the wire near the breast roll which is relatively free from lateral movement and thereafter a vigorous shaking action is applied during the remainder of the passage of the wire to the couch roll. The point of application of the shaking movement is closer to the breast roll for heavy stock than for lighter stock, and the intensity of the action and the points of application of the shaking force are regulated in accordance with the weight of the paper being made.

Filed: 1972-05-12
Abstract: 1419956 Knitting machines COURTAULDS LTD 11 May 1973 [12 May 1972] 22330/72 Heading D1C A V-flat machine includes on a support moving with the cam boxes at least one presser foot which is reset to an appropriate position during overrun and return at the ends of its traverse. The presser feet 11-12; 13-14 of a two system machine are carried by arms 27, 28 pivotally mounted between plates 15, 18 of the support 9. The V-shaped upper ends of the arms cooperate with pins 57, 58 fixed to a rack slider 51. The slider 51 is reciprocated by a further slider 22 via pinions 66, 68. The slider 22 carries an abutment 61 (62 not shown) at each end for striking fixed stops. A further rack slider 25 carrying abutments 72 (74) is in driving communication via pinions 77, 82, 83 with slider 22. Towards the right-hand end of a traverse an abutment (62) on slider 22 strikes a stop, thereby moving the slide to the left relative to the support. Consequential movement of slider 51 bring the arms 27, 28 to an upright position. Mean while abutment 72 on slider 25 has passed below a catch. On return of the support, movement of slider 25 to the right relative to the support swings the arms until they strike stops 38, 40 thereby bringing feet 12, 14 into operative position. Abutment 72 is released from the catch by abutment 85, or a cam track (102 Fig. 2 not shown) fixed to the support. Feet 11, 13 are similarly brought into operative position at the left-hand end.

Abstract: 1,036,678. Submerged tanks. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 26, 1965 [May 28, 1964], No. 22388/65. Headings B7A and B7M. [Also in Divisions B8 and E1] A buoyant reservoir for liquids, e.g. petroleum products obtained from a submarine oil-field, comprises an elongate vessel 5 (Figs. 1 to 3, not shown) which normally floats in a substantially vertical attitude and is secured by mooring chains 6 provided with anchors 7, the submer. sion depth of the vessel being regulated by a liquid, e.g. water, 16 lodged in a ballast chamber 9. Oil is delivered to the reservoir through a pipe 13 and a conduit 12 at the upper end of the vessel, water 14 within the vessel being displaced by the incoming oil 15 through one or more openings 8. Liquid may be continuously fed to the chamber 9 through a pipe 21 containing a flow-control valve 22 whilst liquid is withdrawn from the chamber by a pump 24 through pipes 25, 26 and a flow-control valve 27, said valves being adjusted so that the quantity of liquid in the chamber is changed in accordance with changes in the amount of oil contained by the vessel to keep the depth of submersion substantially constant. The valves 22, 27 are controlled by a control device 20 receiving signals from a recording device 19 which depend upon the movement of a float 17 at the surface of the water of floatation whilst oil is pumped into, or out of, the reservoir. The vertical attitude of the reservoir may be partly effected by lodging one or more blocks of solid material 10 in the lower end of the vessel. Oil is withdrawn from the reservoir through a pipe 28, and the chamber 9 communicates with the atmosphere through a plurality of tubes 11. The reservoir may carry a rotatable element 31 to which a ship, e.g. an oil-tank vessel, 33 can be secured whilst oil is conveyed thereto, or therefrom, through a hose 36 supported by a derrick 35 which is mounted above said element. Alternatively, the reservoir may carry a turntable 37 (Figs. 4, 5, not shown) provided with a capstan 45 to which a ship can be attached whilst oil is transferred thereto, or therefrom, through a hose 43 connected to the vessel 5 by pipes 40, 41 and a movable coupling 42, the hose being rendered buoyant by a plurality of floats 44. The reservoir may also be provided with a landing platform (not shown) for helicopters.

The threads 3, 4, may be of cotton, linen, hemp, paper &c. and each turn of the locking thread 4 may comprise two or more strands. The wrapping 3 may be double. The wrappings may be treated with an inflammable asphalt composition to which is applied a flame-retarding composition such as pitch. Armouring or a non-metallic sheath may also be applied.

Title: Therapeutic composition
IPC: A61K31/16
Filed: 1953-08-18
Abstract: A stable solution of a thiobarbiturate for parenteral injection comprises a substantially water-free solution of a thiobarbiturate in a parenterally acceptable water-miscible organic solvent containing a water-free alkali metal alkalizing agent providing an alkali metal concentration substantially in excess of that required to maintain the said thiobarbiturate in solution as an alkali-metal salt.  The preferred solvents are ethyl alcohol, propylene glycol and mixtures thereof.  Specified alkalizing agents include sodium ethoxide, anhydrous alkali metal hydroxide, the alkali metal salts of monoethanolamine and the reaction product of sodium and propylene glycol.  The compositions may be prepared by dissolving a calculated amount of metallic sodium sufficient to provide the excess alkalinity in an excess of pure ethyl alcohol in an inert (nitrogen) atmosphere, adding propylene glycol and the thiobarbiturate as the sodium salt, and making up to the final volume by addition of solvent.  In an example finely divided sodium is dissolved in absolute ethyl alcohol, and propylene glycol added to the so-formed sodium ethoxide solution. Sodium ethyl-(1-methylbutyl)- thiobarbiturate is dissolved therein to give a 25 per cent w/v solution.
