Patent GB-471847-A (GB)
Title: Improvements in or relating to the manufacture and treatment of cellulose derivatives
IPC: B04C9/00
Filed: 1937-02-24
Abstract: The process described in the parent Specification is modified by treating the dissolved cellulose ether or secondary cellulose ester with an agent containing or readily liberating an amount of free chlorine not exceeding 1 per cent of the weight of the cellulose derivative.  Another modification of the process of the parent Specification consists in treating the cellulose derivative while still in solution in the medium in which it has been produced, after that solution has been thinned by adding a diluent or solvent.  In an example, cellulose acetate solution obtained by reacting cellulose with acetic anhydride in presence of sulphuric acid and acetic acid is subjected to a ripening treatment and the solution is then thinned by adding aqueous acetic acid.  A concentrated aqueous solution of sodium bicarbonate is beaten into the solution to neutralize the catalyst.  Chlorine water in amount equal to 0,1 per cent chlorine based on the weight of cellulose acetate is added.  After several minutes, warm water is stirred into the solution until it is at the point of precipitation.  A large mass of water is then added and the cellulose acetate separates as fluffy fibres.  The product is washed and stabilized. Hypochlorites may be used instead of chlorine.  The cellulose acetate preferably while in solution may be treated with an anti-chlor such as a solution of borax.  It may be subjected to further bleaching with hypochlorite or peroxide after precipitation. The products may be used for making films, filaments, moulding powders, plastics, lacquers, blocks, tubes, and rods.  Ethyl, methyl, or benzyl cellulose, or secondary cellulose formate, acetate, propionate, or butyrate may be treated.

IPC: B24C3/06
Filed: 1974-02-07
Abstract: 1419474 Blasting HITACHI SHIPBUILDING & ENG CO Ltd 7 Feb 1974 [20 March 1973 26 Sept 1973] 05647/74 Heading B3D [Also in Divisions B2 and F2] A machine for abrasive cleaning of hull sections comprises an abrasive slinging device 1 having a hood 4 and a drive motor 2 for an impeller 3, an abrasive accommodating container 10 supported by the device 1 and communicating with the impeller chamber through a feed path 11, a tube 26 establishing communication between the interior of the upper portion of the container and the interior of the hood, a channel 27 opening to the upper portion of the container, and means 36 for producing air currents which flow from the interior of the hood through the tube 26 and container to the channel, whereby the abrasive particles slung against the surface to be cleaned and dust are returned to the container by air currents, the dust is separated and passed through the channel 27, and the abrasive is circulated for re-use. The impeller 3 is driven by an air motor 2 and slings abrasive at a surface 25 enclosed by the hood 4 which has a skirt 74 of rubber or the like surrounded by a brush 75. A handle 5 having a grip bar 6 is secured to the device 1, the handle having an on-off valve controlling the supply of air from a compressor tube 7 to a branch tube 8 and hose 9 leading to the motor. The container 10 is connected by piping 11 to an abrasive feed path 12 leading to the impeller, the path terminating in a laterial outlet 13, the flow of abrasive along the path and through the outlet being assisted by air pressure from nozzles 15 and 22 connected by hoses 20, 23 to the branch tube 8. The outlet 3 is in a cylinder 24 rotatably adjustable to control the position of the feed into the impeller. The hood 4 is connected by the tube 26 to a tangentially arranged opening 38 in the upper part of the container 10, the upper part also being connected through an orifice 40 in a plate 41 with a tube portion 32 which has a constricted passage 35 connected to a filter bag 28 and a nozzle 36 directed at the passage and connected by a hose 37 to the branch tube 8. The pressure from the nozzle 36 cause flow through the constricted passage 35 to produce a negative pressure in the upper part of the container so that abrasive and dust passing from the hood through tube 26 to the container are separated, the dust passing to the filter bag and the abrasive falling to the feed path 12. In another embodiment, the nozzle 36 and constricted passage 35 are replaced by a vacuum cleaner connected to the tube portion 32. To prevent abrasive being sucked into the air motor when the on-off valve is closed, the valve not only cuts off the supply to the tube leading to the air motor and the tube leading to the nozzles 15, 16 but also cuts off connection between the tubes. The machine may be used to clean the corner between a vertical surface 79b and a horizontal surface 79a and has a hood 80, Fig. 8, shaped to fit the corner, the machine being supported by adjustable wheels 93 engaging the surfaces.

Title: Method of producing polyvinyl alcohol fibre
IPC: D01F6/14
Filed: 1967-02-07
Abstract: 1,126,321. Wet spinning polyvinyl alcohol filaments. KURASHIKI RAYON K.K. 7 Feb., 1967 [8 Feb., 1966; 15 March, 1966 (2); 5 April, 1966], No. 5729/67. Heading B5B. Polyvinyl alcohol filaments are produced by wet spinning an aqueous solution of polyvinyl alcohol into a coagulating bath which is an aqueous solution of an inorganic salt and which is at a temperature above 55‹ C. and subjecting the filaments to cooling immediately after their being withdrawn from the bath, the cooling being effected at a temperature at least 30‹ C. below the temperature of the coagulating bath, and thereafter drawing the filaments in one or more stages at a draw ratio of not less than 4 : 1 and preferably not less than 6 : 1. The cooling may be effected by means of cold water and/or a cooled organic liquid, a cooled gas or cooling rolls. The concentration of the spinning solution may depend upon the average degree of polymerization of the polyvinyl alcohol used, the ranges of concentration being 20 to 50%, 15 to 45%, 10 to 40% and 8 to 35% corresponding to ranges of average D.P.s of 1000 to 1500, 1500 to 2000, 2000 to 3000 and 3000 to 5000 respectively. The organic cooling liquids which may be used include alcohols such as methanol and ethanol, acetone, esters, ethers and benzene. When a mixture of water and an organic liquid is used, the latter should be miscible with water. The salt present in the coagulating bath may be sodium, ammonium or zinc sulphate, sodium chloride or sodium carbonate. Two or more of these may be used conjointly. When sodium sulphate is used, the conjoint use therewith of potassium sulphate gives especially satisfactory results. In an example, a 15% aqueous solution of PVA of average DP 3000 is extruded into an aqueous solution of sodium sulphate at 80‹ C. and the filaments thereby formed are withdrawn from the coagulating bath, passed through water at 10‹ C., drawn by means of rolls at a draw ratio of 2 : 1 and further drawn at a draw ratio of 2 : 1 while wet with an aqueous solution of sodium sulphate at 60‹ C., the total draw ratio being 4 : 1. The filaments are then dried and drawn at a temperature of 235‹ C. and a draw ratio of 3 : 1, the overall draw ratio thus being 12 : 1. The filaments are thereafter heat set at 240‹ C. while being allowed to shrink 20%.
