Patent GB-365530-A (GB)
Title: A method of preserving fish
IPC: A23B4/08
Filed: 1930-09-15
Abstract: Fish is preserved without freezing by slow percolation with fresh or sea water which has been saturated with air and is at a temperature slightly above 0 DEG  C. but may be slightly below this temperature where sea water is used.  The water may be supplied continuously or intermittently to the fish.  In one form, sea water before supplying it to the fish is pumped through a filter into a tank in which it is aerated and cooled, or the water may be cooled in one tank and aerated in another by forcing air in below water-level through small inlets such as through porous bricks. Aeration may also be effected by atomizing the water in the trawler hold, bin, &c., containing the fish so as to create a mist which condenses on and trickles through the fish.  The fish may be cooled before being treated.

Abstract: 743,335. Slub yarn producing mechanism. HAYESHAW, Ltd. Oct. 22, 1953 [Nov. 1, 1952; Feb. 6, 1953], Nos. 27526/52 and 3342/53. Classes 120 (2) and 120 (3). An irregularly operated control motion for arresting the movement of either the feed or delivery rollers of a spinning frame to produce slub yarns has a control member rotatable about a horizontal axis and provided with pockets from one to another of which a tumbler falls for random actuation of roller arresting mechanism. The tumbler is preferably spherical and more than one may be employed if desired. The pockets 6 are spaced round the internal periphery of the control member 1 and as the member rotates the tumbler falls across the space between the pockets 6 being prevented from falling out by a plate 33 which is cut away at 35 to enable an arm 7 to overlie the pockets 6 so that if the tumbler is held in a pocket passing beneath the arm 7 the latter is raised to operate a switch 11. In order to increase the random nature of tumbler movements, various deflector members may be mounted on a shaft 27, some of the pockets 6 may be of greater depth than others and small idler tumblers may be introduced. According to the Provisional Specifications the tumblers may have flat faces and the second Provisional Specification states that a counter or pen recorder may be associated with the control motion to record the number, frequency and/or duration and spacing of the abnormal roller movements.

Title: Improvements in or relating to the treatment of materials made of or containing cellulose esters or ethers
IPC: D06M11/64
Filed: 1928-09-29
Abstract: 324,662. Dreyfus, H. Sept. 29, 1928. Yarns, treating with liquids. - Filaments, threads, yarns, and other textile products made of or containing cellulose acetate or other organic esters of cellulose, for example, cellulose formate, propionate or butyrate, or cellulose ethers, for instance methyl, ethyl or benzyl cellulose, are treated, subsequent to or continuously with their production, with concentrated mineral acids whilst they are under tension. Suitable acids comprise, for example, sulphuric acid of specific gravity 1.15-1.4, hydrochloric acid of specific gravity 1.1-1.2, nitric acid of specific gravity 1.12-1.28 and phosphoric acid of specific gravity 1.3-1.5. Materials treated in this manner possess increased tensile strength. The materials may be stretched either during or immediately after the acid treatment. The acids are preferably finally removed, for example, by washing, but the materials may be given a short run in air before removal of the acids. In examples, cellulose acetate filaments or threads are passed from a bobbin or package direct from a dry or wet spinning apparatus at a speed of 20-30 metres per minute, through a bath comtaining sulphuric acid of 1.3 specific gravity and are carried out of the bath over a feed roller, which maintains a tension therein or runs at a sufficient speed to stretch the materials, into a bath of dilute ammonia and are finally wound or twisted and wound; a ribbon of cellulose acetate is passed at a speed of 4 metres per minute through a bath containing sulphuric acid of 1.22 specific gravity whilst maintaining it under sufficient tension to prevent shrinkage and then into a bath of dilute ammonia and is finally reeled whilst running in water; cellulose acetate filaments or threads are passed from a bobbin or package or direct from a dry or wet spinning plant at a speed of 20-30 metres per minute round a feed roller into nitric acid of specific gravity 1.22 and are carried out of the bath over a second feed roller running at the same speed so that no shrinkage is allowed to take place and the materials are then washed off and reeled; cellulose acetate filaments or threads are passed round a feed roller rotating at a peripheral speed of 1 metre per minute, thence into a bath containing nitric acid of specific gravity 1.28 and are carried cut of the bath over a feed roller rotating at a peripheral speed of 1.1 metre per minute. In order to moderate or render more uniform the action of the mineral acids, substances such as glycerine, glucose or other sugars, alcohols, acetic acid or its homologues, acetone or its homologues, or sulphonated oils, may be added thereto. The Provisional Specification also refers, for example, to the employment of sulphuric acid of 1.4-1.84 specific gravity; nitric acid of 1.28-1.42 specific gravity and phosphoric acid of specific gravity 1.5-1.8. Specification 323,790 is referred to.
