Title: Improvements in or relating to the treatment of whale gluewater
IPC: C09H3/02
Filed: 1950-08-11
Abstract: <PICT:0687513/III/1> Whale gluewater is treated to recover suspended solids, suspended oil and a processed stable gluewater of value as an animal food, by adding thereto an acidic material in amount sufficient to reduce the pH of the gluewater to within the range 4 to 5 while maintaining the temperature of the gluewater above 180 DEG F. but below boiling, holding the treated gluewater static for a period of at least 15 minutes, and thereafter separating the undissolved solids and the liberated oil from the gluewater.  The pH range is preferably 4 to 4.5, such as 4.2.  The acidic material is preferably sulphuric acid, but may be aluminium sulphate, any of the alums, ferric chloride or tannic acid.  The gluewater from the time of its production through the time of pH adjustment is preferably kept at a temperature above 180 DEG  F. and such temperature is preferably continued during the separation of solids and oil.  The holding period is preferably at least 30 minutes.  The final treated gluewater is subjected to vacuum evaporation to produce a concentrated product, such as a product having a soluble solid content of between 50 and 60 per cent by weight.  The separations may be made by any suitable separation devices, mainly by various types of centrifuges, particularly a continuous sludge-discharge, horizontal type centrifuge for the removal of the solids and a continuous, three-phase nozzle-discharge type centrifuge for the removal of the oil.  In a suitable plant, the hot gluewater, obtained from whale parts by usual methods, is pumped through conduit 11 to one of a number of acidulation tanks 10 to which the required amount of acidic material is fed continuously into admixture therewith through a conduit 15 and drip tank 16.  After the tank is filled and the pH adjusted the tank is kept static at at least 180 DEG F. for the specified time.  The hot mixture from the tank 10 is then passed into a continuous sludge-discharge, horizontal-type centrifuge 20 from which the solids are discharged into a cart 23 and the liquid component into a tank 24.  From the latter the liquid is pumped through a heater 27 into a feed tank 28 supplying a centrifuge 30 suitable for separating the oil from the aqueous gluewater, such as described above.  The heater 27 preferably raises the temperature of the gluewater above 200 DEG F., e.g. 210 DEG F. The stabilized gluewater discharged from the centrifuge 30 is pumped into a storage tank 34, from which it may be supplied to a vacuum evaporator 35. The concentrated product is stored in a tank 43.  In a modified plant, the oil is removed prior to the solids by interchanging the positions of the centrifuges 20 and 30 together with their appurtenances.  Specification 543,508, [Group II], is referred to.

Filed: 1952-08-14
Abstract: 711,553. Surgical swabs. BARNHARDT MANUFACTURING CO. Aug. 14, 1952, No. 20457/52. Class 81(2) [Also in Group XXV] In a machine for producing continuous lengths of absorbent material suitable for cutting to form dental rolls, a cylindrical body of fibre is bound with threads, some of which are then rendered adhesive. Continuous lengths of cotton fibre 10a, 10b are drawn from supply drums 11a, 11b and shaped into a circular cross-section by a member 16, after which the core, so formed, passes through a braiding machine supplying a number of threads, of which a proportion are of cellulose acetate. The composite cord is drawn forward by a pulley 29 and passed to a chamber 32 wherein nozzles 34 spray it with acetone to soften the cellulose acetate to cause adhesion of the braiding to the absorbent core. It continues through a solvent recovery chamber 35 and drying chamber 36 to a winding mechanism 37. In the arrangement described, the braiding machine applies eight strands each consisting of two threads, one of cotton and the other cellulose acetate. Threads of alternative materials capable of being rendered adhesive by a solvent or heating may be used, and, instead of braiding, two oppositely wound layers of thread may be applied. A slightly looser packing of the fibrous material may be achieved by arranging a central rod-like member to occupy the centre of the fibre core until after the braiding has been applied so that as the composite cord is drawn off it a central hole is left into which. the fibre can expand.
