Title: Improvements in or relating to the drying of fish
IPC: A23B4/10
Filed: 1944-03-14
Abstract: In a process of drying white fish comprising cooking at low steam pressure mincing and drying in a current of hot air, an edible fat, e.g., deodorized cocoa-butter or cod liver oil is added between the cooking and drying stages.  The fat (20-30 per cent. by weight on a dry basis) in liquid form may be mixed with the cooked fish by hand before, during or after the mincing or in a mixer before mincing or by adding it as the fish goes into the mincer.  The product is then dried to about 10-12 per cent. water content and compressed into blocks.  Alternatively fat may be poured onto the fish from which water has been pressed and the product broken up and dried.  The compressed block can be stored in a hermetic can, the space in the can being filled with liquid fat before sealing.

Title: Improvements relating to cotton bale opening machines
IPC: D01G7/00
Filed: 1945-02-26
Abstract: 590,354. Cotton bale opening machines. FROST, W. Feb. 26, 1945, No. 4780. [Class 120 (i)] In a cotton bale opening machine employing several endless band conveyers, bales are passed from one conveyer to another over one or more revolving toothed cylinders, the teeth of which project slightly above the level of the bottoms of the bales, so that a thickness of cotton is beaten therefrom. As shown bales are fed backwards and forwards between lattice conveyers a, b along supporting bars c through which the teeth e of a high speed revolving toothed cylinder d project slightly. Cotton beaten off the bottom of each bale is detached from the cylinder teeth by fixed teeth f, g and' drops into a cotton receiving chamber h whence it is withrawn by suction through outlet i. Drive is supplied by reversible motor j. Mixing may be achieved by dealing simultaneously with several bales of different qualities, reversal of the drive being arranged to operate after all the bales have passed the toothed cylinders. The lattice conveyers may alternatively be arranged in a closed. path in conjunction with two or more toothed rollers, drive being continuous in one direction.

Title: Improvements in or relating to the extraction of non-fatty materials from animal or vegetable materials
Inventor: CHAYEN ISRAEL HARRIS
IPC: C11B1/00
Filed: 1953-02-20
Abstract: Animal or vegetable material is subjected to intense impacts delivered through the medium of a suitable liquid to disrupt its structure under such conditions that a substantial proportion of the solid residues of the material is not reduced to colloidal or near-colloidal size, and non-fatty substances are recovered from the mixture.  The process is applicable to the extraction of organ extracts from animal organs (e.g. Vitamin B12 from livers), glandular extracts from glands (e.g. insulin from pancreas), essential oils and flavourings such as lemon essence and vanilla. If the desired substance is water-soluble, water may be used as a liquid and the desired substance recovered from solution. Alternatively the liquid may be one in which the desired substance is insoluble but in which at least part of the residue is soluble.  Organic liquids which may be used include hexane and petroleum fractions, trichlorethylene, carbon tetrachloride, alcohols, glycols and ketones.  The extraction may be carried out in a hammer mill using a volume of liquid 1 to 30 times that of the material to be extracted.  The examples describe the extraction of Vitamin B12 from ox liver and vanilla extract from vanilla pods and beans.  Specifications 714,671, 722,311, [both in Group III], and 742,537 are referred to.ALSO:Animal or vegetable material is subjected to intense impacts delivered through the medium of a suitable liquid to disrupt its structure under such conditions that a substantial proportion of the solid residues of the material is not reduced to colloidal or near-colloidal size, and non-fatty substances are recovered from the mixture.

Title: Improvements in or relating to the production of artificial filaments and like materials
IPC: D01F2/30
Filed: 1935-02-15
Abstract: <PICT:0448570/IV/1> A process for the production of artificial filaments or like materials with a flat or ribbon like cross-section and of dull lustre by the dry or evaporative method comprises extruding a solution of cellulose acetate or other organic derivative of cellulose through spinning orifices and directing a current of moist steam on to the filaments immediately after the extrusion thereof.  Apparatus for carrying out the invention comprises a nozzle so disposed in the cell that steam issuing therefrom is directed across the filaments near the face of the spinning jet preferably in the form of a flat stream.  The nozzle preferably applies the steam at a point less than 2", e.g. \ba1/2\be" from the face of the spinning jet in a direction slightly inclined to the direction of extrusion.  The filaments formed may be collected as threads of continuous filaments, or may be cut to staple fibre to be spun to form yarn.  The steam employed preferably contains just enough moisture to exert a precipitating action on the filaments as they issue from the jet.  The usual current of evaporative medium may be employed wholly or in part in addition to the steam.  Suitable apparatus comprises a spinning cell 5 with a supply pipe 6 for spinning solution, filter candle 7 and spinning jet 8.  A nozzle 15 introduces steam from the header 16 and directs it down the spinning cell to pass as a thin flat stream across the filaments at an angle. A valve 17 controls the flow of the steam.  If desired, two nozzles may be fitted, one on each side of the bundle of filaments.  In a further modification, a hollow annular member which completely surrounds the filaments is employed to supply the steam.  The steam supplying means may be adjustable with respect to the spinning jet. The filaments are spun on a cap-spinning device outside the cell which may have means for allowing the entry and drawing off of air.
