Title: Method of and apparatus for desiccating liquid or semi-solid materials
IPC: A23C1/08
Filed: 1941-05-09
Abstract: 562,470. Desiccating food products by freezing. STOKES MACHINE CO., F. J. May 9, 1941, No. 6054. Convention date, May 24, 1.940. [Classes 29 and 34 (ii)] [Also in Groups III, VI, XXVI and XXVIII] In the desiccation of sera and like biological materials or food products, e.g. milk, orange juice, soups, by freezing the material followed by withdrawal of moisture in vapour form from the frozen mass under high vacuum, the vapours are withdrawn without condensation or the use of desiccating agents by means of a pump and the water accumulating in the oil sealing liquid is removed continuously. When steam ejectors are employed as the evacuating medium two ejectors are employed in series and the moisture is removed from the vapours passing from the first to the second ejector. The liquid serum may be placed in bottles 3 or pans 4 m a chamber 1 cooled by circulating refrigerant through a coil 5. The chamber is exhausted through a pipe 1b connected to a rotary oil sealed pump 6a. The water vapours withdrawn become emulsified with the oil and are prevented from accumulating therein by circulating the oil through a centrifuge 7 in which the water is separated. Preliminary degassing of the material is effected in the initial stage by control of the air valve 8a. Alternatively two pumps 9, 11 may be used in series. The pump 9 is maintained at a temperature above the boiling point of water at the exhaust pressure of the pump and thus water eliminated is discharged as vapour into the condenser 10 where it is condensed by cooling coil 10a and removed from the vapours before they reach the pump 11. In a further modification the vapours are removed by a pair of steam ejectors in series and the water is removed by condensation in a condenser placed between the ejectors.

Title: Process and apparatus for the treatment of loose textile fibres

Filed: 1950-03-15
Abstract: <PICT:0677573/IV (c)/1> <PICT:0677573/IV (c)/2> <PICT:0677573/IV (c)/3> Textile material in the form of loose fibres is treated with a liquid in a continuous operation by forming a suspension of the fibres in a liquid and passing the liquid carrying the fibres in suspension through a totally-enclosed passage which is kept full of the treating liquid, the length of the passage and the rate of flow being such that the treatment is completed by the time the liquid carrying the suspended fibres leaves the passage, and separating the treated fibres from the liquid.  The process is particularly applicable for saponifying cellulose ester staple fibre, by cutting a bundle of continuous filaments into staple fibre, wetting with the saponifying agent, adding more saponifying liquid and treating as above.  An apparatus for this process shown in front elevational view in Fig. 1 and plan view in Fig. 3 comprises tow cans 12 from which tow 11 is passed over guide bars 13 and 14, over a tensioner 16, past feed rollers 24 into centrifugal cutters 28 which comprise casings 29 containing rapidly rotating discs 31 (Fig. 5) on shafts 32.  The tow enters the cutters 28 through apertures 36, passes by centrifugal force into the passageway 37 and is cut by cutting-blades 38.  The staple fibre so formed is sprayed with a saponification medium from conduits 39 and falls into a funnel 41 and through a horizontal enclosed passageway 42 in which saponification is effected.  The funnel 41 is located in a tank 43 kept supplied from a master storage tank.  After treatment the fibres emerge from tube 42 on to a wire mesh screen to filter off the bulk of the saponification medium before passing through squeeze rollers, after which they are washed with water free from saponification medium, and dried by centrifugal extractors, or by passing through rollers, and spun into yarn.

Abstract: 1294722 Shearing; stamping ROLLSROYCE Ltd 11 Feb 1970 6608/70 Headings B3Q and B3W In a method of and apparatus for shearing material, particularly sheet material formed into tubes, the material is supported against a shearing edge of a die and a compressive force is applied to a resilient medium, disposed in direct contact with the material to be sheared, in a direction parallel to the extent of the material surface to deform the resilient medium, and thus force the material against the shearing edge to shear it. As shown, a tube 28 to be sheared in mounted within a die ring 16 having an elastomeric support member 24 clamped thereto and a punch 30, comprising relatively movable members 32 and 34 with an elastomeric member 38 therebetween is lowered into the tube until the member 34 abuts an ejector pin 27. Further lowering of the press head 12 carrying the punch compresses the member 38 which is deformed radially outwardly forcing the tube wall against the die edge 26 where it is sheared. The punch is withdrawn and the two lengths of tube are ejected by the pin 27. The elastomeric member 24 which is deformed during shearing and thus controls the shape of the tube above the shear plane may be omitted if the material to be sheared is brittle. The edge 26 is preferably non-radiused and has an included angle of approximately 90 degrees. A forming operation may be performed by cooperation between the punch and suitably formed surfaces of the die holder 14 beneath the die 16.
