Title: Improvements in or relating to magnetic cores or other magnetic bodies and the manufacture thereof
IPC: H01F1/24
Filed: 1924-11-15
Abstract: 247,301. Callender's Cable & Construction Co. Ltd., and Watson, J. F. Nov. 15, 1924. Transformers. - Magnetic bodies comprising iron particles in a binding material, and more especially cores for wireless and other transformers not subjected to excessive heat, are made by intimately mixing the particles and binder at a temperature at which the material is plastic but not molten, and allowing the material to cool and set. The mixing is preferably done in a masticator and the mixture moulded whilst plastic, as for example within or around the winding of a transformer. Suitable binding materials are high melting point gums (such as manilla or Kauri), bitumens (free from sulphur), resins or lac (without spirit). In one example levigated iron passing a 1.50 mesh sieve, and seed lac, in the proportions of 90 per cent iron by weight and 10 per cent of seed lac, are mixed at about 80- 85‹ C. In another example coal tar pitch previously heated, say to 150‹ C., to remove volatile solvents, may be used in the same proportions and mixed at a temperature of 85-90‹ C. Reference has been directed by the Comptroller to Specification 25638/04.

Title: Process and apparatus for the separation of materials of different specific gravity and sizes
IPC: B03B5/62
Filed: 1947-10-11
Abstract: 653,397. Washing granular &c. materials. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Oct. 11, 1947, No. 27343. [Class 82(ii)] A process for the separation of materials of different specific gravity and sizes in which the material is delivered into a substantially conical vessel containing an unstable suspension of fine heavy particles, the particles in the separation zone being kept in suspension by upward currents in the liquid, in which the floats from said zone are overflowed from the top of the vessel together with some liquid and the sinks discharged through an apex aperture, and in which an upward current of liquid at variable velocity is directed through said apex aperture into the suspension to lessen irregularity in the specific gravity of the suspension in the suspension zone, is characterized in that the velocity of the stream of liquid is varied in dependancy upon variations in the specific gravity of the suspension in the separation zone. In one form the sink materials discharge into a discharge chamber having an outlet for the materials and an inlet for the stream of liquid, the velocity of the upward current being adjusted by varying the difference between the outlet and inlet to the chamber. The amount of inlet liquid may be kept constant and the size of the outlet varied or the separator may be connected to the discharge chamber by an iris valve the diameter of the opening of which may be varied; preferably, however, the outlet from the chamber is kept constant and the inlet to the chamber varied by means of an iris valve. An apparatus for carrying out the process comprises a conical portion 1 surmounted by a cylindrical portion 2 provided with a weir 3 and a launder 4. The material to be separated is fed from a shoot 6 to another shoot 5 and the suspension particles are kept in suspension by an upward current throughout the separator. from nozzles not shown, and bv a rotatable shaft 7 carrying agitator blades 8. A discharge tank 11 connects to the apex aperture 10 and has an inlet from pipe 12 and an outlet at 13 to a cyclonic discharge device 15 in which the liquid and sink materials enter tangentially at 14 and are discharged through an axial outlet 16. The cyclonic discharge apparatus is described in Specification 653,394, [Group XXIX]. Air is admitted by a valve 20 to a dip tube 18 which is placed in the separation zone and from which air bubbles. The pressure in the pipe 19, and therefore also pipe 21, depends on the specific gravity of the suspension at the separation zone and any change of pressure affects a Foxboro instrument 22. This instrument amplifies the change and the increased pressure change actuates the membrane of a pressure reducing valve 23 in the air supply pipe 25 to an iris valve 27. The iris valve 27, comprising a cylindrical tube the diameter of which can be varied by altering the pressure in the tube, is in the liquid supply pipe 12 so that change of pressure in the pipe 18 alters the amount of liquid flowing into the discharge chamber.
