Title: Improvements relating to the continuous extraction of substances from solid matter by means of a solvent
IPC: C11B1/10
Filed: 1946-04-16
Abstract: Oil is extracted from kernels in apparatus suitable for continuous extraction (counter-current principle) comprising an endless open-work conveyer upon which the disintegrated material is fed and beneath which are tanks in which the liquid passing through the material collects, the tanks being connected by overflow means so that liquid extracts of progressively increasing concentration overflow continuously from tank to tank from the discharge to the feed ends of the conveyer, such extracts being produced by recirculation of liquid from and back to each tank through the material of the conveyer.  As shown, the ground kernels are <PICT:0616825/III/1> fed from a hopper 2 on to a conveyer 5.  A pump 7 feeds fresh solvent upon the kernels, which have already been progressively exhausted by treatment with liquid extracts of decreasing oil content, the solvent falling from the sprinklers 16, through the bed 4 and into a tank 23.  The liquid extract so formed is taken up by the pump 8 and discharged through the sprinklers 17 upon the kernels lying above the tank 23, while the liquid extract collecting in tank 23 finally overflows through the pipe 30 into the neighbouring tank 24.  In like manner, the liquid extracts in tanks 24-29 are passed through the kernels directly above these tanks by means of pumps 9-13 and sprinklers 18-22 respectively. The richest extract overflows from tank 29 into a storage tank 31 from which it passes to a solvent recovery apparatus.  Before the exhausted and drained-off kernels are unloaded at 38 into a hopper 33, solvent drippings are collected in a tank 32 and may overflow into the adjacent tank 23 or be introduced directly into the liquid extract circuit as at 40.  After unloading, the conveyer is washed with filtered liquid extract from tank 31, the washings being collected in a tank 36 from which it is passed through fresh kernels at 37.

Filed: 1932-04-23
Abstract: 400,277. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and ROBINSON, F. E., Old Heath House, Colchester, Essex. April 23, 1932, No. 11735. [Class 37.] An inductance coil having a negligible external magnetic field is made by filling a wound coil with a mixture of latex and dust of magnetic material and then solidifying the latex. A coil 1 is wound on a straight former 2, Fig. 1, in a number of layers, each layer being brushed over with latex. The coil is then dipped in latex and wholly or partly vulcanized. The former 2 is then removed and the coil again dipped in latex to give a coating inside the coil. The coil 1 is then bent round into toroidal shape but with a space left between the ends, as shown in Fig. 2, and is placed in a deep glass container in which a mixture of latex and iron dust is poured. The iron dust gradually settles and fills up the coil, a current being passed through the coil so that the particles of iron take up their correct magnetic positions. Surplus latex is then poured off and the container and coil are placed in an oven to vulcanize the coil. In an example a mixture of 80 parts by weight of iron dust to 20 parts of latex is employed. In an alternative method the coil is filled with a paste of iron dust and latex before being bent into toroidal form. An ordinary flat wave wound coil may be employed instead of a toroidal coil. According to the Provisional Specification, binding material other than latex may be employed.
