Title: Improvements in the separation of oils from mixtures of the same with solid substances
IPC: C10G1/04
Filed: 1928-02-22
Abstract: 312,383. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 22, 1928. Mineral and tar oils, extracting.-Oils are extracted from shales, coals, residues obtained in destructive-hydrogenation, or other mixtures with solid substances, by treating hot with organic solvents having great solvent power for the oil when hot but little when cold, freeing the solution from undissolved residue, and then separating the oil from the extract by cooling and centrifuging or other mechanical means. The suitabilitv of a solvent is ascertained bv a preliminary test tube experiment. The process may be continuous, and may be conducted under pressure. When coals, shales, and the like are extracted alkali sulphides or other substances accelerating the extraction or the decomposition of the coals &c. may be present. Suitable apparatus comprises an extractor b through which the raw material falls against ascending heavy benzine. The extract passes to a cooler e and a centrifuge f. The separated oil passes off through a pipe k. The solvent flows through a pipe l and a heater h, raising the temperature to 100-120‹ C., to a cellular or plain filter i in which it washes the residues discharged either continuously or intermittently from the extractor; it is then forced by a pump m to the extractor for re-use. The residues may be treated again or by another process, e.g. with light benzine. In a modified apparatus the coal &c. mav be conveyed upwards against descending solvent. In an example, oil shale is extracted at 340‹ C. and 200 atmospheres by an oil boiling up to 280‹ C. and of S.G., 0.810 obtained bv the destructive hydrogenation of lignite, producer tar. The extract is freed from the solid residue at 125‹ C. and atmospheric pressure, and is then cooled to 0‹ C. when layers of oil and solvent form which are separated by centrifuging or syphoning. The solvent retains only 10 per cent of the extracted oil.

Abstract: 433,729. Fluid - actuated valves. MOUSLEY, A., c/o Winn & Co., Granville Street, Birmingham, and CRITTALL & CO., Ltd., R., 43, Bloomsbury Square, London. Feb. 22, 1934, No. 5829. [Class 135] Valves controlled by pilot or relay valves.-In a valve of the type in which fluid pressure maintains the valve a<1> in one position, i.e. either opened or closed, and the valve is moved to the other position by opening an electromagneticallyoperated pilot valve so as to cause fluid pressure to be admitted to a chamber a<6> beneath a piston a4 fixed to the valve stem a<2>, the chamber a<6> is in communication with the outlet side of the valve a<1> by a narrow passage a<3> in the stem a<2> and a small opening a' from the passage as to the outlet side, so that the fluid can only escape gradually from the chamber a<6> and thus the valve a<1> moves slowly back to its initial position when the pilot valve is closed. In one form, the passage a<3> extends through the whole length of the stem a<2> and is closed on the inlet side by a pilot valve b<2>. Energization of an electromagnet B causes the valve b<2> to be raised so that pressure fluid flows through the passage a<3> to the chamber a<6> thus causing the main valve a<1> to be raised. The valve b<2> may be raised by spring action and closed by the energizing of the magnet B. In a modification, the passage a<3> does not extend to the inlet side of the valve a<1> but a pipe connects the inlet side to the chamber a<6> and flow therein is controlled by an electromagnetically-operated pilot valve.
