Title: Improvements in or relating to stabilising apparatus
Inventor: IRVINE JOHN ANDERSON
IPC: G05D1/08
Filed: 1964-02-14
Abstract: 1,037,137. Automatic position stabilization. FINDLAY, IRVINE Ltd. May 14,1965 [Feb.14, 1964; Oct. 27,1964], No.'s 6395/64 and 43810/64, Heading G3R. In a system in which a servo-mechanism maintains a body in a desired attitude, deviations of the body are detected by variations of liquid level in a U-tube forming a capacity in an A.C. circuit controlling the servo-mechanism. As applied to ship roll stabilization, mercury in a glass U-tube, having a restriction to provide damping, forms one electrode of a differential capacitor with the other electrodes outside the tube. This differential capacity is included in an A.C. bridge circuit the output of which, being dependent on the angle of roll, controls, through a transistor amplifier, a solenoid-operated hydraulic actuator for stabilizing fins on the ship. Signals dependent on rate of roll and roll acceleration are obtained by differentiation and added to the angle of roll signal. In one modification a pair of U-tubes are used with opposite capacitors connected in parallel and one U-tube being maintained in a datum position by a gyro to eliminate signals due to transverse acceleration. In another modification both electrodes are outside the U-tube and the liquid within forms the dielectric. Use of U-tubes with only one capacitor limb, manually adjustable capacitors to provide temperature compensation or correct list, and control of water flow between tanks on each side of the ship instead of controlling fins, is referred to.

Title: Improvements in and relating to the obtention of coal extracts
IPC: C10G1/04
Filed: 1937-03-11
Abstract: In the extraction of coal with solvents under elevated temperature and pressures, the coal is formed into a mash with hydrogenated oils, tar oils or mixtures thereof, and the mash treated at 425 to 435 DEG C., with a throughput of 1 Kg. mash per litre of reaction space per hour, or at 440 to 450 DEG  C. with a throughput of above 1 up to 2 Kg. of mash, whereby coking is avoided and filterable extracts are made.  A short initial heating of the mash at temperatures somewhat above these temperatures may be used.  Mineral coal, brown coal and peat are treated, the higher extraction temperature being used for poor coals. Example: mineral coal is formed into a mash with 1 1/2 times its weight of a solvent mixture containing tetrahydronaphthalene and cresol.  The mash is passed through a heating chamber at 430 DEG  C. and under 100 atmos. pressure at 1 Kg. of mash throughput.  The tetrahydronaphthalene loses a part of its hydrogen to the extract.  The crude extract is cooled to 200 DEG  C., is freed from ash in a centrifuge and then freed from solvent by distillation. A fusible pitch-like extract is obtained which is worked up into a fuel oil or motor fuels, for example by splitting hydrogenation.
