Title: New quinoline derivatives
Inventor: WILDE BERTRAND ERNEST
IPC: C07D215/06
Filed: 1953-10-14
Abstract: The invention comprises 2.2.4-trimethyl-decahydroquinoline and its salts, for example, the nitrite, carbonate and benzoate. 2.2.4-trimethyl-decahydroquinoline may be prepared by catalytically hydrogenating 2.2.4-trimethyl-1.2-dihydroquinoline and its salts by contacting 2.2.4-trimethyl-decahydroquinoline with the corresponding acid or other substance providing the acid radical.  The 2.2.4-trimethyl-decahydroquinoline may be used as a rubbery antioxidant, particularly in conjunction with benzyl cresols, and the salts, particularly the nitrite and carbonate are useful to reduce the tendency of metals to corrode.  In the examples: (a) 2.2.4-trimethyl-1.2-dihydroquinoline (obtained by passing acetone vapour into heated aniline in the presence of benzene sulphonic acid) is hydrogenated in the presence of a Raney nickel catalyst to give 2.2.4-trimethyl-decahydroquinoline; (b) 2.2.4-trimethyl-decahydroquinoline is dissolved in acetone and treated with nitrous fumes to give the nitrite of 2.2.4-trimethyl-decahydroquinoline; (c) the hydrochloride of 2.2.4-trimethyl-decahydroquinoline is obtained by treating it with hydrochloric acid; it is converted to the nitrite by treating it with sodium nitrite solution; (d) 2.2.4-trimethyl-decahydroquinoline, sodium nitrite and water are added to methanol to give the nitrite of 2.2.4-trimethyl-decahydroquinoline; (e) 2.2.4-trimethyl-decahydroquinoline is dissolved in a mixture of acetone and water and carbon dioxide is passed through to give the carbonate of 2.2.4-trimethyl-decahydroquinoline and (f) benzoic acid is dissolved in a mixture of petroleum ether and diethyl ether and 2.2.4-trimethyl-decahydroquinoline is added to give the benzoate. The 2.2.4-trimethyl-decahydroquinoline may be used as an antioxidant when mixed with a benzyl cresol which may be obtained by benzylating a commercial cresylic acid containing about 60 per cent of o-cresol.ALSO:2 . 2 . 4-Trimethyl-decahydroquinoline may be used alone or in conjunction with other antioxidants, as an antioxidant for rubber.  For example it may be mixed with a benzyl cresol, benzyl xylenols and other benzyl phenols, a mono-ether of a dihydric phenol, particularly a mono-ether of a commercial mixture of dihydric phenols containing a preponderance of catechols, or a trialkyl phenol, especially 2 . 4-dimethyl-6-octyl phenol, 2 . 6-dimethyl-4-octyl phenol and 2 . 6-dibutyl-4-methyl phenol. These antioxidants may be used with both natural and synthetic rubber.

Title: Process for the artificial production of fats
IPC: C11B1/00
Filed: 1937-10-18
Abstract: 509,755. Food preparations. BRANDT, K. Oct. 18, 1937, No. 28254. Convention date, Oct. 17, 1936. [Class 49] [Also in Group IV] Synthetic fats are produced by mixing carbohydrates with fresh animal albuminous pulp, the mixture being kept at or near the neutral point, and separating the fat formed. Putrefaction may be prevented by adding salts such as sodium, potassium, calcium or magnesium chlorides, preferably a mixture in which sodium chloride predominates, and boric acid or its salts may also be added. Basic substances or buffers may be added to maintain neutrality. When the quantity of carbohydrate is a multiple of the quantity of albumen, ample air supply is favourable. The reaction temperature may be below 60‹ C., such as 30-40‹ C., the time being 4-5 days for this range. The fat produced may be separated by pressing, solvents, or by emulsification in water and centrifuging. The carbohydrates employed may be cane sugar, milk sugar, glucose, and, when the albuminous material contains enzymes, starch. The residue left after the extraction of the fat is dried and forms a " strengthening food ". Suitable albuminous material is fish waste. In an example, 100 parts of herring pulp is mixed with 15 parts of a salt mixture containing 96 per cent sodium chloride and 2 per cent each of potassium and calcium chlorides, and 5 parts glucose and 10 parts milk sugar are added, the mixture being stirred at 40‹ C. for two days ; then glucose and milk sugar are added and the treatment continued for another two days, and finally a third addition of the sugars is made, the treatment being completed in a further two days.

Title: Stabilising or anti-rolling equipment, particularly for ships
IPC: B63B39/02
Filed: 1948-11-02
Abstract: 689,682. Automatic stabilizing systems. POLLOPAS PATENTS, Ltd. (Montrose-Oster, L. E. W.). Nov. 1, 1949 [Nov. 2, 1948], No. 28388/48. Class 38 (iv). [Also in Groups XXXIII and XXXVII] Relates to a stabilizing equipment for ships and the like of the type employing a movable weight. At the bottom of the hold of the ship are provided rails 3 and racks 8 mounted transversely to the direction of travel and position as far as possible below the centre of gravity. These parts may be installed on a surface the curvature of which allows truck 1 to be displaced on a nearly horizontal plane. The truck carries its electric traction motors and one or more motor-generator or converter groups for supplying the motors. Fixed to driving-wheels 2 are toothed wheels 4 intercoupled by pinions 5 mounted on a common shaft 6. The shaft is driven by pinion 51 which meshes with a cage 7 of a differential having toothed wheel 4<SP>1</SP> gearing with rack 8. Directcurrent traction motors 11, 11<SP>1</SP> rotate in opposite directions and drive the free shafts of the differential, so that inequality of the speeds of the motors causes movement of the truck. The motors are supplied from a Ward-Leonard Ilgner set comprising fly-wheel 12, generator 13, A.C. motor 14 fed from the power plant of the ship, and an exciter 15. The truck also carries regulating apparatus of the type described in Specification 689,681, [Group XXXIII]. The truck will move along the rails from one side to the other under the control of the regulating apparatus responsive to the factors influencing the rolling of the ship. It is arranged that the maximum stabilizing couple is obtained when the truck is still spaced from the end of its travel. If the truck over-runs it will engage buffers and remain stationary until the control responds to move the truck towards the opposite side. The truck is started by increasing the field excitation of one motor and decreasing that of the other, reversal being also effected through field control. A sudden change of the instantaneous value of the turning moment upon the ship due to the wave action causes a rapid alteration of the rate of acceleration of the truck and this produces a reactive force upon the rails which is of short duration and acts in a direction to counteract such sudden change. The stabilizing system may be applied to floating vessels in general, and to parts of vessels such as gun mountings.
