Title: Process for the Continuous Preparation of Saturated and Unsaturated Secondary Fatty Amines.
IPC: C07C209/48
Filed: 1967-07-10
Abstract: 1,180,972. Production of secondary fatty amines. FARBWERKE HOECHST A.G. 10 July, 1967 [9 July, 1966], No. 31652/67. Heading C2C. Aliphatic saturated or unsaturated secondary fatty amines are prepared by hydrogenating a saturated or unsaturated fatty acid nitrile containing 8-22 C atoms and continuously passing the nitrile, at a temperature of 80- 250‹ C. and a pressure of 30-200 atmospheres, with hydrogen over a fixed-bed copper-chromium catalyst, the partial pressure of NH 3  in the hydrogen gas being maintained at 3-15% by volume. Preferred starting materials are the nitriles of caprylic, capric, lauric, myristic, palmitic, stearic, arachidic and behemic acids, or mixtures of two or more. Thus tallow fatty acid, coconut oil acid, oleic acid and soy bean oil acid may be used. The catalyst is preferably prepared by depositing a copper compound, a chromium compound and an alkali metal compound on a silica gel carrier and is reduced in a hydrogen flow at elevated temperature before use. Examples slow the hydrogenation, under various conditions, of the nitriles of tallow and soy bean fatty acids and stearic acid.
Patent GB-604096-A (GB)
Title: Radio direction finders
IPC: G01S1/02
Filed: 1945-11-23
Abstract: 604,096. Radio direction-finding. STANDARD TELEPHONES & CABLES, Ltd. Nov, 23, 1945, No. 31713. Convention date, Nov. 25, 1944. [Class 40 (vii)]. A radio direction-finder system comprises a number of fixed differently orientated directive antennµ with overlapping field patterns arranged to be successively coupled to a receiver, and an oscilloscope indicator with a synchronized sweep such that the beam is differently placed during reception by different antennµ, the receiver controlling a characteristic of the beam so that the amplitude of the signals received by the different antennµ will be indicated in different positions on the screen. As shown, four antennµ 1, 2, 3, 4, each backed by a reflector 5, 6, 7, 8, are connected successively to receiver 9 by switch 11 rotated by motor 12. An oscilloscope 17, whose sweep generator 18 is synchronized by unit 21 also driven by the motor has portions 22, 23, 24, 25, of the trace scanned during the respective connection, of antennµ 1, 2, 3, 4, to the receiver. The output of the receiver is fed to synchronous distributer 31 and as, in this example, signals from a distant transmitter can never be received on antennµ 1 and 3 or 2 and 4 at the same time, segments 28 and 30, and 27 and 29 are joined and then taken through attenuators 35 and 36 to a common amplifier 41 giving vertically deflecting signals to the oscilloscope. The reception of an incoming signal such as 16 by antennµ 1 and 2 will produce indications such as 44 and 45 respectively and from the position of these on the screen the quadrant in which the transmitter lies is known. The actual angle may be found from the adjustments of attenuators 35 and-36 which make the amplitude indications equal. Preferably the attenuators are differentially ganged and provided with a bearing scale 38. For communication purposes, or when tuning to a transmitter to be located, switch 46 may be closed to provide an omnidirectional aerial, motor 12 being preferably stopped at the same time by opening switch 14. Headphones 48 are connected to the receiver for the reception of messages and generator 18 may be designed to continue to produce a sweep in the absence of synchronizing signals so that signals may be observed. Intensity modulation of the oscilloscope, instead of vertical deflection may be used in the amplitude comparison.

Title: Improvements in the preparation of water-soluble chromium complexes
Inventor: VALLETTE PIERRE HENRI PAUL
IPC: C07F11/00
Filed: 1954-11-04
Abstract: The invention comprises a process for the preparation of a water-soluble complex salt of chromium and of a carboxylic acid containing more than three carbon atoms, by reacting a gaseous hydrogen halide, an alkali metal chromate (or bichromate), a carboxylic acid containing more than three carbon atoms or a substance yielding such an acid under the conditions of the reaction, and an alcohol or aldehyde, in the presence of an organic solvent, preferably an alcohol or a halogenated hydrocarbon.  Specified carboxylic acids include saturated and unsaturated aliphatic and isocyclic acids, e.g. fatty acids, resin acids, naphthenic acids, benzoic acid, naphthoic acids, crotonic and other methacrylic acids, and heterocyclic acids, e.g. furane carboxylic acid and indolyl acetic acid; as substances which can yield carboxylic acids under the conditions of the reaction are the corresponding aldehydes, alcohols and esters. The quantity of chromate should be sufficient to provide from 1-10 atoms of chromium per molecule of carboxylic acid.  The alcohol or aldehyde (included in the reaction mixture to reduce the chromium to the trivalent state) may be methyl alcohol, ethyl alcohol, paraldehyde, glucose, glycol monochlorhydrin, a polyhydric alcohol, higher alcohol or higher aldehyde.  In examples: (1) dry hydrogen chloride is passed into a refluxing mixture of stearic acid, sodium bichromate, ethyl alcohol and carbon tetrachloride until saturated, the solvent evaporated, and the residue taken up in boiling isopropyl alcohol and filtered to eliminate sodium chloride, giving a solution useful for waterproofing fabrics.  (2) As in (1), replacing stearic acid by palmitic acid, abietic acid, or cetyl palmitate.  (3) As in (1) omitting alcohol and replacing stearic acid by palmitate oil, Japan wax (tripalmitin) or octadecyl alcohol.  (4) Sodium bichromate in ethanol is saturated with hydrogen chloride, stearic or lauric acid added, and mixture kept at 70 DEG  C. until it is water-soluble, then diluted with alcohol and filtered.  Potassium bichromate gives similar results.

Abstract: 536,843. Hydrocarbons. POTTS, H. E. (Naamlooze Vennootschap Internationale Koolwaterstoffen Synthese Maatschappij (International Hydrocarbon Synthesis Co.).) Dec. 21, 1939, No. 32671. [Class 2 (iii)] In a process for the production of hydrocarbons with more than one carbon atom in the molecule by catalytic conversion of carbon monoxide in stages in series, with complete or partial removal of products after each stage, the throughput of the initial gas per cubic metre of catalyst is maintained the same in each stage, and is such as to produce the maximum amount of the hydrocarbons per volume of catalyst per hour. Throughputs of 200 to 600 cubic metres per cubic metre of catalyst per hour are used, and in order to maintain the same throughput in each stage, the volume of the reaction vessels in successive stages may be reduced in accordance with the decrease in the volume of the gases. Alternatively, reaction vessels of the same size may be used in each stage, fresh gas being added before each stage in order to maintain the throughput rate constant. The unconverted gases may be re-cycled. The usual catalysts are employed. Examples are given, in which the catalysts consist of cobalt, thorium or magnesium oxide, and diatomaceous earth.
