Title: Manufacture of aminoalkoxy-derivatives of aryl-quinolines
Filed: 1930-05-16
Abstract: Aminoalkoxy derivatives of arylquinolines are prepared by (1) interaction of an oxyarylquinoline with an aminoalkylating agent, (2) interaction of a halogen-arylquinoline with an aminoalcohol, (3) treating a halogenalkoxyarylquinoline with an amine, (4) converting an aminoalkoxy aromatic compound by ring-closure into the corresponding arylquinoline compound.  An acid-binding agent is preferably employed in processes (1), (2) and (3).  The products, which form water-soluble salts, are useful therapeutically.  Examples are given of the preparation of (1) 2-phenyl-7-diethylaminoethoxy-quinoline by reacting 2-phenyl-7-oxyquinoline with chlorethyldiethylamine, or 2-phenyl-7-bromethoxy-quinoline with diethylamine; (2) 2-diethylamino-ethoxy-3-phenylquinoline by treating 2-chloro-3-phenylquinoline with diethylaminoethanol; (3) 2-(p-diethylaminoethoxyphenyl)-quinoline by interaction of 2-(p-oxyphenyl)-quinoline and chlorethyl-diethylamine; (4) 2-phenyl-6-piperidylethoxy-4-quinolinecarboxylic acid by heating p-piperidyl-ethoxyaniline (obtained by saponifying the piperidylethylether of p-acetylaminophenol) with benzaldehyde and pyroracemic acid.  In a similar manner the following compounds can be made: 2-phenyl-6-diethylaminoethoxy-quinoline, 4-phenyl-7-diethylaminoethoxy-quinaldine, 4-phenyl-7-di-cyclohexylaminoethoxy-quinaldine and 2 : 4-di-(diethylaminoethoxy)-3-phenylquinoline. 2-Phenyl-7-bromethoxyquinoline is obtained by treating 2-phenyl-7-oxyquinoline with ethylene bromide.  2 - Chloro- and 2 : 4 - dichloro - 3 - phenylquinoline result when 3-phenylcarbostyril and 2 : 4-dioxy-3-phenylquinoline respectively are heated with phosphorus oxychloride.  Dicyclohexylaminoethanol is prepared by reaction between dicyclohexylamine and glycol chlorhydrin. Chlorethyldicyclohexylamine is obtained by heating dicyclohexylaminoethanol with thionyl chloride.

Title: Improvements in or relating to the preparation of aqueous emulsions
IPC: C09K23/00
Filed: 1938-05-20
Abstract: 515,021. Food: medicines. HILTNER, P. P. May 20, 1938, No. 15157. Convention date, Oct. 11, 1937. [Classes 49 and 81 (i)] [Also in Groups III and IV] Stable aqueous emulsions are prepared with the aid of albumen obtained from muscle fibres of animal origin, especially from aquatic animals. The albumen is preferably prepared from the flesh of fresh marine animals and is partly or wholly freed from more easily soluble and fatty constituents. A preliminary emulsion is preferably first formed by swelling the albumen, the remaining liquid being then added. In an example, comminuted muscle flesh of cod is treated at 65C. with water adjusted to pH of about 4 with citric acid to dissolve out unwanted constituents and the albuminous substance is separated, e.g., by centrifuging, washed, dried at low temperature and ground. Further fatty constituents may be removed by treatment with solvents, e.g., alcohol, benzene, benzine, carbon tetrachloride &c. The product may be further treated with alkalies. Further examples describe the use of the albumen for the preparation of mayonnaise, salves, butter cream, bakery products, cod liver oil emulsion and emulsions for textile and leather treatment.

Title: Cartridges and the like moulded bodies for the generation of pure oxygen for respiratory purposes
IPC: A62B21/00
Filed: 1936-06-05
Abstract: In the generation of oxygen by the decomposition of substances such as chlorates and perchlorates, the gases are passed directly after their formation and while still warm over catalysts not forming part of the oxygengenerating mixture and which convert any carbon monoxide present into carbon dioxide.  Suitable catalysts are metallic oxides, e.g. manganese oxide which may be mixed, if desired, with copper oxide.  When using the oxygen-generating mixture in the form of a cartridge or similar moulded body, the latter is surrounded by slag wool, glass wool, pumice powder &c., impregnated with the above catalysts and also with chemicals which react with the carbon dioxide formed. Suitable chemicals are the oxides and hydroxides of the alkali and alkaline earth metals, or preferably the peroxides of these metals, which generate oxygen by reaction with carbon dioxide. Specification 451,170 is referred to.

The sheet is placed between the plates y, z of a folder frame pivoted at x and the first row of holes are threaded over upstanding fingers 1 with springs and a former, Fig. 17, being then placed on top. The frame then makes one sweep through 180‹ by the operation of the toothed quadrant 20 and gearing so as to wrap the sheet round three sides of the former and align the next row of sheet holes with the ends of the fingers 1. The slide e carrying the fingers 1 is then reciprocated a short distance to the right to pullout enough lead sheet from between the folder plates to allow another former to be placed over the fingers and press down the folds, so that on the next sweep of the folder from left to right another piece of the lead sheet is wrapped round three sides of the second former and so on. The slide e carrying the fingers e &c. is reciprocated from cam the stroke of the slide being capable of variation to determine the length of lead pulled out at each stroke and so determine the depth of the folds. The sweep of the folder frame about its axis x is obtained from the camoperated bell-crank lever 22 of the toothed quadrant 20. The machine may be driven by a handle 28 or by power. The sweep frame is counterbalanced by an adjustable weight 34. Specification 353,154 also is referred to.

Abstract: 938,972. Transmission and distribution networks. GENERAL ELECTRIC CO. Ltd. April 12, 1962 [May 3, 1961], No. 16038/61. Class 38 (4). An impedance link between two alternating current networks 1, 2 comprises an inductor or transductor 3 and a capacitor 4 which are tuned to the network frequency so as to have a low impedance. When a fault condition arises such as a short circuit in one of the networks the voltage across the capacitor 4 increases whereupon the spark gap 8 breaks down to energize a coil 6 which closes contact 5 to short circuit the capacitor 4, the link impedance then being that of the inductor 3 only. During fault conditions the difference in voltage between the networks energizes a relay 9 to open contacts 10 so that the coil 7 associated with the contact 5 cannot be energized. Upon the disappearance of the fault condition the relay 9 becomes deenergized and, after a time delay, contacts 10 close to energize the coil 7 to open contact 5 thereby removing the short circuit from the capacitor 4 to return the link to its low impedance state.
