Title: Improvements in or relating to the production of hydrocarbons of low boiling point by the hydrogenation of vapours obtained by distilling or cracking oils, tars and similar hydrocarbons
IPC: C10G47/00
Filed: 1933-11-03
Abstract: Hydrocarbon vapours obtained by distilling or <PICT:0428217/III/1> <PICT:0428217/III/2> cracking oils, tars, &c. are hydrogenated to produce fractions of low boiling point by mixing the vapours with a hydrogenating gas and passing the mixture through a purifier containing in the direction of flow of the gases iron, copper, and nickel, and then through a hydrogenating catalyzer, preferably containing nickel, vanadium and cobalt as catalysts.  A small quantity of nickel may be added to the iron and the copper, and the purifying catalysts are regenerated by first passing air through them and then an industrial gas containing hydrogen.  When the vapours are produced by cracking the hydrogenating gas is obtained by the interaction of steam with the coke formed in the cracking, while when the vapours are produced by distillation they are mixed with any gas containing at least 25 per cent hydrogen, e.g. water gas, blastfurnace gas, &c.  Oxygenated compounds are reduced by passage over calcined Cuprene (a porous composition formed by treating finely divided copper with acetylene) the products from cracking retorts 1 are passed through a dephlegmator 6 to vertical multi - tubular purifiers 11 arranged in pairs followed by an auxiliary purifier 12 and then through reducing and hydrogenating catalyzers 13, 14 to a condenser 15 from which the gases are passed through a vessel 16, where residuary vapours are removed by absorption in actuated carbon to a holder 17.  The cracking retorts 1, Fig. 1, are divided longitudinally by baffles 4 into compartments for retaining the coke formed and the oil is injected through an atomizer surrounded by a cooling jacket 3 while vapours pass off through an outlet 10.  A steam inlet 7 and an inlet 10 for hydrogenating gases, when the oils are distilled only, are provided.  Examples are given of the treatment of fuel oil, low and high temperature tars, creosote, benzoles, and phenol oils.

Title: Manufacture of new imidazolines
Filed: 1946-10-16
Abstract: 2 : 21-Diphenylene-4 : 41-bis-imidazolines are prepared by reacting a diphenyl-4 : 41-dicarboxylic acid or a functional derivative thereof, e.g. a nitrile, imino-ether, amide, thioamide, imino-thioether, halide, imino-halide, ester or amidine, with an alkylene diamine of which the amino groups are attached to vicinal carbon atoms.  The acid derivatives may be formed in situ.  Thus, the thioamide may be formed by using the corresponding nitrile in the presence of hydrogen sulphide or agents yielding hydrogen sulphide such as metal or non-metal sulphides.  Suitable alkylene diamines are ethylene - 1 : 2 - diamine, propylene - 1 : 2 - diamine and butylene-2 : 3-diamine. Reaction may take place in the presence or absence of water or an organic solvent with or without a condensing agent.  In examples: (1) ethylene-1 : 2-diamine is refluxed with diphenyl-4 : 41-dicarboxylic acid imino-ethyl ether dihydrochloride in alcohol to give 2 : 21-[diphenylene-(4 : 41)]-bis-imidazoline which is isolated as the hydrochloride, instead of the imino-ethyl ether dihydrochloride the imino-ethyl thioether dihydrochloride or the imino-chloride may be used; (2) diphenyl-4 : 41-dicarboxylic acid is heated with ethylene-1 : 2-diamine in the presence of hydrochloric acid to give the product of (1), the same product is obtained by using the disodium salt of diphenyl-4 : 41-dicarboxylic acid and ethylene-1 : 2-diamine dihydrochloride or by using a dilute aqueous solution of ethylene-1 : 2-diamine or by replacing the diphenyl-4 : 41-dicarboxylic acid by an ester or an amide; (3) diphenyl-4 : 41-dicarboxylic acid nitrile is treated with hydrogen sulphide and ethylene diamine to give the product of (1) the same product is obtained by the action of ethylene diamine on diphenyl-4 : 41-dithio-carboxylic acid amide; (4) diphenyl-4 : 41-diamidine reacts with ethylene diamine to give the product of (1); (5) diphenyl-4 : 41-dicarboxylic acid chloride reacts with ethylene diamine to give the product of (1); (6) the di-sodium salt of diphenyl-4 : 41-dicarboxylic acid and propylene-1 : 2-diamine dihydrochloride react to give 2 : 21-[diphenylene-(4 : 41)]-4 : 41-(or 5 : 51) - dimethyl - bis - imidazoline as the dihydrochloride; and (7) the disodium salt of diphenyl-4 : 41-dicarboxylic acid reacts with butylene-2 : 3-diamine hydrochloride to give 2 : 21-[diphenylene-(4 : 41)]-4 : 5 : 41 : 51-tetramethyl-bis-imidazoline.  Diphenyl-4 : 41-dicarboxylic acid imino-ethyl ether dihydrochloride is prepared by passing dry hydrogen chloride gas into a suspension of diphenyl-4 : 41-dicarboxylic acid nitrile in chloro-form-ethanol.  Diphenyl-4 : 41-dithio-carboxylic acid amide is prepared by treating the nitrile with hydrogen sulphide.  Diphenyl-4 : 41-dicarboxylic acid imino-ethyl thioether dihydrochloride is prepared by treating a solution of diphenyl-4 : p 41-dicarboxylic acid nitrile and a slight excess of mercaptan in chloroform with dry hydrochloric acid.

Title: Improvements in or relating to type printing telegraphy
IPC: H04L7/00
Filed: 1937-07-10
Abstract: 498,710. Type - printing telegraphy. STEVENS, A. H. (International Business Machines Corporation) July 10, 1937, No. 30856. Divided out of 497,102. [Class 40 (iii)] The type baskets at sending and receiving stations are brought into corresponding positions on the transmission of a check signal, so as to ensure identity of type-case irrespective of their relative initial positions. In a system in which the signals are single timed impulses, depression of the shift key 156 at the sending station, where switches 8, 11 are set to the right as shown, mechanically effects case-shift at the local station whether the transmitter is in the upper or the lower case, and also sends a case-shift signal to line by connecting battery to segment 16b of the distributer. For ensuring that when the type basket at the sending station is in the lower-case position that at the receiving station shall conform, a check key 256 is provided and the type basket 201 operates a switch 203. Depression of the check key 256 at the sending station causes a check signal to be sent to line 30, 31 through distributer segment 16c. At the receiving station, where switch contacts 8, 11 have been set to the left, the signal is received on the corresponding segment 16c and, if the type basket 201 is in its upper position, energizes magnet 158 to actuate the shift key 156 ; but if the type basket is in its lower position the circuit is broken at 203 and no shift occurs. In a modification, Fig. 2 (not shown), both the shift signal and the check signal are sent under the control not of a manual key but of a switch corresponding to 203 and operated by the type basket; and the check signal is sent whether the transmitter is in the upper or the lower case. The shift impulse determined by the movement of the type basket at the transmitter is momentarily stored in a condenser at the sending station, and the condenser is subsequently discharged to line through segment 16b for upper-case shift and 16c for lower-case shift. Specification 497,102 is referred to.
