Title: New ditertiary diamines and diquaternary diammonium compounds and their production
Filed: 1952-09-03
Abstract: The invention comprises diamines of the general formula: <FORM:0715440/IV (b)/1> and diquaternary diammonium compounds of the formula: <FORM:0715440/IV (b)/2> where <FORM:0715440/IV (b)/3> is a dialkylamino radical, each alkyl group containing from 1 to 4 carbon atoms, or an alkylene-imino radical with 5-6 ring members having a maximum of 6 carbon atoms, e.g. pyrrolidino, piperidino or 2-methyl-piperidino, or the morpholino radical; R1 is an alkyl radical containing from 1 to 4 carbon atoms; Anis an anion; m is an integer of 6 to 14 and n is 1 to 4.  The diamines may be prepared by reacting the a ,o -bis-(halogen alkanoyloxy)-alkanes with 2 mols. of amines of the formula NHRR. These may then be treated with alkylating agents of the formula R1An1, replacing the anion An1 by a different anion, if desired, to give the quaternary compounds.  An1 may be chlorine, bromine, iodine, -O-SO2-OCH3 -O-SO2-OC2H5 or -O-SO2-aryl. Some of the quaternary compounds can be prepared directly by reacting the a ,o  - bis - (halogen - alkanoyloxy)-alkanes with 2 mols. of tertiary amines of the formula NRR.R1.  The reactions are preferably effected at elevated temperatures and solvents may be used, e.g. acetone, butanone, acetic acid ester, benzene, toluene, xylene, ether, dioxan, methanol or ethanol.  Specified starting materials are a ,o -bis-chloracetoxy-, a ,o  - bis - bromacetoxy -, a ,o  - bis - iodacetoxy-hexane, heptane, octane, nonane, decane, undecane, dodecane, tridecane and tetradecane, a ,o  - di - (b 1 - bromo - or b 1 - chloro - propionyloxy)-, a ,o -di-(g 1-bromo- or g 1-chloro-butyryloxy)- and a ,o -di-(d 1-bromo-d 1-chloro-valeryloxy)-hexane, heptane, octane, nonane, decane, dodecane and tetradecane.  These may be reacted with dimethylamine, methylethylamine, methylpropylamine, methylisopropylamine, methylbutylamine, methylisobutylamine, diethylamine, ethylpropylamine, ethylbutylamine, dipropylamine, di-isopropylamine, dibutylamines, piperidine, morpholine, pyrrolidine, 2-methylpiperidine, trimethylamine, methyl-diethylamine, triethylamine and 1-methyl-piperidine.  Suitable alkylating agents are methyl and ethyl iodide and bromide, ethyl chloride, propyl iodide and bromide, isopropyl bromide, butyl and isobutyl bromides, and dimethyl and diethyl sulphates.  The quaternary ammonium iodides or bromides can be converted into the chlorides by silver chloride. In the example: 1,10-di-(chloracetoxy)-decane, prepared by reacting chloracetyl chloride with 1,10-decane diol in a benzene/pyridine mixture, is heated with diethylamine in benzene to give 1,10 - bis - (a  - diethylamino - acetoxy) - decane.  This is then refluxed in acetone with ethyl iodide to give the di-iodide of 1,10-bis-(a -tri-ethylammonium-acetoxy)-decane.  The Specification names a number of compounds which may be similarly prepared.

Title: Telegraph switching systems
IPC: H04L12/04
Filed: 1930-07-24
Abstract: 359,538. Telegraph exchange systems. CONNERY, A. F., 22, Revere Place, Brooklyn, and INTERNATIONAL COMMUNICATIONS LABORATORIES, Inc., 67, Broad Street, both in New York, U.S.A. July 24, 1930, No. 22320. [Class 40 (iii).] In a printing telegraph system a branch station can establish a connection with a central station, provided with manually controlled means for rendering inoperative its telegraph apparatus and having further means responsive to the signal impulses from a branch station for automatically rendering operative the central station printing telegraph apparatus provided the connection has not been broken down. The apparatus at the branch office comprises a printer receiving magnet 1, keys 2, and a motor 5 set into operation on the release of the armature of a relay 3. The winding of the relay 3 is energized when a polarized relay 4 is operated by line current of negative polarity. When positive or no current is on the line the spring- biased armature of the relay 4 is released and relay 3 is short-circuited and de-energized. To obtain connection to the central station a key 15 is momentarily depressed to open the circuit of a winding 16 of the line relay 6, having an armature 17 which shunts the winding 16 to prevent the energization of relay 6 when the line is again closed by the key 15 ; and a second armature 18 which closes a circuit through a switchboard indicator lamp 8. On the insertion of an answering jack 9 into the sleeve 7, the lamp circuit is broken, and the connection of negative battery 19 to the line is interrupted. A circuit is completed from positive battery 20 through the sleeve 7, jack 9, printer magnet 12. and keys 13 of the central station apparatus and the winding of a relay 14 to the line, thus setting into operation the motor 5 at the branch office. The operation of relay 14 energizes through a condenser 26 a winding 22 of a relay 23, which through one armature closes the circuit of a motor 25 and by a second armature interrupts the circuit of lamps 10, 11 and closes for the relay 23 a locking circuit. The message is transmitted by the interruption of the positive current placed on the line by battery 20. The central station operator can disconnect his motor by breaking the circuit of the relay 23 at a key 38. Should the key 28 be depressed prematurely, provided the plug 9 is not removed, the continuation of the transmission of signal impulses from the branch station will energize the relay 14 which operates relay 23 to restart the motor 25 and lock up over winding 24. If separate switching and telegraph operators are not employed at the central station, the lamps 8 and the sockets for the jacks 9 are multipled, Fig. 2 (not shown), for the convenience of the operators.
