Title: New salts of penicillin with alkylene diamines and processes of making them
Inventor: SZABO JOSEPH LESTER
IPC: C07D499/00
Filed: 1955-01-26
Abstract: The invention relates to salts of penicillin with alkylene diamines of general formula <FORM:0777380/IV(b)/1> wherein each R1 substituent represents an alkyl radical containing from 1 to 7 carbon atoms and alk stands for an alkylene radical of 2 to 12 carbon atoms either in a straight chain or branched chain form.  The salts are prepared by reacting penicillin, or a salt thereof, with the appropriate alkylene diamine, or a salt thereof, the reaction being carried out in the presence of a solvent.  The free acid and base is reacted in a non-aqueous solvent such as ether, acetone, ethyl acetate and amyl acetate.  Salts are reacted in an aqueous medium.  The penicillin salt may be an alkali metal or an alkaline earth metal; and the penicillin penicillin G, dihydro F, X, K or a mixture thereof. The diamine salt may be a salt with an inorganic or organic acid, e.g. acetic, lactic, succinic, malic, aconitic or tartaric acid. The salts of penicillin and the diamine may be mono- or di-salts. The example relates to the preparation of N,N1-di-(a -methylbenzyl ethylene diamine dipenicillin.  The salts are non-toxic and may be used therapeutically.  They are also used in the purification of penicillin.  The N : N1-disubstituted diamines may be prepared by reacting a ketone of formula <FORM:0777380/IV(b)/2> where R1 stands for a 1 to 7 carbon alkyl group with an alkylene diamine to form a di-imine which is then reduced catalytically by means of hydrogen. In the example, acetophenone is reacted with ethylene diamine and the di-imine so produced is hydrogenated in glacial acetic acid using a platinum oxide catalyst.  Specification 716,556 is referred to.

Filed: 1923-02-03
Abstract: 193,035. Naamlooze Vennootschap Ingenieursbureau Securitas. Feb. 11, 1922, [Convention date]. Electric machines for coding and decoding; counting- apparatus.-An electric ciphering-machine is provided with a counting-mechanism adapted, when a predetermined number of signs have been ciphered, to modify the operation of the machine (for instance by stopping the machine, operating a signal bell or lamp, or inserting a sign or abnormal space) and thereby enable the beginning and end of a group of signs to be recognized. A keyboard 1, Fig. 1, is electrically contacted with a strip perforator or a typewriter 12 through drums 4, 10 for clear text, and through drums 4, 6 - - 9, 11 for cipher text. The drums 10, 11 are stationary, drum 4 being loosely mounted on a shaft 5 for longitudinal movement by a lever 27, and drums 6 - - 9 being rotated on the shaft by a driving-wheel 15, spur wheel 18, and gear wheels 16, 17, 21, 22 of different transmission ratios. An electromagnet 26 is energized bv an electric connection 2 common to all the key circuits, and its armature 25 carries a blade spring 24 engaging with the teeth cf the driving-wheel 15 mechanically operating a counter 39 after each sign has been ciphered. Each number disc of the counter is provided with an inset insullating plate 50 - - 52 and rubbing contacts 40 - - 44 connected in parallel by switches 45 - - 49, so that the counter can be set to break the circuit of the electromagnet 26 after a predetermined number of signs have been ciphered. In this condition a lamp may be lighted or a bell sounded. When reverting to clear text the lever 27 is depressed, putting drums 4, 10 into electric connection. and making contacts 31, 32, the latter operation short-circuiting the electromagnet 26 and counting-mechanism. When the lever is returned contacts 31, 32 are broken and contacts 30, 33 established, the counting-mechanism alone, being then short-circuited. After the next cipher sign has been made the full upward throw of the armature 25 causes a blade spring 36 to engage a groove 37 in the armature and lift a pawl 35 to restore the normal electrical connections. Letter-spacing mechanism.-The Specification. as open to inspection under Sect. 91 (3) (a), describes also arrangements for spacing the cipher obtained into groups of five signs. A relay 53, Fig. 2 (Cancelled). in circuit with the electromagnet 26, operates an armature 55 carrying a spring pawl 56 engaging a ratchet wheel 59 having a disc 60 secured to it. The disc is provided with a pin 61 which engages with a projection 62 on a plunger 63 and makes contact between springs 68, 69 energizing the spacing- magnet 70. The plunger acts in a cylinder 65 to which air is admitted through a. valve 67 and can pass slowly through a port 66 to ensure the spacing contact being of sufficient duration. Alternatively, as shown in Fig. 3 (Cancelled). the paper-carriage rack 71 is provided with enlarged gaps 73 at regular intervals. This subject-matter does not appear in the Specification as accepted.

Abstract: Semi-elastic materials of cellular structure are made by reacting a linear polyester having a molecular weight less than 1000 with an excess of an organic diisocyanate over the amount calculated on the end groups, and reacting the product with water. Reaction between the polyester and the diisocyanate may be performed in presence of a retarding agent, e.g. hydrochloric acid, butadiene sulphone or acetyl chloride, or an accelerating agent.  Fillers or disinfectants may be added prior to the blowing reaction.  Specified polyesters are (a) aliphatic polyesters, e.g. polyglycol adipate (examples 1 and 2), polydiethyleneglycol adipate (example 3) or polyglycol succinate; (b) co-polyesters, e.g. from glycol, succinic acid and adipic acid (example 4); and (c) a mixture of a polyester from an aliphatic dicarboxylic acid with a smaller amount of a polyester from an aromatic dicarboxylic acid (e.g. phthalic acid).  In examples, the linear polyester is dehydrated in presence of hydrochloric acid and reacted with toluylene diisocyanate at below 120 DEG  C.  The condensate is then mixed with acetone and a mixture of hexahydrodimethyl aniline, an emulsifier and water is added to the mixture.  After stirring, the mass is cast into moulds.
