Title: Processes for manufacturing therapeutically valuable salts of penicillin g
IPC: C07D499/00
Filed: 1948-09-20
Abstract: A process of preparing alkali metal and alkaline earth metal salts of penicillin G comprises metathetically reacting in solution in a polar organic solvent an amine salt of penicillin G and an alkali metal salt or an alkaline earth metal salt or an alkali metal derivative of an active methylene compound.  The process of preparing alkali metal salts of penicillin in which a salt of penicillin and an organic base which will form crystalline salts with it, is reacted with an alkali metal salt of an aliphatic or substituted aliphatic acid is, however, disclaimed. Solvents specified are chloroform, b ,b 1-dichloro-dialkyl ethers, nitroparaffins, e.g. nitromethane, acetone, methyl ethyl ketone, ethyl acetate, alcohols, e.g. ethanol, butanol, 2-ethyl-butanol, nitriles, e.g. acetonitrile, and mixtures of those solvents.  As amine salts are specified salts of penicillin G with trimethylamine, triethylamine, N-methyl-piperidine, N-ethyl-piperidine, N-methyl-morpholine and N-ethyl-morpholine. The alkali metal compound or alkaline earth metal salt preferably has a solubility in the solvent employed substantially greater than the solubility of the corresponding metal salt of penicillin G. Specified are halides, e.g. sodium iodide, potassium iodide, lithium chloride, calcium bromide, alkali metal thiocyanates, and alkali metal compounds of active methylene compounds, e.g. sodium acetoacetic ester.  Examples describe reacting together a chloroform solution of the N-ethyl-piperidine salt of penicillin G and an acetone solution of (1) sodium iodide; (2) sodium thiocyanate; (4) lithium chloride; (5) calcium bromide.  Also reacted are (3) a chloroform solution of the triethylamine salt of penicillin G and an acetone solution of sodium iodide; (6) a n-butanol solution of the N-ethyl morpholine salt of penicillin G and an ethanolic solution of sodio-acetoacetic ester.  The Specification as open to inspection under Sect. 91 comprises as alternative reactants alkali metal salts of aliphatic carboxylic acids, e.g. sodium acetate hydrate, and sodium or potassium 2-ethyl-hexoate.  In examples there are reacted a chloroform solution of the N-ethyl-piperidine salt of penicillin G and a solution of sodium 2-ethyl hexoate dissolved in (2) and (7) acetone; (8) methyl ethyl ketone; (9 ethyl acetate; (10) 2-ethyl butanol; (11) butanol; (12) b ,b 1-dichloro-diethyl ether; (13) acetonitrile.  Examples (15) to (20) describe similar processes in which, however, the N-ethyl piperidine salt of penicillin G is dissolved in nitromethane.  In example (14) solid sodium 2-ethyl-hexoate is reacted with a chloroform solution of the N-ethyl piperidine salt.  A slurry of sodium acetate hydrate in butanol is reacted with (21) the N-ethyl-piperidine salt of penicillin G in alcohol and (23) the cyclohexylamine salt of penicillins (predominantly G).  This subject-matter does not appear in the Specification as accepted.

Title: Mechanism for controlling winding of yarn
IPC: B65H63/06
Filed: 1965-06-10
Abstract: 1,098,798. Stop-motion; slub catcher; yarn-severing device. ABBOTT MACHINE CO. Inc. June 10, 1965 [June 10, 1964], No. 24578/65. Headings DID and D1J. Means for interrupting the winding of yarn when an enlargement other than one of short duration appears in the yarn, comprises a restricted passage for the yarn, means, responsive to increased tension in the yarn arising from an enlargement travelling through the passage, the responsive means then allowing the yarn to be deflected, into contact with cutting means, either the same tension responsive means or another being connected to a stop-motion to actuate it on the fall in tension caused by the cutting of the yarn. The enlargement may occur as a result of inadvertent doubling, and the device having a restricted yarn-passages may be a slub-catcher, e.g. of the kind described in U.S.A. Specification 2,623,265, which is ineffective as regards short enlargements. The invention is described in relation to winding-apparatus of the travelling- type a described in U.S.A. Specification 2,135,485. In Fig. 1, a head 10 is one of a number travelling by rollers 12 along a rail, and there is a fixed drive-drum 15 for a package P on which yarn is laid by a reciprocating guide .18. A feeler 310 pivoted at 312 has an extension linked to a member 362 pivotallyattached to a rotatable sleeve 360. The feeler is depressed owing to its resilience by the yarn when it is in tension; when the tension falls, the feeler rises and allows member 362 to pivot, so that as the head travels, it engages fixed dogs 318 and the sleeve 360 is .rotated to cause an arm 301 to lift the package off the drive-drum. The feeler operating in this way is adapted for the purposes of the invention. Yarn passes over the feeler after leaving guides 21, Fig. 3, tension-discs 30 and a slub-catcher 40 of the type above referred to. By adjusting a bolt 50 at the junction of the lower end of the feeler and the link, the feeler is positioned so that the yarn normally clears a snagging- lever 52. When an enlargement of objectionable length occurs in. the yarn, the catcher exerts sufficient drag in the yarn to raise its tension and cause it to depress the feeler, so that as the laying guide 18 reciprocates, the yarn engages the snagging-lever and is severed. The feeler then performs its normal function of lifting .the package off the drive drum. In Fig. 5, one side of the slub catcher consists of fingers 52a backed by rubber 51a and is adjusted at 60. On leaving the catcher, the yarn passes over a plug 64 and is kept clear of severing-fingers 71. When the tension rises, the yarn moves over a conical end of the plug and is lowered into contact with the fingers.
