Title: Improvements in and relating to the production of polymeric esters
IPC: C08G63/664
Filed: 1948-05-12
Abstract: Polymeric esters, which when of melting point above about 100 DEG  C. can be melt-spun and drawn into fibres, are produced by autocondensing by the action of heat an aromatic compound having the general formula <FORM:0641320/IV (a)/1> in which A is hydrogen or an acyl group, R is hydrogen or an alkyl group, m is an integer from 2 to 4 and n is an integer from 1 to 4.  The heating is carried out at about 200 DEG  C. or higher, and may be performed under reduced pressure.  The water, alcohol, fatty acid or ester which is formed (depending on the radicals A and R) is preferably distilled off as it is formed.  Suitable compounds are (a) para-(b -hydroxyethoxy)-phenyl acetic acid; (b) b -para-(b -hydroxyethoxy)-phenyl propionic acid; (c) g -para-(b -hydroxyethoxy)-phenyl butyric acid, or their methyl or ethyl esters.  The preparation of such compounds is described (see Group IV (a)).  The condensation is carried out in an inert atmosphere, and suitable catalysts are para-toluene sulphonic acid, sodium methoxide, aluminium ethoxide and lithium methoxide. In examples: (1) para-(b -hydroxyethoxy)-phenyl acetic acid and a para-toluene sulphonic acid catalyst are heated at 210 DEG  rising to 280 DEG  C. for 20 minutes at atmospheric pressure and then at 285 DEG  C. and 0.7 mm. for 6 hours, in a nitrogen atmosphere.  The product has an intrinsic viscosity of 0.41 and fibres of it can be cold-drawn.  Under similar conditions, polyesters are formed from (2) b -para-(b -hydroxyethoxy)-phenyl propionic acid; (3) the methyl ester of the acid used in (2); (4) g -para-(b -hydroxyethoxy)-phenyl butyric acid.  Specification 604,985 is referred to.ALSO:Acids of the formula <FORM:0641320/IV (b)/1> where m is 2, 3, or 4, and n is 1, 2, or 3 for use in the preparation of polyesters by autocondensation (see Group IV (a)) are prepared by reacting an acid of the formula <FORM:0641320/IV (b)/2> with ethylene chlorhydrin, trimethylene chlorhydrin, or tetramethylene chlorhydrin acetate respectively in the presence of alkali.  The products may be acylated or esterified by standard methods.  Examples describe the preparation of (1) p-(b -hydroxyethoxy)-phenyl acetic acid from p-hydroxy phenyl acetic acid and ethylene chlorhydrin; (2) b -p-(b -hydroxyethoxy) - phenyl propionic acid from b -(p-hydroxyphenyl) propionic acid and ethylene chlorhydrin; (3) the methyl ester of the acid of (2); (4) g  - (p - (b  - hydroxyethoxy)phenyl) butyric acid from g -(para-hydroxyphenyl) butyric acid and ethylene chlorhydrin.

Title: The production of crystalline penicillin salts
IPC: C07D499/00
Filed: 1949-05-16
Abstract: A crystalline penicillin salt is produced from another salt of penicillin by bringing a solution of the latter in an anhydrous organic solvent into contact with a cation exchanging substance charged with cations of the metal or base whose penicillin salt it is desired to produce, and then crystallizing the salt obtained from the solution.  The solvent may be a polar solvent (e.g. an alcohol) or a mixture of such solvents with one another or with a non-polar solvent (e.g. chloroform).  Crystallization may be effected by addition of a non-solvent, or the ion exchange process may be carried out at an elevated temperature (preferably using n-butanol as solvent), and the solution then cooled.  In examples: (1) a solution of potassium penicillin in methanol is passed through a column of sodium-charged Amberlite IR-100, and sodium penicillin is precipitated in crystalline form by addition of ether to the resulting solution; (2) the triethylamine salt of penicillin is similarly treated, except that crystallization of the sodium salt is effected by adding n-butanol and distilling off the methanol in vacuo; (3) the N-ethylpiperidine salt of penicillin is treated as in (1); (4) a solution of the penicillin salt of diethylaminoethyl p-aminobenzoate in a mixture of alcohol and acetone is passed through a column as in (1), isoamyl alcohol is added to the resulting solution and the original solvents are distilled off in vacuo.  Reference is also made to calcium penicillin as a product, ammonium penicillin as a starting material, propanol as a solvent, and amyl acetate as a non-solvent. Specification 595,798 is referred to.  The Specification as open to inspection under Sect. 91, comprises also the production of penicillin acid by the use of a cation-exchanging substance charged with exchangeable hydrogen ions.  This subject-matter does not appear in the Specification as accepted.

Abstract: 553,345. Terminals for suspended ways; winding-apparatus. MELLING, J. Oct. 14, 1941, No. 13240. [Classes 78 (iv) and 78 (v)] Terminals for suspended ways. The load 9 of a hoist is suspended by an open sided runner 8 in a bight 7 of a rope passing (1) over a fixed guide 4 down an incline 1 to a delivery point 2 and (2) over a guide pulley 11, higher than the guide 4, to a winch 12 or other hauling means. Thus, when the rope is hauled in the load is raised until it is slightly above the guide 4, the rope then passing direct from the pulley 11 to the guide, so that the load can then run down the incline 1 and be automatically delivered at the point 2. A weight 15, less than the load 9, re-forms the bight 7 when the rope is released. The guide 4 and pulley 11 may be carried by any fixed members or, as shown, by a mast 6, and the arm 5 carrying the guide may swivel about the mast. Overwinding, preventing. When the load is raised by power, means are provided for automatically declutching the drive as the load reaches the guide 4. In the construction shown in Fig. 3 the hoisting rope is wound on a drum 23 driven by a motor 25 and passes over a pulley 21 carried by weighted arms 22 pivoted on the drum shaft. When the hoisting rope tightens between the pulley 11 and guide 4 the rope tension raises the pulley 21 and arms 22 so that a cam 24 on one of the arms disconnects a clutch between the motor and the drum. The weight of the pulley 21, and of an adjustable weight 26 if necessary, is sufficient to overbalance the weight of the load 9. Alternatively the load or its runner 8 may disconnect the drive when it reaches its highest point.
