Patent GB-476898-A (GB)
Title: Manufacture of esters of salicylic acid
IPC: C07C69/88
Filed: 1936-06-24
Abstract: Esters of salicylic acid with phenol and homologues thereof are manufactured by heating a salicylic ester of an alcohol of low boiling point with phenol or a homologue thereof in the presence of a catalyst consisting of an alkali or alkaline-earth metal salt of phenol or a homologue or substitution product thereof or a mixture of such salts.  The catalyst may be prepared by dissolving an alkali or alkaline-earth metal in the mixture of the phenol and salicylic ester used as starting material, or it may be prepared separately by the action of an alkali or alkaline-earth metal on a phenolic compound, especially the phenol or salicylic ester used as starting material or the salicylic ester forming the product of the reaction, or by using a caustic alkali or an alkaline-earth oxide or hydroxide instead of the metal and removing the water formed from the catalyst before use, taking care to avoid saponification when the catalyst contains an ester group.  The reaction temperature should be such that the alcohol liberated is continuously distilled off.  In order to avoid reactions of condensation of the salicylic esters, the phenol is preferably used in excess and it is advisable to interrupt the reaction when 60 per cent of the parent salicylic ester has undergone conversion, the catalyst then being removed by washing or decomposed with acid and the unchanged reactants distilled off under reduced pressure and, if desired, used in a subsequent batch, the operation being repeated several times if necessary. In examples: (1) sodium is dissolved in a dry mixture of phenol and methyl or ethyl salicylate which is then heated to boiling; (2) phenol and methyl salicylate are heated with the sodium salt of methyl salicylate, prepared by reacting caustic soda with methyl salicylate in alcohol, filtering and drying the precipitate; (3) thymol, or "Iso-thymol oil," is heated with methyl salicylate and the sodium salt thereof.

Title: Improvements in and relating to x-ray apparatus
IPC: H05G1/54
Filed: 1943-11-01
Abstract: 569,547. Supply systems for X-ray apparatus. BRITISH THOMSONHOUSTON CO., Ltd. (General Electric Co.). Nov. 1, 1943, No. 18002. [Class 38 (iv)] [Also in Group XL] The anode 13 of an X-ray generator 17 is heated electrically for an interval after the tube has been producing X-rays for a short limited exposure interval in order to retard cooling of the anode to prevent it cracking. The tube 17 is provided with current by a transformer 21 through rectifiers 19. The transformer 21 is connected to an autotransformer 31 across the mains 33 by a switch 29. The latter is operated by a solenoid 35 controlled by a time switch 39 and operating switch 41. The anode heating may be effected by an inserted heating element, but preferably as shown is effected by operating the tube at a potential too low to generate X-rays. This is effected by a switch 43 which connects transformer 21 to the autotransformer 31 through a resistance 45. Switch 43 is operated by a solenoid 47 controlled by a time delay switch 51. This latter requires a longer period to open than switch 39 and thus the tube is operated for a fixed period at a lower voltage after the period of full operation.
