Title: Improvements in or relating to thiophene compounds and processes for preparing the same
IPC: C07D333/38
Filed: 1945-09-04
Abstract: 2-Carbalkoxy-3-keto-4-acylamido-tetrahydrothiophenes and their 2-alkali metal and 2-alkaline earth metal derivatives of the formula <FORM:0606189/IV(b)/1> wherein R is an acyl group, R1 is an alkyl, aryl or aralkyl group and X is hydrogen, an alkali metal or an alkaline earth metal are obtained by treating a 2-acylamido-3-carboxymethylmercaptopropanoic di-ester, preferably in an aliphatic alcoholic reaction medium, with an alkali metal alcoholate or an alkaline earth metal alcoholate.  Upon treating the metal derivative thus obtained with dilute acid at room temperature (30 DEG  C.) or below, the corresponding free ester can be obtained. By treating either the metal derivative or the free ester with reagents showing reactivity towards the keto group other derivatives are produced, e.g. the oxime, aryl hydrazone, semi-carbazone and simple keto-addition products.  In an example, the 2-sodium derivative of 2-carbomethoxy-3-keto-4-benzamido-tetrahydrothiophene is produced, from which is obtained the oxime and the phenyl hydrazone after hydrolysis to the ester whilst the semi-carbazide and nitrophenylhydrazone may be produced directly from the metal derivative.  Specifications 606,188 and 606,196 are referred to.

Title: Improvements relating to steam generating apparatus
Inventor: GUNN DAVID CHALMERS
IPC: F22G3/00
Filed: 1965-05-28
Abstract: 1,089,583. Protecting superheater tubes. COCHRAN & CO., ANNAN, Ltd. May 20, 1966 [May 28, 1965], No.22790/65.' Heading F4A. On start up of a steam generator, the superheater 2 is filled with demineralized water from a reservoir 3, supplied through an inlet passage containing a non-return valve 5 and control valve 4. Since main stop valves 16 and 15 and drain valve 15 are closed, the filling continues until discharge passage 8 containing control valve 9 is filled to level 10. On firing, the demineralized water expands up discharge passage 8 to steam and water separator 11, from where steam is discharged through line 13 to atmosphere, and water through line 12 to the reservoir 3, thereby establishing a thermosyphonic circulation. When sufficient steam from the boiler steam and water space is available, valve 4 is closed and valves 16 and 14 opened to pass boiler steam through superheater 2 to the drain. Once all water from the superheater start up circuit is drained away, main line valve- 15 is opened and valves 9 and 14 shut for normal operation. In a multiple generator installation, each generator preferably has its own. separate reservoir which has a capacity such that it is nearly emptied by completion of the start up cycle.

Title: Process for the manufacture of stable calcium thiosulphate solutions
IPC: C01B17/64
Filed: 1936-08-27
Abstract: All traces of sulphur are removed from aqueous calcium thiosulphate solutions whereby they are rendered stable at above 80 DEG  C.  The removal of sulphur may be effected by filtration through Berkefeld or Seitz bacteria-retaining filters, or by absorption on animal charcoal, silica gel or other substances having a large absorptive surface.  Prior to the sulphur removal, the calcium thiosulphate is preferably purified by repeated crystallization.  In an example, very finely powdered sodium thiosulphate is added with stirring to a concentrated calcium chloride solution at 45--50 DEG  C., and sodium chloride is allowed to separate.  The filtrate is cooled to 0 DEG  C. to crystallize calcium thiosulphate, which is filtered with suction on a glass filter. The crystals are dissolved in a relatively small quantity of water at 70--80 DEG  C., and the solution filtered with suction through an ordinary filter to remove as much as possible of the undissolved sulphur and sodium chloride.  The filtrate is crystallized in an ice chest, the crystals dissolved in water at 60 DEG  C., and the solution filtered with suction through an ordinary filter and crystallized at 0 DEG  C.  The crystals are dried in a vacuum desiccator over sulphuric acid, the drying being advantageously effected in a stream of dry nitrogen at room temperature.  The dried crystals are dissolved in distilled water to form a 10 per cent solution which is filtered through a Berkefeld filter.  The stable solution is applicable therapeutically and may be administered intravenously.  It can be sterilized by heating with the exclusion of air at 98 DEG  C., for ten hours without decomposition. Air should be excluded from all stages of the purification.  The Specification as open to inspection under Sect. 91 comprises also the precipitation of stable crystalline calcium thiosulphate from the 10 per cent stable solution by adding thereto an organic solvent such as alcohol until the liquid consists of 50 per cent water.  This subject-matter does not appear in the Specification as accepted.
