Abstract: 875,015. Vapour burners. MEVA NARODNI PODNIK. Dec. 20, 1957, No. 39627/57. Class 75(1). In a kerosene noisy vapour burner in which kerosene under pressure is fed through feed pipes 2 to a vaporization chamber 3 and the vapour led through a U-shaped pipe 4 and nozzle 5 supported thereby to direct the vapour into a mixing chamber 6, the combustion control device comprises a funnelshaped annular member 9 which communicates with the mixing chamber 6 and is received by an annular ledge 3<SP>1</SP> and has thereon a baffle plate 8 of a diameter slightly less than the maximum diameter of the funnel and so positioned to form a peripheral gap 13 between the funnel 9 and plate 8. The plate 8 is supported on the funnel 9 by three equi-angularly spaced clips 12. The design lends itself to easy conversion to a noiseless burner by replacing the items 8 and 9 by a combustion control device in the form of a guide cap covered by a spaced perforated cap.

Title: Preparation of polyesters
IPC: C08G63/78
Filed: 1961-11-10
Abstract: <PICT:0952124/C3/1> In a method of making polyesters by reacting a polyol with a polycarboxylic acid or anhydride in the substantial absence of a solvent and whilst passing an inert gas through the reaction mixture, the mixture of gas and vapours removed from the reaction is passed directly to a condensation zone maintained at 213 DEG -240 DEG F. whereby polyol vapours are condensed and returned to the reaction mixture whilst water vapour and inert gas are allowed to escape; the rate of flow of inert gas through the reaction mixture in cu.ft./min. during the main part of the reaction being equal to 4+K.G. wherein K is 0.001-0.04 and G equal gallons (U.S.) of reaction mixture. Specified polyols are ethylene-, propylene-, butylene-, diethylene-, triethylene-, dipropylene- and tripropylene-glycols and glycerol.  Specified polycarboxylic acids and anhydrides are succinic, adipic, maleic, fumaric, phthalic, isophthalic, terephthalic, endomethylenetetrahydrophthalic, tetrachlorophthalic and tetrahydrophthalic.  The reaction mixture is charged to a reactor 10 provided with a heating jacket 13, an internal heating coil 13A and a stirrer 19. Inert gas at a slow rate of flow is introduced via a distributer head 20. Vapours and inert gas evolved from the reactor pass through line 21, trap. 22 and line 23 to a multi-tubular heat-exchanger 24 which is heated to 213 DEG -240 DEG F. After a time, an exothermic reaction takes place and heating of the reactor 10 may be discontinued for a while. The heating is continued and the rate of flow of inert gas is increased.  Polyol condensed in the heat-exchanger 24 trickles as a thin film down the inner surface a conduit 23 and any water in it is stripped out by the upwardly flowing gases and vapours.  The polyol then falls into the trap 22 from where it is returned to the reactor 10. Uncondensed water vapours are discharged from the system via a condenser 34. Examples describe the manufacture of polyesters by reacting (1) Maleic anhydride, phthalic anhydride and propylene glycol; (2) Maleic anhydride and diethylene glycol followed by the addition of phthalic anhydride and propylene glycol and further reaction; (3) Maleic anhydride, isophthalic acid and propylene glycol; (4) Maleic anhydride, phthalic anhydride, propylene glycol and diethylene glycol.
