Title: Process and apparatus for the production of bitumens from acid resin residues
IPC: C10C3/00
Filed: 1930-07-21
Abstract: <PICT:0359461/III/1> Sludges obtained when purifying petroleum by sulphuric acid are heated to 80-100 DEG  C. under a pressure of more than 2 atmospheres so that on standing they separate into layers of acid, bitumen, and oil which are withdrawn separately.  The acid and oil are purified by known processes.  The bitumen is freed from acid &c. by forcing hot air, inert gas, or combustion or other waste gases through it and also on to the top surface.  For example, the bitumen is heated to 150 DEG  C. in a still S, and steam, air, or gas at 170-200 DEG  C. is forced in through a perforated pipe 1, and through fine nozzles in pipes 2, 3 to break the bubbles of foam. A foam leveller 4 is provided.  The acid passes off through the pipe P.  The purified bitumen is used as a basis for asphalt-varnish or acid-resisting paint; or as an insulating, impregnating, or casting mass for electrotechnical purposes or for making roofing felt, asphalt, and street pavements.ALSO:<PICT:0359461/IV/1> Sludges obtained when purifying petroleum by sulphuric acid are heated to 80-100 DEG  C. under a pressure of more than 2 atmospheres so that on standing they separate into layers of acid, bitumen, and oil which are withdrawn separately.

Title: Improvements in or relating to manufacturing soaps
IPC: C11D13/04
Filed: 1929-07-17
Abstract: 316,935. Henkel et Cie Ges. Aug. 6, 1928, [Convention date]. Soaps, processes and compositions for making. -Split or other fatty acids containing neutral fats are saponified by a continuous process in which the calculated quantity of alkali carbonate to combine with the free fatty acids is mixed with the fatty matter, the mixture is then passed through a heating device to complete the saponification of the free fatty acids, and finally is mixed with the caustic alkali necessary to convert the glycerides. Water-glass, or other filler, dye, bleaching liquid, or other addition may be made with the alkali carbonate or hydrate. For example, measured quantities of heated split fatty acids and sodium carbonate solution are fed through the pipes a, b respectively to a mixer e consisting of stationary or rotating sieves; the partly saponified mass falls on to inclined hot plates or layers of heating coils g, and then to a similar or other heated mixer, e.g. a sieve i into which the required caustic soda is sprayed from a pipe k. The finished soap falls to the bottom of the tower or boiler d and is pumped out continuously through the outlet l. Escaping steam and carbon dioxide are withdrawn through suction conduits m.
