Title: Method of production water soluble physiological acceptable staron esters
Inventor: FORSTER HARALD
IPC: C08B31/04
Filed: 1992-07-09
Abstract: In order to prepare physiologically tolerated water-soluble starch esters, the invention proposes that starch is converted by acid hydrolysis or enzymatic hydrolysis to a partially hydrolysed form with a mean molecular weight in the range from 10,000 to 500,000 Daltons. This partial hydrolysate is then acylated, in aqueous solution, with the anhydride or halide of an aliphatic monocarboxylic acid with 2 to 4 carbon atoms or an aliphatic dicarboxylic acid with 3 to 6 carbon atoms, or mixtures thereof, and an alkalinization agent, to give a product with a substitution ratio in the range from 0.1 to 1.0 mole/mole. Salts are removed from the resulting reaction mixture. The starch esters thus obtained are highly suited for clinical use, in particular parenteral administration and administration in the diet.

Title: Method of separating mixture of liquids and solid substances, and apparatus for making the same
Inventor: GUGGEMOS HORST
IPC: B01D25/12
Filed: 1992-01-29
Abstract: The invention concerns a method and device for separating mixtures of liquid and solid materials by squeezing out or filtering off the liquid component. The mixture is divided into a multiplicity of adjacent or consecutive portions which are simultaneously and jointly compressed or reduced in size by the action of an external compressive force which is substantially the same for all portions and which acts in the direction in which the portions are disposed next to each other, and is propagated through all the portions. The solids in the portions are retained as filter cake, while the liquid is squeezed out as filtrate. The invention calls for the filtrate squeezed out of the portions, or out of the filter cake formed in the portions/filter cakes, to be removed through the end faces of the portions as well as through at least the bottom and, if possible, also the top surfaces, and preferably also through the sides, and advantageously through the entire top surface of the portions or filter cakes, i.e. through the end and peripheral surfaces of the portions/filter cakes.
