Abstract: Disclosed are solid, readily water-soluble addition polymers of acid addition salts of methacrylic acid and a 2-mono(lower)alkylaminoethyl methacrylate, whose lower alkyl group has up to 6 carbons and is straight or branched chain or cyclic. These polymers are insoluble in pentane, hexane and butane below their boiling points, and their aqueous solutions show amphoteric activity. These polymers result from polymerizing the starting monomeric acid addition salt of methacrylic acid and a 2-mono(lower)alkylaminoethyl methacrylate in the ratio of from about one mol to about 1.5 mols of one of them per mol of the other. Also disclosed is the method of producing these addition polymers by heating the starting acid addition salt under pressure in a low boiling aliphatic solvent at a temperature above its boiling point, from which after lowering the temperature the resulting addition polymer readily is separated as a light weight finely divided product.

Abstract: Method and apparatus of concentrating solids from a suspension by feeding material in a liquid medium to a first zone that includes a vertically oriented foraminous filter basket supported by circular bands which are connected to an open frame basket supporting cage. Rotary impeller arms significantly spaced from the basket inclined from the vertical and located about midway of the lower half of the basket impart a circular laminar movement to the material. A vertical cylindrical tank surrounds the basket. Filtrate is collected in the annular region between the basket and tank. Discharge outlets with rate of discharge controls extend outwardly and downwardly from the bottom of the separator apparatus. Operation can be batch or continuous with level of filtrate in the tank being maintained on a par with the level of the feed in the basket.

Abstract: Disclosed and claimed is the preparation of the 4-aminomethyl-cyclohexane carboxylic acid isomer assaying at least about 90% antifibrinolytically active material from specific para-disubstituted cyclohexane starting material. For example, in 4-aminomethyl-cyclohexane methanol such as its isomer melting at 118.degree. C. in a series of steps its methanol group is converted to carboxyl. More specifically its amino group is blocked by reaction with benzoyl halide and the methanol group then oxidized to carboxyl, and the benzoyl group removed to yield the end product isomer.1-4-dimethyl-cyclohexane dicarboxylate melting at 69.degree.-71.degree. C., another such cyclohexane starting material, is hydrolyzed to its mono-ester which with thionyl halide is converted to the halide of the half-ester, which latter reacted with ammonia gives the corresponding ester amide.
