Abstract

1,169,444. Continuous mixing apparatus. BADISCHE ANILIN-& SODA-FABRIK A.G. 24 Feb., 1967 [26 Feb., 1966], No. 8903/67. Heading B1C. [Also in Division C3] An apparatus for producing foams from curable synthetic resins comprises a tube 1 for supplying an aqueous foam, a line 2 arranged concentrically in 1 through which a solution of resin is introduced, and a cylindrical mixing vessel 5 at one end of which the tube 1 is laterally attached. A tube 3 leading into 1 serves to introduce a foamed solution of a foaming agent into 1. The end of 2 is provided with a constriction consisting of a thin-walled tube 4. At the top of 2 are two tangential branch connections 11 and 12 for introducing resin and compressed air respectively into 2. A stirrer shaft 6 arranged concentrically in 5 is provided with stirrer blades 8. A tangentially arranged outlet 9 is provided at the end of 5 opposite where 1 enters the mixing vessel. The mixture of foam and resin is discharged through 9 and passed through a hose 10 connected to 9.
