Abstract
1412115 Mixing apparatus J BERNOLD 24 Nov 1972 [22 Dec 1971] 54347/72 Heading B1C [Also in Division El] Concrete is forced from a mixing container 1 by compressed air through an outlet pipe 5, 12, and two, three or four further streams of air are introduced into the pipe 5 through circumferentially spaced pipes 7, in order to improve the flow of concrete, the pipe 5, 12, being connected at 13 to a further pipe (not shown) from which the concrete is sprayed. The pipes 7 are radially directed and are connected by a ring pipe 8 to a connector 9 for a compressed air supply. The outlet pipe comprises a cylindrical portion 5 inserted into an outlet nozzle 2 of the mixer 1 and secured by a bayonet joint between flanges 3, 6, and a tapering portion 12, the pipes 7 feeding into the cylindrical portion 5.
