Abstract: 346,718. Moulding and decorating pipes &c. by extrusion machines. PAISSEAU, J., 5, Rue Blondel, Courbevoie, Seine, France. Jan. 15, 1930, No. 1497. [Class 87 (ii).]- The central stud or core in the orifice of an extrusion machine for producing tubes, rods, and the like, is provided with a series of protuberances or bosses 7 which commence short of the exit 9 and are arranged at different points along the axis of the core and spaced around same. In some cases the bosses may be arranged to form an interrupted helix, or the whole stud may be shaped as a helix of long pitch. By the aid of the core, plastic material charged with glittering particles is decorated during the extrusion process by orientation of the particles so as to produce a tube or rod with transversely or obliquely waved designs. The core may also be reciprocated during the extrusion process, for example as shown in Fig. 3, in which the members 15 are suspended by flexible strips 14 from a rigid bar so that they are reciprocated by the pressure of the material. The apparatus is applicable specially to the manufacture of celluloid, the heated material being forced into the nozzle through tangential holes 1 and being heated subsequently by fluid circulated through the holes 3. For forming rods and other solid bodies the central stud diminishes progressively to, and ceases at, a point some distance short of the exit 9..

In a machine for sorting objects according to their colour, the objects to be sorted fall through a pipe 2 in which is a sliding valve 4 into a vibrating conveyer 5. This conveyer makes an angle to the horizontal of between 6 and 10 degrees and is vibrated by a solenoid the line of action of which is at 50 degrees to the base of the conveyer. The objects then fall on to an endless V-shaped belt 6 passing over pulleys 8, and then enter a tube 10, the curvature of which is such that the objects enter it without change of direction from the belt but then slopes more steeply so as to enter the viewing compartment at an angle of 70 degrees to the horizontal. The viewing chamber comprises light sources 16 and photo-cells 12, 13 " looking at " the falling objects against comparison backgrounds 14, 15. Detection of an object differing in colour from the background operates an electromagnet to open a valve so that a jet of air from pipe 17 deflects the object which would otherwise fall into tube 19 into tube 18.
