Abstract: A conveying apparatus is disclosed for conveying pallets upon which cement is deposited for continuous moulding of cement tiles. The pallets each have a projecting shoulder portion and are of predetermined length and the apparatus includes a support over which the pallets are conveyed in a continuous stream with adjacent pallets in contact with one another, the drive mechanism for moving the pallets along the support, said drive means including an endless band located above the support and having a run in the direction which the pallets are conveyed over the support, the band having drive members projecting outwardly therefrom for engagement with the shoulders of the pallets for moving the pallets.

Abstract: A novel mixing apparatus for pulverent material, slurries and paste like material is disclosed. The apparatus is especially suitable for mixing cement and sand into mortar. The mixing apparatus comprises a casing having a cylindrical inner surface and a screw member mounted within the casing for rotation relative thereto about an axis which is coaxial with the axis of the inner surface, characterized in that the screw member includes a plurality of flights which at least approximate portions of a helical screw but which are arranged such that the tailing portion of one flight overlaps, as viewed axially, the leading portion of the next succeeding downstream flight. The overlapping flights promote turbulence in the flow which ensures good mixing.
