Abstract: A transporting apparatus for moving away injection-molded articles from an injection molding machine includes pallets; a charging station for loading the pallets; transporting pallets each individually supporting at least one pallet and coupled thereto for forming a transporting unit; a pallet tower spaced from the charging station for storing a plurality of pallets; an elevator for receiving empty pallets from the pallet tower and loaded pallets from the charging station and being vertically freely movable during loading of the pallets in the charging station; a conveyor for moving the transporting pallets between the elevator and the charging station for transferring empty pallets from the elevator to the charging station and for transferring loaded pallets from the charging station to the elevator; and a positioning arrangement for placing the elevator into such a position during transfer thereto of empty pallets from the pallet tower and transfer therefrom of loaded pallets into the pallet tower that a tr

Abstract: Green concrete products, such as building products, are placed on pallets. Those pallets are transported to a kiln for curing and from the kiln after cure by an overhead crane. Pallets are lowered into and removed from open top kilns layer by layer being supported by movable support ledges, for example rotatable toggles, at each layer position which permit vertical entry and removal of the pallet layers. Three kiln compartments permit continuous production, one being filled, one being emptied and the third curing a load of pallet layers.

Abstract: A moulding pallet for moulding building blocks with interlocking surfaces comprises a metal sheet bent to form parallel ridges and valleys, with transverse sheet metal channels inserted through openings in the ridge sides forming transverse secondary ridges.

Abstract: Apparatus for propelling a succession of pallets in a longitudinal direction has a plurality of pawls for pushing the pallets and spaced apart on a pair of endless drive chains each having a portion extending parallel to a pallet guide means. Each pawl is arranged to move in such a way that in use it engages one of the pallets to push it along the guide means and disengages from the pallet further down the guide means, the movement of each pawl being controlled by an associated cam follower wheel cooperating with one of a pair of longitudinally extending cam tracks. The cam follower wheel can be laterally moved on a shaft to select the appropriate cam track for the type of pallets to be conveyed, so that the apparatus can be easily adapted to e.g. different length pallets.

Abstract: Apparatus for precasting concrete products wherein dry mix is deposited in casting cavities defined by mating upper and base form sections, vibrated and/or pressure compacted, and the upper form section removed immediately for curing of a free standing green cast product. A single upper form section cooperates with a number of base sections and the latter are used to transport the green cast products for curing. Automatically separable base section parts are also employed for the transport of cured products. Forms are adapted for fork lift handling and include high intensity vibrators, sight openings for ascertaining a cavity full condition, closure plates for fill openings, pressure applying and finishing devices, and sectionalized construction for various size products. Casting machine includes mix delivery apparatus and form handling apparatus for upper and base form sections for automated casting and transfer of green cast products for curing.

Abstract: This disclosure relates to an apparatus or machine which is especially useful in performing an important article handling function in a semi-automatic production arrangement for inverting and moving interlocking, epoxy bonded blocks. These blocks, commonly referred to as Super Blocks, are cast three at a time on a special steel pallet having accurately positioned cavities. During the casting process eight alignment pins or protrusions are formed on the bottom of each block while at the same time matching alignment dimples or depressions are formed on the top of each block. The semi-cured blocks are inverted by the disclosed apparatus to avoid damage to the alignment pins when the blocks are placed on an exit conveyor. The same block inversion or transfer operation conveniently strips the three blocks off of each of the steel pallets making them ready for the next casting cycle.

Abstract: A supporting ring for casting machines for concrete pipes for use in moulding the socket end of the pipe and as a base for the green pipe during the removal of the casting mould and the initial hardening of the concrete, said ring consisting of a hollow annular body of a closed, preferably substantially rectangular cross-section.
