Abstract: An imitation tree is made by forming a trunk, roots, branches and leaves by using chiefly stranded wires as a material imitating a natural tree. The stranded wire which is a material may be a composite stranded wire obtained by stranding metal filaments and an optical fiber together, or may be obtained by stranding the same or different kinds of metal filaments selected from iron or an iron alloy, copper or a copper alloy, aluminum or an aluminum alloy and noble metals. The stranded wires are suitably subjected to the annealing or surface treatment such as coloring, plating, lustering, delustering or application of a fluorescent coating material. The stranded wires are bundled together to form a trunk, roots and branches, and the ends thereof are unstranded to form twigs, leaves, buds and blossoms.

Abstract: A factory barge for manufacturing reinforced concrete products comprises a batcher plant mounted at one end of the hull for preparing ready mixed concrete, a reinforced concrete product unloader mounted at the opposite end of the hull, and, between the batcher plant and the unloader, in the order mentioned, concrete placers for receiving the concrete from the batcher plant and placing it into elongated molds held in the fore-and-aft direction, compactors for compacting the concrete in the molds, a curer for curing the concrete compacted in the molds, and a mold remover for removing the molds from the cured concrete products. An equipment for fabricating reinforcement cylinders is mounted on a deck above the deck where the concrete placers are installed, and means for transferring the molds from the concrete placers to the compactors, curer, and mold remover is so disposed as to handle the molds while maintaining them in the fore-and-aft direction.
