Abstract: Curtain wall based drain opening apparatus comprises a drainage element extending outwardly from, and in fluid communication with, a concealed horizontal water flow channel associated with a stationary first frame element of an inwardly pivotable window assembly and adapted to receive infiltrated water, wherein the drainage element passes through a second frame element which is laterally spaced from two adjacent fixed panels of a curtain wall and is exposed to atmospheric air.

Abstract: A method of moulding an object of indefinite length. A first portion of molten material is injected into a mould comprising a stationary platen and a moving platen and solidifies to form a first portion of solid material at a first position. The moving platen is moved in a given direction to open the mould and move the material in said given direction to a second position in communication with the mould. The moving platen is then moved in the opposite direction to close the mould. A further portion of molten material is injected into the mould and solidifies to form a further portion of solid material intimately bonded to said first portion. The steps are repeated to form an object comprising the first portion and further portions of material bonded together as a linear array of indefinite length.
