Title: Horizontal continuous casting of metals
Inventor: FISCHER ALEXANDER J
IPC: B22D11/00
Filed: 2004-12-10
Abstract: A mould for horizontal casting of molten metal comprising a mould body forming an open-ended mould cavity having an inlet end and an outlet end. An annular permeable wall member is mounted in the mould body adjacent the inlet end of the mould cavity with an inner face thereof forming an interior face of the mould. A refractory transition plate is mounted at the inlet end of the mould cavity, this transition plate providing a mould inlet opening having a cross-section less than that of the mould cavity. This provides an annular shoulder at the inlet end of the cavity. Means are provided for feeding molten aluminum through the inlet opening. Separate conduits are also provided for feeding a gas into the shoulder and via the permeable wall means for providing a layer of gas between the metal and the inner face of the mould.

Filed: 2007-06-28
Abstract: Multi-pane glazing units have their internal cavity vented to atmosphere by way of one or more venting apertures that are plugged by porous 'breathing' plugs of predetermined permeativity, to permit controlled equalization of cavity pressure with the atmosphere.  The provision of two such apertures permits the admission of a flow of demoisturizing air or other gas, to de-mist the glazing unit. The plugs permit the outward transfer of moisture from the unit cavity, and may control the rate of cavity pressure change.   The outer glazing pane may be thicker than the inner pane, to better withstand wind gusts.  The venting apertures may be through the glass or the unit peripheral seal.
