A rectangular parallelepiped ingot defined by a height H, a width W and a length L, having longitudinal faces extending between two end faces, having a volume between 0.15 m.sup.3 and 0.80 m.sup.3 and a surface area to volume ratio between 10 m.sup.−1 and 18 m.sup.−1, made of at least one metal, including at least one notch and a notch tip along the ingot length, wherein the at least one notch is configured such that: MaxD<H/2, MaxD<W/2 and MaxD being the maximum distance between any point of the ingot and the closest surface of the ingot.

A system for casting by splitting molten materials, and more particularly, for casting molten materials received from a furnace into a plurality of unit forms of a predetermined size, including a body unit, forming a main structure of the system, providing a space where the molten materials are received from the furnace; a side packing unit, disposed at the front and rear sides of the body unit, partially covering the body unit.

A metal product manufacturing device is provided to remove, with higher accuracy, impurities from a molten metal of a non-ferrous metal or another metal containing the impurities, obtain the molten metal having higher purity, and obtain a high-purity non-metal product or another metal product from the high-purity molten metal.

Method and installation for converting a metal in the liquid state into a fragmented metal in the solid state. The metal in the liquid state is poured on an upstream portion of a receiving surface (7) of a first cooled vibrating table (4). The metal falls from the downstream end of the first table on an upstream portion of a receiving surface (17) of a second cooled vibrating table (5). The fragmented and solidified metal is discharged at the downstream end of the receiving surface of that second table. A rotary fragmentation roller (102) may be positioned above a table. The tables comprise an upstream cooling zone (7) by means of a liquid/gas emulsion and a downstream cooling zone (17) by means of a liquid.

A gas turbine engine combustion chamber heat shield and seal assembly comprises a heat shield and a seal. The heat shield has an aperture and the seal is located in the aperture in the heat shield. The seal comprises an annular member having an upstream end, a middle and a downstream end. The upstream end of the seal has a diameter greater than the diameter of the aperture in the heat shield, the middle has a diameter less than the diameter of the aperture in the heat shield and the downstream end of the seal has a diameter greater than the diameter of the aperture in the heat shield.
