Method for sampling molten glass from beneath the surface of a melt (11) comprises sucking it through a glass or ceramic tube (20). This is surrounded by concentric, cooled metal tubes (30, 40). An Independent claim is included for apparatus for carrying out the method in which the glass...
A plurality of stacked container means are positioned about the rod. These container means contain the desired addition agents. The molten metal is then teemed into the ladle and the container means and addition agents are consumed thereby.
[14 Nov 1972] 51104/73 Heading C7D Metal-containing particles having magnetic characteristics are incorporated in molten metal streams by subjecting the stream to a magnetic field in the area where the charge is added in order to force the particles beneath the surface of the stream and aid ...

A ladle for receiving molten metal is equipped with an elongated, refractory lined rod having an enlarged bottom portion and terminating at the lower end of the ladle. A plurality of stacked container means are positioned about the rod. These container means contain the desired addition agents. ...
(84) is disposed beneath the surface; a mechanism (24) for feeding the wire (20) through the nozzle (60) directly into the molten material; and a system (31, 33, 42) for injecting a substantially inert gaseous medium into the molten material together with the wire (20), whereby the ...
