Abstract: A method is disclosed for the semi-continuous melting of ceramic material by means of inductive melting in high-frequency and medium-frequency induction melting furnaces whose melting coil surrounds a sintering crust crucible and contains a run-out channel. In the method, melt is periodically run out and material to be melted is supplied to the crucible so as to replace the material removed preferably so as to maintain a constant level. An intensively cooled channel is used as a run-out device. For the melt broaching, the melt nose is grasped from below by way of an automatically controllable broaching lance of a broaching device and raised. The broaching lance is then advanced between the bottom of the channel and the solidified melt until the sintering crust is pierced. The method permits a reliable and economic management of the process and the maintenance of the quality of the melted products.

Abstract: There is provided a plunger position detector for detecting a linear position of a plunger used for forming a parison over the entire range of moving of the plunger. Since there is correlation between the plunger position and the gob weight, the gob weight can be detected in response to an output signal of this detector and, in accordance with this detection, a gob forming operation is controlled to an optimum state so that the gob weight will become a predetermined weight. Since difference in center positions between a blank mold for forming a parison and the plunger causes variation in the state of movement of the plunger, this difference in the center positions can be detected in response to a plunger position detection signal and, in accordance with this detection, an optimum registering of the center positions can be performed.

The prefinished parison is transferred to a third, finishing mold, and, at a frequency in a ratio of from 1:1 to 1:4 of the predetermined frequency, the finished glass container is formed. The expansion of the prefinished parison is controlled by the action of compressed air conveyed to the interior of the parison from its mouth.

Abstract: In apparatus for molding glass into hollow-shaped articles such as glass containers, glass charges are delivered to a parison mold wherein the glass is shaped either by a plunger or by a counterblow within the parison mold. The charge of glass that is delivered to the parison mold is guided into the mold by a superimposed funnel.

The mechanism for moving the funnel on a conventional I.S. machine must be capable of moving the funnel from an upper, radially displaced position, to a lower, seated position concentric with the mold. The operation of the funnel seating motion is accomplished by the use of a generally reciprocable, fluid-operated motor in which a funnel-carrying arm is fixed to the piston rod of the motor and the rod is turned about its vertical axis during its upward and downward movement.
