This invention relates to a high throughput glass fiber production system and process to provide optimum glass delivery to the glass fiberizing bushing and enhanced glass production of textile fibers or filaments of glass. The fiberizing system includes dual melters which feed the molten glass through various screens within a high throughput feed bushing positioned below the melters to reduce seeds and condition the glass. The feed bushing directs the molten glass into a dual flow diverter for supplying the molten glass into the optimum location of the glass fiberizing bushings placed below the dual flow diverter.

High throughput glass fiberizing system and process

An interface selector connecting a plurality of field digital devices to a single digital receiving device is disclosed. The interface selector provides a means for the digital receiving device to select which field digital device is to transmit valid data. Circuitry is provided to disable all other field digital devices. Signal lines are provided for the digital receiving device to verify that only one field digital device is transmitting data. Circuitry is also provided to prevent transmission of data if all field digital devices are selected simultaneously.

Digital interface selector

A feeder for delivering streams of molten mineral material for attenuation into filaments having an electrically conductive bottom wall with orifices formed therein. The molten material in the feeder passes through the orifices and is delivered as streams for attenuation into fibers. Extending from the bottom wall, in a direction generally normal to the plane of the bottom wall, are electrically conductive side and end walls. Positioned within the feeder generally parallel to the plane of the bottom wall is a molten material conditioning means. On the exterior surface of each of the end walls there is a terminal for conducting electrical energy to the feeder to heat the walls and molten material conditioning means of the feeder and thereby condition the molten material in the feeder. Each of the terminals has an inner portion attached to the end walls at the location of the molten material conditioning means. The inner member is positioned so that it is generally parallel to the plane of the bottom wall. Each of the terminals also has an outer portion, that is attached to the inner portion, in spaced apart relationship from the end walls. And the outer portion extends from the inner portion towards the bottom wall in a direction generally normal to the plane of the inner member.
