摘要： In apparatus for the straight-line shearing of molten glass gobs, first and second carriage members have mounted thereon one or more opposing pairs of shear blades which are caused reciprocally to move towards each other and then away from each other along a substantially straight line between an open position and a closed cutting position. The carriage members are slidably mounted on wayrods and are connected to diametrically opposed crank arms extending from a rotatably driven shaft. As the shaft is caused to rotate, the carriage members reciprocally slide on the wayrods between the open and closed positions.

摘要： Forehearths for use in glass production comprise a refractory trough (52) for molten glass with an insulating roof thereover, means for heating glass in the trough and means for blowing cooling air across the inside of the roof surface; the forehearth being constructed of at least two sections (A, B and C) which have different insulating characteristics from each other. Preferably the forehearth roof is made up of prefabricated block members of refractory material lying side by side and each of which member spans across the trough. Different insulation is provided over the prefabricated block members to provide different insulating characteristics within sections of the forehearth. The invention also provides prefabricated members for use in the construction of the forehearth according to the present invention.

摘要： An abrasive sheet member is disclosed, including a substrate having first and second major surfaces, an abrasive on the first major surface, and a plurality of hooking stems on the second major surface. The hooking stems are adapted to hook engaging structures on an opposed surface to releasably affix the abrasive sheet member to the surface.

摘要： An electrically heated forehearth for use in glass production is heated by means of a plurality of radiant heating elements, each element traversing the forehearth substantially at right angles to the direction of glass flow and each element comprising heating zones at each edge portion and a central, non-heating zone. With the forehearth according to the present invention the molten glass is heated electrically at its edge, cooler, portions only. The central and therefore hotter part of the molten glass under the non-heating zone of the element is unheated.
