    • In an apparatus for conditioning a supply of molten thermoplastic material, preferably glass, a chamber in flow communication with the supply of glass is mounted for rotation about an axis. The chamber has a flow control surface having at least two regions, each uniquely oriented for influencing the flow of the molten glass therealong. In one region the glass experiences delayed flow to enable it to give up heat and in a region downstream of the first, the glass experiences accelerated flow to enable it to counteract changes in viscosity resulting from previous heat loss. The chamber is rotated so that a fresh supply of glass at an elevated temperature is deposited circumferentially on the flow control surface in order to moderate the influence of heat loss as the glass flows through the chamber.
    • 在用于调节熔融热塑性材料(优选玻璃)的供应的装置中,安装有与玻璃供应流动连通的室,用于围绕轴线旋转。 腔室具有至少两个区域的流动控制表面,每个区域均独立地定向以影响其中的熔融玻璃的流动。 在一个区域中,玻璃经历延迟的流动以使其放热,并且在第一个区域的下游区域中,玻璃经受加速流动,使其能够抵消由先前的热损失引起的粘度变化。 使腔室旋转,使得在高温下新鲜供应的玻璃在圆周上沉积在流动控制表面上,以便在玻璃流过腔室时缓和热损失的影响。

    • There has been provided a delivery system for conditioning molten thermo-plastic material, wherein a first pipe member, having an inlet at one end adapted to receive the material and an outlet at an opposite end for delivering the material therefrom at a desired homogeneity is coupled at its inlet end to a furnace. An insulated shell structure, having at least one fluid inlet and outlet therein, is located concentrically about the first pipe member and defines a closed insulated space thereabout. The shell is adapted to receive heat exchange fluid for circulation from the inlet to the outlet in said closed space for removing heat from the thermo-plastic material flowing through the pipe member. Means is provided for shielding inside surfaces of space between the shell and the pipe member from deleterious ambient including a purge fluid which may act alone as the heat exchange fluid.
    • 已经提供了一种用于调节熔融热塑性材料的输送系统,其中在一端具有适于容纳材料的入口和在相对端具有以期望均匀性递送材料的出口的第一管件被耦合 在其入口端到炉。 在其中具有至少一个流体入口和出口的绝缘壳结构围绕第一管构件同心地定位并且在其周围形成封闭的绝缘空间。 壳体适于接收用于在所述封闭空间中从入口到出口循环的热交换流体,用于从流经管构件的热塑性材料移除热量。 提供了用于屏蔽外壳和管构件之间的空间的内表面的有害环境的装置,包括可单独作为热交换流体的吹扫流体。
