摘要: An automated system for casting hollow fiber membranes into a variety of prescribed shapes, including spiral, linear, circular and rectangular. The system also has the capability to change the configuration during casting, which increases productivity. A co-extrusion die is rotated over a stationary coagulation bath A computer is used to control the motion of the die to make a membrane with the desired shape The nozzle is oriented in a manner that will compensate for distortions that occur in wall thickness in the area of a bend. In addition, the nozzle's annulus is offset to make the leading portion of the annulus slightly thicker and the trailing portion thinner at the point where the fluids exit the nozzle, which results in a uniformly symmetric wall thickness. A system embodying the invention includes X, Y and .theta.-directional servomotors 1A-1C (FIG. 1), each of which is coupled to an associated position encoder 2A-2C. The motors are controlled by a computer 3 via servodrivers 4 and an associated interface card. Also included in the system are a tub 5 for holding a coagulation bath, bearings 6, carriage 7, screw drive 8, rotary table 9 and co-extrusion die 10.
摘要翻译: 一种用于将中空纤维膜铸造成各种规格形状的自动化系统,包括螺旋,线性,圆形和矩形。 该系统还具有在铸造过程中改变配置的能力,从而提高了生产效率。 共挤出模头在固定的凝固浴上旋转使用计算机来控制模具的运动以制造具有所需形状的膜。喷嘴被定向成能够补偿在壁厚中发生的变形 弯曲区域。 此外,喷嘴的环带被偏移以使得环形物的前导部分稍微更厚,并且尾部部分在流体离开喷嘴的点处更薄,这导致均匀对称的壁厚度。 体现本发明的系统包括X,Y和(θ)方向伺服电动机1A-1C(图1),每个伺服电动机联接到相关联的位置编码器2A-2C。 电动机由计算机3通过伺服驱动器4和相关的接口卡来控制。 系统中还包括用于保持凝固浴的滚筒5,轴承6,滑架7,螺杆驱动器8,旋转台9和共挤出模头10。

摘要: A method of producing printing plates having microdots in nonimaged areas is disclosed. The method includes placing a photocurable polymer composition with oxygen inhibitor characteristics on a backing sheet and spacing an image carrier with a microdot pattern from the polymer composition and applying actinic radiation. The image carrier may additionally contain the printing image.

摘要: A process and apparatus for an electrostatic spray coating operation wherein liquid overspray in the spray coating operation is collected and drained onto a workpiece support. The overspray is then removed from the workpiece support by a squeegee blade wherein the collected overspray is drained into a sump. From the sump, the spray, and optionally with makeup liquid, is recycled to the spray head.
