摘要： A process and apparatus for purifying water-insoluble particles is disclosed. The process comprises the steps of continuously recirculating a fluid aqueous suspension of the water-insoluble particles between a filtration system and a suspension reservoir; continuously conducting ultrafiltration of the recirculating suspension at the filtration system to separate an aqueous permeate containing the water-soluble impurities from the recirculating fluid aqueous suspension; continuously discharging the permeate generated by ultrafiltration; adding water to the recirculating fluid aqueous suspension undergoing ultrafiltration at approximately the same volumetric rate per hour as permeate is being discharged; monitoring the purity of the recirculating fluid aqueous suspension; and recovering the purified fluid aqueous suspension after the recirculating fluid aqueous suspension has reached a predetermined purity condition. An apparatus is also disclosed for carrying out the above process. Preferred water-insoluble particles may include lakes (particles with absorbed dye) and particles used to make lakes such as finely divided aluminum hydrate. Advantages of this invention include the ability to consistently produce high purity water-insoluble particles at low cost and with savings in manual labor. Purification according to this invention requires substantially less water than prior art methods, reducing purified water consumption and waste product disposal costs.

摘要： An apparatus and method for locking a focus position of a lens assembly without causing the lens cell to tilt, comprising: a spacer interposed between the lens cell and the focus mount. The spacer is received into a sleeve that is integral with the focus mount. The sleeve projects radially outward from the focus mount such that the spacer can be raised and lowered radially with respect to the focus mount. The spacer has a cylindrical body with a radial flange at one end. Moreover, the spacer has two ridges that extend downward from a lower surface of the flange, each of which is received into a corresponding groove on the sleeve, thus, preventing the spacer from rotating within the sleeve. The spacer also has an upwardly raised rim extending from an upper surface of the flange. The rim is slidably secured into a slot of the focus mount, which prevents lateral movement of the spacer. Further, a bolt is coupled to an opening within the spacer, such that one end of the bolt is disposed and secured within the spacer and the other end of the bolt extends radially outward through the slot of the focus mount. A nut is secured onto the bolt. After focusing the lens cell assembly, the nut is tightened onto the bolt in order to maintain focus of the lens cell assembly. The tightening of the nut brings an upper surface of the flange of the spacer into frictional engagement with an interior surface of the focus mount, which prevents the tilting of the lens cell within the focus mount, thus, maintaining a focus position of the lens assembly.
摘要翻译：一种用于锁定透镜组件的聚焦位置而不使透镜单元倾斜的装置和方法，包括：插入在透镜单元和聚焦底座之间的间隔件。间隔件被接收到与聚焦装置成一体的套筒中。套筒从聚焦架径向向外突出，使得间隔件能够相对于聚焦座径向升高和降低。间隔件具有在一端具有径向凸缘的圆柱体。此外，间隔件具有从凸缘的下表面向下延伸的两个脊，每个脊被容纳在套筒上的相应凹槽中，因此防止间隔件在套筒内旋转。间隔件还具有从凸缘的上表面延伸的向上凸起的边缘。边缘可滑动地固定到聚焦装置的狭槽中，这防止间隔件的横向移动。此外，螺栓联接到间隔件内的开口，使得螺栓的一端设置并固定在间隔件内，并且螺栓的另一端径向向外延伸穿过聚焦座的槽。螺母固定在螺栓上。在聚焦透镜组件后，将螺母拧紧到螺栓上，以保持透镜组件的聚焦。螺母的紧固使得间隔件的凸缘的上表面与聚焦装置的内表面摩擦接合，这防止透镜单元在聚焦架内的倾斜，从而保持透镜组件的聚焦位置。
