    • A cylindrical carrier 1 is covered by a length of rope 3 which is helically close-wound between end cheeks 2a, 2b. A backing plate 4 for attachment to a wall has two support walls 6a and 6b extending from its front face, and the walls have opposed recesses 9 and 10 to receive the end cheeks 2a, 2b. The upper wall 6a receives a pin 12 secured to a knob 13, and the pin is received in a corresponding hole in the upper end cheek 2a. The pin 12 normally prevents the carrier 1 from rotating, but provision is also made for the carrier to be rotated to ensure even wear, and for the carrier to be removed for replacement.
    • 一个圆柱形的托架1被一长度的绳索3覆盖,绳索3在端面2a,2b之间是螺旋紧密缠绕的。 用于附接到壁的背板4具有从其前表面延伸的两个支撑壁6a和6b,并且壁具有相对的凹部9和10以接收端面2a,2b。 上壁6a接收固定在旋钮13上的销钉12,该销被容纳在上端面颊2a中相应的孔中。 销12通常防止托架1旋转,但是也为托架提供转动以确保均匀的磨损,并且为了更换而移除托架。

    • A composite biological-molecule-accretion material (10) is described for extracting desired target biological molecules from aqueous solution (24) and substantially permanently binding to those molecules. The material (10) includes a first component (10a &cir& _) designed with a binding affinity for proteins and peptides in such solution, and a second component (10b &cir& _) designed with a binding affinity for nucleic acids in such solution. The material (10) is capable of being formed in a body (12) for passing such solution through it, and such passing has the effect of removing the proteins, peptides and nucleic acids from such solution and binding them to the body. That binding is substantially permanent so that subsequent passage of additional aqueous solution will not unbind substantially the accreted proteins, peptides and nucleic acids. The first component (10a &cir& _) may include dextran-coated (10a &cir& _2) activated charcoal particles (10a &cir& _1), and the second component may include an anion-exchange resin and a cation-exchange resin. Preferred relative volumes of both components are 1:1. Also described is a method for extracting desired target biological molecules from aqueous solution and substantially permanently binding them to a solid, and a method of filtering target biological molecules out of water.
    • 描述了用于从水溶液(24)中提取期望的目标生物分子并基本上永久地结合这些分子的复合生物分子增加材料(10)。 材料(10)包括设计成对这种溶液中的蛋白质和肽具有结合亲和力的第一组分(10a)和设计成对这种溶液中的核酸具有结合亲和力的第二组分(10b)。 材料(10)能够形成在主体(12)中,以使这种溶液通过它,并且这种通过具有从这种溶液中除去蛋白质,肽和核酸并将它们结合到身体上的作用。 该结合基本上是永久性的,以便随后的另外的水溶液的通过不会基本解除与增生的蛋白质,肽和核酸的结合。 第一组分(10a)可以包括葡聚糖包被的(10a→2)活性炭颗粒(10a→1),第二组分可以包括阴离子交换树脂和阳离子交换树脂。 两种组分的优选相对体积为1:1。 还描述了用于从水溶液中提取期望的目标生物分子并将它们基本上永久地结合到固体上的方法,以及将目标生物分子从水中过滤的方法。
