摘要： A method for eliminating or controlling electroosmosis and other zeta potential related phenomena in electrophoresis comprising conducting electrophoresis employing electrophoretic surfaces coated with covalently bound hydrophilic, neutral polymers is described. An electrophoretic chamber for eliminating or controlling electroosmosis and other zeta potential related phenomena in electrophoresis comprising electrophoretic surfaces coated with covalently bound hydrophilic, neutral polymers, is also disclosed as well as particles exhibiting controlled electrophoretic mobility. The method and electrophoretic chamber not only eliminate electroosmosis, but allow for specific control of electroosmosis. The coated electrophoretic surface is stable relative to prior art coatings and over a broad range of pH. The point of optical focus for accurate mobility measurements is increased from a narrow stationary level to the entire chamber, facilitating accurate measurements by mechanical means. The method also reduces or eliminates assymetric fluid flows due to electroosmosis in electrophoresis chambers of square or rectangular cross-section.
摘要翻译：描述了消除或控制电泳中的电渗和其他ζ电位相关现象的方法，包括使用涂覆有共价结合的亲水性中性聚合物的电泳表面进行电泳。还公开了一种用于消除或控制电泳中电渗和其它ζ电位相关现象的电泳室，其包括用共价结合的亲水性中性聚合物涂覆的电泳表面，以及显示受控电泳迁移率的颗粒。该方法和电泳室不仅消除了电渗，而且允许特定的电渗控制。涂覆的电泳表面相对于现有技术的涂层和宽泛的pH值是稳定的。精确移动性测量的光学焦点从狭窄的静止水平增加到整个腔室，有助于通过机械手段进行精确的测量。该方法还减少或消除由于正方形或矩形横截面的电泳室中的电渗而导致的不对称流体流动。

摘要： A compact disc storage book is formed with board book pages having pockets therein to receive compact discs. The board book is comprised of folded, printed signatures adhered to one another. A hard cover is attached to and covers the pages to protect the pages and compact discs from damage or contamination. The board book has an expandable spine, which increases its size or thickness from its smaller empty size to its larger, filled size when filled with compact discs. In the preferred method of making this storage book, the signatures have been printed and slit to form the CD receiving pockets prior to being folded on a signature folding machine. The folded signatures are fed by feeders of a signature gathering machine in proper sequence onto a gathering conveyor. The signature gathering machine has a programmable glue applicator to form the glue pattern including the glue pattern for the accordion fold, expandable backbone for the book form. The outer protective cover is attached, preferably by adhering the outer book form pages to facing sides of the casing cover.
摘要翻译：一个光盘存储书形成有具有口袋的板书页以接收光盘。板书由折叠的，印刷的签名组成。硬盖被附着并覆盖页面，以保护页面和光盘免受损坏或污染。板书有一个可扩展的脊椎，当其装满光盘时，它可以将其尺寸或厚度从较小的空白尺寸增加到更大的填充尺寸。在制作这种存储书的优选方法中，已经打印签名并在折叠在签名折叠机上之前将其切割以形成CD接收口袋。折叠的签名由签名收集机的馈送器以适当的顺序进给到收集输送机上。签名收集机具有可编程胶水涂布器，以形成包括用于手风琴折叠的胶合图案的胶水图案，用于书本形式的可扩展骨架。优选地，通过将外部书本页面附着到壳体盖的相对侧面来附接外部保护盖。

摘要： A cable system comprises a main line carrying first RF signals for a plurality of subscribers, and a subscriber line coupled with the main line and carrying the first RF signals between the subscriber's facility and the main line and also carrying second RF signals that are different in frequency from the first RF signals. The system further comprises a rectifier/voltage multiplier connected to the subscriber line for converting AC energy in the second RF signals into DC current, and an active RF device powered by the DC current from the rectifier/voltage multiplier, the RF device being located along the subscriber line. The system can include a filter connected between the subscriber line and the rectifier/voltage multiplier for filtering the second RF signals. The rectifier/voltage multiplier can be located either inside or outside the subscriber's facility.

摘要： An active step attenuator can attenuate the RF signal from a cable modem or other RF source. The active step attenuator converts the RF energy into a DC control signal that controls the attenuation applied to the RF signal. The voltage of the control signal is proportional to the RF energy, so that the active step attenuator attenuates a stronger RF signal more than a weaker RF signal. The active step attenuator may be in the form of a diplex circuit, one branch of which passes signals in one frequency band without attenuation and the other branch of which actively attenuates signals in another frequency band.
