    摘要: EDI apparatus for demineralizing a liquid flow is assembled in a housing having a cylindrical shape, and includes two metal electrodes, and one or more leafs, each leaf comprising a pair of selectively ion-permeable membranes arranged parallel to each other and spaced apart by spacing elements that allow liquid to flow in the interstitial space between membranes, thus forming an arrangement of dilute and concentrate cells in a desired flow configuration. Spacing elements between membranes, as well as between leaves, can be formed of inert polymer material, ion exchange beads, ion exchange fibers, a combination of two or more these elements, or a porous media incorporating one or more of such elements as an intrinsic part. An inner or central electrode and an outer or perimeter electrode establish a generally uniform and radially-oriented electrical or ionic current between the inner and the outer electrodes, across the helical flow spaces defined by the membrane/spacer windings. One or both electrodes may include a pocket, and the adjacent flow cells lie parallel to the electrode and free of shadowing and field inhomogeneity around a full circumference of the electrode. Flow paths within the helical cells are defined by barrier seals, which may form a path-lengthening maze, while unfilled cell regions may disperse or collect flow within a cell and define pressure gradients promote directional flows. Impermeable barriers between membranes further prevent the feed and concentrate flows from mixing. In various embodiments, seals along or between portions of the flow path may define a multi-stage device, may define separate feed and/or concentrate flows for different stages, and/or may direct the feed and concentrate flows along preferred directions which may be co-current, counter-current or cross-current with respect to each other within the apparatus.

    摘要: A method and an apparatus for liquid safety-detection with a radiation source relate to a radiation detecting technology field. The main steps of the method of the invention are: an article to be detected being conveyed into an operation zone within a radiation shield field; the ray emitted from a radiation source passing through the article to be detected, and being received by a detector; the detector transmitting the received ray signal to a data collector; the data collector amplifying and forming the ray signal, and transmitting such data and the data collected by thickness measuring probing heads to a data processing computer; and the data processing computer processing the two groups of data to derive the density and atomic number of the detected liquid, comparing the result with the densities and atomic numbers of dangerous articles in a existing database, and displaying the detected information of the detected article. Comparing to the prior art, the invention is not subjected to the affection of the outside package of an article and has great anti-interference, and has the features of small volume, high accuracy of detection, easy shielding, and high use safety and reliability.

    摘要: An integrated circuit that performs data demodulation on partially despread symbols includes a despreading unit, a channel compensation unit, and a symbol combiner. The despreading unit despreads input samples and provides despread symbols for a first code channel with a first spreading factor. The channel compensation unit multiplies the despread symbols with channel estimates and provides demodulated symbols. The symbol combiner combines groups of demodulated symbols to obtain recovered data symbols for a second code channel with a second spreading factor that is an integer multiple of the first spreading factor. The channel compensation and symbol combining are dependent on whether or not transmit diversity is used. For a TDM design, despread symbols for multiple first code channels are processed in a TDM manner, one channel at a time, to obtain recovered data symbols for multiple second code channels. The channel compensation unit and symbol combiner can be operated in a pipelined manner.
