The filter structure consists of a stack of plates attached to a hollow shaft which are mounted inside a pressure vessel with each plate covered with a suitable filter medium. The slurry is fed under pressure into the vessel and the cake, which is retained by the filter medium, forms on the top of each plate whilst the filtrate passes through the hollow shaft further to the process. Filter sizes may vary but generally the maximum is 60 m area and designed for a 6 bar operating pressure. Each circular plate in the stack is constructed with radial ribs that are welded to the bottom and support a horizontal coarse mesh screen which is covered with a finer woven metal screen or filter cloth to retain the cake. The bottom of the plate slopes towards the hollow central shaft which lets the filtrate flow freely through circumferential holes and further down the shaft to the filtrate outlet. The clearance between the plates is maintained by special spacers with "o" rings to positively seal between the slurry that surrounds the plates and the shaft that collects the filtrate. The height of the spacers determine the clearance for cake build-up and may be replaced to meet various process conditions. 

Little s superconducting polymer would have long molecules and an atomic structure similar to a skeleton. Two electrons would move down the backbone of the structure at regular intervals they would pass ribs, or chains of complex atomic structures, shoving other electrons out of the way along the ribs. The positive field created by the... 

Researchers at Rib-X Pharmaceuticals, in addition to reaching Phase II with an oxazolidinone, have also capitalized on the structure of available ribosome macrolide complexes [81-84]. Macrolides (Scheme 4) such as azithromycin (1), clarithromycin (10), and telithromycin (Ketek, 12) are positioned near to linezolid in the PTC region, again binding mostly to RNA. The structures of azithromycin (PDB 1M1K, 1YHQ) and linezolid led to a series of compounds that extended the structure of the macrolides in ways medicinal chemistry had previously considered undesirable. 

Figure 8-24 shows some designs of space erectable structures. In each case the gas pressure moves the materials that form the skins and ribs into final position. If the structural material is an unreacted resin plus reinforcement, the structure can be rigidized permanently by curing the resin in place as illustrated in Fig. 8-25. This is done by several methods such as the use of actinic light from the sun with...

Figure 12.5 shows a schematic of the structure of a V-ribbed belt. The most commonly reported mechanical failure mode for this type of belt is wear, with delamination not generally perceived as a problem. This is of interest as most flexible composite elements will have a delamination failure mode of some description, and so the most obvious question to ask is why the V-ribbed belt does not. The probable answer is that the belt cord in a V-ribbed belt is isolated from the major distortions of the belt through its position above the belt/pulley interface. The large majority of the distortion of the belt takes place in the belt ribs, away from the cord. If the four shear stresses identified previously by Gerbert and Fritzson for a V-belt are considered, it can be seen that of the four i) and ii) do not apply to the cord layer in a V-ribbed belt. The cord layer in a V-ribbed belt therefore does not incur shear stress to the same extent as that in a V-belt. Thus the V-ribbed belt may be considered a better design in composite terms, with the individual elements of the composite more effectively employed and protected. 

Evaluation of the clavicle is discussed in Chapter 80 (Evaluation of the Shoulder). Because of the close relationship between the clavicle and the first rib, when first or second rib restriction is found, the clavicle must be evaluated. Its normal position, structure, and motions are all significant to normal functioning of the thoracic cage. 

The occipital atlantal junction was restricted in flexion and extension but symmetric and sidebending in rotation. There was tenderness along the superior nuchal line bilaterally. There was a mild thoracic and lumbar flattening with a decreased excursion of the diaphragm and rib structures on inhalation. The left first rib was restricted with the rib in the elevated position. The thoracolumbar junction was tender to palpation in the midline and bilaterally across the... 

In a flooded lead-acid battery, the sulfuric acid serves as both the electrolyte for conductance of the ions and it also promotes the electrochemical reaction. To achieve optimum performance from a battery, the amount of sulfuric acid should be stoichio-metrically balanced around the other reactants, namely, the positive and negative active material. The amount of electrolyte between electrodes is fixed by the 3D structure of the flooded lead-acid separator. Normally facing the positive electrode, there are ribs protruding off the planar surface of the substrate that serve to fix the distance between the electrodes and thus the volume available for the electrolyte [27]. Figures 4.9 and 4.10 illustrate some typical profiles. 

Structural seams. The purpose of this seam type is to stitch the elements, which transmit the forces between various semi-finished goods or layers via tailored reinforcements e.g., ribs on support structures). These seams can also be used for positioning inserts or to enhance connections of inserts to the entire structure. Joining seams penetrate through the complete preform and are stitched by using threads made of carbon or glass fibers. 

Subsequently, 8-nor-8-hydroxy-flavin compounds were synthetized by an analogous procedure and were shown to simulate the spectral parameters of the natural product at the riboflavin level as, for example, in the ESR (Fig. 3), the pH dependence of fluorescence emission and absorption spectra. Thus the structure of the orange chromophore was established as the 8-nor-8-hydroxy-derivative of FAD (18, R = Rib-( )-AMP). Alternatively, a hydroxy function can be introduced into position 8 of the flavin ring by hydrolysis of 8-nor-8-diazonium-flavin compounds 152).
