Sectional views, drawing

A still different approach to multilayer adsorption considers that there is a potential field at the surface of a solid into which adsorbate molecules fall. The adsorbed layer thus resembles the atmosphere of a planet—it is most compressed at the surface of the solid and decreases in density outward. The general idea is quite old, but was first formalized by Polanyi in about 1914—see Brunauer [34]. As illustrated in Fig. XVII-12, one can draw surfaces of equipo-tential that appear as lines in a cross-sectional view of the surface region. The space between each set of equipotential surfaces corresponds to a definite volume, and there will thus be a relationship between potential U and volume 0. 

FIG. 18-132 Sectional view of the Cuno Flo-Klean backwashing edge filter. Fluid pumped through the nozzle loosens solids from the filter surface and clears the filtering area. The pump draws filtered fluid from the filter discharge and returns it to the system through the nozzle. Thus, there is no loss of backwash fluid. (Cuno Division, AMF, Inc.)... 

EIektronbombe (Electron Bomb). An incendiary bomb invented in Germany in 1917, but not used until WWII. Its description is given in Vol 2 of Encycl on pp B234 to B237 and on p B235 is a drawing and cross-sectional view.

Figure 4.22 (top and bottom drawings) shows soak zone side-sectional views with T-sensor and burner locations (original and recommended). The two middle drawings show temperature profiles at three soak zone firing rates, plus heat consumption rates for losses, for cold air infiltration, and for heating the loads. The sum of these is the heat flux, which corresponds to available heat. 

Rg. 6.5. Sectional view of a rotary hearth furnace (such as fig. 1.8) with enhanced heating. This also could be a car-hearth batch furnace or in-and-out batch-box furnace. In many cases, the higher velocity burners would be smaller (relative to the main burners above) than they appear in this drawing. In other than rotary hearth furnaces, the high-velocity burners should fire between piers and opposite the main burners—to further enhance circulation. 

Ha -tectimud views are used for symmetrical objects. For such objects, it is customary to draw half of the objea in sectional view and the other half as exterior view. The main advantage of half-sectional views is that they show the interior and exterior of the objea using one view. An example of a half-section view is shown in Figure 16.15. 

For Problems 16.11 throu 16.15, use the cutting planes shoum to draw the sectional views. 

This is the most frequently used method of presenting information on a detail drawing. It is usually the simplest and quickest way of giving an accurate representation, and dimensioning is straightforward. It is only necessary to draw those views that are essential and it is simple to include sections and hidden detail.

Fig. 58. Cross sectional view of the agitation column. The material is "Altuglas MZD" throughout except for the brass screws. The diffuser plate has a total of 213 holes drilled on 8 concentric circles. The inside dimensions of the column are 8.0 cm diameter by 60 cm high. The reader is referred to the original paper for a more detailed drawing.

Multilayer stack-up, defined in Sec. 13.2.2 and Chap. 27, must be carefully specified. This is the function of the stack-up definition (see Figs. 13.9,27.1, and 27.2), which is usually part of the fabrication drawing. Impedance specifications (from the electrical performance data block) should be compatible with the materials stack-up. Figure 20.5 shows a cross-sectional view of the finished multilayer. Figure 20.6 shows the stack-up code.
