Section views

The Ihree principal projection planes of orthographic projection can be thought of os planes of a glass box. 

The views of an object are projected onto the projection planes that are opened into the plane of the drawing surface. 

The outlines of the planes are omitted. The fold lines are drawn and labeled.

The system should support all the inspection types available in the PSP-3 P-scan, T-scan and Through Transmission, TOFD and A-scan. It should be possible to record data for all the inspection types simultaneously. The developments in computer hardware, in particular disk storage, during the last years have made it feasable to increase the emphasis on the A-scan recording modes. It has also been feasible to extend the P-scan format to include P-scan image storage in a full 3D format, that allows cross-section views to be generated off-line. 

The analyze mode display is similar to the scan mode display used online. Analyze mode includes functions for evaluation of data, e. g. markers, measure functions, zoom function and selection of cross-section views. In addition, A-scan data can be reconstructed into images and displayed. 

A section view at defect height permits a detailed analysis. Printouts of the front panels are made by clicking.

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. 

Figure 7.14a illustrates the insertion of a propylene monomer into an edge vacancy in a crystal adjacent to an alkylated titanium atom. In Fig. 7.14b a cross-sectional view of the same site shows how the preferential orientation of the coordinated monomer is dictated by constraints imposed by the protuberances on the crystal surface.

A cross-sectional view of hemp fiber is shown in Figure 3b. It has a Z twist in contrast to the S twist of flax. Hemp is regarded as a substitute for flax in yam and twine. Its eadier use in ropes has been replaced by leaf and synthetic fibers. Hemp fiber is used in Japan, China, CIS, and Italy to make specialty papers, including cigarette paper, but bleaching is difficult. The fiber is coarser and has less flexibiUty than flax. 

A cross-sectional view of kenaf is shown in Figure 3d. The ultimate cells are nearly cylindrical with thick cell walls. Kenaf fibers are shorter and coarser than those of jute. Both chemical (kraft) and mechanical pulps have been produced from kenaf, and successful demonstration mns of newsprint have been made for the Dallas Morning Nem, the St. Petersburg Times, and the Bakersfield Californian with a furnish of 82% kenaf chemithermomechanical pulp and 18% softwood kraft pulp. Kenaf fiber is also considered a substitute for jute and used in sacking, rope, twine, bags, and as papermaking pulp in India, Thailand, and the former Yugoslavia. RoseUe bleached pulp is marketed in Thailand. 

In the Philippines, the principal suppHer of abaca fiber, the fibrous layer ia the sheath is separated with a knife between the layers, and the strips of fiber-containing layers, called tuxies, are pulled off and cleaned by hand to remove the pulp. In Indonesia and Central America these operations are performed mechanically. Hand- and spiadle-stripped fiber is graded for braids, fine textiles, and cordage decorticated fiber is another class. A cross-sectional view is shown ia Figure 4a. The abaca fiber has a large lumen and the presence of siUcified plates is not unusual.
