Metal Threads. Metal threads, not really metal fibers but metal filaments, are human-made. In antiquity, metal threads were made for ornamental or decorative purposes from precious, ductile metals or alloys, particularly silver and gold and their alloys. Such threads were either applied with adhesives to finished fabrics or wound around ordinary textile yam cores the metal-covered yarn was then either woven into textile fabrics or embroidered on the textile fabric (Jaro and Toth 1991 Lee-Whitmann and Skelton 1984). 

The EVOLUTION mechanical dilator sheath set (Cook Vascular) is composed of an inner plastic sheath with a threaded metal tip and an outer telescoping polymer sheath. The inner sheath has a stainless steel tip at its distal end, and no electrical energy supply is required. This sheath is mounted on a pistol capable of mechanically rotating the sheath. Multiple sheath sizes are available 7 F, 9 F, 11 F, and 13 F. A shortle version, with a shorter sheath length, is also available. Although this sheath has the capability of dissecting through all types of tissues, even calcified adhesions, there are only limited experiences reported in literature [20, 21], and some complications related to this tool are described [22] (Fig. 4.13). 

The boss in Fig. 8.19a will not supply the strength necessary for structural applications like threaded metal inserts and self-tapping screws. Structural applications require much stronger boss walls like those (f) in Fig. 8.196. As the circle in the lower left comer illustrates, the 25% maximum wall increase rule is exceeded by a considerable... 

Thermoformed decorative inserts and labels have been molded into cold-press molded parts however, threaded metal inserts cannot be molded-in. Threaded inserts can be glued or tapped in place, but not into bosses, which are impractical. Molded-in holes, core pulls, slides, undercuts, and ribs are, likewise, imfeasible. Holes need to be drilled and their location can be held to 0.030 in. The same assembly methods used for parts made firom compression molding can be used for those made from this process.

Adhesive choice can therefore be influenced by actual joint tolerance control and dimensions and where a cyanoacrylate or an anaerobic adhesive might be ideal (polymeric substrates or a threaded metallic joint, respectively), the measured bond gap may be too large and an alternative adhesive such as a polyurethane or an epoxy may be better suited. 

Unless care is taken in the mounting of the sensor and the choice and attachment of its leads, the sensor will be appreciably warmer than the device we intend to monitor. We need good thermal contact between the thermometer and the object whose temperature is to be measured. This can be achieved by using threaded metal mounts and contacting across a large surface area. 

The chief advantage of threaded metal inserts in a polymer component is the ability for multiple disassembly and assembly of a multicomponent assembly. The obvious...
