Lightly loaded attachments

Lightly Loaded Attachments A lightly loaded attachment is one where the weld stress due to mechanical loads is not over 25% of the allowable stress for fillet welds and the temperature difference between the shell and attached member is not more than 14° C (25° F). 

Despite the success with gel-phase NMR spectroscopy the spectra obtained are of limited value because of the broad peaks, and indeed the NMR spectra of unlabelled samples need relatively long acquisition times (because of the low abundance of C) especially with lightly loaded resins such as TentaGel and Argo-Gel. NMR [206, 207] and NMR [208, 209] spectroscopy of gel beads have also been shown to be a convenient NMR technique for monitoring reactions of fluorine or phosphorous-containing molecules, respectively, attached to solvent-swollen polymer supports. 

Snap-fit assemblies are usually employed to attach lids or covers that are meant to be disassembled or that wiU be lightly loaded. The design should be such that, after the assembly, the joint will return to a stress-free condition. Materials with good recovery characteristics are required. 

Major Attachments Any part that is not a minor attachment or lightly loaded by definition. 

Lances are paper tubes, generally thin and of light construction, say, to % inch in diameter and 2 to inches long, filled with colored fire composition, loaded by tamping, not by ramming, and are used in set pieces, attached to wooden frameworks, to outline the figure of a temple or palace, to represent a...
