Abstract: Systems, apparatus, and methods for adjusting limb placement in an archery bow are provided. The limb may be adjusted laterally and may be rotated around its length to manipulate the position of the distal end of the limb with respect to the riser. The limb may be rotated by posts extending from the limb or limb bolt. The limb may also be rotated by posts or shims positioned in an adjustable dowel installed in the riser or by shims installed in the limb between the limb and the riser.

Abstract: Small amounts of one or more alkali or alkaline earth metal salts, particularly lithium or calcium salts, added to polytrimethylene terephthalate (PTT) have been found to greatly accelerate the crystallization rate of the polymer. Preferably, from about 1 to about 10 ppm of the alkali or alkaline earth metal, based on metal, is effective. For example, 7 ppm of Li+ can produce about 5-20 times faster crystallization, depending on the rate of cooling, compared to PTT without lithium. The rapid-crystallizing PTT compositions are preferably comprised of carboxylate salt endgroups, COOM, wherein M is an alkali or alkaline earth metal cation, preferably lithium or calcium cation. The metal salt is conveniently added to the polymerization process.
