    摘要： A concentrated mass launcher including a handle a cradle portion having a first anterior wall and a second anterior wall, the first and second anterior walls being opposed to one another and being separated from one another to form a gap, the cradle portion being positioned above the handle; an upper resilient limb extending from the cradle portion; a lower resilient limb extending downwardly from the handle; a string extending from the upper resilient limb toward the lower resilient limb; a sling being disposed about the primary string; a first resilient member being connected at a first end to the sling about a perimeter edge, and being connected to the cradle portion; and a second resilient member being connected at a first end to the sling about the perimeter edge, and being connected to the cradle portion.

    摘要： A laminated archery bow limb has a relatively light weight core consisting of a plurality of hollow micro spheres in a matrix of hard synthetic resin and formed as a tapered strip of "syntactic foam" material with relatively thin facing and backing strips of high tensile and compressive strengths and a high rate of recovery glued to opposite sides thereof. In a second form of bow limb construction the core material further includes, in addition to the hollow micro spheres, reinforcing fibres to increase the physical strength thereof.
