Abstract: A bow sight apparatus is described with at least one lighted reticle aiming spot which is projected onto a partially reflecting mirror through which the target is viewed to superimpose the aiming spot on the target image. A light guide of fluorescent plastic is employed to convert ambient visible light entering such light guide into colored light of a selected wavelength, such as green light, which is transmitted through one or more aiming apertures in a reticle member to produce the aiming spot. Range adjustment is provided by moving a reticle projection mirror to adjust the position of the aiming spot between different precalibrated range positions, or by providing several different aiming spots corresponding to different target ranges. A bow mount attaches the sight to a bow handle by a bracket which adjusts the sight vertically and horizontally for calibration sighting of the sight.

Abstract: An apparatus and method of cold finishing of metals wherein a metal workpiece having a repeating cross section is advanced between a plurality of pairs of rollers and is driven through a die or cutting tool. The apparatus includes entry vee guides, a gimbaled die or cutting toolholder, special dies, and a special exit guide. The method results in bars having the usual cold finished qualities of accurate size, smooth surface finish, and uniform shape with the added quality of uniform residual stresses.
