Abstract: An elevation assembly for an archery sight includes a rail adapted for connection with a bow and having a plurality of spaced teeth extending from a surface thereof. An elevation block is mounted on the rail for reciprocal sliding movement between the ends of the rail. A pinion wheel is connected with the elevation block. The wheel includes a plurality of teeth which are configured to mesh with the pinion teeth of the rail. A knob is connected with the pinion wheel. Rotation of the knob rotates the pinion wheel to displace the wheel and the elevation block along the longitudinal axis of the rail for precise elevation adjustment of the archery sight. Pressing the knob along an axis normal to the rail longitudinal axis moves the pinion wheel along the normal axis away from the rail axis to disengage the pinion wheel teeth from the rail teeth and allow the elevation block to slide freely along the rail for quick course elevation adjustment of the sight.

Abstract: A series of nominally identical production workpieces are measured on a workshop coordinate measuring apparatus. They are corrected using correction values generated by comparing coordinate values of a reference workpiece measured on the workshop apparatus with corresponding values derived from external measurements. To reduce the care and skill required, the external measurements are used to determine reference values of a geometric property of a feature of the reference workpiece, rather than coordinate values corresponding directly to those made on the workshop apparatus. Corresponding coordinate values are then generated from knowledge of the perfect form of the feature of the reference workpiece.
