Abstract

112,681. Christie, M. A., (Christic, R. A.). Feb. 1, 1917. Scale rules particularly adapted for artillery calculations. A disk a is-provided with a range scale f and an ''inclined angle " scale e, that is, the angle formed by the lines joining the observer with the target and the base. The central disk c has a base scale g and an " apex angle " scale h, that is the angle subtended by the base from the target. A cursor d of sector shape is pivoted on the centre.
