Title: Improvements in assemblies including elements having anisotropic expansions
Inventor: ROCHE ROLAND
IPC: G21C5/08
Filed: 1958-05-15
Abstract: 889,388. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 15, 1958 [May 17, 1957], No. 15676/58. Class 39(4) A method of assembling a moderator structure so that anisotropic Wigner growth or thermal expansion do not alter the play between moderator elements and their assembly members involves making the members in the form of cylinders with hyperbolic or elliptical cross-sections, the axes of each hyperbola or ellipse being at 45 degrees to the main axes of growth of the moderator elements. Extruded graphite bars are laid so that the directions of extrusion (shown by parallel lines) in adjacent layers are perpendicular; each bar is connected to the layer below near its centre and at one end. One form of assembly member 4, Figs. 6 and 7, has faces of rectangular hyperbolic cross-section, their housings being cut so that the asymptotes are parallel to the directions of extrusion of the bars; gaps are left for expansion along the asymptotes. The axis of extrusion of the member is parallel to that of one of the bars. This form of member prevents relative rotation of the bars. Figs. 9 and 11 show a member of elliptical crosssection with the axes at 45 degrees to its direction of extrusion, which is perpendicular to that of the housing bar 14; integral with the elliptical part is a circular cylinder 16 whose direction of extrusion is parallel to that of its bar 15. Yet another form of member (not shown) is a rectangular slab at 45 degrees to the axes of extrusion of itself and the moderator elements.

The top plate is turned to bring the trajectory on to the point representing the target, and the angle of elevation is then read on a suitable scale. The apparatus is used also for instructional purposes, particularly in connexion with the trajectories of machine guns. In the construction shown, the transparent plate F, Fig. 3, marked with the trajectory G is pivoted at the gun position B to the plate A, Fig. 2, marked with horizontal lines C, D representing heights and arcs E representing ranges. The gun-level line C is graduated in angles of elevation of the gun. In use, the plate F is turned until the trajectory passes through the lines representing the height and range of the target, and the angle of elevation is read on the line C at the point where it is intersected by the trajectory. For use when the angle is small, a second line J, parallel to and below the line C and graduated in positive and negative angles, is provided. Besides the trajectory G, the plate F is marked with trajectories G<1>, G<2> representing the probable upper and lower limits of the cone of fire, and with a curve H defining the safety zone.
