Abstract
Abstract Lattice for the giving of sideways support to fissile rods as used in a nuclear reactor, or other rods or pipes, likewise subjected to heat exchanging conditions, as for example in a heat exchanger. The lattice is composed of elongated metal strips, connected at intervals by transversely poised brackets, consisting of narrow strips, of which the connecting edges are bended into lips, set at an angle, to be fixed at the elongated strips.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
A lattice spacer structure for supporting cylindrical heat exchanging elements, said structure comprising: a plurality of elongated parallel flat strips positioned lengthwise and interconnected with brackets thereby forming a plurality of compartments, each of said compartments being defined by a pair of said strips and a pair of said brackets, each of said brackets including a body portion extending the width between said strips having separate bent lip portions on both sides, each lip portion being fastened to one of said strips by spot welds which are spaced-apart along a line parallel to the axis of the compartment and each lip portion having a notch between every two spot welds and an integral curved spacer, said spacers being positioned on one of said brackets to support said cylindrical heat exchanging elements within one of said compartments, and said cylindrical elements also being secured to a second bracket by a plate spring fastened to the back of each of said brackets.
