    The author studies the set \(H\) of translates of a fixed helix \(h\) of \(R^3\). He is looking for sets \(F \subset H\) with the following properties: (1) the members of \(F\) are pairwise disjoint, and (2) for all possible translations of \(F\) by vectors \(v\) orthogonal to the axis of \(h\): \((F+v) \cap F=\varnothing\). Applying a combination of methods from set theory and descriptive geometry the author finally demonstrates, that there are more than \(2^{\aleph_0}\) families \(F \subset H\) with the properties (1) and (2) for which \(R^3 = \bigcup F\) holds.
