Abstract: | Among the algebraic ruled surfaces a theorem ofH. Brauner characterizes certain helicoids of projective screw motions by the property to possess continuous sets of plane shadow curves. Making use of this theorem all algebraic conoids with a plane striction curve are determined in euclidean 3-space and some properties of these curves are discussed. |
