Abstrakt: A spinor representation for the conformal group of the real orthogonal space $ {R^{p,q}}$ is compactified by adjoining a (closed) isotropic cone at infinity. Then the nonlinear conformal transformations are linearized by regarding the conformal group as a factor group of a larger orthogonal group. Finally, the spin covering group of this larger orthogonal group is realized in the Clifford algebra $ {R_{1 + p,q}}$ on the orthogonal space $ {R^{p,q}}$. Explicit formulas for orthogonal transformations, translations, dilatations and special conformal transformations are given in Clifford language.
