Atomarer Aufbau kristalliner Stoffe, are proposed. In the first model (for leptons), based on SU(3) × U(1) symmetry, it is shown how this symmetry could be reduced to U(2) × U(l) for weak interactions by virtue of the chiral projectors. The lepton self-masses can be made infra-red driven and/or small by the internal algebra. In the se
