307, Electrical Transmission or Interconnection Systems,

9.1+, for vehicle mounted electrical systems, and subclass 145 for electrical systems which include current collecting or transferring means.

310, Electrical Generator or Motor Structure,

71, for dynamoelectric devices having circuit supply connections therefor. 333, Wave Transmission Lines and Networks,

24+, for coupling networks including significant reactive structure for effecting a transfer of oscillatory energy from one circuit to another circuit and having attenuation and/or delay characteristics over a frequency range for attenuating and/or delaying in a predetermined manner wave energy passing therethrough, and/or providing an impedance match between the network and at least one of the circuits, and subclasses 1+ for such coupling networks in plural channel systems.
