Pronouns and procedural meaning: The relevance of spaghetti code and paranoid delusion

A traction drive system for a vehicle is disclosed which comprises a pair of series wound motors (32,34) which are connected in series with each other and which drive independent traction wheels (22,24), respectively, of the vehicle. The no-load torque of each traction wheel is correlated with the transient torque characteristic of the motors so that each motor produces a transient driving torque greater than the threshold-load torque of the wheels. Further, the no-load torque of each wheel is great enough so that the transient driving torque will not fall below the threshold-load torque during a predetermined time interval. This arrangement permits one traction wheel to move the vehicle at low speed while the other traction wheel spins on ice or otherwise fails to exhibit tractive effort.
