Abstract: PROCESS     Abstract of the Disclosure Exhaust gases from two-stroke (two-cycle) internal combustion engines which contain relatively high concentrations of carbon monoxide and hydrocarbon are catalytically treated to purify the exhaust gases and thus decrease pollution of the atmosphere.  The catalytic treatment is conducted such that the relatively high concentrations of carbon monoxide and hydro-carbon in the exhaust gases can be reduced without deleteriously affecting the catalyst.  The exhaust gases are passed to a first catalyst zone which contains insufficient catalyst for complete combustion of the carbon monoxide and hydrocarbon, and the first catalyst zone does not reach temperatures which are deleterious to the catalyst.  The effluent from the first catalyst zone contains combustible values and is cooled and passed to a second catalyst zone, said cooling being sufficient to avoid reaching temperatures in the second catalyst zone which are deleterious to the catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE        In the induced repulsion type magnetic suspension railway, superconductive magnets of opposite polarities are alternately set at specific intervals in the longitudinal direction of vehicle, while in the longitudinal direction of track conductive loop coils or con-ductive sheets are continuously set at specific intervals, whereby the repulsion taking place between the eddy current due to a vol-tage induced in said conductive loop coils or conductive sheets by said superconductive magnets and said superconductive magnets levi-tates the vehicle.  In such a railway, an additional source to pro-duce a magnetic field of same polarity is provided on the vehicle; and thereby a magnetic flux with the same period as the vehicle vi-bration is applied intersecting said conductive loop coils or cond-uctive sheets on the ground when the vehicle vibrates.  Thus an in-duced current is produced by said magnetic flux and, using the mag-netic force developed between this induced current and said magnetic source of same polarity, the vibration of a running vehicle can be damped.
