A rotary internal combustion engine which comprises a housing containing an axle, a pair of toroidal casings both disposed in parallel within the housing, the toroidal casings containing a rotor with a piston disposed within the casings, respectively, an on/off valve in a closed position for forming an ignition and explosion zone with the piston disposed in the casings, respectively, and a gas outlet in the on/off valve disposed in the casings, respectively, whereby the rotary internal combustion engine is achieved by continuously transferring a compressed air-fuel mixture into the ignition and explosion zone, igniting and simultaneously exploding the mixture continuously, and exhausting gases of combustion through the gas outlet in the closed valve position, and thereafter, the piston passes through the valve in an open position thereby causing rotation of the rotors with the axle.

A rotary internal combustion engine which comprises a housing containing an axle, a pair of toroidal casings both containing a rotor with a piston disposed within the respective casings, an on/off valve for forming an ignition and explosion zone together with the piston disposed in the casings, and a gas outlet in the vicinity of the on/off valve disposed in the casings, whereby the rotation of the rotor within the internal combustion engine is achieved by transferring a compressed air-fuel mixture into the ignition and explosion zone, igniting the mixture and simultaneously, exploding, and exhausting the combusted gas through the gas outlet, thereby causing the rotation of the rotors together with the axle.

The present invention provides a method for cleaning fabric articles which comprises the steps of: washing the fabric articles with a cleaning solvent in a rotatable drum; rotating the drum at a high spin speed for a high spin period of time after the performance of said washing step; and heating the fabric articles for at least a period of time during the performance of said rotating step. During the heating step, at least some of the cleaning solvent is removed from the fabric articles in both liquid and vapor phases. Heating the fabric articles decreases attractive forces between the liquid phase cleaning solvent and the fabric articles, facilitating the separation and hence removal of additional quantities of the cleaning solvent from the fabric articles.
