Abstract: A spaceship is provided with a freely spinning propeller mounted on the front end. The propeller significantly reduces resistance to flight and also deflects space particles which might otherwise slow the craft. The sides of the spacecraft have ridges which are coated on the front side with radiation reflecting material and on the back side with radiation absorbing material. The resultant force of radiations being absorbed from the rear and reflected from the front propels the spacecraft forward.

Abstract: A pair of protruding forms, shapes or objects serving as steering aids or safety devices affixed asymmetrically to the left side of the hood or radiator of a car, as viewed from the driver's seat, methodically situated in such a position as to correlate each of the two forms, designated as road delineators, to its adjacent boundary line of the traffic lane in order that the driver can determine conveniently, correctly and continuously the exact distance of the car from either boundary of the roadway, enabling motorists, as they maintain their normal driving posture, to avoid accidents.
