The paper reviews some of the salient points arising in the design and development of the modern high-output air-cooled cylinder. It is based to a very large extent upon the work of Dr. A. H. Gibson ...

CURRENT interest in the removal of films of contaminants from water by rotating cylinders has prompted an investigation of the mechanism. Remarkable effects are observed when a small cylinder is ...

Piston engines are subject to cyclic vibrations due to the motion of the crank and pistons inside the engine. The vibrations are most obvious in single cylinder engines. As the number of cylinders is ...
