Abstract: Wear on the dressing tool is derived from an amount of movement that a grinding wheel is advanced until issuance of a signal from a sizing device for correcting data on the radius of the grinding wheel. The data on the radius of the grinding wheel is thus indicative of an actual radius of the grinding wheel regardless of a variation in the grinding wheel radius due to the wear of a dressing tool. Accordingly, the grinding surface of the grinding wheel can be exactly positioned at a grinding start position after the grinding wheel has been returned to its original position upon power supply failure, emergency machine shutdown or the like, so that any unwanted interference between the grinding wheel and a workpiece can be avoided.

Abstract: An engine having a working chamber and a combustion chamber and a method for operating it are disclosed. The amount and compression ratio of air entering the combustion chamber are controlled by valves at the working chamber. The maximum possible amount of air is inducted into the working chamber, and then air is discharged until an amount necessary for the existing load on the engine remains.

A proportional amount of fuel is supplied, and the resulting combustion gas is then transferred to do work in the working chamber. The amount of combustion gas transferred is sufficient to maintain a substantially constant pressure in the combustion chamber.

Abstract: Positive displacement isothermal gas cycle machinery is designed with explicit control of the heat flow between the gas, the walls of the chamber and a thermal reservoir externally of the chamber. The control is achieved by providing a large chamber wall area to chamber volume ratio through the use of bellows-like walls having a configuration that ensures during each stroke numerous heat exchanges between the working gas and the bellows-like walls. The machinery includes Stirling cycle heat pumps and motors and isothermal compressors. Significant gains in thermal efficiency, up to a factor of 2, are attainable because the largest inefficiency in all isothermal machinery is imperfect control of heat flow. A regenerator for the isothermal machinery minimizes cycle losses due to gas transfer friction, gas thermal conduction, dead volume, regenerator heat mass, regenerator heat mass thermal skin depth, and regenerator mass thermal conductivity in the gas flow direction.
