摘要： A two part variable compression ratio (VCR) piston assembly having an outer member movable relative to an inner member to vary the compression ratio of an internal combustion engine and a hydraulic system utilizing oil from the lubrication system of the engine for automatically controlling the relative movement of the members to maintain a predetermined maximum combustion chamber pressure. A hydraulic circuit includes an upper and a lower chamber which expands and contracts conversely upon relative movement of the piston members and a system for supplying oil to the upper chamber and to the lower chamber via the upper chamber and for discharging the oil from the upper chamber in a manner which gradually changes the compression ratio of the piston until a predetermined maximum combustion chamber pressure has been achieved and which tends to maintain the maximum combustion chamber pressure after it has been achieved. The lower chamber is disposed adjacent the piston ring area and a sealing ring is utilized as a valve for regulating oil flow from the upper chamber to the lower chamber.

摘要： A hard, wear-resistant ceramic surface is applied to spinning rotor cups in an electrolytic bath on which is imposed a shaped-wave electric current. A special electrode has been designed to facilitate application of the coating to the unique shape of a spinning rotor cup under the shaped wave conditions.

摘要： Liquid transfer rolls such as printing rolls are made by imposing a hard ceramic coating on an incipient liquid transfer roll in an electrolytic bath subjected to a modified shaped wave alternating current, which causes dielectric breakdown and the formation of a hard ceramic coating on the roll. The roll is laser engraved to form liquid carrying reservoirs or cells on the surface of the roll, either before or after the ceramic coating is built on the roll.

The lower chamber is disposed adjacent the piston ring area of the piston assembly and the hydraulic system includes an uniquely formed pressure responsive relief valve to discharge oil from the upper chamber to the crankcase of the engine upon a predetermined pressure being produced in that chamber.
