  • Patent number: 8205593
    Abstract: Method and apparatus to improve the efficiency of internal combustion engines in which compression and combustion of an Air/Fuel mixture is carried out without a compression stroke as used in conventional internal combustion engines and expansion of the combusted mixture is performed to increase the expansion ratio resulting in an increase in the amount of work extracted. An externally compressed Air/Fuel Mixture is combusted in a variable volume combustion chamber and expanded into a conventional cylinder displacing a power piston to produce rotation of a crankshaft to drive a vehicle or other device. Separation of the variable volume combustion chamber from the conventional cylinder eliminates the conventional Otto Cycle compression stroke and provides a substantially larger expansion ratio than the compression ratio in a conventional engine.

  • Publication number: 20110036324
    Abstract: An improved method and apparatus for increasing the efficiency of internal combustion engines in which compression and combustion of an Air/Fuel mixture is carried out without a compression stroke as used in conventional internal combustion engines and expansion of the combusted mixture is performed to significantly increase the expansion ratio resulting in a significant increase in the amount of work extracted from the expansion of combusted mixture. Several embodiments are described. In the preferred embodiment externally compressed Air/Fuel Mixture is combusted in a variable volume combustion chamber and then expanded into a conventional cylinder displacing a power piston to produce rotation of a conventional crankshaft to drive a vehicle or other device.

  • Patent number: 4399836
    Abstract: The invention contemplates an electrically operated valve construction for control of fluid flow wherein an actuator module is adapted for detachable connection to a valve-body module which contains the valve member to be automatically positioned by a driver element of the actuator module. All electronic components for moving the driver element are self-contained in the actuator module, and these elements include a fluid-sensing transducer producing an electrical output, for closure of the control loop. The transducer has sealed exclusive exposure to fluid in the valve-body module via a special port within the confines of the interface between the modules, when the modules are assembled to each other; this port communicates directly with that part of the valve-body passage which is on the downstream side of the valve member.

  • Patent number: 4044580
    Abstract: Rolling mills, especially for sheet metal, and also paper, rubber and similar rolling mills, require accurate control of the gap between the rolls since this determines the uniformity of the gauge of the material rolled by the mill. This invention provides a rolling mill with sensors that cooperate with the circumferential surfaces of the rolls, or rigid parts thereof, to detect relative movement of the rolls in directions that affect the roll gap and the gauge of the material being rolled. Response of the sensors operates a transducer to affect automatic correction of changes in the spacing of the rolls from one another.
