  • Patent number: 10469155
    Abstract: Various implementations disclosed herein enable transforming mutable wireless coverage areas using network coverage vehicles (NVCs) that are orchestrated by a network coverage controller. In various implementations, the method includes receiving coverage area performance characterization values from NCVs configured to provide a plurality of mutable wireless coverage areas. In various implementations, an arrangement of the mutable wireless coverage areas mutably defines the service area, which changes in accordance with changes to the arrangement of the mutable wireless coverage areas. In various implementations, the method also includes determining NCV operation adjustments for some of the NCVs based on the received coverage area performance characterization values in accordance with a service performance metric; and, altering an arrangement of one or more of the plurality of mutable wireless coverage areas within the service area by providing the NCV operation adjustments to some of the NCVs.

  • Patent number: 10260379
    Abstract: The present invention provides a method of operating an engine (14) having one or more cylinders (16) each having a piston (18) within the cylinder (16) and each piston (18) having an expansion stroke and a return stroke and a top dead center (TDC) position and a bottom dead center position (BDC) and said engine (14) employing a working fluid (WF) and a heat exchange fluid (HEF), comprising the steps of: introducing the HEF during the return stroke of the engine; introducing the working fluid (WF) during the expansion stroke of the engine; causing the exhaust valve to be opened at or near bottom dead center of the piston BDC; delivering the HEF to the cylinder (16) after the exhaust valve has been opened; and closing the exhaust valve before TDC, such as to allow the working fluid to be compressed by the piston within the cylinder. The invention also provides an engine (14) capable of being operated in accordance with the method.

  • Patent number: 9884546
    Abstract: A system (100) comprises a cryogenic engine (16) and a power generation apparatus, wherein the cryogenic engine and the power generation apparatus are coupled with each other to permit the cryogenic engine (16) and the power generation apparatus to work co-operatively with each other in a synergistic manner. The cryogenic engine (16) and the power generation apparatus are mechanically and optionally thermally coupled with each other so that the output means is shared between the cryogenic engine (16) and the power generation apparatus and that the two systems can be operated in the most power efficient manner and may also thermally interact to the potential advantage of both performance and economy.

  • Patent number: 9388711
    Abstract: A cryogenic engine system and method for delivering cryogen to a cryogenic engine are provided. The cryogenic engine system comprises a tank for storing liquid cryogen, a cryogenic engine, a pump configured to pressurize cryogen from the tank, a first conduit for transporting cryogen between the pump and the cryogenic engine, a second conduit for transporting cryogen from the pump back to the tank, and a first valve disposed in the second conduit for controlling the flow of cryogen from the pump back to the tank. A pre-mixing system for a cryogenic engine and a method for mixing cryogen with a heat exchange fluid (HEF) are also provided.

  • Patent number: 5775129
    Abstract: A heat exchanger for use within a sump to condense an vapor and to vaporize the liquid. The heat exchanger includes a core having alternating passages to vaporize the liquid and to condense the vapor. Liquid is distributed into passages through a liquid distributor and the passages involved in vaporizing the liquid are provided with a down flow, stage and one or more thermosiphon stages situated below the down flow stage. In such manner, part of the liquid is vaporized within the down flow stage and the remainder is vaporized within the thermosiphon stage or stages.

  • Patent number: 5667643
    Abstract: A heat exchanger is provided which is suitable for use as a condenser/reboiler in a double distillation column. The heat exchanger has alternating first and second passages and a reservoir located above the first and second passages for receiving a first fluid and for containing a froth. A series of orifices can be provided by a distributor tray to provide flow communication between the reservoir and the first passages to allow at least a liquid phase of the froth to weep into the first passages and to be partly vaporized through indirect heat exchange with a second fluid flowing through the second passages. The partial vaporization produces a vapor phase of the froth which can at least in part escape from the orifices and interact with the first fluid to thereby form the froth. A remaining part of the liquid phase, not vaporized through the indirect heat exchange, is discharged from the bottom of the first passages into a sump.
