  • Patent number: 8540013
    Abstract: A heat exchanger with a plurality of heat transfer plates between a frame and a movable plate employs hydraulic rams connected above and below the heat transfer plates to move the movable plate toward or away from the frame in a releasable clamping action against the heat transfer plates. A positive lock maintains the movable plate in its operational position. Supports above and below the heat transfer plates support and guide the movable plate and heat transfer plates. Thus, the heat transfer plates are removable from between the stationary and follower plates for replacement and maintenance when the movable plate is moved away from the frame without further reconfiguration or dismantling of the plate heat exchanger.

  • Patent number: 7398841
    Abstract: An energy conversion apparatus and method using recovered energy sources including motor vehicle kinetic energy (deceleration and shock) and wind resistance, supplemented by liquefied air transferred to the vehicle and by solar radiation thereto. The energy sources are combined, as available, to drive a compressor for supplying intake working fluid of a motor vehicle prime mover, wherein liquefied air provides pre-compression cooling of an atmospheric air portion of the working fluid. The liquefied air is made by recovered energy, stored and transferred between vehicles and between vehicles and stationary sites. In a hybrid version of the vehicle, exhaust heat from a combustion engine part of the prime mover increases working fluid temperature in a gas expander part, thereof; the engine and expander operating independently or together for improved vehicle propulsion efficiency.

  • Patent number: 7302807
    Abstract: In a refrigerating cycle device using carbon dioxide as a refrigerant, there exists a problem that the provision of a receiver at a low-pressure side increases cost and volume due to a pressure resistance design necessary for ensuring safety. By adjusting a refrigerant holding quantity of a first heat exchanger in such a manner that a refrigerant pressure of the first heat exchanger 13 is changed by operating a first decompressor 12 and a second decompressor 15, an imbalance of a refrigerant quantity between time for space cooling and time for heating or dehumidifying can be alleviated and hence, it is possible to perform an operation of the refrigerating cycle device with high efficiency with a miniaturized receiver or without providing the receiver.

  • Patent number: 7297055
    Abstract: A method of generating a high-level vacuum comprises evacuating a chamber having a substantially-pure gas therein to a medium-level vacuum, and freezing the residual gas to generate the high-level vacuum within the chamber. Impurities, such as atmospheric air, may be purged from the chamber by evacuating the chamber to a medium level vacuum (e.g., around 10?2 Torr) and subsequently filling the chamber with the gas. This purging process may be repeated multiple times to decrease the level of impurities in the gas filling the chamber. The substantially-pure gas may have an impurity-level of less than approximately 100 PPM and may comprise carbon-dioxide, although the scope of the invention is not limited in this respect. The medium level vacuum may range between approximately 1×10?2 Torr and 5×10?2 Torr allowing the use of a roughing pump, and the high-level vacuum may range between approximately 1×10?5 and 1×10?8 Torr.

  • Patent number: RE40124
    Abstract: A process for the high-yield recovery of ethylene and heavier hydrocarbons from the gas produced by pyrolysis of hydrocarbons in which the liquid products resulting from the fractionated condensation of a cracking gas for the recovery of almost all the ethylene, are supplied to a distillation column, called a de-ethanizer, at different intermediate levels. At the top of the de-ethanizer the vapor of the column distillate is treated directly in an acetylene hydrogenation reactor, the effluent containing virtually no acetylene being separated by a distillation column called a de-methanizer, into an ethylene- and ethane-enriched tail product, while the head product is recycled by compression or treated for subsequent recovery of ethylene.
