Anti-surge speed control for two or more compressors
The present invention relates to a method and control system to control the speed of centrifugal compressors operating within a vacuum pressure swing adsorption process to avoid an operation at which surge can occur and directly driven by an electric motor that is in turn controlled by a variable frequency drive, while subsequently operating the vacuum pressure swing process between set limits of highest adsorption and lowest desorption pressure. In accordance with present invention an optimal speed for operation of the compressor is determined at which the compressor will operate along a peak efficiency operating line of a compressor map thereof. This speed is adjusted by a feed back speed multiplier when the flow or other parameter referable to flow through the compressor is below a minimum and a feed forward multiplier during evacuation and evacuation with purge steps that multiplies the feed back multiplier to increase speed of the compressor and thereby avoid surge. The speed is then adjusted by a global speed factor which serves to adjust the average speed of the motors over all steps of the repeating cycle such that the process operates within high and low pressure limits. |

Resonant unidirectional wave energy converter
A wave energy conversion device whereby its structural design and positioning converts oscillating wave energy into unidirectional wave induced water flow. A judiciously placed upper closed perimeter boundary positioned on a submerged horizontally oriented surface pierced with an opening, focuses incident waves inward creating a resonant wave condition where the superposition of waves induces a predominantly downward unidirectional flow through the opening. A segmented sealed upper boundary results in the additional storage of water head due to the overtopping of waves, thus further smoothening and increasing the magnitude of the unidirectional flow. This wave energy converter can be utilized with unidirectional hydro turbines for electrical power generation. |

Decompression kneader
Provided is a decompression kneader capable of stabilizing a moisture content of resultant kneaded sand. The decompression kneader includes a kneader main body configured to knead casting sand and water, a decompression pump configured to reduce a pressure inside the kneader main body, a condenser configured to condense water vapor sucked by the decompression pump, a tank configured to store water condensed by the condenser, and a supply amount calculation apparatus configured to calculate an amount of water supplied from the tank to the kneader main body. The tank comprises a water gauge and a weighing scale, and the supply amount calculation apparatus estimates an amount of the casting sand contained in the tank based on measured values of the water gauge and the weighing scale and corrects the amount of the water supplied from the tank with reference to the amount of the casting sand. |

Sand mold shaping material, and method for shaping sand mold using same
A sand mold shaping material contains an aggregate comprising inorganic particles, and microcapsules enclosing a binder which causes the aggregate to bind. The binder is a liquid binder that is in a liquid phase at room temperature, and is enclosed in an outer shell comprising a resin that forms the microcapsule. The sand mold shaping material is in a dry state when used to fill a molding die for shaping. |
