    摘要: A thermal transient anemometer provides mass flow rate or volume flow rate over smaller discrete regions of a larger flow field, i.e., the distribution of such rates over a predefined, larger area. The thermal transient anemometer comprises two components: a frame with a plurality of sensing cells each having a resistance wire grid and a control unit which includes an energy source which heats the resistance wire grid of each cell, measurement circuitry for determining the decay of resistance of the grid wires as they cool and computational circuitry which determines the mass or volume flow rate through each cell based upon such decay function.

    摘要: The present invention relates to cryogenic processes and systems for making and using high-pressure gas to quench or rapidly cool metals or other heated materials. The gas is preferably produced without pumps, compressors, and large high-pressure bulk storage tanks. The apparatus producing such gas comprises a cryogenic bulk storage tank, a pressure building apparatus, and a high-pressure vaporizer. A dew point monitor can be used to check gas purity to ensure uniform quenching and to prevent damage to the treated parts by, for example, water vapor. The method and system also may include a system that monitors the temperature, pressure, and level of liquid cryogen in the bulk storage tank and automatically calls in a refill for the storage tank.

    摘要: A retrofit technology for air-fuel fired, vertical glass furnace for oxygen firing or boosting to provide additional heat to the process to increase furnace production capacity. The additional firing using oxygen is strategically controlled to enable enhanced radiation from oxygen flame for the spheroidizing process without negative effects on the overall process. With proper implementation, an increased production from 50% to 200%, depending on the size of the spheres, can be achieved while maintaining acceptable product quality. Processes in accordance with the present invention can be performed using one of a number of methods of oxygen boosting.

    摘要: A cryogenic freezing method uses a mixture of liquid nitrogen and liquid oxygen in amounts approximating the composition of atmospheric air to freeze food products. The mixture preferably includes 18% to 25% oxygen and the balance nitrogen, with small amounts of residuals which are commonly found in air. The present invention involves replacing a liquid carbon dioxide or liquid nitrogen cooling medium which is used in known cryogenic freezers with a liquid nitrogen and liquid oxygen mixture. The liquid nitrogen and oxygen mixture can be used according the present invention in many of the known freezers using liquid carbon dioxide or liquid nitrogen as a cooling medium, including tunnel freezers, spiral freezers, and immersion freezers. The use of a liquid nitrogen and liquid oxygen mixture improves the efficiency of a freezer because the cold vapors are not exhausted from the freezer. In addition, the leakage of vapors from the freezer into the room air will not create unsafe conditions for workers.
