    • Disclosed embodiments address contaminant management challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, and further address the more serious challenges that arise under intermittent operation of PSA equipment. One disclosed embodiment of a PSA apparatus, intended primarily for normal operating cycle speeds of at least 3 cycles per minute, includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end through a shutoff valve closed during production and open during shutdown. Other disclosed embodiments of the PSA apparatus used particular sealing strategies for additional sealing of the apparatus, or at least components thereof, from contaminant ingress. For example, one embodiment comprises a buffer seal for receiving a buffer gas having a contaminant vapor content substantially the same as or less than a product gas produced by a pressure swing adsorption process over the adsorbers. The buffer chamber may have flushing circulation provided by delivered product flow. As a second example of sealing strategy, a parking seal can be used that typically is engaged when the apparatus is parked. The parking seal can be used alone, or in combination with other contaminant management features. Embodiments of a method for reducing adsorbent degradation by contaminant adsorption while producing a product gas also are described comprising providing described embodiments of the PSA apparatus or system, and operating such PSA apparatus or system to produce a product gas. Various embodiments for operating a PSA apparatus and system during normal product delivery, shutdown, park and start up modes also are described.
    • 公开的实施例解决了在PSA设备的操作中生产期望的无污染物质流体期间产生的污染物管理挑战,并且进一步解决了在PSA设备的间歇操作下出现的更严重的挑战。 主要用于每分钟至少3个循环的正常操作循环速度的PSA装置的一个公开实施例包括与吸附器的进料端流体耦合的通气器,其具有污染物敏感性吸附剂。 呼吸器可以通过在生产期间关闭的截止阀与关闭时关闭时打开相连接。 PSA设备的其它公开的实施例使用特定的密封策略来附加地密封设备,或至少其组件,以免污染物进入。 例如,一个实施例包括用于接收缓冲气体的缓冲密封件,该缓冲气体的污染物蒸汽含量基本上等于或小于通过吸附器上的变压吸附过程产生的产物气体。 缓冲室可以具有由输送的产品流提供的冲洗循环。 作为密封策略的第二示例,可以使用通常在设备停放时接合的停车密封件。 停车密封件可以单独使用,也可以与其他污染物管理功能结合使用。 还描述了在制造产品气体的同时通过污染物吸附降低吸附剂降解的方法的实施方案,其包括提供PSA装置或系统的所述实施方案,以及操作这种PSA装置或系统以产生产物气体。 还描述了在正常产品递送,关闭,停放和启动模式期间操作PSA装置和系统的各种实施例。

    • An improvement in a magnetic resonance method for determining at least one property of multiple samples, including introducing multiple samples into the interrogation zone simultaneously; applying a gradient magnetic field to the interrogation zone wherein different positions within the interrogation zone are sensitive to different specific frequencies; monitoring energy emitted by the samples in the different positions and generating an output signal having a characteristic which is proportional to the energy emitted corresponding thereto in different frequency bands; and, attributing the signals to specific positions and samples, and comparing the output signal characteristics of the specific positions and samples with like data obtained from at least one similar sample to provide an indication of the corresponding property of the samples.
    • 用于确定多个样品的至少一个性质的磁共振方法的改进,包括同时将多个样品引入询问区; 向询问区施加梯度磁场,其中询问区内的不同位置对不同的特定频率敏感; 监测由不同位置的样本发射的能量,并产生具有与在不同频段对应的能量成比例的特性的输出信号; 以及将信号归因于特定位置和样本,并且将特定位置和样本的输出信号特征与从至少一个类似样本获得的相似数据进行比较,以提供样本的相应属性的指示。

    • A method for melting glass forming batch material includes charging the glass forming batch material to a glass melting apparatus; impinging a flame proximate to the surface of the batch materials to form a glass melt from the batch material; and bubbling the glass melt in proximity to the impinging flame with a fluid, advantageously producing a shearing action sufficient to enhance the solution rate of the glass forming batch material relative to the same system without bubbling, but without splashing glass and without significant production of seeds or blisters in the glass melt. Melting of the glass forming batch material with bubbling proceeds more quickly, and/or at lower temperatures than occurs in a comparable conventional glass melting furnace.
    • 用于熔化成型玻璃的批料的方法包括将玻璃形成批料材料装入玻璃熔化装置; 撞击靠近批料的表面的火焰,以从批料中形成玻璃熔体; 并用流体鼓泡玻璃熔体靠近撞击火焰,有利地产生剪切作用,足以增加相对于相同体系的玻璃形成批料的溶液速率而不起泡,但不溅飞玻璃并且没有显着生产种子 或玻璃熔体中的水泡。 用比较常规的玻璃熔化炉中熔化的玻璃形成批料材料进行更快速和/或更低的温度。
