    • A system for separating particles entrained in a fluid includes a base with a first channel and a second channel. A precision gap connects the first channel and the second channel. The precision gap is of a size that allows small particles to pass from the first channel into the second channel and prevents large particles from the first channel into the second channel. A cover is positioned over the base unit, the first channel, the precision gap, and the second channel. An port directs the fluid containing the entrained particles into the first channel. An output port directs the large particles out of the first channel. A port connected to the second channel directs the small particles out of the second channel.
    • 用于分离夹带在流体中的颗粒的系统包括具有第一通道和第二通道的底座。 精密间隙连接第一通道和第二通道。 精密间隙具有允许小颗粒从第一通道进入第二通道并防止大颗粒从第一通道进入第二通道的尺寸。 盖子位于基座单元上,第一通道,精密间隙和第二通道上。 端口将含有夹带的颗粒的流体引导到第一通道中。 输出端口将大颗粒引导出第一个通道。 连接到第二通道的端口将小颗粒引导出第二通道。

    • A method of delivering messages between application programs is provided which ensures that no messages are lost and none are delivered more than once. The method uses asynchronous message queuing. One or more queue manager programs (100) is located at each computer of a network for controlling the transmission of messages to and from that computer. Messages to be transmitted to a different queue manager are put onto special transmission queues (120). Transmission to an adjacent queue manager comprises a sending process (130) on the local queue manager (100) getting messages from a transmission queue and sending them as a batch of messages within a syncpoint-manager-controlled unit of work. A receiving process (150) on the receiving queue manager receives the messages and puts them within a second syncpoint-manager-controlled unit of work to queues (180) that are under the control of the receiving queue manager. Commitment of the batch is coordinated by the sender transmitting a request for commitment and for confirmation of commitment with the last message of the batch, commit at the sender then being triggered by the confirmation that is sent by the receiver in response to the request. The invention avoids the additional message flow that is a feature of two-phase commit procedures, avoiding the need for resource managers to synchronise with each other. It further reduces the commit flows by permitting batching of a number of messages.
    • 提供了一种在应用程序之间传递消息的方法,其确保没有消息丢失,并且不再传送消息多于一次。 该方法使用异步消息队列。 一个或多个队列管理器程序(100)位于网络的每个计算机上,用于控制到该计算机的消息的传送。 要发送到不同队列管理器的消息被置于特殊传输队列(120)上。 向相邻队列管理器的传输包括本地队列管理器(100)上的发送进程(130),从发送队列获取消息,并将它们作为同步点 - 管理器控制的工作单元内的一批消息发送。 接收队列管理器上的接收过程(150)接收消息并将它们置于第二同步点 - 管理器控制的工作单元中,以处理在接收队列管理器的控制下的队列(180)。 批量的承诺由发送方发送承诺请求和用于确认批次的最后消息进行协调,在发送方提交,然后由接收方响应请求发送的确认触发。 发明避免了作为两阶段提交过程的特征的附加消息流,避免了资源管理器彼此同步的需要。 它进一步减少提交流量,允许批处理多个消息。
