    摘要： The invention includes a system for monitoring the performance of an automatic dosing siphon utilized in reservoir which is a part of a wastewater treatment system. The siphon includes a bell type cover, a fluid trap having one leg extending upward into the bell, and an outlet discharge pipe connected to said trap. A flow detect switch is located in the discharge pipe. Upon siphon activation the switch is opened and a countdown timer is reset. After draining the reservoir, the switch closes and the timer starts counting down a predetermined time period. If the siphon doesn't activate, time expires and an alarm is triggered. A second system utilizes a solenoid drain valve located above the outlet portion of the siphon trap such that upon time expiring the valve opens, the tank drains, and the timer resets. The valve automatically reprimes the siphon. The system continues to monitor the siphon and initiates an alarm upon subsequent siphon failures. Another system for restarting the siphon replaces the solenoid valve with an air pump whose air hose is situated under the siphon bell. Upon time expiring, the air pump activates and pumps air under the siphon bell thereby activating the siphon. The tank drains, the switch closes, and the siphon is reprimed for normal operations. A second timer counts down after the activation of the air pump or solenoid valve. If the switch is not opened within the second predetermined time period, an alarm is triggered.

    摘要翻译： 本发明包括用于监测在作为废水处理系统的一部分的储存器中使用的自动计量虹吸管的性能的系统。 虹吸管包括钟形盖，具有向上延伸到钟形中的一条腿的流体阱，以及连接到所述陷阱的出口排放管。 流量检测开关位于排放管中。 虹吸激活后，开关打开，倒计时器复位。 在储存器排水后，开关关闭，定时器在预定时间段内开始倒计时。 如果虹吸管未激活，则时间到期并触发报警。 第二个系统利用位于虹吸收集器的出口部分上方的电磁排放阀，使得当阀门打开时，罐排出并定时器复位。 阀门自动重新排列虹吸管。 系统继续监视虹吸管，并在后续虹吸管故障时启动报警。 用于重新启动虹吸的另一个系统用空气软管位于虹吸钟下方的气泵代替电磁阀。 时间到期后，空气泵启动并抽吸虹吸钟下方的空气，从而启动虹吸管。 水箱排水，开关关闭，虹吸管进行正常操作。 启动气泵或电磁阀后，第二个定时器倒计时。 如果在第二预定时间段内没有打开开关，则触发报警。

    摘要： A generally L-shaped bicycle rack includes upper and lower intersecting leg portions, each including side walls having outwardly extending peripheral flanges which may optionally engage nails or screws for the purpose of securing the rack in a selected location. An arcuate well disposed centrally in the rack receives an outer circumferential portion of a bicycle wheel to support a bicycle for storage purposes. Aligned pairs of notches in the peripheral flanges of the upper and lower legs allows one or more of the racks to be secured in a variety of different mounting configurations. In a first alternative, the rack may be secured to a vertical wall to store a bicycle in a vertical orientation. In a second alternative, a plurality of racks may be secured in sequential adjacent relation to form a rack for storing multiple bicycles. A tubular member extending transversely through the upper leg of the rack may receive cables or chains for locking a bicycle to the rack. Alternatively, one or more of the racks may be mounted in a selected location by passing a chain, cable, or pipe through the tubular member. The rack has a lightweight open hollow construction which allows storage and shipping of a plurality of racks in nested stacked relation to minimize shipping and storage costs.

    摘要翻译： 大致L形的自行车架包括上部和下部相交的脚部分，每个腿部部分包括具有向外延伸的周向凸缘的侧壁，该周边凸缘可以可选地接合钉子或螺钉，以将机架固定在选定位置。 在机架中央布置的弧形部件容纳自行车车轮的外圆周部分，以支撑用于存储目的的自行车。 在上腿和下腿的周边法兰中对准的成对的切口允许一个或多个齿条以各种不同的安装构造被固定。 在第一替代方案中，机架可以固定到垂直壁以将自行车存放在垂直方向上。 在第二替代方案中，可以以顺序的相邻关系固定多个机架，以形成用于存储多个自行车的机架。 横向延伸穿过机架的上腿的管状构件可以接收用于将自行车锁定到机架的电缆或链条。 或者，可以通过使链条，电缆或管道穿过管状构件来将一个或多个机架安装在选定位置。 机架具有轻质的开放中空结构，其允许以嵌套的堆叠关系存储和运输多个机架，以最小化运输和存储成本。
