摘要： A ballast for a gas discharge lamp includes a detection circuit which detects an operating state of the lamp in which the lamp current for the column discharge of one polarity is different from the lamp current for the column discharge of the other polarity by detecting the DC component of the voltage across the discharge lamp. The detection circuit includes (i) a device coupled such that a DC voltage is imposed there across when the lamp current is different for the column discharge according to one polarity verses the other polarity, and (ii) a sensing circuit for sensing the DC voltage across the device. The device may be a capacitive device, and in a particularly inexpensive implementation, is a DC blocking capacitor or a ballast capacitor. The sense circuit senses when the DC voltage across the device exceeds a threshold value, which may corresponds to fully-rectified state of the lamp or more favorably, to a lesser state of imbalance. In another embodiment, the variance in the DC voltage across the lamp is detected at the midpoint of a bridge inverter. A control circuit changes the output of the ballasting circuit when the DC voltage exceeds the threshold value to turn off the lamp or to recurrently cycle the lamp on and off to signal the user that the lamp needs to be changed.
摘要翻译：用于气体放电灯的镇流器包括检测电路，该检测电路通过检测DC分量来检测一极性的列排出的灯电流与用于另一极性的列放电的灯电流不同的灯的工作状态的放电灯两端的电压。检测电路包括（i）耦合的器件，使得当灯电流根据一种极性与另一极性相反的列电压不同时，直流电压被施加到该电极上，以及（ii）用于感测直流电压的感测电路跨设备。该装置可以是电容性装置，并且在特别廉价的实施方式中，是直流阻塞电容器或镇流电容器。感测电路感测器件上的直流电压何时超过阈值，其可以对应于灯的完全整流状态或更有利地达到较小的不平衡状态。在另一个实施例中，在桥式逆变器的中点处检测灯两端的直流电压的变化。当直流电压超过阈值时，控制电路改变镇流电路的输出，以关闭灯泡或打开或关闭灯泡，以便向用户发出指示灯需要改变的信号。

摘要： A multistage plunger lift system includes an upper production tubing segment positioned in a wellbore uphole of a lower production tubing segment, with the upper segment having a greater diameter than the lower segment. A lower travelling plunger and an upper traveling plunger are sized and configured to fit and travel within the lower segment and the upper segment, respectively. A plunger lift tool is positioned in the upper segment between the upper plunger and the lower plunger, and includes within its main body a fluid passageway with a one-way valve. A plunger receptacle sleeve at the bottom end of the lift tool receives the lower plunger and includes one or more vents configured to allow fluids to flow around the lower plunger when the lower plunger is received within the plunger receptacle sleeve.

摘要： A jet pump, a jet pump data tool system, and method of use thereof. The jet pump includes a body having an intake, a first aperture, and a second aperture between the first aperture and the intake. A carrier is seated in the body and receivable in the first aperture. The carrier includes a venturi for drawing wellbore fluid from the intake into the venturi. A housing for a data tool extends from the carrier. The housing is in fluid communication with the intake for allowing wellbore fluid to be exposed to the data tool. The carrier is seatable in the body by flowing power fluid and the carrier into the first aperture. The carrier is retrievable from the body by flowing power fluid into the second aperture.
