摘要： A method and apparatus for sensing different levels of liquids in their respective containers in a liquid-consuming and/or producing instrument system. According to a preferred embodiment, an elongated liquid-sensing probe having axially spaced electrodes adapted to sense liquid at multiple levels is arranged in each container of liquid. A controller, e.g. a suitably programmed microprocessor, operates to selectively poll different pairs of electrodes carried by the probe to determine whether or not the polled electrode pairs are immersed in the contained liquid. Preferably, the polling circuit comprises an electronically-controlled resistor that serves to normalize the level-sensing output signal for liquids of different bulk resistivity.

摘要： A liquid aspiration device comprises an aspiration tube that slideably engages an opening in a cap such that a head on the end of the aspiration tube is moveable with respect to the opening in the cap. A tube cover is positioned between the opening in the cap and the head of the tube. The tube cover is operable to collapse into the cap when the head is moved into the cap. When the head and the tube cover are moved into the cap they are shielded from potential contamination that may occur when the aspiration device is moved from one container to the next. A lock is positioned in the cap. The lock is operable to move between an engaged position where the head may be retained within the cap and a disengaged position where the head is free to pass into or out of the cap.

摘要： A pressure equalization method and system is provided for starting a compressor while maintaining the condenser at a high pressure and includes a valve and a bleed port. The compressor has a compressor inlet for receiving a fluid at a first pressure and a compressor outlet for discharging the fluid at a second pressure, and is operable to compress the fluid from the first pressure to the second pressure. The valve is proximate to and in fluid communication with the compressor outlet and is movable to an open position when the compressor is operating to permit the fluid at the second pressure to flow through the valve and is movable to a closed position when the compressor stops operating to prevent backflow of the fluid at the second pressure through the valve toward the compressor inlet. The bleed port is upstream of the valve and in fluid communication with the compressor inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.
摘要翻译：提供了一种压力平衡方法和系统，用于启动压缩机，同时保持冷凝器处于高压，并包括阀和排气口。压缩机具有用于接收处于第一压力的流体的压缩机入口和用于在第二压力下排出流体的压缩机出口，并且可操作以将流体从第一压力压缩至第二压力。阀门与压缩机出口接近并且与压缩机出口流体连通，并且当压缩机运行时可移动到打开位置，以允许处于第二压力的流体流过阀门，并且当压缩机停止运行时可移动到关闭位置以防止在第二压力下的流体通过阀朝向压缩机入口的回流。泄放口位于阀的上游并与压缩机入口流体连通，以在压缩机停止运行时使包含在压缩机中的流体的压力相等。

摘要： Method and apparatus for controlling the temperature of one or more reaction vessels in a bio-chemical analyzer comprises a heat-exchange block, preferably made of cast aluminum or the like, and a thermoelectric device for heating or cooling the block to within a desired temperature range. The heat-transfer block cradles one or more reaction vessels in a thermal energy-transferring relationship, and further supports, in a thermal energy-transferring relationship, one or more fluid conduits serving to transmit a liquid or gas to the interior of the reaction vessels. Preferably, the heat-transfer block is cast from aluminum, and the fluid conduits are disposed inside the casting. By supporting the reaction vessel(s) and fluid conduit(s) in a common block, a single thermoelectric device and controller can be used to simultaneously control the respective temperatures of multiple fluid reagents and/or gases, as well as one or more reaction vessels, thereby reducing the power requirements of the thermal control system.

摘要： A compressor for providing automatic capacity modulation is disclosed. The compressor comprises a compression chamber, a compressing member, a reexpansion area, a flow passage, a valve member, and a biasing member. The flow passage is in fluid communication with the compression chamber and the reexpansion area. In one position, the valve member permits flow through the flow passage and in a second position it prevents flow. The valve member is subjected to a first operating condition of fluid on one side and a second operating condition of the fluid on the other side. The biasing member exerts a biasing force on the valve member. When the first operating condition reaches a predetermined point relative to the second operating condition, the valve member moves and effects a change in the capacity of the compressor.
