Abstract: A bistable double-acting valve includes a valve body having two opposed compression surfaces and an elongated spring element located between the two compression surfaces and having a first end pivotally secured to the valve port and its other end secured to an actuating lever. The length of the spring is such that a smooth curve is formed between its two ends in each of the two bistable positions, and in each bistable position the spring clamps a section of tubing against a corresponding compression surface to block fluid flow through that tubing.

Abstract translation: 双稳态双作用阀包括具有两个相对的压缩表面的阀体和位于两个压缩表面之间的细长弹簧元件，并且具有枢转地固定到阀口的第一端，并且其另一端固定在致动杠杆上。 弹簧的长度使得在其两个双稳态位置中的每一个中在其两端之间形成平滑的曲线，并且在每个双稳态位置中，弹簧将一段管道抵靠相应的压缩表面夹紧以阻止通过该管道的流体流动。

Abstract: Fluid analysis apparatus includes a sample chamber that has a constituent sensor in it and an inlet conduit connected to the sample chamber. A heater assembly surrounds the inlet conduit. The heater assembly includes a preheater stage, a final heater stage, and a heat supply stage disposed between the preheater and final stages. Tempering fluid is flowed sequentially through the preheater stage, the heat supply stage and final stage and around the sample chamber for maintaining the sample chamber and the constituent sensor at a stable temperature and heating the sample to that same temperature as it flows through the inlet conduit.

Abstract: A fluid sample analysis instrument includes two sample chambers with an electrode assembly associated with each sample chamber. The instrument includes a common pump system for applying reduced pressure to the sample chambers to produce flow of fluid into and out of the sample chambers and a common circulator system for circulating fluid past the electrode assemblies and sample chambers to maintain the sample chambers and electrode assemblies at a pre-established temperature.
