摘要： A mass flow meter probe having an upstream tube and a downstream tube that extends into a main gas flow conduit is disclosed. The sensor for the mass flow measurement is located in the bore of a housing connecting the tubes and by incorporating the sensor into a valve that can block flow between the tubes, the mass flow meter can be calibrated in the field. The probe can be used as differential pressure device for flow measurments, when the valve is closed. A means for cleaning pressure ports is also disclosed.

摘要： A control system is provided for providing a constant flow of air through a chamber, such as a fume hood, by measuring the pressure of the air outside of the hood and comparing it with the pressure of the air within the hood and adjusting the flow of air to achieve a constant pressure difference. The system is particularly applicable to fume hoods which have a sash which can be opened or closed or left in intermediate position; the present system will provide a constant air flow through the hood regardless of the sash position.

摘要： New hexa-coordinate iron (II) complexes comprising compounds of formula (I) are described. These compounds comprise a tetradentate ligand with donor atoms comprising nitrogen and phosphorus. These complexes are shown for the first time to be useful catalysts for the hydrogenation of ketones, aldehydes, or imines to produce alcohols or amines, and the asymmetric hydrogenation of prochiral ketones or imines to produce non-racemic alcohols or amines. The source of the hydrogen can be hydrogen gas or a hydrogen-donating molecule such as isopropanol or hydrogen-donating mixture such as formic acid and an amine depending on the structure of the catalyst. In certain embodiments, the axial ligands on the catalyst comprise organonitrile ligands, carbonyl ligands, isonitrile ligands, or combinations thereof. The catalysts and the preparation thereof are disclosed. A reaction using phosphine and diamine precursors that is templated by the iron ion is the preferred route to the catalysts.

摘要： A system for optimizing the flow of air through a fume hood by dynamically controlling the air flow to provide a stable vortex in the vortex chamber of the hood, the optimum condition for minimizing backflow of fume-laden air through the hood doorway. A highly-sensitive pressure sensor disposed at a critical location in the vortex chamber sidewall senses minute variations in vortex pressure indicative of turbulence and sends signals via a transducer to an analog controller which uses proportional integral and adaptive gain algorithms to formulate output signals to an actuator which adjusts dampers in the hood to change the airflow into the vortex. The system operates in feedback mode and seeks a minimum in the amplitude of the sidewall pressure variations, indicating that turbulence has been eliminated and that a stable vortex exists. The pressure sensor signals can also be directed to an alarm to signal an off-standard and potentially dangerous condition.

摘要： A rotary actuator for converting reciprocating motion to rotary motion including a housing having spaced-apart end plates connected by guide rods. A bellows is provided having opposite sides one of which is connected to one of the end plates, the bellows being adapted to be connected to a source of fluid under pressure so that the bellows expands from a collapsed to an expanded position. A guide plate is provided movably mounted on the guide rods with the other bellows side being connected thereto. A rack and pinion assembly is provided mounted on the other end plate, the rack being connected to the guide plate so that expansion and contraction of the bellows causes linear movement of the rack thereby imparting rotary movement to the pinion. A spring acts between the guide plate and the other end plate thus resisting expansion of the bellows and returning it to the collapsed position upon the release of fluid pressure. Adjustable stops are provided for limiting rotational movement of the pinion between predetermined first and second angularly spaced positions.

摘要： The flow of air through a fume hood is optimized by producing a bi-stable vortex within the vortex chamber of the fume hood regardless of sash movement. A bi-stable fume hood optimizes capture face velocity to minimize backflow of fume laden air through the hood sash opening. This bi-stable vortex fume hood reduces the energy consumption up to sixty percent versus the present day mono-stable vortex fume hoods. The bi-stable vortex fume hood utilizes a vortex pressure control system to reposition top, center, and bottom slot openings of a baffle in the hood. This baffle moves the bi-stable vortex away from the fact when the sash is fully opened and creates a clearing action near the work surface as the sash is closed. The fume hood's airfoil is placed inside the fume hood chamber and the airfoil has multiple entry pattern, one of which turns the vortex up and away from the open sash window. The other creates flow which washes the work surface of the hood. The interior portion of the vortex chamber utilizes a turning vane in order to decrease dynamic losses and increase bi-stable vortex stability.

摘要翻译： 通过通风柜的空气流动通过在通风橱的涡流室内产生双稳态涡流而优化，而不管窗扇运动如何。 双稳态通风橱优化捕获面速度，以最大限度地减少吸烟烟气回流通过罩带窗口。 这种双稳态涡流通风机与目前的单稳态涡街通风机相比，能耗降低了百分之六十。 双稳态涡流罩采用涡流压力控制系统来重新定位罩中挡板的顶部，中心和底部槽口。 当挡板完全打开时，这个挡板将双稳态涡流移动离开事实，当窗扇关闭时，会在工作表面附近产生清除动作。 通风柜的翼型放置在通风橱室内，翼型具有多个入口模式，其中一个将涡流向上旋转并远离开放的窗框。 另一个产生洗涤罩的工作表面的流动。 涡流室的内部使用转动叶片，以减少动态损耗并增加双稳态涡流稳定性。
