摘要： The force limited valve actuator operates on light-duty valves. The actuator includes signal controlled motor which drives a two piece threaded screw-nut drive. The nut connected to the motor and the screw connected to the valve stem. The nut has a spring loaded actuation surface/plate. The nut body has a positional indicator stem used as a valve-motor control. Operationally, the screw-nut-set moves between first, second and third positions. First: actuation plate at neutral and valve-stem at valve OPEN stop (example). Second: screw protrudes outboard of nut and valve-stem at CLOSE stop and actuation plate at neutral. Third: plate moves away from valve-stem (beyond neutral) while stem at CLOSE which third movement is a force sensor. First, second and third positions are all one way screw rotation. Force limited on stem by damper-shock absorber action. The positional indicator effects ON-OFF valve control.

摘要： A modular enclosure for housing various computing devices is provided. The modular enclosure includes a platform and a housing module mounted on the base module. The housing module has lateral sides, a front side, a rear side and a roof defining an interior volume for receiving the various computing devices and fan cassettes. Each fan cassette is provided with its own controller which is configured to adjust the rotational speed of the fan based on the power consumption of the one or more computing devices. When connected in a cluster, the fan cassettes provide a N+1 redundancy, wherein each cassette as an adjacent fan cassette configured as an active backup. The fan cassettes of a cluster communicate via a communication bus. The fan cassettes may include dampers to redirect air drawn from the computing devices back toward them in cold whether conditions, or toward the outdoors, in hot weather conditions.

摘要： The steam eyelet(s), mounted on steam dispersion tube(s), part of a steam dispersion system, has an interior cavity fed with steam, a through passage, a steam entry port and a steam exit port. The exit port is partly closed by a sloped throat which captures steam condensate and the steam entry port has a drain slot which drains condensate into the dispersion tube cavity. The eyelet's through passage progressively narrows at the exit with a shallow and then steep slope. A protruding lip reduces facial formation of condensate. A method reduces condensate spitting by accumulating condensate in the interior of the eyelet which, when it reaches a certain volume, drains the condensate bubble-droplet with an inboard interior eyelet surface disruption near the steam entry. Surface tension of the condensate bubble-droplet is used to drain the bubble-droplet at the disruption, causing an out-flow of the bubble-droplet in a direction contrary to steam flow.
摘要翻译： 安装在蒸汽分散管（蒸汽分散系统）的一部分上的蒸汽孔眼具有供给蒸汽，通道，蒸汽入口和蒸汽出口的内部空腔。 出口通过倾斜的喉部部分地闭合，其捕获蒸汽冷凝物，并且蒸汽进入端口具有将冷凝物排入分散管腔的排水槽。 孔眼的通道在出口处逐渐变窄，斜坡较陡峭。 突出的唇缘减少冷凝物的面部形成。 一种方法通过在孔眼的内部积聚冷凝物来减少冷凝物的吐出，当其达到一定的体积时，在蒸汽进入附近内部具有内侧内孔眼表面破裂的情况下排出冷凝物气泡。 使用冷凝物气泡液滴的表面张力在破裂时排出气泡液滴，导致气泡液滴在与蒸汽流相反的方向上流出。

摘要： Supplied humidification steam is dispersed through tubes and a header. Condensate is collected from the header into a tank. A controlled steam supply valve pumps condensate from the tank to a return line by application of sourced steam. A non-mechanical electronic level sensor (ELS, sensing temperature, resistance, capacitance, inductance, luminance or sonic condition of condensate) signals a controller using the ELS and/or a timed pumping/evacuation cycle to push condensate from the tank to the return. The method removes condensate by isolating the collection tank from the tubes and header and pumps condensate from the tank based upon a sensed conditions.
