Abstract: A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.

Abstract: Provided herein are passive microfluidic pumps. The pumps can comprise a fluid inlet, an absorbent region, a resistive region fluidly connecting the fluid inlet and the absorbent region, and an evaporation barrier enclosing the resistive region, the absorbent region, or a combination thereof. The resistive region can comprise a first porous medium, and a fluidly non-conducting boundary defining a path for fluid flow through the first porous medium from the fluid inlet to the absorbent region. The absorbent region can comprise a fluidly non-conducting boundary defining a volume of a second porous medium sized to absorb a predetermined volume of fluid imbibed from the resistive region. The resistive region and the absorbent region can be configured to establish a capillary-driven fluid front advancing from the fluid inlet through the resistive region to the absorbent region when the fluid inlet is contacted with fluid.

Abstract: Disclosed is a device for gas replacement capable of reducing the amount of replacement gas, improving a gas replacement rate, and reducing the amount of split liquid. In a replacement nozzle (11) which blows the replacement gas toward a container opening portion symmetrically about a center line in the container radial direction, the space between nozzle port outermost walls is divided with a plurality of wind direction adjustment plates (16a, 16b) to generate a plurality of blowout ports. The replacement gas flow blowing along the outermost walls of the nozzle opening are so blown inward as to form an angle of 100° to 130°. Moreover, the replacement gas is blown from the replacement nozzle to the range between the level lower than the end of the can opening by one third or more the height of the can neck portion and the level equal to or higher than the height of the can cover.

Abstract: Techniques are generally described that include electrokinetic pumping an emulsion comprising an ionic fluid and a nonpolar fluid to promote flow of the ionic fluid by electro-osmotic flow and drag the nonpolar fluid by viscous drag forces. In some examples, the electrokinetic pump may be utilized to deliver one or more reagents within a fluidic reactor system, such as a micro-scale reactor system. In some additional examples, a reagent may be dissolved in the nonpolar fluid of a first emulsion and pumped through the electrokinetic pump to a mixing channel to allow the reagent of the first emulsion to react with a reagent of second emulsion to form a reactive product.

Abstract: A vertical wave powered air compressor where different parts of the structure are at different depths (and hence static pressures). A plurality of compression stages are stacked one below the other. Each level has two or more chambers. The chambers have a series of check valves or water seals between them. Each passing wave raises and lowers the entire stack. As the stack moves downward, increased water pressure causes water to enter the first chambers at each level compressing the air inside. As the stack returns upward, the decreased water pressure causes water to leave the first chambers allowing the air therein to expand. However, the check valves prevent the air in the second chambers from expanding or escaping back into the first chambers. Another set of check valves allow the air in the second chambers, as it expands, to be forced downward into the next lower first chamber. With each upward and downward movement of the stack, as waves pass, a quantity of air moves downward from stage to stage until, at the bottom, the lowest stage discharges compressed air into a return pipe.

Abstract translation: 垂直波浪式空气压缩机，其结构的不同部分处于不同的深度（因此静态压力）。 多个压缩级彼此层叠。 每个级别都有两个或更多个房间。 这些腔室之间有一系列止回阀或水封。 每个通过的波都会提高和降低整个堆栈。 当堆栈向下移动时，增加的水压使水进入每个级别的第一室，压缩内部的空气。 当堆叠向上返回时，水压下降导致水离开第一室，允许其中的空气膨胀。 然而，止回阀防止第二腔室中的空气膨胀或逃逸回到第一腔室中。 另一组止回阀允许第二腔室中的空气膨胀时被迫向下进入下一个较低的第一腔室。 随着堆叠的每个向上和向下运动，随着波浪通过，一定量的空气从一个阶段向下移动到一个阶段，直到底部，最低阶段将压缩空气排放到回流管中。
