    Abstract: Gradient performance with high pressure gradient solvent delivery system is optimized by approximation of infinite stroke volume of high pressure pumps (105,122) by the addition of pulse dampening with backflow prevention to each high pressure pump (105, 122). The backflow prevention adds sufficient minimum flow resistance, thereby enhancing the performance of the pulse dampening over a wider range of flow rates -resulting in consistent gradient performance.

    Abstract: A flow controller having a first and second stages of regulation. The first stage is a pressure regulation stage that maintains the pressure within an intermediate chamber (formed by a series of interconnected passageways and cavities) within a predetermined range above the pressure in an outlet port. The second stage maintains the flow rate within a predetermined range about a target flow rate. Both stages sample the pressure in the outlet port and atomatically adjust the flow of fluid to ensure that fluctuations in pressure at the inlet and outlet ports do not affect the flow rate. The flow rate is set and controlled by a user determined setpoint. The flow rate is set and controlled by a user determined setpoint. The pressure is regulated by one or more feedback systems. The feedback systems used may be mechanical or electomechanical based on a particular operating environment.

    Abstract: A fluid control valve arrangement allowing very complex valve interconnection schemes to be implemented in a small volume is disclosed. The fluid control valve arrangement utilizes seat plates positioned above and below a block to allow creation of three layers of material between valve elements on opposite sides of the block. Since there are three layers of material between blister valve elements on opposite sides of the block, there are two interfaces on separate levels from those levels contacting valve membranes and blister recesses upon which to form interconnection channels. Because each side of the block has one layer allocated for blisters and another allocated for formation of interconnection channels, very complex valve interconnection schemes may be implemented in a small volume.

    Abstract: A valve apparatus (2) for selectively distributing the sequential passage of separate, organic fluids to a common receiver, such as a reaction vessel. The valve apparatus comprises a valve body member (16) having multiple openings (56) and a plurality of separate conduits (54) each communicating a fluid source with one of the openings. The body member also has a common passage (60) with circular groove portions (62) surrounding the openings so that fluid flows radially outward from the openings toward the common passage. A plurality of pistons (30) are individually reciprocable between first and second positions for controlling fluid flow between associated openings and the common passage. The invention also provides a system (100) and method for measuring and delivering a precise quantity of each of the organic fluids, e.g., chemical reagents, to the reaction vessel.

    Abstract: A safety connector for infusion therapy for several feeding lines has a housing (1) in which is arranged a chamber (4) delimited by a substantially cylindrical inner wall (5) of the housing, into which open several infusion line connecting channels (2) and which has an outflowing channel (9) for connecting to an outflowing line. An elastic and ring-shaped valve body lies with its cylindrical outer wall on the inner wall (5) of the housing which encloses the chamber (4). The cylindrical bearing surfaces between the ring-shaped valve body and the cylindrical inner wall (5) which encloses the chamber (4) ensure already at low bearing forces a high tightness of the nonreturn valves. The sealing force can be accurately determined down to very low pressures. A safety connector is thus for the first time created which is suitable for gravity infusion systems.

    Abstract: A method and apparatus for supplying dyes to a dyeing apparatus (30), dyes being selected to yield one of a group of colours. A plurality of tanks of dye (11-16) is provided, and a circuit leads from each tank to a selected one of a pair of valves (21, 22) that may either direct the dye to the dyeing apparatus (30) or direct the dye to be recirculated. The flow through each valve (21, 22) is metered so a particular rate of flow can be established. One group of the valves provides dye to the dyeing apparatus while another group of the valves (21, 22) recirculates dye to establish another color ready to be provided to the dyeing apparatus. The colors are defined in terms of the tanks (11-16) and rate of flow from the tanks, so a large group of colors can be defined and stored in a computer, and the computer can control valve position and pump speed to control the color produced by the dyeing apparatus.

    Abstract: In various embodiments, two or more electronic flow selectors of an electronic fluid flow control system may be used to control the flow rates of multiple fluids. In a total flow control mode, a first electronic flow selector may be used to select a total flow rate of two or more fluids. A second electronic flow selector may be used to select a flow rate or ratio of a flow rate of one fluid to the total flow rate of the two or more fluids. In a direct flow control mode, each electronic flow selector may be used to select a flow rate of a unique fluid. One of the fluids may be oxygen, and the other fluid, a balance gas, may be selected as either nitrous oxide or air using an electronic balance gas selector.
