    Abstract: Separate pressure vessels for oxidizer and fuel components in a combustion/decomposition system add weight and complexity to the system. The fuel and oxidizer can be pre-mixed within a single pressure vessel, but can be unacceptably volatile in a mixed configuration. Providing separate fuel and oxidizer compartments within a singular pressure vessel reduces the weight and complexity of the system, while maintaining the non-volatility of separately stored fuel and oxidizer. The fuel and oxidizer can be selectively mixed within the pressure vessel when desired.

  • Patent number: 6386750
    Abstract: In a process for producing stable emulsions of at least two substantially immiscible fluids, particularly emulsions of a liquid fuel with water, a considerable increase in the efficiency of the emulsion-formation process is achieved by injecting the fluids to be emulsified into an emulsification chamber provided with an injection system which imparts to the fluids a motion in a direction which is substantially perpendicular to the general direction in which the fluids travel through the emulsification chamber. This injection system can be provided by means of a diffuser having an inlet hole, through which a stream of liquid is fed in a substantially axial direction, and at least one outlet hole, which leads into the chamber and whose axis lies on a plane which is substantially perpendicular to the direction of the inlet stream.

  • Publication number: 20010055242
    Abstract: A micro-electromechanical system and method for continuous laminar fluid mixing. An embodiment of the invention described in the specification includes a mixing channel, a first delivery channel that is connected to the mixing channel, and a second delivery channel that is connected to the mixing channel. A first pump mechanism produces pulses in the first delivery channel. A second pump mechanism produces pulses in the second delivery channel. The first pulsed fluid stream and the second pulsed fluid stream merge in the mixing channel to form a mixed fluid. The pulses in the fluids operate to distort the interface between the fluids to facilitate diffusion between the fluids.

  • Patent number: 6241378
    Abstract: The invention relates to a dosing apparatus for pastelike substances and mixtures thereof with a solvent by means of an injector, comprising an integrated shutoff device. The apparatus contains a detection device which detects the amount of paste according to conductimetry. The shutoff device is a dual piston valve closing an opening between the paste supply tube and an injector suction chamber as well as an opening between the solvent supply tube and an injector pre-chamber. The invention also relates to a method for dosing pastelike substances and the mixtures thereof with a solvent by means of such a device. By opening a shut-off device in a supply tube for a pressurized solvent, a dual piston valve moves against an opposing force. This releases a connection between a paste supply tube and an injection suction chamber, followed by a connection between the solvent supply tube and the injector pre-chamber.

  • Patent number: 6238081
    Abstract: An ultra-lean dilution apparatus is provided for proportioning minute quantities of a first fluid, such as a concentrated cleaning solution, for mixing into a second fluid, such as tap water, which provides improved performance and which can be manufactured by assembling several molded components with little or no machining. The dilution apparatus (20) provides a selective pressure drop in a conduit (22) by including a plurality of dilution disks (50a-50f), each dilution disk (50a-50f) having a tortuous path (52a-52f) of sufficient cross-sectional area to be resistant to clogging and having a sufficient number of sharp turns to create a desired pressure drop. While each disk (50a-50f) produces a predetermined drop, the serial configuration of the tortuous paths of the plurality of dilution disks is additive to produce a range of dilution suitable for the chemicals used.
