    摘要: A variable residence time chamber module that provides an additional residence time for a reaction of mixed reactants to reach completion. The module includes a thermally insulated housing in which are disposed a plurality of residence time chambers. A rotary inlet valve and rotary outlet valve select among the plurality of chambers, coupling them respectively to an inlet port through which the mixed but incompletely reacted reactants are supplied and an outlet port through which a desired product of the reaction is withdrawn. A heat transfer media is preferably used to control the temperature of the residence time chambers, so that an optimal reaction temperature is provided. The mixed reactants pass through the inlet valve into a selected one of the plurality of residence time chambers. Once the selected residence time chamber is full, the inlet valve is actuated to supply the mixed reactants to a successive residence time chamber. After the reactants in a filled residence time chamber have completely reacted to form the desired product, the outlet valve is actuated to withdraw the desired product. Because a plurality of different residence time chambers are provided, it is possible for the module to be used with a chemical processing system that produces different products in sequence. Each of the residence time chambers can be filled with a different mixture of reactants. It is then preferable that the valves and empty residence time chambers be flushed with solvent to ensure that no cross-reactions and no contamination occurs among different reactants/products.

    摘要: A method and apparatus for forming a stream of molten material. The apparatus includes a melt container having a bottom wall in which is formed an aperture. A funnel is adapted and constructed to receive molten material from the aperture in the container, and includes a plurality of fluid-cooled metallic segments. The funnel segments define an inner funnel contour that decreases in cross-sectional area from the inlet end to the outlet end of the funnel. An electrically conductive coil surrounds the funnel, and has a shape corresponding to the outer shape of said funnel. A source of medium-frequency current in selective electrical connection with the coil. The method begins with the step of providing a predetermined quantity of molten material in a melt container. A metallic funnel is provided in fluid communication with the melt container, and includes a plurality of fluid-cooled funnel segments. The method also includes the step of providing an electrically conductive coil surrounding the funnel. When molten material flows from the melt container through the funnel, AC current is passed through the coil at an intensity sufficient to heat the molten material flowing through the funnel.

    摘要: A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved. Different reactor designs, having additional reactant pathways, more or fewer heat transfer fluid pathways, more or fewer heat exchangers, more or fewer mixing chambers, more of fewer reaction chambers, and more or fewer sensor pathways can readily be achieved by adding or removing plates from the stack, and or by changing the pattern and number of openings in the simple plates that are used. The simple plates can be field in the stack during use of the chemical reactor using pressure exerted on opposite outer simple plates of the stack, or can be permanently joined. A preferred material for the fabrication of the plates is stainless steel, although other materials such as glass, plastic, and other metals can alternatively be used, which are compatible with the selected reactants and the desired product.

    摘要: An automated sequential reaction system that can be used to either sequentially produce a plurality of different products each requiring a single reaction, or to produce a desired product that requires a series of sequential reactions. A system controller controls an automated reactant supply, a solvent supply, a reaction module, a detector, and a product collector. Prior to initiating any reaction, the system is flushed with solvent and a heat exchanger supplies the reaction module with a temperature-conditioned fluid to maintain the reaction module at a desired temperature. For single reactions, a plurality of reactants are injected into a chemical reactor included in the reaction module. As fluid exits the chemical reactor, the detector determines if the fluid is a desired chemical product or solvent, and routes the fluid to the appropriate receptacle. Once a predetermined volume of a desired product is obtained, the system is flushed with solvent, and a different set of reactants are injected into the chemical reactor to produce the next desired product. The process is repeated until a substance library of the desired products is obtained. For products requiring sequential reaction steps, either a plurality of reactors are employed, or an intermediate product produced by a previous reaction is reintroduced into the reaction module with an appropriate reactant to complete the next sequential reaction.

    摘要: An automated vehicle suspension system includes an elongated and linear drive axle having opposed end portions pivotally connected to a selected portion of a vehicle and laterally extending outwardly therefrom respectively. The system further includes a mechanism for detecting uneven road surfaces. The detecting mechanism is coupled to the drive axle and housed proximate to a vehicle's wheel. The system further includes a mechanism for automatically articulating the wheel about the drive axle such that the wheel can be selectively raised and lowered from equilibrium to offset an impact force associated with the uneven road surfaces when the vehicle travels thereover during driving conditions. A wheel hub interface is laterally secured to the detecting mechanism such that the drive axle can be maintained at a substantially stable position. A wheel mount is threadably coupled to one end portion of the drive axle and outwardly spaced from the wheel hub interface.

    摘要: A modular chemical production system that preferably includes a microreactor for producing a product by reacting two or more reactants. Modularization enables components such as controllers, pumps, valves, microreactors, and processing modules to be added or removed from the system as required to produce a desired product. A minimum system includes a control module and a reaction module, which has a mixing volume and a reaction volume. Various pumping modules and residence time modules may also be included in the system. Modules can be changed if malfunctioning, or for producing a different product, or to change a quantity of the chemical produced. The control module preferably accesses a database in which data define parameters for a plurality of different reactions that are optimized for the production of different chemical products. The user selects the product desired and the amount of the product, provides the reactants, solvents, and heat transfer media supplies, and the control module operates the system to automatically produce the product until the desired amount is obtained. The reaction module preferably includes a microreactor, which can be replaced with a microreactor of a different configuration to produce a different product. Connections between modules are designed to enable quick connection and disconnection of modules, and fluid lines are self sealing to prevent leakage of fluids when changing modules.
