    Abstract: An apparatus and method for synthesis and screening of materials are disclosed. According to one aspect of the present invention, a parallel batch reactor for effecting chemical reactions includes a pressure chamber, an inlet port, two or more reaction vessels within the pressure chamber, and a reaction vessel cover. The inlet port is in fluid communication with the pressure chamber, and pressurizes the pressure chamber from an external pressure source. Each of the two or more reaction vessels are in isolatable fluid communication with the pressure chamber such that during a first pressurizing stage of operation, each of the two or more reaction vessels can be simultaneously pressurized through common fluid communication with the pressure chamber. In addition, during at least a second reaction stage of operation, each of the two or more pressurized reaction vessels can be isolated from each other by positioning the reaction vessel cover appropriately.

    Abstract: A method of optimising a reaction in a microreactor. Two reaction fluids A, B as supplied to a microchannel 6 and their relative proportions are varied in a controlled manner. A sensor 13 monitors a reaction characteristic and determines the relative proportion of the fluids which optimises the yield of the reaction product. The total flow rate can also be varied at the optimum relative proportion in order to determine the maximum overall flow rate at which completion of the reactions still occurs.

    Abstract: The general purpose of this invention is to provide an improved apparatus and method of preserving the vulnerable area of a railroad cross tie near the interface of the tie and the tie plate. To attain this purpose the invention provides a thin preservative-bearing gelatinous material that is placed between the cross tie and the tie plate either at the time of the original laying of rail or during any subsequent relaying. No extra equipment is needed and only a negligible amount of labor is required to simply place the gelatinous material on the adzed surface of the cross tie prior to the mounting or remounting of the rail. The presence of the gelatinous material poses absolutely no resistance to the subsequent driving of the spikes into the tie and is thin enough so as not to pose any rail alignment problems. The use of the gelatinous material relies on the moisture found under the tie plate to leach the active ingredients out of the material and help diffuse them throughout the adjacent section of wood. In addition, the unloading and loading of the tie plate by the passing of a train forces moisture into and out of the gelatinous material to further promote the leaching action. The inert components of the gelatinous material are completely biodegradable and will not pose an environmental problem at the end of the material's service life.

    Abstract: Apparatus and method for sequential injection liquid-liquid extraction analysis. Under the control of a bidirectional precision pump, a stream-selection valve, and a microprocessor, a series of liquid zones is built up in a holding/mixing coil. The liquid zones are transferred from the holding/mixing coil to a separation cell. After phase separation into an extract and a raffinate, the extract is withdrawn from the separation cell and sent to a detector, which determines the amount of a component which was extracted from a sample by an extraction solvent. The principal advantages of this automated technology are elimination of the need for dynamic phase separation; on-line pre-extraction chemical conditioning; a substantial reduction in solvent, reagent, and sample usage; and a similar substantial reduction in waste generation.
