Abstract: The present invention is a novel gas assisted nozzle and a method for micro and nanofiber production. In this composite nozzle, a high velocity gas stream is introduced through a core protruding orifice, while a liquid is introduced via at least one satellite orifice, external to the core orifice. The liquid flow is picked-up and accelerated (blown) by the gas stream from the tip of the protruding gas nozzle. This avoids passing the high velocity gas over the surface of the slow flowing liquid and achieves the acceleration of the liquid flow on its approach to being picked-up by the gas stream. Proper control of the gas and the polymer liquid flow results in fine liquid blowing and formation of micro and nanofibers.

Abstract: Prepackaged reagent reservoirs with associated nozzles allow for accurate, repeatable distribution of reagents in various types of reactions, reducing the risk of human error. Series of reservoirs may be arrayed on a sheet or plane for automated manipulation providing a simply format for organizing, storing, transporting, and distributing reagents needed in complex reactions such as those in the molecular biology field.

Abstract: A process for making a mould piece having a main curved surface bearing an utilitary microstructure which comprises transferring a utilitary microstructure from a master piece main surface to a main surface of a flat cured elastomeric film; pressing the cured elastomeric film and a master article against each other so as to conform the overall shape of said cured elastomeric film to the curved shape of the main surface of the master article and to spread over a curable coating composition between the curved main surface of the master article and the main surface bearing the replica of the said utilitary microstructure of the cured elastomeric film; curing the coating composition; removing the cured elastomeric film and depositing a layer of a metal or a metallic alloy on the exposed main surface of the hard coating of the master article; and recovering said metal or metallic alloy layer to obtain a mould piece having a curved main surface bearing a replica of said transferred utilitary microstructure.

Abstract: A late select circuit topology has pseudo-static circuits that provide fast dynamic circuit operation without the use of dynamic clock timing signals. An output from a selected set is enabled by the conjunction of bit line pulse and set select signal.

Abstract: A SRAM sense amplifier timing circuit provides various delay settings for the sense amplifier enable signal (sae) and the sense amplifier reset signal (rse) in order to allow critical timing adjustments to be made for early mode, late mode conditions by varying the timing or with of the sense amplifier output pulse. These timing adjustments are programmable using scan in bits.
