  • Patent number: 9981228
    Abstract: An apparatus for converting a dry material into a liquid concentrate includes a mixing vessel having an outlet opening, a dispenser for dispensing a predetermined weight of a dry material at a predetermined drop rate onto a predetermined drop location within the vessel, an inlet pipe connectable to a source of liquid for introducing a liquid into the vessel; a sensor for sensing the volume of liquid within the vessel; a pump for supplying a pressurized flow of recirculating liquid to the vessel; and a first, a second and a third agitating nozzle mounted within the vessel. Each agitating nozzle is operative to produce a jet of liquid oriented in a predetermined direction within the vessel. The nozzles are cooperable to generate within the vessel a moving body of liquid into which a dry material dispensed into the vessel is able to dissolve or to disperse.

  • Patent number: 9273336
    Abstract: Methods are provided to obtain recombinant microbial cells having at least one genetic modification that increase the buoyant density of a recombinant microbial cell or the buoyant density of inclusion bodies produced within a recombinant microbial cell. Exemplified are genetic modifications that increase the buoyant density of a recombinant microbial cell expressing heterologous peptides and polypeptides. Increasing expression of the genes ysaB, glyQ, glyS or a combination thereof within the recombinant microbial cell produces cells or inclusion bodies having higher buoyant density. A similar effect was achieved by decreasing or disrupting expression of the endogenous gltA gene. Increases in buoyant density render peptide production more efficient with respect to time and costs.

  • Publication number: 20160047061
    Abstract: A method for laying down a nanoweb of nanofibers from a centrifugal spinning process by a combination of an air flow field and a charging arrangement. Fibrous streams in the form of fibrils of molten polymer or polymer solution are discharged from a rotating member into an air flow field that is essentially parallel to the direction of discharge of fibrils at the point of discharge of the fibrils. The fibrous streams are attenuated and directed by means of the air flow field onto the surface of a collector to form a nanoweb. The fibrous streams are charged along all or at least a portion of their route from the point of discharge to the surface of the collector.
