Abstract: A volumetric mixer is provided including a holding section adapted to store one or more materials simultaneously, one or more conveyors disposed in the holding section, a mixing section, one or more heating units disposed in the mixing section, and a control unit. The conveyors are operable to convey materials from the holding section to the mixing section and the one or more conveyors are operable to be individually controlled by the control unit to deliver a pre-determined amount of each material from the holding section to the mixing section.

Abstract: The present invention relates generally to compounds providing antibacterial therapeutic agents and preparations, and related methods of using and making antibacterial compounds. Antibacterial compounds of the present invention include chalcone, alkylpyrimidine, aminopyrimidine and cyanopyridine compounds and derivatives thereof exhibiting minimum inhibitory concentrations (MIC) similar to or less than conventional antibacterial compounds in wide use. For example, the present invention provides chalcone and cyanopyridine compounds, and derivatives thereof, exhibiting high antibacterial activities having multiple electron withdrawing group substituents, such as halogens and fluorinated alky groups, and optionally having hydroxyl and/or alkoxyl groups substituents.
