    Abstract: Some embodiments relate to an apparatus for holding a workpiece under tension while one or more operations are performed on the workpiece, the apparatus comprising: a frame; a first spindle rotatably coupled to the frame; a first coupler configured to couple the first spindle to a first end of the workpiece; a second spindle rotatably coupled to the frame; and a second coupler configured to couple the second spindle to a second end of the workpiece; wherein a distance between the first and second couplers is adjustable to hold the workpiece under tension between the couplers while the one or more operations are performed, and wherein the workpiece can be rotated with the couplers relative to the frame about a common axis of rotation extending between the couplers. Some embodiments relate to a system comprising a controller for controlling rotation of the workpiece. Embodiments also relate to processes comprising holding a workpiece under tension while performing one or more operations on the workpiece. Some of the processes, systems and apparatuses described may be particularly useful for cold spraying delicate workpieces such as 3D printed static mixers.

    Abstract: An apparatus (100) for mixing a liquid (160) containing particulates (106, 108) comprising: a vessel (102) for containing the liquid (160) that includes a sidewall (120) and a bottom (124); and an impeller (300) rotating about a substantially vertical axis (X-X), said impeller (104): adapted for submerging below the liquid surface (162) by a distance that is approximately one-tenth to one-half of the height of the liquid (129); and include at least two annually spaced apart blades (310) extending radially outwardly of the vertical axis (X-X), the blades (310) comprising back-swept blades that are pitched substantially parallel to the vertical axis (X-X), at least 50% of the length of each blade (310) comprising an angled section (312) extending through a chord angle of 20 to 60 degrees; to produce (a) an inner, upward flow region (164) located along said vertical axis (X-X), (b) a transition flow region (166) located around the impeller (300) in which liquid moves radially outwardly toward the vessel sidewall (120), and (c) an outer, downward flow region (168) located along the sidewall (120).

    Abstract: A process for recovering phosphorus from phosphoritic materials in a top submerged lance furnace or a fuming furnace is disclosed. The process employs a mixture of combustion agents to produce reducing conditions in the slag bath and post-combustion oxidising conditions in the headspace of the furnace. The process involves smelting a mixture of a phosphoritic material and a carbonaceous material in the furnace to produce a molten slag in the slag bath and phosphorus vapour in the headspace, wherein the post-combustion oxidising conditions in the headspace favours retention of ferrous oxides in the molten slag to minimise deportment of phosphorus to a ferro-phosphorus alloy; The phosphorus vapour in the headspace is subsequently oxidised to produce phosphorus pentoxide, which is subsequently passed from the headspace to a reactor to recover a phosphoric acid solution.

    Abstract: The present disclosure is directed to the methods for identifying a combined corrosion inhibitor formulation comprising at least a first and second corrosion inhibitor formulation for inhibiting corrosion in various substrates, for example in metal substrates. The present disclosure is also directed to compositions for inhibiting corrosion comprising a combined corrosion inhibitor formulation each independently selected from organic heterocyclic compounds and metal salts, metal anions, metal complexes, or any combinations thereof selected from rare earth, alkali earth and transition metals.
