Abstract: A powder hopper is provided with a low turbulence zone for supplying powder to a spray gun. The low turbulence zone is defined by a baffle inside the hopper with the low turbulence zone being within a volume of the baffle, and an annular zone between the baffle and the hopper is used to bulk feed powder into the hopper. The low turbulence zone may alternatively be in the annular zone with powder added to the volume of the baffle. One preferred application for this hopper is in connection with the use of fine powder coating materials to coat the interior of small diameter cans.

Abstract: Boron compounds are separated and recovered from a geothermal brine, which additionally contains inorganic salts, such as sodium and potassium chlorides and sulphates, by means of a process comprising the following process steps:(a) pre-concentration of the geothermal brine by expansion up to room pressure, to a pressure lower than room pressure;(b) concentration of the pre-concentrated brine, coming from the (a) step, by means of an osmotic treatment against a concentrated aqueous solution of recycled inorganic salts;(c) treatment of crystallization of the concentrated brine, coming from the (b) step, with the separation of the solid inorganic salts from an aqueous solution of boron compounds;(d) recycle of the inorganic salts separated in the (c) step, to the (b) step of osmosis, in the form of a concentrated aqueous solution; and(e) recovery of boron compounds from the relevant aqueous solution obtained in the (c) step.
