Abstract: There is described a method of preparing solid particles of a material, said method comprising controlling provision of a first liquid phase, wherein said first liquid phase comprises a solution of a first material through a membrane, said membrane defining a plurality of pores; and controlling provision of a second liquid phase, wherein said second liquid phase comprises a solution of a second material; reacting the first a second materials to produce a third liquid phase comprising a solution of a third material; and supersaturating the third liquid phase to form solid particles of the third material.

Abstract: There is described a method of preparing solid particles of a compound, said method comprising controlling provision of a liquid phase, wherein said liquid phase comprises a solution of the compound, in a first flow direction to a membrane, said membrane defining a plurality of pores; and controlling the supersaturation of the liquid phase after it has passed through the membrane via the plurality of pores, to form solid particles of the compound. The method may comprise a continuous method.

Abstract: This written description uses examples to disclose the invention, including the best mode, and also to enable one of ordinary skill in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that are not different from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.

Abstract: A virtual reality welding process and system is described which includes a programmable processor based subsystem, a spatial tracker operatively connected to the programmable processor based subsystem, a mock welding tool capable of being spatially tracked by the spatial tracker in which the mock welding tool includes two or more adapters. Each adapter emulates the real-world appearance of a particular weld type and interfaces with a base that is removably coupled to each of the two or more adapters. The base has one or more sensors to determine spatial location relative to the spatial tracker. The programmable processor based subsystem executes an appropriate instruction set associated with each adapter to render a display to the user on a face-mounted display device commensurate for each of the two or more adapters.

Abstract: A simulator for skill-oriented training is presented. The simulator includes a platform having a sensor and provides an immersive virtual training environment. The simulator includes a display unit worn by the operator. The unit includes a camera, a speaker and a unit sensor. The camera and the speaker provide visual and audio output to the operator. The simulator includes a controller and a data processing system. The controller includes a sensor. The sensors cooperate to provide to the processing system signals representing spatial positioning, angular orientation and movement data of the controller relative to the platform and a work piece. In response, the processing system renders the work piece, a virtual coating spray pattern, a virtual coating as applied to the work piece and performance guidance in the training environment.
