Abstract: The invention relates to a method for arranging conveyor-transported fragmentary particles into one row or several adjacent rows of individual particles before their removal from the conveyor. According to the invention, the conveying base is divided into two subsequent sections, namely, a vibrating section and a subsequent stabilizing section. In the vibrating section the conveying base and the particles on top of it are brought into a relative motion while the particles are subjected to transversal counter-forces in order to concentrate the particles along a straight line in the longitudinal direction of the conveying base. In the stabilizing section the relative motion of the conveying base and the particles on top of it is stopped in good time before the removal of the particles from the conveyor, so that the particles no longer move in relation to each other when they are being removed from the conveyor. This substantially facilitates the analysis of the particles and their separation from each other.

Abstract: An apparatus for the vaporization of elemental sulfur by means of carrier gas, the apparatus comprising a first thermally insulated vessel for the melting of elemental sulfur, provided with a heating means, a stirrer and an inlet pipe for elemental sulfur, and at least one second vessel inside the first vessel and communicating vessel with it, and provided with heating means, a stirrer, means for feeding carrier gas and an outlet pipe for sulfur vapors, and optionally also provided with thermal insulation, for vaporizing the molten elemental sulfur flowing from the former vessel by means of carrier gas.
