IPC: G01N1/20
Filed: 1989-05-05
Abstract: Dans certaines installations de mélange ou de traitement, un dosage successif des matériaux provenant de diverses sorties de silo (8) est effectué en différents endroits d'une bascule à courroie ou à soute (2) et les échantillons de matériau sont prélevés aux sorties respectives. Pour un prélèvement d'échantillons automatique, il est très coûteux de prévoir des unités de prélèvement d'échantillons à chaque sortie, c'est pourquoi la présente invention utilise un échantillonneur unique (44) qui s'étend sur toute la largeur de la bascule réceptrice et qui est mobile longitudinalement le long de la bascule, de façon à pouvoir être placé en position de fonctionnement par rapport à n'importe laquelle des sorties. L'échantillonneur (44) est conçu de façon à pouvoir transférer, après chaque opération de prélèvement d'échantillon, l'échantillon prélevé vers un système transporteur pneumatique (20, 22) fonctionnant de façon à amener l'échantillon à une station d'analyse centrale. L'échantillonneur est conçu sous la forme d'une hélice transporteuse contenue dans un tube fendu (44), lequel peut être placé par rotation en position inactive, dans laquelle l'échantillonneur peut passer au travers d'un courant de matériau sans recueillir de matériau et dans laquelle il est vidé des restes d'échantillons précédents.

Abstract: A flexible stand (14) permits an instrument housing (10) or holster to which it is attached to be supported on a horizontal surface at any of a number of different viewing angles, to be hooked to a pipe or conduit, or to be suspended from a nail or the like. The stand (14) comprises a skeletal member that is formed of a pair of annealed cartridge brass wires separated from each other and maintained parallel by a pair of plastic !0 bridge members. The skeletal member is coated with thermoplastic polyester material, to form an assembly that is flexible, is non-brittle and exhibits substantially no mechanical memory so that it retains the shape to which the stand (14) is manually formed by the user. One end of the stand (14) is pivotally attached to the meter housing (10) or holster, and an abutment member on the stand (14) contacts a portion of the housing (10) or holster to prevent further pivoting when the stand is pivoted to a particular angle.

Abstract: A method is disclosed for the quantitative removal and concentration of desired transition metal ions from a source solution which may contain larger concentrations of other metal and H⁺ ions. The method comprises bringing the source solution into contact with a compound comprising a pyridine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The pyridine portions(s) of the compound has an affinity for the desired metal ions to form a complex thereby removing the desired metal ions from the source solution. The desired metal ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired metal ions than does the pyridine ligand portion of the compound. The concentrated metal ions thus removed may be recovered by known methods. The process is useful in removing unwanted metal ions from water streams and in the treatment of waste streams such as those containing metal ions from emulsions found in the treatment of photographic and x-ray films. The invention is also drawn to novel intermediates comprising pyridine containing ligands covalently bonded through a spacer grouping to a silane and to the final compounds formed by reacting the intermediates with a hydrophilic inorganic solid support material.
