Title: Method for chemical extraction of metals by treatment of industrial waste and modular plant for the implementation of the method thereof
Inventor: MINCHEV EMIL
IPC: C22B19/30
Filed: 2018-03-22
Abstract: The present invention application relates to a modular plant for chemical and metallurgical processing of industrial waste such as steel powders, filter dusts, sludges, insoluble residue resulting from the extraction, sludges, drosses, sinters, slags, etc. performed by pyrometallurgical and hydrometallurgical processes until production of intermediate and end products such as zinc, zinc dust, zinc alloys, zinc sulphate salt, copper sulfate crystals, copper insoluble residue resulting from the extraction for copper and copper products, lead insoluble residue resulting from the extraction, cadmium, tellurium, gold, silver, etc. The method for chemical (metallurgical) metal extraction of industrial waste includes the following steps: preparation of the charge from secondary industrial waste, activating agents and carbon-containing reductant by mixing, granulation and wetting, after which the charge is fed into a tubular waelz kiln. This is followed by waelz process, cooling and filtering the kiln gases. The metals from the charge Zn, Pb, Cd are reduced, evaporated and oxidized by the air flow, which moves in counterflow to the charge, whereby the exhaust gases containing oxides of Zn, Pb, Cd are cooled and purified in a filtering module. The purified gases are released into the atmosphere, and the waelz oxides caught in hose pipe filters after transportation and granulation, enter for oxidative frying at a temperature of 900oC in a frying tube rotary kiln. From the upper end of the kiln are removed secondary waelz oxides rich in Cl, F, Cd, Pb, Se, Te, Tl and As, and from the lower end of the kiln are separated fried waelz oxides, from where by means of transport system they are transported to a collecting vessel, after that they are subjected to triple aqueous alkaline washing until the metal oxides of Cl, F, Se are purified. It follows the stage of Zn and Cd extraction. The purification from Sb, Ge, As and Fe is carried out through the processes of neutralization to pH = 4.8 -5, oxidation, hydrolysis, precipitation and filtration, and for purification from Se, Te and Tl are applied the processes of neutralization to pH 4.8 -5.2, with subsequent precipitation, cementation, as the purified zinc sulphate solution enters the basic zinc production scheme, and salts or zinc sulphate solution are obtained from the resulted solid residue. According to the invention is designed a modular plant for chemical extraction of metals by processing industrial waste and consists of a receiving storehouse for secondary industrial waste, activators and a solid reductant, a charge preparation section, a tubular waelz kiln for reducing roasting of the charge and a section for quicksand to separate the clinker from the unreacted reductant (coke), which are connected in series.

Abstract: Beim aerodynamisch optimierten Propeller zur Reduzierung der Lärmemissionen und gleichzeitigen Leistungssteigerung handelt es sich um einen Propeller mit zwei oder mehr Blatt – anwendbar für Flächenflugzeuge, Helikopter oder Schiffe – bei dem jedes Blatt mit einem abströmkantenseitigen, schlitzförmigen Durchbruch (1) ausgerüstet ist, der in Längsrichtung des Propellerblatts und parallel zur Abströmkante (3) verläuft, in Kombination mit einer Blattkürzung durch eine radial abgeflachte Blattspitze als Endfläche (10) und einer daran fixierten Endscheibe (2). Die Blattkürzung verringert die Blattspitzengeschwindigkeit und damit die Lärmemissionen; die Endscheibe (2) entschärft die Wirbelbildung. Die Leistungseinbusse infolge der Blattkürzung wird wettgemacht oder überkompensiert mit dem schlitzförmigen Durchbruch (1), wodurch (Fig. 4 ) ein Durchströmkanal (1) und ein Nebenprofil entsteht, welches durch zusätzliche Strömungsbeschleunigung die üblichen Wirbel über dem hinteren Teil des Hauptprofils glättet, dadurch die Vortriebsfläche, den Vortrieb und den Wirkungsgrad vergrössert und damit die Propellerleistung steigert.

Abstract: Pour déterminer un spectre intrinsèque à partir d'un spectre mesuré à l'aide de l'algorithme d'entropie maximale, il est difficile ou pas pratique du tout de déterminer les valeurs propres d'une matrice NxN de grandes dimensions (N de l'ordre de 104 à 105). Selon l'invention une telle grande matrice est subdivisée en un grand nombre de matrices partielles beaucoup plus petites, lesquelles sont situées sur la diagonale ou le tracé de la grande matrice. L'ensemble des valeurs propres à déterminer regroupe alors toutes les valeurs propres des matrices partielles pouvant être déterminées beaucoup plus vite. Etant donné le caractère de type Toeplitz des matrices partielles, leurs valeurs propres peuvent être déterminées très vite par transformation de Fourier d'une seule rangée d'une telle matrice. A l'aide de l'ensemble des valeurs propres ainsi obtenues, le spectre intrinsèque est déterminé au moyen d'un algorithme de minimisation. Le taux de convergence de l'algorithme de minimisation peut être fortement augmenté par addition d'une valeur de bruit aléatoire aux variables du processus de minimisation et par diminution de cette valeur de bruit jusqu'à zéro en un certain nombre de pas d'itération.

Abstract: The present invention provides a method and a NAND-type flash memory device. The method includes forming a select gate oxide layer in a select transistor area of a substrate and a tunnel oxide layer in a memory cell area of the substrate; forming a doped amorphous silicon layer on the select gate oxide layer and the tunnel oxide layer, the doped amorphous silicon layer having a dopant level which simultaneously avoids a select transistor word line high resistance problem and a charge gain/charge loss problem; forming an insulating layer on the doped amorphous silicon layer; forming a control gate layer on the insulating layer; and etching at least the doped amorphous silicon layer, the insulating layer, and the control gate layer to form at least one memory cell stack structure and at least one select transistor stack structure. In a preferred embodiment, the polysilicon layer which forms both the floating gate of the flash memory cell and the select gate of the select transistor of the device is doped with between approximately 5x1018 and 8x1019 ions/cm3 of phosphorus. With this dopant level, the contact resistance of the select transistor's control gate is low, thus keeping the word line resistivity of the device low. Simultaneously, contamination of the tunnel oxide of the flash memory cell by the dopant is limited, allowing for the interface between the floating gate and the tunnel oxide to be smooth, which prevents charge gain/loss problems. Thus, the reliability of the device is increased.
