Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose especial problems. Existing proposals to use acidic hydrogen peroxide to oxides and solubilize tungsten is extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention, hydrogen peroxide can be used considerably more efficiently in the extraction of tungsten into an aqueous acidic solution by employing certain promoters which are solid at 50 DEG  C. in the form of fused blocks. These blocks release the promoter slowly into the reaction solution and achieve similar efficiency of use of hydrogen peroxide and acid but at markedly reduced consumption of promoter in comparison with the same promoter added in powder or granular form. Examples of such promoter are hydroxy or amino substituted aromatic carboxylic acids e.g. 2-hydroxybenzoic acid. The promoters can most conveniently be used in a multi-stage tungsten extraction process.

Title: Reduction of nitrogen-based pollutants through the use of urea solutions containing oxygenated hydrocarbon solvents.
Inventor: BOWERS WAYNE E
IPC: C01B21/00
Filed: 1986-10-03
Abstract: Disclosed is a process for maintaining low effluent ammonia contents while reducing nitrogen oxides in an effluent from the combustion of a carbonaceous fuel under oxygen-rich conditions which minimize the production of carbon-based pollutants. An aqueous solution of urea and an oxygenated hydrocarbon is injected into an effluent at a temperature above 1600 DEG  F., and preferably above 2000 DEG  F. The oxygenated hydrocarbon will be employed at a level effective to reduce the levels of free ammonia in the effluent. This is important when burning fuels containing significant sulfur contents because the free ammonia tends to react with the sulfur compounds to produce solid ammonium sulfate and/or bisulfate which can decrease boiler efficiency.

Abstract: In a sheet feed bench with two parallel sheet feed rails that are adjustable relative to one another and with each having blowing jets on their surfaces facing one another directly above the level of the bench, connected to a common source of compressed air, the sheet feed rails resting on the bench surface are provided with groove-like or notch-like enlargements at the level of the blowing jets. Each of these extend over the entire length of the sheet feeder rails. These enlargements make it possible to position the inner surfaces of the sheet feeder rails so closely and tightly against the longitudinal edges of the stack of sheets that only small amounts of compressed air can escape upward. The formation of an air cushion is improved by this in such a way that the stack height can be more than double without adversely affecting the single-sheet separation.

Abstract: Un réseau de photodiodes HgCdTe pour la détection d'un rayonnement à infrarouge à longueur d'onde moyenne possède une structure stratifiée consistant en un substrat, une couche tampon à large intervalle de bande fortement dopée, et une couche de base à intervalle de bande étroit légèrement dopée. Deux ensembles de rainures en forme de U disposées orthogonalement sont réalisés par attaque chimique complètement au travers de la couche de base et partiellement au travers de la couche tampon, formant ainsi une pluralité de structures en forme de mésa. Sur une portion de la couche de base contenue dans chaque mésa se trouve une couche de recouvrement de conductivité opposée. La jonction de la couche de base et de la couche de recouvrement dans chaque mésa forme une photodiode. Une zone de métallisation est en contact avec chaque couche de recouvrement pour assurer la connexion de la diode sous-jacente à un dispositif de lecture. Une autre couche de métallisation est en contact avec la couche tampon pour former une connexion électrique commune au réseau de photodiodes. Une couche de passivation contenant une charge positive fixe est déposée sur les surfaces des mésas. La charge crée une couche d'inversion dans la surface de la couche de base exposée le long des parois des mésas, élargissant ainsi la jonction p-n de chaque photodiode. Un rayonnement frappant une surface inférieure du substrat transparent passe au travers du substrat et entre dans la couche tampon qui est également transparente. Le rayonnement transmis au travers de la couche tampon est absorbé dans la partie de la couche de base contenue dans chaque mésa, ce qui a pour résultat de produire des courants de diode.
