Title: Process for separation and removal of iron ions from zinc oxide and basic zinc solution
Inventor: MARTIN VINCENT WISE
IPC: C01G9/02
Filed: 2001-09-07
Abstract: The present invention provides a process for the separation and removal of iron ions from a basic zinc solution. The process involves: treating an aqueous basic zinc solution with a solid ion exchange resin containing an insoluble cross-linke d polymer which contains at least one pendant phosphonate group, at a pH of from about  8 to about 12, and a temperature of from about 10.degree.C to about 90.degree.C, for a time period sufficient to form solid phase-bound iron ions and a liquid phase containing  the aqueous basic zinc solution having an iron ion concentration that is substantially reduced; separating the solid phase-bound iron ions and the liquid phase; an d treating the solid phase-bound iron ions with an aqueous acidic solution under conditions sufficient to regenerate the solid ion exchange resin. The present invention  also provides a process for preparing zinc oxide that is substantially free of ir on ions. This process involves: (a) treating ammonium carbonate and zinc oxide to form a mixture containing a zinc ammonia carbonate complex and metal impurities such as iro n, lead, and cadmium, and optionally sulfur; (b) optionally filtering the mixture fro m (a) to produce a residue containing mostly sulfur and a filtrate containing mostly the zinc ammonium carbonate complex and metal impurities containing iron, lead and cadmium; (c) treating the filtrate from (b), or the mixture from (a) with zinc(0) to remove the lead and cadmium and to form a cementation product, and filtering the cementation product to form a cementation residue containing mostly lead and cadmium and a cementation filtrate containing mostly zinc and iron ions; (d)  treating the cementation filtrate from (c) with the above mentioned ion exchange resi n, for a time period sufficient to form solid phase-bound iron ions and a liquid phas e containing the cementation filtrate having an iron ion concentration that is substantially reduced; (e) heating the liquid phase from (d) to remove ammonia and to precipitate zinc ions in solution as mostly zinc carbonate; and (f) calcining the zinc carbonate precipitate of step (e) at a temperature of from about 200.degree.C to about 1100.degree.C to convert the zinc carbonate to zinc oxide.

Abstract: A device for a braked movement of furniture doors in particular with a horizontal rotation axis comprises two attachment pieces (11, 12, 211, 212, 311, 312, 411, 412) that are movable in opposite directions around a common rotation axis (13, 213, 313, 413) in a free manner in one rotation direction and against a resisting force of a friction joint in the other rotation direction. Between an attachment piece and the friction joint the device comprises a first surface (28, 228, 328, 428) and a second surface (27, 227, 327, 427) facing each other to delimit a space therebetween in which a wedging element (26, 226, 326, 426) is disposed. The extension of the facing surfaces and/or the shape of the wedging element between them are of such a nature that the wedging element tends to fixedly fit between said facing surfaces causing them to rotate integrally with each other when rotation of the two attachment pieces takes place in the direction that must involve a braked movement.

The sintering temperature in the sintering step is located within a range of 800°C or higher and 900°C or lower.  Accordingly. even when manganese which is inexpensive and abundant in resources is employed as a main material, an excellent cathode performance can be maintained under the environment.

Title: Contour forming of metals by laser peening
Inventor: HACKEL LLOYD
IPC: B23K26/352
Filed: 2000-06-26
Abstract: A method and apparatus are provided for forming shapes and contours in metal  sections by generating laser induced compressive stress on the surface of th e metal workpiece. The laser process can generate deep compressive stresses to  shape even thick components without inducing unwanted tensile stress at the metal surface. The precision of the laser-induced stress enables exact prediction and subsequent contouring of parts. A light beam of 10 to 100 J/pulse is imaged to create an energy fluence of 60 to 200 J/cm2 on an absorptive layer applied over a metal surface. A tamping layer of water is flowed over the absorptive layer. The absorption of laser light causes a plasma to form and consequently creates a shock wave that induces a deep residual compressive stress into the metal. The metal responds to this residual stress by bending.

Title: Generation d'une clef mathematiquement contrainte a l'aide d'une fonction univoque
Inventor: SPRUNK ERIC J
IPC: H04L9/30
Filed: 2000-11-22
Abstract: L'invention concerne une clef cryptographique (K2) générée à l'aide d'une fonction univoque (325). Selon l'invention, on procède à un test pour satisfaire à une contrainte mathématique. Dans un codeur (200, 200'), tel une tête de station ou un site de production, on obtient des données de pré-encemencement par la subdivision (320) d'une chaîne de bits aléatoire en plusieurs segments (PRE-P1, ..., PRE-P8, PRE-Q1, ..., PRE-Q8) puis par le traitement isolé de chaque segment par une fonction univoque (325) pour obtenir des valeurs respectives (P, Q). On teste ces valeurs (P, Q) pour savoir si elles satisfont à une contrainte mathématique telle qu'un caractère premier (345). Si les valeurs échouent au test, les opérations sont répétées. Si elles valeurs passent le test avec succès, un module N (350) et l'indicateur d'Euler .phi. = (P-1) (Q-1) (355) sont formés. Les segments pré-K1-1, ..., pré-K1-16 sont également traités par une fonction univoque pour obtenir des segments K1-1, ..., K1-16, qui sont assemblés pour donner une valeur K1. On utilise l'algorithme basique euclidien (360) pour déterminer si K1 est relativement premier à .phi.:. Si ce n'est pas le cas, un nouveau K1 est formé. Si c'est le cas, une clef (K2) est formée à partir de l'algorithme étendu euclidien (365) pour le codage des données. Dans un décodeur (260, 260'), les données de pré-enscemencement sont fournies, notamment via une puce, et traitées à l'aide de la même fonction univoque (615) que celle utilisée dans le codeur pour obtenir le module N et la clef K1 destinés à être utilisés dans le décodage des données codées.
