Patent EP-0142010-B1 (EP)
IPC: C25D7/06
Filed: 1984-10-05
Granted: 1987-12-23
Abstract: The invention concerns a process for the electrodeposition of metals, especially zinc, on to metal strip, particularly steel strip, from an aqueous solution of the metal salts, using high relative flow velocities between electrolyte and strip and electrolyte and anodes, the metal strip being introduced vertically into the electrolyte, turned around and led vertically out of the electrolyte. A process of this nature should enable high current densities to be employed, including in vertical cells in which the metal strip, in particular steel strip, is passed vertically through the electrolyte, and permit even relative flows between the metal strip and the electrolyte, thus producing even deposition conditions for the parts of the metal strip entering and leaving the cell. The invention proposes that the electrolyte is forced to flow against the direction of strip travel throughout the section between the anodes and the metal strip. The equipment envisaged for carrying out the process is designed so that the electrolytic cell (1) is fitted with shaft-shaped sections (8, 12) for the strip entrance (8) and exit (12), within which sections (8, 12) the anodes (9, 11) are arranged parallel to each other and to the metal strip (6), and the sections (8, 12) are connected by a communicating lower part of the cell (13), and the top of the section (8) for the strip entrance is set lower than the top of the section (12) for the strip exit by the dimension  DELTA  h.

Title: Cementing tool for wells
IPC: E21B33/136
Filed: 1984-02-06
Granted: 1986-11-05
Abstract: A cementing tool for wells in a combination of a cementing or collar and a basket, comprising a sunstantially tubular mandrel (40) having a cement basket (170) disposed thereabout, the cement basket being maintained in a collapsed mode by an annular overshot (36) at the bottom of a coupling (26) at the top of the mandrel. A flapper valve assembly (80) is located within the mandrel, being maintained in an open mode by the presence of a fill-up tube (140) disposed in the valve orifice. The bottom of the fill-up tube is secured to a slidable ball seat (120) located below the flapper valve assembly. The ball seat is initially secured in place by attachment through a plurality of shear rods (150) to a tubular activating sleeve (160) disposed around the mandrel and under the cement basket, the activating sleeve being maintained in its initial position by contact with the bottom of the cement basket, which is fixed to the mandrel by a shear screw (174). To operate the apparatus, a tripping ball (not shown) is pumped down the casing to the ball seat, whereupon the casing pressure causes the basket shear screw, acted upon by the activating sleeve, to shear, the basket moving downward and out from under the coupling overshot. Continued application of pressure causes the activating sleeve shear rods to shear, allowing the ball seat to move to the bottom of the mandrel, and removing the fill-up tube from the flapper valve orifice, permitting the flapper to close.

IPC: A01H5/00

Granted: 1993-02-03
Abstract: This invention involves a cloning or expression vector comprising a gene which encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) polypeptide which, when expressed in a plant cell contains a chloroplast transit peptide which allows the polypeptide, or an enzymatically active portion thereof, to be transported from the cytoplasm of the plant cell into a chloroplast in the plant cell, and confers a substantial degree of glyphosate resistance upon the plant cell and plants regenerated therefrom. The EPSPS coding sequence may be ligated to a strong promoter, such as the 35S promoter from cauliflower mosaic virus, to create a chimeric gene. Such genes can be inserted into plant transformation vectors, and subsequently introduced into plant cells. Plant cells transformed using such genes and plants regenerated therefrom have been shown to exhibit a substantial degree of glyphosate resistance.

Granted: 1990-12-27
Abstract: Est décrit un nouveau dérivé stable de l'acide ascorbique, le 2-polyphosphate d'ascorbate, ainsi qu'un procédé de synthèse à rendement élevé de ce composé. Le procédé consiste de préférence à faire réagir un acide ascorbique tel qu'un acide L-ascorbique ou un dérivé de celui-ci tel que l'acide 5,6-O-isopropylidène-L-ascorbique avec des sels d'acide métaphosphorique dans un système aqueux et en présence d'une base suffisante pour maintenir le pH du mélange de réaction à un niveau au moins supérieur à 9 pour obtenir la 2-polyphosphorylation de l'acide ascorbique. Dans des formes particulièrement préférées, on fait réagir une mole d'acide L-ascorbique dans de l'eau avec entre 1,5 et 3 équivalents de trimétaphosphate de potassium ou de sodium à une température comprise entre 25 et 55oC, et un hydroxyde de métal alcalin tel que l'hydroxyde de potassium est ajouté par intermittence au mélange de réaction en fonction des besoins pendant une période de réaction comprise entre une heure et dix heures afin de maintenir le pH du mélange à un niveau compris entre environ 10,5 et 12 pendant toute la durée de la réaction. Après neutralisation, le mélange de réaction ne contient pas de substances nocives ou toxiques, et la totalité du mélange peut être ajoutée à des aliments ou aux fourrages. Des sels purs de 2-triphosphate d'ascorbate peuvent être isolés aisément en utilisant des techniques chromatographiques conventionnelles. On a également remarqué que les composés de l'invention s'oxydent plus difficilement, dégagent de l'acide ascorbique et sont hydrolisés plus lentement que le dérivé monophosphate de l'acide ascorbique.
