Title: Method for reproducing conifers by somatic embryogenesis using a maltose enriched maintenance medium
Inventor: GUPTA PRAMOD K
IPC: C12N5/00
Filed: 1996-04-10
Granted: 2001-12-11
Abstract: The invention is a method for reproducing coniferous trees by somatic embryogenesis using plant tissue culture techniques in a multistage culturin g process. A suitable explant, typically the fertilized embryo excised from an  immature seed, is first cultured on a medium that induces multiple early sta ge proembryos. These are multiplied in a second culture having reduced growth hormones. Maltose is supplied as the carbon and energy source in the second culture. Alternatively, a sucrose-containing maintenance and multiplication medium may be used followed by at least two subcultures on a maltose based maintenance medium. The early stage embryos grow in size and vigor to advanc ed early stage embryos. The embryos are then transferred to a cotyledonary embr yo development culture. After several weeks somatic embryos having the appearan ce of zygotic embryos will have formed. These may be germinated before or after  storage and transplanted to soil for further growth. Maltose used in the maintenance and multiplication culture results in larger and more robust advanced early stage embryos which, in turn, produce cotyledonary embryos ve ry similar in morphology to natural zygotic embryos. The use of maltose at earlier stages of embryo development is more important than its use for embr yo maturation.

Abstract: A lens adjustment device of a stereo camera of this invention operates adjustment rings of right and left lenses of an optical axis distance variable type stereo camera in the interlocking arrangement with each other. Crank arms are provided on stop adjustment rings of lenses mounted on the right and left lens boards capable of adjusting the distance between the optical axes.  The right and left crank arms are disposed in symmetry of rotation at 180°.      The center of a lever in a vertical direction is fitted to a shaft on a slide frame.  The upper end portion of the lever and one of the crank arms are interconnected by a link, while the lower end portion of the lever and the other crank arm are interconnected by another link.  When the distance between the optical axes of the right and left lenses is changed by an adjustment mechanism for adjusting the distance between the optical axes, the lever rotates while the stop adjustment rings are kept fixed.  When one of the stop adjustment rings is rotated either to the right or the left, the other adjustment ring, too, is rotated in the same direction and at the same angle through the links and the lever, so that stop adjustment of the right and left lenses operates in the interlocking arrangement irrespective of the change of the distance between the optical axes of these lenses.

Abstract: Air-atomizing induction-charging spray nozzles suited for use with conductive liquids, solutions, suspensions or emulsions. These systems feature a high level of spray charging at low induction-electrode voltage and current. Primary benefits include consistent, reliable operation in harsh agricultural and industrial environments with a wide range of spray formulations, especially those having relatively high concentrations of abrasive and conductive materials. The outer surfaces of the nozzles' body portion (1), near connections to earthed sprayer parts, are maintained floating or at near ground potential. The cover portion (2) surfaces adjacent to the induction electrode (18) are maintained at near the potential of the electro de (18). A highly resistive path between the high and low voltage portions of the nozzle is maintained and the electrode voltage or spray charge level doe s not decrease significantly as nozzle surfaces become coated with spray or are otherwise contaminated by conductive materials present in the spraying environment.

Abstract: L'invention porte sur un catalyseur de dénitrification, servant à réduire les oxydes d'azote présents dans des fumées contenant des sels fortement déliquescents tels que des poussières liées à de l'ammoniac et revêtus d'une couche poreuse faite d'un mélange d'une résine organique hydrophobe, et de particules de catalyseur. Le catalyseur de dénitrification peut par exemple se préparer en revêtant la surface d'un catalyseur de dénitrification avec une dispersion aqueuse d'une résine organique hydrophobe à faible concentration, puis en faisant sécher le revêtement de manière à former un revêtement poreux de résine organique hydrophobe. Ledit catalyseur de dénitrification même utilisé pour traiter des fumées riches en cendres contenant des sels fortement déliquescents empêche lesdits sels de traverser la couche poreuse hydrophobe pour atteindre le catalyseur. Cela évite la détérioration du catalyseur et permet de maintenir une forte activité catalytique sur une longue période.
