Abstract: L'invention concerne un système de guidage par radar à impulsions (10) et un procédé (30) d'utilisation avec un projectile à giration (11). Le système et le procédé suivent le vol du projectile à giration au moyen d'un radar tout temps (14) ou d'un dispositif de poursuite (14). Une forme d'onde asymétrique polarisée linéairement (21) est transmise au projectile qui comprend une série d'impulsions de répétition (22) ayant une impulsion de champ électrique positive, courte, relativement forte (23) suivie par une ligne de base à champ électrique négatif, long, relativement faible (24). Le projectile renferme une antenne dipôle (26) ayant une diode de commutation (27) entre ses moitiés respectives. La forme d'onde est réfléchie par l'antenne, laquelle tourne avec le projectile et renvoie un signal relativement fort, lorsque l'impulsion de champ électrique de la forme d'onde asymétrique est alignée le long d'une direction de conduction de la diode, un signal réfléchi relativement faible, lorsque l'antenne et la diode sont alignées orthogonalement à l'impulsion de champ électrique, et un signal faible, non nul, lorsque la diode est alignée antiparallèle à l'impulsion de champ électrique et lorsque la diode est polarisée en retour de telle façon que les moitiés respectives de l'antenne soient déconnectées. Le radar ou le dispositif de poursuite mesure l'angle de roulis instantané du projectile à giration durant son vol, en fonction de l'état du signal réfléchi.

Title: Method and arrangement for computing and regulation of the distribution of linear load in a multi-nip calender and a multi-nip calender

Filed: 1998-05-07
Granted: 2008-10-07
Abstract: The invention concerns a method and an arrangement for computing and regulation of the distribution of linear load in a multi-nip calender. The material web (W) is passed through the nips (N1...N9) in the set of rolls (12), which set of rolls comprises a variable-crown upper roll (13), a variable-crown lower roll (14) and intermediate rolls (15...22) fitted between the upper and lower rolls (13, 14). All the rolls in the set of rolls are supported so that, when the nips (N1...N9) are closed, the bending lines of the rolls are curved downwards. In the computing and regulation of linear loads, the physical properties affecting the bending of each intermediate roll (15...22) under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls (15...22), the own weight of the rolls, and of the support forces applied to the rolls is regulated so that the set of rolls is in a state of equilibrium and in a predetermined state of deflection. The invention also concerns a multi-nip calender that carries out the method.

Abstract: This invention relates to methods for producing transgenic plants that contain a gene of interest and that are free of foreign ancillary nucleic acids. These methods allow for the production of plants which thus contain a desired gene, but which are free of vector sequences and/or marker sequences used to transform the plant. The method of transforming such plant calls for transforming the plants with a gene of interest by introduction of the gene on a DNA construct comprising a transposon and foreign ancillary nucleic acids; crossing the transformed plant through self-crossing or with another plant to obtain Fi or more removed generation progeny; and utilizing a means for selecting those progeny that carry the gene of interest and are free of the ancillary nucleic acids. Such progeny may be detected biochemically, by Southern hybridization, through the use of polymerase chain reaction procedures and other methods available in the art.
