Granted: 2000-01-11
Abstract: A polyester preform which is injection molded preferably of PET and wherein the preform is provided with a molded neck finish or neck portion including threads which are molded to a high tolerance and wherein the neck finish may receive a closure cap of the type having a tamper indicating band which engages over a retaining bead also molded to a high tolerance as part of the neck finish. In order to maintain the container which is blow molded from the preform in axial alignment with the neck finish and thus eliminate the perpendicularity problem, a ring of the preform immediately below the flange which functions as the capping ring, is heated to a high temperature and crystallized. In a like manner, the end sealing surface is also heated to a high temperature and crystallized.      The remainder of the neck finish remains in its amorphous state without disturbing the configuration of either the threads or the retaining bead. This combination of crystallized portions with the remainder of the neck finish remaining amorphous assures a high quality connection between a closure cap, whether the closure cap is formed of plastic or metal, while providing the end sealing surface with a hard tough finish resisting deformation and at the same time reducing the closure cap removal torque.

La base des connaissances du système expert est constituée d'une hiérarchie de termes et de leurs définitions. Pour produire une réponse experte, une composante du système expert, à savoir un moteur d'inférence, évalue un terme en évaluant la totalité des définitions des termes qui se trouvent dans la hiérarchie de définitions de ce terme. Dans le système de création de documents, les termes incluent des termes fragmentaires qui sont définis comme des parties du document-type. D'autres termes de la base de connaissances peuvent apparaître à l'intérieur de cette partie. Le système de création de documents comporte une composante définition de termes qui, lorsque l'utilisateur définit un terme fragmentaire, fournit le programme d'édition à l'utilisateur de sorte que ce dernier peut écrire le fragment représenté par le terme fragmentaire. Une fois que l'utilisateur a défini le terme fragmentaire, la composante définition de termes ajoute le terme fragmentaire à la base de connaissances et vérifie que tous les autres termes de cette partie sont définis dans la base de connaissances. Dans la négative, l'utilisateur se voit demander une définition. Pour créer un document, le moteur d'inférence évalue un terme qui est défini selon un ou plusieurs termes fragmentaires. Lorsque l'évaluation indique qu'un terme fragmentaire doit être inclus dans le document, le moteur d'inférence utilise le programme d'édition pour retrouver tous les autres termes du fragment, évalue les autres termes, et ensuite utilise le programme d'édition pour transférer par copie, du document-type au document en cours de création, le texte du terme fragmentaire et pour remplacer par leurs valeurs les autres termes dans le document en cours de création.

Title: Genetic control of ethylene biosynthesis in plants
Inventor: FERRO ADOLPH J
IPC: C12N9/14
Filed: 1990-12-12
Granted: 2000-12-05
Abstract: A method for control of ethylene biosynthesis in plants composing a vector containing a selective gene under plant promoter control. and a DNA insert comprising codons for a functional heterologous polypeptide having AdoMetase activity and flanked by a plant promoter on one side and a polyA signal sequence on the other side; and, transforming a plant host with said vector wherein the plant host transformed thereby is capable of expressing the heterologous polypeptide having AdoMetase activity under the control of said control region. The presence and expression of AdoMetase in transgenic plants towers AdoMet levels and generates an inhibitor of ACC synthase causing a corresponding decrease in ethylene biosynthesis and precursor availability.  The current construction of transgenic plants containing a copy(s) of the T3 AdoMetase gene allow for construction of plants that will control ethylene biosynthesis resulting in fruits, vegetables, and flowers which have improved shelf life and preservation qualities.

Abstract: A method for authenticating communication participants, use a system for application of the method and first communication participant and second communication participant for application in the system.  Known methods for authenticating communication participants add a code word to a command signal, which code word is a cryptographic function of the command signal and a key value which in its turn is a function of a mater key value and a change code word. The master key value has a permanently fixed value, in contrast to the change code word which serves to change the key value.          The method according to the invention makes use of a key value which is a function of at least one previous key value, the master key value with the permanently fixed value, which, once it has been discovered or leaked, substantially weakens the encryption, no longer being required.
