Filed: 1993-09-27
Granted: 1998-04-28
Abstract: The invention relates to a wide area network implemented on a circuit-switched public data network.  Terminals have access to a plurality of data channels and a control channel into the network using a balanced protocol.  The invention provides a method for reducing connect time between the terminals over the data channels.  To do this a conversation is established between a transaction program on the local terminal and a transaction program on the remote terminal.  Responsive to generation of a frame for transmission by the transaction program on the local terminal to the transaction program on the remote terminal, a channel connection between the local terminal and a remote terminal including a data channel connecting each terminal into the wide area network is established if no channel connection already exists. Responsive to expiration of a predetermined period after last transmission or receipt of a frame and existence of the channel connection for a minimum connect period, the channel connection is disestablished without interrupting the conversation between the transaction programs.  The predetermined period and the minimum connect period are optimized to minimize costs under a tariff structure for the circuit-switched public data network.

Patent CA-2148390-C (CA)
Inventor: ALBRECHT THOMAS ROBERT
IPC: G11B5/584
Filed: 1995-05-02
Granted: 2004-04-27
Abstract: Il est décrit un système d'asservissement à suivi de plage destiné à des systèmes à bande magnétique dans lesquels des motifs de piste d'asservissement magnétique contiennent des transitions enregistrées en plus d'une orientation azimutale sur la largeur de la piste d'asservissement. Le chronométrage d'un signal dérivé de la lecture en un point quelconque sur la largeur d'un tel motif varie en continu tandis que la tête de lecture se déplace sur la piste d'asservissement. Le motif est lu par une tête de lecture d'asservissement dont la largeur est inférieure au motif de piste d'asservissement. La combinaison d'un motif d'asservissement large et d'une tête de lecture d'asservissement étroite offre une excellente linéarité de la détection de position et une excellente dynamique. Dans le mode de réalisation préféré, la tête de lecture d'asservissement est également étroite par rapport aux plages de données, ce qui offre l'avantage supplémentaire d'une immunité supérieure aux erreurs de détection de position causées par des défauts ou des variations temporelles de la tête de lecture d'asservissement, des défauts du motif d'asservissement présent sur la bande, l'usure de la tête ou bande, ou une accumulation de débris sur la tête ou bande. La détection de position, au moyen de ce système, s'obtient en dérivant un rapport entre deux intervalles de motif d'asservissement et est par conséquent indépendante de la vitesse de la bande au cours de la lecture. Les motifs d'asservissement peuvent comprendre des intervalles d'espacement reconnaissables pour la détection d'erreurs et des opérations de correction. Des pistes d'asservissement sont enregistrées au moyen d'une tête d'écriture d'asservissement à motifs à entrefers multiples dont les entrefers magnétiques ont des géométries adaptées pour générer les motifs d'asservissement recherchés. Les entrefers à motifs de la tête d'écriture d'asservissement sont produits par galvanoplastie définie par voie photolithographique d'un permalloy sur une structure de tête annulaire en ferrite.

Le nouvel engrais tamponné contient des azotes concentrés de libération lente, du phosphate et des quantités de tamponnage de substances nutritives métalliques. L'urée d'alkylène peut être formée in situ à partir de liquide et conjointement à la formation de phosphate d'ammonium métallique, ou elle peut être mélangée pour obtenir des particules solides finement divisées d'urée d'alkylène. Les alkylèneurées préférées sont des polymères et des urées de méthylène, une diurée d'isobutylène et une diurée de crotonylidène. Les substances métalliques nutritives sont bivalentes et sont de préférence le magnésium, le manganèse, le zinc et le fer réagissant comme des oxydes, des hydroxydes ou des carbonates. L'ion ammonium est fourni dans ce procédé sous la forme d'ammoniac d'anhydre, d'hydroxyde d'ammonium et de préférence sous la forme d'une combinaison d'acide phosphorique et de phosphate d'ammonium. Le magnésium, l'ammonium et le phosphore réagissent selon un rapport molaire d'environ 1,0 à 1,0 à 1,0, approximativement au point d'ébulition de l'eau et environ à pression atmosphérique pour former la nouvelle composition d'engrais.
