Title: Process for the continuously operated purification by distillation of the methanol solvent used in the coproduct-free synthesis of propylene oxide, with the methoxypropanols and the high boilers being separated off simultaneously
Inventor: BASSLER PETER
IPC: C07D301/12
Filed: 2003-07-22
Abstract: The invention relates to a method for the continuous purification by distillation of methanol, used as a solvent in the synthesis of propylene oxide by the reaction of a hydroperoxide with propylene and the simultaneous isolation of the methoxy propanols. Said method is characterised in that the solvent mixture that accumulates during the synthesis is separated in a dividing wall column into a low-boiler fraction containing methanol, a mediu m- boiler fraction containing the methoxy propanols as an azeotropic mixture wi th water and a high-boiler fraction containing water and propylene glycol.</SDO AB>

Title: Encapsulation de composantes sensibles par pre-emulsification
Inventor: VAN LENGERICH BERNHARD H
IPC: A23L1/30
Filed: 2003-06-17
Abstract: Selon l'invention, une émulsion stabilisée est employée pour produire des particules solides ou pastilles à libération contrôlée, de longue conservation, discrètes qui contiennent une composante encapsulée et/ou noyée telle qu'une composante facilement oxydable telle que les acides gras oméga-3. Une composante d'encapsulation huileuse qui contient un agent d'encapsulation sensible actif dissous et/ou dispersé dans une huile est ajouté et mélangé à une composante aqueuse et à une composante filmogène pour former une émulsion. Un agent antioxydant qui sert à éviter l'oxydation de l'agent d'encapsulation sensible actif et une composante de ramollissement de film ou un plastifiant destiné à la composante filmogène peut faire partie de l'émulsion. L'émulsion est stabilisée par homogénéisation. Les pastilles sont produites tout d'abord par réduction de la teneur en eau de l'émulsion stabilisée de sorte que la composante filmogène forme un film autour des gouttelettes d'huile et encapsule l'agent d'encapsulation. Dans certains modes de réalisation de l'invention, la teneur en eau de l'émulsion homogénéisée peut être réduite par séchage par pulvérisation pour produire une poudre. Dans d'autres modes de réalisation, l'homogénéisation est suivie d'une réduction de la teneur en eau de l'émulsion par mélange de l'émulsion avec au moins une substance matricielle, de façon à encapsuler les gouttelettes d'huile entourées du film à l'intérieur de la substance matricielle. Après réduction de la teneur en eau de l'émulsion, un revêtement protecteur est appliqué sur les gouttelettes d'huile entourées du film, pour donner des pastilles.

Patent CA-2529600-A1 (CA)
Inventor: SUNDARAM GANESH
IPC: H04J3/16
Filed: 2004-06-22
Abstract: A method and system for flow control of GFP-encapsulated client data frames over SONET/SDH transport networks is described. Transport interfaces, in the form of port cards, have FIFO buffers for receiving the GFP frames. In acknowledgment of the received frames, a transmitting transport interface receives an acknowledgement in form of a returned frame sequence number tag along with the available capacity in bytes of the buffer of the receiving transport interface. With a continuous update of buffer capacity and tracking the number of bytes in transit to the receiving transport interface, the transmitting transport interface maximizes the utilization of the channel through the SONET/SDH transport network, even with dropped frames or dropped acknowledgment tags.
