Title: Procede de preparation de 4,1',6'-trichloro-4,1',6'-tridesoxygalactosaccharose
Inventor: ZHBANKOV ROSTISLAV G
IPC: C07H5/02
Filed: 1999-01-04
Abstract: L'invention concerne le procédé de préparation de 4,1',6'-trichloro-4,1',6'-tridésoxygalactosaccharose qui peut être utilisé comme ingrédient sucré (édulcorant) de sucrosité accrue, notamment dans les industries alimentaire et pharmaceutique. L'agent édulcorant le plus couramment utilisé est un glucide naturel connu sous le nom de saccharose. L'invention se rapporte à un procédé de préparation de 4,1',6'-trichloro-4,1',6'-tridésoxygalactosaccharose, à l'aide d'un saccharose utilisé en tant que matière de base. Ledit procédé consiste à acétyler sélectivement le saccharose dans de la pyridine, à chlorer le produit monoacétylé dans un réactif de Vilsmeier, à peracyler le chlorodérivé dans de la pyridine et à estérifier et à isoler le produit souhaité. On a découvert que les conditions idéales pour la phase d'acétylation sont les suivantes : le poids de l'excédent de pyridine étant 10 fois celui du saccharose, la réaction est menée à bien à la température ambiante avant le retour au processus dans lequel la pyridine est utilisée, cette dernière étant supprimée de la zone de réaction par distillation et congélation. La condition de préparation préférée du réactif de Vilsmeier est la mise en réaction du pentachlorure de phosphore avec du diméthylformamide (DMF), à une température de 0-25 °C, en l'absence d'humidité. La chloration est de préférence conduite par addition graduelle d'une solution de monoacétate et de saccharose 6 dans DMF, dans la solution préparée de réactif de Vilsmeier, la température étant maintenue au-dessous de 20 °C, la réaction étant ensuite portée à 108-110 °C pendant au moins 1,5 h. La chloration est conduite pour le mélange de produits reçus dans la phase d'acétylation directe, sans séparation chromatographique du mélange sur une résine échangeuse d'ions. La peracylation est conduite au moyen d'anhydride acétique dans de la pyridine, de préférence à la température de 50 °C, pendant 1,5 à 2,5 heures. La désacylation est conduite au moyen de méthoxyde de sodium dans de l'alcool, à la température ambiante, pendant au moins quatre heures, avec un pH de 8,8-9,0, suivie de la neutralisation de la réaction par une résine échangeuse d'ions dans H-+. Le rendement total est de 60 % à 85 % de pureté. Le procédé de l'invention présente l'avantage de permettre la réduction des phases de synthèse et la simplification de leur mise en oeuvre, l'augmentation considérable du produit (final) souhaité, la maîtrise rapide et fiable de toutes les phase du processus technologique au moyen de méthodes d'analyse spectrale.

Title: Turret type labeling machine
Inventor: MITCHELL MONTE C
IPC: B65C3/12
Filed: 1989-10-27
Abstract: ABSTRACT OF DISCLOSURE            Turret type  labeling machine  in which labels are picked  up by  a rotating vacuum drum at  a  label receiving  station,  holding  the  label  on  its cylindrical surface by vacuum while transporting it to a label applying station and releasing the label to a container at a label applying station.  A turret type of container transport is provided which rotates about an axis parallel to the vacuum drum axis and which has pairs  of chucks which rotate orbitally with  the  turret,  each  pair  of  chucks, in  turn, clamping a cylindrical container between them and causing each container to come into tangent contact with a label on the vacuum drum at the label applying station.  The vacuum drum and the turret move in the same rotational direction, e.g. clockwise as viewed from above.  The chucks and containers are caused to spin about their individual axis,  in the opposite rotational  direction,  e.g.  counterclockwise  as viewed from above.  By this means each container and the label that is being applied to it move in a direction such that the label does not interfere, e.g. tangle with the next container.  Therefore the pairs of chucks and containers can be packed more closely together and/or containers of larger diameter can be efficiently labeled.

Title: Sensing system using optical fibers
Inventor: NAKAMURA KAZUNORI
IPC: G01M11/02
Filed: 1989-12-01
Abstract: There is provided a sensing system using optical fibers having loss characteristics subject to variations for a signal light wave as a pumping light wave with a wavelength different from that of a signal light wave is coupled into said optical fiber.  Unlike conventional OTDRs that utilizes a light back scattering in an optical fiber, a sensing system using optical fibers according to the invention utilizes the light passing through an optical fiber as a detected signal in order to enhance the efficiency and effectiveness of the system and therefore it has a significantly improved S/N ratio and a dynamic range of measurement as compared with those of conventional OTDRs.  Moreover, continuous light may be used for the signal light wave (detected signal) to increase the rate of light emission for detection and to reduce the time required for measurement, providing remarkable advantages of the system when used for industrial applications.

Inventor: PRICE JOHN D
IPC: H04Q11/04
Filed: 1990-04-11
Abstract: An improved Packet Assembler/Disassembler (PAD) optimizes the assembling of characters into packets for transmission over a packet network. The PAD is arranged to operably connect to and receive character asynchronous data from one or more terminal instruments operating in either a block transfer mode or an  echoplexing  mode.  Characters received by the PAD from a terminal instrument operating in an echoplexing mode are forwarded with no PAD delay. Characters received by the PAD from a terminal instrument operating in a block transfer mode are similarly forwarded with no PAD delay and in full packets withthe exception of the last few characters of each block of characters which only partially fill their respective packets.  And these partially filled packets are quickly forwarded  in   a time period which  just exceeds the  period required for the reception of a single character at the rate of data reception from the terminal instrument.
