Patent EP-0912166-A1 (EP)
Inventor: SANTOS CAMILLA A
IPC: B82B1/00
Filed: 1997-06-12
Abstract: Methods and compositions are provided for enhancing the bioadhesive properties of polymers used in drug delivery systems. The bioadhesive properties of a polymer are enhanced by incorporating an anhydride oligomer into the polymer to enhance the ability of the polymer to adhere to a tissue surface such as a mucosal membrane. Anhydride oligomers which enhance the bioadhesive properties of a polymer include oligomers synthesized from dicarboxylic acid monomers, preferably those found in Krebs glycolysis cycle, especially fumaric acid. The oligomers can be incorporated within a wide range of polymers including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, anhydride oligomers can be incorporated within polymers used to form or coat drug delivery systems, such as microspheres, which contain a drug or diagnostic agent. The oligomers can either be solubilized and blended with the polymer before manufacture or else used as a coating with polymers over existing systems. The polymers, for example in the form of microspheres, have improved ability to adhere to mucosal membranes, and thus can be used to deliver a drug or diagnostic agent via any of a range of mucosal membrane surfaces including those of the gastrointestinal, respiratory, excretory and reproductive tracts.

Le système comporte un ordinateur et un sous-programme recherchant les opérations de soustraction (20), de comparaison et de tri effectuées par l'ordinateur, qui comportent plusieurs nombres à deux chiffres représentant des millésimes. La soustraction (24) est effectuée pour permettre l'obtention d'une différence entre deux grandeurs. L'existence d'une différence négative (26), est vérifiée et plusieurs nombres à deux chiffres, dont la somme est 100, sont ajoutés à la différence négative (28, 29) de manière à ce que la soustraction donne un résultat exact pour des grandeurs à deux chiffres représentant les années 2000 et ultérieures. Un sous-programme similaire relatif aux opérations de comparaison et/ou de tri est ajouté au code existant de l'ordinateur.

Abstract: There is provided a simple method of producing in a
good yield a tetraalkylammonium hydroxide aqueous
solution in which the content of metal ions such as
alkali metal ions is reduced to an extremely low level. 
     High-purity trialkylamine and high-purity alkyl
chloride are reacted with each other in ultrapure water
to obtain an extremely high-purity tetraalkylammonium
chloride aqueous solution substantially free from metal
ions such as alkali metal ions, and then, the
tetraalkylammonium chloride aqueous solution is
subjected to electrolysis-dialysis in a solution state
without drying it into a solid to produce a
tetraalkylammonium hydroxide aqueous solution. Thereby,
an extremely high-purity tetraalkylammonium hydroxide
aqueous solution with little reduction in purity is
obtained in a high yield.

Abstract: On décrit des formulations agrochimiques à libération lente, destinées à empêcher le lessivage et la contamination du sol et de l'eau souterraine. Ces substances agrochimiques sont des composés organiques, lesquels présentent des structures moléculaires non polaires et non ioniques, sont adsorbés sur des argiles dont les propriétés de surface à caractère hydrophile ont été modifiées en propriétés de surface à caractère organophile, par adsorption préalable d'un cation organique possédant généralement la structure d'un ammonium quaternaire et présentant au moins un groupe benzyle attaché à l'atome d'azote de l'ammonium. Les interactions entre les molécules à la surface de l'argile résultent en une réduction de la solubilité dans l'eau de la substance agrochimique, empêchant ainsi que cette substance ne lessive le champ.

IPC: H04L12/40
Filed: 1997-09-26
Abstract: An aircraft control system improves system flexibility, scalability, redundancy, and separation. The system uses a "virtual backplane" architecture which maximizes system flexibility and scalability and allows easy integration of new functions. The architecture comprises four major elements: processing modules; input and output modules (i.e. I/O modules); database modules; and an aircraft wide system network. Inter module communication occurs via the aircraft wide system network thereby eliminating the need for point to point communication and making modules independent of physical location or what modular units (MUs) they are in. Predetermined periodic and deterministic broadcast techniques improve the safety and communications efficiency of the system.

Abstract: The present invention is generally directed to
high opacity cigarette wrapping papers. The wrapping
paper made according to the present invention contains
a mixture of a white pigment and a black pigment. The
white pigment, which can be, for instance, calcium
carbonate, has a median particle size of from about
0.1 microns to about 0.5 microns, and particularly
from about 0.2 microns to about 0.4 microns. It has
been discovered that this particular particle size
range, which is equal to one-half the wavelength of
visible light, greatly increases the opacity,
brightness and whiteness of the paper. Small amounts
of a black pigment, such as carbon, are then added to
further increase the opacity without significantly
decreasing the whiteness or brightness of the paper
relative to conventional cigarette paper.

Abstract: During the storage or transmission of information in the form of information words, a recoding occurs in channel data words, e.g. by adding interrupt bit blocks to individual data words. When decoding such a data stream, a signal direct component is determined from the channel data words which serves as a decision threshold for differentiating between zeros and ones. A prior art method uses the interrupt bit blocks added to the data words for the purpose of bringing the signal direct component to a minimal value. In contrast to this method, the invention provides that a signal direct component deviating therefrom is obtained by appropriately selecting interrupt bits for the individual data words. It has namely been shown that the optimal decision threshold deviates from the decision threshold obtained according to a minimal signal direct component due to influences with regard to production techniques and due to the probability density of the occurrence of sequences of zeros and ones of different lengths. The optimal decision threshold can be, for example, empirically determined and correlated to the minimal signal direct component in order to supplement the data words with the interrupt bit blocks in such a way that when extracting the signal direct component from the transmitted or stored data, a modified decision threshold results and thus a reduced bit error rate.

portion of the electrical terminal to prevent removal from the terminal
receiving chamber. Additionally, an insertion space (31) is formed between a
wall of the terminal housing and the plurality of terminal receiving chambers,
and a retaining member is configured to be inserted within the insertion space.
The retaining member includes at least one retaining surface arranged to
correspond with a respective resilient locking piece to prevent deflection
thereof from the normal position. At least one recess (30) is formed in the
retaining member and positioned within an outermost end of a respective
terminal receiving chamber to facilitate contact of only an outermost end of the
respective electrical terminal by an end face of a probe pin of a test unit.
When the retaining member is fully inserted within the insertion space, an
outermost end of the retaining member lies substantially coextensive with an
outermost end of the front end of the terminal housing. The retaining member
also includes a flange (11) projecting outwardly therefrom at the outermost end
to facilitate removal thereof from the insertion space, and a recess (36) is

retaining member is fully inserted within the insertion space. A notch (33) is
formed in the wall and positioned within the recess, the notch permitting ready
access to the flange for engagement of the flange by a tool to facilitate removal
of the retaining member.
