Title: Administration d'une pression dans un traitement de ventilation spontanee en pression positive continue
Inventor: BERTHON-JONES MICHAEL
IPC: A61M16/00
Filed: 1998-11-06
Abstract: L'invention concerne un dispositif de traitement de ventilation spontanée en pression positive continue comprenant un générateur (34, 38, 40) de flux réglable permettant de produire un gaz respiratoire à une pression de traitement élevée au-dessus de la pression atmosphérique. Ce gaz est administré à un patient par un tube (32) de distribution relié à un masque (30) placé en connexion avec les voies respiratoires du patient. Un détecteur (44, 50, 56, 58) génère un signal représentatif du flux respiratoire du patient, ce signal étant envoyé à un contrôleur (54, 62, 64). Le contrôleur (54, 62, 64) permet de déterminer la survenue d'une apnée, de déterminer la durée de cette apnée et d'induire le générateur (34, 38) de flux à augmenter de la pression de traitement à raison d'une quantité qui est une fonction croissante de la durée de l'apnée et une fonction décroissante de la pression de traitement précédant immédiatement l'apnée.

Title: Process for obtaining of ordinary or enriched superphosphate
Inventor: GRANCHAROV IVAN N
IPC: C05B1/04
Filed: 1991-03-28
Abstract: The method is used for production of mineral fertilisers. Through the method, the concentrated sulphuric acid is used directly without preliminary dilution and cooling of the solution. This medium helps to attain a high rate of decomposition for the natural phosphate and maintain low content of free phosphoric acid in the product. The method runs in two stages. The first stage includes simultaneous mixing of phosphate (up to 70 per cent in weight) and concentrated sulphuric acid or a mixture of concentrated sulphuric acid and phosphoric acid and water (30 per cent of its total quantity). In the second stage, after the pulp is ready, the remaining quantity of the phosphate and the water are added. The prepared unthickening pulp is neutralised and, if necessary, is hydrolysed at 80 - 120 degrees C for 10 to 40 minutes.

Title: Process of making racemic bupivacaine's enantiomers, levobupivacaine's pharmaceutical compositions, levobupivacaine's pharmaceutical compositions formulated on its free base form or its pharmaceutical acceptable salts and use of levobupivacaine's pharmaceutical compositions formulated on its free base form
Inventor: SUDO ROBERTO TAKASHI
IPC: A61K31/4453
Filed: 2001-04-05
Abstract: The prevent invention describes a new method for the separation of bupivacaine enantiomers consisting in a continous separation process performed without heating, by the selective precipitation of their diastereomeric salts with tartaric acid. This heatless process avoids the degradation of the reagents granting a continuous process feature to the procedure. Another embodiment of the present invention is related to the enantiomeric manipulation of bupivacaine enantiomers in order to obtain pharmaceutical compositions presenting several enantiomeric excess of levobupivacaine to quantify and determinate the role of the dextrobupivacaine on its anesthetic and cardiotoxic effects. These enantiomeric manipulated compositions showed to present an expressive improvement on its anesthetic properties that has shown to be similar to racemic bupivacaine presenting a cardiotoxic profile similar to enantiomeric pure levobupivacaine.

Title: Very high speed error detection network
Inventor: AVANEAS NAPOLEAN G
IPC: H03M13/09
Filed: 1990-02-15
Abstract: ABSTRACT OF THE DISCLOSURE           A very high speed cyclic redundancy code (CRC) generator/tester used to implement a CRC polynomial for purposes of detecting errors in telecommunications data.  A given n-bit word message to be transmitted over some medium is first processed by the very high speed CRC generator/tester in order to generate, in parallel format, a cyclic redundancy code word to be attached to said message. The n-bit word message plus cyclic redundancy code word is then processed, in a manner identical to processing at transmitter, at the receiver in order to establish if a transmission error has occurred.  The parallel processing offered by this very high speed CRC generator/tester allows for much greater processing speeds than the prior art.
Patent CA-2012256-A1 (CA)
Title: High speed asynchronous data interface
Inventor: PICKERING ANDREW J
IPC: H03M5/06
Filed: 1990-03-15
Abstract: ABSTRACT:-A High Speed Asynchronous Data Interface A digital data interface for high speed asynchronous data transfer is described. The design is nominally intended for integration onto the component chips in communications systems. The system is described with respect to its realisation in CMOS IC technology. The techniques involved, however, may easily be applied to other technologies. The interface employs Manchester Bi-Phase Mark encoding of the clock and data to allow extraction of the clock and data signals at the receiver. Furthermore, use of this Manchester code allows code violations to be easily employed as frame markers for synchronisation means. The essence of the clock extraction and data detection circuit is the use of calibrated delay line elements to suppress data transitions within the coded input signal, thus allowing the clock transitions to be detected from which the clock is then generated.

IPC: C06B21/00
Filed: 1990-06-05
Abstract: A method for producing an emulsion explosive comprises introducing a liquid organic fuel phase and an immiscible liquid oxidiser phase into apparatus having a mixer chamber, flow constrictor means for introducing the liquid oxidiser phase as an emergent turbulent jet into the chamber to cause its fragmentation into droplets in situ within the chamber, means for introducing the fuel phase into the chamber so that the fuel phase introduced thereby contacts and becomes distributed around the droplets of oxidiser phase as they form to produce emulsion and further providing shear mixing means within the mixing chamber to effect enhancement of the mixing of the chamber contents and thereby to continuously incorporate the fuel phase to produce a more refined emulsion suitable for use as the basis for an explosive system, particularly emulsions of high velocity.
Patent CA-2019659-A1 (CA)
Inventor: BERGMANS JOHANNES W M
IPC: G11B20/18
Filed: 1990-06-22
Abstract: A system for transmitting a data signal at a symbol rate 1/T through a noisy dispersive channel to a data receiver is described. The channel introduces intersymbol interference and noise into the transmitted data signal. The receiver estimates the most likely sequence of transmitted data symbols by keeping track of candidate data sequences that are recursively updated on the basis of likelihood measures which are determined by estimating hypothesized channel outputs in the absence of noise. The hypothesized channel output signals in the absence of noise are estimated using one or more look-up tables. As look-up tables are ideally suited to store nonlinear input-output relations, they can account for any nonlinearity of the channel. Furthmore, because they all operate on digital data symbols, these look-up tables are often more conveniently implemented in digital technology than the linear weighing networks in receivers of the above-mentioned prior art. In this way the ability to handle nonlinear ISI is generally accompanied by a decreased receiver complexity.
