Title: Lipides cationiques et leur utilisation
Inventor: KIRPOTIN DMITRI
IPC: A61K9/127
Filed: 1997-05-14
Abstract: La présente invention concerne généralement un lipide non toxique conjugué avec un acide aminé cationique contenant un groupe guanidino. Spécifiquement, le lipide d'origine naturelle dioléoylphosphatidyléthanolamine (DOPE) est combiné avec l'acide aminé d'origine naturelle arginine. Lesdits composés sont utiles pour enrober et administrer des substances pharmaceutiques et des polynucléotides et oligonucléotides. Ils présentent une amélioration par rapport aux composés actuels parce qu'ils sont composés de composants non toxiques, et naturels dans le cas de Arg-DOPE, et entraînent donc des effets secondaires non désirés minimes. Des procédés d'utilisation desdits lipides cationiques sont également décrits.

Title: Method of transmission and device to carry out said method
Inventor: IANELLI ZBIGNIEW
IPC: H04B1/69
Filed: 1997-11-03
Abstract: Transmission method in which angle-modulated pulses with temporally opposite angle modulation are generated in the receiver during the duration of the pulse, which pulses are superimposed by means of a first superimposing element (8, 9), in each case in pairs, into a folded pulse, whereby the folded pulses transmitted to the receiver, after a modulation process, carry information impressed upon them, and these folded pulses are filtered at the receiver through two parallel-connected, complementary dispersion filters with frequency-dependent group delay characteristics, whereby the frequency-dependent group delay characteristics of the two dispersion filters are matched to the angle-modulation, in each case, of one of the two pulses forming in their superposition the folded pulse, in such a way that at the output of the dispersion filter, in each case, a combined signal appears that consists of one compressed pulse with increased amplitude and one expanded pulse with decreased amplitude, whereby the signals at the outputs of both dispersion filters at the receiver are combined by means of a second superimposing element.

Title: Non-woven inorganic fibre mat
Inventor: FITZSIMONS JOCELYN
IPC: D04H1/70
Filed: 1998-01-23
Abstract: A non-woven mat (18) of inorganic fibre is disclosed having a substance which is lower at the edges (26') of the mat than in the remainder (28) of the mat. Apparatus for making such a mat comprises: a source of a slurry of inorganic fibre in a liquid; a forming wire disposed to move past the source, through which the liquid passes to deposit the inorganic fibre on the forming wire; a mask across a part of the width of the forming wire to hinder passage of the liquid through the forming wire over the said part, the effectiveness of the mask varying in the direction of movement of the forming wire past the slurry source. A method of making the mat comprises passing a forming wire past a slurry of inorganic fibres in a liquid while masking a part of the width of the forming wire as it passes through the slurry, the masking varying along the length of the forming wire as it passes through the slurry; and urging the slurry against the forming wire and causing the liquid to pass through the forming wire, whereby a non-woven mat of inorganic fibre is formed having an uneven substance (weight/unit area) in the cross direction.

Title: Method for improving the exploitability and processability of guar endosperm and products obtained using said method
Inventor: STEIN ARMIN
IPC: A23L29/238
Filed: 1997-12-22
Abstract: The invention relates to a method for improving the exploitability and processability of guar endosperm. According to said method, guar splits are brought into contact with liquid ammonia at an initial pressure which is higher than the atmospheric pressure and at a temperature of at least 25 °C, whereby the amount of liquid ammonia is sufficient to moisten at least the surface of the guar splits and the remaining available guar split/liquid ammonia system volume is increased in an explosion-like manner by reducing the pressure by approximately 5 bars, resulting in the sheath of the guar-splits being torn open. Said ammonia-exploded guar splits can be ground more easily than native guar splits.

Title: Round baler belt support roll constructed for deflecting crop material away from roll clearance gaps in baling chamber side walls
Inventor: ANSTEY HENRY DENNIS
IPC: A01F15/07
Filed: 1999-07-12
Abstract: A large round baler bale-forming belt drive roll has cylindrical sections at its opposite ends which extend through circular holes provided in the opposite side walls of the baling chamber. The cylindrical sections are smaller in diameter than the circular holes, thus leaving clearance gaps between the cylindrical sections and the boundaries of the holes. A pair of wipers, in the form of rod or wire stock, are welded at diametrical opposite locations on the cylindrical sections and are located in the adjacent clearance gap. The wipers are angled relative to the axis of rotation of the roll so that as the roll rotates the wipers sweep through the gaps and cause any crop material engaged there to be moved inwardly from the adjacent bale chamber side wall.

Title: Immersed membrane module and process
Inventor: COTE PIERRE
IPC: B01D65/08
Filed: 1999-11-18
Abstract: An element for use in ultrafiltration or microfiltration of potable water has a large number of small diameter hollow fibre membranes attached in a slightly slackened state between two headers but in fluid communication with only one of the headers. Side plates attached to the sides of the headers define vertical flow channels containing the membranes. The headers, membranes, side panels and T connectors define membrane elements which may be placed side by side with other elements to create membrane modules which can be stacked on top of each other to form membrane cassettes of various sizes having continuous vertical flow channels through the entire cassette. To pot the fibres, a suitable number of fibres are gathered in a bundle and dipped in a pool of liquid wax which freezes seconds after the bundle of fibres are removed. The waxed fibre bundle is then inserted into a recess in a header. Potting resin is poured into the header to cover the fibre bundle to a depth greater than the distance that the wax wicked up the fibres. The wax is melted out of the header. The membrane modules or cassettes are arranged in an open tank to cover a substantial part of the cross sectional area of the tank, preferably 80% or more. In first and second processes, tank water flows upwards and downwards through the flow channels respectively.
