Title: Improvements relating to the specificity of gene expression
Inventor: O'REILLY DAVID
IPC: A01H5/00
Filed: 1998-03-27
Granted: 2010-10-12
Abstract: This invention seeks to improve the specificity of gene expression by targeting a specific expression site of a target gene. There is thus provided a chimaeric gene which comprises a promoter which expresses in more than one region of the organism to be affected. The promoter is linked to an agent which affects the functioning of an endogenous gene in the plant which is also expressed in more than one region of the plant. The promoter and agent are selected so that there is an overlap in their expression sites at one or more desired locations.  This overlap site(s) gives increased specificity and targeting of gene expression.

Abstract: A fitted top sheet for a bed has pockets for receiving a mattress at a toe end of the sheet, and a transverse pleat or flap at the toe end for accommodating the user's feet. The pleat and the mattress pocket are formed form a single notch cut into each corner of the toe end of the sheet, with the opposed sides of each notch joined together with a single seam extending the length of the notch. The seam may be formed from a line of stitching of a contrasting colour from the sheet body, to form a visual indicator to readily identify the upper or lower sides of the sheet. The sheet is fabricated by a method of cutting a notch into the two lower toe corners of the sheet, with the notch having an interior, relatively steep region, merging with a peripheral relatively shallow region.

Abstract: L'invention concerne un procédé et un dispositif permettant de transmettre des données dans un système à porteuses multiples, par codage des données et division des symboles codés résultants, aux fins de transmission sur différentes fréquences. L'émetteur comporte un processeur pilote (50) qui détermine la capacité de chaque voie dans une pluralité de voies et qui sélectionne un débit pour chacune de ces voies en fonction de la capacité déterminée. Une pluralité de sous-systèmes de transmission (56 à 72) réagissent au processeur pilote (50). Chaque sous-système est associé à une voie correspondante dans la pluralité de voies, permettant l'embrouillage des données codées, par des codes spécifiques aux différentes voies, aux fins de transmission sur lesdites voies. Un démultiplexeur variable (56) régi par le processeur pilote (50) assure le démultiplexage des données codées dans la pluralité de sous-systèmes de transmission, d'après un taux de démultiplexage dérivé des débits que l'organe de commande choisit pour les voies. Selon une variante de fonctionnement des sous-systèmes de transmission, les symboles codés sont injectés dans une unité de répétition des symboles (58) qui maintient à un niveau fixe le débit de symboles des données à transmettre. Selon une autre variante, aucune répétition des symboles n'est assurée, et l'on utilise des séquences de Walsh à longueur variable pour traiter les variations de débit.

Abstract: A method and apparatus for manufacturing any given length of a completion filter assembly is described. An outer perforated jacket is assembled over the filter media, which is itself placed over a coarse support screen or drainage layer. In the preferred embodiment, the drainage layer and outer jacket have end rings such that when advanced through a die are pushed together with the filter media in between to effect a seal of the subassembly. The subassembly can then be placed on a support pipe which is perforated, and if metallic, the end rings are welded to the support pipe to complete the assembly. Optionally, many of the components can be made of materials which lend buoyancy to the assembly so that when it is advanced into a long lateral, it will float to assist in its proper positioning.

Abstract: A vacuum cleaner capable of collecting wet or dry media includes a hose having an inlet end and an outlet end that is coupled to the vacuum cleaner. A motor is supported by a portion of the vacuum cleaner and applies a vacuum to the outlet end of the vacuum hose. A media inlet is positioned near the inlet end of the vacuum hose. An air intake for admitting air into the vacuum hose is provided near the media inlet. The air intake can be adapted to receive a detachable separate device in order to provide an air intake that is remotely positioned from the media inlet. Alternatively, the air intake can be provided on an attachment to or an integral part of the vacuum hose for providing the air intake at a remote distance from the media inlet. A distal end of the vacuum hose is immersed in a liquid to be collected so that the media inlet is immersed in the liquid and so that the air intake is exposed to a source of air. A vacuum is applied to the vacuum hose to collect the liquid through the media inlet while air is simultaneously drawn via the air intake into the vacuum hose and mixed with the collected liquid to increase the liquid lift height capability of the vacuum cleaner.

Title: Composition antigel pour moteur diesel
Inventor: TURCOTTE DAVID E
IPC: C02F5/10
Filed: 1999-05-21
Granted: 2007-02-06
Abstract: La présente invention se rapporte à des formulations inhibant la corrosion, de longue durée et très résistantes, ainsi qu'à des compositions permettant d'inhiber la formation de calamine minérale et la corrosion des métaux, notamment l'érosion par cavitation de l'aluminium en présence de liquides aqueux. La combinaison d'un mélange de polycarboxylates polymères, d'azoles, d'une association de nitrites et de nitrates, de phosphates, de silicates stabilisés et de composés métalliques de transition assure un effet protecteur synergique contre l'érosion par cavitation de l'aluminium dans des liquides aqueux réduisant le taux de corrosion, et est efficace à des concentrations relativement faibles et dans des gammes de pH variables. L'addition de polycarboxylates polymères sélectionnés ne réduit pas seulement de manière importante l'érosion par cavitation des fluides de refroidissement à base de glycol, la corrosion de l'aluminium de composants évacuant de la chaleur, la formation de précipités dans les eaux dures et l'entartrage, mais on a également découvert que les polycarboxylates polymères combinés à des silicates stabilisés par du siloxane renforcent la stabilisation des silicates secondaires, ce qui permet d'accroître la protection contre la corrosion de l'aluminium et la durée de vie des fluides de refroidissement lorsque ces polycarboxylates sont ajoutés à des quantités sélectionnées des additifs ci-dessus mentionnés. Ces formulations sont particulièrement adaptées aux applications automobiles.

Abstract: The genomic structure including the sequence of the intron/exon junctions is disclosed for KVLQT1 and KCNE1 which are genes associated with long QT  syndrome. Additional sequence data for the two genes are also disclosed. Also disclosed are newly found mutations in KVLQT1 which result in long QT  syndrome. The intron/exon junction sequence data allow for the design of primer pairs to amplify and sequence across all of the exons of the two genes.  This can be used to screen persons for the presence of mutations which cause long QT syndrome. Assays can be performed to screen persons for the presence of mutations in either the DNA or proteins. The DNA and proteins may also be used in assays to screen for drugs which will be useful in treating or preventing the occurrence of long QT syndrome.
