Filed: 2001-10-09
Granted: 2010-03-09
Abstract: A process for preparing an intermediate compound of formula (II): where X is as defined in the specification, R1 is haloalkyl, alkyl, alkenyl, cycloalkyl , carboxyalkyl, alkoxycarbonylalkyl, aryl or arylalkyl; R2, R3, R4 and R5 are organic groups as defined in the specification, which process comprises aromatisation of a compound of formula (III): where R1, R2, R3, n X and R5 a re as defined in relation to formula (II) and R4 is a group R4 or a precursor group thereof, and thereafter if necessary or desired, carrying out one or more of the following steps: (i) removing any hydroxy protecting groups R; (ii) converting a precursor group R4' to a group R4, or where R4' is a group R4, converting it to a different such group. Compounds obtained are useful intermediates for example in the preparation of fulvestrant. Novel intermediates are also claimed.

Title: Actionneur de toile
Inventor: NIJS FREDERIK G
IPC: E06B9/42
Filed: 2003-04-24
Granted: 2006-10-24
Abstract: Un actionneur pour toile de fenêtre ou similaire sert à tourner un enrouleur de toile jusqu'à une nouvelle position souhaitée, suite à l'application d'un couple par une source à commande manuelle, comme une roue commandée par chaîne. Le dispositif comprend un ressort hélicoïdal, logé dans une bague fixe, dont la surface extérieure est en contact avec une surface cylindrique intérieure de la bague. Lors de l'application d'un couple par la source à commande manuelle, une extrémité de chevauchement du ressort est éloignée de son autre extrémité, afin de réduire le diamètre de ressort et donc relâcher tout engagement de frottement du ressort avec la bague, ce qui permet au couple de faire tourner le ressort, laquelle rotation est transmise à l'enrouleur. Toutefois, en l'absence d'un couple appliqué par commande manuelle, le ressort et l'enrouleur restent verrouillés en position. Tout couple appliqué depuis l'enrouleur, en raison du poids d'une toile partiellement abaissée, a tendance à augmenter le diamètre de ressort et donc à assurer un engagement de frottement entre la bague et le ressort.

Abstract: A compressor assembly having a housing in which a compressor mechanism and discharge chamber are located. A first port communicates compressed gas and oil from the compressor mechanism to the discharge chamber. A one-way valve allows the compressed gas and oil to enter the discharge chamber through the first port. A second port in the discharge chamber defines an outlet in the housing through which compressed gas and oil are discharged from the compressor assembly. The second port is disposed vertically below the first port in the lower half of the discharge chamber to thereby limit the quantity of oil which may collect in the discharge chamber. The second port may be defined by a discharge tube which passes through the housing at a flat portion of the housing which thereby facilitates the welding of the tube to the housing.

Title: Method and apparatus for providing for high egr gaseous-fuelled direct injection internal combustion engine
Inventor: MUNSHI SANDEEP
IPC: F02B23/06
Filed: 2003-09-30
Granted: 2006-09-19
Abstract: A method and apparatus is disclosed for adjusting pilot fuel injection timing in relation to a main fuel injection timing into a piston cylinder of an operating gaseous-fuelled direct injection internal combustion engine using high levels of EGR. A set of engine parameters are monitored which determine engine load and engine speed and an indicator of EGR concentration within the intake charge. Pilot fuel timing relative to main fuel injection timing is then adjusted according to the engine parameters. High levels of EGR are shown to be tolerated with relatively limited penalties in regards to other emissions typically found with high EGR by reducing the relative injection timing the pilot fuel as compared to main fuel injection timing.

Filed: 2004-04-08
Granted: 2012-11-27
Abstract: A mass spectrometer is disclosed wherein the experimentally determined mass to charge ratios of ions are reported together with an error band for each mass to charge ratio determination. The error band may, for example, reflect a 95% probability or confidence that the real, true, actual or accepted mass to charge ratio of the ion lies within the error band. By accurately determining the error band the possible candidate ions in a database can be accurately restricted whilst, also guarding against over restriction.
