Patent CA-2072496-A1 (CA)
Inventor: DESODT GUY
IPC: G01S13/78
Filed: 1992-06-26
Abstract: 12 RADAR SECONDAIRE APTE A SEPARER TOUTES REPONSES INDEPENDANTES La présente invention concerne un radar secondaire apte à séparer toutes réponses provenant d'avions différents. Lorsque plusieurs avions envoient au radar secondaire classique des réponses simultanées dont les bits interfèrent, les traitements conventionnels ne permettent pas de séparer ces réponses, et il est alors impossible de procéder à l'identification et à la localisation des avions. L'objet de l'invention est un radar secondaire muni, dans sa chaîne de réception effectuant de manière classique une démodulation cohérente et une numérisation des signaux X(t) reçus, d'un dispositif d'analyse en composantes indépendantes. Ce dispositif effectue tout d'abord un traitement d'orthonormalisation (1) des signaux numérisés reçus, puis un traitement de rotation (5) permettant de retrouver les signaux indépendants, et d'identifier par la suite les avions émetteurs. Les deux traitements permettent également au radar secondaire d'assurer sa fonction de localisation des avions. Figure 1.

Abstract: ABSTRACT        A selective thioketalization process for the preparation of a thioketal from a dione where one, but not the other, keto group of the dione is .alpha.,.beta.-unsaturated, and where selective thioketali-zation occurs at the keto group of the dione which is not .alpha.,.beta.-unsaturated, comprising the step of contacting the dione with a thiol, in the presence of a protic acid catalyst which is a complex of a Lewis acid and a protic source, wherein the temp-erature of the reaction medium is maintained below about 25°C during the reaction.  Preferably, further, (i) the acid catalyst is employed in excess and/or (ii) the thiol is employed in excess.

IPC: G01V1/16
Filed: 1992-09-25
Abstract: ABSTRACT    In dual-sensor, bottom-cable marine seismic exploration where hydrophone/geophone pairs are deployed on the marine bottom, coupling imperfections between the geophones and the marine bottom contribute to differences between the impulse response of the geophones and the impulse response of the hydrophones.  To correct for the coupling imperfection, a filter is designed which compensates for the inherent impulse response differences as well as response differences caused by the imperfect coupling.  Preferably, the filter is designed using a calibration procedure prior to production shooting.  First, the response of a hydrophone and geophone to a seismic wave is recorded.  Then, these recorded responses are transformed into the frequency domain.  Once transformed, the response of the hydrophone is divided by the response of the geophone to produce a filtering function.  When the filtering function is applied to geophone signals during production shooting, the filter compensates the geophone signals to alleviate differences in response characteristics between the geophone signals and the hydrophone signals.

IPC: B65H19/22
Filed: 1992-11-12
Abstract: A winding machine for winding an elongated strip on a core mounted on an axle to form a roll thereon has a support frame and an axle to receive a core on which elongated strip is to be rolled.  The support frame has two tranversely spaced parallel side members having tracks supporting opposite end portions of the axle and along which the axle is movable from a winding postion to an unloading position, and a driven roller at the winding position to engage elongated strip wound on a core on the axle to rotate the core and wind further strip thereon.  The axle with strip wound on the core is moved along the tracks from the winding position to the unloading position.  At the unloading position, one end of the axle is held by one side member in a generally horizontal attitude.  The other side member has a movable portion which in a supporting position engages and supports an opposite axle end when the axle and roll are at the unloading position and which is movable relative to the remainder of the side member to a removal position to permit the core and roll to be moved endwise off the axle.

Title: Exhaust system for a turbomachine
Inventor: GRAY LEWIS
IPC: F02C7/00
Filed: 1993-06-29
Abstract: An exhaust system for an axial flow turbomachine is provided having a diffuser that directs the flow of working fluid from a turbine exit to an exhaust housing having a bottom opening, thereby turning the flow 90° from the axial to radial direction. In the exhaust housing, the flow exiting at the top of the diffuser turns 180° from the vertically upward direction to the downward direction. The strength of the vortex formed in the exhaust housing as a result of this turning is minimized by orienting the outlet of an outer exhaust flow guide portion of the diffuser so that it lies in a plane that makes an angle with a plane perpendicular to the turbine axis. As a result, the minimum axial length of the outer flow guide occurs at a location remote from the exhaust housing outlet and the maximum axial length occurs at a location proximate the opening, thereby crowding the vortex against a radially extending baffle in the exhaust housing.

Title: Technetium-99m labeling of proteins
Inventor: SUBRAMANIAN RAMASWAMY
IPC: A61K51/00
Filed: 1992-02-27
Abstract: A method for attaching technetium-99m to proteins using reducing metal reagents to achieve binding to high affinity binding sites and high specific activity. The reagents play a dual role under the given experimental conditions by reducing disulfide bonds in the proteins to sulfhydral groups suitable for binding to technetium, and reducing pertechnetate from Tc(VII) to Tc(III) or Tc(V).  Reduction of disulfide on the protein is conducted initially with an excess of reducing metal reagent, a pertechnetate reagent is added at the end of the protein reduction reaction and allowed to continue to reduce the technetium. Thereafter a chelator scavenger is added to remove poorly bound or unbound technetium.
