Patent CA-2236294-A1 (CA)
Inventor: VAN NIEL MONIQUE BODIL
IPC: C07D521/00
Filed: 1996-11-13
Abstract: L'invention concerne une classe de dérivés N-substitués de la pipérazine, de la pipéridine et de la tétrahydropyridine, liés par une chaîne alkylène fluoro-substituée à un groupe hétoroaromatique à deux cycles fusionnés tels que le groupe indolyle et portant en outre en position 4 un substituant (lui-même éventuellement substitué) du type alcényle, alcynyle, aryl-alkyle ou hétéroaryl-alkyle. Ces dérivés sont des agonistes sélectifs pour les récepteurs du type 5-HT¿1?, en particulier ce sont des agonistes puissants pour les récepteurs humains du sous-type 5-HT¿1D.alpha.?, leur affinité sélective pour les récepteurs du sous-type 5-HT¿1D.alpha.? étant au moins 10 fois plus élevée que pour les récepteurs du sous-type 5-HT¿1D.beta.?. Ils sont donc utiles pour le traitement et/ou la prévention de différents états cliniques, en particulier de la migraine et de ses effets associés, pour lesquels on recommande l'utilisation d'agonistes sélectifs pour les récepteurs 5-HT¿1D?, ces derniers provoquant moins d'effets secondaires indésirables, en particulier d'effets cardio-vasculaires, que les agonistes non sélectifs pour les récepteurs du sous-type 5-HT¿1D?.

Title: Power circuit for transferring energy by alternately switching winding circuits of a transformer at high speed
Inventor: HISANAGA KOJI
IPC: H02M3/335
Filed: 1998-05-28
Abstract: In a power supply unit, AC energy is converted to DC energy and stored into a first capacitor to which a first winding of a transformer is connected. An anti-parallel circuit of a first transistor and a diode is connected between the first capacitor and the first winding. An anti-parallel circuit of a second transistor and a diode is connected between a second winding of the transformer and a second, battery-charging capacitor. A current is induced in a third winding of the transformer for charging a third capacitor when a current is produced in the first winding in a particular direction or when energy stored in the second winding is released into the third winding. The first and second transistors are alternately switched on so that energy is transferred from the first capacitor to the second and third capacitors when the AC energy is normal and energy is transferred from the battery to the third capacitor when the AC energy fails.

Abstract: A method is provided for reducing the consumption of alkaline pH modifier in a mineral separation circuit which employs  sulfoxy  radical-containing  reagents.    The  method comprises the addition of a non-oxidizing gas to the mineral separation circuit prior to and/or simultaneously with the addition of the sulfoxy radical-containing reagent.  The non-oxidizing gas is added in a quantity sufficient to achieve a chemical environment conducive to the flotation separation of minerals.  The inventive process is suitable for a wide range of valuable minerals including sulfidic copper minerals or mixtures of sulfidic and non-sulfidic copper minerals,  sulfidic iron minerals (particularly pyrite) and non-sulfidic gangue material. It is particularly suitable for sedimentary copper deposits, copper skarns, porphyry copper/molybdenum/gold deposits and super gene enrichments.

Patent CA-2262552-A1 (CA)
Title: Methods and devices for collection of soft tissue
Inventor: BURBANK FRED H
IPC: A61B17/00
Filed: 1997-08-27
Abstract: This invention provides an inventive tissue sampling probe which offers many advantages over probes available in the prior art. Unexpectedly superior results are obtained in connection with the retrieval of intact tissue specimens, because of a unique combination of cutting features, including, for example, the employment of an electrosurgical cutting element and a vacuum assist in one preferred embodiment. A particularly important feature of the invention is the ability to manipulate the electrosurgical cutting element to cleanly sever the distal end of the tissue specimen. In certain embodiments, this is accomplished without any cutting impact on surrounding tissue. The versatility of the invention permits its use in many applications, including, for example, breast biopsies, laparoscopic surgery, and lymphadenectomy procedures.

Inventor: ANDERSSON HANS
IPC: H02H11/00
Filed: 1997-09-05
Abstract: A phase monitor for a short-circuited asynchronous three-phase motor (10) comprises a first and a second sensing unit (14, 15), both of which are connected to a supply voltage line (11) to the motor (10) in order to sense the voltage conditions on said line (11), and a control switch (18) which is controlled by the two sensing units (14, 15) and connected in a control circuit (19) for a supply voltage switch (20) for the motor (10), connected in the supply voltage line (11). When the supply voltage line (11) is connected to a supply voltage source (12), the first sensing unit (14) causes an immediate switching-on operation of the control circuit (18) if the voltage conditions on the supply voltage line (11) sensed by the first sensing unit (14) at said moment are acceptable. After a switching-on operation of the control switch (18) caused by the first sensing unit (14), the second sensing unit (15), which is operatively connected to the control switch (18) via a delay unit (21), provides a delayed control of the state of the control switch (18) in dependence upon the voltage conditions on the supply voltage line (11) sensed by the second sensing unit (15).

Title: Coincidence detection method, products and apparatus
Inventor: STEEG EVAN W
IPC: G06F17/30
Filed: 1998-03-23
Abstract: A method and system for detecting coincidences in a data set of objects, where each object has a number of attributes. Iteratively, equally-sized subsets of the data set are sampled, and coincidences (co-occurrences of a plurality of attribute values in one or more objects in the subset) are recopied. For each coincidence of interest, the expected coincidence count is determined and compared with the observed coincidence count; this comparison is used to determine a measure of correlation for the plurality of attributes for the coincidence. The resulting set of k-tuples of correlated attributes is reported, a k-tuple of correlated attributes being a plurality of attributes for which the measure of correlation is above a predetermined threshold. The method and system (implemented on an array of processing nodes) is suitable for protein structure analysis, e.g. in HIV research.

Abstract: Provided is a method of stimulating a class I-restricted immune response to a protein of interest or antigenic portion thereof in a host, as well as a protein delivery vehicle for use in the method. A nucleic acid molecule encoding the protein of interest or antigenic portion thereof is introduced into an avirulent Salmonella spp., such that the resulting Salmonella encodes a chimeric protein comprising the protein of interest or antigenic portion thereof and an injectable protein which is a target of a type III secretion system or an injectable portion thereof. This resulting Salmonella can be introduced into a host, in which the Salmonella will inject the chimeric protein into the cytosol of the cells of the host. The injection of the chimeric protein results in the stimulation of a class I-restricted immune response to the protein of interest or antigenic portion thereof in the host.
