Title: Method and device for continuous generation of cold and heat by means of the magneto-calorific effect
Inventor: SARI OSMANN
IPC: F25B21/00
Filed: 2003-12-22
Abstract: The device (10) for continuous generation of cold and heat by means of the magneto-calorific effect, comprises a chamber (11), divided into two adjacent compartments (12, 13), separated by a wall (14). The chamber (11) contains a rotating element (15) made from at least one magneto-calorific material, a first circuit (17a) with a first heat exchange fluid circulating therein and a second circuit (17b) with a second heat exchange fluid circulating therein. The chamber (11) is connected to magnetic means (16) for generating a magnetic field in the region of the compartment (12) in which the rotating element (15) is located. When the above is set in rotation the part thereof located in the first compartment (12) is magnetised on undergoing an increase in temperature. On passing into the second compartment (13), said part is demagnetised on undergoing a cooling. The heat and the cold thus generated are transmitted by means of the heat exchange fluids respectively to user circuits for heat (19) and cold (22) for recovery and use for ulterior purposes.

Abstract: L'invention concerne un procédé permettant d'effectuer un dosage immunologique. Ce procédé convient en particulier pour la détection de micro-organismes producteurs de polysaccharides (EPS) extracellulaires et/ou de lipopolysaccharides (LPS). Il est particulièrement utile pour détecter des micro-organismes qui produisent des polysaccharides extracellulaires (EPS) également dénommés polysaccharides exocellulaires, capsules, et/ou lipopolysaccharides (LPS). Dans un mode de mise en oeuvre préféré, ce procédé de détection de micro-organismes producteurs de EPS et/ou de LPS, consiste à extraire les EPS et /ou les LPS d'un échantillon avec du bromure de cétylméthylammonium (CTAB) afin de produire des agrégats moléculaires qui se lient ensuite, d'une manière préférentielle par rapport aux autres composants de l'échantillon, avec des particules de latex polystyrène colorées, à détecter les EPS et/ou les LPS ainsi liés au moyen d'un appareil de dosage immunologique à flux latéral sur lequel sont fixés des anticorps spécifiques des EPS et/ou des LPS. Ce procédé peut également servir à détecter des virus particuliers, par exemples les virus des groupes potyviridae ou tobamoviridae.

Abstract: A tube fitting for a tube end has a female threaded member that cooperates with a male threaded member. The female member includes a tube gripping device (80) in the form of a gripping ring or ferrule that is attached to the female member by a frangible web (95). Upon a partial pull-up the ferrule (80) engages a camming surface (88) on the male threaded member and breaks off or separates from the female threaded member to become a separate piece so that the fitting then functions as a single ferrule tube fitting. Additional features include a steep camming angle on the camming surface to cause the ferrule (80) to grip the tube end with a bite-type action and to form a primary seal between the camming surface (88) and a front end of the separated ferrule. The ferrule front end, and optionally the entire female threaded member including the initially integral tube gripping device, are hardened to have a hardness ratio that is at least about 3.3 times the hardness of the material of the tube end on the Vickers scale.

Abstract: A pressure relief valve is disclosed that may be used as both an over pressure control valve, preventing possible barotraumas to the patient; or as an overpressure control valve for a breathing circuit preventing over pressures caused by blockages in a breathing circuit (supplying breathing gases to a patient) with the potential to damage either the humidifier or the breathing circuit. The pressure relief valve comprises a magnetic seating that is associated with an outlet vent formed on a breathing assistance apparatus, and a magnetic cover capable of covering the seating and the outlet vent. The cover is held against the seating by a magnetic force between the cover and the seating. The outlet vent is substantially sealed by the cover and when the pressure of the gases in the breathing assistance apparatus exceeds a predetermined pressure value that overcomes the magnetic force, the cover releases from the seating to allow gases to exit the outlet vent and reduce the gases pressure in the breathing assistance apparatus.

Title: Method and apparatus for determining absolute position of a tip of an elongate object on a plane surface with invariant features
Inventor: BUERMANN DALE H
IPC: G06K11/06
Filed: 2004-12-22
Abstract: A method and apparatus for determining a pose of an elongate object and an absolute position of its tip while the tip is in contact with a plane surface having invariant features. The surface and features are illuminated with a probe radiation and a scattered portion, e.g., the back-scattered portion, of the probe radiation returning from the plane surface and the feature to the elongate object at an angle 2 with respect to an axis of the object is detected. The pose is derived from a response of the scattered portion to the surface and the features and the absolute position of the tip on the surface is obtained from the pose and knowledge about the feature. The probe radiation can be directed from the object to the surface at an angle Q to the axis of the object in the form of a scan beam. The scan beam can be made to follow a scan pattern with the aid of a scanning arrangement with one or more arms and one or more uniaxial or biaxial scanners. Angle t can also be varied, e.g., with the aid of a separate or the same scanning arrangement as used to direct probe radiation to the surface. The object can be a pointer, a robotic arm, a cane or a jotting implement such as a pen, and the features can be edges, micro-structure or macro-structure belonging to, deposited on or attached to the surface which the tip of the object is contacting.
