Abstract:
The invention provides a transducer for converting between mechanical and electrical energies. The transducer comprises an EAP laminate with a layer (2) of an elastomer material arranged between two electrode layers, each electrode layer comprising a layer (5) of a plastically deformable material, e.g. metal or a thermoplastic material, and a layer (6) of an electrically conductive material. Due to the layer of plastically deformable material, the electrode layers can be shaped into various shapes which can provide anisotropic characteristics of the transducer.
Abstract:
Es wird ein Thermostatventilaufsatz (1) angegeben mit einem Gehäuse (2, 3), einer Betätigungseinrichtung (5), die gegenüber dem Gehäuse (2, 3) verlagerbar ist, einer Feder (9), die in einer Kraftrichtung auf die Betätigungseinrichtung (5) wirkt, einer Antriebseinrichtung (11), die gegen die Kraftrichtung der Feder (9) auf die Betätigungseinrichtung (5) wirkt, und einer Blockiereinrichtung, die die Betätigungseinrichtung 5 in einer vorbestimmten Position im Gehäuse (2, 3), in der die Feder (9) gespannt ist, gegen eine Bewegung in Kraftrichtung blockiert. Man möchte die Montage des derartigen Thermostatventilaufsatzes einfach gestalten. Hierzu ist vorgesehen, dass die Blockiereinrichtung ein Verriegelungselement (8) aufweist, das aus einer Blockierposition in eine Freigabeposition verdrehbar ist.
Abstract:
The invention provides a valve with an orifice (6) and a power actuated valve structure (7) for varying a flow area of the orifice. The valve structure provides two way communication so that the orifice may be changed by application of a bias voltage between two conductive layers arranged on opposite sides of a film of a dielectric elastomer material (2), and such that a pressure in the orifice may deflect the film and thereby cause a change in capacitance of the capacitor structure defined by the conductive layers and the film.
Abstract:
A plate heat exchanger (10) of the double plate type having a plurality of stacked plate elements, each comprising a first plate (1) and a second plate (9). At least the first plate (1) is provided with a surface pattern with a plurality of dimples (5) defining a first distance to a plate plane (8), and a plurality of canal parts (6) defining a second, smaller, distance to the plate plane (8). The first plate (1) and the second plate (9) are joined in such a manner that the protruding areas (5, 6) in combination form flow paths (11) being fluidly connected to rim portions (3) of the plates (1, 9). The heat exchanger (10) provides efficient leakage detection via the flow paths (11) while ensuring a good thermal contact between heat exchanging fluids through the plates (1, 9) via flat portions (7) between the protruding parts (5, 6).
Abstract:
This invention relates to objects having a corrosion resistant surface improving the overall corrosion resistance of the object relative to the core material, preferably being titanium or titanium based. The surface layer preferably contains at least 80% of a refractory metal such as tantalum, or an alloy based on one or more refractory metals, To ensure a good adhering of the surface to the base material an alloy layer is created between a core element and the surface layer having a thickness at least twice that of the surface layer, where the alloy layer itself has corrosion resistant properties.
Abstract:
A water mist head (1) for a fire fighting system, the water mist head (1) being mounted at least 15 cm from a ceiling (5) or a wall (10). The water mist head (1) comprises a nozzle part (2) comprising a plurality of nozzles (3), and a plate (6) comprising an at least substantially plane part (7). The plate (6) is arranged between the nozzle part (2) and the ceiling (5) or wall (10), preferably adjacent to the nozzle part (2). The plate (6) prevents the sprays (4) produced by the nozzles (3) from pulling air along. Thereby it is prevented that the sprays (4) 'collapse', and a more diverted spray pattern is obtained, the water mist head (1) thereby being capable of covering a larger area. Thus, the plate (6) creates an effect similar to that of a ceiling or wall arranged adjacent to or near the nozzle part (2).
Abstract:
Es wird eine Kühlanlage angegeben mit einem Kältemittelkreislauf, der mehrere Verdampferstrecken und einen eine Verteilung von Kältemittel bewirkenden Verteiler aufweist, wobei der Verteiler ein Gehäuse und für jede Verdampferstrecke ein ansteuerbares Ventil aufweist. Man möchte mit einfachen Mitteln einen vorbestimmten Betrieb der Kühlanläge erreichen können. Hierzu ist vorgesehen, dass der Verteiler eine die Ventile ansteuernde Magnetanordnung aufweist.
Abstract:
An expansion valve (1) comprising an inlet opening (2) and a distributor (4) being arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths (3). At least two outlet openings (3) are adapted to deliver fluid in an at least partially gaseous state, and each outlet opening is fluidly connected to one of the parallel flow paths. A first valve part (7) and a second valve part (5) are arranged movably relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines the opening degree of the expansion valve. Since the distributor (4) forms part of the expansion valve, it distributes the fluid medium to the parallel flow paths prior to or during expansion of the fluid medium, i.e. while the fluid medium is in a substantially liquid state. This makes it easier to control the distribution of fluid medium to the parallel flow paths in a uniform manner.
Abstract:
A bolt and base unit assembly (1 ) comprising a bolt (2) and a base unit (3). The bolt (2) comprises a bolt head (4) and a threaded portion (5b) adapted to threadedly engage a threaded portion (8b) of a recess (8) formed in the base unit (3). A first abutment portion (9, 12) formed on the bolt head (4) and a second abutment portion (10, 11 ) formed on the base unit (3) are adapted to cooperate in deforming the second abutment portion (10, 11 ) when the bolt (2) is received in the recess (8). The deformation is sufficient to prevent the bolt (2) from leaving the recess (8). Thereby it is possible to release the connection between the threaded portions (5b, 8b) without risking that the bolt (2) is lost or dropped. The base unit (3) preferably comprises a base part (6) and a flange part (7) which may be attached/detached by means of the bolt (2). The assembly (1 ) may advantageously be used in a valve. This allows maintenance to be performed on the valve without risking that the bolt (2) is lost or dropped during maintenance. Thereby it is ensured that the valve can be reassembled.
Abstract:
This invention concerns an illuminating device for a refrigeration appliance. The purpose of the invention is to provide an illuminating device that makes a better usage of the light from the light source by spreading it evenly in the refrigeration device surrounding the illuminating device and reducing blocking of the reflected light by the light source. The illuminating device comprises a fixating structure and a bottom part, a light source mounted in the fixating structure and a reflector formed on the surface of the bottom part. The invention discloses an improved reflector for the illuminating device.
