Abstract: The invention is directed to a widget of or in a graphical user interface for navigating amongst related objects. The widget is adapted for displaying first and second groups of objects within respective first and second visually linked display areas. The widget is further adapted, upon user selection of a relation between an object of the second group and a third group of objects, for displaying objects of the third group in the second display area and objects of the second group in the first display area. The invention also relates to a method for navigating amongst related objects, comprising a step of providing to a user a graphical user interface with such a widget. Lastly, the invention is directed to a computer program comprising code means for implementing the method and to a computer system comprising means for implementing the method.

Abstract: The method of collaborative work takes place between a first user working on a first object (1) on the basis of a visual representation of the first object displayed in an authoring environment of a first local computer; and a second user working in an authoring environment of a second local computer connected with the first computer via a computer network. The method comprising the steps of: a) selecting at the first computer one type among a plurality of types of data about the first object, each type of data comprising visual representation data about the first object; b) providing to the second computer data about the first object according to the selected type; c) displaying a visual representation of the first object in the authoring environment of the second computer.

Abstract: Electromagnetic pump with oscillating core, connected to a hydraulic device, to transfer a fluid into the hydraulic device. The pump includes a containing body, a tubular element of amagnetic material, a core of ferromagnetic material sliding coaxially to the tubular element, an electromagnetic unit arranged around the core and coaxial to the tubular element to generate an alternating magnetic field and cause the core to slide axially and alternately with respect to the tubular element. The tubular element includes, in one piece, a first part, projecting outside both the containing body and the electromagnetic unit and having an attachment configured to be selectively associated, directly or indirectly, with mating attachment elements of the hydraulic device, and a second part disposed inside both the containing body and the electromagnetic unit and having an axial cavity in which the core slides.

Abstract: Thermoelectric installation of the "heat pump" type, in which the thermoelements 1 and the exchangers 2 and 3 are stacked to form columns, these assembled to form a rack.The rows of exchangers 2 and 3 demarcate two conduits for the circulation of a hot fluid and a cold fluid. These conduits are situated outside the stacking axes of the columns, so that adjacent exchangers can turn in relation to each other. The thermoelements and the exchangers are in contact by at least one cylindrical or spherical profile surface.This assembly allows proper tightening of the columns and therefore good contact between exchanger and thermoelement without destruction of the thermoelements.

Abstract: A thermo-electric installation comprising a first network of hot tubes extending between two ends disposed in parallel relation and in which flows a hot fluid, a second network of cold tubes, extending between two ends, disposed in parallel relation and in a plane parallel to the plane of the hot tubes, and in which flows a cold fluid, thermo-elements mounted between said hot tubes and said cold tubes, at least two mechanical connection structures, called hot structures, connecting the hot tubes together, respectively towards their two ends, these two hot structures being independent of the cold tubes, at least two mechanical connection structures, called cold structures, connecting together the cold tubes, respectively towards their two ends, these two cold structures being independent of the hot tubes, and fixing devices, for firmly connecting together the hot structures and the cold structures, situated at the same end.

Abstract: A heat exchanger for a thermo-electric installation, comprising thermo-elements mounted between a hot wall and a cold wall, including, on the one hand, two base plates each forming or supporting a hot or cold wall and, on the other hand, a plurality of heat exchange surfaces extending between these two base plates. Each heat exchange surface is formed by an homogeneous one-piece bar.
