Abstract: A device consisting of a deformable support equipped with at least four independent wheels (5, 55 and 45, 65) and comprising a horizontal transom (3) and two sole bars (4, 44) which pivot and can be inclined relative to the transom (3). 
<??>The two sole bars (4, 44), each provided with at least two wheels (5, 55 and 45, 65), are mounted on articulated elements (7, 47) fixed to the transom (3) on either side of the longitudinal axial vertical plane of the vehicle, such that the articulation pivots (for example 18, 38, 52, 91) of the sole bars (4, 44) have variable relative positions. This results in a compensation of the reduction in distance between sole bars (4, 44) which occurs when they pivot, and hence a constant good match between the spacing of the wheels (5, 45, 55, 65) and the width of the track.

Abstract: Process for the evaporative concentration of liquids. Vaporization is carried out by indirect heat exchange with a heating fluid in an evaporator. The vapor produced in the evaporator is thereafter condensed in a condenser by indirect heat exchange with a cooling liquid which is mainly composed of the liquid to be concentrated or the liquid which has already been concentrated in the evaporator. The vapor pressure over the cooling liquid in the condenser may be lowered by causing gas to flow in contact with the cooling liquid.

Abstract: Dans le dispositif décrit, les substances qui sont absorbées dans la plage de longueur d'ondes du faisceau laser sont libérées dans le champs opératoire avant ou pendant le traitement. Ces substances peuvent être libérées dans le canal d'aspiration ou de rinçage de la pièce à main chirurgicale, de manière contrôlée au moyen d'une unité de dosage. La libération de substances telles que la sulfisomidine ou la sulfacétamide accroît la vitesse d'ablation et abaisse le seuil du processus d'ablation.

Abstract: The invention relates to a method and an apparatus for investigating a filling of liquid in a container, e.g. a fuel tank in respect of actual volume, density, temperature, opacity or other condition. From an emitter (19) at the bottom of the container there are emitted pulses of ultrasonic waves which are reflected by one or more horisontal border faces (17, 21) of the liquid and returned to the bottom of the container and detected by a receiver (20) there. The passage times of the reflected signals are compared with the passage times of direct and not-reflected signals that are detected by a plurality of receivers (1, 2, 3, 4, 5) placed above each other in fixed known positions. The result of said comparison is made the basis of a calculation of the sought qualitity. Measurement of the passage times, comparison, calculation and exposition of the result takes place by the use of electronic or data equipment (23).

Abstract: The invention relates to a method for making hinges in flat cardboard material, which on one side are groove-shaped and on the other side are bead-shaped, for example for file covers, book bindings and cardboard boxes with folding tops and the like. The flat material is compressed on the groove side by a compression edge (14), which plunges into the flat material, and at the same time folded, forming the groove, and on the bead side deformed by bending at two places at the same distance on both sides of the compression edge about in each case a bending edge parallel to the compression edge, in the opposite direction to the folding, forming bead outer edges. During the plunging of the compression edge into the flat material, the mutual distance between the bending edges is reduced. In order to obtain an easy-running hinge with only low restoring forces and to avoid surface damage in the compression process, it is proposed according to the invention that the flat material parts projecting beyond the bead outer edges are clamped independently of one another at clamping points (46, 52) close to the neighbouring bending edges and, during plunging of the compression edge into the flat material, are moved towards one another in mutual alignment.
