Abstract: A device for adjusting the profile of a roll with a deformable wall (1) mounted rotatably about a central shaft (2). Blocks (3) are aligned along the axis between a bearing face (21) of the shaft (2) and the cylindrical inner face (12), and hydraulic thrust jacks (4) are arranged between the face (21) and a bearing face (32) of the blocks (3) at the opposite, for adjusting the radial position of each block (3). The axial and transverse dimensions of each block (3) are different, and its plane and rectangular bearing face (32) works together with a single hydraulic jack (41) having an oblong working cross-section covering the greater part of the face (32). The invention applies especially to rolling-mill cylinders.

Abstract: L'invention se rapporte au domaine des munitions combustibles et concerne principalement la fabrication de fonds ou de convercles pour douilles combustibles. Selon l'invention on fabrique un objet combustible par emboutissage dans une matrice (10) d'au moins une feuille (21) de papier combustible contenant de la nitrocellulose et ayant la forme d'un disque grâce à un poinçon mobile rigide (20) exerçant une force de compression sur un poinçon souple déformable (22) disposé à l'intérieur de ladite matrice (10) entre les feuilles (21) et ledit poinçon mobile (20). Le poinçon souple (22) a la forme d'un disque épais sensiblement cylindrique, est constitué par du néoprène ou une résine silicone et présente une dureté à 20°C comprise entre 55 et 65 shores. L'opération d'emboutissage s'accompagne d'une opération de thermoformage effectuée à environ 115°C. Le procédé est particulièrement bien adapté à l'obtention de fonds de douilles combustibles portant sur leurs faces latérales des ergots ou des rainures.

Abstract: An output stage with automatic level control for power line signalling, including a controlled amplifier (F₁) and a feedback circuit for sensing the output voltage (V  O +v  O ) of the output stage and for supplying a control signal (v⁴) to a control input of                              the controlled amplifier (F₁). The feedback circuit includes a comparator (K) for comparing an alternating voltage (v₁) which is responsive to the alternating voltage component (v  O ) at the output of the output stage and which is furthermore superposed on a first direct voltage (V₁) with a second direct voltage (V₂). As control signal to the controlled amplifier (F₁) there is utilised the voltage (v₄) across the capacitor (C₄), the voltage of which increases or decreases in response to the comparison result of the comparator (K). The amplitude of the alternating voltage component at the output of the output stage can thus be kept to a substantially constant value determined by the first and second direct voltages (V₁ and V₂).

Abstract: Use is made of a levelling and aligning machine and an emitter system installed on a carriage parked on the track and emitting a fan-shaped beam in the horizontal plane for the levelling operation and a fan-shaped beam in the vertical plane for the aligning operation, these beams defining an absolute measurement base. Two receivers for the levelling operation and the aligning operation are provided in order to centre themselves, at each measurement, at the line of impact of one or the other of the said beams. These two receivers are placed on a special measurement carriage (10) at a fixed distance (b) in front of the front measurement carriage (9) of the relative measurement base, making it possible to store a specific number of aligning and levelling values. A display (EC), such as a screen, a recorder or other means, is provided in order to display these values. In a curve of the track, the vertical beam (Fr) defines a chord of this curve and the adjusted position of the receiver defines the actual value of the deflection of the curve. A computer calculates the reference value of the deflection and the divergence of the two values which determines the aligning correction. <IMAGE>

Abstract: A flexible filter bag, the filter element of which is seamless and avoids prior leakage problems, is made by wrapping a flexible, preferably perforated, filtering fabric and a flexible nonfiltering transport material together onto a cylindrical mandrel to provide a tube. A thin metal ring is fitted into the tube, and the portion of the filtering fabric which extends beyond the edge of the transport material is folded inwardly around the ring to provide a cuff. A sleeve of a length about twice that of the tube is inserted into and pulled over the tube until the free ends of the sleeve are approximately coterminous with the ring-free end of the tube. The free ends of the sleeve and tube are gathered in the manner of a sausage casing and then subjected to pressure to form a seal, but the convolutions of the transport material terminate just short of the seal so as to avoid bunching at the seal.
