Inventor: DROULON GEORGES
IPC: B60N2/08
Filed: 1988-11-10
Abstract: The lower profile element is substantially of a U-shaped section and includes wings having each a median zone with a semi-cylindrical channel prolongated by a bent-over portion provided for covering V-bent vertical ends of side branches of the upper profile element. A wing of the lower profile element is cut out in order to form a row of teeth having each a trapezoidal shape prolongated by a rectangular shape in order to cooperate with an L-section latch-comb formed with rectangular openings and freely mounted on a pin which is displacable by a control of the slide. A spring applies to the latch-comb a pressure permitting a passage of teeth of the latch-comb through openings formed in the upper profile element so as to cause a penetration of the latch-comb into the openings between the row of teeth of the lower profile element for latching the upper profile element on the lower profile element.

Title: Machines a deux cylindres telles que par exemple des presses a cylindres
Inventor: STRASSER SIEGFRIED
IPC: B30B15/30
Filed: 1988-12-06
Abstract: Lors de la compression et/ou du broyage de matériaux granuleux dans une machine à deux cylindres comme par exemple une presse à cylindres, les matériaux alimentés dans l'emprise des cylindres ne sont pas saisis et introduits dans l'emprise des cylindres dans la même mesure dans les zones marginales des cylindres que dans la zone centrale de l'emprise des cylindres. Ceci non seulement influence défavorablement le débit de la machine mais de plus entraîne la production de matériaux insuffisamment comprimés, qu'il faut séparer du produit fini et renvoyer en circuit fermé dans le puits de chargement des matériaux de la machine à cylindres. Selon l'invention on atteint une compression et/ou un broyage de matériaux granuleux dans l'emprise de cylindres d'une machine à cylindres sans matériaux défectueux par le fait qu'à l'intérieur du puits 12 de chargement des matériaux on dispose une glissière 13 réglable en hauteur faisant saillie dans celui-ci à partir du haut pour adapter la hauteur du talus 14, 19 du remblai de matériaux à son comportement d'écoulement en particulier dans la zone marginale du puits 12 de chargement des matériaux.

Inventor: COZIC JEAN YVES
IPC: H04L12/42
Filed: 1988-12-12
Abstract: The stations (S1to SN) are interconnected in series by a ring (A), and the system of the invention includes a spare ring (AS) interconnecting the stations in series, together with two self-healing circuits (CAM, CAV) in each station coupler (CS) between the two connectors (8, 9) of the coupler and its insertion relay (RI). The couplers are interconnected by cords (10; 11) each containing the ring (A), the spare ring (AS), and two detection links (12, 13). Each self-healing circuit includes a relay (6) and a relay control circuit (7) connected to a detection link whose other end is connected to ground in another self-healing circuit. Each relay (6) has fixed contacts (a1, a2, b1, b2), a first moving contact (C1) connected to the insertion relay (RI), and a second moving contact (C2). The second moving contacts (C2) of the two self-healing circuits (CAM, CAV) in the same coupler are interconnected by a spare link (L). In each self-healing circuit, the moving contacts co-operate with the fixed contacts so that in a rest position they interconnect the insertion relay (RI) with the ring (A) and the spare link (L) with the spare ring (AS), and in a working position they connect the insertion relay (RI) to the spare link (L).

Title: Appareil et procede de dressage automatique optimise d'une meule de rectification
Inventor: RAO SUREN B
IPC: B24B53/00
Filed: 1989-01-16
Abstract: Appareil et procédé de dressage automatique optimisé d'une meule de rectification. Une molette 14 est guidée le long d'une trajectoire 16 correspondant au profil prédéterminé à donner à la meule 10, au cours de cycles successifs identiques. On fait pénétrer la meule perpendiculairement dans la zone de cette trajectoire entre chaque cycle. La molette 14 vient ainsi en contact avec la périphérie de la meule 10 pendant un temps de contact qui augmente à chaque cycle jusqu'à obtention du profil déterminé. On décèle la durée du contact dans chaque cycle. Quand la différence entre cette durée dans un cycle donné et la durée du contact dans le cycle précédent est minimale, le dressage est terminé. Application notamment au dressage complètement automatique de meules pour rectification de pièces de précision, notamment d'engrenages.

Date Jan. 10, 1991.A method of segmenting the field of motion of an image, particularly a video image, including forming a blockwise field of motion from motion vectors allocated to image pixels, processing the blockwise field of vectors in order to extract from this field a set of dominant vectors of motion, by elimination of the vectors close to the dominant vectors, so as to retain only representatives of widened classes of motion. Then a vector of the reduced set of dominant vectors is reassigned to each block, and the resulting field, after time filtering, is used for the encoding of the image by "quad-tree" encoding. This disclosed method applies in particular, to the setting-up of the coding-auxiliary digital data to the limit of 1 Mbt/s.
