Abstract: PCT No. PCT/GB90/01252 Sec. 371 Date Feb. 5, 1992 Sec. 102(e) Date Feb. 5, 1992 PCT Filed Aug. 9, 1990 PCT Pub. No. WO91/03123 PCT Pub. Date Mar. 7, 1991.Temporarily filtered video samples are formed as the sum of a previous frame output sample and a non-linear function of the difference between current and previous samples. The function is non-linear only for absolute values of differences less than 50% (preferably 10%) of the maximum range of the difference, and a smaller lookup table is used for implementing the non-linear function than would otherwise be the case.

Abstract: Appareillage pour le nettoyage de plaques électrifiées imprimées et/ou de plaques de circuits imprimés (170) après brossage de ces dernières pour retirer les décapants de brossage à la résine à l'aide de composés de terpène. L'appareillage comprend trois parties séparées, un premier logement (26) renferme l'appareillage de nettoyage au terpène (12) un second logement (136) referme un appareillage de rinçage à l'eau (16), et un système de transport intermédiaire (14) est destiné à transporter les appareils du premier logement (26) vers le second logement (136). Le système de transport intermédiaire (14) doit se trouver à un angle de sorte que l'extrémité faisant face au second logement (136) se trouve plus bas que la première extrémité. Le premier logement (26) est équipé de ventilateurs aspirants (48) pour empêcher les odeurs de terpène ou les vapeurs qui s'en échappent de sortir, et le second logement (136) est lui aussi équipé de ventilateur aspirant similaires (164) pour empêcher l'échappement de vapeur d'eau. Des épurateurs (50) sont placés dans les conduites d'éxecution (44, 46) provenant du premier logement afin d'empêcher les composés de terpène de s'échapper dans l'atmosphère. Un détecteur de flamme (90) s'oppose à l'introduction des plaques (170) ayant des flammes à leur surface on qui sont surchauffées. Une série de commandes de la température (96) empêche la température des vapeurs de terpène d'augmenter au-delà d'une valeur prédeterminée afin d'éviter l'inflammation des vapeurs.

Abstract: L'appareil de tamisage décrit (10) comprend une paire de tamis concentriques fixes (26 et 32) ayant plusieurs structures à lames (42) en rotation entre les tamis et disposées adjacentes à eux, les lames (44 et 46) de chaque structure à lames étant alignées radialement entre elles. L'appareil de tamisage comporte un conduit d'amenée de boue disposé tangentiellement (20) et un conduit d'émission de rejets lourds disposé diamètralement tangentiellement (22) à l'extrémité d'une trappe à rejets lourds. La boue composé des rejets légers et des produits acceptés s'écoule dans la zone de tamisage et, après séparation, est déchargée à une extrémité de l'appareil de tamisage par des conduits d'émission des rejets légers (58, 60 ou 60') et des produits acceptés (16) respectifs. Le conduit d'émission des produits acceptés est disposé axiellement par rapport aux cylindres des tamis et aux lames rotatives, de sorte que les chocs de pression sont pratiquement supprimés dans le processus de tamisage. L'appareil peut être conçu avec une rotation verticale ou une rotation horizontale des lames.

Abstract: A method and apparatus for analysis of picture frames containing images of rapidly moving objects; such as projectiles or vibrators, for determining position, velocity and acceleration parameters of the object. Individual picture frames taken by a high speed camera of the object against a background are logically processed to generate an image of only the background. This background image is inverted and used to remove the background from an original picture image, thereby yielding only an image of the object. The object image can be compared to a mask for identifying its location. The mask can be scanned using a course/fine process, as well as using known or derived position, velocity and acceleration information, to accurately identify position location of the object in each frame. A unique camera structure permits the generation of accurate object images using optical fiber illuminators positioned to provide back-lighting of the moving object.

Abstract: A flexible manufacturing system (1) has a stack yard (30), machine tool (10) and a stacker crane (40). In the stack yard, a pallet group (80) formed by stacking a number of pallets is stored. The pallet group (80) is transferred to a machine tool cell (10) by the stacker crane (40). Each pallet has a memory, and data of the pallet itself and the member loaded on the pallet are memorized to it. There are various kinds of members such as work-piece, tool and chuck jaw. These members are stored to the exclusive pallets made for each kind of the member. Of the members, tool and chuck jaw has its own memory and memorizes its own data. The data of all the memory could be read and written, therefore the position of the pallet, tool and chuck jaw could be controlled all the time.

Abstract: DADMAC containing polymers, both homopolymers and copolymers are used in effective coagulating amounts to treat cellulosic fibres recycled from coated broke recovery. The DADMAC containing polymers are either homopolymers or are preferably copolymers containing acrylamide. Recycle of coated broke can cause difficulties when the fibres are recycled to the paper manufacturing process because the coatings contain binders which cause what is referred to as "white pitch", the accumulation of which can cause holes in the paper, build-up of residues and sticky masses, and clogging of felts and the like in the manufacture of paper. The use of the DADMAC polymers eliminates this difficulty in making paper from recycled cellulose fibres obtained from coated broke recycle.

Abstract: On décrit un procédé et un appareil pour le traitement thermique rapide de produits, et spécialement de produits perméables au gaz et contenant de l'eau tels que la pâte à pain. La cuisson de la pâte comprend l'introduction de celle-ci dans un four ou une zone fermée (1) et son exposition au chauffage diélectrique (par exemple, ondes radio ou micro-ondes) grâce à l'utilisation de générateurs appropriés (6, 7, 7a, 8a). Pour former la croûte, on fournit simultanément de la chaleur radiante à l'aide d'une source appropriée (9) et des gaz chauds du four. Durant au moins une partie du cycle de cuisson, on augmente séléctivement la pression des gaz dans la zone (1) par addition de vapeur (10) en fonction de l'élévation de pression des gaz dans la pâte résultant de la vaporisation de l'eau à l'intérieur de celle-ci. De cette façon, on minimise la différence de pression entre l'intérieur de la pâte et l'environnement ambiant, et l'on peut faire cuire la pâte rapidement sans avoir à craindre une rupture importante. On effectue le refroidissement par réduction progressive de la pression dans la zone, en utilisant une pompe à vide (12). Si on le désire, on peut procéder au refroidissement sous vide tout en assurant la formation continue de la croûte par chauffage radiant. Le procédé selon l'invention permet d'obtenir un pain complètement cuit et refroidi en l'espace de quelques minutes.
