Patent EP-0539362-A1 (EP)
Inventor: WAEHNER GLENN C
IPC: H04N5/12
Filed: 1990-09-24
Abstract: Circuits de déviation verticale destinés à éliminer sensiblement le décentrement lent et le sautillement vertical sur un écran de contrôle vidéo (260) qui, par exemple, affiche une série d'images produites par chacune des caméras d'une pluralité de caméras vidéo non synchronisées (161, 162), un signal de synchronisation verticale (230) à l'entrée de l'écran n'étant qu'un signal composite constitué des signaux individuels de synchronisation verticale (210, 220) générés par chacune desdites caméras. Plus spécialement, les circuits de déviation verticale (300) génèrent, à partir de ce signal composite de synchronisation, un signal approprié de balayage vertical pour l'une des caméras afin de placer correctement l'image vidéo générée par cette caméra sur ledit écran de contrôle. Etant donné que les circuits de déviation verticale sont redéclenchables (310), lorsque'une perte de synchronisation se produit entre une caméra et un écran de contrôle, ces circuits peuvent établir un état de synchronisation verticale sur la prochaine impulsion de synchronisation verticale dans le signal composite de synchronisation. Il n'est donc pas nécessaire d'attendre que plusieurs trames verticales se soient produites avant d'obtenir une synchronisation verticale entre ladite caméra et ledit écran de contrôle.

Title: A method of and an apparatus for producing an optical multi-fibre cable element.
Inventor: PAEIVINEN TEUVO
IPC: G02B6/44
Filed: 1990-11-15
Abstract: A method of producing an optical multi-fibre conductor element (11) by extruding (5) a secondary sheathing (6) loosely around a fibre bundle of several optical fibres (1); providing the fibres with a desired extra length (8) with respect to the secondary sheathing; and reeling the conductor element onto a receiving reel (12). In order to provide an extra length to compensate for differences occurring in the tension of the fibres and to avoid permanent variation in the length of the fibres in the secondary-sheathed fibre bundle, the fibres are spread (14, 15) side by side before the extrusion of the secondary sheathing, and passed side by side around an equalizer wheel (13), and further to the extruder while still positioned side by side. An apparatus for realizing the invention comprises means (14, 15) for spreading the fibres before the extruder (5); and an equalizer wheel (13) around which the fibres are arranged to be passed side by side.

Title: Coating metal on poly(aryl ether ketone) surfaces.
Inventor: SHERMAN EDWARD S
IPC: C08K3/00
Filed: 1990-10-31
Abstract: A method of coating metal on a poly(aryl ether ketone) surface comprises treating the surface with a swelling agent, removing the swelling agent, etchinig the treated surface and then plating the etched surface with a metal using an electroless plating process. The process can be used to metal plate articles of poly(aryl ether ketones) of complex shapes, such as electrical connectors. Exceptional bond strength between the metal and the poly(aryl ether ketone) surface is obtained. Poly(aryl ether ketone) compositions, even those containing little, or no, glass or mineral fillers can be plated with a strongly adherent coating of plated metal using a process of this invention. The poly(aryl ether ketone) may contain additives such as pigments, fillers, stabilizers, reinforcing agents or the like. Blends of poly(aryl ether ketones) with other polymers, such as polyetherimides, fluoroelastomers, or the like, can be treated in accordance with this invention.

Abstract: A two-stroke engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector (14) arranged on the periphery of the inner wall of the cylinder head. A depression (15) extending from the point beneath the spark plug to the point beneath the tip portion of the fuel injector is formed on the top face of the piston (2). When the engine is operating under a light load, fuel is injected by the fuel injector only once toward the depression, and conversely, when the engine is operating under an intermediate load, fuel is injected twice. Namely, a first injection is carried out when the piston is at a lower position, and a second injection is carried out when the piston is at a higher position, to thus direct fuel toward the depression.

Abstract: A control system for a vehicle safety device includes a pair of acceleration sensing circuits (10a, 10b). The outputs of the acceleration sensing circuits correspond to a deceleration of the vehicle in a direction of running of the vehicle, and are in opposite phase with each other. A differential calculation device (20a, 20b, 130a, 130b) effects calculation in accordance with the difference between the outputs of the acceleration sensing circuits, so as to cause noises, applied to the acceleration sensing circuits, to cancel each other, thereby preventing an inadvertent activation of the vehicle safety device due to such noises. According to another alternative construction, in order to prevent the inadvertent activation of the vehicle safety device due to the noises, the opposite-phase outputs of the pair of acceleration sensing circuits (10a, 10b) are integrated by a pair of integrating circuits (30a, 30b), and a pair of collision judgment circuits (40a, 40b) compare the outputs of the integrating circuits with respective threshold levels so as to judge whether a collision has occurred. A drive circuit (70) activates the vehicle safety device when the pair of collision judgment circuits both judge that the collision has occurred.

Abstract: An air curtain fume cabinet, in which an air curtain jet is directed across the face opening to an exhaust duct. Sufficient flow is exhausted at the exhaust duct to swallow (i) the entire air curtain jet, plus (ii) all of the air which the jet entrains from outside the face opening, plus (iii) a substantial additional amount of air. This greatly increases the velocity of air moving into the curtain at its top, beyond the normal entrainment velocity, and prevents spill-back of jet air to the outside even with substantial crosswinds. Preferably the ratio of exhaust flow to jet flow is between 2 and 3 for a jet height to jet thickness ratio of up to about 15. Preferably auxiliary air is supplied to the working space interior to replace air entrained into the jet from inside the working space.

Abstract: Un démultiplicateur comprenant une multiplicité de bascules (31-34) varie sa division de fréquence pour corriger la phase à un rythme correspondant à 0,5 cycle d'horloge. Chaque bascule (31-34) répond en continu et de manière synchrone soit à un flanc ascendant (31, 33), soit à un flanc descendant (32, 34) des impulsions d'horloge (CK). En général, l'état du démultiplicateur voyage le long d'une des deux boucles, ce qui produit des impulsions de sortie possédant des fréquences de répétition identiques. Lorsqu'un signal de commande (X, Y) est appliqué, l'état du démultiplicateur voyage d'une boucle à l'autre, produisant au moins une sortie à une fréquence de répétition alternative. La fréquence de répétition alternative est soit inférieure, soit supérieure à la fréquence de répétition identique par un nombre entier de demi-cycles des impulsions d'horloge d'entrée (CK). Là où il y a deux signaux de commande (X, Y), une fréquence de répétition alternative supérieure ou inférieure peut être choisie. Puisque les bascules (31-34) répondent à n'importe lequel des flancs des impulsions d'horloge (CK) sans interruptions de déclenchement d'horloge, il n'y a pas d'instabilité et la robustesse du démultiplicateur est améliorée. La fréquence d'horloge peut aussi être efficacement diminuée de moitié.
