Patent EP-0340649-A1 (EP)
Inventor: HUGHES ROWAN
IPC: C23C18/40
Filed: 1989-04-28
Abstract: Electroless metal plating solutions are formulated and con­trolled to provide high quality metal deposits by establishing the intrinsic cathodic reaction rate of the solution less than 110% of the intrinsic anodic reaction rate. Electroless copper plating solutions contaning plating rate accelerators containing delocalized pi bonds and having the concentration of the reducing agent no greater than 1,2 times the concentration of the cooper ion can deposit copper on printed wiring boards of quality sufficient to pass a thermal stress of 10 seconds contact with molten solder at 288°C without cracking the copper deposits on the surface of the printed wiring boards or in the holes. As the plating solution ages by buildup of plating reaction by-­products or by-products and contamination, the quality of the copper deposited can be maintained by increasing the copper ion concentration and pH of the solution, while reducing or maintaining substantially constant the concentration of the reducing agent.

Abstract: The wind turbine (10) incorporates a wind vane (105) which mechanically controls a valve (100) that directs the output of a turbine driven hydraulic pump (75) to yaw the turbine out of the wind upon a loss of system power or load. The turbine yaws out of the wind at an angular rate that is roughly proportional to rotor speed so that excessive teeter amplitudes are not encountered. The mechanically driven pump advantageously provides power to yaw the rotor out of the wind even if all electrical power is lost.

Abstract: When operating an SZ stranding machine it is necessary to ensure that, during the stranding process, turning back of the individual wires (4) to be stranded occurs. This object is partially achieved by using a tubular store (3), although this solution is found to be inadequate, particularly when a rigid perforated guide disc is used. In order to achieve adequate turning back of the individual wires (4), the tubular store (3) together with the wires (4) looped around it is surrounded by at least one tubular element (7, 8, 9) on whose inner side the wires (4) to be stranded can roll off. As a result of the rolling off, adequate turning back of the individual wires is achieved. The invention can be used in the most varied types of SZ stranding machines. <IMAGE>

Abstract: Linear ignition tube suitable for the ignition of long propellant beds. The tube comprises an elongated tubular member having a ratio of interior diameter to wall thickness of at least 4. The ignition tube is provided with a plurality of ignition strands formed of an oxidizable ignition material at a density of at least 2 strands/0.001 in² of a cross-sectional area of the tubular member. The ignition strands provide a linear ignition rate for the tube within the range of 3000-6000 ft/sec. The tube can contain from 30-50 ignition strands formed of a self-oxidizing ignition material such as nitrocellulose fibers coated with a mixture of an oxidizing component such as a mixture of ammonium perchlorate and fuel component and a fuel component such as aluminum. An ignition transmission system comprises a plurality of ignition tubes which extend in a longitudinal conjoint relationship in which one tubular member at least overlaps partially another. The walls of the tubular members are sufficiently thin so that, upon ignition of the ignition strands within one tubular member, communication of the ignition reaction from the first tubular member is transmitted to the ignition strands of the other tubular member. The ignition system is useful in elongated propellant charges such as ordnance cartridges.

Abstract: An address conversion circuit quickly designates an address for making access to a memory from a CPU when the data specified by an n-dimensional address is to be processed. In order to make access to, for example, predetermined two-dimensional image data by specifying two-dimensional addresses from an arithmetic unit having an inherent scanning direction, the circuit includes two conversion means (1, 2) each for converting an address of a particular dimension into an inverse logic, exchange means (3) for exchanging addresses among addresses of said dimensions, and scanning direction determining means (4) for determining the scanning direction at the time of making access to said predetermined data, wherein the scanning direction can be arbitrarily determined for the two-dimensional addresses in the memory.

Abstract: Un appareil de détection d'énergie, qui fonctionne en détectant au moins la position d'un objet dans l'espace, comprend un détecteur (13; 23) comportant un organe de détection (14, 141; 25) destiné à détecter l'énergie captée le long d'une ligne de passage au moins (18; 24) s'étendant depuis au moins une source d'énergie (12; 22, 221). Une paire de dispositifs récepteurs d'énergie (14, 141) ou des dispositifs émetteurs (22, 221) présentent différentes caractéristiques polaires et sont disposés aussi adjacents que possible les uns des autres, en étant contenus soit dans les organes de détection soit dans la source. L'agencement est conçu de façon à permettre aux organes de détection de transmettre deux signaux (S, S1; SR, SQ1) vers un amplificateur quotientmétrique (20, 27), lequel produit un autre signal de sortie alpha dans lequel toutes les variables sont éliminées à l'exception de celle qui dépend de la direction ; PHI de la ligne de passage de l'énergie. On obtient ainsi une détection continuelle de la direction sans qu'il soit nécessaire de connaître d'autres paramètres tels que l'intensité de la source par rapport à la distance entre la source et le détecteur. Des applications de la présente invention dans les domaines de la détection de positions, de la détection passive de mouvements par infrarouges et par effets Doppler et de la détection d'incendies sont également décrites. La présente invention s'applique à des systèmes de sécurité, tels que des systèmes d'alarme avertisseurs d'effraction.

Un appareil de régulation de lumière à densité variable comprend plusieurs polariseurs, dont au moins deux sont au moins en partie croisés et au moins l'un des polariseurs étant variable dans le sens qu'il polarise la lumière en fonction d'un signal d'entrée prédéterminé, de manière à réguler l'intensité de lumière transmise (32) par l'intermédiaire de l'appareil proportionnellement à l'intensité de la lumière incidente (31) arrivant à l'appareil. La plage de régulation d'intensité peut varier en fonction de la relation de croisement des polariseurs et/ou en fonction de l'efficacité de la polarisation du polariseur régulable (10). Des effets de couleurs peuvent être obtenus. L'appareil peut être utilisé dans divers dispositifs, y compris des affichages, des fenêtres, des verres de vue et des lunettes pour ski.
