Abstract: A method is provided for forming a thick-film circuit (10) having at least one thick-film resistor element (16) upon a substrate and laser scribing the substrate (12) to remove the circuit from the remaining portion of the substrate. A thick-film circuit (10) comprising conductor lines (14) and at least one resistor element (16) is first printed upon the substrate (12). Thereafter, the resistor element (16) may be laser trimmed to increase the resistance value thereof. After laser trimming, a protective material (18) such as ethyl cellulose is coated onto the outer surface of the resistor element to protect it from hot-slag ceramic material generated during a laser scribing operation. The substrate (12) is then topside laser scribed to separate the thick-film circuit from the remaining portion of the substrate. Following laser scribing, the protective material (18) is removed by washing the resistor element with a solvent.

Abstract: A brewer unit for a hot drinks dispensing machine includes a brewing cylinder having a pressure-applying piston and into which tea leaf or ground coffee and hot water are introduced, the base of the cylinder being a filter screen. The base and cylinder walls are movable relative to each other between a position of sealing engagement and a spaced-apart position and a wiper arm is positioned externally of the cylinder adjacent to the filter. In use, the piston applies pressure to the cylinder contents while the base and cylinder are in sealing engagement, whereby brewed beverage is forced through the filter, and the cylinder and base then move apart to allow the wiper arm to traverse the filter in the space formed, to remove spent tea leaf or coffee grounds therefrom in readiness for the next brewing cycle.

Abstract: A case for optically readable disc media such as compact discs, compact disc read only memories and video laserdiscs. A slidable carrier, which holds the disc, is housed inside a flat case. A rib of the carrier is accessible outside the case so that the carrier may be moved within the case.

Abstract: L'invention concerne un dispositif de commande d'une direction assistée hydraulique pour véhicule automobile, dans lequel l'arbre de direction (1) peut rouler, dans une faible mesure, sur la crémaillère (3), pour commander la valve de direction. Pour permettre ce mouvement de roulement, l'arbre de direction (1) est monté dans un manchon (9) qui, de son côté, est monté mobile en rotation par rapport au carter (4) du mécanisme de direction, par l'intermédiaire d'un roulement à aiguilles (10).

L'axe du roulement à aiguilles est plus éloigné du centre de l'axe de l'arbre de direction que de ce point de transmission de force. Afin de maintenir le tiroir (19) de la valve en sa position neutre, il est prévu un ressort captif (24).

Abstract: Projecteur à mécanisme de transport de film en boucle tournante sur lequel on monte une unité à cames de ralentissement du déroulement du film (52) à un endroit situé avant l'ouverture du projecteur. Des broches de ralentissement (66), supportées par une paire de bras espacés verticalement (62) qui dépassent de l'unité à cames, s'engagent dans les perforations marginales supérieures et inférieures du film et se déplacent avec le film en direction de l'ouverture tout en ralentissant le déroulement du film à chaque image. L'unité à cames comprend deux cames (56, 58), l'une provoquant le mouvement de ralentissement des broches et un mouvement de retour dans le sens opposé à celui du déroulement du film, tandis que l'autre (58) fait avancer les broches et les fait entrer et sortir respectivement du chemin du film. La rétraction positive des broches leur permet d'effectuer un mouvement de retour à l'encontre du sens de déroulement du film indépendamment du mouvement du film. Par comparaison aux systèmes existant à ce jour, les forces d'accélération et par conséquent les forces de résistance s'exerçant sur la came sont diminuées et l'unité à cames peut fonctionner à des cadences d'images plus élevées et/ou à des intervalles de rotor plus petits.
