    摘要: The sheet feeder can be mounted on a typewriter or on a printer in a system for processing data. The sheets (12) which are accommodated in a feed magazine (28) are passed to the platen roller (210) by friction stripper rollers (250). After the printing operation, the sheets are passed on to a collection table (150) positioned in front of the feed magazine. The stripper rollers are permanently connected to the platen roller by way of a mechanical transmission (212, 218, 226, 245, 248) and rotate in the same direction as the platen roller. The stripper rollers (250) are mounted on an oscillating arm (252) to be selectively moved towards or away from the first sheet to be fed, by means of a first cam (254). Before a fresh sheet is fed, a second cam, (242), also coupled to the platen roller, has to be brought to a reference position by rotating the platen roller enough to expel the current sheet. The platen roller is then rotated in the reverse direction, whereby the second cam actuates a lever (262), thereby to close a clutch (260). During subsequent rotation of the platen roller in the forward direction, the clutch rotates the first cam (254) through one revolution for engaging the stripper rollers (250) with the top sheet (12), thereby effecting stripping and feed of a sheet. At the end of the rotary movement through one revolution of the cam, the stripper rollers are moved away from the sheets and the clutch is opened, making the cams inoperative independently of subsequent rotary movements of the platen roller in one direction or the other.

    摘要: One connector (14) comprises a conductive block (48) encased in insulating material (18) with a cylindrical recess (26) in the block. A wedge (38) projects into the recess. The other connector (12) has a conductive block with a cylindrical post (20) projecting therefrom for mating within the recess (26). The distal end of the post (20) has a flat (40) and an annular groove (34) defining a part annular ridge (36). When the post is inserted in the recess, relative rotation enters the wedge (38) into the groove (34), which has a helical flank on the ridge (36) such as to draw the connectors (12) and (14) together and compress their insulating materials (18) together to provide a seal.

    摘要: Un circuit intégré à l'échelle d'une microplaquette comprend quelques centaines de modules pouvant être reliés en une longue chaîne par des commandes envoyées par un terminal (XMIT) aux modules le long d'un cheminement de transmission déterminé par les signaux d'entrée d'un module en provenance des modules avoisinants et des signaux de sortie vers ces mêmes modules, dont un seulement est validé par l'un de quatre signaux de sélection. Le cheminement de transmission suit normalement une route à travers une chaîne principale de modules (M0 à M15), illustrée par une ligne continue. Des commandes peuvent toutefois être envoyées à des modules nodaux (M0, M6 et M10) pour y effectuer des sélections alternatives de direction, de manière à avoir accès aux modules (M16) etc. dans des chaînes à embranchements. Des commandes sont adressées aux modules en fonction de leur distance (F) de (XMIT). Les embranchements peuvent comprendre eux-mêmes des modules nodaux tels que (M17). Les sélections de direction normales et alternatives sont regroupées sous forme de listes dans un tableau mémorisé qui est utilisé par une unité de commande pour avoir accès à tout module désiré et rétablir ensuite la chaîne principale (M0- M15). Dans une variante, le tableau mémorisé fournit, individuellement pour chaque module, des listes de la séquence de sélections de direction nécessaires pour avoir accès au module par la route la plus courte en évitant les modules non utilisables (marqués d'une croix).

    摘要: re-inking device (11) is fitted to a cartridge (12) for an inked ribbon (29). The cartridge comprises a magazine (31) housing the ribbon (29) which is of the closed loop type and which is disposed in randomly distributed loops, and a pair of rollers (39) for the unidirectional feed movement of the ribbon (29). The re-inking device (11) comprises an ink reservoir or inker (71), an ink metering wick (72) and a spring (73). The pair of rollers (39) comprises two toothed wheels (78) and (79) and the inker (71) is disposed in a housing (76) adjacent to the wheels (78) and (79). The ink metering wick (72) comprises a bundle of capillary fibres and is disposed between the inker (71) and the wheel (79). The spring (73) presses on the metering wick (72) to hold the fibres at one end in constant contact with the outside surface of the wheel (79). The crests of the teeth of the wheels (78) and (79) are of a rounded section and the inker (71) is of a parallelepipedic shape, is of polyester fibres with external co-extrusion and contains an amount of ink such as to occupy only half the volume of the inker (71). The metering wick (72) is cylindrical and is of a longitudinal section of rhomboidal shape. The bunch of capillary filaments is formed by fibres olf elasticised nylon impregnated with phenol resin. The ends of the capillary filaments co-operate with the rounded crests of the teeth of the wheel (79) and the spring (73) acts upon the side surface of the capillary filaments to hold the ends of the filaments and the teeth of the wheel (79) in constant contact.

    摘要: The carriage (12) is displaced by a toothed belt (33) which is driven continuously by an electric motor (48) and is connected to the carriage by means of a drive element (32) engaged between two teeth of the belt and slidable on bars (27) on the carriage in a direction perpendicular to the direction of displacement of the carriage. The pulleys are provided with recesses (42, 43) capable of engaging the drive element in such a way as to move it positively in the perpendicular direction as it moves round a pulley. The carriage is also connected by means of a tension spring (58) to a strip (52) provided with indicia of an optical encoder, sensed by an optical reader (57). The upper paper pressure arrangement is formed by two rollers (85) carried by two sliders (83) fitted into corresponding longitudinal slots in the fixed support. The paper is carried by a feed reel which is carried by two arms (94) which can be fitted by catch engagement on corresponding shoulders on the fixed support. The printer is particularly suitable for being connected to the output of a personal or home computer.

    摘要: The attenuator comprises a voltage divider (50) formed by a fixed impedance (14) and a variable impedance (16), e.g. an FET, controlled by a signal on a control terminal. The control signal may be independently provided or, as shown, from the attenuator output, via a buffer amplifier (36), rectifier (62) and smoothing circuit (63). In order to reduce the effect of non-linear response of the variable impedance (16), it is connected not to a fixed reference potential butto a potential derived as a fraction of the attenuator output by way of an impedance (42) and buffer amplifier (38). This impedance (42) and an impedance (64) in the main control signal path to the terminal (24) may optionally be controlled by a signal derived from the input signal via a filter (52), rectifier (54) and smoothing circuit (56) so as to increase the bootstrapper effect on the variable impedance (16) and increase the effect of the main control signal at high input signal levels.
