Abstract: The component at the pick-up station of a vibratory feeder is isolated from the remaining components on the feeder by backing the remaining components away from the component to be picked up in preparation for removal of the component from the feeder at the pick-up station. A shutter (60) can be positioned over the component at the pick-up station prior to lowering the vacuum spindle (80) into contact with the component (2) so as to prevent loss of the component (2) from the pick-up station of the feeder. The shutter (60) may also have a slot (64) therein to allow a spindle (80) to pass through the shutter (60) and contact a component (2) in the pick-up station prior to withdrawal of the shutter (60), thus eliminating "teepeeing" of two components (2) which can cause sufficient inaccuracies in pick-up and subsequent placement of the component (2). Additionally, the vibrator may be halted for the brief period necessary to remove the component from the pick-up station.

Abstract: Apparatus for controlling the exposure of a record medium (4) to a radiation beam (3) during relative scanning movement between the medium and the beam to recored half-tone image separations at particular screen angles. The apparatus comprises a control signal generator (6); a controller (8,9); and a store (7) for storing a previously generated half-tone dot map under the control of the controller (9), the control signal generator being responsive to an image signal representing the colour content of an image and a signal from the store to generate a binary beam control signal by scanning the map in synchronism with the beam scanning the record medium and comparing the image signal with the current map value, the binary beam control signal being generated in accordance with the result of the comparison. The store (7) is of a size sufficient to enable the half-tone dot map to define a number of adjacent half-tone dot areas, each area corresponding to a half-tone dot and the content of at least some areas being different. The control signal generator (6) is responsive to each area in the map for generating the control signal for adjacent, corresponding areas on the record medium. The controller (8) scans the half-tone dot map in the same direction and in the same increments for all screen angles and supplies corresponding map values to the control signal generator (6). Prior to scanning the record medium at a particular screen angle, the controller (9) determines the corresponding half-tone dot map.

Abstract: Seals for rotary shafts (6) are provided where a seal is required between a rotating shaft (6) and a boundary separating two fluids (A, B), and where the fluids (A, B) are under continuous or fluctuating pressures. A differential fluid pressure across the boundary can result in leakage of fluid from one side of the boundary to the other, contaminating the fluid at a lower pressure. The seal comprises a chamber (1) having opposed apertures (4, 5) to receive a shaft (6) extending through the chamber (1). Means are provided to maintain fluid (C) in the chamber (1) at a controlled pressure. The apertures (4, 5) are arranged to provide limited leakage if any, of fluid (A, B, C) through the appertures (4, 5). By providing fluid (C) in the chamber (1) at a controlled pressure, leakage into the chamber (1) of fluid (A) from one or other side of the seal is prevented from contaminating fluid (B) on the opposite side of the seal.

Abstract: Les informations de services de santé résultant des bases de données sur les besoins des malades de consultation externe et des malades hospitalisés sont traitées par ordinateur selon des variables cliniques choisies, comprenant l'âge, le sexe, les diagnostics, et de préférence aussi la comorbidité et l'utilisation de certaines procédures. Ces variables sont clasées en ordres de complexité clinique, et, principalement au moyen de l'analyse de régresion, le degré de liens systématiques entre les varibles de complexité clinique classées sont déterminés par rapport aux coûts (et de préférence aussi par rapport à l'utilisation de procédures et aux indices de qualité) des services de santé redus à une population de patients. Dans ce procédé, les données disponibles sur l'expérience de soins de santé des patients sont liées à chaque patient de sorte que les informations sur l'état de santé de chaque patient peuvent être reliées systématiquement aux variables de complexité clinique. La détermination des liens systématiques entre les services rendus et les variables de complexité clinique permet alors de faire des comparaisons de coûts (et, de préférence, aussi de l'utilisation de procédures et d'indices de qualité). Les comparaisons sont rendues raisonnablement équivalentes en adaptant la complexité clinique des patients recevant les soins en question. On peut ainsi faire une comparaison réaliste de l'efficacité des services sanitaires de diverses sources de soins.

Abstract: Une prothèse d'articulation pour un homme ou un animal comprend un premier (20) et un second (40) éléments, chacun composé d'un matériau biologiquement compatible et conçu pour être fixé à des os respectifs (13, 14) du corps dans la région d'une articulation naturelle (16) après l'excision chirurgicale de celle-ci. Les éléments (20, 40) de la prothèse (12) ne sont pas rattachés l'un à l'autre, et, lors de l'utilisation, sont retenus ensemble de manière à former l'articulation par les ligaments, tendons et muscles du corps dans la région de l'articulation naturelle (16). Le premier élément (20) comprend une tige (21) devant être reçue dans la cavité osseuse et une tête bulbeuse (22) présentant une surface d'articulation convexe et incurvée en trois dimensions (23) et qui, sur le plan sagittal, possède un rayon de courbure qui change à l'intérieur de la longueur d'arc de la surface, laquelle longueur est d'au moins 90°. Le second élément (40) comprend une tige (41) devant être reçue dans une cavité osseuse et une tête (42) présentant une surface d'articulation concave et incurvée en trois dimensions (43) dotée de dimensions lui permettant de coulisser sur la surface convexe (23) sensiblement le long de la longueur d'arc de 90°. Ceci permet un mouvement de flexion de l'articulation prothétique, le centre instantané de rotation de l'articulation se modifiant au cours du mouvement de flexion en raison des changements du rayon de courbure, de manière à varier la distance entre les os respectifs (13, 14) et à permettre le fonctionnement naturel de ligaments parallèles autour de l'articulation prothétique, ce qui renforce l'effet des muscles fléchisseurs lorsque l'articulation est étendue et l'effet des muscles extenseurs lorsque l'articulation est fléchie.
