Abstract: A safety trocar (10) is provided in which the cutting tip (12) is withdrawn into the cannula (14) in response to counterforce being removed from the cutting tip, e.g., by the tip entering a body cavity. The cutting tip is maintained in the exposed positioned by a mechanism associated with the obturator shaft, and is automatically withdrawn into the cannula under the force of a spring (64) when the first mechanism is released by a second mechanism associated with the obturator. Penetration force is maintained at a minimum and safe and efficacious trocar entry is facilitated.

Abstract: A screening method is provided for indiscriminate detection of microorganisms associated with various periodontal diseases, such as any of the microorganisms  Actinobacillus actinomycetemcomitans ,  Bacteroides gingivalis  and  Bacteroides intermedius . In this screening method, a specimen suspected of containing antigens from one or more of these microorganisms is contacted with a microporous membrane on which immunological complexes are formed with the appropriate antibodies. In order for screening to occur, antibodies to at least one antigen from each microorganism is used. Any complexes formed on the membrane can be detected using appropriate labels and detection means to indicate the presence of at least one of the microorganisms. This method does not discriminate among the microorganisms. Also provided is a water-insoluble article and kit useful in practicing the screening method.

Abstract: A splitting tool comprises a splitting head (14) mounted on a handle (12). The splitting head comprises at least two relatively rotatable wedges (16, 18), at least one of which is also freely rotatable with respect to the handle. Each wedge has a front edge (34) for striking and penetrating an object to be split. The freely rotatable wedge has a lobe rearwardly of the front edge and a centre of mass located in the lobe, the centre of mass being offset from the axis of rotation of the freely rotatable wedge. The offset centre of mass creates a force moment about the axis of rotation. The force moment has a first rotational sense tending to align the front edges of each wedge along a common plane when the splitting head is impelled towards the object and a second and opposite rotational sense tending to separate the front edges of each wedge when the splitting head strikes the object, thereby applying splitting forces to the object in directions generally perpendicular to the common plane.

Abstract: Un système de traitement de programme d'interruption capable d'opérer de manière asynchrone avec des ressources d'unité centrale de base doit être utilisé avec un programme de gestion d'interruptions. Les programmes de gestion d'interruptions utilisés dans ledit système sont faciles à préparer. Selon ce système, un programme, interrompu par une interruption dépendant des ressources, est repris après que l'interruption soit complétée. Ce système comprend des moyens de mise en file d'attente pour évaluer si l'instruction mémorisée dans un tampon d'instructions nécessite un traitement synchrone ou asynchrone, et met l'instruction en file d'attente si elle nécessite un traitement asynchrone. Lorsqu'une interruption a lieu dans une section de traitement synchrone ou asynchrone ou en dehors de l'unité centrale, des traitements asynchrones mis en attente peuvent demeurer incomplets ou peuvent causer des anomalies. Par conséquent, le système comprend en outre des moyens d'informer le programme, au moment où survient l'interruption, à propos des contenus (des travaux non traités ou des types d'anomalies) et de la méthode d'achèvement de tout le traitement qui n'a pas été complété ou qui a causé des anomalies. Ainsi, le programme d'interruption peut reprendre.

Abstract: The head (3), with its nose end (4) leading, is passed over a wedge-shaped member (5) comprising guide surfaces (6, 7) diverging in the direction of displacement of the head. The upper jaw (11) and the lower jaw (12) of the head are each passed along one of the guide surfaces in such a way that they are forced apart. For tearing the jaws apart it is sufficient to exert a slight force in the direction of transport. The head can be continuously conveyed into the original direction and remain oriented in the longitudinal direction of the conveyor track. The head can be stably retained in simple manner, while the jaws are passed through the wedge.

Abstract: Dans des appareils de réception de signaux de données numériques dans un système de transmission numérique, particulièrement un Réseau Numérique à Intégration de Services, on atténue les problèmes de reprise de synchronisation associés à un croisement zéro irrégulier quand des terminaux multiples transmettent à un récepteur commun, en détectant la fréquence de modification du signal de données numériques entre deux positions prédéterminées (C1, C2) et en commandant l'échantillonnage du signal de données numériques par rapport à la différence entre cette fréquence de modification et une référence. La fréquence de modification correspond, dans la pratique, au ''coin'' arrière d'une impulsion d'encadrement (F), c'est-à-dire le point auquel le signal commence la transition d'une polarité à l'autre. Le ''coin'' est beaucoup plus stable, c'est-à-dire moins susceptible d'être soumis à une variation due aux effets de terminaux multiples que le croisement zéro qui le suit, étant donné que le croisement zéro peut varier par rapport au ''coin''. On peut déterminer la transition par échantillonnage du signal de données numériques sur deux positions discrètes et par définition du moment où les deux échantillons produits diffèrent en amplitude d'une valeur prédéterminée. On peut alors utiliser l'une des deux impulsions (C1, C2), notamment celle présentant une amplitude supérieure (1), à des fins de reprise de données.

Abstract: For evaluating mechanical properties of ceramics such as silicon nitride in a nondestructive state, a specific heat of ceramics being an object of evaluation is measured at a temperature not higher than room temperature. A comparison is made between a measured value of the specific heat and a known value of a specific heat of ceramics being a reference at the same temperature not higher than room temperature. By this comparison, mechanical properties of the evaluation object ceramics are presumed from known mechanical properties of the reference ceramics. A creep strength is given as one of the mechanical properties to be evaluated. It is possible to evaluate ceramics by a nondestructive inspection introduced into a production line or the like and guarantee mechanical properties with respect to individual ceramics to be supplied as products or the like in practice.

Abstract: A process for the production of 3-hydroxyalkanals, more particularly 3-hydroxypropionaldehyde, by hydration of the basic 2-alkenals, more particularly acrolein, in the presence of a solid catalyst containing acid functional groups. The catalysts are based on an inorganic support containing basic activity centers (which are at least partly occupied by a polybasic acid, of which the first pKs value is between 0 and 3, in a form in which it cannot be removed by water) enables the hydration to be carried out with high selectivity. At the same time, the disadvantages of known organic fixed-bed catalysts are avoided. Preferred catalyst are based on pyrogenic titanium dioxide with phosphoric acid fixed thereon.

Abstract: A three-dimensional test signal for a video codec(14) is generated by injecting a conventional foreground test signal at a predetermined location as a foreground component within a background test signal as a background component, the background component having a variable complexity. The three-dimensional test signal is input to the video codec and the output of the video codec is measured using conventional measurement instruments(16). The background component may be a pseudo-random noise signal, a zone plate signal or other variable complexity-type signal, with the foreground component occurring at greater intervals than the neighboring pixels used by the codec compression algorithm. The conventional measurement instruments display only the foreground component with distortions in the video codec caused by the complexity of the background component appearing in the display. A spectral display of the output of the video codec using a zone plate signal as the background component may also be used to characterize the video codec performance.
