Abstract: Apparatus and method for identifying the location of a lost token signal customarily transmitted on transmission paths (15, 16) interconnecting nodes (2-7) of a network (1) to sequentially enable the nodes to write data messages onto the network. The arrival of the token signal at each node is recorded in binary counter states of a token track counter (10607) corresponding with the node. The recorded binary counter states are compared upon the failure of the token signal to arrive at a node to detect mismatches occurring between adjacent nodes binary counter states identifying the network location of the lost token signal.

Abstract: On a mis au point des procédés de détection et/ou de quantification de protéases de sérine présentant une activité catalytique, dans un liquide biologique. Les procédés sont utiles pour mesurer les enzymes actives du système de coagulation/fibrinolytique et pour évaluer le système ou des constituants du système indiquant des troubles liés à la thrombose. Les procédés consistent en l'utilisation combinée de sondes d'halométhylcétone ayant une large spécificité vis-à-vis de protéases de sérine présentant une activité catalytique, et de réactifs immunologiques spécifiques à des protéases de sérine de types particuliers. Les sondes d'halométhylcétone présentent une spécificité active sur un site; elles ne sont incorporées que dans des protéases de sérine présentant une activité catalytique. On utilise un anticorps pour obtenir une spécificité vis-à-vis du type particulier de protéase de sérine. Par la combinaison de la spécificité active sur un site des sondes d'halométhylcétone et de la spécificité de l'anticorps à un site, on détermine la fraction présentant une activité catalytique d'une protéase de sérine particulière.

Abstract: An improved bearing assembly is provided for axially retaining journal bearings (14,15) in a turbocharger (10). The turbocharger (10) includes a center housing (24) having an elongated bearing bore (28) for receiving an axially spaced pair of journal bearings (14,15) which in turn support a rotatable turbocharger shaft (12). Lubricating oil is supplied through the center housing (24) for passage to the shaft-bearing interface through radially open oil flow ports (36,37) formed in the journal bearings (14,15). A bearing spacer (42) is interposed axially between the journal bearings (14,15) such that the opposite ends of the bearing spacer (42) define a pair of thrust surfaces (52,54) for engaging and locating the axially inboard faces of the journal bearings (14,15). Additional thrust surfaces are formed on thrust members carried by the turbocharger shaft (12) to engage and locate the axially outboard faces of the journal bearings (14,15). The outer diameters of these thrust surfaces are less than the outer diameter of the journal bearings (14,15) to promote substantially unimpeded, axially bidirectional oil flow over and about the journal bearings (14,15).

Abstract: A method for detecting the presence or the dimensions or the correct position of a workpiece (16), which is clamped in the main chucking device (15) of a numerically controlled machine tool, relative to which a constructional part (19) is arranged displaceably, a desired position value (3) being predetermined for a displacement of the constructional part (19) in the direction of the workpiece (16), and the actual position value (11) of the constructional part (19) being continuously determined iteratively, is to be developed in such a way that the desired determination is possible at a lower outlay. This is achieved in that the desired position value (3) for the displaceable constructional part (19) is selected so that, in the absence of a workpiece (16,28), a stop (17,27) for the workpiece (16,28), said stop being an integral part of the displaceable constructional part (19), would be moved to a location which, in the presence of a workpiece (16,28), is within this, and in that a signal is generated when the difference between two successively determined actual position values (11) falls below a predetermined limit value and the desired position value (3) is not reached.
