Abstract: A current collector supplies power to an electrical load movable along a conductor line and includes a movable holder for a contact element whose range of movement is restricted by two mechanical stops, and which is acted upon by a spring arrangement exerting a force in the direction of a first end of its range of movement to force the contact element against a power rail. A damping device is provided, which dampens movement of the holder caused by the spring arrangement in the direction of the first end of its range of movement, when the holder is situated within a predetermined first section of its range of movement, which is restricted on one side by the first end and does not include the entire range of movement. The damping device can be designed as a flow damper or a friction damper or as at least one spring element.

Abstract: The invention pertains to a conductor rail (1), particularly an enclosed conductor rail, with a housing (2) and at least one conductor band (4, 6) extending therein, as well as a connector (3) for connecting the conductor bands (4, 6) of adjacent segments (1a, 1b) of the conductor rail, wherein the electrically conductive conductor bands (4, 6) are bent outward at the ends of the conductor rail segments so as to electrically connect the conductor bands. In order to easily and manually produce a connection between conductor rail segments of such a conductor rail with the fewest components possible and such that a high system reliability is preserved, the invention proposes that the conductor bands (4, 6) be bent outward by 180° and that the connector (3) be realized in the form of a clamping connector that encompasses and presses the bent ends of the conductor bands against one another in the region of their bend forming a contact surface (5).

Abstract: The present invention is directed to a spring energized cage centering device for a bi-directional overrunning clutch. The clutch includes an inner race, an outer race, and a cage disposed between them. A biasing member is disposed between a cavity formed in the outer periphery of the inner race and a pocket formed in the inner periphery of the cage which permits rotational movement between the inner race and the cage, but rotationally biases the cage with respect to the inner race toward a neutral position. In one preferred embodiment, the cavity extends through the centerpoint of the inner race to form two openings in the inner race, the biasing member extending through the cavity and radially outwardly from the openings to engage the cage at two different circumferential locations.

Abstract: An operating system monitoring tool has two components: a hyperkernel that augments the operating system of a target multiprocessing system; and a graphical front end for implementing the user interface. The hyperkernel component is annexed to the operating system by: intercepting all interrupts and redirecting them from the operating system to the hyperkernel; and substituting a jump to the hyperkernel for each point in the operating system that returns back to the application code. Associated with the hyperkernel are buffers, located on the respective processors, that accumulate information pertaining to calls to the operating system. On demand, or when the buffers fill, the accumulated information is relayed to the graphical front end for filtering, manipulation, and display.
