  • Patent number: 7516209
    Abstract: A framework and method are disclosed for carrying out request completion tracing across request identification boundaries. When a request traverses an identification boundary, an event identifies the old and new request identifications and stores this linking information in a trace event record. Thereafter, a consumer of records maintains track of request completion by incorporating the linking information to switch identifications used to track completion of the request across request identification boundaries encountered by the system while responding to the received request. A request trace event record consumer architecture with enhanced tracking capabilities based upon a specified state machine provides greater power when interpreting the trace records associated with completion of requests by a server system.

  • Patent number: 5595275
    Abstract: A compact torsion spring assembly is functionally disposed between a first member and a second member. The first member is rotatable relative to the second member and has a first spring engagement notch therein. A bracket fixed relative to the second member has a second notch therein. A tension spring is formed as a continuous coil of steel wire, defining an enlarged diameter first catch plate portion at a first end and a second catch plate portion at a second end. The spring is disposed between the first member and the second member, with the first catch plate portion engaging the notch in the first member and the second catch plate portion engaging the notch in the bracket, wherein the spring rotatively biases the first member relative to the the second member.

  • Patent number: 5595274
    Abstract: A friction device includes an adjustment mechanism for adjusting the device in response to wear on a friction surface within the device. The adjustment mechanism includes a first cam ring and a second cam ring adjacent the first cam ring. In one embodiment, the first cam ring is adapted for axial, but non-rotational movement with respect to a cover of the friction device, the cover being secured to a driving member for transmitting torque. The second cam ring is adapted for rotational movement with respect to the cover and the first cam ring. The first cam ring has a plurality of annular ramped surfaces on an axial face of the first cam ring. The second cam ring has a plurality of annular ramped surfaces on an axial face opposing the axial face of the first cam ring.
