Abstract: An arbiter which allows retried requests to have high priority  in  subsequent arbitrations  by not changing priority on a granted, but aborted, access to the bus and yet prevents the aborted requestor from thrashing the bus by masking its bus request signal until the data is available.  Further, should an access to main memory be retried, all bus requests except the one from the memory system are masked to provide the memory system the highest  effective  priority  to  allow  any  flushing operations to occur.   The masking of the various bus requests allows the arbiter to control access to a PCI standard bus without requiring that specific signals be added.  The arbiter further includes modified priority LRU techniques and provides a locking requestor with an additional, highest priority position if retried.

Title: Wellhead casing hanger assembly
Inventor: LAM TONY M
IPC: E21B19/00
Filed: 1996-09-18
Granted: 2001-01-16
Abstract: Opposed pairs of sockets are formed by the bottom surface of the slip housing and the top surface of the bottom ring of a casing hanger assembly. Vertical holes are provided in the elastomer seal element which is sandwiched between the slip housing and bottom ring. Each pair of sockets and corresponding seal element hole form a socket chamber. Rigid, motion-limiting pins are positioned in the socket chambers. Each pin has side and bottom clearances with the chamber side and bottom walls. The pins are therefore initially free floating, to allow the seal element to move to accommodate oversized casing; but the pins take up the casing load as the slip housing descends and limit its downward travel, thereby preventing excessive compression of the seal element, which can lead to casing damage.
