Title: Session cache and rule caching method for a dynamic filter
Inventor: VRSALOVIC DALIBOR F
IPC: H04L29/06
Filed: 1998-01-12
Abstract: A cache for use with a network filter that receives, stores and ejects local rule bases dynamically.  The cache stores a rule that was derived from a rule base in the filter.  The cache rule is associated in the cache with a rule base indicator indicating from which rule base the cache rule was derived, and a rule base version number indicating the version of the rule base from which the cache  rule was derived.   When the filter receives  a packet, the cache is searched for a rule applicable to a received packet. If no such rule is found, the filter rule base is found, and an applicable rule is carried out and copied to the cache along with a rule base indicator and version  number.    If  a  cache  rule  is  found,  it  is implemented if its version number matches the version number of  the rule  base  from which it was  derived. Otherwise, the cache rule is deleted. The cache provides an efficient way of accurately implementing the rules of a dynamic rule base without having to search the entire rule base for each packet.

Patent CA-2228353-A1 (CA)
Inventor: GRIFFIN VAUGHN
IPC: E21B17/06
Filed: 1998-01-30
Abstract: The present invention provides a disconnect which has the internal integrity to make it as strong as the rest of the drill string. The present invention can disconnect when desired, despite the fact that the apparatus is at that time subjected to significant tensile or compressive loads. The invention allows for disconnection by alternative methods. Accordingly, in one version of the tool, a ball can be dropped or pumped to a seat to facilitate disconnection. In another version of the tool, that may employ an internal wireline precluding the use of a ball, disconnection can be accomplished by compression of a stack of Bellville washers, in response to a tensile force, to release a collet-locking mechanism. Either design features a rotational locking component.

Title: A method for reactivating sorbent to enable the reuse thereof
Inventor: CHIU JOHN H
IPC: F23C10/10
Filed: 1996-07-29
Abstract: A method for reactivating for purposes of the reuse thereof sorbent containing unreacted CaO that is embodied in spent ash, which is generated as a consequence of the combustion in a fossil fuel-fired combustor (14) of fossil fuel in the presence of sorbent containing Ca. The sorbent containing unreacted CaO is subjected to steam having a predetermined temperature and a predetermined partial pressure operative to effect the conversion of the unreacted CaO to Ca(OH)2 whereby a fracturing of the sorbent occurs such that the Ca(OH)2 becomes exposed. Thereafter, the sorbent now containing Ca(OH)2 is reinjected into the fossil fuel-fired combustor (14) at a temperature within the fossil fuel-fired combustor (14) operative to effect the reconversion of the Ca(OH)2 to CaO.

Patent CA-2236671-A1 (CA)
Inventor: FELL BARRY M
IPC: B29C65/14
Filed: 1996-10-28
Abstract: A process for the continuous preparation of non-expanded honeycomb core from non-precorrugated web involves the progressive corrugation and consolidation of web by a corrugating/consolidating unit containing corrugating and consolidating elongate teeth which traverses a bed unit containing sets of former bars (1 and 4), forming a half cell height of honeycomb on each pass. A plurality of node-antinode demes of the topmost half cell layer being formed are consolidated while new corrugations and associated node-antinode demes are being formed. The process allows for more lengthy consolidation time, a smaller temperature differential between consolidating teeth and the nodeantinode demes being consolidated, and further allows the corrugating and consolidation temperatures to be substantially independent of each other. The process may be implemented through use of a corrugating/consolidating unit having a travelling belt containing corrugating and/or consolidating teeth which may be individually and selectively heated. The process and apparatus allow production of honeycomb even from thin thermoplastic web materials at high production rates. In a preferred embodiment, the teeth are radiant energy transmissive teeth associated with a source of radiant energy directed through the teeth toward the bottom, node-antinode contacting face.
