Patent CA-2128061-C (CA)
Title: Pipe coupling
Inventor: BLOSE THOMAS LAYTON
IPC: F16L15/04
Filed: 1994-07-14
Granted: 1998-06-16
Abstract: A pipe  coupling or connection comprises  a  female coupling component and a mating male coupling component.  Each component is matingly threaded for coupling engagement, and each is provided with an adjacent frusto-conical sealing surface.  The sealing surface is provided with a controlled surface roughness, viz. very shallow fine surface variations, preferably formed as microgrooves at a pitch small relative to the pitch of the threads.  The slope of the frusto-conical surface of the sealing area of the male component is slightly mismatched with that of the sealing area of the female component to simulate the bearing force vs. axial distance characteristic of shrunk-fit circular cylindrical sealing surfaces.  The slight mismatch enables the sealing pressure to be above a design minimum throughout the entire sealing area yet higher at each end of the sealing area. As the coupling is assembled, thread interference in the vicinity of the sealing surface lags  the occurrence of interference between the sealing surfaces.  Load threads are provided with negatively inclined load flank faces.  Load thread interference values and tolerances are selected to enable the shrunk-fit cylindrical sealing surface simulation to be met over the range of tolerances provided.  The envelope of the range of curves of interference vs. distance along the effective pin sealing surface area has a positive slope.   The effective sealing area is at least about one-third and preferably at least about one-half of the available sealing area.

Abstract: Methodology and concomitant circuitry for compacting an incoming data stream into an outgoing compacted data stream utilize a plurality of memories or lists. The incoming data stream is partitioned into a sequence of tokens. A primary memory (3262) stores each token, with the most recently appearing token occupying the top rank in the list. A secondary memory (3282) stores the location in the primary memory of each of a subset of tokens. The compacted data stream is generated as a coded representation of the token itself, the position of the token in the primary memory, or the position in secondary memory of the location of the token in primary memory. A tertiary list may also be employed to generate a coded representation of the position in the tertiary list of the secondary list. Searching of the lists is effected with a hashing function. Updating of the lists utilizes tree splaying.
