Title: Pipeline buoyancy control assembly and tie-down attachment member therefor
Inventor: KIRK WILLIAM D
IPC: F16L3/04
Filed: 1999-11-30
Abstract: A pipeline buoyancy control assembly includes a pair of anchor rods, a pair of tie-down attachment members, a pair of termination members, and a flexible endless strap having an endless loop configuration. The anchor rods are driven partially into the ground along opposite lateral sides of the pipeline. The tie-down attachment members are disposed on and mounted to upper end portions of the anchor rods with each tie-down attachment member having a tubular mounting body defining an axial passageway through which the upper end portion of one anchor rod extends and a retainer body disposed in an oblique relation and attached to the tubular mounting body. Each termination member is mounted to the upper end portion of one of the anchor rods. The endless strap has opposite portions secured to the tie-down attachment members and main portions laid over a top of and disposed in a substantially transverse relation to the pipeline and extending between and attached to the opposite portions. The retainer body of each tie-down attachment member defines an annular shoulder that overlies and encompasses one of the opposite portions of the endless strap so as to retain the endless strap n place over the top of the pipeline such that a buoyancy load of the pipeline is spread over the anchor rods and thereby reduces stress applied to the anchor rods.

Patent CA-2310190-A1 (CA)
Inventor: AZADET KAMERAN
IPC: H04L25/03
Filed: 2000-05-29
Abstract: A method and apparatus are disclosed for increasing the effective processing speed of a parallel decision-feedback equalizer by combining block processing and look-ahead techniques in the selection (multiplexing) stage. The present invention extends a parallel decision-feedback equalization by using look-ahead techniques in the selection stage to precompute the effect of previous blocks on each subsequent block, and to thereby remove the serial output dependency. The parallel decision-feedback equalization includes a multiplexor tree structure that selects an appropriate output value for each block and precomputes the effect of previous blocks on each subsequent block. A  multiplexing delay algorithm on the order of logN is employed to resolve the output dependency and thus speeds up parallel block processing decision-feedback equalizations. The disclosed decision-feedback equalization architecture can be combined with pipelining to completely eliminate the critical path problem. Pipelining reduces the required critical path timing to one multiplexing time. The disclosed multiplexor tree circuitry for the parallel decision-feedback equalizer groups multiplexor blocks into groups of two, referred to as block pairs, and provides at least one multiplexor for each block, i, to select an output value, y i, from among the possible precomputed values. The output of each parallel block depends on the possible precomputed values generated by the look-ahead processors for the block, as well as the actual values that are ultimately selected far each previous block. In order to reduce the delay in obtaining each actual output value, the present invention assumes that each block contains each possible value, and carries the assumption through to all subsequent blocks. Thus, the number of multiplexors required to select from among the possible values grows according to N-logN, where N is the block number.

Abstract: A continuous process for functionalizing polymers is disclosed, wherein (A) a liquid comprising the polymer and a gas comprising a functionalizing agent are continuously introduced into a dispensing zone operated in laminar flow with high intensity mixing of the liquid and the gas under functionalization conditions, wherein the mixing is conducted for a period of the dispersing zone residence time at a shear rate effective to form a stable gas-liquid dispersion in which the gas is substantially dissolved or dispersed in the liquid for functionalization, and wherein the shear rate is less than about 5 s-1 for no more than about 30 % of the residence time; (B) the gas-liquid dispersion is continuously passed to a blending zone operated in laminar flow with low intensity mixing under functionalization conditions, wherein the mixing is conducted at a shear rate effective to further dissolve the gas into the liquid for further functionalization; and (C) continuously recovering functionalized polymer. The process can be used to carbonylate unsaturated polymers, and is particularly useful in reacting unsaturated polymers with carbon monoxide in the presence of a catalyst and a co-reactant selected from water, H2S, alcohols, and thiols to produce functionalized polymer containing carboxylic (thio)acid or carboxylic (thio)ester functional groups.
