Patent CA-2248747-A1 (CA)
Title: Methods and systems for forming multi-filament yarns having improved position-to-position consistency
Inventor: KING WILLIS M
IPC: D02G3/34
Filed: 1998-10-14
Abstract: Individual differently colored or colorable feed filament ends are withdrawn from respective creel-mounted packages and passed through a separation guide. The separation guide serves to "normalize" the filament end-to-end positions and tensions. That is, the separation guide will cause the individual feed ends to be in specific predetermined positions relative to the other feed ends regardless of the position of the package on the creel. In addition, the separation guide will effectively cause a short length of each feed end to be parallel to, and separated by a substantially uniform distance from, corresponding lengths of the other feed ends. This parallel alignment of individual end lengths and the substantially uniform filament end-to-end positioning thereby imparts substantially uniform tensions on the feed ends while substantially maintaining their respective positions in the combined yarn product relative to one another. The position- and tension-normalized feed ends are thereafter immediately passed from the separation guide to an interlacer. The interlacer serves to positionally lock the combined feed filaments to one another so that substantially no filament end migration will ensue as the combined yarn is further processed (e.g., during downstream draw-texturing operations).

Title: Expandable belt and tread drum
Inventor: BYERLEY MARK S
IPC: B29D30/24
Filed: 1999-06-11
Abstract: A belt and tread drum having an annular shell comprising a plurality of circumferentially spaced segments, each of which is mounted on a carrier which disposed in circumscribing relationship to a generally cylindrical actuator rotatably connected with a reciprocating piston disposed within a cavity defined between the actuator and a hub fixed to a central core of the drum. Translational movement of the piston between extended and retracted positions in a direction parallel to the rotational axis of the drum is converted into selected rotational movement of the actuator relative to the hub. A plurlaity of sets of links interposed between the segments and the actuator and hub have their first ends commonly pivotally pinned to a segment. The second end of one link of each set of links is pivotally pinned to the actuator and the second end of the other link of each set of links is pivotally pinned to the hub. Rotation of the actuator relative to the hub controls the arcuate separation of these second ends such that bringing these second ends toward contiguity moves the segments radially outwardly, and conversely, moving these second ends arcuately apart serves to move the segments radially inwardly of the drum. A hand wheel establishes maximum and minimum rotational movement of the actuator and provides a visual indication of the radial positions of the several segments, i.e. the diameter of the drum.

Title: A method and an arrangement for despreading a coded sequence in a communication system
Inventor: POPOVIC BRANISLAV
IPC: H04B1/707
Filed: 1997-12-19
Abstract: The invention relates to a method and an arrangement for implementing a bank of correlators, corresponding to a set of Orthogonal Gold codes, in a receiver used in a Direct Sequence Code Division Multiple Access system (DS-CDMA). The bank of correlators generates N correlation values (CV0,...,CVN-1) from N  received symbols (s0,s1,...,sN-1) in a sequence. The received symbol sequence (s0,s1,...,sN-1), where each symbol has been spread by an Orthogonal Gold code respectively, is buffered (401). The buffered symbol sequence is multiplied (402) element-by-element with an arbitrary sequence (a0,a1,...,aN-1), in order to obtain a set of products (s0*a0,s1*a1,...,sN-1*aN-1). Said arbitrary sequence is the same sequence used when generating the Orthogonal Gold Codes.  The set of products (s0*a0,s1*a1,...,sN-1*aN-1) is then permuted (403) in order to obtain a sequence, which is equal to a sum of a number of sequences from a set of Walsh sequences. The sequence is then transformed (404) with Fast Hadamard Transform as to obtain said correlation values (CV0,...,CVN-1).
