Title: Scrim-like paper wiping product and method for making the same
Inventor: ANDERSON RALPH L
IPC: D21H15/10
Filed: 1998-04-27
Abstract: The present invention is generally directed to single ply scrim-like wiping products having great softness and strength. The wiping products are made from a paper web containing softwood fibers in combination with bicomponent fibers. Once formed, the paper web is treated on each side with a bonding agent in a preselected pattern. At least one side of the paper web is also creped. In order to create a wiping product with a scrim-like appearance, a reticular pattern is then embossed into a paper web. Specifically, the pattern is permanently imprinted into the product by compressing and fusing together the bicomponent fibers contained within the lines of the pattern.

Patent CA-2299402-A1 (CA)
Inventor: LIU JIAN-YU
IPC: H04B10/29
Filed: 1998-07-28
Abstract: An optical cross-connect network provides wavelength routing of optical channels between two arrays of optical fibers carrying WDM signals using interconnected arrays of optical wavelength switches based on combinations of a 1 x 2 wavelength switch architecture. The cross-connect network can be made by interconnecting two arrays of 1 x 4 wavelength switches (10, 20), each of which is made by combining three 1 x 2 wavelength switches (11, 12, 13). Each 1 x 2 optical wavelength switch includes a polarization separation element (3) that decomposes and spatially separates the input signal into two orthogonallypolarized beams, and a wavelength filter (61) that decomposes into the beam pair into two pairs of orthogonally-polarized beams that carry a first spectral band at a first polarization and a second spectral band at an orthogonal polarization. A polarization-dependent routing element (50) spatially separates these four beams into four orthogonally-polarized components. A polarization combining element (70) recombines the beams carrying the first spectral band, and also recombines the beams carrying the second spectral band at the output ports based on the control state of the wavelength switch.

Title: Anti-rotation clips
Inventor: DUTTON COLIN
IPC: F16B39/10
Filed: 2000-11-17
Abstract: An anti-rotation clip is adapted to be attached to a fastener or connector assembly to ensure the tightened threaded connection of the assembly. The anti-rotation clip in one embodiment of the invention includes one or more co-axial clips to radially and forcibly grip one or more hexagonal parts rotatable to a body, and a pair of tang members extending from one clip to engage a pair of grooves having flat bottoms on the body to prevent the hexagonal parts from rotation and the clip from axially moving away relative to the body. In another embodiment of the invention, two co-axially connected clips are adapted to radially and forcibly grip two connectors, having hexagonal exteriors, which are in a tightly threaded connection to a body and may be loosened in opposite rotary directions. The two clips lock the two connectors together to prevent the loosening of either one. An axially spaced apart tang member restrains a flange member on the body to prevent the clip from displacement from its axial position. The anti-rotation clip is simple in structure, easy for use and no plastic deformation is required during installation so that stress concentration is avoided which is especially good for aerospace applications.
