Patent CA-2356770-A1 (CA)
Title: Cornice or crown molding finishing accessory
Inventor: WATSON TOM
IPC: E04F19/04
Filed: 2001-08-30
Abstract: A cornice or crown molding finishing accessory (10) allows creation of a smooth, continuous and aesthetic finish to the joint between first and second molding segments. These molding segments may be oriented to form inside or outside corners. Preferred examples of the finishing accessory are adapted for use with outside and inside 90 degree corners. The molding finishing accessory provides first and second facade-creating flanges (20), (40) which have a cross-sectional shape including a molding-conforming curve designed to match the cross-sectional decorative surface of the molding segments. The flanges meet at a vertex (60), from which an anchor element extends. In use, the anchor element (80) is inserted into a gap defined between the first and second molding segments, thereby holding the finishing accessory in place. A thin layer of drywall "mud" is brushed over flanges of the finishing accessory and adjacent areas of the molding segments, thereby smoothing over any lines of transition between the finishing accessory and the molding segments. The resulting appearance is that of a perfect transition between the first and second molding segments, and complete masking of the gap between these segments.

Inventor: MAASKANT ROBERT
IPC: G02F1/01
Filed: 2000-03-10
Abstract: The present invention provides a mechanism for controlling the tension of a guided wave fiber Bragg grating (12) device. The tension imposed on a guided wave fiber Bragg grating (12) can be used to control its spectral characteristics as desired. For example, the center wavelength of a fiber Bragg grating (12) can be directly controlled by the tension imposed on the fiber, and in the case of a nonlinearly chirped grating, its effective group delay properties can also be controlled by fiber tension. These examples are directly related to applications in sensing, and in WDM filters and dispersion compensation devices. The tension control mechanism for controlling the spectral properties of a fiber Bragg grating (12) includes a support structure (18) to which the fiber Bragg grating (12) is attached at a first (20) and second (22) portion. The support structure (18) includes an adjustment mechanism (30) whereby adjustment of the support structure in one direction increases tension in the fiber Bragg grating (12) and adjustement of the support structure (18) in the other direction decreases tension in the fiber Bragg grating (12).
