Abstract: A fibrous sheet is provided with an outer surface having fibrous elements which are embossed with a pattern of fine grooves that are substantially aligned from fibrous element to fibrous element. The pattern of fine grooves is embossed directly on the surface of the fibrous sheet and produces rainbow and/or hologram images on exposure to light. In contrast, prior fabrics for producing rainbow or hologram images were laminated to plastic or metal foils having pre-embossed patterns of grooves. Sheets and fabrics of the present invention are free from such impermeable foils and retain desirable attributes of breathability and other aesthetic qualities.

Title: Clamp for holding flat objects
Inventor: MEIER JACQUES
IPC: B65H29/04
Filed: 1998-05-05
Abstract: The invention relates to a clamp (10) for holding sheet-like objects, having a support (12) on which a clamp tongue (20) is fixed. A clamping jaw (32) is stored in a guide slot (30) in the support (12) in such a way that it can move both in and against the direction of closing (S). When the clamping jaw (32) moves from open position (34) in closing direction (S), the clamp end (42) is displaced along the path of movement (46), until it rests against the clamp tongue (20) or an adjacent object. As the clamping jaw (32) continues to move in closing direction (S), the clamp end is driven back from the path of movement (46), and a clamping force for holding the object is formed as a result of the elasticity of the clamping jaw (32).

Inventor: SHEVCHUK GEORGE JOHN
IPC: G02B6/00
Filed: 2000-06-06
Abstract: The invention relates to plastic optical fiber (POF) processes and systems and involves improved non-polishing termination techniques.      The techniques provide good physical and optical characteristics, i.e., smoothness, at the termination point, thereby providing lower losses than conventionally obtained. According to one embodiment, POF is cut while the fiber is under compression. According to another embodiment, the POF is notched and then pulled at a relatively high strain rate to induce fracture. The rate is such that the strain remains in the elastic region, i.e., the fiber exhibits brittle, as opposed to ductile, behavior during the strain. The brittle behavior provides a smooth termination surface, as opposed to a plastically-deformed surface.
