Abstract: An apparatus and method for windlocking a curtain (100) over an opening in a  building is disclosed and claimed. The windlocking curtain (100) resides to the exterior of the window, door or other opening and protects it from the intrusion of air, water or debris. In its upper position the windlocking curtain (100) permits normal use of the opening and in its lower position it  secures the opening. A flexible corrugated curtain (115) has tension rods (123, 124) therethrough and the tension rods (123, 124) run in tracks (111, 112) on each side of the curtain (115) and necessarily on each side of the opening. Interengagement of the tension rods (123, 124) with tracks (111, 11 2) is accomplished by deformations in the rods that are referred to as interrup ts (121). In one embodiment the tension rods (123, 124) are successively longer  from top to bottom of the curtain (115) and their interrupts matingly wedge with angled tracks (111, 112) to secure the curtain (115). In another embodiment the interrupts (705, 707, 710) matingly engage parallel tracks (602, 603) upon the application of force due to wind, fluid (usually water o r sea water) or debris. In another embodiment a flap on the edges of a flexibl e curtain (2200) engage the side tracks (2204) absorbing shocking and sealing the opening. A method for securing the opening utilizing the apparatus is al so claimed which provides top, bottom and side securement.

Abstract: A tool for removing damaged fasteners and a method for making such tool wherein the tool (10) includes a first end (12) and a second end (14) with an outside surface (32) and an inside surface (40) defined between ends (12) and (14). A portion (46) of inside surface (40) is in the shape of an hexagonal frustum (54) that has a major end (58) and that includes spiral splines (25).  Splines (25) have constant depth between the major end (58) and the minor end (56) of frustum (54) and the relief angle (AE) of splines (25) decreases in the direction from minor end (56) toward major end (58). In the method for making the tool (10), a tubular section (118) is made from a tapered blank (91) by piercing one end of the tapered blank with a pierce punch (132). One end of the tubular section is then driven onto a splined punch (162) to provide splines in one end of the tubular section. The tubular section is then stripped off of the punch (162) by a kickout sleeve (166) and extruded through a round-to-hexagonal extrusion insert (182) to provide portion (46) of the inner surface (40) with a tapered, hexagonal shape.

Title: Electron-driven chirality switches
Inventor: CANARY JAMES W
IPC: C07F1/08
Filed: 2000-07-26
Abstract: Complexes of organic ligands with a metal ion exhibit unique conformation and spectroscopic properties upon changes in oxidation state of the metal ion. The metal is a redox-active metal ion and may possess additional ligands bonded to it. The organic ligand has three "arms" that are linked together at a central atom; each arm contains atoms that may also coordinate to the metal ion. At least two of the arms possess chromophoric properties. At least one arm contains two different groups that may coordinate to the metal ion. In one oxidation state, a first atom binds to the metal. In a second oxidation state, a second atom binds to the metal. This change in coordination of the metal ion results in a rotation of one of the arms, which changes the orientation of another group, which inverses the orientation of the two chromophoric species with respect to one another.

Title: Method for finding the reflectivity of reflectors
Inventor: VINJE VETLE
IPC: G01V1/28
Filed: 2001-05-22
Abstract: Method for solving the classical inversion problem of finding the angle dependent reflection coefficients along selected reflectors in the subsurface.  The input data to the method include seismic constant offset or constant angle data cubes from Pre-Stack Depth Migration of Kirchhoff type and the corresponding reflectors and velocities from the interpretation and velocity analysis of the data. One or more of the reflectors are chosen and ray modeling is done to create synthetic seismics for all shot/receiver pairs in the seismic survey. Based on these modeling results, amplitude correction maps are made for the various reflection angles. These correction maps are applied to the amplitudes from the seismic data. The corrected amplitudes are approximations to the angle-dependent reflection coefficients in all points on each selected reflector. For each point, a weight function is computed, giving the quantitative resolution of the estimate of the reflection coefficient.
