IPC: G02B6/34
Filed: 2002-06-06
Abstract: Dispersion compensation devices are described which comprise waveguides including sampled Bragg gratings which exhibit comb-like reflectance characteristics. The profile of effective refractive index along the length of the grating is controlled to adjust the position of the teeth and/or to control the dispersion exhibited by the device (i.e. to control the chirp of the grating). The devices can thus be used to provide dispersion compensation to any one of a number of wavelength channels in a WDM system.      In preferred arrangements, the effective refractive index distribution is set by a applying a temperature distribution along the length of the grating, or by setting an applied electric field,

Inventor: YLI-KOSKI ESKO
IPC: F16H57/12
Filed: 2000-11-29
Abstract: The present invention relates to a diaphragm actuator for control valves, wherein the gear rack is arranged so that the points of contact of the gear rack/gear wheel system are situated on the straight line connecting the centres of the movable walls of the pressure spaces effecting the movement. Thereby, no torsion forces act on the diaphragm backing plates or on the diaphragms, but the forces effecting the movement of the reciprocating elements are substantially parallel with the path of motion and symmetrical.    Additionally, the clearance between the gear rack and the gear wheel is substantially eliminated by means of a support roll with bearings.    According to the invention, a lightly movable actuator is provided, in which the delays caused by clearances or wall friction of the cylinder-piston arrangement are substantially eliminated. The actuator can be implemented either as double-acting or single-act-ing.

Title: Cell patterning technique
Inventor: JACKMAN REBECCA J
IPC: C12N1/00
Filed: 2001-03-15
Abstract: The present invention provides a masking system for selectively applying cells to predetermined regions of a surface. A mask is positioned adjacent to a surface to cover some portions of the surface while allowing other portions of the surface to remain uncovered. Cells then are applied to uncovered portions of the surface and the mask removed. Alternatively, a cell-adhesion promoter is applied to uncovered portions of the surface, and then cells are applied to the surface before or after removal of the mask from the surface. The masking system can be pre-coated, at least on those surfaces which will come into contact with cells, with a cell-adhesion inhibitor to resist absorption of cells and thereby avoid cell damage when the mask is removed (if cells are deposited prior to removal of the mask). A polymeric elastomeric mask that comes into cohesive-conformal contact with a surface to be patterned can be used.

Title: Method of and system for venting out buildup of explosive gases in a manhole
Inventor: KHAJAVI MOHAMMED B
IPC: E02D29/14
Filed: 2002-12-06
Abstract: A method of and system used for venting out buildup of explosive gases in a manhole caused by an explosion and including a support frame, a two inch thick plate member positioned on top of the support frame, a plurality of restraining assemblies and a manhole cover for covering the manhole. The support frame and the plate member are embedded into a street and positioned above the manhole, where openings are aligned with the manhole. Three retaining assemblies are positioned on opposite sides o.f the manhole cover. Each retaining assembly includes a rod, a stop plate, a coil spring, a support plate and a nut. The rod extends downwardly through the dirt and the horizontal concrete base ledge, where the stop plate, the coil spring, the support plate and the nut are positioned and secured to the other end of the rod. A PVC pipe is provided with the rod for allowing the rod to move smoothly up and down without any friction. When an explosion occurs in the manhole, the pressure caused by the explosion lifts the plate member from a seated position on the main support frame above the manhole which in turn upwardly moves the rod, the stop plate, the coil spring, the support plate and the nut, where the explosive gases are vented out between the plate member and the main support frame. The stop plate, coil spring, the support plate and the nut absorb most of the energy caused by the explosion. The spring soften the impact and assist in bringing the plate member back down to the main support frame in alignment with the manhole.
