In accordance with the invention, an optical fiber is provided with a protective polymer coating that is substantially free (less than 0.1% by weight and preferably 0%) of adhesion promoters and coupling agents. Advantageously, in lieu of adhesion promoters, the primary polymer coating formulation is provided with an additive which will covalently bond with the fiber but not with the primary polymer.

The present invention relates to an enhanced exclusion filter having a cylindrical stack of substantially identical annular disks and a central rotating element. Each annular disk engages the rotating element by at least one strut which extends inward from the inner perimeter of the annular disk toward the central axis of the cylindrical stack. Protuberances extend from the annular disks and engage depressions in adjacent annular disks to maintain the spacing between adjacent annular disks. Dimples extending through the annular disks may be utilized to form a depression on one surface of an annular disk and a protuberance on the opposite surface of the annular disk. The annular disks are angularly offset by a fixed amount from the adjacent annular disks so that rough vane surfaces are formed by the struts of the annular disks. Preferably a pattern of substantially identical angular offsets is used. In the alternative, a pattern of angular offsets may be used in which series of small angular offsets are separated by large angular offsets in a direction opposite from the small angular offsets. Preferably, the design of the struts is modified so that the trailing and leading edges of the struts extend toward adjacent struts, forming more continuous vane surfaces. The present invention also relates to the use of exclusion filters as a means of providing a flow of fluid through electronics enclosures. The present invention also relates to the use of redundant pressurized enclosures comprising an enclosure casing, two exclusion filters, and two pressurizing means. The enclosure casing has a major orifice through which fluid enters the enclosure casing and a minor orifice through which fluid exits the enclosure casing. The pressurizing means discharge filtered and pressurized fluid in two discharge areas within the enclosure casings which are substantially opposite from one another.

A method for making a device in which a conductive polyaniline layer (polyaniline salt layer) is formed on a substrate and patterned into a desired configuration, is disclosed. The polyaniline salt containing layer is formed by applying a polyaniline salt solution which combines a mixture of polyaniline and an additive, dissolved in a solvent on the substrate. Thereafter, the polyaniline salt containing layer is patterned by delineating in such layer at least one region having a conductivity less than about 10.sup.-6 S/cm. The at least one region in the polyaniline salt containing layer having a conductivity less than about 10.sup.-6 S/cm is optionally formed by combining a photobase generator (PBG) with the polyaniline salt solution. An adhesive is optionally mixed with the polyaniline salt solution for forming an polyaniline salt/adhesive polymer layer which is patterned into the desired configuration.

Siloxane compounds formed by the reaction of a hydridosiloxane with vinylsiloxane are employed in a wide variety of uses, e.g., coatings for optical fibers and flexible layers for touch screen cathode ray tubes. These siloxane materials are substantially improved through treatment with a lower alkene such as ethylene to prevent hydrogen evolution and undesirable crosslinking.

A resilient and deformable touch screen that is adapted to be overlaid on the surface of a CRT screen is formed from a semi-rigid plastic frame attached to a flexible plastic pouch filled with a soft resilient material which adheres to the surface of the pouch.
