Abstract: A composition of matter suitable for use in a reversible thermometer is disclosed which comprises a thermally responsive material capable of being supercooled at least for several minutes, and subject to a change in state from a solid to a liquid substantially at a predetermined temperature; means for visually observing the change in state; and a matrix forming material comprising an amorphous organic compound, the matrix forming material being insoluble in the thermally responsive material; whereby the thermally responsive material is dispersed within the matrix forming material, the composition of matter being reversibly responsive to changes in temperature, and remaining in the liquid state for a time sufficient to permit a user of the composition to observe the change in state. The preferred matrix forming material is polyisobutylene, and the preferred thermally responsive material is a solid solution of ortho-chloronitrobenzene and ortho-bromonitrobenzene.

Abstract: A magnetic security marker of an article surveillance system is deactivated by first determining the status of the marker by exposing it to the interrogating field. If the marker is active, a deactivation field is applied to the marker. The marker is again interrogated using the interrogating field and, if an active marker is detected, an incrementally increased deactivation field is applied. The marker is continually interrogated and, as long as an active marker is detected, the intensity of the field is incrementally increased until the field reaches a level effecting deactivation.

Abstract: There is provided a method for forming a nonwoven electret fiber filter with a nonwoven web of electret fibers needle-punched to an open scrim support. The scrim support material has individual discrete open areas with an average cross-sectional area as viewed from the plane of the filter media of at least 0.25 mm.sup.2, preferably 1.0 mm.sup.2, and a pressure drop across the scrim support, without the filter web, of less than 1.5 mm H.sub.2 O measured at 98.4 meters/min gaseous face velocity. The resulting filter has enhanced lifetimes, a low pressure drop and high filtration efficiencies.

Abstract: A drip resistant nozzle for a dispenser is described. The drip resistant nozzle includes a flexible, resilient member that moves between several positions during actuation of the dispenser.

Abstract: Composite films and film laminates comprising at least one elastomeric core and a surrounding nonelastomeric matrix preferably prepared by coextrusion. The film when stretched and allowed to recover will create an elastomeric composite.

Abstract: Acrylate copolymer pressure sensitive adhesives (PSAs) which incorporate relatively small amounts of a plasticizer are disclosed. The resulting PSAs exhibit improved low temperature performance and minimal effect on other properties, when used as adhesives for graphic marking films. The adhesive system has been found to allow the graphic marking film to be applied at temperatures as low as 20.degree. F. (-7.degree. C.) and to improve the ability of the film to be applied to a substrate without trapping air between the marking film and the substrate. The adhesive system of the marking film also demonstrates resistance to tenting around the compound curved surfaces of rivet heads and corrugations typical of truck trailer sides.

Abstract: A biomedical electrode is disclosed, having a geometry of conductive plates along a longitudinal axis of the electrode such that interior edge(s) of the plate(s) adjoining the axis are curvilinear or otherwise non-parallel to the axis. The geometry permits the electrode to register an earlier detection of a CQM alarm condition if a portion of the electrode unpeels from contact with the body of a mammalian patient before the extent of unpeeling would otherwise cause a CQM alarm condition established by and issued from an electrosurgical generator.

Abstract: Systems and methods of conditioning skin to reduce artifact in bioelectric signal monitoring by passing electrical energy into the skin through the medical electrodes. An electrode having electrolyte including an agent to reduce skin discomfort.

Abstract: A high-density optical fiber connector in which a plurality of ferrules containing the terminal ends of optical fibers are individually sprung and axially and transversely free to provide improved interconnection reliability. The present invention is a three component fiber optic connector for high density interconnection environments. The first component, a first male connector member, will typically be mounted on an edge of a generally planar substrate such as, for example, a circuit board, and includes a plurality of independently sprung, axially and transversely free optical fiber ferrules. The second component, a second male connector member, also includes a plurality of independently sprung, axially transversely free optical fiber ferrules. The third component, a coupling member, receives and couples together the first and second male members.

Abstract: A zoned inspection system and method produce inspection results consistent with a user's view of an article by transforming parallel, temporal inspection results from multiple detectors into a serial, spatial domain.

Abstract: A viral barrier composite of a thermoplastic film thermally bonded on at least one side thereof to a breathable thermoplastic web, and method for making the same. The viral barrier composite has viral barrier properties, a moisture vapor transmission rate of at least 700 g/m.sup.2 /24 hours and a bond strength between the thermoplastic film and breathable thermoplastic web of at least 0.07N/cm. The viral barrier composite is formed by calendering an assembly comprising a thermoplastic film and a breathable thermoplastic web between a smooth roll and a pattern roll. The viral barrier composite may be used for constructing articles of protective apparel.

Abstract: A polymerized microemulsion pressure sensitive adhesive composition is described. The composition has peel adhesion of at least 3 Newtons/100 mm as measured according to a PSTC-1 Test. The composition preferably has a bicontinuous structure of a continuous phase of a hydrophobic pressure sensitive adhesive polymer and a continuous phase of a hydrophilic polymer. The bulk properties of both polymers are retained in the bicontinuous structure. The composition is prepared from a microemulsion comprising a free-radically ethylenically unsaturated polar amphiphilic or hydrophilic monomer or oligomer in the aqueous phase, a free-radically ethylenically unsaturated hydrophobic monomer, having a glass transition temperature suitable for forming a pressure sensitive adhesive, in the oil phase, water, and surfactant.
