摘要:
This invention provides methods and processes to attach or bond hydrogels to suitable surfaces using irradiation techniques and also provides methods and processes to create crosslinked regions in hydrogel articles using these irradiation techniques. Specifically, lasers at wavelengths tuned to the irradiation absorption bands of hydroxyl groups, carboxylic acid groups or water may be used to attach or bond hydrogels to surfaces such as soft tissue and hydrogel surfaces or to crosslink regions in hydrogel articles.

A wrapped article (20) includes a personal care absorbent personal care article (22), and a separately provided wrap member (24) which operatively encloses the absorbent personal care article (22). At least a major portion of the wrap member (24) includes an outer layer (26), an inner layer (28) and an intermediate layer (30) that is sandwiched between the inner and outer layers, and includes an operative amount of an odor control agent (32). In particular aspects, the intermediate layer (30) can include a nonwoven fibrous web, and the fibrous web can have selected fiber sizes. In another aspect, the intermediate layer (30) of the wrap member (24) can include a meltblown nonwoven web. In further aspects, the outer layer (26) can include a nonwoven fibrous web having particular fiber sizes, and the inner layer (28) can include another nonwoven fibrous web having the same or different fiber sizes.

A protection circuit for use with a charger and a chargeable element, such as a rechargeable lithium ion battery, comprises a shunt regulator having a threshold ON voltage coupled in parallel across the chargeable element, and a temperature-dependent resistor, e.g., a positive temperature coefficient device, coupled in series between the charger and the chargeable element. The temperature dependent resistor is thermally and electrically coupled to the shunt regulator, wherein the first variable resistor limits current flowing through the shunt regulator if the current reaches a predetermined level less than that which would cause failure of the regulator, due to ohmic heating of the regulator.

Disclosed is a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith a yellow dye-forming coupler having formula I: wherein each A is independently a divalent group selected from the divalent groups consisting of aryl and —C(R1)(R2)—, in which each R1 and R2 is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryloxy, heterocyclic, and aryl groups, and one A can be joined to form a ring with another A or with R3, and m is from 2 to 6; R3 is selected from the group consisting of hydrogen, alkyl, heterocyclic, and aryl groups, provided that R3 may form a ring with A or is a group joined to R4 to form a heterocyclic five- or six-membered ring; R4 is selected from the group consisting of aryl, heterocyclic, and alkyl groups and may form a heterocyclic ring bonded to R3; Y is selected from the group consisting of —SO2—, —C(═O)—, —C(═O)NR9R10—, —C(═O)O—, and —P(═O)(OR9)(OR10—) where R9 and R10 are independently H or an alkyl or aryl group; and the remaining substituents are as described in the summary of the invention.
摘要:
The invention provides photographic paper having increased image stability. The invention is generally accomplished by forming a paper sheet, drying said paper in a first stage to below about 10 percent water, then applying a polyvinyl alcohol solution to both sides of said paper sheet, drying said paper in a second stage to below about 5 percent water, and then applying further polyvinyl alcohol solution to said paper and drying in a third stage. The paper then may be coated to form a silver halide photosensitive color paper. The paper contains between about 4 and about 6 weight percent of polyvinyl alcohol that is concentrated near the surface of said paper. Further, the paper has a oxygen leak rate of less than about 25 cc/m.sup.2 /day and an oxygen GTR rate of less than about 1 cc/m.sup.2 /day.

摘要:
The method and system of the present invention provides an improved technique for replacing, implementing and managing computer-related assets. A technician accesses the World Wide Web through a user's computer. The information resident on the computer, including information regarding the computer and the user's preferences, are downloaded to a remote storage medium through the World Wide Web. Once downloaded, all information may be removed from the user's computer. Subsequently, the technician accesses another computer such as, for example, a new computer that has been assigned to the same user. The technician accesses the World Wide Web through the new computer and downloads the information previously stored on the remote storage medium. This information can then be used to install the user's prior applications, settings and preferences on the new computer.
摘要:
Various embodiments of optical fiber designs and fabrication processes for ultra small core fibers (USCF) are disclosed. In some embodiments, the USCF includes a core that is at least partially surrounded by a region comprising first features. The USCF further includes a second region at least partially surrounding the first region. The second region includes second features. In an embodiment, the first features are smaller than the second features, and the second features have a filling fraction greater than about 90 percent. The first features and/or the second features may include air holes. Embodiments of the USCF may provide dispersion tailoring. Embodiments of the USCF may be used with nonlinear optical devices configured to provide, for example, a frequency comb or a supercontinuum.
摘要:
An image receiving element is a composite of multiple layers on a support including, in order, an extruded compliant layer, an aqueous-coated subbing layer, and an image receiving layer that may also be extruded. The extruded compliant layer is non-voided and comprises from about 10 to about 40 weight % of at least one elastomeric polymer. This image receiving element can be disposed on a support to form a thermal dye transfer receiver element, an electrophotographic image receiver element, or a thermal wax receiver element. Excellent adhesion is provided between the extruded compliant layer and the image receiving layer by means of the aqueous-coated subbing layer.
