Abstract:
The invention relates to a flushable paper product comprising a fibrous substrate having (i) at least one strength region comprising a reacted cationic or a reacted nonionic strength agent and (ii) at least one dispersibility region, wherein the paper product has (a) a dispersibility of at least one tenth of a second, (b) a dry strength, and (c) a wet strength of at least about five percent of the dry strength.
Abstract:
The invention relates to a composition comprising a (a) a temporary wet strength agent component capable of forming hemi-acetal bonds with the fibers of a tissue web to provide initial wet strength, subsequent rapid degradation of the initial wet strength when the tissue web contacts water; and (b) a sizing agent component capable of imparting water-repelling properties to the tissue web; such that the strength agent component and the sizing agent component are present in sufficient amounts so that when the composition is added to a tissue pulp slurry during a tissue-making process, tissue made from the tissue-making process exhibits a combination of (1) improved initial wet tensile, (ii) improved decay, and (iii) absorbency.
Abstract:
The invention relates to a composition comprising (a) a functional promoter comprising a water-soluble anionic polymer having a molecular weight of at least about 50,000 daltons and a molecular weight charge index value of at least about 10,000; (b) a cationic surfactant component; such that when the composition treats a fibrous substrate, in conjunction with a cationic strength agent, the treated fibrous substrate exhibits (i) a ratio of wet tensile strength to dry tensile strength ranging from about 1:5 to about 1:2 and (ii) an increase in a ratio of wet tensile strength to dry tensile strength of at least about 10%, as compared to when the fibrous substrate is treated with the functional promoter and without a surfactant. The invention also relates to a paper product made with such a system, and method for imparting wet strength to a paper product with the functional promoter.

The display has a first side and a second side wherein the first side and second side are substantially parallel The display includes: a single substrate, a self-sealing electrolyte layer, a coloring electrode, a second electrode and an insulator layer. The single substrate forms the first side of the display with the self-sealing electrolyte layer forming the second side of the display. The insulator layer is positioned between the coloring electrode and the second electrode and the coloring electrode, second electrode and insulator layer are positioned between the first and second aides of the display The self-sealing electrolyte contains a polymer and electrolyte and at least some portion of electrolyte from the self-sealing electrolyte layer permeates throughout the layers of the display. The display may include a self assembling layer formed from micron sized and nanometer sized particles to form an electrically conductive layer and/or a conductive plus capacitive layer.
Abstract:
A control system (100) for controlling movement of a medical device delivery system, a stent delivery system and a method for controlling movement of a medical device delivery system are provided. The control system includes a rotatable gear (122) operably connected to a first movable member (116) and a second movable member (118) movable by the rotatable gear. The first movable member is operably connected to the first shaft (22) and the second movable member operably connected to the second shaft (24). The first movable member moves the first shaft and the second movable member moves the second shaft to change a position of the first shaft relative to the second shaft and to change a configuration of a medical device operably connected to the first shaft and the second shaft.

In one preferred embodiment, the stent contains one or more circumferential rows of uncovered cells located between two or more circumferential rows of covered cells (120). In some embodiments, the stent may have a central body portion (108) and one or more flanges (110, 112) where the circumferential rows of uncovered cells may be located within the flange (s).
Abstract:
Communicating between stations over a shared medium includes: monitoring the shared medium for signals received at a first station that is identified with a local network; storing information at the first station that represents characteristics of the signals received at the first station associated with capacity of the shared medium; monitoring the shared medium for signals received at a second station that is identified with the same local network as the first station; storing information at the second station that represents characteristics of the signals received at the second station associated with capacity of the shared medium; and determining whether a stream of data is allowed to be transmitted over the shared medium between the first station and the second station based on at least one of the stored information from the first station and the stored information from the second station.
Abstract:
A new process to make high solids polymer backbone with low molecular weight and narrow molecular weight distribution has been developed by a continuous polymerization processes under refluxing conditions. In this process, a mixture of acrylamide monomer, chain transfer agent and initiator is simultaneously and continuously added to the heel of aqueous solution under refluxing conditions.
Abstract:
An electrochromic reflective display device and method for fabricating same. The device includes a plurality of patterned areas, redox chromophore moieties, electronic circuitry and a common electrode. The plurality of electrically discrete patterned areas includes a metal oxide having a surface area of at least 97 meters square per gram of metal oxide said metal oxide. At least 12 nmols of redox chromophore moieties per square centimeter area per micron of thickness of the metal oxide are absorbed to each of the patterned areas. The redox chromophore moieties in each patterned area vary color of absorbed light as the redox chromophore moieties in the patterned area transition from a first redox state to a second redox state. The electronic circuitry, coupled to each of the patterned areas, selectively transitions the redox chromophore moieties in each of the patterned areas between the first redox state and the second redox state.
