Abstract:
An open cell foam bulk absorber is formed by pressurizing a foaming agent and a foamable material, and then decompressing the foaming agent and the foamable material. During decompression, the foamable material and foaming agent expand, and a plurality of open cells are formed in the foamable material, thereby producing an open cell foam bulk absorber. The open cells in the bulk absorber have a distribution of sizes about a mean size, and a density gradient.
Abstract:
A display includes an optical film that has a surface structure, such as a prismatically structured surface for increasing the brightness of the display. The structured surface is bonded to an opposing surface of a second film using a layer of adhesive, by penetrating the structured surface into the adhesive layer to a depth less than a feature height of the structured surface. The bonded film structure provides additional strength to the films and reduces the possibility of film damage during display assembly.
Abstract:
A peelable lidstock for use with a child resistant pharmaceutical blister is disclosed. The lidstock includes a first layer of white polyester, a second layer of adhesive, a third layer of foil, and a fourth layer of heat seal. The lidstock is strong and provides excellent child resistance and a broad sealing window which facilitates manufacture.
Abstract:
A diaphragm is provided that includes a tubular sidewall and a first elastomeric material. The tubular sidewall has an open end and an enclosed end and comprises fabric having a plurality of yarns disposed in a bias weave pattern. The first elastomeric material is disposed over the fabric at a predetermined thickness.
Abstract:
Methods of making articles are disclosed, which include pressing a solidifiable material against a structured surface of a film to impart surface structures in the solidifiable material. The methods further include solidifying the material so pressed, which may be provided on a substrate, to produce a second film having a structured surface that releaseably mates with the structured surface of the first film.
Abstract:
Injection molding systems and methods useful for making microcellular foamed materials are provided as well as microcellular articles. Pressure drop rate and shear rate are important features in some embodiments, and the invention provides systems for controlling these parameters in an injection molding system. Another aspect involves an injection molding system including a nucleator that is upstream of a pressurized mold. Another aspect involves an extrusion system with the reciprocating screw for forming a single phase solution of non-nucleated blowing agent and polymeric material. Another aspect involves very thin walled microcellular material and very thin walled polymeric material. Another aspect provides a method for producing high weight reductions in very thin-walled parts with surfaces that have no noticeable differences from non-foamed parts.

Abstract:
A systems-assisted method for defining and managing a public value network according to one or more desired outcomes of the public value network, which includes creating a public value network representation by defining participants in the network, relationships between the participants, and a desired outcome the network, assigning a maturity level value to each relationship; establishing a network governance framework; specifying the capabilities of said public value network; calculating a capabilities maturity index according to the defined relationships, relationship maturity levels, and capabilities; and creating visualizations displayed to a user representing the network, the relationships, and the maturity levels.
Abstract:
A method is provided for repairing a defect in a noise suppression panel. The method may be used to repair defects in a panel that may occur during the manufacture of or normal use of the panel. The method includes the steps of removing the defect from the noise suppression panel to create a cavity therein, forming material comprised of a material having acoustic damping properties into an insert configured to mate with the cavity, and placing the insert into the cavity.
Abstract:
A guitar bridge bias converter is described which provides the means of converting a right-handed steel strung electric or acoustic guitar to a left-handed instrument. The bridge bias converter for an acoustic guitar consists most simply of an integral one-piece unit comprising a central plate, a lower tongue, and an upper bridge-bone. The tongue locates in the groove vacated by removal of the original right-handed bridge-bone. The plate sits on top of the bridge and the bridge-bone is situated on the plate at an angle which is diametrically opposed to the original bridge-bone. This has the effect, in conjunction with reversal of the string positions, of converting the guitar from right-handed to left-handed playing. An alternative embodiment appropriate to conversion of electric guitars is also described, comprising a replacement bridge block incorporating mounting hole protrusions so offset as to convert the instrument from right-hand to left-handed string bias. It is an important feature of the invention that it requires no change to the body of the instrument and that the conversion process is completely reversible.
