Abstract: Stretchable film laminates including a layer of elastomeric openwork, such as a plurality of elastic strands or an elastomeric mesh structure. The stretchable film laminates may include a film layer bonded to the layer of elastomeric openwork, with the film layer having cross-directional stretch and the laminate having a multi-phase stretchability profile. The stretchable film laminates may be made by extruding a film from a die, stretching the film, forming and stretching a layer of elastomeric openwork, conveying the stretched elastomeric openwork onto the film while the film is stretched, and passing the film and the elastomeric openwork through a nip. The invention also includes a machine capable of producing machine-direction, cross-direction, and biaxial stretch materials. The machine includes at least one extruder, at least one filament die and at least one film die both attached to the extruder(s), and at least one nip downstream of the extruder(s).

Abstract: A method for protecting a surface of an article includes preparing or otherwise providing a reactive solution of a form of polyaniline and an acid, thereafter applying the reactive solution to the surface of the article to form an adherent conversion coating on the surface, thereafter oxidizing the adherent conversion coating to form an oxidized coating, and thereafter contacting a chromate-free, corrosion inhibiting organic compound such as a salt of a dithiocarbamate or a salt of a dimercaptothiadiazole to the oxidized coating to form a fixed conversion coating on the surface of the article. The resulting article has the fixed conversion coating adhered to the surface of the article. The fixed conversion coating has a mixture of a reduced polyaniline salt, and a fixed disulfur-linked dithiocarbamate polymer or dimer.

Abstract: The present invention increases the pumping efficiency when pumping liquids whose liquid source is at a temperature and pressure close to the liquidus, or having entrained gas or gas coming out of solution, referred to as vapor, in several ways. First, the pump is oriented to allow liquid flowing into the compression chamber by the natural tendency of liquid to flow downward and residual vapor to return to the supply tank, by the natural tendency of vapor to flow upward. The location of the large smooth inlet line at the top of the pump encourages any vapor to escape and be piped back to the supply tank. The flow of vapor back to the supply tank is also encouraged by the vapor outlets and conduit leading back, at a positive slope, to the supply tank. Second, the inlet chamber located above the inlet valve reduces cavitation because this chamber prepares a new discrete volume of inlet liquid while the current discrete volume is being power-stroked out of the compression chamber.

Abstract: An optical modulation device includes an electrolyte containing electrodepositable metal ions sandwiched between a conducting polymer counter electrode and an optical modulation electrode involving reversible metal electrodeposition. The conducting polymer counter electrode does not generate mobile reactive species, and avoids the light blocking associated with grid or dot matrix electrodes involving reversible metal electrodeposition. A polyaniline counter electrode in a smart window device employing a reversible electrochemical mirror modulation electrode provides high light transmission, fast switching, and coloration to mask the backside of the mirror electrode.

Abstract: A polymer composite structure, wherein the composition releases an anionic dopant upon application of an electrochemical potential, such as when in contact with a metallic substrate in a corrosive environment. The composite actively inhibits corrosion at the point of contact of the composite with a metal substrate by release of “active” or “smart” corrosion inhibitors which migrate to the corrosion area. Composites having anionic dopants having biocidal or scale-inhibiting properties may be used to inhibit biofouling and scaling wherein the dopants are released upon application of a electrochemical potential.

Abstract: A film which may be placed on a metallic substrate to inhibit corrosion of the substrate when in a corrosive environment. The film also inhibits corrosion at a defect area in the film when the substrate is exposed in the presence of a corrosive environment. The film includes dopants which release from the film when corrosion begins at a film defect. Therefore, the film not only inhibits corrosion where the film is undamaged, but also inhibits corrosion at the site of a defect in the film. Advantageously, the system does not lose its effectiveness over a given period of time if no defect occurs in the substrate.

Abstract: A fire retardant polymer composition is provided. The fire retardant polymer composition is formed of a polymer material and a polycondensation product of a plurality of monomers of an at least partially hydrolyzed phosphinate-chelated metal oxide precursor. A process for making a flame retardant polymer composition is also presented. The process includes contacting a metal oxide precursor with a source of organophosphinate anions to form a phosphinate-chelated metal oxide precursor. The phosphinate-chelated metal oxide precursor is at least partially hydrolyzed and then condenses to form a phosphorous-containing metal oxide sol. The sol may be contacted with a polymer material, which is then polymerized or solidified.

Abstract: An extensible laminate includes a sheet of an extensible nonwoven material that has a fabric side and a film side, a sheet of an elastomeric film, and an adhesive. The adhesive is applied to at least a portion of the film side of the extensible nonwoven material. The extensible nonwoven material is selectively attached to the elastomeric film by a plurality of intermittent adhesive bonds. The extensible nonwoven material is further selectively attached to the clastomeric film by a plurality of thermal point bonds. The intermittent adhesive bonds cover a greater percentage of an interfacial plane between the extensible nonwoven material and the elastomeric film material than the thermal point bonds. A process for making the extensible laminate is also disclosed.

Abstract: A film which may be placed on a metallic substrate to inhibit corrosion of the substrate when in a corrosive environment. The film also inhibits corrosion at a defect area in the film when the substrate is exposed in the presence of a corrosive environment. The film includes dopants which release from the film when corrosion begins at a film defect. Therefore, the film not only inhibits corrosion where the film is undamaged, but also inhibits corrosion at the site of a defect in the film. Advantageously, the system does not lose its effectiveness over a given period of time if no defect occurs in the substrate.

Abstract: A telecommunication screening system for screening phone calls prior to initiating an incoming call signal and for tracking the number of screened calls. The telecommunication screening system includes a device connectable to a phone line between an outlet and a telephone. The device would answer an incoming call and play a message identifying calls that are unwelcome then offer to pass the call through to the phone upon entry of a requested number by the caller. Upon input of the requested number, a signal will be sent through to the phone to ring the phone and connect the caller upon a user answering the phone.

Abstract: Disclosed herein is a liquid absorbent material that is particularly useful as a liner material for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like. The material contains a plurality of peaks across its surface at spaced-apart intervals separated by channels. Disposed within the peaks is a liquid absorbing material capable of absorbing body exudates and liquids in general. Due to the materials and the nature of the construction of the present invention, when used as a liner material for personal care absorbent articles such as diapers, it tends to reduce the total surface area in contact with the infant's skin and it also provides a plurality of air channels within the diaper from the front waistband to the back waistband of the diaper thereby providing a path for increased air circulation.
