Abstract: A method of forming a metallic container includes the steps of providing body and lid portions, placing the body and lid portions together, keeping portions of the body and lid portions in contact with one another, and reciprocally rotating the lid portion with respect to the body portion, thereby generating frictional heat and forming a friction weld therebetween. An apparatus for attaching the lid and body portions of a metallic container includes a base to support the body, a support assembly to support a flange of the body, and a sonitrode for contacting a flange of the lid, wherein the flanges of the lid and body are held together between the support assembly and the sonitrode. A motor reciprocally rotates the sonitrode relative to the support assembly, thereby moving the flanges relative one another to generate frictional heat and create a friction weld therebetween.

Abstract: Mixtures or adducts of N-heterocyclic carbenes with metal amides or metal alkoxides are effective catalysts for the polymerization of cyclic amides. The catalysts are stable at polymerization temperatures, and the polymerization is rapid, resulting in high monomer conversion, high molecular weight, and a mechanically sound material.

Abstract: A sonotrode specially adapted for defoaming liquids during container filing operations, has an upper body portion having a first diameter and having an upper face adapted to be mounted to a driving transducer, a middle body portion having a second diameter larger than the first diameter situated below the upper body portion, a generally conical portion situated between the upper body portion the middle body portion, and a transition portion situated between the middle body portion and a lower face adapted to be directed toward a liquid upper surface within a container, the lower face being generally rectangular.

Abstract: Compositions of thermoplastic polyesters and sepiolite-type clay in which the clay is dispersed in the polyester as often fibrous particles whose smallest dimension is less than 100 nm are made by polymerizing the polyester precursors in the presence of the clay. The compositions have good physical properties and can be melt molded into various articles. Many of these articles may be coated (painted) and are especially useful for appearance parts such as visible exterior automotive body parts.

Abstract: The present invention is a method for reducing the permeability of gases through polyester containers and films by incorporating into the polymer from which the container or film is formed an effective amount of exfoliated sepiolite-type clay.

Abstract: A method for dispersing sepiolite-type clay particles in a polyester matrix by melt-compounding a mixture of: sepiolite-type clay, at least one linear polyester oligomer, and at least one polyester polymer to produce a nanocomposite composition; and, optionally, subjecting said nanocomposite composition to solid state polymerization to increase polyester molecular weight. Further described is a method for preparing a polyester nanocomposite composition from a masterbatch, comprising melt-compounding a mixture of: sepiolite-type clay, at least one polyester oligomer, and at least one polyester polymer to produce a nanocomposite composition containing a greater concentration of sepiolite-type clay than is desired in the final resin composition; optionally, subjecting said nanocomposite composition to solid state polymerization to increase the polyester molecular weight; and further melt compounding said nanocomposite composition with polyester polymer and, optionally, additional ingredients.

Abstract: An apparatus includes a container defining an internal region configured to contain multiple medicament delivery devices, such as, for example, pen injectors, auto-injectors, inhalers or the like. The container includes an electronic circuit system configured to output a first electronic output associated with a first medicament delivery device contained within the internal region when the first medicament delivery device is removed from the internal region of the container. The electronic circuit system is further configured to output a second electronic output associated with a second medicament delivery device contained within the internal region when the second medicament delivery device is removed from the internal region of the container. The second electronic output is different than the first electronic output. At least one of the first electronic output or the second electronic output is associated with a use instruction.

Abstract: A system for providing a dynamic multi-mode service acquisition capability to a subscriber station is provided. The subscriber station is capable of operating in two or more modes of operation. A time to scan condition is indicated while the subscriber station is operating in a current mode of operation having active and inactive states. Responsive thereto, the system stores state information for the current mode of operation, and attempts at least a partial acquisition of communications services in accordance with another mode of operation. The at least partial acquisition attempt is scheduled to be initiated while the subscriber station is operating in the inactive state in the current mode of operation, and completed before the subscriber station transitions back to the active state in the current mode of operation. If the acquisition attempt is successful, the subscriber station transitions to the new mode of operation, maintaining appropriate registration.

Abstract: The collaboration framework is a facility for entities, such as service providers and tools, to work jointly in the intellectual endeavor of finding solutions to engineering problems. The collaboration framework incorporates protocols and means for expansion and interfacing with Web services as well as discoverable, reusable work flows for solving engineering problems. Other problems for which the collaboration framework can be used include military operations, emergency responses, such as responses to an earthquake, fire, terrorism, or other disaster.

Abstract: A device for supporting a standard size keyboard tray within an electronics rack or cabinet. The keyboard supporting device includes a slideable shelf and a keyboard tray that is rotatably mounted thereto. The keyboard tray is rotatable between a storage position in which the keyboard tray is substantially perpendicular to the slideable shelf and a use position in which the keyboard tray is substantially parallel to the slideable shelf. A biasing device is included for biasing the keyboard tray toward either the storage position or the use position when the keyboard tray is disposed between the use position and the storage position.
