Abstract: Polyoxymethylene polymer compositions and molded articles made from the composition are disclosed that are fuel resistant, particularly diesel fuel resistant, and resistant to highly acidic solutions. The polymer composition contains a polyoxymethylene polymer combined with a combination of stabilizers, such as a combination of at least three different stabilizers. In addition, the polymer composition contains an acid neutralizing agent and optionally a plasticizer.

Abstract: An auxetic material comprises an outer component of a relatively compliant material, and an inner component of a relatively stiff material, wherein the inner component is located within a cavity provided within the outer component, the cavity being of non-linear form in the longitudinal direction of the material when the material is at rest.

Abstract: A fibrous assembly includes two components. The first component provides a visual indication of when a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended. The first and second components are movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the pre-determined tensile load is applied to the assembly or when the fibres have been over-extended. The first component comprises auxetic yarn.

Abstract: The present invention relates to a method for enhancement of the minimal shear molding process utilizing pellets and/or micropellets produced through controlled extrusional and pelletization processes in combination with nonpowder melt flow rheology that incorporates reduced molding temperature and/or reduced cure time, reduced rotation axis ratios and/or reduced rotation rates. Molding can be uniaxial, biaxial, or multiaxial rotational or oscillatory or both. The molded items produced can be single or multiple layers and can be produced in one or more molding sequences using similar or different chemical compositions.

Abstract: A self-cleaning centrifugal dryer system and method for removing surface moisture allow complete removal of plastic pellets, flakes and particles from the dryer and water-conveying or water processing system during or after each drying cycle. By eliminating plastic particulate retention in the dryer and throughout the water conveyance and processing systems whereby contamination of different type materials dried during a subsequent drying cycle is avoided. Air and water alone or in combination under pressure are discharged toward various accumulation or occlusion (“hang-up”) points in the dryer and throughout the water-conveying or processing system to remove retained plastic pellets, flakes and particles.

Abstract: Described herein is a system for the management of security domains. The system comprises a managing security domain (10), a firewall (70) and two or more managed security domains (80, 100). The managing security domain (10) includes a plurality of nodes (12, 14, 16) of which one is a management node (16) for managing the domain (10). Each managed security domain (80, 100) comprises a plurality of nodes (82, 84, 102, 104). The management node (16) operates in conjunction with the firewall (70) to manage the managed domains, the firewall (70) allowing the transfer of information across domains having different security levels.

Abstract: A high frequency transducer having a dome diaphragm with a configuration of a bisected ellipse to overcome the distortion and breaking point of prior art even domes at frequencies above 30 kHz. The dome diaphragm having an annular skirt extending therefrom in an integral fashion and connecting to a disc shaped plate of the transducer. A voice coil of cylindrical section being directly connected to the skirt at a region of close proximity to said dome. The dome being constructed of a rigid material such as a metal, an alloy, a metalloid such as, but not limited to, titanium, aluminum, and boron, or a combination thereof. The dome being constructed in accordance with a general formula for an ellipse (x2/a2)+(y2/b2)=1, and a>b. Wherein a is half of the distance of major axis and b is half of the distance of a minor axis.

Abstract: A replaceable housing for a mobile communication device. The mobile communication device can include an inner module, a cap outer housing and a base outer housing. The inner module can include a first inner module housing, a second inner module housing, and a tongue including a portion of the first inner module housing and a portion of the second inner module housing. The cap outer housing can include a slot along an inner length of the cap outer housing. The base outer housing can also include a slot along an inner length of the base outer housing. The tongue can include a portion of the first inner module housing and a portion of the second inner module housing.

Abstract: Disclosed is an otherwise conventional wood molding that has a keyhole slot milled along its length on the mounting side thereof. Special mounting plates are attached to the wall via nails or other fasteners and include a specially designed key protrusion that mate with the keyhole slot. Inserting the key into the keyhole slot, the molding can be attached to and removed from the wall quickly, easily and repetitively without damaging either the molding or the wall.
