Abstract:
Phthalocyanine pigments having 0-4 chlorine atoms have a narrow particle-size range with 90% of particles between about 0.01-0.10 μm, the average particle size of no more than about 0.5 μm, a D99 of no more than about 0.3 μm, and a polydispersity of about 2.0 or less. Pigment compositions contain the phthalocyanine pigment and water-based dispersing resin. The pigments and the compositions are compatible with waterborne coating systems, exhibit an excellent metallic down travel, and are especially useful for the automotive painting applications.
Abstract:
A cryopump provides for high pumping speed of Type III gases. An open configuration of a frontal array provides high conductance of gases into a radiation shield which is shaped to focus gases toward a second stage array. The second stage array has an open configuration of baffles coated with adsorbent. Substantially all of the adsorbent has a direct line of sight to the radiation shield or to the opening in the radiation shield, and substantially all of the baffles are coated with adsorbent. In one form, the second stage cryopump array comprises an array of discs fanned to define a generally ball shaped envelope.
Abstract:
An electronic module includes a substrate, at least one surface mounted integrated circuit (IC) component and an underfill material. The substrate includes a plurality of electrically conductive traces, formed on at least one surface of the substrate, and the component is electrically coupled to at least one of the conductive traces. The underfill material is positioned between the component and the substrate and provides at least one pedestal that supports the component during encapsulation. The underfill material, when cured, maintains the integrity of the electrical connections between the component and the conductive traces.
Abstract:
A sealing arrangement for a stator shroud segment is provided that includes a resilient seal to reduce air leakage and improve turbine engine efficiency. The stator shroud segment includes an outer shroud having a leading edge groove and a trailing edge groove, and a plurality of inner shrouds each having a leading edge hook and a trailing edge hook. The leading and trailing hooks of each of the inner shrouds are respectively engaged with the leading and trailing edge grooves of the outer shroud so as to connect the inner shrouds to the outer shroud. A resilient shaped seal is located on a leading edge hook of the inner shroud so as to be between the leading hook and a retaining ring that contributes to holding the inner shroud in place.
Abstract:
Methods and systems for usage-based product definition are disclosed. In one embodiment, a method includes instancing one or more usage-based product definition inputs, and assessing at least one of an applicability expression, an engineering requirement, and a manufacturing availability expression. The method further includes generating the product definition based on at least some of the usage-based product definition inputs, applicability expressions, engineering requirements, and manufacturing availabilities. In alternate embodiments, the instancing may include transforming a coordinate system of a component from a component-centered coordinate system to a product-centered coordinate system.
Abstract:
A seal assembly adapted for use in conjunction with a trocar assembly includes a seal body permitting the selective insertion and removal of instruments. The seal body includes a plurality of overlapping seal segments, each seal segment including a peripheral edge with a central seal member extending therefrom. The central seal member includes a free edge remote from the peripheral edge. A reinforcement pad is located on at least one of the seal segments between the peripheral edge and the free edge of the central seal member.
Abstract:
Third stage turbine buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X and Y values are in inches and the Z values are non-dimensional values from 0 to 1 convertible to Z distances in inches by multiplying the Z values by the height of the airfoil in inches. The X and Y values are distances which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape. The X, Y and Z distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of ±0.060 inches in directions normal to the surface of the airfoil.
Abstract:
The present invention provides a series of new and improved compounds/materials as vehicles to delivery degradative enzymes to remove/remedy environmental pollutants. The inventive material comprises a series of amide-functionalized ordered mesoporous carbon (AFOMC), which utilizes chemical conjugation techniques for the tethering of enzymes to the surface of the synthesized AFOMC. The delivery mechanism may be utilized to express a wide variety of toxin-degrading enzymes for removal/remediation of organic pollutants.
Abstract:
The present disclosure features methods and systems for enforcing parametric constraints in a direct modeling interface in computer-aided design (CAD). A parametric geometry engine of a CAD application may compare an attempted edit to a feature in a direct modeling user interface of the CAD application to an existing constraint created in a parametric modeling user interface, and, in one embodiment, prevent the user from completing the edit. In other embodiments, the parametric geometry engine may present a dialog box to the user and allow them to reject the edit, override or delete the constraint, modify the constraint, or take other actions as appropriate. In still other embodiments, the parametric geometry engine may allow one user to edit the feature, but not another user. Thus, parametric constraints and permissions-based ownership of entities may be enforced in a direct modeling user interface.
