  • Patent number: 9473565
    Abstract: Techniques are disclosed to transmit arbitrarily large data units for transaction processing in a networked environment. A request is received to store a data unit of a size exceeding an allocated memory address space of a transaction gateway component of the networked environment. A predefined store function, provided by a repository interface component, is invoked to store the data unit to a data repository component of the networked environment and without segmenting the data unit. A repository handle of the stored data unit is identified. A predefined load function, provided by the repository interface component, is invoked to load a portion of the stored data unit, based on the identified repository handle, where the portion is smaller than the stored data unit.

  • Patent number: 7968206
    Abstract: This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a primer surfacer, a basecoat, and a clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step, wherein the primer surfacer comprises: a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about: (a) about 30 to 80% by weight, based on the weight of the binder, of a hydroxyl functional polyester resin; (b) about 10 to 30% by weight, based on the weight of the binder, of a crosslinking agent selected from the group consisting of a melamine resin, a blocked polyisocyanate resin, or a mixture thereof; (c) about 10 to 40% by weight, based on the weight of the binder, of a dispersed graft polymer comprising a non-crosslinked core of acrylic polymer which is substantially non-soluble in non-polar organic solvent and, grafted to the core, one end of an acrylic sta

  • Patent number: 7818566
    Abstract: An apparatus, system, and method are provided for sharing a cached security profile in a database environment. The apparatus, system, and method include a cache module for caching a security profile accessible to primary tasks and secondary tasks. An identification module is provided that distinguishes between primary tasks authorized to refresh the security profile and secondary tasks. A refresh module cooperates with the cache module and identification module to selectively refresh the security profile in response to a refresh request and expiration of the security profile such that an old version of the security profile is retained for use by secondary tasks until an execution window closes.

  • Patent number: 7804147
    Abstract: A method for fabricating a light emitting diode (LED) package comprising providing an LED chip and covering at least part of the LED chip with a liquid encapsulant having a radius of curvature. An optical element is provided having a bottom surface with at least a portion having a radius of curvature larger than the liquid encapsulant. The larger radius of curvature portion of the optical element is brought into contact with the liquid encapsulant. The optical element is then moved closer to the LED chip, growing the contact area between said optical element and said liquid encapsulant. The liquid encapsulant is then cured. A light emitting diode comprising a substrate with an LED chip mounted to it. A meniscus ring is on the substrate around the LED chip with the meniscus ring having a meniscus holding feature.

  • Patent number: 7740912
    Abstract: This invention relates to a method for forming a multi-layer coating on a vehicle body, comprised of applying primer coating, base coating, and clear coat layers in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer layer comprises a film-forming binder (a) a caprolactone-modified linear acrylic polymer; and (b) an aminoplast resin crosslinking agent, wherein the composition is essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting multi-layered coating film has excellent aesthetic appearance, strike-in resistance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.

  • Publication number: 20080274240
    Abstract: A method and apparatus for controlling efficacy of a food processing system. The method includes, responsive to receiving set points from an automatic expert system, operating an adaptive controller to perform steps including comparing the set points from the automatic expert system to process variables for the food processing system. The steps also include generating an error signal indicating a difference between the compared process variables and the set points and adjusting control settings for the food processing system using the error signal and one or more control parameters. The adaptive controller is configured to automatically modify the control parameters in response to a detected change in at least one of the set points and the process variables.

  • Publication number: 20080124448
    Abstract: Processes for maintaining the stability and quality of frozen desserts during storage and transportation, including an improvement. This improvement process involves flushing the ambient air in the storage compartment and flushing this storage compartment, with either a low molecular weight gas, a high molecular weight gas, or a combination of both. The gas mixture in the compartment would allow the cells within the frozen dessert to remain at approximately a constant volume during elevation changes, thereby reducing or eliminating shrinkage and transportation settling.

  • Publication number: 20080063768
    Abstract: Systems and methods improve the useful life of fry oil by inhibiting or eliminating factors that degrade the oil. A flow of gas in contact with the oil provides efficient cooling of the oil that was heated but is for a temporary period of time not needed to be kept hot. Further, utilizing inert gas for the cooling provides protection of the oil from oxidation. For example, chilled or liquid nitrogen gas introduced into a head space above an oil surface and/or into the oil both cools the oil and protects the oil from oxidation.
