Abstract: An exhaust gas cooler for reducing the temperature of exhaust gases from internal combustion engines, comprising an external tube extending between two tube plates or end walls and defining a coolant chamber, coolant inlet and outlet means communicating with the coolant chamber, and a plurality of internal tubes extending between the end walls and arranged to carry the exhaust gas through the coolant chamber. The external tube has a cross-sectional shape which has a height (H) in the major axis which is greater than its width (W) in the minor axis perpendicular to the major axis, preferably oval, or comprising two semi-circles connected by common straight line tangents parallel to the major axis. Such a cross-sectional shape means that the exterior tube has a planar face which simplifies the fitting of mounting brackets and placement with an engine compartment.

Abstract: The present invention provides for generating inputs that can be provided to a message classification module to facilitate more reliable classification of electronic messages, such as, for example, as unwanted and/or unsolicited. In one embodiment, a sending messaging server provides an appropriate response to address verification data thereby indicating a reduced likelihood of the sending messaging server using a forged network address. In another embodiment, it is determined if a messaging server is authorized to send electronic messages for a domain. In yet another embodiment, electronic message transmission policies adhered to by a domain are identified. In yet a further embodiment, a sending computer system expends computational resources to solve a computational puzzle and includes an answer document in an electronic message. A receiving computer system receives the electronic message and verifies the answer document.

Abstract: The present invention is directed to a method and system for disaggregating and connecting ANV components, and communicating A/V content stream information. An A/V stream from a source device is packaged for transmission over an IP network to one or more output devices. A brick device enables the integration of legacy A/V systems into the network supported A/V system. The brick device operates to provide analog signal and IP protocol conversion, along with the synchronization of received A/V stream data packets. The rendering and play of the A/V stream content on multiple output devices is synchronized to overcome distortions and other network idiosyncrasy and to facilitate a pleasant user experience.

Abstract: A business relationship is effectuated between a first party and a second party and is governed by an agreement between the first party and the second party. The first party creates a token that authorizes a delegate to request a transaction according to the agreement on behalf of the first party, specifies in the token at least one constraint on a transaction requested by the delegate on behalf of the first party, and provides the token to the delegate. The delegate sends to the second party the token and a transaction document requesting a transaction according to the agreement. The second party applies each constraint in the token against the transaction document to determine whether the transaction document satisfies each constraint. If so, the transaction document is accepted for fulfillment.

Abstract: A method and system are provided such that a universal license may be used for authentication and authorization purposes and may include one or more cryptographic keys as well as assertions and related indications of authenticity. In an aspect of the invention, a license may be presented that includes access information, such that authentication and authorization decisions may be made based only on the access information. In other aspects of the invention, rights may be delegated and a trusted party may assert that another party can be trusted.

Abstract: 11-Aminopropylidene-Pyrrolo[2,1-b] [3]benzazepines are disclosed to have pharmaceutical utility as skeletal muscle relaxants and tranquilizers. They are prepared by a Grignard reaction on pyrrolo[2,1-b] [3]benzazapin-11-ones followed by dehydration, or by a Wittig reaction on the same ketones.
