Title: Method and apparatus for a flexible access rate common-memory packet switch
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-11-17
Granted: 2004-05-18
Abstract: A method of controlling asymmetrical port access in a common-memory (CM) multi-port data packet switch and a high-capacity flexible access rate CM data packet switch are described. The method involves providing a common-memory- access control table which defines a unique contiguous band of CM access time slots allocated to each port of the packet switch. Each access time slot is identified by a time slot identifier. Time slot identifiers are generated at a regular interval. The time slot identifiers are generated so that CM access time for each port is substantially equally spaced to minimize delay fitter. The packet switch may have an equal number of input and output ports, or more output ports than input ports. In the high-capacity CM packet switch, several CM switch modules are interlinked by middle buffers in a folded configuration to provide a packet switch having Terabit output capacity. The advantage is a packet switch architecture which supports flexible access rates to eliminate idle switch capacity, the CM access time slots being substantially equally spaced apart to reduce packet transfer delay fitter.

Abstract: A well configuration is provided comprising an injection well completed relatively high in an oil reservoir and a production well completed relatively low in the reservoir. The production well has a horizontal leg oriented generally perpendicularly to a generally linear and laterally extending, upright combustion front propagated from the injection well. The leg is positioned in the path of the advancing front. Oil upgrading catalyst has been emplaced along the horizontal leg. The production well is maintained open, thereby providing a low pressure sink which induces the front to advance along the leg. The hot combustion gases react with the commingled oil over the catalyst to provide in situ upgrading.

Abstract: An adapter is designed to interconnect the two glad hands that extend from the adjacently disposed ends of a pair of rail vehicles in a train. The housing of the adapter includes first and second connector bodies and an intermediate portion situated between the two connector bodies. The adapter housing encloses a flow chamber that runs from the first connector body through the intermediate portion to the second connector body. The intermediate portion defines a vertically disposed access port in communication with the flow chamber of the adapter housing.      The connector bodies are formed on opposite, vertically oriented sides of the adapter housing. Each connector body features a mating surface from which a flow port in communication with the flow chamber emerges. Each connector body also includes a mechanism that allows the connector body to mechanically couple to one of the glad hands. When so coupled, the mating surface of the connector body is aligned with the mating surface of its corresponding glad hand with a sealing member of the glad hand held in compression therebetween. By coupling the glad hands to connector bodies of the adapter, a leak proof passage is provided from one glad hand through the flow chamber and the flow ports of the adapter housing to the other glad hand. It is directly to the access port or indirectly via a fitting that an external device can connect for the purpose of affecting the pressure contained by the brake pipe of the train.

Abstract: A dredging apparatus (24) works on the seabed (14). It is especially intende d for the removal of cuttings gathered around a bore hole mouth at seabed (14), the removal being carried out by means of an ejector (30, 40) having coupled thereto a suction hose (32) and a conveyor pipe (34), respectively, for moving the cuttings to another place on the seabed (14). The dredging apparatus (24) comprises a drive motor (22), a pumping device (38) and an ejector (30, 40), the drive motor (22) being adapted to drive the pumping device (38) which, in its turn, is adapted to deliver a forced flow of water to the ejector (30, 40) in order to establish and maintain the ejecting effect. In order to avoid the pumping-down of enormous amounts of water to large depths by means of a motor-driven pumping device in a surface position, which is particularly energy, weight and space demanding on board of the rig, the ejector (30, 40), pumping device (38) and drive motor (22) are assembled to form a unit. A cable (20) delivers energy to the motor (22) from the surface.

Filed: 1998-03-10
Granted: 2005-05-24
Abstract: A service creation environment (SCE) (10) generates generic service creation information defining a certain service. The generic service creation information is then processed by a service execution agent (14) for mapping (102) onto service creation information that is specific to the service logic execution environment (SLEE) (12) of a service control point (SCP) upon which the service is to be executed and provided. This SLEE specific service creation information is then down-loaded (104) to the service logic execution environment, and converted in a conventional manner to service execution related information. The generic service creation information comprises only a certain limited number of primitives (instructions or commands) operating on a certain limited number of service independent building blocks (SIBs). The mapping operation (102) is made from these limited primitives and service independent building blocks to SLEE specific primitives and service independent building blocks, or SLEE specific general programming language commands, or SLEE specific specification description language (SDL) commands

Granted: 2008-12-30
Abstract: The present invention provides a method and apparatus for non--destructive, in situ measuring thicknesses of layers on substrates. The method and device uses a probe including a radioactive source in a source holder and a photodetector mounted behind the source for detection of backscattered photons. In one aspect the method is used to measure the thickness of paint deposited onto metal substrates. The source holder and photodetector array forms a cylindrically symmetric probe for producing an axially symmetric beam of primary photons. A source containing radioactive 109Cd producing high energy photons of energy 22 and 25 keV is spaced from the painted surface so the photons impinge on the painted substrate. The intensity of photons backscattered by Compton scattering in the paint layer is proportional to the mass density of the paint to give a direct measurement of the paint thickness.    The photons penetrating through to the substrate are absorbed within the substrate. The device also provides a method for calculating the distance from the source holder to the substrate using backscattering of gamma rays.
