摘要:
An aircraft fueling system (890) includes an underground fuel supply (904). A fuel pump (906) is coupled to the underground fuel supply 904 and is used to supply fuel to an aircraft (902). A fuel probe (908) is coupled to the fuel pump (906) and is extendible to an aircraft fueling port (926). A fuel probe connection sensor (938) generates a connection signal. A controller (924) is coupled to the fuel pump (906) and the fuel probe connection sensor (938) and adjusts the supply of the fuel (904) to the aircraft (902) in response to the connection signal.

A servicing bridge (14) for an airport (13) includes multiple servicing levels (82, 102). A bridge (81) includes one or more of the servicing levels (82, 102) and extends from a terminal of the airport (13). A ground support service sub-system is coupled to the servicing levels (82, 102) and is configured to mate with a service opening (26) of the aircraft (12). The ground support service sub-system provides services to the aircraft (12) through the service opening (26) and on the servicing levels (82, 102).
摘要:
A method of converting oxygenate-containing feedstock to light olefins comprises charging a reactor with catalyst, feeding the feedstock into the reactor, contacting the feedstock with the catalyst and converting the feedstock to olefins while depositing byproducts on catalyst resulting in spent catalyst, regenerating the spent catalyst by combustion gases, and stripping the regenerated catalyst of gases entrained in the regenerating step. The stripping step is accomplished using nitrogen gas to strip the entrained gases from the regenerate catalyst. In one embodiment, regenerated catalyst is passed through a regenerated catalyst stripper before it is returned to the reactor.
摘要:
Electromagnetic-energy absorbing materials are combined with thermally conductive materials, such as those used for thermal management in association with electronic equipment, thereby suppressing the transmission of electromagnetic interference (EMI) therethrough. Disclosed are materials and processes for combining EMI-absorbing materials with thermally conductive materials thereby improving EMI shielding effectiveness in an economically efficient manner. In one embodiment, a thermally conductive EMI absorber is prepared by combining an EMI-absorbing material (for example, ferrite particles) with a thermally conducting material (for example, ceramic particles), each suspended within an elastomeric matrix (for example, silicone). In application, a layer of thermally conductive EMI-absorbing material is applied between an electronic device or component, and a heat sink
摘要:
The present invention comprises a process and apparatus for producing olefins from oxygenates in a reactor. This process comprises these oxygenates with a catalyst to produce a gaseous mixture comprising light olefins and by-products, sending the mixture to a single stage cyclone within said reactor to separate said catalyst from said gaseous mixture and then sending said the to a second stage cyclone. The second stage cyclone is located outside of said reactor and it functions to remove the catalyst from the mixture. Then the catalyst can be returned to the reactor after having been treated in a regeneration zone to remove carbonaceous deposits from the catalyst.

A dual drive system for a hydraulic pump and an air boost compressor is provided. Reversible power is transmitted to a shaft connected to clockwise and counterclockwise over-running clutches connected to different vehicle or equipment subsystems. Reversing the drive allows power to be alternately transmitted to one or the other of the subsystems. The invention includes utilizing the dual drive for hydraulic and air conditioning systems for an aircraft, with the provision of an additional drive motor providing constant power to one or more of the subsystems.

A first transmitting device is used to transmit a first signal on a first carrier frequency to a relay device. The relay device receives the signal by demodulating the first carrier frequency. Subsequently, the relay device retransmits the signal by modulating a second and/or a third carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the second and/or third carrier frequencies. Further, a second transmitting device transmits a second signal on a fourth carrier frequency and the relay device retransmits the signal by modulating a fifth and/or a sixth carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the fifth and/or sixth carrier frequencies. The transmitting and/or receiving devices are preferably voice terminals, such as a wireless telephones or data terminals, such as portable computers. The transmitting and/or receiving devices are optionally coupled to a communications network, such as a public switched telephone network or the Internet. The relay device is preferably a multiple beam satellite and/or a ground station covering several distinct geographical regions.

A tracking system for tracking a plurality of items or boxes of items defines a plurality of levels that may be physically and logically organized in a hierarchy. Each level of the hierarchy only communicates with the next hierarchically lower level (if it exists) and/or a next hierarchically higher level (if it exists). The lowest hierarchical level includes a wireless tag coupled to each of the plurality of items. Each of the wireless tags may be configured to provide a unique identifier when queried. Remaining hierarchical levels may each include one or more uniquely identified computing devices that are configured to query the wireless tags or computing devices of the next hierarchically lower level, to store information including the unique identifier and any other information provided by the queried next hierarchically lower level and to provide the stored information to the computing device(s) of the next hierarchically higher level (if it exists). A sealed box or document may form a part of the hierarchy and may include a conductive mesh coupled to a wireless tag, repeater or computing device that is configured to report on the state of the conductive mesh.

A computer-implemented draft authentication method for use in e-commerce includes the steps of establishing partner relationships between a financial institution and a plurality of World Wide Web (Web) vendors and storing, for each of a plurality of Web customers, at least one piece of unique identifying information linked to the Web customer's financial information. Web customers executing drafts or causing drafts to be executed by the Web vendors and presented to the financial institution are authenticated by immediately encrypting at least a portion of an identification data set provided by the Web customer over the network and by successfully matching the immediately encrypted identification data set with the stored piece(s) of encrypted identifying information. The Web customer's financial information is then retrieved only by the financial institution and constraints are established based on the retrieved information. The financial institution then honors drafts presented by the Web vendors with whom the drawee has a partner relationship only when the Web customer is successfully authenticated and the constraints are satisfied. Only the identification information (such as biometric data and/or ID and password pairs) of each of the Web customers is securely replicated from the financial institution to each of the Web vendors. LDAP-compatible Directory software may be utilized as the means of storing, processing and replicating the Web customer's identification information to each of the Web vendors. The financial institution warrants the security of the system and controls the replication and content of the Directories at each of the Web vendor sites.
