Title: Network resource communication system
Inventor: SPICER STEVEN
IPC: H04L12/911
Filed: 2001-03-01
Granted: 2010-08-17
Abstract: A network resource communication system facilitates communication over a network between network terminals and network resources, and comprises a network resource driver, a driver administrator, and a data transmitter. The network resource driver facilitates communication of source data between the network terminals and one of the network resources, and includes a driver input for receiving the source data and a driver output for providing a translation of the source data in accordance with the network resource. The driver administrator is in communication with a resource registry, and includes resource records associated with the network resources. The resource records define at least a resource type for each network resource, and the driver administrator is configured to configure the network resource driver in accordance with the resource record associated with the network resource. The data transmitter is in communication with the driver output for transmitting the translated data to the network resource.

Granted: 2009-03-17
Abstract: A method includes receiving at least two space-time coded signals from an antenna system associated with a first station, determining complex channel state information based on the received space-time coded signals, and sending the complex channel state information to the first station. In an alternative embodiment, a method includes transmitting at least two space-time coded signals in respective beams of a multi-beam antenna array, measuring a channel impulse response for each space-time coded signal at a second station, and sending an indicia of a selected set of least attenuated signals from the second station to the first station. The multi-beam antenna array is associated with a first station. The beams transmit a signature code embedded in each respective space-time coded signal, and the signature codes are orthogonal so that the second station can separate and measure the channel impulse response corresponding to each space-time coded signal. The space-time coded signals include the selected set of least attenuated signals and a remaining set of most attenuated signals. In an alternative embodiment, a method includes selecting at least two beams of plural beams formed by a multi-beam antenna array associated with a first station for transmission of a corresponding at least two space-time coded signals produced by a space-time encoder, determining a time delay associated with each of the at least two space-time coded signals as received in each respective beam, and setting into a variable delay line the time delay corresponding to each beam, each variable delay line being coupled between the multi-beam antenna array the space-time encoder.

Abstract: The present invention is directed to rigid disposable food containers provided with a relatively steep sidewall with a generally linear profile and an outwardly flared arcuate flange portion. The containers are further characterized by a flange outer vertical drop wherein the ratio of the length of the vertical drop to the characteristic diameter of the container is greater than about 0.01. By virtue of unique geometry, the containers of the invention exhibit improved rigidity and/or rim stiffness yet have favorable runnability in pressware manufacturing systems characteristic of plates of lower strength.

Abstract: A permeable industrial fabric is assembled from a plurality of separate tiles into at least two plies, and in which the two plies are held together by jointing structures made integrally with the tiles. In these fabrics, within each tile the jointing structures are incorporated at primary selected locations according a symmetrical pattern, and the apertures in the tiles which provide the required fabric permeability are incorporated at secondary and tertiary selected locations according two more patterns, at least one of which is asymmetrical. This combination of symmetry and asymmetry allows for some control over the permeability of the assembled fabric.

Abstract: A process for making functional or decorative flakes or platelets comprises applying a multi-layer sandwich of vapor deposited metal (46, 48, 50) and release coats (44) in alternating layers to a rotating chilled drum (36) or suitable carrier medium contained in a vapor deposition chamber (30). The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent soluble thermoplastic polymeric materials applied by vapor deposition sources contained in the vapor deposition chamber. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable organic solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free. The solvent and dissolved release material are the removed by centrifuging to produce a cake of concentrated flakes which can be air milled and let down in a preferred vehicle and further sized and homogenized for final use in inks, paints or coatings.

Title: System for preventing incorrect loading of printer paper trays
Inventor: LEVETO MARK L
IPC: B41J13/00
Filed: 2004-06-18
Granted: 2008-09-23
Abstract: A printer paper tray improper loading protection system which is automatically moved by the repositioning of a conventional repositionable stack edge guide to restrict improper loading of sheets into the area of the tray which is outside of the proper sheet stacking area for sheet feeding, even though that restricted area varies depending on the selected size of the sheets being properly loaded within the proper sheet stacking area. A customer warning and partial obstruction of the non-feeding restricted area of the tray eliminates confusion as to where the operator should load paper into the tray whenever the tray is accessed, no matter where the tray stack edge guides are positioned for different paper sizes. An accordion-folded, reeled, or other expandable and contractible member operatively connects between the repositionable stack edge guide and the opposite end of the tray, extending above the tray stacking surface therebetween.

Title: Process and device for production of lng by removal of freezable solids
Inventor: AMIN ROBERT
IPC: F25J3/00
Filed: 2003-01-17
Granted: 2008-08-19
Abstract: Novel processes and devices for the removal of freezable species such as carbon dioxide, water and heavy hydrocarbons from a natural gas feed stream during liquefaction to produce LNG are disclosed. The freezable species are able to be removed as a solid, avoiding the costly step of pre-treatment to remove the freezable species from the natural gas feed stream prior to the liquefaction stage. The freezable species may be removed on a continuous basis being separated as solids following liquefaction of the natural gas feed stream with subsequent separation of the solids. The solid freezable species may then be liquefied on a continuous basis if required with natural gas recycled to the process. Continuous removal of the freezable species from the natural gas feed stream is achievable by maintaining cooling and separation apparatus at the same working pressure. Advantageously, at least part of the cooling vessel is constructed from a material having a low thermal conductivity which discourages formation of the solids of the freezable species on the walls of the cooling vessel.
