Abstract: A plasma treatment system for treating a workpiece with a downstream-type plasma. The processing chamber of the plasma treatment system includes a chamber lid having a plasma cavity disposed generally between a powered electrode and a grounded plate, a processing space separated from the plasma cavity by the grounded plate, and a substrate support in the processing space for holding the workpiece. A direct plasma is generated in the plasma cavity. The grounded plate is adapted with openings that remove electrons and ions from the plasma admitted from the plasma cavity into the processing space to provide a downstream-type plasma of free radicals. The openings may also eliminate line-of-sight paths for light between the plasma cavity and processing space. In another aspect, the volume of the processing chamber may be adjusted by removing or inserting at least one removable sidewall section from the chamber lid.

Abstract: An injection vessel for injecting liquid amendment into contaminated subsurface sediment in ecologically sensitive areas such as shallow water salt marshes, tidal flats, or fresh water wetlands is disclosed. The injection vessel described herein includes a shallow-draft floating platform that has an injection system mounted thereon. The injection system includes an injection grid containing a plurality of injection syringes that receive liquid amendment from a metering pump. The injection grid is lowered such that the output of the injection syringes is within the contaminated sediment. The metering pump provides the liquid amendment to the injection syringes and a fluid path is established that injects the liquid amendment into the contaminated sediment. A propulsion system mounted on the floating platform provides for locomotive and maneuvering power.

Abstract: The present invention relates to an integrally bladed rotor for use in a gas turbine engine. The integrally bladed rotor comprises a plurality of pairs of airfoil blades. Each pair of blades has a spar which extends from a first tip of a first one of the airfoil blades in the pair to a second tip of a second one of the airfoil blades in the pair. The rotor further comprises an outer shroud integrally joined to the first and second tips in each pair of airfoil blades and an inner diameter hub.

Abstract: Combining ceiling framework and structural members of skylight plenum enclosures in daylighting applications wherein the light shaft enclosures are designed to be suspended over a ceiling framework. Only the light reflective fabric of the light shaft connects to the ceiling. The light shaft thus floats above the ceiling framework and thereby has minimal impact on it. The light shaft is supported by the framework of the roof aperture by the rigid corner material that forms the light shaft.

Abstract: A method of controlling access to a data server, in which a web server receives a request from a client for a web page, the web page being configured to receive data from the data server for display by the client. In response to the request, a program associated with the web server generates a password signed with a private key to provide the client with access to the data server. The corresponding public key has previously been sent to the data server. The password is returned to the client and program code in the web page directs the client to connect to the data server. The data server receives the password and attempts to validate it using the public key received from the web server. Data is sent to the client in the event that the password is successfully validated.

Abstract: Combining of ceiling frameworks, and structural members of skylight plenum enclosures in daylighting applications. When daylighting enclosures are designed without enclosure assemblies being directly connected to suspended ceiling types framework, but only extend and connect to the ceiling via the fabric portion of structure. Allowing daylighting enclosures to “float” above the ceiling framework and have minimal impact upon it when connected.

Abstract: First and second alternating signals at a central office are applied to a telephone subscriber's lines. The level of the second signal current is used to control the level of the first signal. The nonlinear impedance vs. voltage characteristic of the subscriber's telephone in an off-hook state causes harmonics of the first signal to be generated. Harmonics so generated are detected at the central office to indicate the presence of a receiver-off-hook telephone.
