Abstract: A deformation compensation system for use with a large phased-array antenna system to electronically compensate for surface deformations occurring on the phased-array antenna which would otherwise compromise antenna performance. In one embodiment, a plurality of strain gauges are disposed on or integrally formed in structure forming the phased-array antenna. The strain gauges are placed at those locations on the antenna structure, where, through prior structural modeling and testing, it has been determined that high strains associated with the expected deformation of the phased-array antenna are expected to occur to a significant degree. The strain gauges output signals to a data acquisition system which uses a strain-to-displacement algorithm to produce displacements corresponding to the estimated, deformed shape of the phased-array antenna.

Abstract: The invention provides the combination of a seat frame and a cover, having a seam, covering the seat frame. An air bag unit, having an air bag, is disposed inside the cover and is supported by the frame. An intensifier sleeve, having a pair of sheets, sandwiches the air bag therebetween with the sheets being connected to the seam of the cover and supported by the seat frame. A fastener is included and has outboard and inboard portions with the portions being connected the free edges of the sheets. The portions each include a back panel and a series of J-shaped hooks. The seat assembly is characterized by an alignment device disposed on the portions to ensure that the J-shaped hooks are aligned when the J-shaped hooks are interleaved with one another such that the outboard portion is securely interconnected to the inboard portion. This ensures that the sheets are securely supported on the seat frame and that the sheets will remain supported on the seat frame during a deployment of the air bag.

Abstract: A noncompressive dewatering device generates air streams that can be used to remove water from cellulosic webs in an energy efficient manner. Further, a wet-pressed machine can be modified to economically produce low-density tissue with an energy/capital efficiency greater than that of the throughdrying process. For instance, a cellulosic web can be non-compressively dewatered from a post forming consistency to a consistency from about 25 percent to the water retention consistency by passing air through the web with an Energy Efficiency at least 10 percent greater than that achievable using vacuum dewatering at the same speed.

Abstract: A tissue sheet is made using a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web is conformed to the surface contour of a relatively coarse fabric to give the web a textured surface. By creating a pressure differential across the web of at least 30 inches of mercury and an air stream through the web of at least 500 SCFM/in.sup.2, the air press noncompressively dewaters the wet web to a consistency of about 30 to about 40 percent prior to a Yankee dryer. The web is dried to substantially preserve its three-dimensional, throughdried-like texture. The resulting web has an exceptionally high degree of bulk and absorbency not previously found in wet-pressed products.

Abstract: A method and system for planning repair or overhaul of an aircraft engine. This invention retrieves engine configuration data for a plurality of life limited parts for the aircraft engine, retrieves service requirement data for at least one of the plurality of life limited parts for the aircraft engine, and automatically determines a remaining life for the at least one of the plurality of life limited parts of the aircraft engine from the configuration data and the service requirement data.

Abstract: The present invention discloses a system and method for proactively monitoring risk exposure. In this invention, risk related information is received at an input knowledge source. A shared database stores the risk related information received at the input knowledge source. A plurality of domain knowledge sources formulates a decision on how the risk related information in the shared database affects a predetermined risk category. An output knowledge source generates a risk related report in response to the decisions formulated by each of the plurality of domain knowledge sources. A risk analytics router routes the risk related information in the input knowledge source to the shared database, the risk related information in the shared database to at least one of the domain knowledge sources, the decisions formulated from the domain knowledge sources to the shared database, and the decisions from the shared database to the output knowledge source.

Abstract: The method of treating sewer scum including combustibles and debris includes the steps of collecting the scum from sewage, delivering it to a perforated filter drum, continuously rotating the drum upon an inclined longitudinal axis, applying heated air under pressure to the exterior of the drum along its length inwardly of the perforations, discharging the debris continuously and collecting the filtered combustibles. Apparatus for filtering said scum includes an elongated cylindrical perforated drum rotatable on an inclined axis receiving scum at its upper end and discharging debris at its lower end. A cylindrical shell sealingly encloses the perforated portion of the drum for providing a pressure chamber above the drum and a collection chamber below the drum. An elongated air channel along the interior of the shell delivers high pressure heated air to said pressure chamber and filtered scum accumulates in the collection chamber.
