Abstract: A kit contains mast modules that may be erected and connected in a variety of configurations to provide a barrier to accomplish any one or more of the following: guide traffic, protect and rope off an accident or crime scene, warn pedestrians and motorists of dangerous conditions, and shelter an area and/or first responders from sun and precipitation. Masts, coupling sleeves, coupling slots, slits and bases are interconnected to form a barrier.

Abstract: Systems and methods for processing content packages such as human-readable documents identify and analyze content type. Structural and logical evaluation of a Content package is performed, followed by analysis and indexing of concepts within the package. Analysis and identification of concepts and sub-concepts may be an iterative process. Concepts are indexed in accordance with different rule sets representing Different consumer needs and perspectives. Customers can then use the indices to navigate large groups of content packages based on the concepts contained within those packages and also on keywords associated with concepts.

Abstract: An integrated computer-implemented corporate information delivery system. A database stores research reports produced by and received electronically from brokerage firms. The database also stores corporate information about a number of corporations. Each item of corporate information is produced by and received electronically from one of the corporations about that corporation. Authorization information ("entitlements") specifies who is authorized to access each research report or item of corporate information. An entitlement subsystem allows the contributor of the research report or item of corporate information to dynamically change, on-line, the entitlement status of any or all users/subscribers. A research delivery module allows a user to submit a query and receive query results listing research reports and corporate information satisfying the query and that the user is authorized to access.

Abstract: A cover for a pressure sensor for indicating cracks in a hollow aircraft blade, the sensor having a shaft carrying a radiation source, with the shaft sliding in a housing between a first position with the radiation source within the housing and a second position with the radiation source external of the housing, the cover including a sleeve for positioning around the sensor and having an open end for engaging a shoulder of the sensor and having a closed end spaced from the sensor when the open end is engaging the sensor shoulder, and a plunger slidably mounted in the closed end and movable between an outer position and an inner position, with the plunger out of engagement with the sensor shaft when in the outer position and engaging the sensor shaft when in the inner position to move the shaft into the sensor and reset the sensor, with the sleeve being of a material absorbing the radiation of the source.

Abstract: The invention is a thermistor comprising a thermistor element, a fixed product of a resistive film on an axial surface of the thermistor element and a conductor material on the terminal surfaces of the thermistor element. The fixed resistive film extends to the peripheral edges of the axial surface, thereby influencing conductance from the thermistor element except at its terminal ends.

Abstract: A tank content gauging system including a plurality of radiation sources and a radiation detector mounted at a fuel tank, with the radiation detector positioned for receiving radiation from the sources and for producing an output which is an electrical analog of the detected radiation, a register for storing the detector output, a telemetry-on-demand switching unit for starting and stopping the detector operation from a point distant from the tank, a transceiver for sending "on" and "off" commands to the switching unit and receiving telemetry data from the register, a computer having the telemetry data and reference data as inputs for producing an output representing the quantity of fuel in the tank, and a display for indicating the quantity of fuel in the tank.

Abstract: A system for indicating cracks in a hollow aircraft blade, such as a helicopter blade. A system wherein a pressure differential is maintained within the blade with respect to the ambient atmosphere and including a pressure sensor for mounting on the blade in communication with the interior of the blade and having a member which moves in response to pressure changes within the blade, a beta radiation source mounted on the member and disposed for radiation transmission to a detector, a beta radiation detector for mounting on a nonrotating portion of the aircraft for receiving radiation from the source, and circuitry having the output of the detector as an input and providing an output which varies as a function of the position of the pressure sensor member for indicating the pressure condition within the blade. An improved beta radiation detector housing which substantially eliminates detector sensitivity to radar transmissions while maintaining sensitivity to nuclear radiation in the beta range.

Abstract: A composition having reduced gate smear is obtained from a selected polyamide, calcined calcium silicate and a selected toughening agent.

Abstract: Method and apparatus for continuously detecting cracks in aircraft blades while in flight. A hollow blade is sealed with a pressure differential, either above or below atmospheric. A reduction in the pressure differential such as results from cracks, is detected by a pressure sensor having a member which moves between a high pressure differential position and a low pressure differential position. A radiation source, typically a beta source, is carried on the member and moves from a shielded position to an unshielded position when the pressure differential drops. A radiation detector is mounted on a fixed portion of the aircraft and detects radiation from the source when the member moves to the unshielded position. The detector output may be used to operate a go-no go indicator providing a warning signal when the pressure differential falls below a predetermined value, or to operate an analog indicator providing an output varying as a function of the pressure differential.
