Abstract: A hybrid rocket engine is described that achieves stable, highly efficient hybrid combustion by having a core flow of fuel-rich gas generator gases, with the flow being surrounded with an annular injection of oxidizer. The fuel-rich gas serves to vaporize and decompose the oxidizer, such as nitrous oxide, and prepare it for effective, stable combustion. In one embodiment, this is done at the head-end of a combustion chamber. The combustion products can then be expanded through a nozzle to create thrust. The engine can be an upper stage engine that can include modular thrust chambers and an integrated aerospike nozzle. The thrust chambers can be arranged in an array that rings the top of the aerospike nozzle.

Abstract: A high survivability fluid flow sensor includes a sensor housing defining an interior space. A sensor probe has a first end disposed within the interior space. The sensor probe also includes a second end opposite the first end outside the interior space. At least one load cell is disposed within the interior space and is operatively engaged with the first end of the sensor probe. The load cell is configured to detect loading on the sensor probe as a result of fluid flow impinging on the sensor probe adjacent to the second end. The sensor is operable to capture fluid flow data history through an over pressure event via the sensor probe, which exerts pressure upon the piezoelectric load cell(s), thereby enabling analysis of the wave fluid dynamics.

Abstract: A method for monitoring the short-circuiting switching device of a three-phase motor (3) for driving vehicles, which is fed from a DC voltage source (1) via a controlled converter (2), wherein the short-circuiting switching device (5) actuated by a control logic (6) is connected to the inputs of the motor, and the motor currents and/or motor voltages are measured, and a predetermined test pattern, which is different from the voltage/current profiles during operation, is generated with the aid of the controlled converter (2) during a test phase and is supplied to the motor (3), the short-circuiting switching device is actuated for the activation thereof, the current and/or voltage profile is detected during the test phase by opening and closing of short-circuiting contacts and, on the basis of the current and/or voltage distribution in the individual motor phases, the correct open-ing/closing of the short-circuiting contacts is detected and evaluated.

Abstract: A method for executing safety-relevant and non-safety-relevant software components on a hardware platform comprising a computer, memory and a monitoring component that operates independently of the computer. The safety-relevant software component erects a memory protection against access of a non-safety-relevant function to at least one area of the memory of the safety-relevant function before execution of the non-safety-relevant software component, so that the non-safety-relevant software component does not have access to the areas of the memory being used for safety-relevant components. After the return from the non-safety-relevant component, the memory protection is deactivated and the monitoring function monitors the safety-relevant function for its proper operation.

Abstract: Systems and methods enable federation of search results. An identification of a first data source associated with a first schema is received by the system, the first data source comprising data of a first type. An identification of a second data source associated with a second schema is received, the second data source comprising data of a second type, the second type different than the first type. An identification of a plurality of fields for a results set user interface, a mapping of the data of the first type to a first field of the results set user interface, and a mapping of the data of the second type to the first field of the results set user interface, are accessed. Data of the first type and data of the second type are merged and provided for display in the first field on a user terminal.

Abstract: Disclosed is a device which is designed to improve the accoustics of a drum. The device has two halves, and it attaches about a hole formed in the drum head. One or both halves have portions which can be flared to a variety of degrees, e.g., 90 degrees, 180 degrees, 360 degrees or more.

Abstract: A system and method for intermixing the contents of two containers. The system includes a first container, a second container, and a connector for providing fluid communication between the first and second containers. The connector includes at least one resilient retention member for securing the first container to the connector. In addition, the connector accommodates standard vials containing, for example, medicaments, and prevents the unwanted discharge of the contents of the vial into the environment.

Abstract: A piston and piston rod for a rodless dispenser for extrudable material are configured such that compressive force exerted on the piston from a push chain causes a reactive torque to be created that locks the links of the chain together. The push rod is located away from the piston's geometric center.

Abstract: A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain obviates the need for an elongated piston rod used in conventional extrudable material dispensers.

Abstract: A method is provided for generating and distributing electricity via an electrical grid, wherein a fossil fuel plant and a renewable energy electricity generating station are interconnected with the electrical grid and are both operable to generate electricity output. The electricity output is directed from both the fossil fuel plant and the renewable energy electricity generating station to the electrical grid for distribution. Then, at the fossil fuel plant, at least a portion of the electricity output is directed to within the plant and utilized in generating hydrogen. The method provides further a reacting step wherein the generated hydrogen reacts with carbon dioxide to produce methane. Continued operation of the fossil fuel plant is conducted utilizing the produced methane as fuel, to generate electricity output, and also, capturing carbon dioxide exhaust and utilizing it in the reacting step.

Abstract: A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain exerts a compressive force on a piston rod connected to a piston at a point offset from the center line of the piston, causing the piston to rotate to lock the push chain. The amount of material remaining in a tube of extrudable material is enunciated by way of a contents indicator driven by the push chain.
