Abstract:
PROBLEM TO BE SOLVED: To detect a peroxide or a superoxide included in a sample by using neutrons. SOLUTION: This system for detecting a compound included in the sample is equipped with a neutron source, at least one γ-ray detector installed close to the sample, and a signal processor. The neutron source sends a neutron beam toward the sample. The γ-ray detector collects γ-rays discharged from the sample, and the signal processor identifies a compound included in the sample based on γ-rays collected by the γ-ray detector. The compound to be identified is selected from a group comprising peroxides and superoxides. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A rotor (12) for an electric machine (10) includes a rotor disc (24) extending radially outwardly from a central axis (18) of the rotor (12) and a magnet retention band (30) including a plurality of magnet retention tabs (32). The magnet retention tabs (32) extend radially from the magnet retention band (30) and axially along a length of the magnet retention band (30). The magnet retention band (30) is secured to the rotor face (24) via a retention means and extends substantially axially therefrom. A plurality of permanent magnets (14), each permanent magnet (14) of the plurality of permanent magnets (14) are located at the magnet retention band (30) between adjacent magnet retention tabs (32) and are radially and circumferentially retained between the magnet retention tabs (32) and the magnet retention band (30).
Abstract:
An example journal air bearing (10) for a rotatable shaft (26) of an air cycle machine (30) includes a top foil (14) configured to receive a rotatable shaft (26), and an intermediate foil (18) radially outboard the top foil (14). A journal sleeve (34) is radially outboard the intermediate foil (18). The top foil (14) and the intermediate foil (18) establish apertures configured to communicate fluid between a first position radially inboard the top foil (14) and a second position radially outboard the intermediate foil (18).
Abstract:
A resource recovery system includes a capture container located at a desired surface defining a capture volume between the surface and an interior of the capture container. One or more hole-making devices are located in the capture container to excavate soil from at least one hole in the surface. A heater located in the hole making device heats the excavated soil, releasing one or more compounds from the excavated soil. The capture container is configured to capture gas and/or liquid compounds released from the excavated soil. A method of resource extraction from soil includes covering a desired surface with a capture container defining a capture volume between the desired surface and an interior of the capture container. Soil is excavated from a hole in the desired surface into the capture volume with an auger. The auger heats the excavated soil thereby releasing one or more compounds into the capture volume.

PROBLEM TO BE SOLVED: To provide a gear box deoiler with a pre-pressure component.SOLUTION: A gearbox includes an inlet configured to receive a mixture of air and oil from an external source, and a deoiler. The deoiler includes: a shaft including an inlet passage and an outlet passage both of which are formed on an inner portion of the shaft and separated from each other; a separator unit coupled to and surrounding a portion of the shaft and including an inlet and an outlet; and a pre-pressuring component coupled to the shaft that increases the pressure of the mixture of oil and air to form a pressurized mixture and provides the pressurized mixture to the inlet of the separator unit.

PROBLEM TO BE SOLVED: To provide a further gearing assembly that rotatably connects a prime mover with a motor-generator.SOLUTION: This mechanical transmission assembly receives an input rotating at a first rotational speed and provides an output rotating at a second rotational speed. The mechanical transmission 56 selectively adjusts the second rotational speed. The input is provided by a prime mover. The output is provided to a hydraulic pump assembly that rotatably drives a motor-generator 50. A method of driving the motor-generator 50 with a prime mover comprises: driving a transmission 56 with an input shaft 70 from a prime mover. The input shaft 70 rotates at a first rotational speed. The method drives a hydraulic pump 58 with a first output shaft 72 from the mechanical transmission 56, The shaft 72 rotates at a second rotational speed. The method drives the motor-generator 50 with the hydraulic pump 58; The method selectively adjusts the transmission 56 so that the first rotational speed is different from the second rotational speed.
