Abstract:
A mobile robot communication system includes a remote unit, a repeater module and a control station. A cable connects the repeater module to the control station. The remote unit has a wireless receiver/transmitter for sending and receiving commands. The repeater module has a wireless receiver/transmitter for sending and receiving commands from the mobile unit. The control station is operable in communication with the repeater module for remotely sending and receiving signals. The cable is attached between the repeater module and control station for transmitting signals therebetween.
Abstract:
An automatic sample loader is for use in association with a mass spectrometer and at least one vial containing a sample. The loader includes a vial block, an insertion head, an insertion tube, a mechanism for pushing the sample out of the vial and a mechanism for moving the insertion head relative to the vial. The vial block has at least one vial cavity and each vial cavity is adapted to receive a vial. The insertion head is adapted to be sealingly engageable in the vial cavity. The insertion tube is operably connected to the mass spectrometer through the insertion head, such that the tube extends into the vial when the insertion head is sealingly engaged in the vial cavity. The pushing mechanism is adapted to push the sample out of the vial and into the tube. The moving mechanism is adapted to move the insertion head relative to the vial block from an engaged position to a disengaged position.
Abstract:
A blowout preventer handling apparatus including a frame structure, a carriage slidably supported on the frame structure, a raising frame pivotally supported on the carriage, and a positioner mechanism cooperatively connected to the raising frame for receiving the blowout preventer therein and for moving the blowout preventer upwardly-and-downwardly, rotationally, and side-to-side. A tray is slidably supported on the carriage so as to be movable between a first position away from the positioning mechanism to a position directly below the positioning mechanism. An outrigger assembly is selectively movable outwardly of an end of the frame structure.
Abstract:
To improve the quality of the demodulated signal without altering the form in which an AM radio wave is transmitted, the received amplitude-modulated signal is converted to a single-sideband signal, and the information signal demodulated from the phase term of this converted single-sideband signal.
Abstract:
The present invention is a method for reducing the slagging and fouling of the surfaces of the waterwalls, firebox, superheater, and reheater of the furnace of a coal-fired steam boiler. The process reduces the firebox exit temperature to below the specific ash melting temperature by injecting the following, either alone or in combination, into ports located in the upper section of the firebox: recirculated flue gas from downstream of the electrostatic precipitator, atomized water, or a sorbent water slurry. All of these materials have a lower temperature than the main flue gas or require additional heat for evaporation. Mixing these materials with the main flue gas from the furnace will not affect the coal combustion process, yet will reduce the temperature of any fly ash particles in the main flue gas to below the specific ash fusion temperature, and thus, prevent slagging and fouling within the furnace.
Abstract:
A method for ionizing a sample at ambient pressure including providing ionization-assisting molecules on a surface of a substrate, placing sample molecules on the surface of the substrate, and irradiating at least one of the sample molecules and the ionization-assisting molecules to produce ions of the sample molecules at or near atmospheric pressure. Accordingly, the system for ionizing sample molecules at or near atmospheric pressure is disclosed.
Abstract:
An integrated head assembly (100) is disclosed for a nuclear reactor. The preferred integrated head assembly includes a lift assembly (150) that supports the reactor vessel closure head (90) and integrated head assembly for removal, a separate support structure (202) supported by a ring beam (151) that sets atop the reactor vessel closure head, a shroud assembly (200), a seismic support system (300), a baffle assembly (500), a missile shield (400), and a CRDM cooling system. The CRDM cooling system draws cooling air into the baffle assembly, downwardly past the CRDMs (96), outwardly to upright air ducts (600), upwardly to an upper plenum (680), and out of the assembly through the air fans (190). In a second embodiment the integrated head assembly (1100) includes a missile shield (1400) and CRDM cooling system (1600) that permits access to individual CRDMs from above.
