摘要:
An internal spring system resiliently supports a mattress in an item of furniture. The spring system includes a system of sinuous springs arranged between upper and lower wire grids. A movable extender assembly is mounted on the grids to accommodate a longitudinal shift between the upper and lower grids during folding of the spring system between open and closed positions.

A system includes a turbomachine. The turbomachine includes at least one rotor disk. The system also includes a rotor disk heating system configured to resistively heat at least a portion of the at least one rotor disk via an electrical current or voltage applied to the portion of the at least one rotor disk.
摘要:
The present invention provides systems and methods of removing heat from internal areas of a turbomachine. Embodiments of the present invention may incorporate a suction device and a control system. Operatively, these elements may collectively discharge remnants of a heated fluid and/or gas from those internal areas.

A flooring system for use in thermal and/or acoustic floor systems is provided where the flooring system mitigates external forces from a shock/blast wave. The flooring system includes a foam layer and filler material that includes micro and/or nano structures strategically dispersed in the foam layer. The micro and/or nano structures mitigate a magnitude of the external forces propagating through the foam layer.

A ventilator includes a compressor, a storage vessel, a valve assembly communicating with the compressor, the storage vessel, and an inhalation line. A controller directs the valve assembly between a storage configuration where ventilation gas is delivered from the compressor into the storage vessel, and a delivery configuration where ventilation gas is delivered from the storage vessel to the inhalation line. The controller is coupled to a pressure sensor for detecting a first pressure within the storage vessel when the valve assembly is directed to the delivery configuration, and detecting subsequent pressure while ventilation gas is delivered from the storage vessel to the inhalation line, the controller determining the volume of ventilation gas delivered to the patient based at least in part on the difference between the first pressure and the subsequent pressure.

Disclosed herein is an approach that uses a motor protection system to assist in determining power plant metrics. In one aspect, a motor protection system obtains operational data from motor-driven sub-processes operating within a power plant. A controller receives the operational data and determines power plant metrics that may include net power plant output and costs each of the motor-driven sub-processes has on the overall operation of the power plant. In another aspect, the controller may partition the power metrics into one or more user-specified groupings for viewing thereof.

Systems and methods for controlling a gas turbine are disclosed. The gas turbine can include a compressor oversized in airflow capacity and one or variable blade rows to control the airflow into the compressor. The position of the variable blade rows can be controlled according to a nominal variable blade row schedule that is defined to throttle down the variable blade rows to provide nominal flow into the compressor. The positions of the variable blade rows can be adjusted from the nominal positions set forth in the variable blade row schedule pursuant to a request to operate the gas turbine system in either a controlled output mode or in a frequency compensation mode.

A method for preventing damage caused by high intensity light sources to optical components includes annealing the optical component for a predetermined period. Another method includes etching the optical component in an etchant including fluoride and bi-fluoride ions. The method also includes ultrasonically agitating the etching solution during the process followed by rinsing of the optical component in a rinse bath.
