A compressor comprises a sealed chamber to which a suction pipe and a discharge pipe are communicated, a motor unit fixed in the sealed chamber and consisting of a stator and a rotor for generating rotating force by electromagnetic interaction between the stator and rotor, and a compression unit sucking, compressing and discharging compressible fluid according regular volume change and opening/closing of valve caused by rotating force of the motor unit, wherein the compression unit is disposed i...

A method for welding a sleeve within a tube of a steam generator, the sleeve being in close contact with the tube. A welding head of a weld head apparatus is positioned within the tube at a predetermined weld site, a laser beam is directed to the welding head, the beam is focused with a focusing means, the focused laser beam is reflected with a welding mirror means into contact with a portion of the sleeve to be welded to the tube, the welding mirror means is maintained a predetermined focal dis...

A method and system for controlling atmospheric conditions within a building. A conditioned fluid is supplied inside of the building and one or more atmospheric parameters in various locations inside of the building are sensed. An empirical atmospheric map is then generated and compared to a template atmospheric map. Pattern differentials are identified therebetween and corrective action to reduce the pattern differentials is determined. One or more of the quantity, quality, and distribution of ...

An angular contact bearing is mounted within a housing and a shaft is positioned within the bearing such that an annular space is provided between the bearing and the shaft. A mounting ring of elastomeric polymer is positioned over the shaft and against the bearing inner ring such that a portion of the mounting ring is between the bearing inner ring and the shaft, centering the shaft within the bearing and reducing radial free play. The mounting ring is compressed axially, against the bearing, s...

A vessel comprises a cylindrical hull (10) containing a structure (11) carrying machinery (M) supported from the hull (10) by electromagnetic levitation means (12-17) that maintain electromagnetic forces between flux gaps (24) which are arranged to extend radially of the adjacent hull (10) curvature and longitudinally of the hull (10). In this manner, the transmission of noise from the machinery (M) to the hull (10) is obviated so as to reduce the detectable acoustic signal emitted by the vessel...

The invention concerns a communications device incorporated into a doll-like figure with at least one microphone, at least one speaker and communications module for exchange of data with a digital data network. The invention thus proceeds from a digital telephone, preferably a videophone. The invention creates a communications device suitable for recording and reproducing other signals in addition to conventional data, particularly sound signals. The doll-like figure containing the communication...

The invention is a valve that prevents blow-outs through a control line while simultaneously allowing bi-directional flow or pressure transfer through the control line. The invention comprises a shuttle valve disposed in the control line.

A system and method are described for spacing objects within a constraint. In one embodiment, data that defines the constraint and a set of spacing parameters that indicate how to space objects across the constraint are received. Further, a grid type from a plurality of grid types is selected. Each such grid type is associated with one or more grid attributes. A grid of the selected grid type is then mapped onto the constraint.

An actuator having a body defining an internal cavity and a gland disposed within the cavity, the gland being secured against movement relative to the actuator body in a direction along the internal cavity by a securing element located in an opening of which respective parts are defined by the actuator body and the gland, and which allows insertion of the securing element into the opening along a substantially linear path.

An indicating apparatus of photographing conditions within a finder of a camera, including at least one composite indicator symbol which has a plurality of indicating elements and which represents a single symbol or figure as a whole in the finder field of view, said composite indicator symbol indicating the associated photographing conditions.
