An improved foil thrust bearing includes a cooling fluid flow turbulence generating disk placed between other foil thrust bearing elements, such as thrust bearing elements and underspring elements. The inventive turbulence generating disk generally provides improved transfer of heat through the foil and into the cooling fluid of foil thrust bearings that may be used for high rotor speed applications. It accomplishes this by improving the transfer of heat through the foil and into the cooling flu...

A tilting pad bearing arrangement (10) (FIG. 1(a)) includes an array of bearing pads (15.sub.i) supported on a carrier (16). For each pad, the carrier pad surfaces have cylindrically concave recesses (28.sub.i, 29.sub.i), respectively formed therein with their axis orthogonal to each other. Linkng means (30) has opposite faces of cylindrically convex form conforming to the recesses to make sliding contact therewith, load is transmitted by way of an area, rather than line or point contact, reduci...

A bearing assembly for supporting a rotatable shaft comprises a number of bearing pads supported in a housing and the mutually engaging surfaces of each bearing pad and the housing are two surfaces of closely similar shape.

The tilt pad journal bearing assembly includes a conduit within the bearing housing for supplying lubricant hydrostatically to each tilt bearing pad. The conduit includes a flexible segment coupled at respective opposite ends to the tilt pad and to a quick connect/disconnect coupling extending through an aperture in the side wall of the bearing housing. A supply line is coupled to each supply conduit adjacent the side wall by the quick connect/disconnect coupling. The flexible segment within the...

A system for removing sludge that may be deposited on a tube sheet of a steam generator. Headers are arranged at the elevation of the sludge to be removed establishing a circumferential fluid stream at that elevation. A fluid lance is moved along the line between the headers emitting a fluid jet perpendicular to the line of movement of the fluid lance at an elevation substantially corresponding to the level of sludge deposits. The fluid jet forces the sludge to the periphery of the tube sheet wh...

Triangular net-like arm restraining members, one for each side of an aircraft ejection seat, extend during the first phase of ejection so that each has an upper corner near the top of the back portion of the seat, a front corner near the front of the horizontal seat portion, and a lower corner near the junction of the back and seat portions. The upper corner of each restraining member is anchored near the top of the back portion, at its side thereof. The restraining members are normally furled a...

Hydrodynamic plane thrust bearing (26) for a generator (10), preferably operable with a water turbine, with a rotor (12), a track ring (30) rotating with the shaft (20) of the rotor (12), and a bearing segment (32) not rotating with the shaft (20) of the rotor (12) and supported on a bearing housing (24), characterized in that the track ring (30) substantially consists of a plastic matrix with reinforcing fibers embedded therein.

A steam generator includes a vertically elongated housing. A horizontal tube plate and a U-shaped tube bundle are disposed in the housing. The tube bundle has mutually spaced apart legs defining an intermediate space therebetween and tube ends disposed in the tube plate. The tube plate has a horizontal blow-down line formed therein. The tube plate has holes formed therein leading from the blow-down line into the intermediate space.

To provide a movement-detecting altimeter designed so as to be capable of avoiding excessive accumulation of errors. The movement-detecting altimeter has a movement dependent altitude updating unit which updates an indicated altitude when a moving condition is maintained, and which avoids updating of the indicated altitude when the moving condition is not maintained. The movement dependent altitude updating unit has an estimated altitude computation section which obtains an estimated altitude by...

A multi-pad, fluid film thrust bearing has the pads suspended from the carrier ring on hydrostatic oil pressure regions. The oil is pressurized hydrodynamically by relative rotation between a load surface and the bearing surface of each pad; and the oil is passed through each pad to a rear cavity where the hydrostatic pressure region is established. A manifold interconnects all of the hydrostatic pressure regions for the individual pads in order to average the hydrostatic pressures and provide f...
