Reactor coolant pump having improved dynamic secondary seal assembly

Patent Bice, C.D.; Campen, C.H.

This patent describes a pump having a stationary housing with pressurized fluid therein and a shaft with a rotational axis, a sealing arrangement disposed in the housing and sealably mounting the shaft relative to the housing. It comprises a pair of annular seal parts radially spaced from one another by a clearance gap and capable of translatory movement relative to one another, one of the seal parts having a cylindrical surface and the other of the seal parts having an annular groove which opens toward the gap and includes an inner cylindrical surface facing toward the cylindrical surface of themore »« less
Dynamic seal for well tools

Patent Jackson, G. D.

A dynamic seal for use between reciprocal concentric tubular members is disclosed herein and is especially adaptable for use in providing a dynamic seal between a movable piston and a sleeve in a downhole oil or gas well tool, such as a safety valve, a hydraulically actuated packer or a sliding sleeve. Each dynamic seal assembly comprises an elastomeric T-seal with cylindrical backup members positioned on either side of the central tip section of the seal member. The elastomeric T-seal is received within a central annular groove and a seal receptacle and the backup members are positioned within recessed ledgesmore »« less
Dynamic seal for subterranean well

Patent Tilton, F. T.; Salter III., M. C.; Weinberg, R. A.

An assembly for use in establishing sealing integrity between an inner and outer conduit in a subterranean well is disclosed. A multi-component seal assembly having a plurality of individual seal units is assembled on the exterior of an inner tubular conduit for insertion into the bore of an inplace tubular seal receptacle located in a subterranean well. The tubular conduit and associated seal assembly can be inserted into the bore and axial reciprocation of the tubular conduit relative to the seal receptacle is possible without damage to veeshaped primary elastomeric sealing elements during insertion, while sealing integrity is maintained withinmore »« less
LABYRINTH LIGHT SEAL SYSTEM FOR A LIQUID SCINTILLATION COUNTING APPARATUS SAMPLE CHANGING MECHANISM.

Patent Olson, R.E.; Ellyn, G.; Smith, R.E.
GAS SEAL

Patent Monson, H.; Hutter, E.

A seal is described for a cover closing an opening in the top of a pressure vessel that may house a nuclear reactor. The seal comprises a U-shaped trough formed on the pressure vessel around the opening therein, a mass of metal in the trough, and an edge flange on the cover extending loosely into the trough and dipping into the metal mass. The lower portion of the metal mass is kept melted, and the upper portion, solid. The solid pontion of the metal mass prevents pressure surges in the vessel from expelling the liquid portion of the metal massmore »« less
