Abstract: A metal gasket for sealing a three-component joint structure in which first and second joint members are disposed in confronting relation so as to align their respective holes with each other and in which an outer peripheral portion of a third joint member is fitted in a recess in the confronting surface of the first joint member. The metal gasket has an opening and is adapted to be placed between the first and second joint members so as to align the opening with the holes of the two joint members. The metal gasket also has, at a position near the opening, a stepped portion defined by first and second bends engageable with the first and second joint members, respectively, as the metal gasket is placed between the two joint members. As the first and second joint members are tightened so as to clamp the third member and the metal gasket, the stepped portion is deformed so as to bring the second bend to a position confronting the third joint member.

Abstract: A tubular connector, such as used with a liquid sight monitor, having a plurality of internal deformable ridges for bearing against the external surface of the tube of the monitor. Hence, it accommodates to a range of sizes and irregular tube shapes. The connector is made of a material that in a thick dimension is not deformable, but in a small dimension is deformable, such is Teflon FEP. The body is thick enough to be rigid, whereas the ridges are complaint, more so in a direction toward the mounting end of the connector or end of the tube. Pressure leakage form the liquid system to which the sight monitor is attached increases the pressure seal of the ridges with respect to the surface of the tube. Concentric tube sight monitors are connected to their systems using a connector having, in addition to the set of ridges for accommodating to the internal tube in the manner just described, a second set of ridges for conforming to an external tube.

Abstract: A shaft seal for sealing a rotating shaft relative to a panel or wall of a device from which the shaft extends. The shaft seal has a tubular housing including a packing gland for shaft packings which is floatingly mounted to a wall or panel of the device by an annular diaphragm. A bushing in the bore of the tubular housing causes the tubular housing to move bodily as permitted by the floating mounting when shaft run-out occurs. A connection between the panel and the tubular housing limits rotation thereof resulting from torsional forces derived from shaft rotation. A unitary structure fixed to the shaft for rotation therewith and mounted adjacent an outer end of the tubular housing coacts with an annular thrust washer fixed to said end of the tubular housing to absorb the loads applied to the annular diaphragm and tubular housing acting axially of the shaft.
