US Patent:

54049032, Apr 11, 1995

Filed:

Apr 28, 1993

Appl. No.:

8/054389

Inventors:

Todd W. Anderson - Cincinnati OH
Richard L. Fahl - Fairfield OH

Assignee:

Dover Corporation - New York NY

International Classification:

F16K 1704

US Classification:

1375143

Abstract:

A "smart vent" valve is mounted on a liquid storage tank employed in the transportation of liquid. The valve prevents overpressurization of the tank due to increases in vapor pressure and prevents discharge of liquid through the valve in response to pressure surges caused by accidental overturning of the tank. A valve member is provided for a vent opening. Sealing engagement is maintained between the valve member and the vent opening during a finite period of valve member travel caused by an increase in pressure within the tank. The rate of valve member travel is limited by hydraulic system in which hydraulic fluid is forced through orifices from one chamber to another. The high levels of pressure surges do not have sufficient duration to displace the valve member a distance sufficient to move it to a position in which the vent opening is unsealed and liquid could escape therefrom.

International Classification:

F16L 3720

US Classification:

2511499

Abstract:

An elbow coupler includes a linkage for locking the coupler to an adapter. The linkage has a resilient, laterally deflectable link that limits the forces applied to the linkage thereby preventing the components of the linkage from being overstressed. A spring loaded, blocking sleeve prevents the coupler from normally remaining upright on an adapter, unless it is locked thereon through use of the locking linkage. A flapper valve is interconnected with the blocking sleeve to the end that the valve is normally closed and then opened when the coupler is locked onto an adapter.

International Classification:

F16L 3500

US Classification:

285 38

Abstract:

A low profile locking mechanism for securing a lever arm of a coupler in a locked position interlocks with the side surface of the lever arm. The locking mechanism is formed from low cost resiliently deformable material that is protected against impact by the lever arm.

International Classification:

F16K 31126

US Classification:

251 612

Abstract:

A vent valve for a transport tank car is actuated by pressurized air from the tank cars brake system. The valve is opened by this pressurized air to permit flow of air, through a vent passageway, into or out of the tank. A bellows isolates the pressurized air system from the flow of air in the vent passage so that the braking air system will not be adversely affected by vapors from hazard products loaded in the tank.

Abstract:

Methods for manufacturing composite components having complex geometries are provided. In one exemplary aspect, a method includes laying up each of a plurality of laminates to an initial shape with a substantially planar geometry or a gently curved geometry. Then, a laid up laminate is formed to a final shape for each predefined section defined by the composite component to be manufactured. Thereafter, the laminates formed to their respective final shapes are stacked to build up the complex geometry of the composite component. Next, the composite component can be cured and finish machined as necessary to form the completed composite component.

International Classification:

Abstract:

A hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.
