Filed:

Jun 23, 1993

Appl. No.:

8/081563

Inventors:

Neal A. Clevenger - Cincinnati OH

Assignee:

Dover Corporation - New York NY

International Classification:

B65B 128

US Classification:

141 1

Abstract:

A manhole sealing device enables the recovery of vapors displaced from a tank during the process of filling a tank with fuel, through the manhole. The sealing device comprises a sealing gasket, which has an inflation chamber defined by two tubular walls. When the chamber is inflated, the gasket is distended to toroidal configuration capable of sealing engaging manhole inner diameters of a wide dimensional range. The sealing gasket is mounted on a lock-down bar what is clamped against the upper end of the manhole, using bolts that are also used in clamping the hatch cover for the manhole. Preferable the gasket is first inflated to centralize it relative to the manhole and then clamped in fixed relation relative thereto.

Abstract:

A fluid flow rate sensor, which may also be the basis of a valve for a fire suppression system, uses a sensing arm to convey motion of an obturation body or a valve closing member to a sensor system which evaluates the motion and generates a calibrated measure of the flow rate and/or an alarm signal in response if warranted. The obturation body and the valve closing member are capable of both rotation and translational motion, both of which are sensed using the sensing arm. The sensor system is isolated from the fluid within the valve.
