Patent number: 6216623Abstract: Each barge in a group of river-going tanker barges, has a double-hull construction to protect the inner hull and avoid collision-induced cargo spills. The space between hulls is partitioned to individual empty, dry compartments with a vertical, open bottomed, measuring tube fixed in each. A closed-bottom master tube is fixed in one compartment. All tubes have a quick-connect, above-deck, flange to receive an ultrasonic transducer thereon. A hand-held measuring instrument containing a computer and controls and information display contains a transducer which is selectively pulsed to periodically send ultrasonic signals down the tube, and receive echo signals, with elapsed time representing the depth of a signal reflector surface which is the master tube bottom or, for the measuring tubes, the bottom of a dry compartment or the surface of liquid in a leaking compartment. A unique bar code with each tube, distinguishes it and the barge from all others. The measuring instrument includes a code reader.Type: GrantFiled: October 1, 1997Date of Patent: April 17, 2001Assignee: Electromechanical Research Laboratories, Inc.Inventor: Larry C. Wilkins

Patent number: 5960823Abstract: A vacuum limiter valve assembly has a valve body screwed into an opening on a cargo tank. It has a relatively soft elastomeric, lightly spring-loaded seal closing the passageway through the valve body between the tank interior and the surrounding environment outside the tank. The relatively small area of the seal which would otherwise be exposed to tank cargo or vapors therefrom, is protected by a shield of material which is relatively inert and unaffected by most known chemicals, but also capable of a sealing function. The shield does not interfere with the normal sealing function, nor does it interfere with the opening of the vacuum limiter valve when needed to avoid development of excessive vacuum in the tank.Type: GrantFiled: July 21, 1998Date of Patent: October 5, 1999Assignee: Electromechanical Research Laboratories, Inc.Inventor: Larry C.

Patent number: 5900546Abstract: A railroad tank car containing liquid, has a tube through its top, with the closed lower end of the tube in the liquid. A float slidable along the tube exterior is magnetically coupled to an ultrasound reflector piston inside the tube so that, when the tube is in the liquid in the tank, the float determines the height of the piston inside the tube. An ultrasonic transducer atop the tube sends pulses down the tube and which are reflected by the piston to the transducer. A computer coupled to the transducer determines and displays the liquid level. The piston is cup-shaped with a known distance between reflecting surfaces for use in the computer to produce a display value corrected for temperature variations.Type: GrantFiled: July 24, 1997Date of Patent: May 4, 1999Assignee: Electromechanical Research Laboratories, Inc.Inventor: Larry C.
