Filed:

Jul 1, 1985

Appl. No.:

6/751242

Inventors:

Robert A. Levine - Westminster CA
Danny F. Davis - Westminster CA
Anthony W. Cordeiro - Huntington Beach CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

G01N 2700

US Classification:

73432R

Abstract:

An oxygen content sampling system is disclosed. The system includes an oxygen probe and monitor. The oxygen probe and interconnecting cable pass through a housing adapted to receive and protect the probe during periods of non-use.

Filed:

Feb 9, 1990

Appl. No.:

7/478114

Inventors:

Robert A. Levine - Westminster CA
William M. Croke - Huntington Beach CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

G01F 2500

US Classification:

73 1H

Abstract:

An actuator for a liquid level sensing switch, particularly useful for testing level sensing switches on storage tanks and tanker cargo tanks. The actuator includes an elongated rod which is slidably supported on and extends through a two part body which may be supported on a flange or a deck portion above the tank. An elongated flexible cable interconnects the rod with a float member of the level sensing switch whereby the actuator rod may be pulled upward to effect movement of the float while, in the normal non-activated position of the actuator, the float may move freely between its limit positions for sensing liquid level in the tank.

Appl. No.:

7/155406

Inventors:

Robert A. Levine - Westminster CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

E02B 1504

US Classification:

210170

Abstract:

Crude oils and other oleaginous substances which have washed onto and socket thoroughly into coarse bottom sediments such as sand beaches and sediments forming the bottom of certain holding ponds may be released for recovery by mechanical or hydraulic plowing of the relatively loose sediments followed by hydraulic agitation of the sediments to permit the substances to float to the surface of the body of water. Shallow water beach areas may be plowed by a conventional crawler tractor having an array of ripper teeth fitted with hydraulic jet nozzles for severaly agitating the sands which are plowed by the ripper teeth. A submersible pump or pump intake is preferably supported spaced from the normal path of the tractor and in the body of water to collect relatively clean water for discharge through the nozzles. A nozzle array may be mounted on a manifold supported from a flowing vessel for vertical and angular adjustment relative to the bottom sediments utilizing the body of water as a source of hydraulic plowing and agitating fluid. An array of nozzles may include an angled nozzle having a generally planar jet pattern which acts to cut or plow the sand ahead of a full conical jet nozzle which thoroughly agitates the plowed or turned over sand to free the oil.

International Classification:

B01D 2100

US Classification:

210747

Abstract:

Crude oils and other oleaginous substances which have washed onto and soaked thoroughly into coarse bottom sediments such as sand beaches and sediments forming the bottom of certain holding ponds may be released for recovery by mechanical or hydraulic plowing of the relatively loose sediments followed by hydraulic agitation of the sediments to permit the substances to float to the surface of the body of water. Shallow water beach areas may be plowed by a conventional crawler tractor having an array of ripper teeth fitted with hydraulic jet nozzles for severely agitating the sands which are plowed by the ripper teeth. A submersible pump or pump intake is preferably supported spaced from the normal path of the tractor and in the body of water to collect relatively clean water for discharge through the nozzles. A nozzle array may be mounted on a manifold supported from a floating vessel for vertical and angular adjustment relative to the bottom sediments utilizing the body of water as a source of hydraulic plowing and agitating fluid. An array of nozzles may include an angled nozzle having a generally planar jet pattern which acts to cut or plow the sand ahead of a full conical jet nozzle which thoroughly agitates the plowed or turned over sand to free the oil.
