Assignee:

Litton Resources Systems, Inc. - Alvin TX

International Classification:

G01V 106
G01V 138

US Classification:

181118

Abstract:

An air gun of the reciprocating shuttle type includes a split-ring sleeve valve that is expandable against the inner wall of a firing chamber. The sleeve valve encircles the shuttle body. The shuttle body and the sleeve valve include a set of air release orifices that are alignable with a corresponding set of air exhaust ports of the firing chamber.

Assignee:

Western Atlas International, Inc. - Houston TX

International Classification:

G01V 116

US Classification:

367154

Abstract:

The present invention discloses an apparatus for rotatably attaching a sensor to a cable. A cable mount having a groove about a substantial portion of its periphery is fixedly placed on the cable. A sensor mount having a key adapted to slide along the groove is rotatably placed on the cable in a manner which enables the key to remain in the groove when the sensor mount rotates about the cable.

Appl. No.:

6/180788

Inventors:

Richard C. Farris - Dickinson TX

Assignee:

Western Geophysical Co. of America - Houston TX

International Classification:

G01V 138
G01V 1137

US Classification:

181120

Abstract:

A shuttle valve is slidingly provided within a firing chamber. A shuttle valve actuation control chamber is mounted at each end of the firing chamber. Pressurized air applied to a control chamber at one end of the firing chamber drives the shuttle valve to the opposite end of the firing chamber. An air accumulator chamber having a pressurized-air inlet is mounted adjacent each control chamber. An air passageway having a choke interconnects the firing chamber with the air accumulation chamber. A poppet valve interconnects each accumulator chamber with the adjacent control chamber to selectively apply pressurized air to one or the other of the control chambers. A solenoid vent valve fluidly communicates with each shuttle valve actuation control chamber. A bypass line fluidly interconnects each control chamber with the solenoid vent valve at the opposite end of the firing chamber.
