Patent ID: 7078619

Claim:
An enclosure for environmentally isolating seismic signal processing circuits, said enclosure comprising an assembly of first and second housings for respective chambers, a first chamber of said first housing having internal access through a first environmental partition that may be selectively detached repeatedly from said first housing, a second chamber respective to said second housing contiguously adjacent said first partition, said first partition being a structurally integral element of said second housing, said second chamber having internal access through a second environmental partition that is selectively detachable from said second housing, a first signal conduit traversing said first partition for operative connection at one end with signal processing circuitry within said first chamber and with a first conduit connector at an opposite end, and a first conduit connection union traversing said second partition, said first connection union having an inside connector compatible with said first conduit connector and an outside conduit connector compatible with a seismic signal conductor cable.
