Abstract: A connector assembly includes a subsidiary circuit board, connectors, and an interposer assembly. The subsidiary circuit board includes opposite sides. The connectors are mounted to the opposite sides of the subsidiary circuit board and are electrically coupled with the subsidiary circuit board. The connectors are configured to mate with mating connectors. The interposer assembly is joined with the subsidiary circuit board. The interposer assembly includes a dielectric housing and elongated contacts that extend between opposite outer ends along a vertical axis and are held by the housing. The interposer assembly mates with the subsidiary circuit board and is configured to mate with a main circuit board such that the outer ends of the contacts electrically couple the connectors mounted to the subsidiary circuit board with the main circuit board.

Abstract: Applying pulses to liquid being injected into wells makes the ground/liquid formation more homogenous, and more penetrative. A system for automatically creating the pulses is described, in which a piston is acted upon by the pressure differential (PDAF) between the supplied accumulator pressure and the formation pressure. The changing levels of the PDAF as the pulse-valve opens (and the PDAF falls) and as the pulse-valve closes (and the PDAF rises) are harnessed to actuate an inhibitor that restrain movement of the valve-piston, and delays opening and/or closing of the pulse-valve. The pulse-valve is engineered to open explosively, and thus create penetrative porosity-waves in the formation. The system includes a pressurized-gas accumulator, and injection-check-valve which can maintain pulsing even when the ground is not saturated, and the static injector, which allows non-pulsed injection only when the ground is non-saturated.
