PURPOSE: To provide a hole-plugging printing method for a printed wiring board capable of satisfactorily filling a blind hole with a filling agent with no air bubble inside the hole, and a plate for the method.

During the filling of recesses (16) by welding, binding defects and cracks may appear.

Such treatment is achieved minimally invasively without the need for conventional filling materials and methods.

Applications for detecting clogging in a filter for fluids.

The device is capable of limiting clogging of the filter.

The method further includes executing a remedial operation to facilitate removal of the clogging condition (205) and determining if the clogging condition has been removed (206).

DPF performance: clogging of the DPF — total functional failure

Thus, clogging of the discharge opening (24) is advantageously prevented.

The resulting activity of the screen reduces blinding in use.

Reducing the blinding of mineral processing filters blinded with metallic ore fines by treating the blinded filters with an aqueous solution of an unblinding agent which solubilizes at least a portion of the ore fines.

In order to provide long periods of operation without blinding, a dead-end filter (30) has a reversible filter cloth (105) of conical shape.

Thereafter, the plugging material (31) is charged into the cells (3) of the honeycomb structure (1) by means of a plugging device (24).

The solution has a lanthanide salt dissolved therein and a pH between about 6 and 7 and includes an agent for bulking so as to enhance the plugging effect.

Disclosed is a method for plugging a leaking oil-gas pipe in deep sea.

Plugging a well, jurisdiction of Commissioner to award costs, order to plug, compliance, s.s.

A fluid plugging material (31) is fed on the mask or the same plane as the mask by means of a plugging material feeding device (23).

By lifting, the wash arm negates the sealing action of fatty build-up around its base which would otherwise impede its rotation.
