A holesaw mandrel assembly has a mandrel with a first shanking end, a body, and a second extending end that includes a threaded spud to receive a holesaw. An output matching circuit section applies impedance matching to the amplified signal and outputs the resultant signal. In addition to dispersing asphaltenes, the composition of the present invention typically also increases demulsibility, reduces viscosity, reduces sediment formation, reduces surface fouling and reduces corrosion. When the screw rod is turned clockwise, it brings the cam sleeve to rotate at the same time while moves in the cam-shaped bore to mesh with the screw threads in the bore, causing the cam sleeve to axially move along the screw rod and finely shifts the adjustable jaw relative to the fixed jaw. There is also disclosed a rupturable capsule for retaining material to be dispensed. The second set of results may be transmitted back to the client application for display.
