  • Patent number: 5527203
    Abstract: A method is disclosed for removing water soluble salts from a metal substrate in a wet blast system in which a bicarbonate abrasive is blasted in a pressurized water stream against the surface of the metal substrate to prepare the surface for the application of a coating. The method includes the steps as indicated in FIG. 3 in which a high pressure wet blast pressurized water and sodium bicarbonate abrasive is first applied by a nozzle (14) against the surface of the metal substrate with the water soluble salts being removed or neutralized. Iron salts are present where the metal substrate is of a ferrous material such as iron or steel. Next, pressurized water without abrasive is applied by the nozzle (14) against the surface of the metal substrate for washing the surface clean and removing the neutralized water soluble salts. The water for the wet blast system is of a very high purity characterized by a conductivity of between 0.5 and ten (10) micromohs/cm.

  • Patent number: 5326323
    Abstract: A stabilizing apparatus is provided for use with an oval gear meter. The oval gear meter for receiving material such that the quantity of material is measured by the meter. The meter having the characteristic of alternating acceleration and deceleration for a constant flow of material passing through the meter due to the eccentricity associated with the elliptic shape of the oval gear thereby causing excessive instability or oscillatory conditions with respect to the measured material. The stabilizing apparatus includes a first actuator secured to and synchronized rotationally with an oval gear. The first actuator receives rotational force from the oval gear representative of the quantity of material passing through the meter. A second actuator secured to and synchronized rotationally with a shaft. The second actuator is rotationally driven by force received from the first actuator for transferring rotational force to the shaft.

  • Patent number: 5323797
    Abstract: A rotating hose device for rotating and helically thrusting a high pressure hose and biased nozzle into a pipe for the purpose of cleaning the interior surface of the pipe. The rotating hose device is powered by converting linear torque from a rotating high pressure hose into linear thrust, forcing the high pressure hose and biased nozzle into the pipe, where the high pressure hose and biased nozzle travel through the pipe in a helical manner. The present invention more effeciently cleans conduit, pipe and other tubular members, by constantly positioning the biased nozzle against the interior surface of the pipe and avoiding the "streaking" effect left by prior art nozzles. The helical pitch of the rotating high pressure hose, speed and direction of travel of the high pressure hose are controlled through the alignment of the drive wheels in the rotary hose drive.
